He was recalled to active duty as commander of the U.S. army forces in the far east. A series of disasters followed, beginning with the destruction of his air forces on December 8. 1941, and the invasion of the Philippines by the Japanese. His forces had to withdraw from Bataan.
The only thing I can think of is his change of strategy in the middle of the invasion of the Philippines to abandon the fighting opposing the invading forces to, instead, withdraw to the Bataan peninsula.
