The My Lai Massacre (Vietnamese: thảm sát Mỹ Lai [tʰɐ̃ːm ʂɐ̌ːt mǐˀ lɐːj], [mǐˀlɐːj] ( listen); /ˌmiːˈlaɪ/, /ˌmiːˈleɪ/, or /ˌmaɪˈlaɪ/) While 26 U.S. soldiers were initially charged with criminal offenses for their actions at Mỹ Lai, only Second Lieutenant William Calley, a platoon leader in Charlie Company, was convicted. Found guilty of killing 22 villagers, he was originally given a life sentence, but only served three and a half years under house arrest.
