The Operation Zeta was a military action between Portuguese and FRELIMO forces during the Portuguese Overseas War. It took place from June 6 to 11, 1969, in the Malambuage swamp, a wetland region on the south bank of the Ruvuma River, in the current province of Cabo Delgado. ^[1]

More than two hundred paratroopers jumped over the Malambuage swamp, surprised and stormed FRELIMO strongholds; They killed several dozen guerrillas during the fiercest fighting, seized large quantities of war material and surrounded the entire enemy cantonment area. For three days, the paratroopers consolidated their dominant positions, covered the ground between the Ruvuma river and the base of Limpopo, in Balade, south of the swamp, searched and lifted FRELIMO mines/traps and finally, made connections with the FRELIMO combat groups that surrounded the buffer-shaped area to the south, east and west of the Ruvuma river. In those days of intense combat, a company of Commandos took over the logistical camp from the guerrillas, south of the swamp. The two Army Companies, the C. Cav. 2376 of Nangade broke into the woods near the Lidede lake and the Nange river valley and assaulted a guerrilla hospital, collecting various war material, documents and capturing enemy elements. The other Army Company, C. Cav. 2375 from Mocimboa do Rovuma, hit the land west of the swamp and helped the paratroopers to collect the jumping material.

During the entire operation, air support was important, with a Dornier Do 27 in operational command, a helicopter armed with heavy machine guns, eight T6 aircraft to attack enemy groups trying to escape the siege, two PV2 bomber aircraft, four Nordatlas and three Dakotas at the paratroopers' launch. The bombing of fugitive guerilla groups helped to weaken their combative momentum and cut off their lines of escape.

Due to the meticulous collection of information, carefully tested, and the consequent secrecy in very short-term planning, Operation Zeta was one of the most important military missions carried out in Mozambique. The results attest to the success of Portuguese troops, whose coordination exceeded the best prospects, given the impossibility of accessing an area controlled by the enemy and the distances from any support point without being dismounted.

The Commander of the 32nd Parachute Hunter Battalion, based in Nacala, was in charge of coordinating all troops in action, especially air support, marking precursors, means of collecting parachutes, logistics for the auto columns that collected the personnel and the seized material. The paratroopers involved in the actions that culminated in this operation belonged to BCP32 and BCP31. Its high mobility allowed it to inflict a resounding defeat on the guerrillas, dismantling their infiltration lines from bases in Tanzania, namely the logistical command in Nachingwea and the personnel coming from the training center in Mtwara, using the road from Mahuta to Newala , north of the Ruvuma river. The number of hidden paths, trails and hiding places spread across an area larger than twenty football fields was indeed impressive, most of it towards the river crossing point, towards the road that connects to the interior of Tanzania.

Seized material

The joint action of around 680 determined men, just over a dozen planes and four dozen vehicles arrived to defeat more than two hundred guerrillas, destroying their shelters, dismantling logistical support camps, burning food and barns and driving the livestock into the bush. However, some more “skilled” paratroopers manage to “elude” the sight of the leaders (by keeping them inside their camouflage and in their backpacks) and, in the last day, present a few dozen chickens for a barbecue; is that, after this setback suffered by the enemy, there was nothing more to fear.

In addition to the precious documentation on FRELIMO's organization, more than 7,600 kg of valuable war material, bicycles and other means of transport across the Ruvuma river were seized.
