"The fact is that Calley had just been following orders. There had been increasing pressure from commanders for higher kill counts, and his exact orders when entering My Lai were to search and destroy. No American volunteered or was drafted for the purpose of killing civilians. In fact, when Calley and his men first arrived, they tried very hard to win over the South Vietnamese. As time went on, they noticed the locals were purposefully not helping them fight the Vietcong. Soldiers faced violence from men, women, and children of all ages during combat. The Vietcong were also heinously murdering captured soldiers. On one occasion, Calley recalled a soldier who had been captured, skinned alive, and bathed in a salt solution. The next day, they found the man’s skin ripped from his body and strung on a pole, with his penis having also been cut off."
