And they broke his left arm again during interrogation.
I pulled the ejection handle, and was knocked unconscious by the force of the ejection—the air speed was about 500 knots. I didn't realize it at the moment, but I had broken my right leg around the knee, my right arm in three places, and my left arm. I regained consciousness just before I landed by parachute in a lake right in the corner of Hanoi, one they called the Western Lake. My helmet and my oxygen mask had been blown off.
They told me that the Frenchman would visit me that evening. About noon, I was put in a rolling stretcher and taken to a treatment room where they tried to put a cast on my right arm. They had great difficulty putting the bones together, because my arm was broken in three places and there were two floating bones. I watched the guy try to manipulate it for about an hour and a half trying to get all the bones lined up. This was without benefit of Novocain. It was an extremely painful experience, and I passed out a number of times. He finally just gave up and slapped a chest cast on me. This experience was very fatiguing, and was the reason why later, when some TV film was taken, it looked to many people as if I had been drugged.
After about two weeks, I was given an operation on my leg which was filmed. They never did anything for my broken left arm. It healed by itself. They said I needed two operations on my leg, but because I had a "bad attitude" they wouldn't give me another one. What kind of job they did on my leg, I do not know. Now that I'm back, an orthopedic surgeon is going to cut in and see. He has already told me that they made the incision wrong and cut all the ligaments on one side.
When I said that, the guards, who were all in the room—about 10 of them—really laid into me. They bounced me from pillar to post, kicking and laughing and scratching. After a few hours of that, ropes were put on me and I sat that night bound with ropes. Then I was taken to a small room. For punishment they would almost always take you to another room where you didn't have a mosquito net or a bed or any clothes. For the next four days, I was beaten every two to three hours by different guards. My left arm was broken again and my ribs were cracked.
