"I think it was on the fourth day [after being shot down] that two guards came in, instead of one. One of them pulled back the blanket to show the other guard my injury. I looked at my knee. It was about the size of a football . . . when I saw it, I said to the guard, 'O.K., get the officer' . . . an officer came in after a few minutes. It was the man that we came to know very well as 'The Bug.' He was a psychotic torturer, one of the worst fiends that we had to deal with. I said, 'O.K., I'll give you military information if you will take me to the hospital.'"
McCain had his wounds treated in one of their military hospitals where they treated their own officers, he received treatment not available for other U.S. prisoners of war.
Thanks. That confirms my recollection.
