 From 1975 to 1979, Rhodesian troops and forces repeatedly entered into Mozambique in order to carry out operations against supposed ZANLA (Zimbabwe African National Liberation Army) bases tolerated on Mozambican territory by the FRELIMO government and to destabilise the FRELIMO government directly.These included the bombing of the Beira Port in 1979 and the occupation of the town of Mapai in 1977.During one such raid, Rhodesian forces freed FRELIMO ex-official André Matsangaissa from a re-education camp.
