High Quality Content by WIKIPEDIA articles! Hugh Clowers Thompson, Jr., DFC, BSM, PH, AM (April 15, 1943 – January 6, 2006) was a United States Army helicopter pilot during the Vietnam War. He is most well known for his role in stopping the My Lai Massacre, in which a group of US Army soldiers tortured and killed several hundred unarmed Vietnamese civilians, mutilating their bodies after they had been murdered. Although initially ill-treated in some quarters for their intervention, Thompson and his crew, Glenn Andreotta and Lawrence Colburn, were recognized and decorated many years later for their heroism at My Lai. Andreotta had died in combat three weeks after the massacre, and so was honored posthumously.
