Los Baños Internment Camp

The Raid on Los Baños (Filipino: Pagsalakay sa Los Baños) in the Philippines, early Friday morning on 23 February 1945, was executed by a combined United States Army Airborne and Filipino guerrilla task force, resulting in the liberation of 2,147 Allied civilian and military internees from an agricultural school campus turned Japanese internment camp. The raid has been celebrated as one of the most successful rescue operations in modern military history, although it led to the massacre of 1500 Filipino civilians in retaliation. It was the second precisely-executed raid by combined U.S.-Filipino forces within a month, following on the heels of the Raid at Cabanatuan at Luzon on 30 January, in which 522 Allied military POWs had been rescued.
