The CIA correctly predicted that Cuba and the Soviet Union would continue to support FAPLA at whatever level was necessary to prevail, while South Africa was inclined to withdraw its forces rather than risk incurring heavy casualties. The SADF had suffered between 28 and 35 killed in action. An additional 100 were wounded. Seven South Africans were captured and displayed at Angolan press briefings as living proof of the SADF's involvement. Cuban casualties were known to be much higher; several hundred were killed in engagements with the SADF or UNITA. Twenty Cubans were taken prisoner: 17 by UNITA, and 3 by the South Africans. South Africa's National Party suffered some domestic fallout as a result of Savannah, as Prime Minister Vorster had concealed the operation from the public for fear of alarming the families of national servicemen deployed on Angolan soil. The South African public was shocked to learn of the details, and attempts by the government to cover up the debacle were slated in the local press.
