McCain on lower right
In August of 1968, a program of vigorous torture methods began on McCain, using rope bindings into painful positions and beatings every two hours, at the same time as he was suffering from dysentery.[84][79] Teeth and bones were broken again, as was McCain's spirit; the beginning of a suicide attempt was stopped by guards.[79] After four days of this, McCain signed and taped[94] an anti-American propaganda "confession" that said, in part, "I am a black criminal and I have performed the deeds of an air pirate. I almost died, and the Vietnamese people saved my life, thanks to the doctors."[79] He used stilted Communist jargon and ungrammatical language to signal that the statement was forced.[89]. Source
