From the Portuguese Colonial War (1961–1975) to Angola's independence, and the subsequent civil war in Angola (1975-2002) Huíla was directly affected only during relatively short periods of time. Cassinga was abandoned by its European supervisors, and the mine fell into neglect during the ensuing Angolan Civil War. The following year it was occupied by the People's Liberation Army of Namibia (PLAN), military wing of the South West African People's Organization. PLAN subsequently adopted Cassinga as a staging point for insurgent raids on South-West Africa, about 250 kilometres to the south. Their bases soon became a sanctuary for local refugees during the Namibian War of Independence.
