By 23 October the 383d Infantry, less the 1st Battalion, had crossed the Guinarona River and established a position west of Pikas. Having been ordered by General Bradley to hold this position, the regiment limited its activities to patrolling. While awaiting orders to advance, Colonel May decided to give battle training to various units by sending them out on patrolling missions to observe the enemy.[42] Tabontabon and San Victor were assigned to the 3d Battalion commander as a training mission for one of his companies, while San Vicente Hill was assigned to the 2d Battalion commander for the same purpose. Tabontabon was a key point, since it was one of the main 16th Division supply centers.
Company K, which had been selected by the 3d Battalion commander for the first mission, sent patrols into the Tabontabon—San Victor area on the afternoon of 24 October. The patrol sent to Tabontabon found that the 9th Infantry Regiment had extensively fortified the barrio. There were deep foxholes and machine gun emplacements dug in under the houses. None of the positions appeared to be occupied, but at the end of the town the patrol saw approximately twenty-five Japanese preparing their evening meal. Tabontabon was a fairly large barrio on the Guinarona River, with several blocks of shops and houses, including a church and several two-story buildings, the axis of the town running east and west.
On the basis of information brought by the patrol, it was decided to have Company K move out the following morning to seize Tabontabon. At 0645 on 25 October Company K, reinforced, advanced and at 0730 took covered positions 200 yards east of the barrio. Under the plan for attack the 1st Platoon was to approach the northeastern edge of the village by a covered route, and await the completion of an artillery concentration scheduled for 0800. After the artillery preparation a squad from the platoon was to enter and reconnoiter for possible enemy positions. At the same time, the 2d Platoon, with a similar mission, was to enter Tabontabon from the southeast side. The 3d Platoon was to be prepared to support the action of either the 1st or the 2d. Machine guns and mortars were placed in such a way as to give direct support to both platoons.
Because of unexplained communication difficulties, the artillery did not deliver its scheduled fire at 0800. Each platoon, however, sent a squad into Tabontabon. As soon as advance elements of both platoons entered the town they came under intense rifle and mortar fire from enemy positions under the houses. It was obvious that the Japanese had heavily reinforced the barrio during the night. The reinforcements consisted of a battalion from the 9th Infantry Regiment.[43]
The rest of the 1st and 2d Platoons came up and a fire fight ensued. The 3d Platoon was sent in at 1000 to support the 1st Platoon, and in response to a request for reinforcements, a rifle platoon from Company I was brought up at 1040. The commanding officer of Company K advised the 3d Battalion by radio that he could take Tabontabon with an additional rifle company but could not do so with his present force without suffering heavy casualties. The battalion commander ordered him to withdraw. The withdrawal, under supporting fire from the 3d Platoon, Company K, the platoon from Company I, and mortar and machine gun fire from the weapons company, was successfully accomplished at 1155. At 1240 Company K rejoined the battalion.
General Bradley ordered the 383d Infantry to direct the patrols of the 3d Battalion elsewhere, since the 382d Infantry had been assigned the mission of securing Tabontabon. During the forthcoming attack the 383d Infantry was to protect the flank of the 382d, whose 2d and 3d Battalions were to launch a co-ordinated attack on the town. On 26 October the 2d Battalion of the 382d Infantry moved west and established contact with the 3d at 1200. After an artillery concentration had been placed on the town the two battalions moved out.
By 1600 they had forded the shoulder-deep Guinarona River under heavy enemy fire and had reached the edge of Tabontabon. As the battalions slowly pushed their way to the outskirts of the barrio, they came under heavy fire. Elements of the 9th Infantry Regiment had dug in under the houses, and connecting trenches honeycombed the streets from one strong point to another. At twilight, after heavy artillery fire, the enemy launched a strong counterattack which forced the battalions to withdraw to the river bank, where they established perimeters for the night.[44] Until midnight, mortar fire from the 9th Infantry Regiment fell in the 2d and 3d Battalion areas.
At 2100 the 96th Division artillery commenced firing on the town and continued to fire throughout the night. The 1st Battalion, less Company B which had been left at Aslom to guard supplies, had by now joined the rest of the regiment. At 1000 on 27 October the 382d Infantry launched a co-ordinated attack against Tabontabon with the 2d and 3d Battalions. As Companies I and K of the 3d Battalion started to wade the Guinarona River, Colonel Dill, the regimental commander, called to the men to follow him and then dashed across the bridge, which was swept by enemy rifle fire. The 3d Battalion followed him over the bridge and to the southeast corner of the barrio.[45] The troops met considerable opposition from elements of the 9th Infantry Regiment who were hidden in the tall cogon grass. After a short fire fight the two battalions worked their way slowly through the western portion of the town and then advanced northwest. Although they met fire from several pillboxes, there was no organized resistance. Night perimeters were set up about a mile northwest of Tabontabon with the 3d Battalion on the left side of the road and the 1st Battalion on the right.[46]
The 2d Battalion, which had hit the center of the town, encountered stiff and determined opposition. Company F proceeded cautiously down one street as Company G went through the middle of the second block on its right. The Japanese had riflemen and machine guns under the houses and on the second floors of the large buildings. By noon the two companies had worked their way through to the northern edge of the town, where they encountered the enemy entrenched in force.
The Japanese had placed machine guns to cover the exits from the barrio. The guns were aimed down each street and so placed that each gun was protected by another. Since in Company G men were dropping from heat exhaustion, Company E was sent in to relieve Company G. At the same time, the 2d Platoon of the Cannon Company moved forward, but its howitzers were unable to direct their fire effectively. Late in the afternoon, since it had become apparent that the 2d Battalion would not be able to secure the town before nightfall, the troops were called back to the center of the town, where the 2d Battalion set up its night perimeter.[47]
