Battle of Khe Sanh - Vietnam War - HISTORY.com

The Battle of Khe Sanh began on January 21, 1968, when forces from the People’s Army of North Vietnam (PAVN) carried out a massive artillery bombardment on the U.S. Marine garrison at Khe Sanh, located in northwest South Vietnam near the Laotian border. For the next 77 days, U.S. Marines and their South Vietnamese allies fought off an intense siege of the garrison, in one of the longest and bloodiest battles of the Vietnam War. Meanwhile, with U.S. and South Vietnamese attention focused on Khe Sanh, North Vietnamese and Viet Cong forces launched the Tet Offensive, a series of coordinated surprise attacks on cities and towns throughout South Vietnam.
