From Geoffrey Perret's There's a War To Be Won ...
"The 11,000 men who surrendered on Corregidor were, they soon discovered, not considered prisoners of war by their captors. Instead, they were treated like a low form of life, on a par with parasites and vermin. [Japanese Lt. Gen. Masaharu] Homma [commander of the main Japanese invasion force in the Philippines] threatened to murder all of them unless [Army Lt. Gen. Jonathan M.] Wainwright [commander of U.S. forces in the Philippines] ordered subordinate commanders throughout the Philippines to surrender themselves and their men.
"The Japanese put Wainwright in front of a microphone at a Manila radio station. [Army Chief of Staff, General George C.] Marshall wanted someone who knew Wainwright well to listen in and tell him if the broadcast was genuine or a Japanese hoax. J. Lawton Collins, recently appointed commander of the 25th Infantry Division in Hawaii, had served for three years under Wainwright and admired him unreservedly. Collins listened to the broadcast as Marshall requested.
"There was no doubt about it. That was Skinny Wainwright, his voice dulled by exhaustion, choking with emotion as he ordered his men to surrender. That was Skinny Wainwright, with his limp from a bad riding accident, always leaning on a stick when not in the saddle. That was Skinny Wainwright, humiliated, defeated, heading for captivity and possibly a cruel death. Collins sat by his radio that balmy evening in Hawaii, his round, boyish face wet with the tears shed for his friend."
