As Company C started its withdrawal, the enemy moved forward. Keeping well concealed, the Japanese edged forward and laid down a heavy volume of rifle, machine gun, and mortar fire on the troops, but the holding force stopped the advance. An intense fire fight broke out in which both sides suffered many casualties. The Americans held on grimly.

At 1530 Colonel Finn ordered the 3d Battalion, 32d Infantry, to move to the left of the 1st Battalion, but the swamps and heavy foliage made progress slow. By 1630 the 3d Battalion was 600 yards to the left rear of the 1st Battalion.

During the fight Colonel Finn went forward. Grasping the seriousness of the situation, he ordered the 1st Battalion to withdraw to San Pablo airstrip and sent one platoon of the 3d Battalion to assist the 1st Battalion in its withdrawal. The rest of the 3d Battalion was to protect the withdrawal of the 1st. The troops rapidly carried out the orders and withdrew to the airstrip. The 2d Battalion, released from division reserve that evening, moved up on line with the 3d Battalion. The 32d Infantry formed a defensive perimeter for the night.[29]

During the day the 2d Battalion, 32d Infantry, captured a Japanese private, Isamu Nakamaru, who had been a mechanic with the 7th Independent Tank Company. He informed his captors that his company originally had eleven tanks. Eight of these were lost in the action near Julita; the others were at Buri but were out of commission. All the tanks were obsolete and had been used mainly to clear and roll the airstrips.[30]

On the morning of 25 October the 49th Field Artillery Battalion fired concentrations from 0800 to 0830 in front of the 32d Infantry and covered an area of 400 yards on each side of the Buri airstrip.[31] At 0700 the 3d Battalion moved to the right and in front of the 1st. The 32d Infantry was to move out at 0830 with the 2d and 3d Battalions abreast, each battalion to be preceded by a platoon of tanks.

At 0830 the battalions attacked, both advancing 1,500 yards before they encountered any serious obstacle. The 2d Battalion on the right ran into the system of bunkers that protected the Buri airstrip. The 3d Battalion halted and waited for the 2d to overcome the bunkers and move forward. Though an antitank gun was brought up to fire on the bunkers, two futile attacks were launched against them and it became apparent that the 2d Battalion would be considerably delayed. Colonel Finn therefore ordered the 3d Battalion to advance and secure the edge of the Buri airstrip, and, with its reserve company, to close the gap thus created.

Colonel Finn also ordered the 1st Battalion to move closer to the right flank of the 3d and prevent an enemy envelopment. Meanwhile, strong patrols which the 3d Battalion had sent to within 300 yards of the airstrip reported that they had encountered only one strong point in the 3d Battalion’s zone of advance. In order that the 3d Battalion could be certain it was moving in the direction of the airstrip, Colonel Finn requested an artillery liaison plane to drop a flare over the southwest edge of the airfield. After this was done the battalion resumed its attack and at 1700 reached the edge of the airstrip. Fortunately the battalion immediately went into a defensive position, for at 1715 a sharp enemy assault had to be repulsed with machine gun and rifle fire.[32]

Meanwhile the 2d Battalion probed at the bunkers located at the edge of the heavy woods on the northern fringe of the Buri airfield. These defenses consisted of three bunkers connected by an elaborate system of trenches and spider holes. Both flanks of the 2d Battalion received machine gun fire, which became heavier upon any attempt to carry out an enveloping movement. Under cover of fire from American heavy machine guns, the 2d Battalion withdrew its wounded. It then formed a night perimeter and waited for heavier supporting weapons to be brought up.

On the following day the 2d Battalion was to move from its night perimeter on a 400-yard front and secure the western end of the airstrip. The 3d Battalion, 32d Infantry, was to follow the 1st Battalion and protect the regiment from an attack from the north. Each of the assault battalions was to have attached a platoon of medium tanks and a platoon from the Cannon Company.[33]

On the morning of 26 October, the 49th Field Artillery Battalion for ten minutes concentrated its fire for 500 yards on each side of the airstrip. At 0800 the 32d Infantry attacked. The artillery fire had been effective, and the 2d Battalion knocked out the pillboxes that had stopped its advance the previous day. Aided by tanks, the battalion was able to advance 700 yards along the south side of the airstrip by 1700.
