For anyone to disparage any US soldier that was in the Philippines and was captured is disgusting. They fought a brilliant retreat back to the Bataan peninsula and held out for months, until their supplies ran out. Just as with the Marines on Wake at the beginning of the war who fought extremely well, sank two Japanese destroyers with a handful of 5" guns on Wake, and only surrendered to vastly superior numbers of enemy that had plentiful supplies and ammunition two weeks later.
The US forces at Bataan beat the hell out of the Japs until they ran low on supplies and ammunition.
MacArthur left because he was ordered to leave. His capture and/or death would not have made any difference re the Bataan death march.
