My Lai massacre
Main article: My Lai massacre
On March 16, 1968, Calley led around 100 soldiers of Charlie company into the village of My Lai. Although they faced no resistance, they entered the village shooting. They murdered hundreds of civilians consisting mostly of South Vietnamese elderly men, women, children, and infants using automatic weapons, grenades and bayonets. Infants and children were killed with bayonets, and females were ***** and shot.[10]

The official American estimate of those murdered was 347, but a Vietnamese memorial at the site lists 504 names, with ages ranging from 1 to 82.[10] In the My Lai museum in Vietnam, a marble plaque lists the names and ages of the victims. The count of the dead is a total of 504 people from 247 families. Of these, 24 families lost everyone – three generations, no survivors. Included in the 504 were 60 elderly men, and 282 women (17 of whom were pregnant). A total of 173 children were killed; 53 were infants.[11]
