McCain spent six weeks in the hospital while receiving marginal care.[33] By then having lost 50 pounds (23 kg), in a chest cast, and with his hair turned white,[33] McCain was sent to a different camp on the outskirts of Hanoi[39] in December 1967, into a cell with two other Americans who did not expect him to live a week.[40] In March 1968, McCain was put into solitary confinement, where he would remain for two years.[41]
In mid-1968, John S. McCain, Jr. was named commander of all U.S. forces in the Vietnam theater, and the North Vietnamese offered McCain early release[43] because they wanted to appear merciful for propaganda purposes,[44] and also to show other POWs that elite prisoners were willing to be treated preferentially.[43] McCain turned down the offer; he would only accept repatriation if every man taken in before him was released as well. Such early release was prohibited by the POW's interpretation of the military Code of Conduct: To prevent the enemy from using prisoners for propaganda, officers were to agree to be released in the order in which they were captured.[33]
In August 1968, a program of severe torture began on McCain.[45] He was subjected to rope bindings and repeated beatings every two hours, at the same time as he was suffering from dysentery.[33][45] Further injuries led to the beginning of a suicide attempt, stopped by guards.[33] After four days, McCain made an anti-American propaganda "confession".[33] He has 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."[46][47] Many American POWs were tortured and maltreated in order to extract "confessions" and propaganda statements, with many enduring even longer and worse treatment;[48] virtually all of them eventually yielded something to their captors.[49] McCain subsequently received two to three beatings weekly because of his continued refusal to sign additional statements.[50]
