My Lai Massacre: The Vietnam War Atrocity That Shocked the World

The My Lai Massacre remains one of the most infamous atrocities of the Vietnam War, when U.S. soldiers killed hundreds of unarmed civilians in a South Vietnamese village.On March 16, 1968, in Quảng Ngãi Province, South Vietnam, soldiers of Charlie Company, 11th Infantry Brigade, Americal Division entered the village of My Lai expecting to confront Viet Cong fighters. Instead, they encountered unarmed civilians—women, children, and elderly men. What followed became one of the darkest chapters of the Vietnam War: the My Lai Massacre.Over the course of several hours, U.S. troops systematically killed hundreds of villagers. Civilians were rounded up, shot at close range, executed in irrigation ditches, and their homes burned. Lieutenant William Calley ordered his men to open fire on groups of civilians, personally participating in the killings. Captain Ernest Medina, the company commander, was also present during the operation. By the end of the massacre, as many as 504 Vietnamese civilians were dead, including dozens of young children. The atrocity might have remained hidden if not for Warrant Officer Hugh Thompson, a U.S. Army helicopter pilot who intervened to stop further killings and helped evacuate survivors. Later, soldier Ronald Ridenhour exposed the events, and journalist Seymour Hersh brought the story to the American public. The Peers Commission confirmed war crimes had occurred, yet only William Calley was convicted—and he ultimately served just three and a half years under house arrest. The My Lai Massacre became a turning point in public opinion, deepening opposition to the Vietnam War and raising profound questions about war crimes, military accountability, and the moral cost of modern warfare. It remains one of the most infamous atrocities of the Vietnam War.This episode is part of the series The Vietnam War.Watch the full documentary and explore hundreds of historical films at:WorldHistory.tv
