The Battle of Cuito Cuanavale was fought intermittently between 14 August 1987 and 23 March 1988, south and east of Cuito Cuanavale, Angola, by the People's Armed Forces for the Liberation of Angola (FAPLA) and Cuba against South Africa and the National Union for the Total Independence of Angola (UNITA) during the Angolan Civil War and South African Border War. The battle was the largest engagement of the Angolan conflict and the biggest conventional battle on the African continent since World War II. UNITA and its South African allies defeated a major FAPLA offensive towards Mavinga, preserving the former's control of southern Angola. They proceeded to launch a failed counteroffensive on FAPLA defensive positions around the Tumpo River east of Cuito Cuanavale.
