We were often required to carry out some pretty strange missions during the war and the one I am going to describe to you now is just one of them.

At the time I was posted to 4 Independent Company, an Infantry unit, located in a town called Wankie. I was responsible for running the 1 Engineer Squadron operations room. Those of you who are familiar with this base will remember that it was on top of a hill and one should not confuse the location with the old 1 Independent Company base on the left hand side of the main road as you left Wankie, travelling towards Victoria Falls.

We had a good set-up in Wankie that comprised of four offices, one of which was my sleeping quarters, another the operations room itself, one for my Sappers to live in, and one for Engineer stores. I had three Sappers under command who manned the radios and carried out other duties to support our little HQ and we were a rather happy bunch.

Our primary task was to maintain and support our Engineer callsigns in the Operation Tangent area and these consisted of Troop strength sub-units based at Deka and Victoria Falls. In addition to this we also had a responsibility to provide Engineer support to the operational efforts of the Officer Commanding 4 Independent Company whenever required.

The map below shows the area of our responsibility, including Wankie (now renamed Hwange), Deka and Victoria Falls:

This map below shows what is left of the 4 Independent Company base today – indicating where the Engineers were located (if my memory serves me correctly):

On this specific day I was called to the radio by our duty operator, who informed me that it was I Engineer Squadron Headquarters (Callsign 1) looking for me (Callsign 11). I picked-up the hand-set and called them up and was surprised that the Commanding Officer (Sunray) was on the other end. I had therefore either committed some high-level violation, or he had some dodgy mission for me. Luckily it was the latter, but if I had known what the mission was I would not have been so relieved as it turned into a badly resourced and dangerous task that to this day I cannot fathom the logic of. Anyway you can judge for yourself – read on.

Intelligence collected over the years by our spooks had led to the assumption that the gooks did not always navigate with traditional methods, meaning map and compass with time and distance (no GPS in those days). The reasons for this ranged from lack of navigation training to possibly a lack of equipment. To improvise they would instead use a number of known prominent landmarks that they used for navigating from point A to point B. Ingenious, simple, and it worked. These landmarks could be buildings, large trees, fence-lines, river junctions, cross-roads and so forth – anything that could be easily identified and confirmed. They also used T-junctions in roads – and it was one of these features that I was tasked to make uncomfortable for them. Working on “hot” intelligence my mission was to take a number of R2M1/2 anti-personnel mines and a single TM46 anti-vehicle mine to booby trap a certain T-junction in our area of operations (I cannot remember the exact location but there was also a trading store right at the junction). We would also take 2 rolls of detonating cord, plastic explosives and a pressure release switch (number 6) – and lots of black insulation tape.

“Hot” intelligence normally meant that there was credible evidence from sources that imminently, there would either be an attack, gooks crossing into Rhodesia, or movement of gooks within a known area. It therefore also meant that the mission would need to be carried out covertly and at pace. This was going to be challenging as we had been given little pre-warning and all I had was 24 hours to complete the mission or the opportunity would be gone. The only information that I was given regarding this mission was that a group of terrorists was going to be using a certain T-junction as a navigation point on their route to other parts of the operational area. Our job was to stop them at the T-junction by either eliminating them or disrupting their plans.

With the benefit of hindsight, laying a booby-trap was not a very clever idea from the start – for one it would take time to mobilise to the area and to set the trap, and secondly, a well placed ambush would have been a far better (and quicker) option to my way of thinking. At the time though, I got behind the plan and proceeded as instructed.

Due to the fact that we were supporting minefield maintenance teams at Deka and Victoria Falls, we had personnel mines in the 4 Independent Company magazine as well as plastic explosives and detonating cord. The pressure release switch and insulating tape we had in our Engineer store – so we were at least prepared equipment-wise. I was to be driven to an area close to the T-junction and accompanied by an infantry call-sign and one of my Sappers during the actual laying phase. This meant it was just me and a single Sapper (lets call him Moyo) laying the traps while the infantry stick would keep their eyes open for bad-guys. We had packed everything into back-packs to make carrying all of the kit easier – all except the vehicle mine which I carried by hand after collecting it from Wankie Special Branch.

On the way to our drop-off point I wondered how were we to lay this booby-trap without being seen or heard. Considering that there was a trading store right in the middle of the target area that was sure to be quite busy in the daytime, with surely some of the customers being gook sympathisers, or Mujibas (informers, usually youths who supported the gooks). We were being forced to do this at night – not a very clever idea as laying mines in the daytime is dangerous enough as it is – at night its just plain silly and not recommended.

We had stopped some way from the target and done our best to camouflage our vehicles and settled down in an all-round defence until darkness fell. Some of us slept……I’m sure that I did anyway.

I awoke in pitch darkness and there was movement all around me. I checked my watch and it was probably around 2100 or 2200 – something like that anyway. We had already planned to walk into the target area and we hoisted our packs and fell into a single file formation with the infantry who would be navigating us in. We were going to approach the target from the north and this would bring us in at the top of the long leg of the T-junction and on high ground – the road sloped downwards quite steeply to the actual junction itself, and the trading store. Please see my drawing below for a better idea of what the ground was like and what we were going to be doing booby-trap wise.

The mines that we used looked like these:

R2M2

TM46 anti-vehicle mine – (unknown copyright holders and apologies in advance)

Once we had arrived at the top of the hill and neared the road we took up positions from where we could observe the store and road for any movement or other activity. It was actually very quiet and strangely peaceful, and after giving it another 15 minutes or so I let the infantry stick leader know that we would commence laying the trap – he nodded and put his troops in as good a position as possible to offer covering fire for us to withdraw from the road if necessary.

Moyo, as a trained Combat Engineer would lay the mines on one side of the road and I would do the other. I would also lay the TM46 at the T-junction and fit the pressure-release switch as an anti-handling device. The plan was to ensure that if anyone tried to lift the mine it would detonate.

Laying the TM46 was hard work as besides the actual excavating of the hole and setting the pressure-release switch, I also needed to run a detonating cord line to the where the first anti-personnel mines would be laid on the verges. It was a complicated and tricky set-up but the best we could do under the circumstances and time given to us. Laying the anti-personnel mines was just as difficult as the verges of the road were hard packed and covered in small pebbles that made digging and covering the mines extremely dangerous. One pebble or clump of soil landing on a mine would set the whole lot off. Please bear in mind that every mine was connected to the next mine with detonating cord. The idea being that if any of the anti-personnel were activated there would be a mighty big bang and hopefully the gooks would take some pain.

I’m not sure how long the entire laying operation took but it was still dark by the time we finished. I will say it again that this was a very dangerous task that we had been given. Laying mines in the darkness is scary stuff, and the terrain made things more uncomfortable than ever – the soil was unforgiving and hard as hell – I know we were making enough noise to wake the dead and I am pretty sure that we had compromised ourselves over and over. The whole thing was pointless the more I looked at it and by the time we were finished it would have been a foolish move to double check everything, as I should have.

Imagine this:

  • each anti-personnel mine had to have a two turns of detonating cord wrapped around it, armed and then covered
  • a small channel needed to be dug between each mine to connect them to a common ringmain – each time we done this we were tampering with a number of fully armed mines
  • working amongst the rocks and pebbles made covering mines difficult, especially in the dark
  • ensuring everything was covered and concealed to avoid discovery was practically impossible in the dark
  • working around fully armed mines, slipping and taking mis-steps is an accident waiting to happen

At the end of the day we done the best that we could and left the area by a different route with the infantry leading once again. Arriving at our vehicles it was time for a quick cup of coffee and then we were out of there by first light. I was looking forward to putting this one behind me and today I really consider this to have been one of the most pointless, unproductive and dangerous tasks I have ever had to carry out, not only from a personal perspective but also for the troops I was responsible for.

I never ever found out if the trap was sprung, and if it was by what or who? Terrorists, or an innocent civilian – or livestock? This is the danger with these devices – they know not friend or foe, killing or maiming anyone or anything that sets them off. The idea was for an aircraft to fly over the target now and again and check for a crater from the TM46 at the T-junction that would confirm detonation……..I’m not sure if these flights took place at all to be honest. Aircraft were needed elsewhere and certainly not to go and check a T-junction, so the result remains a mystery to me till this day.

To finish this one off let me just say this; booby-traps have their place in warfare, however they should be planned correctly, deployed with sufficient time to ensure the safety of the layer, and never used as a stand-alone substitute for a well-laid ambush. The way we were told to do this one could easily have cost own forces casualties and the planners should be ashamed of themselves – knee-jerking desk-jockeys with little insight into how things actually work on the ground are very, very dangerous indeed.

Thank goodness that the Rhodesian Corps of Engineers were some of the best trained Sappers in the world. Its the reason I am still here and able to write this blog.

The definition of a Booby-Trap according to the Rhodesian Corps of Engineers (RhE) training pamphlet was as follows:

A booby trap is a cunning contrivance, usually of an explosive and lethal nature, designed to catch the unwary enemy; a savage practical joke. It is aimed directly at the reduction of morale and mobility, both of which are vitally important to success in war.“.

In this post I would like to recall two occasions where I was tasked by my higher HQ to lay Booby-Traps. These operations were to take place in the Operation Tangent area and were to be sighted in such a way that terrorists would be well into the kill-zone before the traps were initiated, meaning that we were going for maximum gook casualties. Concealment of the entire set-up was therefore of critical importance, and this includes clandestine insertion of the Booby-Trap team, as we knew that there were eyes and ears everywhere in the bush. We therefore had to apply counter surveillance techniques from insertion to extraction as it is pointless to lay a Booby-Trap that can be seen, or the laying team are observed moving into the target area.

Without going into too much detail, Booby-Traps can be initiated (set-off) by a number of actions, the most popular at the time being the application of pressure, the release of pressure, pull, pull (or tension) release, or the application of some form of Delay. There are many other ways that Booby-Traps can be initiated but I am not going to cover these here. We had specially manufactured devices known as switches, available to us, however for the specific tasks that I was to lead on we would be using Pressure switches only. In other words the required action for success was for someone or something to stand on the pressure switch for the Booby-Trap to detonate. Please note that I used the term “someone or something” as these devices cannot tell friend from foe and would therefore activate the trap regardless of who or what applied the pressure. Sadly animals and friendly forces have been collateral damage to these devices on a number of occasions causing death or injury. The following illustrations show the abovementioned methods in simple to understand detail:

Looking at the previous paragraphs, my readers will appreciate that there are a number of fundamental pre-requisites for a successful Booby-Trap result. One does not simply pick a spot on a map and Booby-Trap it and there are a number of basic principles that we observed when sighting and laying Booby-Traps, and these are as follows:

  1. Concealment: The charges and mechanisms must be concealed or made to resemble some harmless object. The surroundings should be disturbed as little as possible and all signs of preparation should be concealed or removed.
  2. Constricted Localities: The more constricted the site in which a trap is laid the more chance there is of its being sprung and the greater the difficulty of detection and clearance. Any form of defile is therefore a suitable site for boobytraps.
  3. Concentration of Traps: Traps should be laid, whenever possible, in considerable concentrations to reduce the chances of finding them all without springing some. Dummies should be used freely.
  4. Double bluff: An obvious trap may be used to mask a well concealed trap near by.
  5. Inconvenience: Traps may be operated by the removal of obstacles such as road blocks and demolitions, or of furniture or litter in dug-outs or buildings, particularly if these are suitable for headquarters.
  6. Curiosity: The handling of souvenirs, pictures, food and drink containers, musical instruments, weapons, etc, may operate a trap.
  7. Everyday operations: Traps may be operated by opening or closing doors or windows, using telephones or electric light switches etc.
  8. Attraction: Delay-action or incendiary bombs may attract personnel to a booby trapped site.
  9. Alternative methods of firing: A trap may be provided with two or more methods of firing.
  10. Variety: As many different types as possible should be employed in any one locality.

Before continuing I would like to be clear on what I was expected to achieve on both missions and you will note that this ties in closely with the foregoing paragraphs:

  1. Inflict maximum casualties on the enemy.
  2. Use Pressure as the initiating action.
  3. Use of the following Principles – Concealment, Constricted Localities, Concentration of Traps, Alternative methods of firing and Variety.
  4. Covert infiltration to laying site
  5. Operational Security (Opsec)

A brief description of the two missions are as follows:

Mission 1

  1. Operational Area: Tangent
  2. Environment: Forest
  3. Type of Booby-Trap: Multi-device, pressure operated
  4. Concealment method: Existing vegetation
  5. Explosives to be used: Date expired Air Force and Army ordnance
  6. Insertion: Vehicle and night-march

Mission 2

  1. Operational Area: Tangent
  2. Environment: Existing dirt road
  3. Type of Booby-Trap: Multi-device, pressure operated
  4. Concealment method: Existing soil on dirt road
  5. Explosives to be used: Anti-personnel and anti-vehicle mines
  6. Insertion: Boat and night-march

In the next post I will describe in detail Mission 1 and Mission 2.

DEKA ARMY BASE: LATE AFTERNOON

Conversation between Camp OC and ourselves:

“I want you two wasters to get your boat ready for a night operation.  You are to take your boat to this grid reference (him indicating on the map) and wait there for someone to make contact with you.  You will need spare fuel tanks, 24 hours rations and full ammo.  I cannot tell you anything else but make sure you get there just as last light falls and don’t fuck up on the position I just gave you”

That was it.  Short and to the point.

It quickly became time to go.  As Tony and I climbed into the back of the Mercedes 25 Troop Carrying Vehicle (TCV) we looked at each other and wondered what the hell this was all about.  We didn’t even know who we were supposed to meet and more importantly, what for.  The driver fired the Unimog up and with a characteristic torque-induced jerk we were off, easing through the camp entrance, and then turning sharp left onto the road to Sibankwazi.  To our boat……..and the Zambezi River.

I had looked at the Ops Room map as the Captain briefed us and taken down the grid reference we were headed for.  As far as my memory serves me it was at the position marked SAS pick-up position on the map shown below, near to Mapeta Island:

Ops Mulola

Tony and I had worked the time and distance calculation to get us to the Rendezvous Point (RV) just as last light was coming on.  We were both edgy and rather subdued on the journey down to the boat, each of us respecting one another’s silence.  Travelling the Zambezi River during the day was a challenge at the best of times, always having to ensure that we never strayed across the international boundary (Rhodesia/Zambia), which was an invisible line running up and down the river, but not necessarily in the middle.  We were now going to be travelling on the water towards dusk and more than likely in darkness if our suspicions were right.  Logic told us that no one would want us to meet them with a boat if they were not going to use it.  We were spot on!

We had trained to work on the Zambezi River at night and knew that the landmarks that we used for daytime navigation, could also be used at night.  We always chose high features that would silhouette easily against the sky or stars for navigation.  Simply put we would know what feature to point our bows at and which feature our stern should be pointing at to stay safe.  Quite an easy task in daylight but in darkness a mans eyes play games, confusing the mind as to what feature is what, what is true and what is false.  Making you doubt your own judgement, possibly leading you into a bad place.  No GPS in those days…….maps, compass, eyes and dead reckoning.  I loved that kind of navigating though.  Seat of the pants stuff and a small victory when you arrived at the right location.

We debussed at Sibankwazi, close to our boat.  First on the agenda was to check in with the British South African Police (BSAP) personnel at the camp and let them know we were going out on the water.  There was nothing to tell really, just that we were going up river and would stay in comms with them.  We took comfort in knowing they would come out and help us if the shit hit the fan.  They were good lads and always watched our backs.  And they had nice, shiny fast boats with big guns on.

Tony and I finished our preparations, cleaning the inside of the boat, filling fuel tanks (2 per engine), checking our small supply of boat spares, running up the engines (which had no covers), checking radio comms with the police and Deka Base, and checking our personal weapons and kit.  I would take us on the outward leg and Tony would bring us back.  What happened in between we would share.

The picture below shows Sappers carrying out typical boat preparation activities.  This is the exact same type of boat we were using on this mission (Basil Preston):

Typical boat preps

It was time to move out.  I moved the throttles to the start position and made sure the engines were in neutral.  Tony pumped the primer balls to get juice into the carbs, wound the starting rope around the first engine and pulled it.  The engine fired and I adjusted the throttle to a gentle idle.  He started the second engine and we were ready.  I let the two engines idle for a minute or two while Tony made sure water was being expelled from the cooling system outlets.

I gave Tony a thumbs up and he slipped the mooring line.  I moved both engines to reverse and we began gently edging astern and away from land.  Once far enough out I put the engines in forward gear, pushed up the revs and pointed our bows north-west…..into the gathering gloom……we were on our way.

The picture below gives an idea of the Zambezi River at night……..a very dodgy place to be, especially if there was no moon:

The previous posts focussing on laying Cordon Sanitaire took more time and research than I thought they would.  These operations were truly the Rhodesian Corps of Engineers own private battle within the Rhodesian Bush War.  Thanks to the input of former Rhodesian Sappers (and in some cases, non-Sappers), I think we have managed to bring those challenging days to life once again.  As I mentioned in a foregoing post, I feel enriched and privileged to have been part of these operations.  It was and still is an honour to have shared the hardships and dangers with that very special Band of Brothers.  Mukumbura will never be forgotten.

There will be more on Cordon Sanitaire later but now is not the time.  These future posts will fall under the main title of Cordon Sanitaire Phase 2 (Minefield Maintenance).  In so many ways this was the biggest challenge we had as a Corps.  The dangers faced by maintenance crews were far greater than those faced during the laying of the Cordon which in relation to this blog was Phase 1.  Indeed, the majority of Rhodesian Engineer fatalities and serious injuries were a result of minefield maintenance operations.  As a Regular Army sergeant I commanded minefield maintenance operations at both the Deka Minefield and the Victoria Falls Encirclement and will discuss both of these at a later stage.

For now it is time to say farewell to Operation Hurricane as we move to the Operation Tangent area (see map below).

The next post will start off with my recollections as a boat operator on the Zambezi River, based at Deka Camp and operating out of Sibankwazi with the British South Africa Police (BSAP).

Mukumbura………to any Rhodesian Sapper worth his/her salt the name conjures up Cordon Sanitaire operations.  Indeed to most of us this was the Mother of all Rhodesian Cordon Sanitaire operations.  However there were other areas where we laid mines, usually along the conventional lines of what I have described previously, but also some in more unconventional ways (will describe these in future posts).

Here is a diagram showing the extent of Cordon Sanitaire operations throughout Rhodesia.  It also shows the various operational areas:

Corsan Map_All

I would like to point out the following:

1.  This map is not to scale

2.  The information is to the best of my knowledge/memory correct (but fairly accurate and I do not suggest walking on the red bits).

3.  Red bits (added by me) denote armed Cordon Sanitaire strips.

4.  Base map courtesy of shelf3d.

Known mined areas:

1.  220 kilometers: Victoria Falls to Mlibizi

2.  359 kilometers: Musengetsi to Nyamapanda to Ruwenya

3.  72 kilometers: Junction Gate to Jersey Tea Estate to Muzite Mission

4.  50 kilometers: Stapleford Forest to Umtali

5.  61 kilometers: Malvernia/Villa Salazar to Crooks Corner

6.  +-1 kilometer: Kariba Power Station

Not all of the areas above were laid to the same pattern.  Some were standard pattern, others double-density, and some contained additional trip-wire operated fragmentation stake-mines.  The double-density/trip-wire minefields were the most dangerous for us to work in, especially when carrying out minefield maintenance tasks.  I will show diagrams of these variants in future posts to give you a better idea what they looked like and what we were up against.

The above information (Rupiah) is probably reasonably accurate distance wise but definitely does not account for what I will call “other” mined/booby-trapped areas.  I know these “other” areas exist because I laid some of them while serving on special operations.  My conclusion regarding these “other” areas is therefore that they remain unknown and uncleared.
