One of the Vietnam War's largest military campaigns, the Tet Offensive was conceived to accomplish nothing less than the elimination of the U.S. military presence in Vietnam and the overthrow of the South Vietnamese government.
The North Vietnamese Tet Offensive of early 1968 was designed to spark a general uprising in South Vietnamese cities and to cause the collapse of the South Vietnamese army and government.
Located only 30 kilometers south of the Demilitarized Zone, Quang Tri was arguably South Vietnam's most vulnerable provincial capital. As Tet drew near, the question was not whether Quang Tri would be attacked, but when.
The titanic struggle for Hue occurred at the height of the Tet Offensive. One of the Vietnam War's longest and bloodiest battles, America has not experienced urban combat since then, exceeding its scale of the fighting.
In May 1968, the major port city of Da Nang was threatened by mounting North Vietnamese and Viet Cong deployments. An assault on Da Nang was prevented by U.S. Marine Corps operations to the southwest of that city.
