1968: My Lai

During the course of March 16th, 1968, US troops in the village of My Lai, Vietnam, systematically massacred several hundred people, mostly women, children, babies, and the elderly. The reason the outside world even knows that this event occurred is due to the helicopter crew under the command of pilot Hugh Thompson, who happened upon the scene while there were still a few villagers left alive, and intervened to save their lives.
