During the night the 361st, 363d, and 921st Field Artillery Battalions delivered harassing fires on the positions of the 9th Infantry Regiment on Labiranan Head.[14] The following morning, Captain Young’s force rejoined the 1st Battalion, 383d Infantry. The 921st Field Artillery Battalion continued to pound the enemy emplacements until 1200 and then supported the attack as the 1st Battalion, 383d Infantry, with Companies A and C as lead companies, moved up the slopes of Labiranan Head. The antitank platoon of the 1st Battalion set up its 37-mm. guns in a position from which it could rake the south side of Labiranan Head from the river and support the advance of Company C on the left. The platoon knocked out four pillboxes and two machine guns and then directed fire on the enemy 75-mm. guns. Companies A and C pushed aside the Japanese and at 1630 reached the crest of the hill, their objective. They immediately dug in, consolidated the position, and then formed a night perimeter from which the entire beach area from San Roque to Dulag could be observed.[15]
At 1930 the Japanese centered a counterattack on Company A on the right flank of the 1st Battalion, 383d Infantry. A combined concentration from the 921st, 361st, and 363d Field Artillery Battalions repelled this assault.[16] While Labiranan Hill was being secured, a force consisting of the 3d Platoon, Company C, the 1st Platoon, Company D, 763d Tank Battalion, the 1st Platoon, Cannon Company, and the battalion Antitank Platoon pushed along Highway 1, secured San Roque, and set up a roadblock.[17] From the 23d to the 26th of October the 1st Battalion, 383d Infantry, patrolled the Labiranan Hill—San Roque area and protected the right flank of the 96th Division as the rest of the division slogged through swamps and rice paddies to the south.
Battling the Swamps
At 0840 on 21 October the 2d and 3d Battalions, 383d Infantry, which were to go in a northwesterly direction around Catmon Hill and isolate the Japanese force on the hill, moved out westward. They advanced through swamps and rice paddies but met no Japanese during the day. At 1640, when they established a night perimeter, the 2d Battalion was 300 yards north of Tigbao and the 3d Battalion with the regimental command group was 1,100 yards northeast of the barrio and south of Catmon Hill.[18]
The 382d Infantry, while protecting the left flank of the 96th Division, was to advance rapidly into the interior and seize Tigbao.[19] During the night of 20–21 October artillery fire from an unknown source fell in the sector of the 2d Battalion, killing three men and wounding eight others. At 0800, on 21 October, the 2d Battalion, 382d Infantry, moved out, followed at 0812 by the 3d Battalion. These troops, like the 2d and 3d Battalions of the 383d Infantry, were confronted with waist-deep swamps which made the going slow and arduous. The 3d Battalion, 382d Infantry, immediately after moving out, ran into enemy pillboxes constructed of coconut logs and defended by machine guns and riflemen. At first the troops bypassed the pillboxes but at 1030 Company K went back and wiped them out. In addition to the morass through which the troops were moving, numerous empty pillboxes slowed up the advance, since each of them had to be checked.[20] At 1430, because there was a gap between the 2d and 3d Battalions, Colonel Dill committed the 1st Battalion to close the line. The battalions then advanced abreast and kept lateral contact with the 2d and 3d Battalions of the 383d Infantry on their right. At 1630, when the battalions established their night perimeters, they were far short of their objective.[21]
At 1745 Colonel Dill directed all of the battalions of the 382d Infantry to move out at 0800 on 22 October—the 1st Battalion was to capture Tigbao and Bolongtohan and then push on to Hindang; the 2d Battalion was to proceed toward Anibung; and the 3d Battalion, on the right of the 1st Battalion, was to proceed to the northwestern edge of Bolongtohan.[22]
Since it was known that the Japanese were strongly entrenched on Catmon Hill, General Bradley had decided to bypass the hill temporarily. His plan called for the 2d and 3d Battalions of the 383d Infantry to envelop Catmon Hill from the south and then move north to make contact with the 24th Division at Tanauan.[23] On the morning of 22 October, Colonel May of the 383d Infantry asked General Bradley for permission to attack Catmon Hill from the south with his 2d and 3d Battalions. General Bradley refused the request and ordered Colonel May to continue the enveloping movement he had started on 21 October.[24] Later on that morning, therefore, the 2d and 3d Battalions, 383d Infantry, moved out north-northwest. Encountering a deep swamp at 1130, the troops turned northwest. This move did not materially help the situation, since they found that they had exchanged the swamp for rice paddies. The advance units reached Anibung at 1630 without encountering any Japanese. By 1800 all units had closed in on the vicinity of Anibung and set up a night perimeter 400 yards north of the barrio.
Few supplies had been brought forward because the vehicles of the battalions had advanced only 200 yards when they bogged down. The troops hand-carried their weapons and communications equipment, while civilians with about eight carabaos[25] helped carry the supplies. In the transportation of supplies forward, ammunition was given priority over rations and water, even though the supply of the latter items, which had been issued to the troops before landing, was nearly exhausted. The men made free use of coconuts for food and drink.[26]
At 0800 on 22 October the three battalions of the 382d Infantry moved out. By 0900 the 1st and 2d Battalions had pushed through Tigbao, whereupon the regimental commander changed the orders for the day. He ordered the 2d Battalion to take Bolongtohan, the 1st Battalion to seize Canmangui, and the 3d Battalion to go into reserve.[27]
The 1st and 3d Battalions of the 382d Infantry made contact with each other at 1152. When patrols from the 1st Battalion did not find any Japanese at Canmangui, the battalion proceeded toward Bolongtohan. Upon nearing Mati, the 1st Battalion encountered an entrenched position of the enemy and by outflanking the position was able to knock it out. The Japanese fought a delaying action and withdrew during the afternoon. At 2000 the battalion formed its night perimeter at Mati. The other battalions of the regiment encountered no Japanese during the day’s progress inland, and formed their night perimeters at 1800—the 2d Battalion 800 yards east of Bolongtohan and the 3d Battalion 500 yards southeast of Tigbao. During the day the 382d Infantry had pushed forward approximately 2,000 yards.[28]
