Apparently taken moments before they were killed.
I’m not even going to try and summarise this one. Below is a little bit from an article about it:
The Mỹ Lai Massacre was the Vietnam War mass killing of between 347 and 504 unarmed civilians in South Vietnam on March 16, 1968. It was committed by U.S. Army soldiers from the Company C of the 1st Battalion, 20th Infantry Regiment, 11th Brigade of the 23rd (America) Infantry Division.
Women and children killed.
Victims included men, women, children, and infants. Some of the women were gang-raped and their bodies mutilated.
One soldier shot himself in the foot; another sets a building on fire.
Twenty-six soldiers were charged with criminal offences, but only Lieutenant William Calley Jr., a platoon leader in C Company, was convicted.
Found guilty of killing 22 villagers, he was originally given a life sentence, but served only three and a half years under house arrest.
