Beginning in August 1968, McCain was subjected to a program of severe torture. He was bound and beaten every two hours; this punishment occurred at the same time that he was suffering from heat exhaustion and dysentery. Further injuries brought McCain to “the point of suicide,” but his preparations were interrupted by guards. Eventually, McCain made an anti-U.S. propaganda "confession." He had always felt that his statement was dishonorable, but as he later wrote, "I had learned what we all learned over there: every man has his breaking point. I had reached mine." Many U.S. POWs were tortured and maltreated in order to extract "confessions" and propaganda statements; virtually all of them eventually yielded something to their captors. McCain received two to three beatings weekly because of his continued refusal to sign additional statements.
