The My Lai massacre was one of the most horrific incidents of violence committed against unarmed civilians during the Vietnam War. A company of American soldiers brutally killed most of the people—women, children and old men—in the village of My Lai on March 16, 1968. More than 500 people were slaughtered in the My Lai massacre, including young girls and women who were raped and mutilated before being killed. U.S. Army officers covered up the carnage for a year before it was reported in the American press, sparking a firestorm of international outrage. The brutality of the My Lai killings and the official cover-up fueled anti-war sentiment and further divided the United States over the Vietnam War.
