alerted Japanese contingent situated across the Cabu River. Pajota had earlier sent a demolitions expert to set charges on the unguarded bridge to go off at 19:45. The bomb detonated at the designated time, and although it did not destroy the bridge, it formed a large hole over which tanks and other vehicles could not pass. Waves of Japanese troops rushed the bridge, but the V-shaped choke point created by the Filipino guerrillas repulsed each attack. One guerrilla, who had been trained to use the bazooka only a few hours earlier by the Rangers, destroyed or disabled four tanks that were hiding behind a clump of trees. A group of Japanese soldiers made an effort to flank the ambush position by crossing the river away from the bridge, but the guerrillas spotted and eliminated them. At 20:15, the camp was secured from the Japanese and Prince fired his flare to signal the end of the assault. No gunfire had occurred for the last fifteen minutes. However, as the Rangers headed towards the meetup, Cpl. Roy Sweezy was shot twice by friendly fire, and later died. The Rangers and the weary, frail, and disease-ridden POWs made their way to the appointed Pampanga River rendezvous, where a caravan of 26 carabao carts waited to transport them to Platero, driven by local villagers organized by Pajota. At 20:40, once Prince determined that everyone had crossed the Pampanga River, he fired his second flare to indicate to Pajota and Joson's men to withdraw. The Scouts stayed behind at the meetup to survey the area for enemy retaliatory movements. Meanwhile, Pajota's men continued to resist the attacking enemy until they could finally withdraw at 22:00, when the Japanese forces stopped charging the bridge. Joson and his men met no opposition, and they returned to help escort the POWs. Although the combat photographers were able to shoot images of the trek to and from the camp, they were unable to use their cameras during the night-time raid, as the flashes would indicate their positions to the Japanese. One of the photographers reflected on the nighttime hindrance: "We felt like an eager soldier who had carried his rifle for long distances into one of the war's most crucial battles, then never got a chance to fire it." The Signal Corps photographers instead assisted with escorting the POWs out of the camp. Trek to American lines By 22:00,
