Also known as the Battle of the Lomba River, this battle took place near the town of Cuito Cuanavale in southern Angola. To the
South African Defence Force, it took the form of four phases, which ran consecutively as a single overall battle. These were: •
Operation Moduler – The aim of which was to halt and reverse the FAPLA advance on the UNITA strongholds of Mavinga and Jamba. •
Operation Hooper – The aim of which was to inflict maximum casualties on the retreating FAPLA forces after they had been halted, to ensure there were no further attempts to resume the advance. •
Operation Packer – The aim of which was to force the FAPLA forces to retreat to the west of the
Cuito River, and to provide UNITA with a sustainable self-defence. •
Operation Displace – The aim of which was to maintain a deterrence to any resumed advance against UNITA, while the bulk of the troops and equipment were withdrawn.
Operation Moduler On 4 August 1987, the SADF launched Operation Moduler, which was to stop the Angolan advance on Mavinga to prevent a rout of UNITA. The SADF 61 Mechanized Battalion crossed into Angola from their base at the border town of
Rundu. It was subsequently reinforced inside Angola by
32 Battalion, a special forces unit made up primarily of dissident Angolans led by SADF officers, as well as
101 Battalion of the auxiliary
South West African Territorial Force (SWATF). In August FAPLA's 16th, 21st (both light infantry), 47th (armoured) and 59th (mechanized) brigades, about 6,000 men and 80 tanks plus artillery and support vehicles, departed from Cuito Cuanavale to cross the Lomba River. They received air support from the airbase at
Menongue, including
MiG 23s deployed in ground attacks. Facing them were the UNITA forces composed of the 3rd Regular, 5th Regular, 13th Semi-Regular and 275th Special Forces Battalions, supported by about 1,000 SADF troops with armoured vehicles and artillery. On 28 August FAPLA reached the northern banks of the Lomba River en route to Mavinga, where they were engaged by the SADF. In a series of bitter fights between 9 September and 7 October, SADF and UNITA achieved their primary objective of preventing the FAPLA from crossing the river. The Soviets withdrew their advisors and left the FAPLA without senior leadership, and FAPLA forces crumbled and ran. FAPLA suffered heavy losses, with all four brigades losing about 60–70% of their strength. Throughout the battle, FAPLA had lost 1,059 dead and 2,118 wounded, along with 61 tanks, 83 armoured vehicles and 20 rocket launchers. UNITA lost 155 killed and 622 wounded, the SADF lost 19 killed and 41 wounded and 5 armoured vehicles. The SADF also captured a highly sophisticated
SA-8 anti-aircraft missile system – the first time the weapon had fallen into western hands. The Angolan army headed into a retreat over 190 km back to Cuito Cuanavale, which it desperately held on to.
Chester Crocker, who was the
U.S. Assistant Secretary of State for African Affairs during the
Reagan Administration, said that: "In some of the bloodiest battles of the entire civil war, a combined force of some 8,000 UNITA fighters and 4,000 SADF troops not only destroyed one FAPLA brigade but badly damaged several others out of a total FAPLA force of some 18,000 engaged in the three-pronged offensive. Estimates of FAPLA losses ranged upward of 4,000 killed and wounded….Large quantities of Soviet equipment were destroyed or fell into UNITA and SADF hands when FAPLA broke into a disorganized retreat... The 1987 military campaign represented a stunning humiliation for the Soviet Union, its arms and its strategy. ... As of mid-November, the UNITA/SADF force had destroyed the Cuito Cuanavale airfield and pinned down thousands of FAPLA's best remaining units clinging onto the town's defensive perimeters." On 29 September, South African and UNITA forces, having gained the upper hand, launched a counter-attack. The objective was to inflict a crushing blow to the FAPLA, so that they would not consider another offensive in the following year. During this phase the SADF units were supported by heavy artillery and air strikes. The airstrip at Cuito Cuanavale was extensively bombarded, causing the Cubans to withdraw their aircraft to Menongue and to abandon the Cuanavale airstrip. On 9 November the SADF attacked the FAPLA 16th brigade. Air strikes and artillery were used, and tanks went into battle alongside the armoured vehicles. UNITA infantry also participated. The 16th brigade was mauled, and withdrew in disarray back across the river. The battle ended after half a day, when the SADF vehicles ran low on ammunition and broke off the attack. FAPLA had 10 tanks destroyed and 3 captured, various artillery pieces destroyed or captured, and 75 men killed. The SADF had 7 killed and 9 wounded, plus one armoured vehicle destroyed, one damaged and a tank damaged. The second attack, on 11 November, again targeted the 16th brigade. Again 16th brigade escaped annihilation by crossing the river, but this time they lost 14 tanks and 394 men. The SADF had 5 men killed and 19 more wounded, with 2 armoured vehicles destroyed and one tank damaged. The recovery, under fire, of a crippled tank and the subsequent re-entry of a minefield where the tank was extracted from to rescue a wounded soldier, earned Captain Petrus van Zyl and Lieutenant De Villers Vosloo of
32 Battalion both
Honoris Crux decorations. The FAPLA 21st brigade withdrew rapidly across the river, and was pursued. On 17 November they were engaged again, and suffered 131 casualties, along with 9 tanks destroyed and about 300 other vehicles. The SADF suffered 6 casualties and 19 wounded, plus 4 armoured vehicles. A final attack on 25 November bogged down in heavy bush, and was eventually abandoned. Operation Moduler achieved the objective of halting the FAPLA advance against UNITA, and inflicted heavy losses on FAPLA. In Luanda, Angolan President
José Eduardo dos Santos summoned General Gusev and the senior Cuban general officer, Gustavo Fleitas Ramirez, for an urgent conference to discuss the worsening military situation and the failure of Operation Saluting October. With no functioning armour or artillery remaining, the FAPLA units faced annihilation. On 15 November, the Angolan government requested direct military assistance from Cuba.–200 technicians, advisers, officers, and special forces. By the beginning of January, this had been increased to about 1,500 troops, including tank crews. and in the aftermath of Angolan hostilities a year later when Ochoa was arrested, tried and executed by firing squad after being found guilty of treason. General Cintras Frias was made commander at Cuito Cuanavale. The Cuban's initial priority was securing Cuito Cuanavale, but while reinforcements were arriving at the besieged garrison they made preparations for a second front to the west of Cuito Cuanavale in
Lubango where the SADF had been operating unhindered for 8 years. On 25 November, the
UN Security Council demanded the SADF's unconditional withdrawal from Angola by 10 December. The SADF units received fresh troops and equipment, but the units were reduced to about 2,000 men and 24 tanks for the rest of the operation. The new arrivals had to be acclimatised first. The SADF objective was defined as being to destroy the enemy east of the river or at least to drive them back across the river, inflicting maximum casualties but suffering minimum losses of their own. The river crossings were to be fortified and handed over to UNITA, and the SADF were to withdraw from Angola as soon as that was achieved. The order was that the town of Cuito Cuanavale would not be attacked unless it fell into SADF hands almost without a fight. The Cubans managed to construct a wooden footbridge in its place which they baptised
Patria o Muerte (fatherland or death). They partly buried disabled tanks so that their turrets could be used as fixed artillery pieces. 32 Battalion and elements of other units harried the road convoys for weeks, destroying several hundred tanks and other vehicles, and inflicting an unknown number of casualties. s in the counter-attack against SADF advance units on 14 February. On 13 January the SADF attacked the 21st brigade, starting with air strikes and artillery bombardments. Over two days the FAPLA unit was driven out of their positions, and lost 7 tanks with 5 more captured, various other vehicles destroyed and captured, and 150 men dead or captured. UNITA lost 4 dead and 18 wounded, and the SADF had one man wounded and one armoured vehicle damaged. However the SADF was again unable to exploit the momentum, due to a shortage of reserves and supplies. UNITA occupied the captured positions, and the SADF withdrew, but UNITA lost the positions later to a FAPLA counter-attack. A large Cuban and FAPLA column was on the way from Menongue for the relief of Cuito Cuanavale, but progress in the rainy season was slow due to the need to clear the UNITA minefields and guard against possible ambushes. They did not reach Cuito Cuanavale in time to take part in the first engagement. FAPLA withdrew to the Tumpo (river) triangle, a smaller area east of the river and across from Cuito Cuanavale. The land west of the Cuito river was ideal defensive territory as it was higher than the East bank, and the direction of attack forced the SADF to attack into the setting sun towards the afternoon. The high ground enabled FAPLA to deploy artillery over the horizon, out of sight of the SADF forward observers. They also laid extensive minefields in all of the routes that led to Cuito Cuanavale. In an assault on 19 February a FAPLA position was disrupted, and it resulted in the FAPLA 59th brigade being withdrawn across the river. However the SADF had run into a minefield south of the FAPLA positions, which destroyed 2
Ratels. The explosions of the mines drew immediate artillery fire which forced the SADF to withdraw. The SADF launched another attack on 25 February, when an artillery barrage forced the FAPLA 25th brigade to withdraw to the bridgehead on the Tumpo river. The retreat was orderly, covered by Cuban aircraft. South African tanks soon advanced, but when one of them detonated a mine, it immediately alerted the Cubans and Angolans to the direction of their advance. The SADF was soon harassed by continuous artillery fire and Cuban airstrikes, which destroyed 2
Ratels and 3 vehicles. With casualties beginning to mount, the assault was soon called off. Although the FAPLA suffered heavy casualties, 172 FAPLA and 10 Cubans killed. The withdrawal to the Tumpo bridgehead was successful and the troops had simultaneously repelled a South African offensive, their first success after nearly 5 months of continuous disaster. Two days later, Castro sent a congratulatory message to the men of the 25th and 59th brigades.
Operation Packer On the night of 22 March, around 21h00, the SADF units began to line up and prepare for an offensive to drive the Cubans and Angolans from the Tumpo Triangle, which would begin the next morning. Several damaged South African tanks were abandoned in the minefield, and were subsequently captured by the Cubans and Angolans. This provided a huge propaganda victory for Castro. The SADF equipment, men and supplies were exhausted, and the SADF command determined that destroying the small FAPLA force remaining on the eastern bank of the river was not worth further casualties. The objective of protecting UNITA was deemed to have been achieved, and Operation Packer ended. The Tumpo Triangle campaign exposed several flaws in the planning of the South African defence chiefs and general staff. They had estimated quite accurately that their forces would be able to inflict a crushing defeat on FAPLA in the flood plains and open terrain south of Cuito Cuanavale. But they had not anticipated so many Angolan units would survive and establish strong defensive lines in the Tumpo Triangle, or that the addition of Cuban troops there would stiffen the resistance considerably. It was soon realized that the SADF and UNITA would not be able to push the FAPLA/Cuban forces out of their Tumpo positions without taking serious casualties. 82 Brigade began to withdraw and was replaced with Battle Group 20. ==Operation Displace==
