Another key turning point during the Vietnam War was the My Lai massacre. The mass killing of Vietnamese civilians by U.S. soldiers took place on March 16, 1968, but did not become public until late 1969, when Seymour Hersh, journalist, reported the story. At the same time, the military tried Lieutenant William Calley with murder. You will study the varying responses to the killing of over 300 unarmed women, men, and children. In particular, you will view the massacre at My Lai from five different perspectives: (1) Army Photographer William Haeberle and LIFE magazine journalists, (2) Lieutenant William Calley; (3) Lewis B. Puller Jr, a Vietnam veteran who wrote about the massacre in his autobiography; (4) Nguyen Hieu, an eye-witness, at My Lai; and (5) the Peers Commission report, the Army’s official investigation of the My Lai massacre and cover up.
