A few days after the rescue, the Japanese in full force, led by the escaped Sadaaki Konishi, returned to Los Baños. Upon seeing that there were no POWs in sight, the Japanese turned their wrath on the remaining civilians in town who had failed to heed the warning from the guerrillas to leave. With the help of the pro-Japanese Makapili, the Japanese massacred some 1,500 men, women and children, and burned their homes, as well as those in the adjacent towns suspected of collaborating with the liberators. Konishi was tried for his war crimes after the war and hanged.
