The Battle of Huế, was one of the bloodiest and longest battles of the Vietnam War. In February 1968, in the South Vietnamese city of Huế, 11 battalions of the Army of the Republic of Vietnam (ARVN), two U.S. Army battalions, and three understrength U.S. Marine Corps battalions, for a total of 16 battalions, defeated 10 battalions of the People's Army of Vietnam (PAVN or NVA) and the Viet Cong (VC). With the beginning of the North Vietnamese Tet Offensive on January 30, 1968, the Vietnamese lunar New Year, large conventional American forces had been committed to combat upon Vietnamese soil for almost three years. Passing through the city of Huế, Highway 1 was an important supply line for ARVN, US, and Allied Forces from the coastal city of Đà Nẵng to the Vietnamese Demilitarized Zone (DMZ). It also provided access to the Perfume River (Vietnamese: Sông Hương or Hương Giang) at the point where the river ran through Huế, dividing the city into northern and southern parts. Huế was also a base for United States Navy supply boats.
