Why was Douglas MacArthur forced to leave Bantaan?

Answer 1

he talked too much about military affairs in Korea which was against President Truman's orders
Arrogance, accompanied by MacArthur's statement that Red China wouldn't enter the war...and they did.

Answer 2

MacArthur actually had his headquarters on the small island of Corregidor, off the coast of the Bataan peninsula. Corregidor held out for another month after the Japanese overcame the defenders on the Bataan peninsula. But by that time MacArthur was in Australia. He was ordered to make this escape by President Roosevelt. MacArthur was a famous man already. He had spent four years as Chief of Staff of the US Army (commanding general) from 1931-35. This was twice the two years it was usual for a man to hold the highest position in the US Army. He had "retired" after that but had taken a job as a military adviser to the Philippine Commonwealth, and was a Field Marshal in the Philippine service. He was recalled to active duty in the US Army in the summer of 1941, as war clouds gathered. Roosevelt was concerned about the Propaganda value the Japanese would receive from making a former commanding general of the US Army a prisoner. To emphasize that the government stood behind MacArthur, he was awarded the Medal of Honor, an honor which would hardly be justified by the mistakes he made when the Japanese first attacked the Philippines.
