Seymour Hersh, an independent investigative journalist, broke the story of the My Lai Massacre in a series of articles published in 1969. His investigation unveiled the horrific actions taken by U.S. Army soldiers during a search-and-destroy mission in the My Lai hamlets of Quang Ngai Province, Vietnam, on March 16, 1968. In this incident, hundreds of unarmed South Vietnamese civilians, including women, children, and the elderly, were systematically killed over several hours. Hersh's reporting was based on interviews with soldiers, as well as testimony from a helicopter pilot who had witnessed the massacre and attempted to intervene. The story gained momentum and was later corroborated by further reports and investigations.Hersh's revelations shone a harsh light on the conduct of U.S. forces in Vietnam and raised questions about military oversight and accountability. The My Lai Massacre was downplayed for many months, but once Hersh's story broke, it resulted in a massive public outcry. This incident further fueled anti-war sentiment within the United States, as many citizens were horrified to learn about the extent of violence against civilians. The international community also reacted strongly, criticizing U.S. military tactics and the Vietnam War itself.The fallout from the My Lai Massacre had significant consequences for both the U.S. military and the American public's perception of the Vietnam War. As the truth about the incident emerged, numerous soldiers were implicated, leading to trials and convictions, albeit limited numbers. The event indelibly marked a turning point in the Vietnam War narrative, with public trust in the U.S. government and military being severely shaken.
