_A Successful Korean Defense_[296]

[296] Unless otherwise noted, the material in this section is derived from: 1stMarDiv ComdDs Oct-Nov 52; 1stMarDiv PIRs 737–738, dtd 31 Oct-1 Nov 52; KMC Regt UnitRpts 238–244, dtd 24–30 Oct 52.

In both the early and late October outpost battles the Chinese had attempted to seize critical terrain on the flanks of the 1st Marine Division. Although the majority of these attacks failed, the enemy had acquired six outposts early in the month--three in the western Korean Marine Corps sector and three north of the right regimental line. On the last day of October, two hours before midnight, the CCF again struck the Marine left flank. This time their efforts were directed against four outposts that screened Hill 155, the most prominent terrain feature in the entire KMC regimental zone. The fighting that developed was brief but very sharp and would be the most costly of all KMC clashes during this third winter of the war.

The latest enemy attack came as no real surprise to Korean Marines of the 5th Battalion, occupying COPs 39, 33, and 31 in the northern regimental sector, or 2d Battalion personnel at COP 51 in the southern (western) half of the MLR. (Map 19.) The four outposts assisted in defense of the MLR (particularly Hill 155 just inside the MLR), afforded observation of CCF approach routes, and served as a base for friendly raids and offensive operations. Hill 155 overlooked both the wide Sachon Valley and Chinese frontline positions to the west. This critical Korean hill also commanded a view of the Panmunjom peace corridor, Freedom Gate Bridge, and the Marine division area east of Line JAMESTOWN in the KMC sector. Hill 155 had further tactical importance in that it protected the left flank of Paekhak Hill, the key ground in the entire 34-mile expanse of JAMESTOWN within 1st Marine Division territory.

Actually, the probability of a determined enemy attack against the four outposts had been anticipated since early October following CCF seizure of three positions (former COPs 37, 36, and 86) in their strike against the KMC regimental OPLR. The enemy had then proceeded to organize an OPLR of his own with the two northern outposts, COPs 37 and 36, and informally occupied another position to the south and one toward the north in the vicinity of COP 39. “With this OPLR once firmly organized, the enemy will have an excellent jump-off point towards our OPs 39 and 33, his next probable objectives,” KMC officers reasoned.[297]

[297] KMC Regt UnitRpt 216, dtd 4 Oct 52, p. 2.

Sporadic probes throughout the month in the COP 39 and 33 areas indicated continued enemy interest in the positions. COP 51, to the south, was considered another likely target because of its location immediately east of COP 86, previously annexed by the CCF.

Prior to attacking the four outposts on 31 October, the Chinese had signaled their intentions by sharply stepping up artillery and tank fire against the sector. During the 24-hour period ending 1800 on 30 October, a total of 1,881 rounds crashed on KMC positions, most of these against the two northern outposts, COPs 39 and 33. Nearly 1,500 rounds fell the next day. More than 50 sightings of enemy troops and weapons in the forward area were also reported. By contrast, during the previous week less than 15 observations of enemy activity had been made daily and, on the average, only about 200–340 rounds of fire had fallen in the entire sector. Despite this comparatively moderate rate of hostile fire, at least one Korean Marine was killed and three wounded in late October from well-placed Chinese mortar or artillery rounds striking the outposts.

After the two days of heavy shelling, the regiment warned in its daily report issued only two hours before the full-scale attack began:

The enemy has made a consistent two-day effort to destroy friendly outpost positions. Last night, at 1830, two enemy companies were observed in an apparent attempt to attack OPs 39 and 33. Artillery fire broke up the attempt, but continued enemy artillery today indicates further attack is probable tonight. If enemy artillery preparation is indicative, a simultaneous attack against outposts 39, 51, 33, and 31 can be considered probable....[298]

[298] KMC Regt UnitRpt 243, dtd 31 Oct 52, pp. 5–6.

These earlier observations and predictions as to the enemy’s action were shortly confirmed when the CCF launched its new ground attack.

Beginning at 2200,[299] the enemy delivered an intensive eight-minute 76mm and 122mm artillery preparation against the four outposts. Chinese assault forces from four different infantry regiments then launched a simultaneous attack on the positions. Moving in from the north, west, and south, two CCF companies (3d Company, 1st Battalion, 581st Regiment and 2d Company, 1st Battalion, 582d Regiment) virtually enveloped the northern outpost, COP 39. Two more CCF companies (unidentified) lunged against the two central outposts, COPs 33 and 31, a company at each position.[300] The southern and most-heavily defended post, COP 51, where a company of Korean Marines was on duty, was assailed by four Chinese companies (4th Company, 2d Battalion, 584th Regiment; 4th and 6th Companies, 2d Battalion, 585th Regiment; and 1st Company, 1st Battalion, 585th Regiment). Even though the enemy exerted his strongest pressure against COP 51, the position held and the Chinese broke off the attack there earlier than at the other outposts.

[299] The attack on the 31st took place after the KMC 5th Battalion had taken over the right regimental sector, at 1700, from the 3d Battalion. The Chinese often deliberately timed their outpost attacks to coincide with a relief of lines. Company personnel of both the 5th and 3d Battalions were on line during the fighting. KMC Regt UnitRpts dtd 1 Nov 52, p. 4; 245, dtd 2 Nov 52, p. 4.

[300] KMC Regt UnitRpt 244, dtd 1 Nov 52, pp. 1, 4. A different account as to size of attacking units is given in Maj Kang Shin Ho, ROKMC ltr to Dir, MCHist, HQMC, dtd 30 Apr 70, which states two reinforced enemy companies assaulted COP 33 and an estimated enemy battalion struck COP 31.

At COP 31 a heavy fire fight raged until 0155, when the defending KMC platoon halted the Chinese and forced them to make a partial withdrawal. To the northwest, at COP 33, the enemy encountered less resistance from the two squads manning the outpost. The Chinese achieved some success in penetrating the defenses and occupied several positions. After heavy close fighting and friendly artillery support, the Koreans expelled the invaders at 0515.

The enemy’s efforts appeared to have been most successful, temporarily, at COP 39, the northern post and one nearest to Hill 155. Although the Chinese wrested some ground from the KMC platoon, artillery fires continued to punish the enemy and by 0410 had forced him to pull back. A small hostile force returned at 0600 but after a 15-minute exchange of small arms it left, this time for good. At about this same time the last of the Chinese had also withdrawn from the two central outposts, 33 and 31.

In terms of sheer numbers, the enemy’s strongest effort was made against COP 51. This was the most isolated of the Korean positions and, at 2,625 yards, the one farthest from the MLR. Ironically, in the week preceding the attack COP 51 was least harassed by hostile artillery although it had received 20 rounds of 90mm. tank fire, more than any other position. On the 31st, elements of three companies struck the southwestern trenches and defenses, while a fourth attempted to break through from the north. As it turned out the action here was the least intense of the outpost clashes. After initial heavy fighting the Chinese seemed reluctant to press the assault even though they vastly outnumbered the Korean company deployed at the outpost. In the early morning hours the enemy broke contact and by 0330 had withdrawn from COP 51.

During the night approximately 2,500 rounds of CCF artillery and mortar fire lashed the positions. Korean Marines, aided by friendly artillery, repelled the assault and inflicted heavy casualties on the enemy. Supporting fires included more than 1,200 rounds of HE shells from the KMC 4.2-inch Mortar Company. Chinese casualties were listed as 295 known killed, 461 estimated wounded, and 9 POWs. Korean Marine losses were 50 killed, 86 wounded, and 18 missing.[301] By first light the Korean outposts had thrown back the enemy’s latest well-coordinated attack. This ended the last significant action of October in the 1st Marine Division sector.

_Six Months on the UNC Line_[302]

[302] Unless otherwise noted, the material in this section is derived from: Barclay, _Commonwealth_; Cagle and Manson, _Sea War, Korea_; Clark, _Danube to Yalu_; Field, _NavOps, Korea_; Futrell, _USAF, Korea_; Walter G. Hermes, _Truce Tent and Fighting Front--United States Army in the Korean War_ (Washington: OCMH, DA, 1966), hereafter Hermes, _Truce Tent_; Miller, Carroll, and Tackley, _Korea, 1951–1953_.

The KMC Regiment’s battle in late October marked the end of two months of heavy fighting in the division sector. October had witnessed the most intense combat in more than a year. As the third Korean winter approached outpost clashes and small unit actions along the rest of the UNC frontline began to slacken. During November and December, neither side appeared eager to pursue the offensive. Chinese aggressiveness declined noticeably.

Despite other action initiated by the enemy, the I Corps sector remained the chief Communist target. On 19 November, the British 1st Commonwealth Division successfully withstood what was initially a company-size attempt to capture the Hook. In sharp fighting between 1900 and 0430, Black Watch and reinforcing Canadian units repulsed a determined battalion-strength CCF assault, killing more than 100 Chinese.[303] Marine and I Corps artillery units fired almost continuously throughout the night in support of the Hook defenders. Fighting flared again, briefly, in December in the I Corps sector when Chinese soldiers attempted to overrun outposts on the Imjin River line, but were thrown back by the ROK 1st Division. The enemy then tried to seize key terrain forward of the U.S. 2nd Division, but was again halted.

[303] For details of this action see Canadian Department of National Defence ltr to Dir, MCHist, HQMC, dtd 8 Jan 70 in v. V, Korean comment file.

Elsewhere before the end of the year, the CCF captured one outpost in the IX Corps area, to the right of I Corps, but suffered a telling defeat at the hands of the Ethiopian battalion during an attempt to crack this sector of the U.S. 7th Division line. After a brief fire fight the Chinese were forced to withdraw, leaving 131 CCF dead in the Ethiopian positions. North Korean efforts to seize critical ground in the X and ROK I Corps sectors, at the far eastern end of the EUSAK line, was similarly broken up by the U.S. 40th and ROK 5th Divisions.

By the end of 1952 General Van Fleet had not only revitalized his defenses with recent rotation of frontline units but had also strengthened his line by inserting another division in the critical and long-troublesome Chorwon-Kumhwa sector of IX Corps, on the I Corps right flank. With these changes by late December there were 16 EUSAK divisions on line--11 Korean, 3 U.S. Army, 1 Marine, and 1 British Commonwealth--plus 4 divisions in reserve (1 Korean and 3 U.S. Army). Nearly 75 percent of the UNC line had been entrusted to Republic of Korea units. Their performance was a tribute to growing ROK military proficiency and justified the EUSAK decision to assign to ROK troops a greater role in the Allied ground defense.

The slow pace of infantry action during the last two months of 1952 continued into the new year. Raids by small UNC units highlighted the limited combat during January and February. During the following month the battlefront tempo accelerated, due in part to expanded patrol activities. A number of sharp clashes in No-Man’s-Land resulted in several Communist setbacks but led the enemy to make an increased use of ambushes. These traps initially caught the UNC troops by surprise, inflicting heavy casualties on them. But by far the most severe fighting of the new year resulted when the Chinese renewed their fierce outpost and main line of resistance attacks in March.

Again, the western I Corps sector was the major combat area as enemy pressure mounted along the front. This was believed due, in part, to the “growing Chinese sensitivity to the I Corps raids”[304] as well as an attempt by the CCF to regain the initiative as they began to send out larger forces to probe and assault UNC positions. On 17 March, the Chinese launched a battalion-size attack against Hill 355 (Little Gibraltar). This MLR position was defended by elements of the U.S. 2d Infantry Division, on line immediately east of the Marine division, in the sector customarily occupied by the 1st Commonwealth Division. (The Army unit had relieved the British division on 30 January.) A second large-scale assault on the hill that month was also turned back.

[304] Hermes, _Truce Tent_, p. 392.

On 23 March, a Chinese Communist regiment attempted to capture three outposts manned by the U.S. 7th Division, at the far right of the I Corps line. Hills 225 (Pork Chop Hill) and 191 held. The enemy’s main effort was against Hill 266 (Old Baldy), defended by units of the division’s Colombian battalion. One attack carried the position, despite company strength reinforcements of the original defenders. Two strong UN counterattacks the next day to retake the outpost failed, and the Chinese retained the crest of Old Baldy. Although the CCF had gained their objective in Hill 266, the battles on the three hillocks had cost the enemy 750 casualties, according to 7th Division records.

In one respect, the nature and extent of ground operations affected the type of air activity over North and South Korea during the winter of 1952–1953. Introduction of PRESSURE strategy, which had embodied the policy of the Far East Air Forces since mid-1952, brought more aircraft in close support of Eighth Army ground troops, a change that pleased the corps commanders. When the heavy outpost fighting throughout October diminished to only occasional skirmishes in November, there was temporarily a decreased need for large numbers of CAS sorties. As a result more planes became available for PRESSURE attacks. These strikes at first appeared to be reverting to the previous STRANGLE strategy since railroads were often the targets. But interdiction of the transportation system was only part of the PRESSURE aerial concept which also called for striking enemy production, repair, and storage facilities. The Allied strategy in conducting its air offensive remained the same: to make the bombing hurt the Communists so that they would end their deliberate delaying tactics in the truce sessions and join the UNC in effecting a Korean settlement.

During the winter FEAF maintained a steady air pressure against the Communists. Major raids were made from time to time, but the number of strategic targets was gradually disappearing due to repeated UNC air attacks. Further, much of the enemy logistical net had gone so deeply underground during the prolonged stalemate that UN bombing and rocket attacks were having only a limited destructive effect. The U.S. B-29s, which had carried the fight to the enemy since the first week of the Korean conflict, found their last worthwhile objectives in stockpiles hidden in North Korean towns and villages. For the Fifth Air Force fighters there was little opportunity to increase their skill in air-to-air combat, since the Communist fliers continued to take evasive action and avoid “dogfights.”

Naval aviation contributed importantly to UNC air operations from September 1952 to March 1953. On the first day of this period, three carriers staged the largest all-Navy Korean air strike to date, which simultaneously attacked an oil refinery at Aoji and other targets in the northeastern corner of Korea. Less than two weeks later, two carriers launched another assault in the same part of the country. The significance of these September strikes stemmed from the almost complete lack of enemy response. Apparently the Communists in this area had felt secure and protected, their territory being next to the Chinese border. In fact, their location close to the sanctuary had ruled out bombings proposed earlier. Strikes in this part of Korea were particularly suited to carrier planes of the Seventh Fleet, whose mobile airfields brought the targets within easy striking range along approaches that would not violate the Manchurian haven.

Perhaps the greatest naval contribution to the air war were the Cherokee strikes, so named after the commander of the Seventh Fleet, Vice Admiral Joseph J. Clark, because of his Indian ancestry. This new type of deep air support attack, which came into use in October 1952, employed the maxim of mass delivery of ordnance. Usually, targets were immediately behind the enemy MLR but beyond the range of friendly artillery. In May 1952, when the rail interdiction program was being phased out and Admiral Clark’s pilots were faced with a decreasing number of prime industrial targets, the fleet commander had theorized that he could most effectually damage the enemy by bombing supply dumps, artillery positions, and reserve forces immediately to the rear of the Chinese MLR. As the admiral reasoned, the enemy could not fight the kind of war he was waging “and still have _all_ his forces, supplies, and equipment underground. _Some_ of his stocks of supplies had to be above ground, out of sight and out of range of our artillery.”[305]

[305] Quoted in Cagle and Manson, _Sea War, Korea_, p. 461.

Eighth Army welcomed the increased support that would result from the strikes, but FEAF expressed concern about the lack of top-level coordination. Admiral Clark had proposed that a EUSAK corps commander be allowed to authorize the attacks, which employed 24 to 36 aircraft. The Fifth Air Force initially maintained that it should control Cherokee strikes, just as it did the CAS missions. The matter was finally resolved in November.

Following a high-level conference it was decided that attacks inside the bombline would be subjected to FAF coordination and that a minimal amount of tactical control would be exercised by the corps commander. Eighth Army gave a big assist to the Navy by moving the bombline to within 3,000 meters (nearly two miles) of the outpost line. A line was also drawn approximately 25 miles beyond the bombline, separating the area of “general support” from “interdiction.” Thereafter, the Cherokee strikes were effectively conducted against enemy installations outside the 3,000-meter line but within 20,000 meters of the ground front. General Clark, CinCUNC, had high praise for the strikes, which the Seventh Fleet employed until the end of the war.

Surface ships of the fleet were in much the same static warfare situation as the ground and air components of the United Nations Command. Aside from the Kojo demonstration in mid-October, the fleet had little diversification in its daily routine other than to maintain the siege around Wonsan. This operation had started in mid-February 1951 and had grown from the original plan to seize certain strategically-placed islands on both coasts into an attempt to isolate the entire port and city of Wonsan. Each day Allied minesweepers cleared the harbor; at night the enemy sampan fleet resowed the fields. Daily, usually during mine-clearing operations, ships of Task Force 95 fired on batteries in the mountains beyond the city and at other military targets in and around Wonsan. From time to time heavy units of the Seventh Fleet bombarded the area to keep the enemy off-balance and to partially deter the solid buildup of Communist arms and defenses just north of the 39th Parallel.

_Events on the Diplomatic Front_[306]

[306] Unless otherwise noted, the material in this section is derived from: 1stMarDiv ComdD, Dec 52; Berger, _Korea Knot_; Clark, _Danube to Yalu_; Hermes, _Truce Tent_; Robert Leckie, _Conflict--The History of the Korean War, 1950–1953_ (New York: G. P. Putnam’s Sons, 1962), hereafter Leckie, _Conflict_; Rees, _Korea_.

For many of the UNC military personnel, the stalemated combat situation in Korea had become a depressing, no-win daily routine by the end of 1952. Back in the States, the Korean War was not only unpopular and ill-supported, but the slow progress of the conflict had also dulled public interest. In the course of the Presidential election campaign the question of Korea had become increasingly a matter of widespread national concern. Two weeks before election day the Republican candidate, former General of the Army Dwight D. Eisenhower,[307] had vowed to bring the Korean fighting to an end. As a first step toward accomplishing this he had pledged, if elected, to visit the battlefront.

[307] Eisenhower had resigned his commission, following his return to the States in April to seek election.

Some had labeled Eisenhower’s statement, “I will go to Korea” as a mere pre-election gesture. The general intended to act on this pledge and, following his election, began a four-day visit to Korea on 2 December 1952. Part of the President-elect’s brief tour in Korea was spent at General Pollock’s command post. Here, on 3 December, the Marine ground chief briefed his future Commander in Chief on current Marine division operations. Generals Clark, Van Fleet, and Kendall accompanied Eisenhower and his party. This included General of the Army Omar Bradley, Chairman of the Joint Chiefs of Staff, as well as Charles E. Wilson and Herbert Brownell, Jr., the new designates for Secretary of Defense and Attorney General, respectively.

Though General Eisenhower’s promise to visit Korea personally to see the situation first-hand and his subsequent election had renewed American hopes for an early peace in Korea, negotiations there had been deadlocked since 1951 on the exchange of prisoners. Disagreement on this issue thus became the major obstacle which was not overcome until the truce was signed nearly 20 months later. The Communists insisted on repatriation to their native land of all NKPA and CCF prisoners held by the United Nations Command. More than 60,000 of the 132,000 enemy captives held by the UNC in South Korean POW camps did not wish to return to Communism, a fact which had been borne out by a UN survey.

To draw attention from this unpopular position the Communists, through the civil and military links existing in the POW camps, had staged a series of riots in the spring of 1952. The worst, at Koje Island (just off the coast of Pusan) lasted six days, largely because the Communist prisoners planned for, and successfully carried out, the capture of the UN camp commander. His release, on 12 May, was effected only after the new commander signed, under duress, a statement which the Communists immediately exploited in an effort to discredit the validity of the prisoner survey.

The propaganda gains had enabled the Communists to occupy a commanding position at the truce talks. In the meantime, the UN had offered several plans until, on 28 April, Admiral Joy presented “what we called our final package proposal.”[308] By instituting the tactic of calling a recess whenever the Communists had nothing constructive to offer, a recommendation of Admiral Joy’s, the UN regained the advantage of the conference table. The talks continued but with no appreciable progress. On 8 October 1952, after continued Communist intransigence, Brigadier General William K. Harrison, who had become the senior UN delegate in late May, took the initiative in recessing the truce talks. This unexpected action, which caught the enemy off-guard, followed three separate proposals made by Harrison for ending the POW controversy. All had been promptly rejected by the Communist delegation. As General Harrison had informed one of its spokesmen, the North Korean General Nam Il:

[308] Joy, _Truce Negotiations_, p. 156. The proposal was a “complete armistice agreement,” not merely another offer to solve the prisoner question.

We are not terminating the armistice negotiations, we are merely recessing them. We are willing to meet with you at any time that you are ready to accept one of our proposals or to make a constructive proposal of your own, in writing, which could lead to an honorable armistice ... Since you have offered nothing constructive, we stand in recess.[309]

[309] Quoted in Berger, _Korea Knot_, p. 153.

After October, while the truce negotiations were in a period of indefinite recess, liaison officers at Panmunjom kept the channels of communication open between the Communist and UNC sides. Several developments along other diplomatic lines about this time were to prove more fruitful and lead the way to solution of the POW dispute and, in fact, to the end of the war.

In mid-November, an attempt was made to end the prisoner exchange impasse through a resolution introduced by India at the United Nations session. The compromise measure recognized the United States position, namely, that force should not be used in returning prisoners to their homeland. This principle was to become known as the concept of voluntary repatriation.

To reconcile the widely conflicting Communist and UNC views on handling of prisoners, the Indian proposal suggested that a repatriation commission be established. This body was to be composed of representatives of two Communist and two Allied nations. It would function within a designated demilitarized zone in Korea through which all prisoners would be received and processed. Each prisoner was to be given a choice of being returned to his homeland or not. Both sides would have the opportunity of explaining to reluctant nationals “their rights” of repatriation. If these persuasive efforts failed and a man still chose not to return to his country, he would then be referred to a special political conference established by the armistice agreement.

Should this four-member repatriation commission still not agree on settlement of the nonrepatriates, a final determination was then to be made by an official named by the commission or UN General Assembly. Many UNC nations favored the Indian proposal. U.S. official reaction was frankly skeptical and critical, well aware that the many vague aspects of the proposal could easily be exploited by the Communists to the disadvantage of the individual POW. Despite the promise of a good many headaches in its implementation, the UN adopted the compromise Indian resolution in December 1952 by a vote of 54 to 5.

Later that same month the Executive Committee of the League of Red Cross Societies, meeting in Geneva, adopted another feature of the Indian resolution proposing an exchange of sick and wounded POWs in advance of a truce. As General Clark observed, “It was hardly an auspicious omen for an armistice, yet it was the action which set in motion a chain of events which finally resulted in cease-fire.”[310]

[310] Clark, _Danube to Yalu_, p. 240.

On another front, State Department officials advised the Joint Chiefs of Staff that a resolution similar to that of the Red Cross would probably be introduced when the UN reconvened on 24 February. Following a JCS suggestion that a “feeler” proposition be first made to the Communists, General Clark wrote the NKPA and CCF leaders on 22 February. His letter was addressed to North Korean Premier Kim Il Sung and General Peng Teh-huai, the CCF military commander. Delivered through the Panmunjom liaison officers, it requested the immediate exchange of sick and wounded POWs. As both diplomatic and military leaders doubtfully awaited the results, a totally unexpected and far-reaching event, the death of the Russian leader, Premier Joseph Stalin, jolted the Communist world. Its repercussions soon extended to the truce tent at Panmunjom and decisively affected the progress of negotiations there.

_The Marine Commands During the Third Winter_[311]

[311] Unless otherwise noted, the material in this section is derived from: 1stMarDiv ComdDs, Nov 52-Jan 53; 1stMar ComdDs, Nov 52-Feb 53; 5thMar ComdD, Dec 52; 7thMar ComdDs, Nov 52, Jan 53; 11th Mar ComdDs, Jan-Feb 53; 2/1 ComdD, Nov 52; 1st MAW ComdD, Jan 53; MAG-12 ComdD, Jan 53; MAG-33 ComdD, Oct 52; MACG-2 ComdD, Feb 53.

Although renewed negotiations to bring the war to a close were under way with the enemy in late 1952 and early 1953, action on the battlefield continued the tedious routine of the war. An exception to the general lethargy across the front occurred on 22 November in the right regimental sector. A predawn raid was conducted by the 1st Marines, which had advanced to the front upon relief of the 7th Marines after their battle of the Hook. With the left and right battalion sectors manned by 1/1 and 3/1, respectively, Lieutenant Colonel Charles E. Warren’s 2/1, in regimental reserve, had been ordered to provide a company to raid Chinese positions across from COPs Reno and Vegas. Drawing the assignment was Company D (Captain Jay V. Poage).

Code-named WAKEUP, the raid was conducted in a manner typical of many earlier forays against Chinese strongpoints. Its results, too, in most respects were similar to the outcome of previous raids. Artillery preparation of the objective area was accomplished, the infantry assaults were somewhat short of the targets due to heavy CCF defensive fires, and the prisoner-taking part of the mission was unfulfilled. Counterbalancing this, and what made the raid of value to the regiment, was the information gained about enemy defenses and Chinese reaction to the raid. It was one of the rare occasions during which the CCF did not employ artillery fire while their positions were under attack, using instead mortars and automatic weapons against Marine assault forces.

Raids such as WAKEUP, patrols, and ambushes became the pattern of action in late November and in December. Earlier in November some changes in the MLR dispositions had taken place. On 3 November, at 2345, the 1st Battalion of the Black Watch, 29th Infantry Brigade, 1st Commonwealth Division, had relieved 1/7 of the Hook sector responsibility, ending Marine occupation of that part of JAMESTOWN.[312] And, on 16 November, the 7th Marines itself had been replaced in line by the 1st Marines. In between these changes of command on the frontlines, Generals Pollock and Jerome had received many congratulations and well wishes from combat commands and from government officials in the States. The occasion was the 177th birthday of the Marine Corps. Both of these senior commanders passed on to their Marines not only the Commandant’s Anniversary message but also the congratulations of the UNC commander, General Clark.

[312] At this time a new limiting point between the division and British division was also established. This slightly reduced Marine division frontage to 33 miles and allowed the two MLR regiments to shorten their lines and maintain somewhat larger reserve units. _PacFlt EvalRpt_ No. 5, Chap. 8, p. 8-23.

Though the Commonwealth division had taken over the Hook area from the infantry Marines, the division’s participation in defense of the British sector had not completely ended. On 18–19 November, the 11th Marines expended more than 2,000 rounds to repel Chinese attacks on the Hook. This firing by the artillery regiment helped to repay the British for their “cooperation and outstanding artillery and tank support during the engagements of 26–28 October....”[313] And as the Commonwealth division commander, Major General M. M. Austin-Roberts-West, had himself reported to General Pollock the day following the Hook attack, “All hands on the Hook much appreciated the prompt and effective support given last night. Grateful if you would pass on their thanks to all concerned.”[314]

Throughout December 1952 and January 1953, the lull in ground fighting continued. Mass Cherokee strikes by Admiral Clark’s Navy and Marine fliers had begun for the Marine division on 17 December, when the bombline was moved in nearer to the MLR for expanded operations. In noncombat activities, later that month Francis Cardinal Spellman, Archbishop of New York and Vicar for Catholic Chaplains of the Armed Forces, conducted a Christmas Mass at the division CP. On the 31st, His Eminence visited the 1st MAW at K-3 (Pohang). There he delivered an address to about 1,000 Marines, shook hands with nearly all of them, and later heard confessions for many. Another special guest, not long afterward, was Episcopal Bishop Austin Pardue, of the Pittsburgh Diocese, who held Holy Communion at the division chapel.

The passing of 1952 and the arrival of the new year was not marked by any special observance on the battlefield. For that matter there was, it seemed, no change to note; the Marines, like the rest of the Eighth Army troops, maintained much the same regular, reduced, wintertime schedule. Activity of Marine infantry units consisted of aggressive patrolling and raids, and improvement of the secondary defenses of Lines WYOMING and KANSAS. Units in division reserve, during January, also participated in MARLEX (Marine Landing Exercise) operations.

No major ground action had taken place in December, although Marine patrols, on a half dozen occasions, had engaged as many as 50 enemy for brief clashes and fire fights. January was a different story, however. On 8 January, a 7th Marines raiding party, reinforced by air, artillery, and tank support, skirmished with 85 Chinese in the Hill 134 area not far from COP 2, overlooking Panmunjom. Ten days later, the 1st and 7th Marines, together with the artillery regiment, took part in Operation BIMBO. This was another attempt, by combined infantry-artillery-tank-air action, to create the impression that CCF objective areas were under attack.

BIMBO began with heavy preparatory fires by the 11th Marines, including the 155mm projectiles hurled by 4/11, that inflicted early damage to CCF personnel and materiel. At 0630, on 18 January, frontline battalions of the two participating infantry regiments opened fire; reserve battalions assisted with indirect machine gun fire. Armored vehicles added to the effect of the ruse by shelling Chinese emplacements from prepared MLR positions. Marine attack planes streaked in to unload flaming napalm. In response to the BIMBO mock attack, the Chinese directed mortar fire into suspected Marine avenues of approach and assembly areas. Forward observers on JAMESTOWN could detect some enemy troop movement. (Marine artillery took these formations under intensive fire), but as in similar feint operations in the past, the enemy again failed to pick up the bait. The operation lasted approximately an hour and a half.

During the winter months, a number of command changes had occurred in the Marines’ combat organizations in Korea. In the 1st Marine Aircraft Wing, the rotation of commanders began at the very top when, on 8 January, General Jerome handed over the wing colors to Major General Vernon E. Megee. During a ceremony at wing headquarters that day, Air Force Generals Weyland and Barcus paid tribute to General Jerome’s “exceptionally meritorious service” as 1st MAW CG since April 1952 by presenting him with the Distinguished Service Medal.

The incoming wing commander, General Megee, had been a Marine flyer for 20 years, having received his wings in 1932. His Marine Corps career began more than a decade earlier, with enlistment in 1919. Commissioned in 1922, he served in infantry, artillery, and expeditionary billets before undergoing pilot training in 1931. Following school, staff, and command assignments, Major Megee was named advisor to the Peruvian Minister of Aviation from 1940–1943. During World War II, Colonel Megee was sent overseas as 3d MAW Chief of Staff in early 1944. As Commander, Control Unit One, he participated in the Iwo Jima campaign, earning the Legion of Merit. Later, at Okinawa, he commanded all Marine Corps Landing Force Air Support Control Units. After promotion to brigadier general in 1949, General Megee was named Chief of Staff, FMFLant. Receiving his second star in 1951, he served as Commanding General at Cherry Point, El Toro, and Air FMFPac prior to his assignment in Korea.[315]

_1st MAW Operations 1952–1953_[316]

[316] Unless otherwise noted, the material in this section is derived from: _PacFlt Eval Rpts_ No. 5, Chap. 9 and No. 6, Chap. 10; 1stMarDiv ComdD, Nov 52; 1st MAW ComdDs, Oct 52, Jan-Feb 53; MAG-12 ComdDs, Nov 52, Jan 53, Mar 53; MAG-33 ComdDs, Nov 52, Jan-Mar 53; VMA-121 ComdDs, Nov-Dec 52, VMF-115 ComdDs, Nov-Dec 52; VMF(N)-513 ComdDs, Oct 52-Jan 53; HMR-161 ComdDs, Jul 52, Nov-Dec 52, Jan 53; Futrell, _USAF, Korea_; Montross, _SkyCav_.

The heavy ground fighting across the Eighth Army front in October 1952 had drawn heavily upon units of the 1st MAW. That month Marine pilots logged their greatest number of sorties--3,897--since June 1951.[317] As a result of the intense infantry action in the 1st Marine Division sector another air record was established--365 casualty evacuations by HMR-161 during October. This was a peak number to that time for the helicopter transport squadron for which med evac was a secondary mission. These “mercy missions” were not limited only to wounded Marine infantrymen or downed aviators.

[317] A total of 1,362 CAS sorties were flown, with 443 for the 1st Marine Division. Interdiction missions numbered 1,842, plus additional miscellaneous and air reconnaissance flights. 1st MAW ComdD, Oct. 52.

Whenever and wherever immediate air rescue was needed, the choppers were sent. In July 1952, HMR-161 evacuated “650 Army and Air Force troops as well as 150 Koreans”[318] from a flooded river island. On the night of 18 January 1953, a helicopter retrieved five Marines from an uncharted minefield after one of the group had accidentally stepped on a mine. On 13 March, HMR-161 sent three helicopters aloft in an attempt to save five men from the 1st Amphibian Tractor Battalion who had become trapped in mud near the edge of the Imjin, and later that month the squadron dispatched a chopper to rescue a hunter marooned in the middle of the Han River.

[318] Montross, _SkyCav_, p. 189.

Almost obscured in the magnificent record of the mercy missions, especially the hazardous casualty evacuations by the VMO-6 pilots, were the problems encountered by the observation and helicopter squadrons. Under operational control of the division and administrative control of the wing, the squadrons found themselves exposed to overlapping command authority which sometimes resulted in conflicting directives from higher headquarters. Some squadron personnel felt that establishment of a helicopter group under the 1st MAW might have solved many of the organizational problems, but such a unit was never established in Korea, partly because only one helicopter squadron (plus half of the observation squadron) existed.

Another organizational difficulty beset VMO-6. With two types of aircraft and two unrelated missions (med evac for the HTL and HO5S copters; observation and artillery spotting for its little OYs and, later, OE-1s), the squadron found supply and maintenance problems doubled and operational control of its rotary and fixed wing sections extremely complex. Attachment of the VMO-6 choppers (for evacuation, administrative, and liaison missions) to HMR-161 was suggested as a possible solution to these difficulties, but was never done.

Other problem areas became apparent during the winter of 1952–1953. Accompanying the freezing weather were difficulties in starting and, for a brief time, in flying the helicopters. In order to overcome the engine starting problem on emergency evacuation missions, HMR-161 preheated its number one standby aircraft every two hours during the extreme cold. Dilution of engine oil with gasoline and use of warming huts (the latter, a scarcity) were also employed to cut down cold weather starting time.

Not related to freezing Korean temperatures were two additional problems, one navigational and the other mechanical. In January, the helicopter squadron put into use a jeep-mounted homing device for operations in reduced visibility. It proved unsatisfactory due to interference from other radio transmitters in the area, a difficulty never resolved during the rest of the war. The mechanical problem lay with the rotary winged aircraft in HMR-161. On 27 March, all of its HRS-2 choppers with more than 200 hours on the main rotor blades were grounded. Discovery in the States that minute .002-inch cuts on the blade surface had occurred during fabrication resulted in the grounding. New blades were promptly flown to Korea from both Japan and the United States, and the squadron again became fully operational on 2 April.

Evaluation of transport helicopter techniques continued during the period despite ever-present minor difficulties. At least one new HMR-161 tactical maneuver was scheduled each month to evaluate existing procedures and determine full operational capabilities of the aircraft. During these landing exercises both the infantry and helicopter commanders and their staffs had the opportunity to further develop vertical envelopment techniques that would soon be the new trademark of U.S. Marine Corps operations.

Most of the time HMR-161 operations drew more attention than those of VMO-6, but pilots in the latter unit had a host of division Marines who could attest to the skills and critical role performed by helicopter fliers in the composite observation squadron. VMO-6 had pioneered the night casualty evacuation service, and during the active fighting in Korea, had flown out more than 1,000 Marines from frontline medical facilities to better-equipped ones in the rear areas. These flights were made in all kinds of weather and without the benefit of adequate instrumentation or a homing device. No other Eighth Army helicopter unit made regularly scheduled night frontline evacuations.[319]

[319] A relatively small number of night med evac flights was also being flown by HMR-161. During March 1953, for example, in transferring 283 casualties to the hospital ships, squadron helicopters made only 15 flights at night.

The courage of these VMO-6 pilots was recalled nearly 15 years later by a former executive officer of the 1st Marines:

The flying of the evacuation helicopters from the jury-rigged and inadequate landing sites was nothing short of miraculous. I’ve always contended those pilots of the observation squadron received far less credit than they deserved. They used to fly at night, to frontline landing strips, where I had difficulty walking without barking my shins.[320]

During the latter part of 1952 and the first months of 1953, 1st Marine Aircraft Wing command relationships underwent a significant change. On 26 January 1953, General Megee forwarded a memorandum request to General Barcus. The paper outlined specific recommendations for restoring 1st MAW tactical elements to wing operational control, even though the Marine wing would continue as a tactical component of Fifth Air Force. In the proposal, CG, 1st MAW pointed out (as had his predecessors) that the existing command structure, in effect, completely bypassed the Marine wing commander. It had prevented him from exercising normal tactical command functions, even though he was fully responsible for the performance of his air groups and squadrons to FEAF/FAF orders. The 1st MAW commander’s proposal was intended to counter previous Air Force objections and demonstrate that more normal command relations would “enhance, rather than reduce [1st MAW] operational efficiency and effectiveness.”[321]

[321] _PacFlt EvalRpt_ No. 6, p. 10-76.

At the same time, having been informally advised in an earlier conversation that CG, FAF would approve at least some of the requests made, General Megee implemented changes in his G-2 and G-3 staff sections. This reorganization was aimed at carrying out the increased functions which would result from approval of the request. Operational control of Marine tactical squadrons by FAF since 1951 had “relegated 1st MAW to the status of an administrative headquarters, forcing its G-2 and G-3 sections partially to atrophy.”[322] To effect the changes in command relationships and establish the wing on an operational basis, the G-2 and G-3 sections were expanded. By the nature of their organization these were not capable of either targeting or tactical planning. In the intelligence section, a Target Information Sub-section was established to compile data on the mission targets (and accompanying photographs) received from FAF and to evaluate the desired objectives.

[322] _Ibid._

Upon receipt of this information, the G-3 planning group accomplished the target solution, prepared general tactics for conducting the strike, (number of planes, amount and kind of ordnance, approach routes to be used) and provided post-strike target evaluation. The chiefs of these sections jointly presented the completed information to the wing commander each afternoon. He selected the targets and forwarded via teletype and air courier to the wing G-3 representative at FAF headquarters a report of intended operations, providing a lead time of 36–48 hours.

As soon as the OP INTENT (Operations Intentions Report) was on its way to General Barcus for approval, the 1st MAW intelligence section began to prepare the target dossiers (including photographs, flak analysis, and related identification information) on each of the approved targets. The compiled dossiers were then sent to the appropriate tactical squadron. At this point, still perhaps a half-day before issuance of the FAF orders, the squadrons received two major advantages over the previous system:

(1) Adequate photo intelligence employed for the first time since FAF had assumed operational control of 1st MAW; and

(2) A substantial lead time advantage for proper briefing of pilots and arming of aircraft.

After the strike, and usually within an hour, Marine planes photographed the targets for damage assessment. These photos were annotated and an assessment report prepared. This information was then presented by the G-2 and G-3 to the wing commander. Immediately thereafter, prints of the photographs were distributed to the appropriate tactical units, thus making post-strike photography more freely available on a regular basis to the participating tactical units.

In a letter dated 18 February, General Barcus approved most of the 1st MAW commander’s specific requests, but retained full control over General Megee’s squadrons used in close air support. This was due to the fact that EUSAK-FAF joint policy required CAS mission requests to be approved by JOC, in accordance with daily Eighth Army priorities, which allocated the aircraft for each request. Returned to operational control of the Marine wing were planes used on interdiction, armed reconnaissance and general support activities--the planes on strikes beyond the bombline, the photo, and all-weather (night) squadrons. FAF also retained control over assignment of missions to VMC-1, the electronics unit.

Although some of the Marine wing tactical squadrons thus newly enjoyed the advantages of flying under their own commander’s wings, 1st MAW headquarters staff members had to pay for these benefits. An increased work load swamped the G-2 section, where 7 photo interpreters were kept busy 16 hours a day, 7 days a week. Marine personnel processed and reviewed an average of 100,000 prints per month and these were “only those from that portion of the VMJ-1 effort devoted to 1st MAW operations.”[323] Expansion of 1st MAW headquarters to set up a tactical planning capability pointed to a deficiency in the wing organization T/O, a weakness that existed during the rest of the war.

[323] _Ibid._, p. 10-80.

While General Barcus earlier had General Megee’s recommendations under study, a radio news broadcast back in the States momentarily resulted in poor publicity for the Marine Corps. On 1 February a nationally syndicated columnist reported instances in which friendly troops had been bombed and strafed by U.S. aircraft. Marine Corps planes were the most careless, the broadcaster alleged, basing his statement on incomplete information. The news story had developed from an unfortunate publicity release issued by FEAF dealing with a MAG-33 incident. The phrasing implied that Marine aviators were “guilty of gross carelessness resulting in casualties among their own ground troops.”[324]

[324] _PacFlt EvalRpt_ No. 5, p. 9-81.

Actually, of the 63 incidents in which friendly casualties had resulted from aircraft flown by FAF units between January and October 1952, 1st MAW pilots were responsible for 18, or 28.5 percent of the total number of incidents and majority of casualties. What was left unsaid, however, in the unfavorable publicity was that with approximately 14.5 percent of the aircraft represented in FEAF, Marine fliers had been accomplishing monthly totals of between 30 to 40 percent of all Eighth Army CAS missions. They also performed virtually all of the very close air support jobs (50 to 100 yards out from the MLR) which further reduced the comparative percentage of Marine “carelessness.”

It was true, of course, that on rare occasions freak accidents did kill and injure UN troops, despite the continual training of pilots and controllers in strike procedures and target identification. The position taken by the two senior Marine commanders in Korea was that although any CAS incident involving friendly troops was highly regrettable, it was in the same category as “short” mortar and artillery rounds and just as unavoidable.

Target identification, low visibility flying conditions, and ballistic computations made the task of precision close air support an enormous one. If anything, it was almost a wonder that more accidents did not happen. Despite the similarity of Korean geography, an unending panorama of almost identical hilltops, ridges, and streams, the pilot had to release ordnance at the proper altitude and speed, and in a balanced (trim) flight. While conducting his dive the pilot’s view could be blocked by cloud formations and his attention distracted by antiaircraft fire which required evasive action. Even when the ordnance had been properly released, prevailing wind conditions could affect the flight path of the bombs. This, in addition to human error and mechanical factors, such as the occasional malfunctioning of parts, also affected the accuracy of bombing.

Throughout the November 1952-March 1953 period, 1st MAW squadrons continued to provide the bulk of close air sorties to the 1st Marine Division, in keeping with General Barcus’ policy stated earlier in 1952. Between November and January there had been a lull in the heavy ground fighting that had prevailed in October and little need to request air strikes. When enemy forces opposing the division began to grow more active in February, however, the requirement for air support to 1st MarDiv greatly increased. During this month 1st MAW aviators reached an all-time high in the percentage of their total CAS sorties devoted to the division--two of every three wing close support sorties went to General Pollock’s infantry regiments.

On the critical issue of close air support, the Marine division had become better satisfied by the end of 1952 with the quantity of air support received from FAF. A continuing difficulty, however, was the delayed response to requests for immediate CAS. For the wing, several other conditions existed which bothered General Megee. One was that the VMA-312 carrier-based squadron was not utilized to any great extent in execution of CAS missions. This detrimental condition saddled the wing commander with an “unqualified” squadron. It also prevented pilots from practicing a highly developed skill they were responsible for maintaining, although later in the war this condition was gradually alleviated. Two other difficulties--centralized control of CAS mission assignments by JOC and the prevailing differences between the Marine and Air Force/Army CAS communications systems and request procedures--were never rectified.[325]

[325] _PacFlt EvalRpt_ No. 6, p. 10-80.

One long-standing difficulty, though not a CAS matter, had been solved early in the winter. Following a series of mechanical troubles with the F3D-2 aircraft in VMF(N)-513 and prolonged delay in receipt of blast tube extensions for its 20mm guns, the squadron finally became fully operational on 1 November with its complement of 12 of the new jet Skyknight aircraft. Almost as soon as the F3D-2s were ready for night work, FEAF had put them to escorting B-29s on bombing runs over North Korea. With the F3D escort and changes in B-29 tactics, bomber losses, which had been severe, decreased sharply. Enemy attackers became fewer and fewer so that by February, air-to-air opposition was encountered only infrequently. Instead of sending up groups of night fighters at the escorted B-29s, the enemy would fly a single jet across the bomber formation. If a Skyknight followed, one or two MIG-15s, well to the rear and higher than the decoy, would attempt to gun down the Skyknight in its pursuit. But because of the F3D tail warning radar, the Marine radar operator could detect the enemy plane in its approach for the kill before it got within effective firing range.

Lieutenant Colonel Hutchinson’s VMF(N)-513 pilots soon established an enviable record for Marine aviation, netting by 31 January five enemy jets without loss of a single F3D. In addition to the jets, the squadron downed a piston engine plane and scored a probable destruct on another. During its first three months of operations with the Douglas Skyknights--the first Navy-Marine jet night-fighter to arrive in the Korean combat theater--the squadron earned two night-kill records. It also quickly proved the design theory and proposed tactics for the Skyknights that enemy aircraft could be located, intercepted, and destroyed purely by electronic means.

While on a night combat air patrol in the vicinity of Sinuiju airfield early on 3 November, Master Sergeant H. C. Hoglind picked up a contact on his intercept radar, which a ground radar station had passed on to him, and notified the pilot, Major William T. Stratton, Jr. After losing and reestablishing radar contact, Major Stratton made a visual sighting of a jet exhaust straight ahead. When he had been cleared to proceed, the Flying Nightmare’s pilot sent three bursts of 20mm into the other plane, identified as a YAK-15. Three explosions followed and the aircraft plunged towards the airfield directly below. This marked the first time that an enemy jet had been destroyed at night by use of airborne intercept radar equipment in a jet fighter.

Five days later the team of Captain Oliver R. Davis and Warrant Officer Dramus F. Fessler bagged the first MIG-15 for the squadron. Captain Davis expended only 20 rounds of 20mm cannon fire in his aerial victory, which took place northwest of Pyongyang near the Yellow Sea.

The next two months brought new distinction to Marines in -513. Shortly after dark on 10 December, First Lieutenant Joseph A. Corvi had departed on a night combat patrol mission. About 35 miles northwest of Chinnampo, his radar operator, Master Sergeant D. R. George, picked up a target on his scope. Since the “bogey” (an unidentified aircraft, believed to be hostile) was three miles distant, the pilot quickly closed on the contact and shot it down. Almost immediately another blip appeared on the radar screen. Lieutenant Corvi turned to the new attack and began approaching it, but because of the slower speed of the enemy plane the Marine pilot was able to fire only one short burst before overtaking it. An instant before passing the enemy aircraft, Lieutenant Corvi saw it disappear from the radar screen, but neither member of the Flying Nightmares crew had made a visual sighting with the plane itself, listed as a probable kill. What these two Marines had accomplished with their earlier encounter was the first attempt to destroy an enemy aircraft without use of a visual sighting by means of lock-on radar gear.

All-weather squadron crews continued to demonstrate the F3D-2 capability for destruction of hostile aircraft by electronic intercept during January. The first MIG-15 downed was by Major Elswin P. (Jack) Dunn and Master Sergeant Lawrence J. Fortin, his radar operator. On 28 January Captain James R. Weaver and Master Sergeant Robert P. Becker destroyed another of the Russian fighter-interceptors in an aerial duel. The final kill came on the 31st when the new squadron commander, Lieutenant Colonel Robert F. Conley (who had taken over VMF(N)-513 on the 20th) accompanied by Master Sergeant James M. Scott bagged the Marine fighter pilots’ 12th MIG of the war.

While VMF(N)-513 wrote several records in the sky, other MAG-33 and -12 squadrons also made their contribution during the winter of 1952–1953. In MAG-12, a highly successful noontime strike was launched on 16 November by 21 attack planes from VMAs-121 and -212 against a hydroelectric plant 25 miles southeast of Wonsan. For this exploit the group received the plaudits of the Fifth Air Force CG, General Barcus. Lieutenant Colonel John B. Maas, Jr.’s VMF-115 (he had succeeded Lieutenant Colonel Coin as CO on 29 September) helped all Marines celebrate their 177th birthday by sending 22 Panthers against enemy troops and supply shelters. On these strikes each MAG-33 aircraft was armed with 760 rounds of 20mm and 4 napalm tanks (500 pounds each), the first time that 4 tanks that large had been dropped from a fighter-bomber. This was part of the 98 sorties flown by 1st MAW against 21 enemy targets on the 10 November anniversary date. During December 1952, the frequency of combat flights by VMF-115 enabled the squadron to surpass its old (August 1951) monthly sortie record. The Panther jet fliers set this new mark of 726 effective sorties in the last 31 days of the year.

More honors came to wing pilots in the new year. On 8 January, three MAG-12 squadrons flew more than 28 combat sorties. Some, in support of the 1st Marine Division near the Panmunjom corridor, by VMAs-121, -212, and -323, produced outstanding results, earning the praise of General Pollock. Among the participating pilots was Lieutenant Colonel Barnett Robinson (VMA-212), who a week earlier had taken command of the squadron from Lieutenant Colonel Dobson.

Between 9–14 January, MAG-33 participated in a USAF-USMC joint operation to strike the rail system at Sinanju, 45 miles north of the enemy capital, and at Yongmi-dong, to the northwest across both the Chongchon and Taedong Rivers. During the six-day Operation PARALYSIS, Marine and Air Force jet squadrons flew flak suppression and interdiction missions, knocking out ground-based air defense weapons and damaging and destroying bridges, rails, and rolling stock. At night FEAF Bomber Command, with Flying Nightmare escorts, worked over the communications net, including repair facilities; during daylight, the fighter-bombers attacked marshalling yards near Sinanju, where railroad cars were stacked up awaiting repair of the river bridges. Bomb assessments and intelligence reports showed that two major rail lines were inoperative for 16 days and that, as General Barcus had predicted, the Chinese “hurriedly increased their antiaircraft defenses in the Chongchon estuary and shot down seven fighter-bombers.”[326]

[326] Futrell, _USAF, Korea_, p. 582.

Following this operation, Colonel Robertshaw’s jets from VMFs-115 and -311 achieved extremely effective close air support in strikes flown 24 January in the I Corps area. About a month later, with an F9F as an airborne command post and with Lieutenant Colonel Walt Bartosh on his wing, the MAG-33 commander directed the operations of 208 USAF and Marine aircraft on another mass strike. The two-day mission was flown on 18–19 February against the North Korean tank and infantry school southwest of Pyongyang. More than 240 buildings were destroyed in 379 sorties. The attack was one of the largest all-jet fighter-bomber strikes of the war. Colonel Robertshaw thereby became the first Marine to lead such a large joint air-strike force from a CP aloft. And the next month, on 8 March, the Group CO flew the first Marine jet night MPQ mission, dropping six 250-pound bombs from an F9F-2 Panther on an enemy ammunition dump.

_Behind the Lines_[327]

[327] Unless otherwise noted, the material in this section is derived from: _PacFlt EvalRpts_ No. 5, Chaps. 8, 9, No. 6, Chaps. 9, 10; 1stMarDiv ComdDs. Jan-Feb 53; 1/1 ComdD, Feb 53; HMR-161 ComdD, Feb 53; Montross, _SkyCav_.

The Marine aviation command, like the division, found that its commitment to a large-scale land campaign in Korea considerably increased its requirements for nonorganic support, compared with normal amphibious combat operations. The wing fell heir to more of the permanent problems because its organization was less suited to the heavy support requirements of prolonged combat. Whereas the 1st Marine Division received adequate support through the FMFPac Service Command, the wing did not since the service command had been tailored more for support of ground organizations. Moreover, the command relations established in Korea underscored this situation, with the 1st Combat Service Group placed under CG, 1st Marine Division. The wing received emergency logistical support from VMR (Marine transport squadron) units. This was not an adequate substitute for the various ground support agencies essential for employment of the wing’s full combat potential.

Major problems pertaining to service and support functions of 1st MAW units resulted from the use of amphibious Tables of Organization throughout the period of prolonged land combat without making a T/O adjustment for the actual combat mission being performed. What the wing had recommended to solve its longstanding support and supply problems was either to strengthen its organic logistical structure or to increase it by the attachment of appropriate units. It was emphasized that “prolonged Wing operations under Air Force control with logistical support derived from four different services, each at the end of its supply pipeline, brought clearly into focus the requirement for centralized control and monitoring of Wing requisitions and supplies.”[328]

[328] _PacFlt EvalRpt_ No. 6, p. 10-133.

A step toward expanding the amphibious T/O of the wing was made in 1953 with the request from CG, 1st MAW to CG, FMFPac for a detachment of the 1st Combat Service Group to provide electronics logistical support. It was further recommended that the electronics section be made organic to the wing to meet its need for this type of service unit.

Unlike the division, existing T/Os made it impossible for the wing to consolidate and control resupply requests from subordinate units and then to monitor the requisitions until parts or supplies were received by the users. This lack of a central wing supply agency had, for some time, impaired the effective, sustained performance of 1st MAW ground electronics equipment in Korea. CG, FMFPac concurred with the proposal. He requested an increase in the wing T/O of four additional electronics supply personnel to be attached to the wing for this purpose. The basic problem of establishment of a combat service group tailored to fully meet 1st MAW needs in the field remained unresolved, however.

Supply problems in the division were less complicated. On 11 November 1952, General Pollock submitted a letter to the theater commander requesting approval of a special list of equipment in excess of certain Tables of Organization and Equipment within the division. The requirements of the Marine land war mission in Korea dictated the need for additional equipment, primarily crew-served weapons and automatic rifles. Approval was given on 19 January 1953 by CG, AFFE (Army Forces, Far East). All equipment received through this program was to be returned upon the departure of the Marine division from Korea.

During the cold months that ended in March 1953, the division continued its evaluation of experimental clothing and equipment. Items of winter wear generally proved to be highly satisfactory. The thermal boot, in particular, gave excellent service. On the other hand, the leather combat boot did not fully measure up to expectations. Most of its deficiencies were caused by the rapid wearing of the composition sole. One clothing item, the armored vest, had undergone further testing. In November, delivery of the vests to the division had been completed, including 400 sets of the new lower torso armor. Recent issue of this additional type of body armor appeared highly effective in reducing combat casualties; its extended coverage also raised morale.

Though their ability to halt successfully a Chinese bullet or exploding shell was being improved on, thanks to armored wear, the Marines’ opportunity to keep the enemy from division outposts or MLR areas was still being hampered by occasional ammunition shortages. From time to time during the winter months there was some relief from the grenade and howitzer firing restrictions that had been in effect before the Hook fighting. The cutback on use of 81mm mortar shells continued, however, as the supply level of these projectiles remained dangerously low.

A new shortage, this one in fuel, developed during the winter. In January 1953 it became necessary to reduce the distribution of gasoline for motor vehicles to .829 gallons per man per day, a drop of 17 percent from the previous month’s allocation. Diesel fuel was cut back to 1.41 gallons, or 7 percent less than the December ration. By February, however, the crisis had passed and vehicles returned to a less restricted operating schedule. No extreme hardship had been experienced by the Marines during the fuel drought. It was considered that “prolonged operation under such restrictions would result in a marked decrease in efficiency since many essential activities may be temporarily postponed, although not entirely eliminated.”[329]

[329] 1stMarDiv ComdD, Jan 53, p. 3.

The month of February also witnessed the largest helicopter supply lift in Korea, HAYLIFT I, the previous September, had tested the feasibility of transporting Class I, III, and V supplies to a frontline infantry regiment for five consecutive days. HMR-161 and the 7th Marines had turned out an excellent test performance of the rotary craft in this logistical operation. It then became the task for the infantry and helicopters to run a resupply operation for two frontline regiments for a five-day period. HAYLIFT II, conducted 23–27 February, was the code name for this test.

Both the planning and execution of the February operation followed the general pattern of HAYLIFT I, but on a much larger scale. As in September, division ordnance and service battalions moved the supplies to helicopter loading zones near Lieutenant Colonel Carey’s HMR-161 air strip. It had been estimated that 130 tons each day would have to be lifted to supply the two MLR regiments, the 7th and 5th Marines. On the first day, this figure was exceeded by 30 tons. A request by A/1/5 on 24 February for support during an emergency operation necessitated additional ammunition[330] and helicopters to be diverted from those resupplying the 7th Marines. By the third day, a backlog of supplies had accumulated in the loading areas. In order to eliminate this buildup and to replace ammunition expended that morning by 1/5, HMR-161 on 25 February transported 200 tons in a single day, thereby establishing a new record. This represented 392 lifts made in 138.4 hours flying time. Maximum time for unloading a chopper was 54 seconds; the minimum, 28 seconds.

[330] The following month, HMR-161 engaged in a four-day ammunition resupply operation for the division. Except for one day, the 22d, all available helicopters were assigned to that mission, beginning 20 March. HMR-161 also had a new CO by that time, Colonel Owen A. Chambers who had taken over from Lieutenant Colonel Carey on 15 March.

The last two days of HAYLIFT II, although less eventful, contributed to a resupply tonnage record five times greater than that set by HAYLIFT I. On the last day, when fog grounded their aircraft for a second time during the morning, Marines were again reminded of an operational limitation of the helicopters. In the end, though, the accomplishments far out-weighed this shortcoming. During the five days, a total of 1,612,406 pounds of supplies had been lifted to the two frontline regiments. Not one crewman or helicopter was lost. The operation contributed significantly to the February record for the greatest number of combat hours (765), total hours (1,275.5), combat flights (575), and total flights (1,183) flown by HMR-161 for any one-month period during the Korean fighting. For the rest of the war, the February 1953 gross lift of 2,018,120 pounds would also rank as the largest amount transported by HMR-161 for a single month.

_The Quiet Sectors_[331]

[331] Unless otherwise noted, the material in this section is derived from: KPR ComdDs, Jun, Aug, Oct-Dec 52, Jan-Mar 53; 1st AmTracBn ComdDs, Mar-Dec 52, Jan-Mar 53.

Two frontline units in the division MLR seldom became involved in setting records or bitter contests with the enemy, even though they carried out important roles in the sector defense. These were the Kimpo Provisional Regiment and 1st Amphibian Tractor Battalion, both located on the left flank of the Marine line. The Kimpo Provisional Regiment had been organized as a component of the 1st Marine Division a week after its arrival in the west, specifically for defending that vital sector at the extreme left of the UNC line. The next month the 1st Amphibian Tractor Battalion had been assigned part of Line KANSAS between the KPR and KMC sectors.

Because it was set apart from the Korean mainland on the north and east by the Han River,[332] Kimpo Peninsula afforded little opportunity for its occupants to engage the enemy directly in infantry clashes. Artillery thus became the normal medium for carrying on the limited hostilities as they existed in this sector between the Communists and UNC opponents. Hostile forces opposing the KPR were deployed in company-sized strongpoints across the river, occupying numerous fortified heights on the north bank of the Han estuary. Enemy strength[333] was estimated to be 7 infantry companies, supported by 7 artillery batteries and 40 mortar positions. Sporadic mortar and artillery rounds fell in the sector, with little harm. Occasionally, enemy counterbattery fire caused minor damage to the LVTs of the command. During 1952, the first year of the existence of the Kimpo regiment, 15 June had stood as the record day for the number of enemy artillery rounds received. Between 1900–2100 a total of 588 shells had fallen in the sector.

[332] On the west, the Yom River similarly separates the Kimpo Peninsula from Kanghwa-do Island, second in size of all Korean islands and a base for friendly intelligence operations.

[333] Identified as elements of the 195th CCF Division of the 65th CCF Army and an unidentified CCF division, in a revised EOOB issued in December. Previously, units of the 193d CCF Division were at the front in this far western sector. KPR ComdDs, Oct-Dec 52.

As part of its normal defense mission, personnel of the regiment spent a large part of their time controlling civilians and regulating traffic, especially water travel. Certain counterintelligence problems confronted the Kimpo Provisional Regiment. A large civilian population, numbering nearly 80,000 natives, lived within the regimental sector. Local restrictions set by the National Police on Kimpo (who cooperated with the KPR in security matters) included the STAYBACK LINE to the north of the peninsula. As a rule, no civilians other than those with daytime farming permits, were allowed beyond this line. Numerous regulations were also issued to control boat traffic. Surrounded by rivers on three sides, there was ample opportunity for enemy agents or line crossers to infiltrate the defense line, despite continuous screening by friendly outposts and waterborne patrols.

Two months after the “heavy” June shelling came the August floods, which were more destructive than the artillery had been. The rest of the summer and fall followed a fairly regular, uneventful pattern with customary defense duties, rotation of frontline units, and training exercises. Among the latter were four helicopter demonstrations in October and a five-hour communication CPX (Command Post Exercise) the following month.

One episode toward the end of the year created a temporary stir in the daily routine. In late November, two Communist espionage agents and their North Korean guides were apprehended on the west bank of the Han, almost directly east of the Kimpo Airfield. They had crossed the Imjin-Han Rivers by boat, using this normal infiltration route to penetrate the Marine defense net. The agents were seized by National Police on 22 November and their North Korean guides two days later. It was unusual for agents and guides to be captured so closely together. Normal defense measures of the peninsula had assigned separate northern, western, and southern sector units for protection against possible amphibious or overland attacks or--far more likely--enemy infiltration.

The following month four more “roving” two-man outposts were established in the western coastal area of the southern sector. Manned from sunset to 30 minutes after sunrise daily by either KPR military personnel or National Police, the outposts occupied different positions each night. They were responsible for checking for proper identification and enforcing the rigid 2100–0500 curfew hours. Another unusual occurrence took place the last four nights of December when a single-engine light aircraft dropped propaganda leaflets in Colonel Harvey C. Tschirgi’s[334] sector.

[334] Colonel Tschirgi had taken command of the KPR on 1 December from Colonel Richard H. Crockett, who previously relieved Colonel Staab (the original KPR commander) on 31 August.

Commanded by Lieutenant Colonel Dobervich, the 1st Amphibian Tractor Battalion (minus Company A at KPR, and Company B at Pohang), reinforced by the Division Reconnaissance Company, had manned positions on the KANSAS line since April 1952. By the end of May, the battalion had inserted an additional unit, a provisional company,[335] in the KANSAS secondary defense line. In July, the amtrac company relieved the reconnaissance company on line, the latter then becoming part of Headquarters Battalion, 1st Marine Division. All amphibian tractor battalion units assigned to ground defense missions received special refresher training in infantry operations, including the employment of forward observers.

[335] Comprising a platoon from Company B and several headquarters elements, the provisional company was disbanded on 14 June when Company B that had been supporting MAG-33 at Pohang was reassigned to the battalion.

During the first summer in the west, the mainland-based amphibian organization continued its KANSAS defense mission. The battalion also instituted a training program for patrolling the Han River by tractor. (Company A, attached to the KPR, had conducted waterborne patrols of the Yom since June. The unit also manned outposts along that river.) Headquarters and Service Company assisted the U.S. Army in laying a signal cable across the river during August, the same month Lieutenant Colonel Dobervich relinquished unit command to Lieutenant Colonel Edwin B. Wheeler. In late August the battalion sent 58 of its members to help augment 1st Marines ranks, thinned by the fierce Bunker Hill fighting.

Through the end of 1952, the 1st Amphibian Tractor Battalion continued its KANSAS mission. Although the sector had witnessed relatively little action for some months, several incidents about this time varied the generally quiet daily routine. In October, Company B (Major Charles W. Fitzmaurice) sent out an amphibious patrol to capture prisoners (Operation CAT WHISKER). The plan was to cross the Han in a rubber boat and set up an ambush after reaching the enemy shore, but a storm-angered river, with a strong tide boosted by heavy winds, prevented landing of the boat. Two months later, another snare--this one set by the enemy--was partially successful. Several hours after dark on 1 December, the jeep assigned to the battalion commander, Major George S. Saussy, Jr.,[336] was being driven on the MSR by Private First Class Billy J. Webb, its operator and only occupant.

[336] Formerly the executive officer, Major Saussy took over unit command on 7 November, when Lieutenant Colonel Wheeler was transferred to the 5th Marines. Lieutenant Colonel Frank R. Wilkinson, Jr., became the next commanding officer on 16 March 1953.

Suddenly shots rang out from the side of the road. Within a few seconds, 23 bullets from a Russian-made submachine gun had struck the jeep; the driver, astonishingly, received only a knee wound. No trace of the ambushers could be found by the friendly patrol dispatched to investigate the incident. An activity of an entirely different nature that same month was the assignment of battalion LVTs to break up the heavily encrusted ice that had formed around and endangered supports of three bridges in the I Corps area. A rash of minor incidents involving would-be, but unsuccessful, enemy infiltrators also took place during the winter months in the amtrac sector. In November, three agents attempted to cross the Imjin on their way to the division area, but were engaged by a battalion patrol. After a brief fire fight, friendly artillery was called down on the retreating boat and it was believed destroyed. Enemy agents on foot were engaged by National Police or Marine listening posts again in January and March and deterred from their espionage missions.

Commitment to an infantry role in the KANSAS line, meanwhile, had permitted little time for operation of the battalion tractors. In December, construction began on a storage park for those LVTs not in use. By placing the non-operating tracked vehicles in a single area, the battalion could handle routine maintenance with just a few men. This facility, located at Ascom City, was completed early in 1953. By March, a total of 34 tractors had been placed there in caretaker status. Implicit in this economy measure was the requirement that all stowed tractors could revert to combat status, if necessary, on a 48-hour alert.

_Changes in the Concept of Ground Defense_[337]

[337] The material in this section is derived from: _PacFlt EvalRpt_ No. 5, Chap. 8.

During the winter months of 1952–1953, the 1st Marine Division modified the organization of its tactical defense, although it retained the basic concept of the combat outpost system as the backbone of MLR defense.[338] Development of much of the KANSAS line and parts of the Marine MLR during this period reflected several new ideas on how the ground defense could be better organized. Recent experience during Communist attacks had shown that defensive emplacements and positions could be dug deeper and below ground to withstand massed enemy fires. Contrary to traditional concepts, it had also been found that centering the defense on the military crest[339] of a hill was not always the best procedure. Emplacement of machine guns downslope or in low firing positions to cover draws or flat ground was not entirely suitable to the Korean terrain, enemy, or nature of positional warfare.

[338] The 1st Commonwealth Division, to the Marine right, utilized a different defense system. Instead of relying on the COPs forward of the main line of defense as major deterrent positions, the British preferred to include all strategic terrain features within the MLR itself. They followed a policy of active patrolling to the front and, at night, occupied selected ground sites, preferring to fight the enemy from their main battle positions rather than from more isolated COP positions. _PactFlt EvalRpt_ No. 6, Chap. 9, pp. 9-92, 9-93.

[339] The military crest is that point along the slope of a hill from which maximum observation up and down the hill can be obtained. The topographical crest is the highest point on a hill or ridge.

Altered defense concepts, beginning in October, took the following form:

(1) The trace of defensive positions followed the topographical crest (A) rather than military crest (B) of key terrain features. (Map diagrams 20 and 21 illustrate these changes.)

(2) Fighting positions and emplacements were dug a short distance downslope (C) from the topographical crest.

(3) Trenches on the topographical crest permitted easier, faster, and more protected access to fighting positions from the reverse slope and support area (D).

(4) Positions on the topographical crest were less vulnerable to enemy artillery because it was more difficult for the enemy to adjust his fire on these positions than on trenches dug along the military crest. Many shells simply passed over the top (E) of the hill.

(5) Certain hills and noses were selected and organized so that trenches and gun emplacements, encircling the crest, would form mutually supporting positions (X).

(6) Machine guns were moved from the draws (Y) to hilltops and noses (Z) where better long-range observation and fields of fire existed.

Another change in the improvement of field fortifications came into use during the winter months. A different type of barbed wire obstacle, called “Canadian,” “random,” or “double-apron” wire, began to find favor with Marine infantrymen. Canadian wire consisted of two parallel rows of three-strand barbed wire fencing, erected about three feet apart. The void was filled in with additional barbed wire, placed at random, but connected to the parallel fences.[340] The new type barbed wire appeared more effective for several reasons. Besides being simple and fast to emplace, Canadian wire merely became more entangled by artillery shelling, which quickly ripped apart the standard double-apron barbed wire previously used in COP slope defenses.

[340] Commenting on the heavy destruction of Hook fortifications by CCF preparation, one 7th Marine company commander stated: “Enemy artillery and mortars did tend to destroy the protective wire. We noted especially that the Canadian ‘Random Wire,’ although it tended to move about under fire, did hold together and continue to offer good protection.” _McLaughlin ltr._

_Before the Nevadas Battle_[341]

[341] Unless otherwise noted, the material in this section is derived from: _PacFlt EvalRpt_ No. 6, Chap. 9; 1stMarDiv ComdDs, Feb-Mar 53; 1stMar ComdD, Mar 53; 5thMar ComdDs, Feb-Mar 53; 7thMar, 11thMar, 1st TkBn, 1/5, 2/5, 1/7 ComdDs, Feb 53.

As the Marine division continued to revamp and strengthen its primary defenses, a change of pace on the battlefront was gradually being felt. Only a few major raids had taken place during November, December, and January, and these involved no transfer of real estate. Casualties had been light. Artillery rounds, both incoming and outgoing, had dropped substantially. By February, however, it became apparent that the period of winter inactivity was nearing an end.

Taking the initiative in the renewed action was the 5th Marines, occupants of the right regimental sector since 25 January. The next month the regiment conducted three successful daytime raids against fortified enemy positions. Targets for the initial action, on 3 February, were two consistently troublesome hills, 31 and 31A in the Ungok Hill mass, north of the left battalion sector.

Since all battalions of the 5th Marines were to be involved either directly or indirectly in Operation CLAMBAKE, the initial planning and actual execution of the raid was to be carried out by the regimental commander, Colonel Walt. CLAMBAKE required especially thorough coordination of the heavy fire support since it was to be launched with a tank-artillery feint against several CCF positions (Hill 104, Kumgok, and Red Hill) generally west of the Ungok objective area. The two target hills were to be assaulted by reinforced platoons from Company A (Captain Don H. Blanchard) of the reserve battalion, 1/5, commanded by Lieutenant Colonel Jonas M. Platt, who was responsible for the later planning stages of the raid. It was anticipated that intensive air and artillery preparation on the feint objectives and movement of gun and flame tanks during the diversion would gain the element of surprise for the assault platoons. Thus the Marines hoped to take prisoners, the main purpose of the raid, and to kill enemy troops and destroy their defenses.

During the five weeks of preparation, every aspect of the maneuver was thoroughly reviewed and rehearsed. All participating units took part in the planning conferences. Routes were reconnoitered, mines cleared, and fire concentrations plotted and registered. MAG-12 pilots studied the target areas from the nearby Marine MLR. Six rehearsals, including practice in casualty evacuation, uncovered potential problem areas. Final rehearsal was held 1 February, with artillery and air preparation made against the feint objectives. Four close air support strikes were conducted that day and the next as part of the plan to divert enemy attention from the CLAMBAKE destruction mission.

Shortly after first light on 3 February, three platoons of tanks rumbled across the MLR to assault the feint area. A heavy “false” artillery preparation by 1/11 was also placed on the three western enemy hills as well as direct fire from gun and flame tanks. The two Marine assault forces, one against each hill, moved out armed with flamethrowers, 3.5-inch rockets, machine guns, grenades, satchel charges, bangalore torpedoes, and automatic weapons. Enemy forces occupying the positions made three separate counterattack attempts, which were blunted by Marine supporting arms. During the infantry attack, friendly air hovered on station and artillery fired continuous counterbattery and countermortar fire.

With the exception of the change of withdrawal route of one of the assault teams, the 5th Marines reported that the operation was carried out according to plan. Company A tanks had swung left across the frozen rice paddies to provide left flank security for the infantry and to interdict trenchlines that connected with the Ungok objective. Intense enemy fire lashed the armored vehicles as they approached Kumgok and Red Hill as well as those supporting tanks that remained on the MLR.[342] Air, artillery, infantry, and tanks produced an estimated 390 Chinese casualties (including 90 known KIA) in addition to damaged or destroyed trenchlines, tunnels, caves, bunkers, and weapons of the enemy. Marine losses were 14 killed and 91 wounded. One flame tank was lost.

[342] For a detailed account of the tank action in the CLAMBAKE raid see Col Clyde W. Hunter ltr to Dir MCHist, HQMC, dtd 6 Jun 70, in v. V, Korean comment file.

As in the case of the 1st Marines WAKEUP raid in November 1952, CLAMBAKE was important not so much in accomplishing its primary mission (actually, no POWs were taken) as in lessons learned. One of these was to reemphasize the fact that thorough preparation helped to ensure smooth coordination of infantry and supporting arms. In his report of the operation, Lieutenant Colonel Platt wrote, “minute planning to the last detail along with carefully executed rehearsals are basic to success in actions of this type.”[343] He further noted that “confidence and enthusiasm stimulated by the rehearsals are assets which cannot be overlooked.”[344] The battalion commander also commented on the importance of planning for both troop withdrawal and maintaining a flexible schedule of fires by supporting arms. Air,[345] artillery, and tanks all employed fire plans that could be readily adjusted to meet the changing tactical situation.

[344] _Ibid._

[345] In order to assure better close air support during the assault; an SOP for the airborne tactical controller was proposed and drafted by MAG-12 for 1st MAW approval. The plan utilized the marking of targets by rocket and subsequent corrections to be made by the FAC. This enabled MAG-12 aircraft “to scramble, fly a CAS mission at the Division front and be back at the field at K-6 in approximately 40 minutes.” Col Wayne M. Cargill ltr to Dir MCHist, HQMC, dtd 8 Jan 70.

On the ground, flame was found to be the best weapon for neutralizing the well-fortified CCF caves. From Company A, 1st Tank Battalion (Captain Hunter) came information about Chinese 3.5-inch rocket launcher teams used in antitank defense. Several of these tank-killer teams had run down the trenchline holding small bushes in front of them. The enemy then boldly advanced through a hail of bullets to within 15–20 yards of the Marine tank before opening fire with their rockets. Short bursts of flame from headquarters tanks soon caused even the most intrepid to beat a hurried retreat.

Concluding his after-action report of CLAMBAKE, the regimental commander, Colonel Walt, observed:

In addition to inflicting large numbers of casualties and destruction upon the enemy, the operation served a secondary purpose, none the less important. It provided excellent training and experience for the various infantry and supporting arms staffs involved, helping to develop them into a smoothly functioning infantry-air-artillery-tank team.[346]

[346] 5th Mar ComdD, Feb 53, App. VI, dtd 20 Feb 53, p. 3.

Shortly before the end of the month, the 5th Marines made another major assault. As in the earlier CLAMBAKE, this raid was again in two-reinforced-platoon size and made during the early daylight hours of 25 February. This time the objective was a single height, Hill 15 (Detroit), two miles east of the CLAMBAKE objective. Lieutenant Colonel Oscar F. Peatross’[347] 2/5, manning the extreme right sector of the division, gave the assignment to Company F, then under Captain Harold D. Kurth, Jr. Planning for Operation CHARLIE, a standard-type kill, capture, and destroy raid, was carried out in much the same detailed manner as the earlier 1/5 raid.

[347] Lieutenant Colonel Peatross had succeeded Lieutenant Colonel McLaughlin as battalion CO on 11 Sep 52.

CHARLIE differed somewhat in concept in that the 2/5 operational plan attempted to gain surprise by launching the attack during the BMNT[348] period as well as in use of smoke to screen enemy observation. Supporting arms preparatory fires had been carefully plotted, including the precision destruction aerial bombing that had proved so effective in the CLAMBAKE assault. In actual execution of CHARLIE, however, bad weather prevented the use of almost all the planned pre-D-Day and D-Day air strikes. Upon reaching the Detroit objective area assault Marines “found the majority of enemy installations were relatively undamaged, even though subjected to heavy bombardment by other supporting arms.”[349] Artillery preparatory fires had been employed successfully to isolate the battle area and howitzer and tank missions supported the raid.[350]

[348] Beginning morning nautical twilight is that period before sunrise or after sunset (BENT, or beginning evening nautical twilight) when visibility is limited to approximately 300 yards.

[349] 5thMar ComdD, Feb 53, App. VI, dtd 28 Feb 53, p. 5.

[350] In nearly three hours of firing, the 11th Marines and its reinforcing and attached units, including the 1st Royal Canadian Horse Artillery, expended 11,881 rounds. Indicative of the meticulous planning that preceded an operation such as CHARLIE is the 11th Marines report of this raid, 11thMar ComdD, Feb 53.

Between the time of CLAMBAKE and CHARLIE a series of Marine and enemy small units actions erupted which were soon to become a way of life for the MLR combatants. By sporadic outpost attacks and increasing their use of artillery, the Chinese were beginning to demonstrate a more aggressive attitude than in recent months. On the night of 12–13 February, a CCF platoon supported by mortars and artillery probed COP Hedy (Hill 124), in the right battalion of the center regimental sector, held by Lieutenant Colonel Barrett’s 3/7. On the next night, it was the Korean Marines who turned aggressor. Two of their platoons raided Hill 240, on the west bank of the Sachon, nearly three miles north of the mouth of the river. The following night, a 7th Marines patrol moving into ambush positions was itself stalked by a large CCF patrol. When reinforcements, including armored vehicles, moved out from the MLR to support the Marines, the Chinese hastily withdrew.

Three more contacts were made before the end of the month along the division front. On 19 February CCF soldiers, in two-platoon strength, engaged KMC sentries forward of COP 33, located about a mile east of the action the previous week. After the initial exchange of small arms fire, the Koreans moved back to the outpost and called down supporting fires on the Chinese. Artillery and mortars tore into the attackers causing numerous casualties and forcing the enemy to withdraw. On the morning of 22 February, a raiding party from the 5th Marines assaulted a smaller enemy force at Hill 35A, approximately 1,300 yards southwest of the Ungok hills. In this second raid staged by the 5th Marines that month, assault troops (H/3/5) used flamethrowers in the early stages of the action to help clear enemy trenches of hostile grenade throwers.

Late the next night a 7th Marines unit, consisting of a reinforced platoon and four M-46 tanks, set out to raid Yoke, located near the peace corridor five miles north of Freedom Bridge. The assault against that position never came off. At 2137 as the B/1/7 platoon moved into preliminary positions on Hill 90, north of the ultimate objective, a Chinese company ambushed the patrol from three sides. When the Marines closed with the enemy in hand-to-hand fighting, a support platoon was sent from the MLR. After an intense 30 minute fire fight, the CCF began withdrawing at 0138. Enemy losses were listed as 45 counted KIA, 33 estimated KIA, and 35 estimated WIA. As a result of the assault, orders for the 7th Marines raid on Yoke were cancelled. Marine casualties numbered 5 killed, 22 wounded.

Whereas February was characterized by a marked increase in ground contacts between Marines and their CCF adversaries, during the first part of March the Chinese again assumed an inactive posture. Marine patrols reported few contacts. Except for a KMC raid on 3 March, little action that could be considered a sizable engagement took place until after midmonth. On the 16th there was a brief skirmish involving a 5th Marines combat patrol near Reno and a short fire fight between Carson defenders and an enemy squad. The next night a Chinese platoon, waiting near Vegas for a Marine patrol to pass by, was itself put to flight by the patrol.

Two encounters with the CCF on 19 March marked the heaviest action yet of the month. Early that morning, a predawn raid was staged by B/1/5 (Captain Theodore J. Mildner) at Hill 31A, one of the Ungok twin objectives in CLAMBAKE the previous month. The March ITEM raid employed 111 Marines. One platoon was to make the assault and the second platoon to support the operation and assist in casualty evacuation. Following a series of nearly a dozen air strikes on the objective and artillery preparation, Captain Mildner’s two assault platoons jumped off from the MLR check point at 0518. As usually happened in such operations, the preliminary fire drove the Chinese to reverse slope defenses. No enemy POWs were taken and at 0700 the Marine units disengaged, due to casualties sustained from enemy shelling and machine gun fire.[351]

[351] Prior to the raid various combinations of flamethrower fuels and pressure were extensively used. The purpose was to determine the maximum effective range of the flamethrower teams in order to “neutralize the hand-grenade throwing potential of the enemy, this being one of the major problems confronting assault elements on other raids.” Final tests resulted in flame being thrown more than 40 yards up hill. 1/5 ComdD, Mar 53, App. IVf, p. 3.

Earlier that same date, two attacks had been made simultaneously by the enemy on outposts in the center regimental sector, where the 1st Marines had relieved the 7th on 10 March. At 0105 one CCF company struck in the vicinity of Hedy while a second lunged at Esther, about 1½ miles east. When a G/3/1 reconnaissance patrol operating forward of COP Esther observed enemy movement, the Marines pulled back to the outpost, alerting it to the impending attack. After a heavy incoming artillery barrage, the enemy assaulted the outpost, but when a three-hour effort failed to carry the position, the attackers withdrew. By that time the Chinese company which had hit COP Hedy had also broken off the attack.

Actually the fight in Captain Carl R. Gray’s Company H sector, to the rear of Hedy, was mainly at the MLR, for the Chinese indulged in merely a brief fire fight at the latter outpost, bypassing it in favor of a crack at JAMESTOWN. The main line of resistance failed to yield to the enemy thrust, which was supported by 2,400 rounds of mortar and artillery fire along the MLR and outposts.

After being thwarted by Hedy-Esther defenses, the enemy shifted his efforts westward to the 1st KMC area. The Korean regiment received the brunt of the enemy’s minor infantry probes immediately preceding the Nevada Cities battle. Late on 25 March a series of skirmishes broke out in the 1st Marines sector between one-or-two platoon size Chinese infantry forces and Marine outpost defenders. Following a quiet daylight spell on the 26th, the Chinese resumed the offensive with a probe at COP Dagmar. This coincided with what developed into a massive regimental assault unleashed against Carson, Reno, and Vegas, outposts in the 5th Marines sector, to the right. There Colonel Walt’s regiment would shortly be the target of the bloodiest Chinese attack to date on the 1st Marine Division in West Korea.
