By 1971, charges were pending only against Lt. Calley, Capt. Ernest Medina, and Capt. Eugene Kotouc. On March 29, 1971, a Fort Benning court-martial jury found Calley guilty of the premeditated murder of at least 22 South Vietnamese civilians and sentenced him to life in prison. Kotouc was cleared by a court-martial on April 29, and Medina was acquitted on September 22.
On May 19, the Army disciplined two generals for failing to conduct an adequate investigation of My Lai, demoting Maj. Gen. Samuel W. Koster from two-star to one-star rank. At the same time, both Koster and Brig. Gen. George W. Young Jr., his assistant divisional commander at the time of the massacre, were stripped of their Distinguished Service Medals, and letters of censure were placed in their personnel files. The trials ended on December 17, when Col. Oren K. Henderson was acquitted of cover-up charges. He was the highest-ranking officer to be tried.
Of those originally charged, only Calley was convicted. Many believed that Calley was a scapegoat, and the widespread public outcry against his life sentence moved President Nixon to intervene on April 3, 1971. He had Calley removed from the Fort Benning stockade and ordered him confined to quarters pending review of his case. On August 20, Calley’s life term was reduced to 20 years. In November 1974, a Federal Court judge ruled that Calley was convicted unjustly, citing “prejudicial publicity.” Although the Army disputed this ruling, Calley was paroled for good behavior after serving 40 months, 35 of which were spent in his own home.
