Liberation: Marines in the Recapture of Guam
Part 5
From the end of the campaign to the end of the war in the Pacific, Guam served as a staging area for war dogs, of which 465 served in combat operations. Of the Marine Corps war dogs, 85 percent were Doberman Pinschers, and the rest mainly German Shepherds.
At the end of the Pacific War, the Marine Corps had 510 war dogs. Of this number, 491 were deprogrammed, a process that could take a year, and returned to their owners, given to their handlers, or returned to the Army, which had provided 41 to the Corps. Only four dogs could not be returned to their masters because, even after extensive retraining, they proved “incorrigible” and were considered to be unsafe for civilian life. ]
_Securing the Force Beachhead Line_
With the breakthrough at Fonte and failure of Takashina’s mass counterattack, the American positions could be consolidated. The 3d and 21st Marines squared away their holds on heights and the 9th Marines (July 27-29) pushed its final way up to Mount Alutom and Mount Chachao.
The most serious resistance to occupying the Mount Alutom-Mount Chachao massif and securing the Force Beachhead Line (FBHL) across the hills was a surprisingly strong point at the base of Mount Chachao. Major Donald B. Hubbard, commanding the 3d Battalion, 9th Marines (replacing Lieutenant Colonel Asmuth, wounded on W-Day), called down artillery, and, after the barrage, his Marines attacked with grenades and bayonets. They destroyed everything that stood in their path. When that fight was over, Major Hubbard’s battalion counted 135 Japanese dead. As the assault force pushed up these commanding slopes, the Marines could spot men of Company A of the 305th Infantry atop Mount Tenjo to the west. Lieutenant Colonel Carey A. Randall’s 1st Battalion, 9th Marines, then moved up and made contact with the Army troops. Originally, Mount Tenjo had been in the 3d Division zone, but General Bruce had wanted to get his men on the high ground so they could push ahead along the heights and not get trapped in the ravines. He also wanted to prevent the piecemeal commitment of his division and to preserve its integrity.
Conservative estimates put the Japanese dead as a result of the counterattack at 3,200 men. The loss of Takashina’s infantry officers, including General Shigematsu, who had commanded the _48th Independent Mixed Brigade_, was held to be as high as 96 percent. Takashina himself fell to the fire from a machine gun on an American tank as he was urging survivors out of the Fonte position and on to the north to fight again. With Takashina’s death, tactical command of all Japanese forces remaining on Guam was assumed by General Obata. He had only a few senior officers remaining to rally the surviving defenders and organize cohesive units from the shattered remnants of the battalions that had fought to hold the heights above the Asan-Adelup beaches.
All through the night of 28 July, Japanese troops trudged along the paths that led from Fonte to Ordot, finding their way at times by the light of American flares. At Ordot, two traffic control points guided men toward Barrigada, where three composite infantry companies were forming, or toward Finegayan, where a force of five composite companies was to man blocking positions. As he fully expected the Americans to conduct an aggressive pursuit on the 29th, General Obata ordered Lieutenant Colonel Takeda to organize a delaying force that would hold back the Marines until the withdrawal could be effected.
Contrary to the Japanese commander’s expectations, General Geiger had decided to rest his battle-weary troops before launching a full-scale attack to the north. The substance of his orders to the 3d and 77th Divisions on 29 July was to eliminate the last vestiges of Japanese resistance within the FBHL, organize a line of defense, and patrol in strength to the front. With capture of the beachhead line and its critical high ground and the annihilation of great numbers of Japanese, the turning point of the Guam campaign had been reached.
Yet, few Japanese had surrendered and those captured were usually dazed, wounded, or otherwise unable to resist. Almost all of the enemy died fighting, even when their lives were lost without sense or purpose. Still, a substantial number of troops from the _29th Division_ were still not accounted for.
General Geiger’s intelligence sections could only list about one quarter of the estimated soldier-sailor strength that had been on the island, and he needed to make certain that his rear was secure from attack before heading north after the enemy. Captured Japanese documents and prisoners of war, and sightings from aircraft, all indicated to Geiger that the Japanese had withdrawn to the north to better roads, denser and more concealing jungle, and commanding terrain for strongpoints.
To ensure that his rear area was not threatened, General Geiger had the 77th Division detail patrols to scour the southern half of Guam, repeating and intensifying the searches the brigade had made. These soldiers, as the Marines before them, found Guamanians everywhere, some in camps established by the Japanese, others on their farms and ranches. The natives, some surprised to see Americans so soon after the landings, reported the presence of only small bands of Japanese and often only single soldiers. It became increasingly evident that the combat units that remained were in the north, not the south. The best estimates of their strength ranged around a figure of 6,000 men.
Obata had expected a hasty pursuit, and set up strong rear guards to give time for his retreating forces to organize. Victory was no longer even a hope, but the Japanese could still extract a painful cost. General Geiger, who had a little time now, could give his troops a rest and move into attack positions across the width of the island. Strong and frequent patrols were sent out to find routes cross country and glimpse clues of enemy strength and dispositions.
Obata organized delaying defenses to include the southwest slopes of Mount Barrigada, midway across the island from Tumon Bay, and the little town of Barrigada itself, barely 20 houses. On all approaches to his final defensive positions near Mount Santa Rosa, in the northwest corner of the island, he organized roadblocks at trail and road junctions, principally at Finegayan and Yigo, and concealed troops in the jungle to interdict the roads which were the only practical approach routes to the northern end of the island. The Japanese commander felt sorely besieged, and as his notes later revealed: “the enemy air force seeking our units during daylight hours in the forest, bombed and strafed even a single soldier.” Perhaps even more damaging than the air attacks were artillery and naval gunfire bombardments brought down on men, guns, trenches, anything, by the Navy, Marines, and Army spotter planes which were constantly overhead.
_The Attack North_
III Corps’s Geiger knew Obata’s probable route of retreat and drew up a succession of objectives across the island which would incrementally seize all potential enemy strongpoints. Jump-off for the drive north was 0630 31 July with the 3d Marine Division on the left and the 77th Infantry Division on the right, dividing the island down the middle. The Marine zone would include the island capital of Agana, the Japanese airfield at Tiyan, Finegayan, and the shores of Tumon Bay. The 77th would have Mount Barrigada, Yigo, and Mount Santa Rosa in its zone. The 1st Marine Brigade relieved the 77th Division of the defense of the southern portion of the FBHL and would continue to patrol the southern half of Guam. As the Corps attack moved northward and the island widened, the brigade would eventually take part in the drive to the extreme north coast of the island.
The 3d Division reached Ordot in the center of its zone where Obata had directed some of his survivors. The 3d Battalion, 21st Marines, ran into them and one of their pillboxes, which the Marines thoroughly gutted. The Americans also accounted for 15 infantrymen and two light tanks which were the targets of M-1s and bazookas.
The honor of liberating Agana fell to the 3d Battalion, 3d Marines. The riflemen entered the town’s ruins treading carefully, sizing up the stark, dusty building walls for snipers. A few enemy riflemen emerged from behind concrete outcroppings then dropped back into eternity. The Japanese guards were stragglers, the wounded, or a few foolish enough to stay. In one house, a Marine opened a closet to reveal a Japanese officer, sword in hand. The Marine slammed the door, riddled it with an automatic rifle, and didn’t bother to look again. The once-beautiful old Plaza de Espana was in American hands 15 minutes after the town was entered. By noon it was secured.
The 1st and 2d Battalions, 3d Marines, moved along to the critical Agana-Pago Road. At 1350 the 21st Marines was right up there with them after the few engagements with pillboxes, snipers, and tanks. By 1510, Colonel Craig’s 9th Marines on the division’s right was partially across the road and seized the remaining portion of that highway in its sector on the next day. Hard-surfaced, with two lanes across the midriff of the island, the Agana-Pago Road would prove critical in winning the battle of Guam.
Leaving Agana and its historic rescue of the capital, the 3d Battalion, 3d Marines, under Major Royal R. Bastian, Jr., who had taken command when Lieutenant Colonel Houser was wounded on 22 July, moved on with relative ease. Before dusk the battalion had seized 1,400 yards of other critical roads and trails which led to strategic and defended strongpoints of Finegayan and Barrigada.
General Turnage got well within striking distance of the Tiyan airfield and the little town of San Antonio, on the 31st, but the next day, 1 August, his advance was seriously slowed by mines. It took the cool skill and slow and steady hands of the bomb disposal specialists of the 25th Naval Construction Battalion and the 19th Marines’ engineers to reduce those obstacles.
Students of the battle and those who were there consider the taking of the cross-island Agana-Pago Road as a major factor in guaranteeing the success of the drive northward. Its capture solved a host of logistic problems, for the 77th particularly. The Army division, for example, had no roads heading north initially in its zone of advance and needed such a road over which it could supply its troops as they came down out of the hills and cut their way through the jungle. Frontline troops in the Army zone were soon running low on supplies, especially water. General Bruce promised his people a hot breakfast as soon as they and the Marines could give him the road. Trucks were soon thick on the road even while SeaBees and engineers were enlarging and repairing it.
The 77th had moved out on schedule just after daylight on 31 July, with the 307th Infantry in the advance, followed by the 305th. As was the situation facing the 3d Division, enemy resistance to the Army advance was negligible. Within two hours, both Army regiments had secured the cross-island road in their zones. The 307th rescued 2,000 Guamanians in the detention camp at Asinan. Unopposed, the 77th by noon of 1 August was across the Pago River. Residents of the area said the Japanese had left in a hurry for Barrigada, a destination where III Corps intelligence already anticipated the enemy would hold up. The jungle-covered mountain there, 674 feet high, dominated the area.
General Bruce assigned the capture of Barrigada to the 307th. It was to maintain contact with the 3d Marine Division on the left and push through the town, then continue about a mile to seize Mount Barrigada. The 305th to the right of the 307th would attack in the same direction east of the town and Barrigada mountain and protect to the coast. The town was in a clearing fully swept with defensive machine gun fire. In the same clearing was a much-desired well. Its capture meant the world to the parched troops.
At 0630, 2 August General Bruce dispatched a dozen tanks of the 706th Tank Battalion on a reconnaissance. As the “recon” armor turned into Barrigada town, the enemy opened up with a torrent of fire. The determined Japanese fiercely resisted the 307th when it reached the town and were equally determined to stop the 305th on the right as that regiment’s assault companies tried to outflank the town. Repeated tank attacks and heavy artillery support netted only a few yards at a time, but the soldiers kept advancing and by 4 August, the 77th Division held the town, or what was left of it, its precious well, and the crest of the mountain.
Captured documents and interviews with prisoners again left little doubt that the 77th Division’s major obstacle would be rugged, heavily crevassed, and jungled Mount Santa Rosa. It is six and a half miles northeast of Barrigada and a short distance from the ocean on the east coast.
First to be addressed on the way were well-armed outposts like Finegayan and Yigo. Each promised casualties, blood, and delay. General Geiger employed the 77th to reduce Yigo and take Santa Rosa, and left the capture of Finegayan and the rest of northern Guam principally to the 3d Marine Division. He brought up General Shepherd’s brigade to assist in the final drive. To protect the Force Beachhead Line, care for the Guamanians, and hunt down enemy stragglers in the south, General Geiger tasked the 1st Battalion, 22d Marines; the 7th Antiaircraft Artillery Battalion; and the 9th Defense Battalion, all under Lieutenant Colonel Archie E. O’Neil, who commanded the 9th.
Before moving on, the brigade had aggressively sought out Japanese holdouts, brought the fearful Guamanians into friendly compounds, and provided security for those who chose to remain in their own homes and again work their own ranches. As late as 2 August, 4th Marines’ patrols approaching Talofofo Bay on the southeast coast, came across some 2,000 natives, still apprehensive of the Japanese, who were directed to a compound which promised safety and at least minimum comforts. The Guamanian people in their own residential and farm areas could, however, still readily call upon the civil affairs sections for food, protection, medicine, and shelter. Such civil care was integral to the American occupation and was controlled by Marine General Larsen, who would head the garrison force as soon as the island was again under the American flag.
During the night of 2-3 August, the 12th Marines delivered 777 rounds of harassing and interdictory fire on the roads and trails the division would encounter around Finegayan. At 0700 on 3 August, the 3d and 9th Marines moved in assault well past the Tinyan airfield. Then, about 0910 the 9th encountered a block at the cross roads approaching Finegayan village. The situation and terrain favored the Japanese with excellent fields of fire. After the Japanese position was finally overrun with tanks, Lieutenant Colonel Carey Randall, commanding 1st Battalion, 9th Marines, said that these defenses were the toughest he had faced on Guam.
That contest for Finegayan was the last major battle for the 3d Division on Guam. The Japanese made it something to remember. A 3d Division armored reconnaissance patrol headed for Ritidian Point on the northernmost point of the island ran into Japanese defenses located on the Finegayan trails bristling with antitank weapons and artillery pointed in the direction of the patrol. The Americans were surprised and bruised, did the Japanese some harm, but sensibly cancelled the mission.
The Japanese were plenty feisty at Finegayan, and in a telling thrust dispatched two medium tanks which skirted the crossroads of the 9th Marines at Junction 177 and went up the Finegayan-Mount Santa Rosa Road. Impervious to Marine fire, the tanks shot up the area and got away. Another tank force of undetermined size then rumbled down under cover of a mortar barrage and it looked like the beginning of a counterattack. Artillery stilled that Japanese effort. The enemy tanks were driven off but survived to reappear again another day.
It was in one of those typical sudden enemy attacks around Finegayan that Private First Class Frank P. Witek, with automatic rifle and grenades, raced ahead of his own tanks to destroy an eight-man Japanese position which was holding back elements of his 1st Battalion, 9th Marines. He succeeded, but was killed. He was posthumously awarded the Medal of Honor.
_Beginning of the End_
On 4 August, the new frontlines and scheme of maneuver were being set up to keep pressure on General Obata and his holdouts, and make a place for General Shepherd and his brigade. During the afternoon, the brigade reached its northern assembly area and General Shepherd set up his CP near San Antonio. In the final advance north, the brigade would be on the left with its inland flank within a mile of the western beaches. The 3d Division would be in the center deploying its units on a three-regiment front which would swerve to the east to take in the whole northern end of the island and as well support the 77th Division.
The Japanese now faced an overwhelming number of attack forces. And there would be plenty of help from the sea and from the air. General Bruce’s soldiers made the principal corps drive to destroy the remaining Japanese and attacked Mount Santa Rosa. Priority of fires of corps artillery, air support, and ships’ gunfire was now given to the Army. These new arrangements were to take effect on 7 August.
Making new strides to end the campaign, the 3d and 21st Marines progressed handily but the 9th Marines kept running into dense jungle that was such a tangled mess that tanks passed each other 15 feet apart without knowing the other was there. The division accelerated its advance in battalion columns. On 6 August, it had progressed 5,000 yards along the road to Ritidian Point, the end of the island and the end of the battle for Guam. As that evening fell, the 3d Division was in visual contact with the 77th Infantry Division, wherever the all-encompassing jungle allowed.
Meanwhile, heavy Seventh Air Force bombing as well as artillery and naval shelling of enemy areas had been going on for days. Night fighters were now assigned to support the advance, so even darkness afforded the Japanese no protection. By that same 6 August, the defense line that General Obata had set across Guam had been shattered and overrun. Only isolated pockets now existed before Santa Rosa.
No American commander could say on 7 August when the fight for Guam would be over. General Bruce in his attack first to Yigo and then Santa Rosa would have a relatively fresh regiment, the 306th, which had come up from the south where it had patrolled with the brigade. It was in contact with the 9th Marines on the division boundary. Colonel Douglas C. McNair, 77th Division chief of staff, was there, too, seeking a site for a division CP and was killed by a sniper. Colonel McNair’s father, Lieutenant General Leslie J. McNair, was killed in France 12 days earlier during an American bombing raid.
The attack on Mount Santa Rosa began at noon, 7 August. Behind the rumble of artillery and rattle of tanks, answered in kind by the enemy, the 77th took Yigo, the door to Santa Rosa, and continued General Bruce’s wheeling maneuver. Bulldozers blazed trails, and tanks and infantry overran machine gun positions. The 77th was dug into positions on the night of 7-8 August ready for the final attack on the mountain. The expected big Japanese counterattack still did not come. The rapid advance of the Americans accompanied by heavy artillery support likely forestalled that forelorn hope.
