I was talking to my Father in Law, who was a boy when the Japanese came thru Singapore, after storming through Malaysia. He recalled seeing Japanese soldiers riding Bicycles.
He told me the soldiers waved the Malaysion's off...they were searching for the Chinese. Point is-they were dead-set on their mission, and were not going to let gasoline, or the lack of it stop them.

As for MacArthur, I think he was a good soldier, nothing more-nothing less, and he should have been leashed when he went rogue by taking it upon himself to speak for the United States.
