All of the above six photos are from the Battle of Hue. "The Battle for Hue [was fought] for 26 days as US and South Vietnamese forces tr[ied] to recapture the site seized by the Communists during the Tet Offensive. Previously, a religious retreat in the middle of a war zone, Hue was nearly leveled in a battle that left nearly all of its population homeless. Following the US and ARVN victory, mass graves containing the bodies of thousands of people who had been executed during the Communist occupation [were] discovered" (PBS, The American Experience).
