Hamburger Hill was the scene of an intense and controversial battle during the Vietnam War. Known to military planners as Hill 937, the solitary peak is located in the dense jungles of the A Shau Valley of Vietnam, about a mile from the border with Laos.

The Vietnamese referred to the hill as Dong Ap Bia (or Ap Bia Mountain, “the mountain of the crouching beast”). Though the hill had no real tactical significance, taking the hill was part of Operation Apache Snow, a U.S. military sweep of the A Shau Valley. The purpose of the operation was to cut off North Vietnamese infiltration from Laos and enemy threats to the cities of Hue and Da Nang.
