 About 4,000 of the 11,000 American and Filipino prisoners of war from the island were marched through the streets of Manila to incarceration at Fort Santiago in Intramuros and Bilibid Prison in Muntinlupa, Rizal, which had become Japanese camps.With the fall of Corregidor, Filipino and U.S. forces under U.S. command surrendered.After the surrender, thousands of Filipinos formerly under U.S. command (especially the former Visayan-Mindanao Force, which had seen little combat) evaded Japanese confinement and hid in the jungle.
