My Lai Massacre, mass killing of as many as 500 unarmed villagers by U.S. soldiers in the hamlet of My Lai on March 16, 1968, during the Vietnam War.

Charlie Company

My Lai, a subdivision of Son My village, was located in the province of Quang Ngai, roughly 7 miles (11 km) northeast of Quang Ngai city. The area had been dubbed “Pinkville” by U.S. soldiers because of the reddish colour used to indicate the densely populated My Lai area on military maps. By the time Charlie Company of the 1st Battalion, 20th Infantry Regiment, 11th Infantry Brigade, arrived in Vietnam in December 1967. “Pinkville” had earned a reputation as a heavily mined hotbed of Viet Cong activity. In January 1968 Charlie was one of three companies tasked with the destruction of the 48th Battalion, an especially effective Viet Cong unit operating in Quang Ngai province. Throughout February and early March, Charlie Company suffered dozens of casualties due to mines and booby traps, but it failed to engage the 48th Batallion. After the debacle of the broad Tet Offensive, the Viet Cong had returned to guerrilla tactics and tended to avoid direct encounters with U.S. forces.

Intelligence suggested that the 48th Batallion had taken refuge in the My Lai area (though in reality, that unit was in the western Quang Ngai highlands, more than 40 miles [65 km] away). In a briefing on March 15, Charlie Company’s commander, Capt. Ernest Medina, told his men that they would finally be given the opportunity to fight the enemy that had eluded them for over a month. Believing that civilians had already left the area for Quang Ngai city, he directed that anyone found in My Lai should be treated as a Viet Cong fighter or sympathizer. Under these rules of engagement, soldiers were free to fire at anyone or anything. Moreover, the troops of Charlie Company were ordered to destroy crops and buildings and to kill livestock.

Massacre at My Lai

Shortly before 7:30 am on March 16, 1968, Son My village was shelled by U.S. artillery. The preparatory barrage was intended to clear a landing area for Charlie Company’s helicopters, but its actual effect was to force those civilians who had begun leaving the area back to My Lai in search of cover. Minutes later, Charlie Company’s 1st Platoon, led by Lieut. William Calley, was inserted a short distance to the west of a sub-hamlet known locally as Xom Lang but marked as My Lai (4) on U.S. military maps.

By 7:50 am the remainder of Charlie Company had landed, and Calley led 1st Platoon east through My Lai. Although they encountered no resistance, the soldiers nonetheless killed indiscriminately. Over the next hour, groups of women, children, and elderly men were rounded up and shot at close range. U.S. soldiers also committed numerous rapes. Charlie Company’s 2nd Platoon moved north from the landing zone, killing dozens, while 3rd Platoon followed behind, destroying the hamlet’s remaining buildings and shooting survivors. At 9:00 am Calley ordered the execution of as many as 150 Vietnamese civilians who had been herded into an irrigation ditch.

Sgt. Ron Haeberle, a U.S. Army photographer attached to Charlie Company, documented the events of the day. He used a black-and-white camera for official Army records but shot in colour on his personal camera. Many of the black-and-white images depicted soldiers questioning prisoners, searching possessions, and burning huts; although the destruction of property violated U.S. military command directives, such actions were typical of a search-and-destroy mission and did not provide direct evidence of war crimes. Haeberle’s personal colour photographs, which he did not turn over to the Army, were later published in the Cleveland Plain Dealer and Life magazine. One graphically depicted a trail littered with the bodies of dead women, children, and infants, and another captured a group of terrified women and children moments before they were shot. These photographs served to galvanize the anti-Vietnam War movement and would become some of the most recognizable images of the war.

As the massacre was taking place, Warrant Officer Hugh Thompson was flying a scout helicopter at low altitude above My Lai. Observing wounded civilians, he marked their locations with smoke grenades and radioed for troops on the ground to proceed to those positions to administer medical aid. After refueling, Thompson returned to My Lai only to see that the wounded civilians subsequently had been killed. Spotting a squad of U.S. soldiers converging on more than a dozen women and children, Thompson landed his helicopter between the two groups. Thompson’s door gunner, Lawrence Colburn, and his crew chief, Glenn Andreotta, manned their weapons as Thompson hailed other helicopters to join him in ferrying the civilians to safety. In 1998 Thompson, Colburn, and Andreotta (posthumously) were awarded the Soldier’s Medal for acts of extraordinary bravery not involving contact with the enemy.

By 11:00 am as many as 500 Vietnamese civilians had been killed. Medina ordered Charlie Company to break for lunch and informed his superiors that scores of Viet Cong had been killed in the operation. The sole U.S. casualty had occurred when a soldier shot himself in the foot while trying to clear a jammed weapon.
