Just finished reading a book by Mark Baker about US veterans in Vietnam. Quite ghastly in some places and obviously a few pyschopaths in the army. But this extract shows how ordinary men can descend into animals. Finally, dawn came. The battle broke off. There were literally hundreds and hundreds of Vietnamese fleeing the area, any way they could. Panic. ... I don't know if they ran out of ammunition or what, but we were taking very little fire at that point and we were just killing everybody. It turned into a turkey shoot. They were defenceless. There were three or four light fire teams working the area. Hundreds of people were being mowed down. ... I was in there with the best of them. Blowing people off the boats, out of the paddies, down from the trees. Blood lust. I can't think of a better way to describe it. Caught up in the moment. ... It was a slaughter. No better than lining people up on the edge of a ditch and shooting them in the back of the head. I was doing it enthusiastically. You begin at that point to understand how genocide takes pace. I consider myself a decent man, but I did mow those people down from my helicopter. A lot of people we were killing in the morning were the same people who were trying to kill us the night before. I tried to compensate in my head that most of the people we were wasting were the enemy. But I could appreciate in a black way that you can take anybody given the right circumstances and turn him into a wholesale killer. That's what I was. I did it. Bizarre. That's what it was. It was very bizarre.
