Winds of Destruction

by Peter John Hornby Petter-Bowyer

  It took some time for Bev to perfect a very robust smoke generator for helicopters to use as a ground-marker device. These manually activated generators were dropped over the side of helicopters from as high as 1,500 feet above ground, which subjected them to immense impact forces. It was essential to ensure each unit could survive high-speed collision with solid rock and still generate three minutes’ worth of dense white smoke. Many failures occurred and it took many weeks before reliable smoke markers became available.

  A modification to the pyrotechnic composition for existing RAMS flares achieved the intensity of flame Randy sought. Here again much trial and error was involved along the way and without Bev’s incredible effort and technical expertise we would not have been ready for the first low-level night attack on Madula Pan. This attack will be discussed shortly.

  One simple project Ron Dyer and I took on was to rectify the poor returns Lynx pilots were getting from their 37mm Sneb rockets. All we had to do was ask our engineering colleagues to manufacture in steel the same extension tubes used for phosphorus marker rockets. These tubes were then filled with RDX-TNT.

  Tests showed the heavier 37mm (boosted) rockets were noticeably slower in flight than the lighter smoke markers, but they were just as stable. More importantly the shrapnel effect of boosted 37mm SNEB showed a ten-fold improvement over standard ones. Thousands of 37mm extension pieces were produced and filled at Thornhill over the next three years.

  CS pellets

  MOST FIREFORCE ACTIONS OCCURRED ON hills, in forested areas and riverine vegetation because this is where CTs enjoyed best cover. Most of the hills (kopjes) possessed huge granite boulders and vast granite surfaces. When CTs managed to get into good cover between or under granite boulders they became a dangerous menace and were almost impossible to flush out. Cannon fire and Frantans were seldom effective and too many soldiers were killed or wounded when attempting to kill or dislodge them. On two occasions I recall dogs attempting to flush men from hiding but they were killed.

  I considered many possibilities in trying to find a way to incapacitate or force CTs into the open and even looked into firing rockets or dropping containers filled with anaesthetising fluid, but none of these ideas was practical. Then I came upon information about talc pellets impregnated with CS (teargas). I cannot recall where I read about this but remember the effects CS pellets exhibited on trials.

  Teargas grenades employ a pyrotechnic cake from which CS is released when the charge burns. The resultant gas is hot and initially visible but its spread tends to be upward and the resultant gas cloud is wholly subject to wind drift. Irritation effects are short-lived and affect some people more than others. Dogs can tolerate CS gas because they do not possess the irritable sweat glands of human skin. CS pellets act differently in that they release invisible gas over a long period of time. The unheated heavier-than-air gas spreads out at ground level and migrates into every nook and cranny. Above all its presence makes it quite impossible for any human to remain where pellets are present.

  I discussed the matter with John de Villiers and Vernon Joynt of CSIR and asked if they could produce CS pellets. They liked the concept and thought it possible providing they could establish a suitable talc powder binder to form pellets. I left the problem with them and returned to Rhodesia to design and manufacture an appropriate dispenser that would disperse the pellets over large areas. The dispensers worked well but unfortunately the CS pellets never materialised because CSIR had more urgent matters to attend to.

  Hispano cannons for Scouts

  THE SELOUS SCOUTS HAD EXTENDED their roles beyond pseudo operations within and outside the country. During May and June 1976 they conducted vehicle-borne operations across the border into Mozambique. On one excursion, they went into the Gaza Province in an attempt to stem the tide of ZANLA forces that were using the road and rail from Maputo to Malvernia. Air support for this operation was limited to one Alouette for casualty evacuation and one Lynx flying at great height to act as a radio relay between the ‘flying column’ inside Mozambique and the Scouts’ forward HQ inside Rhodesia.

  For over a year Selous Scouts’ over-border operations had been conducted with the clear understanding that no air support would be given, even if the units ran into lifethreatening situations. This restriction applied equally to operations in Botswana and Zambia. Even after the new President of Mozambique, Samora Machel, closed the border with Rhodesia on 3 March 1976 and vowed to provide full support to ZANLA, the ‘no air support’ ruling remained. Machel’s statements were, in effect, a declaration of war, but this made no difference. Political restraints on the external use of air support were almost certainly intended to keep international pressure off Prime Minister Vorster; otherwise we might have experienced further disruptions in our supplies from RSA.

  This situation was no less frustrating for the men on the ground than it was for the Air Force. We knew that Scouts had suffered the loss of Sergeant-Major Jannie Nel, killed at Mapai on 26 June 1976. In the same action, Lieutenants Dale Collett and Tim Bax were seriously wounded. Tim recovered after many months, but Dale’s bullet wound confined him to a wheelchair for life. Although I did not know the exact details, the lack of air support and possible limitation in ground firepower led me to make a telephone call to Ron Reid-Daly.

  Some time in April 1976, I had approached Major Brian Robinson at his SAS HQ to ask him if he was interested in 16 of our 20mm Hispano cannons that had been removed from four time-expired Vampires. Considering the great weight of these guns and the nature of SAS operations, Brian could see no use for them at the time, but he did not close the door on the offer. My approach to Ron Reid-Daly met with a totally different response because he was in urgent need of improved firepower for his mobile columns operating in Mozambique.

  Within an hour of the call I met with Captain Rob Warraker and a small group of Selous Scouts territorial engineers at New Sarum. With Air Force armourers and myself, the Scouts engineers lay under a Vampire to be shown how the cannons were mounted on swinging arms that allowed them to rock backwards under recoil, and forwards from the press of sturdy rear-mounted springs. This rocking action was used to retain a powerful spring in the BFM (belt-feed mechanism) that was fitted next to the cannon. The BFM was the essential component that pulled the heavy ammunition belt from the ammunition-bay and fed rounds into the gun’s breach.

  Air Force had considered mounting the cannons in purposemade swivel platforms for vehicles assigned to airfield defence, so we had a good idea of what technical work needed doing. The Scouts engineers picked up the ideas immediately and Rob Warraker, fearing we may change our minds, hastily left with the four cannon and 20,000 rounds of ammunition he signed for. In no time at all the Scouts completed the mountings and finalised range testing. Three vehicles were fitted with these cannons for a forthcoming external operation against a large base in Mozambique where ZANLA groups were assembled, armed and briefed before being launched into the Thrasher area.

  Captured CTs repeatedly referred to ‘Pungwe Base’, which they said was sited on the banks of the Pungwe River, but photo-reconnaissance along this large east-flowing river failed to find anything. Then, quite by chance, Squadron Leader Randy du Rand was returning from an unrelated Canberra task when he happened to fly directly over Pungwe Base. His navigator spotted the large camp through an opening in the cloud and rolled the cameras just before cloud obscured the ground again.

  When the JSPIS interpreters at New Sarum viewed the photographs of this large base, they were astounded to see hundreds of people gathered in a box formation around a flagpole in the centre of a large parade ground. What excited them was the fact that the flagpole itself stood at the centre of an outline of Rhodesia that was fashioned from whitewashed rocks. The word ZIMBABWE, also laid out in painted rocks, clearly identified the base as belonging to ZANLA.

  First photograph of Nyadzonya. Note the number of people mustered on the open ground. JSPIS head-count was over 800 on parade with at leas
t another 200 visible amongst the buildings. The river on the right is the Nyadzonya River.

  Ron Reid-Daly was delighted with the Air Force find that gave final proof of the large number of ZANLA in residence. The location of this base was not on the Pungwe River as reported but was on one of its south-flowing tributaries, the Nhazonia River, also known as Nyadzonya. With the position of the Pungwe Base established, the Canberra squadron flew repeated photographic sorties to monitor developments. These showed that base occupancy was increasing daily. Captured CTs continued to indicate that this was ZANLA’s primary base and their hand sketches confirmed the base layout, including the whitewashed outline of Rhodesia surrounding the word ZIMBABWE, also structure from whitewashed rocks.

  After much detailed planning for another ‘flying column’ assault, a Scouts force was authorised to attack the Nyadzonya base. But again, direct air support was disallowed. The attack was a huge success and something in excess of 2,000 armed ZANLA, plus a few FRELIMO, were killed, wounded or drowned in the Nyadzonya River. The barrage of light and heavy automatic gunfire, including high-explosive rounds from two Hispano cannons, had been devastating. (The third vehicle fitted with a Hispano cannon met with misfortune just before the raid was launched.)

  Only when the column was under attack from FRELIMO very close to the border during exfiltration, was air assistance authorised. A pair of Hunters flown by Flight Lieutenant Abrams and Air Sub-Lieutenant Lowrie neutralised troublesome FRELIMO mortar and gun-emplacements in failing light. A helicopter collected the most serious of four wounded men and a Lynx, flown by Air Lieutenant Ray Bolton assisted the column by choosing the best route for it to bundubash its way to safety inside Rhodesia.

  A Canberra photo-recce sortie was run over Nyadzonya after the attack. The resulting photographs revealed hundreds of bodies strewn across the parade ground, between the many burnt-out buildings, and in the adjacent bush. As our politicians had feared, but expected, the international press reported the action as a slaughter of innocent refugees—ZANLA having registered Nyadzonya and all its other bases as refugee centres.

  For years Rhodesia had suffered bad international press at the hands of unscrupulous sensation-seeking reporters and photographers. Even before ZANLA became effective, British reporters deliberately produced misleading articles that were supported by concocted photographs. For instance, one reporter and his photographer threw coins and sweets into rubbish bins to induce children they had gathered together into frenzied scrambling for prizes in what the children believed was a lovely game. Photographs appearing in overseas newspapers showed ‘starving children scrambling for food on the streets of Salisbury’.

  For years the residents of Salisbury had been used to the sight of many black office workers taking a lunchtime nap on the lawns of Cecil Square, a small park in central Salisbury. Overseas photographers recorded this common sight. Next day photographs appeared in UK papers under the banner headline ‘Slaughter of innocents by the Smith regime’.

  Mixed events

  1976 HAD BEEN A YEAR OF mixed events. Robert Mugabe had been installed as President of ZANU. South Africa was under increased pressure from the West following a civil uprising in Soweto. Dr Henry Kissinger, the US Secretary of State, visited South Africa as the somewhat reluctant conveyer of a joint American and British proposal for a suicidal change in political direction by Rhodesia. By highlighting western concern over the Soweto tragedy and manipulating South Africa’s power over Rhodesia, the ‘Kissinger Proposals’ were forced on our country by both Kissinger and Vorster. One component of these proposals was for the Rhodesian Government to participate in negotiations with ZANU and ZAPU in what was to become the Geneva Conference. Both ZANU and ZAPU had been pressurised into accepting the ‘Kissinger Proposals’ by the Frontline States though they disliked the conditions as much as the Rhodesian Government. Anyway the Geneva Conference, chaired by Britain’s lacklustre Ivor Richard, ended in total failure.

  During the year the Air Force lost men and machines in offensive actions and accidents. Without exception they were superb individuals whose loss emphasised the sheer wastefulness of war and the high cost in lives from accidents associated with war.

  On 16 February, Squadron Leader Rusty Routledge was killed when a young SAAF pilot attempted to overshoot his overloaded Cessna 185, following a botched approach for landing at Perrem Airfield near Umtali. The aircraft stalled at low level and all three souls on board died when it ploughed into the ground.

  On 10 June, following a FRELIMO cross-border attack on Zona Tea Estate inside Rhodesia, a Hunter flown by Flight Lieutenant Tudor Thomas received a fluke bullet strike during a rocket attack on offending forces at Espungabera in Mozambique. The bullet severed a hydraulic line resulting in the loss of all hydraulic fluid. In fading light Tudor returned to Thornhill where the OC Flying Wing, Wing Commander Keith Corrans, ordered him to abandon his aircraft. This was because Keith did not want Tudor to attempt a very fast, flapless landing at night with his flight controls in manual mode and too many other associated problems. Main undercarriage legs were drooped but not locked whereas the nose wheel was down and locked. In addition the air brake was half-extended and full left aileron was needed to hold wings level at 210 knots. Undoubtedly the slightest error would have been fatal.

  Tudor positioned wide downwind for runway 13, trimmed fully nose-down and ejected. As intended, the Hunter crashed in open farmlands and Tudor escaped with little more than a bruised back. The loss of this Hunter was devastating because it reduced our Hunter strength to ten aircraft.

  On 13 June 1976, a Z-Car gunner (name forgotten) was killed whilst firing at CTs in a Fireforce action. Then on 18 July, air-gunner Sergeant J.P. Graham was killed in the same way in the Inyanga area. Six weeks later, on 1 September, airgunner Sergeant Belsted was killed in yet another Fireforce action in a helicopter flown by Flight Lieutenant Ian Harvey.

  Flight Lieutenant ‘Starry’ Stevens died the very next day when he flew into an air ambush deliberately prepared by FRELIMO forces acting in support of their ZANLA colleagues. A group of CTs made their presence purposely known to induce a hot-pursuit operation into Mozambique. Their path ran along the base of a 1,200-foot-high west-to-east ridge along which FRELIMO had set up a number of heavycalibre anti-aircraft guns to take on aircraft they knew would come. Starry’s Lynx stood no chance as it passed close to and level with the guns.

  On 11 August, as a direct result of the Selous Scouts attack on Nyadzonya, FRELIMO retaliated by mounting a mortar attack on the city of Umtali. Superficial damage was caused to buildings in the eastern suburbs of Greenside and Darlington. Fortunately, not a single casualty was reported and very little structural damage occurred.

  On 21 October, Flight Lieutenant Roy Hulley was flying a Vampire FB9 on a routine gunnery sortie at Kutanga Range. He had completed a pass on his target and was running low-level on the downwind leg to position for another attack when his aircraft suddenly dived into the ground, narrowly missing the tented base of a small Army training camp. It was assumed that Roy might have been reaching for something he had dropped on the cockpit floor because there was no other explanation for this sad occurrence. It seems more likely, however, that seat-locking on the height adjusting mechanism disengaged in turbulence dropping the seat so low as to place Roy’s eyes below the cockpit combing. This technical difficulty became well known before the FB9s were withdrawn from service.

  Larger groups of CTs were crossing the border when, on 15 November, a Fireforce action in the Honde Valley resulted in one CT group being cornered on a long, heavily forested hill. At the end of a long day of fighting, thirty-one CT bodies were counted. This was the largest number of kills in a single internal action to date. Regrettably, three weeks later this action brought about a CT reprisal with the murder of twentyseven workers on nearby Katiyo Tea Estate.

  Although brutal murders by CTs were commonplace, this one was unusual and difficult to understand, because the victims were Mozambican mig
rant workers. FRELIMO had made it clear to ZANLA that Mozambican people were royal game, never to be touched, no matter where they were. Yet the CT gang visited this workers’ compound after sunset and went about their business in their usual way.

  They rounded everyone up and, whilst getting high on dagga (marijuana), they demanded and consumed all the food and beer the villagers possessed. The headman was then tied up and forced to kneel in the sight of all his followers. Death only followed after the helpless old man had been forced to eat his own ears and nose which, despite his screams for mercy, had been brutally hacked from his head. His lips were then cut off before the fatal thrust of a bayonet released him from his agony. Not content, the CTs grabbed a baby from its mother and ordered another woman to batter the child to death with a stick. The horrified mother saw this all happening before she was raped by every CT and then bayoneted to death. Only then did indiscriminate firing kill another twenty-four innocent souls together with all their prized cattle.

  On a lighter note, I received visitations from a few Americans during the year. One of these was an arms dealer. He was a neat, dapper, dark-haired fellow whose good looks and quiet manner gave no hint of his sadistic nature. He hoped to interest me in a new type of bullet that he could supply for any calibre ammunition of my choosing. The 8mm rounds he showed me looked and felt quite normal. However, the projectile consisted of a light outer casing within which were tiny tightly packed steel slivers. The American told me that upon impact with anything, the casing yielded and released the slivers in a highenergy, fan-like shower. A single strike anywhere on a human body created such trauma that death was virtually guaranteed. The man told of this awful killing device with such passion and enjoyed the gory supporting photographs so much, that he had my blood boiling. I kicked him out of my office saying we had no interest in such dastardly devices. However, when he was gone, I wondered why I had been so put out by the man and this style of killing when I myself was so tied up in developing and producing a whole range of very unpleasant killing devices.
