1975 spring offensive
The 1975 spring offensive (), officially known as the general offensive and uprising of spring 1975 () was the final North Vietnamese campaign in the Vietnam War that led to the capitulation of South Vietnam. After the initial success capturing Phước Long Province, the North Vietnamese leadership increased the scope of the People's Army of Vietnam's (PAVN) offensive and captured and held the key Central Highlands city of Buôn Ma Thuột between 10 and 18 March. These operations were intended to be preparatory to launching a general offensive in 1976.
