Gorongosa Offensive

The Gorongosa Offensive was a military operation by the People's Republic of Mozambique beginning in January 1980 aimed at destroying the RENAMO bases around the Gorongosa area which were increasingly threatening roads, towns, communication lines, FPLM troops and more. The Gorongosa Offensive was the first major military offensive launched by the FPLM during the war.

Prelude
Beginning in August 1979 RENAMO began their activity in Gorongosa traveling from their base in Odzi, Rhodesia. They set up a base on the main Gorongosa Mountain and established several other smaller positions near the mountain. In September 1979 RENAMO expanded even further from their main base in Gorongosa capturing Macossa to the north and M’sucossa to the south as well as running reconnaissance missions in the Gorongosa plateau. During October FPLM recaptured Macossa and in mid-October RENAMO launched an attack on Morombodze and from there launched an attack on the town of Gorongosa south of the mountain. The attack led to the defeat of RENAMO with their leader André Matsangaissa being killed during the battle. RENAMO withdrew to their positions prior to the attack. In November RENAMO expanded eastward to Inhaminga laying siege to the town for over a week and also briefly occupied the towns of Maringué and Mazamba. In December FPLM deployed troops near Mount Gorongosa to the west which RENAMO overran on 30 December.

Offensive
The offensive was planned by the Soviets who had advisors present in Beira during the operation. Additionally, prior to the attack Frelimo offered amnesty to any RENAMO rebel who surrendered with their weapons. The offensive began in January with the destruction of the RENAMO base near Inhaminga which was captured through an artillery shelling followed by a two-pronged assault that quickly captured the camp. The next day Frelimo forces began advancing from the Dondo-Inhaminga road westwards towards the main base on Gorongosa Mountain however their forces became bogged down in wet and muddy terrain traveling through the Gorongosa National Park which took the soldiers two days to reach their next positions near the east side of the mountain. South of the town of Gorongosa another brigade was moving northwards on the Inchope road toward the town where eventually all the forces would meet to launch an assault on the main base on the Gorongosa Mountain. RENAMO instead of facing the large number of Frelimo forces decided to retreat from their bases on the Gorongosa Mountain and surrounding areas and the offensive came to a close in February with Frelimo drawing down their presence in the region on 5 March.

Aftermath
Following the offensive RENAMO chose to abandon all of their operations north of the Beira-Umtali corridor and withdraw to their Sitatonga 2 base in southern Manica Province which the FPLM would capture a couple of months later during Operation Leopard. However this plan was temporary with RENAMO stashing weapons caches in the Gorongosa area in preparation for their return.
