Operation Carlota: Cuba's 1975 Military Intervention in Angola

When Portugal’s colonial empire in Africa collapsed following the 1974 Carnation Revolution in Lisbon, Angola was left to three rival independence movements racing to control the country ahead of its scheduled November 11, 1975 independence date: the Soviet- and Cuban-aligned Popular Movement for the Liberation of Angola (MPLA), and the FNLA and UNITA, which drew backing from the United States, Zaire, and apartheid South Africa. In October 1975, South African forces crossed into Angola from Namibia in a covert operation codenamed Operation Savannah, advancing rapidly toward Luanda in support of the FNLA and UNITA and threatening to determine the outcome before independence was even declared.

Fidel Castro responded by ordering Cuban combat troops into Angola in an intervention codenamed Operation Carlota, named for Carlota Lucumí, an enslaved Yoruba woman who led a 1843 slave uprising at the Triunvirato sugar plantation in Matanzas, Cuba, before being killed during its suppression. The first Cuban unit, roughly 100 soldiers from a battalion several hundred strong, flew into Luanda in early November 1975, just ahead of the independence declaration; Cuban forces poured in by air and sea over the following weeks, reaching an estimated 3,500 to 4,000 troops by the end of 1975. The intervention escalated dramatically through 1976, with Cuban troop strength in Angola peaking at around 36,000 that year as Havana committed to a sustained campaign rather than a short intervention, figures that grew again later in the conflict, with roughly 55,000 to 60,000 Cuban personnel stationed in Angola by 1988, and a cumulative total of several hundred thousand Cuban soldiers and support staff rotated through the country across the full 1975–1991 deployment.

Cuban and MPLA forces halted the South African advance short of Luanda and pushed Pretoria’s troops back toward the Namibian border by early 1976, securing the MPLA’s hold on the newly independent government. On the American side, the CIA had been covertly funding and arming the FNLA and UNITA since mid-1975 through a program later revealed in congressional hearings, but that support was cut off in December 1975 when the US Senate passed the Clark Amendment, banning further covert US assistance to anti-MPLA forces in Angola, a rare instance of Congress moving decisively to check a US covert intervention in Africa in real time. South Africa continued to back UNITA and periodically intervene militarily in Angola for years afterward, but the events of late 1975 set the pattern for what became a grinding, externally fueled civil war that would not fully end until 2002; Cuban forces themselves remained in Angola until 1991, when their withdrawal was tied to the broader Namibian independence settlement they had helped force through years of continued fighting against South Africa.
