area, only some advance posts and temporary bases used by RENAMO as launching pads for food raids into Zimbabwe. It was also revealed for the first time that the main RENAMO bases were at Messinse, Chito, Nyazonia, Buetoni, Gorongosa Central Base and Casa Banana. Operation Grape Fruit The report for Operation Lemon was taken seriously by the commanders of the ZDF, and in July 1985 preparations for major offensive operations were started. Rehearsals for a Fireforce operation were carried out at Inkomo Barracks near Harare. Three infantry brigades were mobilised together with the Parachute Group, One Commando Battalion and the AFZ. Men and equipment were moved to Chimoio in Mozambique, with a Forward Replenishment Point (FRP) being established at Grand Reef near Mutare. Intelligence sources had indicated that RENAMO's main regional base in Manica province was at Muxamba and that Casa Banana was the national stronghold of RENAMO. Both bases had to be attacked and Muxamba was targeted first, being only 70 kilometres south of Chimoio. The most important consideration however, was the hope that activities around Muxamba might divert RENAMO's attention from monitoring too closely the movement of the three heavily armed Zimbabwean infantry battalions marching from Chimoio towards the Gorongosa Mountains.

The attack on Muxamba was launched on 20 August 1985 by elements of 3 Brigade, supported by the Parachute Group and the AFZ. The operation went on for four days with minor problems for the ZDF. One helicopter was riddled with small arms fire but managed to return to Chimoio. Raid on Cassa Banana Intelligence sources had indicated that Cassa Banana, RENAMO's national headquarters had a strength of 400 elements. However, the organisation maintained a string of other smaller bases along the Gorongosa Mountains, which were considered as part of the main base. This raised the total estimated strength in the area to 1,000 elements. During the night of 27 August 1985, three Zimbabwe infantry battalions were established in their Form Up Points (FUP) with the help of the SAS and Commando elements. At Chimoio a Fireforce was being given final briefing, and five AFZ planes were given orders for a first light take-off for Gorongosa on the morning of 28 August. Although the RENAMO elements captured at Katiyo had given a grid reference for Cassa Banana, further intelligence had cast some
