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 action 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. Attacks were repeatedly repelled by North Vietnamese Army (NVA) defenses, weather, friendly fire, and accidents. Nevertheless the Airborne troops took the hill through direct assault, causing extensive casualties to the NVA forces.
