Thousands of Filipino soldiers and hundreds of American soldiers died of their wounds on the infamous Bataan Death March. Others were brutally murdered by Japanese troops when they could not keep up with the pace. The men of the Bataan Death March passed by the main gate of Clark Air Base, as the soldiers followed the direction of the railway tracks north. Later, following their initial incarceration at Camp O'Donnell, most American POWs were moved to Cabanatuan, while their Filipino comrades remained at Camp O'Donnell.
