In April 1942, over 70,000 American and Filipino troops surrendered to the Japanese after being starved and diseased while defending Bataan Peninsula in the Philippines. The Japanese forced the prisoners of war to march over 70 miles to Camp O'Donnell with little food or water. Thousands of prisoners died along the way from execution, disease, or starvation as the Japanese guards beat and shot those who fell behind. Upon arrival at the camp, more prisoners perished due to continued maltreatment and unsanitary conditions.
