PLAN was attempting to rebuild its forward operating bases after the loss of Chetequera. The insurgents had also been incensed by the Cassinga raid and publicly threatened retribution. "Strike a hard blow which Pretoria will not forget in a long time," deputy PLAN commander Solomon Huwala stated in a written directive to his staff. "We have been concentrating on attacking military targets and their forces, but they have decided to kill women and children. Cassinga must be revenged." It was from this communique that the name of the next major PLAN offensive was derived: Operation Revenge. After some deliberation, Huwala chose Katima Mulilo as his target and dispatched several PLAN reconnaissance teams to obtain data on firing positions and potential artillery observation posts. On 23 August 1978, PLAN bombarded Katima Mulilo with mortars and rocket fire, killing 10 SADF personnel. The next day, General Viljoen, General Geldenhuys and the Administrator-General of South West Africa flew out to Katima Mulilo to inspect the damage. All three narrowly escaped death when their SA.321 Super Frelon helicopter took ground fire from PLAN anti-aircraft positions at Sesheke. The SADF responded by bombarding Sesheke with its own artillery and making a sweep for PLAN insurgents up to a hundred kilometers north of the Cutline.
