My Lai in central Vietnam was
the largest of a number of
hamlets in central Vietnam, that
together with the lesser hamlets Son My (fig.), Co Luy, My Khe, and Tu Cung, made
up a village that during the Vietnam War was known to the U.S. Military as
Pinkville, after the reddish-pink colour used on U.S. military maps to
denote the more populated areas.
