The U.S. Army accuses Capt. Ernest Medina and four other soldiers of committing crimes at My Lai (also known as Songmy) in March 1968. The charges ranged from premeditated murder to rape and the “maiming” of a suspect under interrogation. Medina was the company commander of Lt. William Calley and other soldiers charged with murder and numerous crimes at My Lai 4 in Song My village.

The My Lai massacre became the most publicized war atrocity committed by U.S. troops in Vietnam. Allegedly, a platoon had slaughtered between 200 and 500 unarmed villagers at My Lai 4, a cluster of hamlets in the coastal lowlands of I Corps Tactical Zone. This was a heavily mined region where Viet Cong guerrillas were firmly entrenched and numerous members of the participating platoon had been killed or maimed during the preceding month.

The company had been conducting a search-and-destroy mission. In search of the 48th Viet Cong (VC) Local Force Battalion, the unit entered My Lai but found only women, children, and old men. Frustrated by unanswered losses due to snipers and mines, the soldiers took out their anger on the villagers. During the attack, several old men were bayoneted, some women and children praying outside the local temple were shot in the back of the head, and at least one girl was raped before being killed. Many villagers were systematically rounded up and led to a nearby ditch where they were executed.

Reportedly, the killing was only stopped when Warrant Officer Hugh Thompson, an aero-scout helicopter pilot, landed his helicopter between the Americans and the fleeing South Vietnamese, confronting the soldiers and blocking them from further action against the villagers. The incident was subsequently covered up, but eventually came to light a year later. An Army board of inquiry headed by Lt. Gen. William Peers investigated the massacre and produced a list of 30 people who knew of the atrocity. Only 14, including Calley and Medina, were eventually charged with crimes.

All eventually had their charges dismissed or were acquitted by courts-martial except Calley, who was found guilty of murdering 22 civilians. He was sentenced to life imprisonment, but his sentence was reduced to 20 years by the Court of Military Appeals and further reduced later to 10 years by the Secretary of the Army. Proclaimed by much of the public as a “scapegoat,” Calley was paroled in 1974 after having served about three years.
