Battle of Khe Sanh, January 21, 1968 - April 8, 1968
Fought between the United States Marine Corps and the People's Army of Vietnam. Khe Sanh was a United States Marines military base in South Vietnam, constructed near the border with Laos. It became the largest offensive operation by PAVN and US Marines in 1968. The defense of the base was codenamed Operation Scotland. U.S. commanders provoked the battle hoping the PAVN would attempt to repeat their famous victory at the Battle of Dien Bien Phu. The overwhelming power of US air support and vastly increased airlift capacity made this impossible. After heavy casualties, the PAVN claimed the battle to be a diversionary tactic and abandoned the campaign in the aftermath of the Tet Offensive.
Vietnam casualties are thought to be have been about 9000+.
