The Battle of A Shau (Vietnamese: trận A Sầu) was waged in early 1966 during the Vietnam War between the People's Army of Vietnam (PAVN) and the forces of the United States and South Vietnam. The battle began on 8 March and lasted until 10 March with the fall of the U.S. Army's Special Forces camp of the same name. The battle was a strategic victory for the PAVN in that they were able to take control of the A Shau Valley and use it as a base area for the rest of the war.
