The Battle of Hamburger Hill was a battle of the Vietnam War that was fought by the United States and South Vietnam against North Vietnamese forces from May 10–20, 1969. Although the heavily fortified Hill 937 was of little strategic value, U.S. command ordered its capture by a frontal assault, only to abandon it soon thereafter. The debacle caused an outrage both in the American military and public. The battle was primarily an infantry engagement, with the U.S. Airborne troops moving up the highly sloped hill against well entrenched troops.
