It is not likely that the date 25 June 1951 meant much to the Marines on the KANSAS Line. In all probability few of them recalled that it was the first anniversary of the Communist aggression which started the war in Korea.
Since that surprise attack on a June Sunday morning in 1950, some 1,250,000 men had been killed, wounded or captured in battle--a million of them from the Communist forces of Red China and the North Korean People’s Republic. This was the estimate of J. Donald Kingsley, Korean reconstruction agent general for the United States. He reckoned the civilian victims of privation, violence, and disease at two million dead. Another three million had been made homeless refugees.[239]
[239] This section is based on by Peter Kihss, “One Year in Korea,” _United Nations World_, Vol. 5, No. 7, July 1951, 21–23.
On 25 June 1951 the Communists held less territory by 2,100 square miles than they occupied when they began their onslaught with an overwhelming local superiority in arms and trained troops. Losses of Communist equipment during the first year included 391 aircraft, 1,000 pieces of artillery, and many thousands of machine guns, automatic rifles, and mortars. North Korea, formerly the industrial region of the peninsula, lay in ruins. Cities, factories, and power plants had been pounded into rubble.
In short, the thrifty conquest planned by the Koreans and their Soviet masters had backfired. Not only had the Communist offensives of April and May been stopped; the United Nations forces had rebounded to win their greatest victory of the war’s first year. While X Corps was advancing to the Punchbowl, other major Eighth Army units had also gained ground. Perhaps the most crushing blow was dealt by I Corps in its attack on the Iron Triangle. Units of two U.S. infantry divisions fought their way through extensive mine fields into Chorwon and Kumhwa on 8 June. By the end of the month, I Corps held defensive positions about midway between the base and apex of the strategic triangle that had been the enemy’s main assembly area for the troops and supplies of his spring offensives.[240]

On the east-central front, units of IX Corps pushed within 10 miles of Kumsong while I ROK Corps advanced along the east coast to Chodo-ri. Thus the UN forces occupied the most favorable line they had held since the great CCF offensive early in January. From the mouth of the Imjin this line ran northeast to the middle of the Iron Triangle, eastward across the mountains to the southern rim of the Punchbowl, then northeast to the coast of Chodo-ri (Map 14).
_Communists Ask for Truce Talks_
The first anniversary of the Korean conflict was overshadowed two days earlier by the news that the Communists had taken the initiative in proposing truce talks. The suggestion was made in a New York radio address of 23 June by a Soviet delegate to the United Nations--Jacob Malik, Foreign Minister of the USSR. On the 25th the idea was unofficially endorsed in a radio broadcast by the Chinese Communist government. UN officials immediately indicated their willingness to discuss preliminary terms. The outcome was an agreement that representatives of both sides would meet on 7 July at Kaesong, then located between the opposing lines in west Korea.
Why had the Communists been first to ask for a truce conference? Both Generals Van Fleet and Almond believed that the answer might have been traced to military necessity rather than any genuine desire for peace. “I felt at that time that the Chinese Communists and the North Korean armies were on the most wobbly legs that they had been on to that date,” said General Almond when interviewed shortly after his retirement in 1953. “They were punch drunk and ineffective, and I, personally, thought at that time that it was the time to finish off the effort.”[241]
[241] _U.S. News and World Report_, 13 Feb 53, 40–41.
Raymond Cartier, representing a Paris newspaper, probably spoke for most of the correspondents at the front when he suspected that the proposal for truce talks “was possibly just a crafty trick devised by the Communists to gain time and build up again the badly mauled Chinese armies.”[242]
[242] _UN World_, Vol. 5, No. 10, Oct 51, 10.
It might have been recalled at this time that the Communists had used truce negotiations for military purposes during the Chinese Civil War. In 1945 and 1946, when prospects for a Nationalist victory were bright, the enemy took advantage of American peace efforts by agreeing on several occasions to meet for truce conferences. And while prolonging the talks by all manner of subterfuges, the Communists profited from the breathing spells by regrouping their forces and planning new offensives. Their final triumph, in fact, owed in no small measure to interludes when the conference table served a military purpose.[243]
[243] U.S. State Department Publications 3573, Far East Series 30, pp. 352–363.
History repeated itself in June and July 1951 when events of the next two years were shaped by the political decisions of a few summer weeks. Indeed, Admiral C. Turner Joy believed that the war was actually prolonged rather than shortened as a result of the negotiations.
“Military victory was not impossible nor even unusually difficult of achievement,” wrote the Senior Delegate and Chief of the UN Command delegation at the truce talks. “Elimination of the artificial restraints imposed on United States forces, coupled with an effective blockade on Red China, probably would have resulted in military victory in less time than was expended on truce talks.”[244]

One of Admiral Joy’s last services to his country before his death in 1956 was the writing of this book. Other sources for this section are William H. Vatcher, Jr., “Inside Story of Our Mistakes in Korea,” _U.S. News and World Report_, 23 Jan 1953, 35–36; E. Weintal, “What Happened at Kaesong and What is in Prospect,” _Newsweek_, 23 Jul 1951, 38; Comments n.d., Col J. C. Murray.
Mao Tse-tung’s forces had lost face by the failure of their long heralded 5th Phase Offensive. They had been badly beaten during the UN counteroffensive. Pretensions of high CCF morale could no longer be maintained when troops were laying down their arms without a fight. Nor could charges of low UN morale be supported when the fighting spirit of the Eighth Army was being shown every day at the front.
In view of these circumstances, it would appear that the Communists had poor cards to play against United Nations trumps at a truce conference. But they played them so craftily, with such a sly sense of propaganda values, that the victors of the May and June battles were soon made to appear losers begging for a breathing spell.
To begin with, the Chinese knew that the mere public announcement of the possibility of truce talks would have a tremendous appeal in the United States, where the war was unpopular. Pressure would be brought upon Washington to meet the enemy immediately for negotiations. And while a cease fire remained even a remote prospect, American public opinion would demand a slackening of offensive military operations with their attendant casualties.
From the outset it was apparent that the United Nations Command was no match for the Communists in low cunning. The UN suggested, for instance, that the truce teams meet on the Danish hospital ship _Jutlandia_. Here, surely, was neutral ground, since the Danes had no combat forces in Korea. Moreover, the ship was to be anchored in Wonsan harbor within range of CCF shore batteries.
The Reds won the first of many such concessions with their refusal. They insisted that the talks be held at Kaesong, and the UN Command let them have it their way. The reason for the Communist decision was soon made evident. Kaesong was in the path of the advancing Eighth Army, which meant that an important road center would be immune from attack. And though the ancient Korean town was originally in no man’s land, the Communists soon managed to include it within their lines.
All delegates were requested to display white flags on their vehicles for identification. Communist photographers were on hand to snap countless pictures of UN delegates which convinced Asia’s illiterate millions at a glance that the beaten United Nations had sent representatives to plead for terms. If any doubt remained, other photographs showed the unarmed UN delegates being herded about Kaesong by scowling Communist guards with burp guns.
No detail of the stage setting was too trivial to be overlooked. Oriental custom prescribes that at the peace table the victors face south and the losers face north. Needless to add, the UN delegates were seated at Kaesong with a view to enhancing Communist prestige.[245]
[245] Joy, _How Communists Negotiate_, 4–5.
Some of the propaganda schemes bordered on the ridiculous, “At the first meeting of the delegates,” Admiral Joy related, “I seated myself at the conference table and almost sank out of sight. The Communists had provided a chair for me which was considerably shorter than a standard chair. Across the table, the senior Communist delegate, General Nam Il, protruded a good foot above my cagily diminished stature. This had been accomplished by providing stumpy Nam Il with a chair about four inches higher than usual. Chain-smoking Nam Il puffed his cigarette in obvious satisfaction as he glowered down on me, an obviously torpedoed admiral. This condition of affairs was promptly rectified when I changed my foreshortened chair for a normal one, but not before Communist photographers had exposed reels of film.”[246]

_Patrol Bases on_ BADGER _Line_
The war went on, of course, during the negotiations. But the tempo was much reduced as the UN forces consolidated their gains, and the enemy appeared to be breaking off contact at every opportunity. Generally speaking, the Eighth Army had shifted from the offensive to the defensive. In keeping with this trend, the 1st Marine Division occupied the same positions for nearly three weeks after fighting its way to the BROWN Line.
On 22 June all three infantry regiments were directed to establish battalion-size patrol bases on the BADGER Line--1½ to 2½ miles forward of their present positions. In the 1st Marines sector 3/7 was attached to Colonel Brown and ordered to relieve 3/1 on the left flank of the regiment. The purpose was to free 3/1 to move forward and establish a patrol base on Hill 761, about 1,000 yards forward of the MLR.
While these arrangements were being carried out, General Almond called at the 1st Marines CP. He expressed surprise that the establishment of patrol bases was being contemplated by EUSAK when some of the front-line units were still in contact with the enemy.[247]
[247] 1stMarDiv _HD_, Jun 51, 55.
Execution of these orders was accordingly suspended. The following day, however, Division again alerted the infantry regiments to be prepared to occupy patrol bases on order. This was by direction of Corps, which in turn had been directed by EUSAK.
The Marine regimental and battalion commanders were not happy about this turn of affairs. The patrol base concept had been tried out early in May, during the lull between the enemy’s two offensives, and found wanting. In theory it was a good means of keeping contact with an enemy who had pulled back out of mortar and light artillery range. In practice the enemy had shown that he could bypass patrol bases at night for probing attacks on the MLR. The bases themselves ran the constant risk of being surrounded and overwhelmed. As a final objection, a regiment was often deprived of its reserve battalion, which was the logical choice for such duty.
In compliance with orders, 3/1 moved out on 26 June and established a patrol base on Hill 761. This position received such a bombardment of large caliber mortar fire that Colonel Brown pulled the battalion back to the MLR the following day.[248]
[248] CO 1stMar msg to CG 1stMarDiv, 0815 27 Jun 51.
General Thomas gave his opinion of the patrol base concept after his retirement when he summed it up as “an invitation to disaster.”[249] He could only carry out orders, however, when Corps directed early in July that a patrol base be established on Taeu-san.
[249] Gen G. C. Thomas interv, 6 Feb 58. It is interesting to note that there was no mention of the patrol base concept in the then current _Field Service Regulations, Operations, FM 100-5_, published by the Department of the Army in August 1949.
This 4,000-foot peak, located some 2 miles north of the MLR, afforded excellent observation eastward into the Punchbowl and westward into the So-chon River Valley. The enemy, of course, was aware of these advantages and had made Taeu-san a strongpoint of his MLR. This was clearly indicated by the stiff resistance encountered by KMC reconnaissance patrols.[250]
[250] Unless otherwise specified, the remainder of this section is based on 1stMarDiv _HD_, Jul 51, 7–11; Col C. W. Harrison’s account, “KMC Attack on Taeu-san, 8-11 July 1951;” Col G. P. Groves, ltr of 9 Apr 58.
Nevertheless, Division G-3 was suddenly alerted on the morning of 7 July by the Marine Liaison Officer with X Corps to expect an order directing the setting up of a patrol base on Taeu-san the following day. The KMC Regiment, warned by telephone, had little time for planning and organizing an attack. Since the KMCs could not be relieved for responsibility for their sector, it was necessary to form a composite battalion of the three companies that could most conveniently be relieved. Unfortunately, they contained a large proportion of recruits, and the battalion commander was a new arrival.
There were two avenues of approach. One was along an open, fairly level, ridgeline that extended from the KMC positions. The other called for a descent into the stream-bed generally paralleling the MLR and a steep climb up a ridge leading directly north to Taeu-san.
Both routes of approach were used. One company advanced on the right by way of the stream bed and two companies took to the ridgeline on the left. The assault was to have been preceded by air strikes and an artillery bombardment, but bad weather kept the aircraft grounded.
The attack jumped off at 1030 on 8 July. All three companies were greeted by enemy mortar and machine gun fire that pinned down the company on the right. The two companies on the left won a foothold on Hill 1100, about a mile in front of Taeu-san. Here the advance ground to a halt.
These KMCs dug in for the night and repulsed a series of counterattacks. On the morning of the 9th the KMC regimental commander, Colonel Kim Tai Shik, committed the entire 1st Battalion to the attack on the right. It had no better success than the company of the day before. Meanwhile, the two companies were driven off Hill 1100.
Colonel Gould P. Groves, senior liaison officer with the KMCs, recommended that the remnants of the two companies be withdrawn. The 1st Battalion had managed to capture Hill 1001, but it was plain that the KMC regiment could not come close to Taeu-san. On 12 July the 1st Marine Division informed X Corps that the position held by the KMCs just forward of Hill 1001 fulfilled the requirements of an advance patrol base. As far as the Marines were concerned, the sad affair was permitted to rest there.
As evidence of the valiant effort made by the KMCs, they suffered 222 casualties. A sequel to this story was written late in July after the 2d infantry Division relieved the Marines. X Corps again ordered the capture of Taeu-san as a patrol base, and it required the commitment of the major part of the division to accomplish the task.[251]
[251] X Corps _Cmd Rpt_, Jul 51, 13; 2dInfDiv _HD_, Jul 51, 13–19.
Although the fighting had not been severe for other units of the 1st Marine Division during the first two weeks of July, the casualties (including KMC losses) were 55 KIA, 360 WIA, and 22 MIA--a total of 437. Relief of the Marines was completed by the 2d Infantry Division on 15 July, and by the 17th all units were on their way back to assembly areas in X Corps rear.
It was the second time since the landing of the 1st Provisional Marine Brigade on 2 August 1950 that the Marines had been away from the firing line for more than a few days.
_Red Herrings at Kaesong_
It is not changing the subject to switch to the truce talks. Kaesong was actually a second UN front.
After the preliminaries had been settled--most of them to Communist satisfaction--the UN delegation, headed by Admiral Joy, held a first meeting on 10 July 1951 with his opposite number, NKPA Major General Nam Il, and the Communist truce team. This was the first of the talks that were to drag on for two dreary years.
Nam Il, a Korean native of Manchuria, born in 1911, had been educated in Russia and had served with the Soviet army in World War II. His career in Korea began when he arrived as a captain with Soviet occupation troops in 1945. Rising to power rapidly, he took a prominent part in the creation of a Soviet puppet state in North Korea.
An atmosphere of sullen hatred surrounded the UN delegates at Kaesong. The CCF sentinel posted at the entrance to the conference room wore a gaudy medal which he boasted had been awarded to him “for killing forty Americans.” When Admiral Joy tried to send a report to General Ridgway, the messenger was turned back by armed Communist guards. These are samples of the indignities heaped upon the UN truce team. After several UN delegates were threatened by guards with burp guns, Joy protested to Nam Il, “demanding prompt elimination of such crudities.”
In order to give their battered armies more time for recuperation, the Communist delegates met every issue with delaying tactics. They proved themselves to be masters of the ancient art of dragging a red herring across the trail. Going back on their word did not embarrass them in the least if they found it to their advantage to renege.[252]
[252] This section, except when otherwise noted, is derived from the following sources: Joy, _How Communists Negotiate_, 6–10, 129, 140; Carl Berger, _The Korean Knot_ (University of Pennsylvania Press, 1957), 141–151; Comments n.d., Col J. C. Murray.
The truce negotiations were bound to have an immediate effect on military operations. In the United States it seemed a pity to newspaper readers that American young men should have to die in battle at a time when headlines were hinting at the possibility of peace. Mothers wrote to their congressmen, requesting a halt in Korean operations.
General Van Fleet minced no words after his retirement when he commented on the effect of the truce talks on strategy:
Instead of getting directives for offensive action, we found our activities more and more proscribed as time went on. Even in the matter of straightening out our lines for greater protection, or capturing hills when the Reds were looking down our throats, we were limited by orders from the Far East Command in Japan, presumably acting on directives from Washington.[253]
[253] Gen J. A. Van Fleet, USA (Ret.), “The Truth About Korea,” _Life_, 11 May 53, 133.
It was the opinion of Admiral Joy that more UN casualties were suffered as a consequence of the truce talks than would have resulted from an offensive taking full advantage of Red China’s military weaknesses in June 1951.
“As soon as armistice discussions began,” he wrote, “United Nations Command ground forces slackened their offensive preparations. Instead, offensive pressure by all arms should have been increased to the maximum during the armistice talks.... I feel certain that the casualties the United Nations Command endured during the two long years of negotiations far exceed any that might have been expected from an offensive in the summer of 1951.”[254]
[254] Joy, _How Communists Negotiate_, 166.
_1st Marine Division in Reserve_
Most of the 1st Marine Division units were in X Corps reserve during the last two weeks of July 1951. The 5th Marines, however, remained in “ready reserve” near Inje under the operational control of X Corps. Toward the end of the month, the 3d Battalion of the 11th Marines passed to the operational control of the 2d Infantry Division. Meanwhile, the 7th Marines and Division Reconnaissance Company displaced to the Yanggu area to aid in the construction of defensive positions and undergo special training.
1st Marine Division Training Order 2-51, covering the period from 23 July to 20 August 1951, provided for a stiff daily schedule of general and specialist military subjects. The objectives were “to maintain each individual and unit of the command at a very high state of proficiency, while emphasizing rest and rehabilitation of personnel and repair and maintenance of equipment.... A minimum of 33% of all technical training was to be conducted at night, stressing individual and unit night discipline. Formal unit schools and on-the-job training were utilized extensively.”[255]
[255] 1stMarDiv _HD_, Jul 51, 18.
Most thoroughly covered among general military subjects were mechanical training, capabilities, tactical employment, and firing of individual and infantry crew-served weapons. Lectures and demonstrations were combined to good effect with instruction in basic infantry tactics.
“The prescribed periods of physical conditioning,” the Division report continued, “were supplemented by extensive organized athletic programs outside of training hours, resulting in the maintenance of a high degree of battle conditioning of all hands. Special military subjects encompassed the whole range of activities necessary to the accomplishment of any mission assigned the Division. Building from the duties of the individual Marine, infantry, artillery, engineer, and tank personnel progressed through small unit employment and tactics as it applied to their respective specialities. Meanwhile such diverse training as tank repair and watch repair was conducted in various units.”[256]
[256] _Ibid._
Fortification came in for study after a tour of the KANSAS Line by Major General Clovis E. Byers, who had relieved General Almond as X Corps commander. He listed the weaknesses he found and directed that “special attention [be] given to the thickness, strength and support of bunker overheads, and to the proper revetting and draining of excavations.”[257]
[257] CG X Corps, CITE X 21568.
The KMC Regiment received the most thorough training it had ever known, considering that it had been in combat continually since its organization. Each of the Division’s three other regiments sent four training teams consisting of a lieutenant, an NCO, and an interpreter to the KMCs on 22 July. The 12 teams had orders to remain until 20 August. Attached to various KMC companies, they acted as advisers for the entire training period.
Another organization of Koreans that had won its way to favorable recognition was the newly formed Civil Transport Corps (CTC). The use of indigenous labor for logistical purposes dated back to March 1951, when the Eighth Army’s advance was slowed up by supply problems caused by muddy roads. Plans were made to equip and train a special corps to assist in the logistical support of combat troops in areas inaccessible to normal motor transportation.[258]
[258] EUSAK _Cmd Rpt_, Apr 51, 1080110.
The project began on 29 March with 720 South Koreans--all from the Korean National Guard--being assigned to I Corps. Plans were developed for a Civil Transport Corps of 82 companies, each containing 240 men. The CTC was to be supervised by a staff of eight U.S. Army officers and four enlisted men under the operational control of the Transportation Section, EUSAK.
The ROK Army had the added responsibility for logistical support, of hospitalization and medical services other than emergency treatment in forward areas. Support for the CTC from UN units was to be provided in a manner similar to that in effect for the ROK forces.[259] No difficulty was found in filling the CTC ranks, for the pay meant food and clothing to a Korean and his family.
[259] _Ibid._
The Marines were always astonished at the heavy loads the Korean cargadores could carry uphill on their “A-frames,” which looked like sturdy easels with a pair of arm-and-shoulder carrying straps. Humble and patient, these burden bearers were the only means of supply in remote combat areas.
_Marine Helicopters Take the Lead_
The truce talks continued to be front-page news in August. Some of the more impulsive newspaper and radio commentators hinted at the possibility of a cease fire before the end of summer. As for the Marine command and staff, they were not so optimistic, judging from this sentence in a report:
“All Division units were notified on 14 August that requisitions had been sent to EUSAK for cold weather clothing and equipment.”
The training period afforded an opportunity to glance back over the first year of fighting in Korea and evaluate the results. There could be no doubt that the war’s foremost tactical innovation so far was the combat helicopter. The Marine Corps had taken the lead in its development when VMO-6, made up of OYs and Sikorsky HO3S-1 helicopters in roughly equal numbers, got into action with the 1st Provisional Marine Brigade in the Pusan Perimeter. Brigadier General Edward A. Craig had the historical distinction, insofar as is known, of being the first commanding general to see the advantages of a “chopper” as a command vehicle.
Evacuation of casualties was the principal job of the rotary-wing aircraft, and 1,926 wounded Marines were flown out during the first year. No less than 701 of these mercy flights took place during the three months from 1 April to 30 June 1951, covering the period of the two CCF 5th Phase offensives and the UN counterstroke. By that time the Bell HTL-4, with its built-in litters on both sides sheltered by plexiglas hoods, had taken over most of the evacuation missions from the HO3S-1.
The zeal of the pilots contributed substantially to the successful results. Captain Dwain L. Redalen gave a demonstration of the VMO-6 spirit at the height of the first CCF offensive in the spring of 1951. During the 13½ hours from 0600 to 1930 on 23 April, he was in the air constantly except for intervals of loading or unloading casualties. Logging a total of 9.6 flight hours, he evacuated 18 wounded men under enemy fire that left bullet holes in the plexiglas of his HTL-4.[260]
[260] VMO-6 Daily Flight Log, 23Apr51.
Practically all the helicopter techniques put into effect by VMO-6 had originally been developed by the Marine experimental squadron, HMX-1, organized late in 1947 at Quantico. Despite the enthusiasm for rotary-wing aircraft then prevailing, HMX-1 decided that an observation squadron should combine OYs with helicopters. The wisdom of this conclusion was proved in Korea, where the test of combat showed that both types were needed. The OYs were the superiors at reconnaissance and artillery spot missions, while the helicopters excelled at transportation and liaison and evacuation flights.
VMO-6 as a whole was the only Marine organization linking the ground and air commands. An administrative unit of the 1st MAW, the squadron was under the operational control of the 1st Marine Division.[261]
[261] This section, except when otherwise noted, is derived from the following sources: Elizabeth L. Tierney, Historical Branch, G-3, HQMC, statistics compiled from VMO-6 reports of Aug 50 to Jul 51; HMR-161 _HD_, Sep 51; 1stMarDiv type “C” rpt on assault helicopters, 4 Oct 51; Lynn Montross, _Cavalry of the Sky_ (Harper, 1954), based on Marine records, 151–158.
Thanks to the ability of the helicopter to land “on a dime,” staff liaison missions and command visits were greatly facilitated. The helicopter had become the modern general’s steed, and the gap between staff and line was narrowed by rotary wings.
The importance of wound evacuation missions can hardly be overestimated. Surgeons stressed the value of time in treating the shock resulting from severe wounds. The sooner a patient could be made ready for surgery, the better were his chances of survival. Definitive care had waited in the past until a casualty was borne on a jolting stretcher from the firing line to the nearest road to begin a long ambulance ride. Such a journey might take most of a day, but there were instances of a helicopter evacuee reaching the operation table only an hour after being wounded at the front, 15 or 20 miles away.
Captain J. W. McElroy, USNR, commanding the famous hospital ship _Consolation_, asserted that his experience had “proved conclusively the superiority of the helicopter method of embarking and evacuating casualties to and from the ship.”[262] A helicopter loading platform was installed on the _Consolation_ in July 1951, during an overhaul at the Long Beach Naval Shipyard in California. Marine helicopter pilots advised as to landing requirements, and eventually all the hospital ships had similar platforms.
[262] CO USS _Consolation_ rpt to ComNavFE, 26 Jan 52.
At a conservative estimate, the 1,926 wounded men flown out by VMO-6 helicopters during the squadron’s first year in Korea included several hundred who might not have survived former methods of evacuation.
_Marine Body Armor Tested in Korea_
Another far-reaching tactical innovation was being launched at this time as Lieutenant Commander Frederick J. Lewis (MSC) USN, supervised a joint Army-Navy three-month field test of Marine armored vests made of lightweight plastics.
A glance at the past reveals that body armor had never quite vanished from modern warfare. European cavalry lancers wore steel cuirasses throughout the 19th century. During the American Civil War two commercial firms in Connecticut manufactured steel breastplates purchased by thousands of Union soldiers. So irksome were the weight and rigidity of this protection, however, that infantrymen soon discarded it.
World War I dated the first widespread adoption of armor in the 20th century. The idea was suggested when a French general noted that one of his men had survived a lethal shell fragment by virtue of wearing an iron mess bowl under his beret. France led the way, and before the end of 1915 steel helmets were being issued to all armies on the Western Front.
When the United States entered the war, General John J. Pershing put in a request for body armor. Some 30 prototypes using steel or aluminum plates were submitted but rejected. In every instance the weight and rigidity were such that too high a price in mobility would be paid for protection.[263]
[263] This section, except when otherwise noted, is derived from the following sources: Rpt of Joint Army-Navy Mission at HQMC, 9 Nov 51, in G-4 Files; _Instructional Information, Vest, Armored_, M-1951, G-4 Files, HQMC; LCdr F. J. Lewis (MSC) USN, ltr of 21 Jun 54; Capt Louis Kirkpatrick (MC) USN, ltr of 22 Jun 54; Capt D. G. McGrew, ltr of 2 Jul 54; LtCol G. A. Hardwick, USMC, ltr of 30 Jun 54.
During the 1930’s new possibilities were opened up by developments in lightweight plastics. The Japanese attack at Pearl Harbor interrupted experiments that were not resumed until 1943. Then a new start was made with the formation of a joint Army-Navy committee headed by Rear Admiral Alexander H. Van Kueren and Colonel George F. Doriot.
Wound statistics indicated that the great majority of fatal wounds were received in a comparatively small area of the body. The following table shows the regional frequency:
NON-FATAL FATAL
_Percent_ _Percent_ Head 10 Head 20 Chest 10 Chest 50 Abdomen 10 Abdomen 20 Upper Extremity 30 Upper Extremity 5 Lower Extremity 40 Lower Extremity 5
Shell, mortar, or grenade fragments caused 60 percent of the fatal wounds, the statistics revealed, with the remainder being charged to rifle or machine gun fire. It was futile to hope for lightweight protection against high-velocity bullets. But researchers hoped that plastic body armor could stop enough shell or mortar fragments to reduce serious wounds to light wounds while preventing light wounds altogether.
Doron and nylon were the materials approved by the joint Army-Navy committee. The first, named in honor of Colonel Doriot, consisted of laminated layers of glass cloth filaments, bonded under heavy pressure to form a thin, rigid slab. That a 1/8-inch thickness could stop and partially flatten a submachine gun bullet with a muzzle velocity of 1,150 feet per second was demonstrated by ballistic tests at a range of eight yards.
The committee recommended 12-ply, laminated, basket-weave nylon for use where flexibility was required. Both the doron and nylon protected the wearer by offering enough resistance to absorb the energy of the missile, which spent itself at the impact. Thus the shock was spread out over too large a surface for a penetration, although the wearer could receive a bad bruise. If a penetration did result from a missile of higher velocity, its effects would be much reduced in severity.
Aircraft pilots and crewmen, who could tolerate more weight than foot-sloggers, were first to benefit. Flak suits and curtains were being manufactured in quantity for airmen by 1944, and the Eighth Air Force claimed a 50 percent reduction in casualties as a result.
The infantry stood most in need of protection. Statistics from 57 U.S. divisions in the European theater of operations during World War II indicated that foot soldiers, comprising 68.5 percent of the total strength, suffered 94.5 percent of the casualties. It was further established that shell or mortar fragments caused from 61.3 to 80.4 percent of the wounds.
Unfortunately, progress lagged for the ground forces, owing to conflicting requirements. Several prototype armored vests were submitted and rejected. The Marine Corps planned to conduct combat tests in the spring of 1945 by providing the ordinary utility jacket with sheaths to hold slabs of doron. A battalion of the 2d Marine Division had been selected to wear the garment on Okinawa, but the experiment was interrupted by the end of the campaign.
The Navy and Marine Corps renewed their research in 1947 at Camp Lejeune. There a new ballistics center, established for the development and evaluation of body armor, was set up by the Naval Medical Field Research Laboratory (NMFRL). Lieutenant Commander Lewis was placed in charge of experiments.
Scientific precision seemed more important than haste in time of peace, and the NMFRL was not ready with an armored vest when Communism challenged the free world to a showdown in Korea. Five hundred of the armored utility jackets of the proposed Okinawa test were available, however, and were air-shipped to the 1st Marine Division during the Inchon-Seoul operation.
Many of them went astray during the sea lift to Wonsan and subsequent Chosin Reservoir operation. Only the 50 garments issued to the Division Reconnaissance Company were worn in combat. And though this unit kept no records, the doron slabs were credited by Major Walter Gall, the commanding officer, with saving several lives.
By the summer of 1951, Lieutenant Commander Lewis and his researchers had designed a new Marine armored vest, weighing about 8½ pounds, combining curved, overlapping doron plates with flexible pads of basket-weave nylon. This garment, according to the official description, was capable of “stopping a .45 caliber USA pistol or Thompson submachine gun bullet; all the fragments of the U.S. hand grenade at three feet; 75 percent of the U.S. 81mm mortar at 10 feet; and full thrust of the American bayonet.”
Only 40 vests were available for field tests in the summer of 1951. Lewis rotated them among as many wearers as possible in the three regiments selected for the test, the 5th Marines and the 23d and 38th regiments of the U.S. 2d Infantry Division. There was, as he saw it, a psychological question to be answered--would body armor win the acceptance of troops in combat? The hackneyed phrase “bullet-proof vest,” for instance, put the wearer in a class with the buyer of a gold brick. Nylon was associated in the minds of the men with alluring feminine attire rather than protection from shell fragments. Finally, there could be no denying that undesired weight had been added, that doron plates hampered movement to some extent, and that nylon pads were uncomfortably warm for summer wear.
Despite these drawbacks, Lewis found that troop acceptance was all that could be asked. The locale of the tests was the Inje area and the approaches to the KANSAS Line in June and early July. “By keeping these few vests almost constantly in use,” the Medical Service Corps officer commented, “the maximum amount of troop wear was obtained. Included in the wide sampling were company aid men, riflemen, BAR men, mortar (60mm) men, radio (backpack type) men--each carrying his basic weapon, ammunition load and a one-meal ration.”
When Lewis returned to Camp Lejeune, he reported “that body armor, protection of some type for the vital anatomic areas, is almost unanimously _desired by all combat troops_, particularly the combat veteran of several actual fire fights with the enemy.”[264]

Infantry body armor had at last made the transition from a dream to a reality. The M-1951 was put into production by a Philadelphia sportswear firm. And it was estimated that by the spring of 1952 nearly all Marines would be protected by the vest in combat.
Saving of American lives, of course, was a primary consideration. But there was a tactical as well as humanitarian advantage to be gained. For if body armor could reduce fatal and serious wounds by as much as 50 percent, as NMFRL researchers hoped, it would mean that a large percentage of the enemy’s best antipersonnel weapons had in effect been silenced.
_MAG-12 Moves to K-18_
There was no respite for 1st MAW while the 1st Marine Division remained in reserve. Operation STRANGLE was at its height, and interdiction flights called for nearly all the resources of Marine aviation during the summer of 1951.
Close air support missions were made secondary. This principle was upheld by Air Force Major General Otto P. Weyland:
I might suggest that all of us should keep in mind the limitations of air forces as well as their capabilities. Continuous CAS along a static front requires dispersed and sustained fire power against pinpoint targets. With conventional weapons there is no opportunity to exploit the characteristic mobility and fire power of air forces against worthwhile concentrations. In a static situation close support is an expensive substitute for artillery fire. It pays its greatest dividends when the enemy’s sustaining capability has been crippled and his logistics cut to a minimum while his forces are immobilized by interdiction and armed reconnaissance. Then decisive results can be obtained as the close-support effort is massed in coordination with determined ground action.[265]
[265] Quoted in James T. Stewart, _Air Power, The Decisive Force in Korea_ (Princeton, N. J.: Van Nostrand Company, 1957), 22–23.
Marine aviation officers, of course, would have challenged some of these opinions. But General Weyland insisted that in the summer and fall of 1951 “it would have been sheer folly not to have concentrated the bulk of our air effort against interdiction targets in the enemy rear areas. Otherwise, the available firepower would have been expended inefficiently against relatively invulnerable targets along the front, while the enemy was left to build up his resources to launch and sustain a general offensive.”[266]
[266] _Ibid._
The UN interdiction program was costly to the Communists. Yet it remained a stubborn fact that the enemy had not only maintained but actually increased his flow of supplies in spite of bombings that might have knocked a Western army out of the war. That was because CCF and NKPA troops could operate with a minimum of 50 short tons per day per division--an average of about 10 pounds per man. It was about one-fifth of the supply requirements for an equal number of U.S. troops.
Try as they might, the UN air forces could not prevent the arrival of the 2,900 tons of rations, fuel, ammunition, and other supplies needed every day by the 58 Communist divisions at the front.
The enemy during this period was increasing his own air potential. On 17 June the Fifth Air Force warned that the Communists had stepped up their number of planes from an estimated 900 in mid-May to 1,050 in mid-June. Their Korean airfields were being kept under repair in spite of persistent UN air attacks.
In June enemy light planes made night raids along the UN front lines and even into the Seoul area. VMF(N)-513 pilots, flying the nightly combat patrol over Seoul, had several fleeting contacts with these black-painted raiders. The Marines were unable to close in for the kill, since the opposing planes were nonmetal and difficult to track by radar. Soon, however, the VMF(N)-513 pilots had better hunting. On 30 June Captain Edwin B. Long and his radar operator, CWO Robert C. Buckingham, shot down a black, two-place PO-2 biplane. And on 13 July Captain Donald L. Fenton destroyed another.[267]

Despite the Air Force emphasis on interdiction, better close air support remained a major objective of the 1st MAW. One of the requirements was a shorter flying distance from air base to combat area. K-46, the MAG-12 field near Hoengsong, had qualified with respect to reduced flying time. Maintenance problems caused by the dusty, rocky runway of this primitive strip led to its abandonment. On 14 July the squadrons pulled back temporarily to K-1, and on the 26th MAG-12 withdrew its maintenance crews.
The Group’s new field was K-18, a 4,400-foot strip on the east coast near Kangnung and just south of the 38th Parallel. Situated only 40 miles behind the 1st Marine Division and on the seacoast, the new field seemed to be ideally located. The runway, reinforced with pierced steel planking, extended inland from a beach where water-borne supplies could be delivered, as at K-3.[268]

_The Division Back in Action Again_
Political causes had a good deal to do with the renewal of activity for the 1st Marine Division late in August 1951. Apparently the Communist armed forces had been given enough time to recuperate from their hard knocks in May and June. At any rate, the Red delegates walked out on the truce talks after falsely charging on 22 August that UN planes had violated the neutrality of the Kaesong area by dropping napalm bombs. Although the Reds were unable to show any credible evidence, the negotiations came to an abrupt end for the time being.[269]

On the 26th all Marine units received a Division warning that offensive operations were to be initiated in the immediate future. The effective strength, of the Division (including the KMCs) had been reported as 1,386 officers and 24,044 enlisted men on 1 August 1951. Attached to the Division at that time were 165 interpreters and 4,184 Korean CTC cargadores.
On the 26th the regiments were disposed as follows: the 1st Marines near Chogutan; the 5th Marines near Inje; the 7th Marines near Yanggu; and the 1st KMC Regiment at Hangye. Service units and the Division CP were located along the Hongchon-Hangye road in the vicinity of Tundong-ni.
The 11th Marines (-), with the 196th FA Battalion, USA, attached, constituted the 11th Marine Regiment Group, an element of X Corps artillery. Throughout the training period 2/11 remained under the control of the 1st Marine Division and 3/11 was attached to the 2d Infantry Division.
The 5th Marines, 7th Marines, and KMCs were alerted to be prepared to move up to the combat areas south and west of the Punchbowl on 27 August. The 1st Marines was to remain in Division reserve, and the 11th Marines reverted to parent control.[270]

It was only about a five hour motor march from Tundong-ni to the forward assembly area under normal road and weather conditions. But recent rains had turned roads into bogs and fordable streams into torrents. Bridges were weakened by the raging current in the Soyang, and landslides blocked the road in many places.
The 1st Marine Division was back in action again. But it would have to fight its first battles against the rain and the mud.
