The Filipino 'Terror Force' — Macario Peralta's Guerrilla Army

After the fall of Bataan, Major Macario Peralta organized a guerrilla army of over 30,000 fighters on the island of Panay in the Philippines. His forces kept 8,000 Japanese troops pinned down, recovered downed Allied airmen, and established a complete civil government with courts and schools while fighting. Peralta's intelligence network was so strong he had agents working in Japanese headquarters and knew of the 'Sho' defensive plan before the Japanese high command. His army was the largest Allied guerrilla force in the Pacific.
