Sorry about the late reply! Okay, so in 1941 the Japanese invaded the Philippines as a part of their larger effort to control all of Southeast Asia. It was drawn out, difficult fighting and the Americans and the British were both outnumbered and taken by surprise, so by early 1942, General MacArthur, the American commander, had withdrawn to the Bataan Peninsula. By this time, the ranks were depleted and men were dying not only of combat but also of disease and starvation on both sides. In other words, it was ugly. FDR didn't want MacArthur to die, so he ordered him out of the peninsula. The Japanese took the remaining Americans a couple months later. They expected to take around 25,000 prisoners but instead got 72,000 American and Filipino soldiers plus 26,000 civilians. The Japanese were woefully unprepared to manage this many POWs, and didn't hold people who got captured in high regard anyway, so there was little food and a lot of disorder as they were marched to a camp in Luzon. Around 600 Americans and 700 Filipinos were executed or starved on the way there. This was used as justification for some of the American military's more controversial decisions later in the war, for example, the firebombing campaign undertaken in 1944 (think about the fact that Japanese buildings were mostly paper and wood and you'll know why that was so controversial), and for some of the policies enacted on the home front, like the internment camps.
What resulted from the Bataan Death March?
