The Tet Offensive (officially <em>The General Offensive and Uprising of Tet Mau Than 1968</em>) was one of the largest military campaigns of the Vietnam War, launched on January 30, 1968 by forces of the Viet Cong and North Vietnamese People's Army of the Republic of Vietnam against the forces of the South Vietnamese Army of the Republic of Vietnam, the United States Armed Forces, and their allies.
