Ciriaco Ladines was under the command of Lt. Col. Bernard Anderson, one of the dozens of U.S. military personnel who did not surrender with the fall of Bataan and instead took to the hills to mount a guerrilla resistance movement. Anderson formed the “Anderson Guerrillas” in the Tayabas Province south of Manila. He commanded 7,000 men and his XO was Col. Jaime Manzano.
