When they came in sight, the guerrilla forces did not appear to be expecting any opposition. As they advanced, they barely bothered to adopt tactical formation at all, but trudged along behind the tanks, weapons slung over shoulders, talking, chewing, laughing, the gap between the two parties a mere 100 metres. As he watched them coming, Van der Horst was thinking that his plan should work.
As a plan, it was good. But military plans, as von Moltke observed, rarely survive contact with the enemy. In this case the seemingly unwary enemy suddenly took the whole affair into their own hands. When the guerrilla column was no more than 800 metres away from the ambush, the two tanks deployed to either side of the track and opened fire, first with machine-guns, then with high-explosive shells, on the derelict farm buildings. They were well out of range of Van der Horst’s rocket launchers. The guerrilla foot soldiers rapidly dispersed on either side of the tanks and went to earth. Van der Horst gave a quick order over his radio: “Keep in cover and return fire with mortars and machine-guns. Leading group at five minutes’ notice to move back to get behind them.”
The tanks kept up a steady fire and seemed quite impervious to the machine guns now engaging them. Meanwhile, to Van der Horst’s concern, the enemy guerrillas seemed to be crawling through the bush to the north of them in an obvious attempt to outflank his own position. It would be foolhardy to try to outface tank fire and allow his force to be pinned down while the guerrillas crept ever closer. He still had one advantage over the enemy — speed. He spoke into the radio again. “Cancel last order. Rear group prepare to mount in Landrovers and move south in fifteen minutes; leading group prepare to give covering fire; my group will follow rear group, covered by leading group, and we will leapfrog back to agreed rendezvous Charlie. Maximum covering fire throughout move. Mortar fire to switch now to Hill 102. Leading group to withdraw when my group established at Charlie. Move on my orders.”
From a concealed position of great strength, with the expectation of gaining both surprise and success, Van der Horst was obliged to resort to defence, evasion and retreat. And all because he had no anti-tank weapons of sufficient range. It was a lesson well learned, and would not have to be relearned, as before long his unit and others like it would be equipped with the longer-range
Even when the invading columns from Mozambique did meet with some success in their advances, they threw away their advantage by their savagery to the black inhabitants they claimed to have come to deliver. The Cuban proxy leaders of the FRELIMO bands were men to whom the death or mutilation of wholly innocent men and women was of no moment. Such was the short-sightedness and vindictiveness of the invading army’s leaders that they were ruthless where they should have been conciliatory, and — in the case of their own members who revelled in excesses — tolerant where they should have been stern.
The invasion from Mozambique was held, but CASPA would not lightly give up the battle. Guerrilla forces from Botswana were advancing deep into enemy territory, reinforced by incursions from Zimbabwe. But what was rapidly becoming clear was that South Africa was holding on.
Long before it was all over, the USSR had wholly ceased to be in control of anything that was happening either in the Middle East or in Southern Africa. Orders from Moscow, growing in confusion and inadequacy in the last few days of August 1985, had, by the end of the month, virtually ceased.
