Cordon Sanitaire: Personal Experiences (2: Vic Thackwray)
October 19, 2014
As mentioned in my previous post we will continue with the personal recollections of some of those that worked on Cordon Sanitaire. In this post we have accounts from Vic Thackwray, another former Commanding Officer of mine. I had the pleasure to work with Vic in the Rhodesian Army (RhE), the South African Defence Force (SADF (SAEC)), and also in the private sector after we had both ended our military careers. Vic and I remain close friends and I wish to thank him here publicly for all of the help and sage advice he has given me over the years, and will probably also need to do in the future. I am bound to ask him something and he always responds rapidly and with a genuine willingness. Thanks for everything Vic…..you are one of a kind.
The picture below shows Vic (left, saluting with the sword) as Parade Commander at the Last Official Parade of the Rhodesia Corps of Engineers in 1979……..a sad day indeed and the end of an era but how proud he must have been!!
Vic takes up the post from here…………starting with an interesting and sobering Cordon Sanitaire Fact Sheet:
‘CORDON SANITAIRE’ FACT SHEET
The following illustrates my involvement with the Rhodesian Cordon Sanitaire.
- My initial deployment to Cordon Sanitaire was to take over from Terry Griffin (see previous post) who had trained the first mine laying teams in Mukumbura.
- My second in command was a Corporal Charlie MacQuillan who had recently attested into the Rhodesian Corps of Engineers from the British Army.
- We commenced laying the Portuguese M969 mine. This was followed by the South African R2M1 mine, the South African R2M2 mine, the Rhodesian Engineer manufactured RAP mine (commonly referred to as the ‘Carrot Mine’), and the Italian VS50 mine.
- The Cordon concept was based on the Israeli Defence Force minefield which separates Lebanon from Israel and is called the ‘Blue Line’, the electronics used in Israel were used for the first 50 km or so in Rhodesia but was soon ‘binned’ for financial reasons coupled with the constant triggering of the system by wild animals.
- The total length of the combined minefields is 696 km
- The density of mines was 3,000 mines per kilometer with 300 ploughshares per kilometer for approx 500 kilometers.
- A committee was inaugurated comprising the SADF, the Rhodesian Army, and elements of CSIR in SA and was called the ‘Geisha Committee’. It was formed to discuss, workshop and plan all mine action activities between the two countries.
- One of the senior CSIR members, (name removed) was instrumental in the design and manufacture of the R2M1 and R2M2 AP mines. I was tasked to assist on the ground in the Mukumbura area and established a ‘Seed Minefield’ within our minefield. In this area we laid many mines at predetermined depths and other technical data. On frequent occasions the Professor would travel to the field and I would be instructed to remove selected mines for observation and assessment.
- Accidents involving own troops during laying, maintenance and some clearance numbered 97, of which the majority were traumatic amputations of one leg, and 1 member both legs, (1 above and 1 below the knee) (Sgt. Willem Snyder). Several of the 96 members lost hands, fingers and eyes, 1 unfortunate member Spr Ndlovu lost both hands and blinded in both eyes during the arming of a plough share. The deaths of members numbered 30, however, this figure is not confirmed but estimated by me and several other officers of the Corps. he majority of accidents and ALL the deaths are attributable to the Maintenance phase of the Cordon. I am aware of members being killed when the point Sapper walking down a safe lane was confronted by a snake, normally a Black Mamba or Cobra and he just ran blindly into the minefield and subsequently triggered the trip wire of a plough share instantly dying and often a few of the maintenance team were injured by shrapnel. Additionally other members were killed or severely injured when replacing plough shares during which the 30 metre trip wire was hit by Doves, guinea fowl, small antelope, and turkey buzzards. In the Umtali forest areas where I spent considerable time, several members were injured or killed when the plough share was triggered by falling bark from Gum trees as the Cordon went through many Gum Tree plantations. Again in the Umtali area some 5 accidents were attributed to terrain problems, whilst maintaining the minefield the 15-20 cm. thick soggy/wet leaf mould caused the members to slip/slide and subsequently hit a mine on their rapid descent. One young Sapper lost his leg when he foolishly attempted to retrieve a set of Kudu trophy Horns in the Northern minefield.
- The Cordon, in 99% of cases employed the International Border as the Enemy fence, for obvious political reasons.
- When the terrain dictated that the Cordon could not follow the Border, the proposed route of the field was assessed and this information subjected to a high level detailed Military Appreciation. Changing the minefield routing obviously required high level Political input as it involved, Private land, farms, forestry, National parks, Police, Internal Affairs, and Tribal burial grounds, to mention a few. This appreciation and request was forwarded to Parliament via Engineer Directorate to Army Commander to COMOPS for approval. The agreed rerouting on the Rhodesian side of the border together with detailed maps of the new routing was then subsequently issued from Engineer Directorate.
- The Cordon including all maps, diagrams, drawings, mine stocks and all reports etc., was officially handed over to the New ZANU Commander of the Zimbabwe Corps of Engineers over period April 1980 to December 1980.
Vic continues with anecdotes he recalls from the time:
During the maintenance of the Cordon Sanitaire, we frequently had to deal with wounded terrorists in the field, on one occasion near the Mazoe river bridge on the Northern border with Mocambique we were informed of four terrorists injured in the field, I proceeded with my team, ably protected by “Dads Army” , (the over 50-year-old soldiers)!
On arrival I deployed the protection troops to give me covering fire, gave them strict orders on the rules of engagement and proceeded to clear into the field.
Of the four terrorists, one dead, one youth (more a porter of equipment than a combatant), and two combatants, one had lost both feet and the other, one foot. Both with AK rifles close by and lying with their injuries slightly elevated on packs to reduce pain and bleeding. I gave them the usual warning that if they moved during my clearance in to save them, the troops would not hesitate to take them out.
All prepared, focused and fully hyped, I commenced clearance, when suddenly out of the blue, one of the “old soldiers”, a bank manager, called out to me in a loud and very posh voice:
Quote
“ I say sir, there is no threat here, it appears that all these chaps have been defe(e)ated”
unquote .
That just cracked me up, I needed a few minutes to regain my composure, and focus before resuming clearance.
And another…………………….
First Version of the Ploughshare
Based with Major Henk Meyer 1st. Battalion RLI at Mukumbura,
I had been tasked by Colonel Parker (affectionately called the ‘King’) who was based at Mount Darwin to strengthen the minefield over a certain area as they were expecting a thrust from Mocambique.
I installed 30 trip wire operated devices (First version of the ploughshare, using old pull switch devices.
Major Henk Meyer instructed me to show and explain the procedure to Captain Keith Sampson RhE., and a Selous Scouts Officer Major John Murphy (ex American Military), with parting words from Major Henk, ‘be careful Thackwray’.
I was dressed in Veldskoens, no socks, camo shorts, camo shirt, chest webbing, Camo floppy hat, water bottles and rifle .
We walked about 2 km along the fence with army protection on our left hand side, crossed the minefield at my clearance lane into Mocambique and walked 400 metres along the minefield fence to the position of the devices.
At a safe distance from the devices, I instructed them to wait at the fence whilst I made the device safe, I went in, removed 2 of the 3 ‘keeper mines’ from the base of the device and removed the detonator from the trip wire device, placing the detonator below my lower legs .
I commenced describing the device when (according to the protection force members) a bird some 20 metres down, flew into the trip wire, the detonator blew and I received detonator shrapnel, mainly to face, head, arms, legs and lost an eardrum, fortunately I had my prescription glasses on.
The two very agitated visitors were trying to come through the fence to assist me, I calmed them down stating that I was OK just a little blood, Major John Murphy then said words to the effect that ‘Rhodesians had big balls’. With ringing in my ears I only remember hearing the word balls, to which I immediately and instinctively checked my 6 o’ clock position, all was found to be good and this reaction was enjoyed by my visitors.
I relaid the 2 mines around the base and we walked back the 400 metres and along the 2 km road to base, it was amusing because all the supporting troops were staring at this walking bloodied apparition.
We finally arrived back at RLI base and my shoes were swimming in blood I was an apparition to behold, Major Henk Meyer was not amused and taking off his beret swiped me with it, saying “I told you to be careful Thackwray and what am I going to tell the King (Colonel Parker)”?.
I was casevaced to salisbury two days later.
Below I have included pictures from Vics contributions showing the types of mines he mentions :
Portuguese M969
South African R2M2 (R2M1 was very similar in overall design but had a different ignitor)
Rhodesian Carrot Mine (RAP)
Some of the items may vary in colour from what the Cordon Sanitaire veterans remember but the general shape and design are spot on.
I would like to thank Vic once again for his input here

Cordon Sanitaire: Defoliation Efforts
July 26, 2014
I never realised how challenging it would be to get information on Rhodesian Army defoliation efforts on Cordon Sanitaire or anywhere else for that matter. One of the main reasons for this is that these activities took place, and were more or less completed by the time I joined the army. It is disappointing that so little is known of these activities and I apologise in advance for the scant information at hand. This is definitely one of those posts where I could do with all the help I can get.
However I have managed to cobble some data together thanks to Terry Griffin and Vic Thackwray (a big thanks to both of them who incidentally were also both my Commanding Officers, at different times of course), and also a number of publications. It would however seem that very little information on this aspect is available.
As a starter to this post it is probably useful for some readers to have a better understanding of what defoliation is all about, why it is used during military operations, the main methodologies used, and historical results both positive and negative. Without question the use of defoliant by the US military during the Vietnam War (and Korea before that) is the best example of these activities and they are well documented, mainly for all the wrong reasons.
A short preamble will therefore follow and we will then look at Rhodesian Army efforts according to my understanding of things.
Chemical Defoliation
Probably the most well-known chemical defoliant used to date is Agent Orange.
Agent Orange was a powerful mixture of chemical defoliant used by U.S. military forces during the Vietnam War to eliminate forest cover for North Vietnamese and Viet Cong troops, as well as crops that might be used to feed them. The U.S. program of defoliation, codenamed Operation Ranch Hand (http://en.wikipedia.org/wiki/Operation_Ranch_Hand), sprayed more than 19 million gallons of herbicides over 4.5 million acres of land in Vietnam from 1961 to 1972. Agent Orange, which contained the chemical dioxin, was the most commonly used of the herbicide mixtures, and the most effective. It was later revealed to cause serious health issues–including tumors, birth defects, rashes, psychological symptoms and cancer–among returning U.S. servicemen and their families as well as among the Vietnamese population.
Above picture shows a four-plane defoliant run, part of Operation Ranch Hand (wikipedia)
Agent Orange was the most commonly used, and most effective, mixture of herbicides and got its name from the orange stripe painted on the 55-gallon drums in which the mixture was stored (see picture below). It was one of several “Rainbow Herbicides” used, along with Agents White, Purple, Pink, Green and Blue. U.S. planes sprayed some 11 million to 13 million gallons of Agent Orange in Vietnam between January 1965 and April 1970. According to the U.S. Department of Veterans Affairs (VA), Agent Orange contained “minute traces” of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), more commonly known as dioxin. Through studies done on laboratory animals, dioxin has been shown to be highly toxic even in minute doses; human exposure to the chemical could be associated with serious health issues such as muscular dysfunction, inflammation, birth defects, nervous system disorders and even the development of various cancers.
Photo and parts of the above paragraphs in italics are from http://www.history.com/topics/vietnam-war/agent-orange.
We should also be clear here that the US were not the only ones using Agent Orange. This interesting fact is expanded on below:
The British used Agent Orange in Malaya, but for the very British reason of cutting costs…The alternative was employing local labor three times a year to cut the vegetation. British stinginess over this matter in one respect helped to avoid the controversies provoked by the use of Agent Orange in Vietnam. The original intention was to crop spray but even this was deemed too expensive by the protectorate authorities. Eventually someone struck on the idea of simply hosing the jungle from the back of bowser trucks and this is what the British did, in limited areas and to no great effect. This happily amateur effort at chemical warfare undoubtedly saved future British governments from the litigation suffered by post-Vietnam US governments (http://www.psywarrior.com/DefoliationPsyopVietnam.html).
In fact the US were largely inspired to use chemical defoliation from the good old Brits.
Mechanical Defoliation
Mechanical defoliation makes use of heavy earth moving machinery to excavate, bulldoze or scrape vegetation out of the ground. This cannot be considered as permanent a method as using chemical agents but it has the advantage of being localised to where the machinery is being used. Crucially it does not spray poisonous herbicides from here to eternity, or cause long-lasting sickness and disease.
Deduction
So from the above two methodologies we can determine that the main use of defoliation was to:
a. Deny the enemy cover to attack from
b. Deny the enemy the ability to grow crops to feed themselves with
c. For Cordon Sanitaire purposes it also had the added use of allowing us cleared areas in which to lay mines
Rhodesian Army Defoliation Efforts
The Rhodesians used a combination of mechanical and chemical defoliation methods on Cordon Sanitaire and Non-Cordon Sanitaire operations.
So Rhodesia was apparently not squeaky clean as far as using herbicides was concerned although very little is known of their use, or the extent of such use. There is also no objective evidence that shows what if any residual effect there was on the local population and indeed our own troops. Perhaps this is an aspect that no one wants to talk about or perhaps it was just one of those activities no one knows much about. Somehow I have a feeling there is someone out there who knows a lot more about this activity.
I managed to dig up the following and once again I apologise for the lack of real meat for this post:
The Rhodesian Corps of Engineers were responsible for clearing the 25 meter wide strip of land that would eventually become the minefield with bulldozers. This mechanical defoliation methodology was used primarily to make the job of laying mines easier and to make the terrain more suitable in general for manual, dismounted operations. Laying mines in vegetated areas is both dodgy and dangerous. One can very easily become disoriented with disastrous results.
The Tsetse Fly Department (the “Fly-Men”…….see previous posts) were apparently responsible for the Rhodesian chemical warfare effort. I found this very surprising when I read about this but it appears to be quite true. Apparently they used back-pack hand-operated sprayers containing HYVAR-X. (PRODUCT INFORMATION: DuPont™ HYVAR® X herbicide is a wettable powder to be mixed in water and applied as a spray for non-selective weed and brush control in non-cropland areas and for selective weed control in certain crops. HYVAR® X is an effective general herbicide that controls many annual weeds at lower rates and perennial weeds and brush at the highest rates allowed by this label. It is particularly useful for the control of perennial grasses). You can read more about HYVAR-X at http://www.afpmb.org/sites/default/files/pubs/standardlists/labels/6840-01-408-9079_label.pdf
It seems that the Cordon Sanitaire planners were not happy with only a 25 meter defoliated corridor and gave orders to chemically remove vegetation 150 meters either side of the Cordon fences (I have to wonder how this was achieved using back-pack hand-operated sprayers). In a bid to save on costs they substituted HYVAR-X with a different chemical known as TORDON 225. This would prove to be a costly mistake as this product was ineffective and resulted in Rhodesia instituting court action against the South African manufacturers of TORDON 225.
I found only one record of chemical defoliation usage. This was apparently on the Musengezi, Mukumbura, and Nyamapanda to Ruenya minefield. Nothing else is available.
The following two photos were sent to me by Vic Thackwray, a Cordon Sanitaire veteran. They show the cleared areas between the minefield perimeter fences. In the first picture the minefield is on the left of the fence. A parallel minefield maintenance road can be see on the right of the fence. This specific photo was taken at Mukumbura.
The second photo is a great shot of Vic Thackwray standing next to the Cordon fence. Note the thick vegetation inside the mined area.
I also have some interesting input from Terry Griffin which I have added below:
The photos above were provided by Terry. They too show the type of terrain and vegetation of the Cordon at Mukumbura. I must add the terrain was not always as good as what is shown and from my own experience this was as good as it got (so don’t think we had it easy all the time).
Terry also highlighted some non-Cordon defoliation and I felt it was appropriate to include in this post. It makes very interesting reading. Terry takes up the story:
The very first minefield laying etc (again) I was OC of that – starting at Mukambura. Lt Col Horne actually came up with the team I had trained – for a look see.
Tsetse were (as per normal) responsible for erecting fences but we also had plant tp folk with bulldozers and graders clearing all so we had bare earth in and outside the minefield to work on. This was also to prevent gooks taking cover in the bush. At that stage the minefield was approx. 25m wide. In no time I realised this method was an absolute waste of time money etc, etc as we also provided armed protection for the dozer drivers etc way ahead of laying teams. To keep a definitive 25m width etc was patently stupid so I wrote a paper and suggested fences meander to create doubt as to depth of field – albeit still 3 rows – and do NOT clear vegetation as it then aided in camouflaging all. I sent you some pics of the first gook breach and just look at the nice clear earth with fences visible at exactly 25m. Boy did we have a lot to learn – and quickly. This is the only defoliation that I am aware of??
And after I prodded him for more:
Basically I was tasked with doing the defoliation on Chete Island after the gooks wacked the civvy ferry. I called up S Tp from 1 Sqn albeit I was OC Boats at the time and then we sailed plus Tsetse in the Army ferry (Ubique) from Kariba to Chete. Had strike craft as back up and positioned one at each entry to the gorge as it had been declared a frozen area for all craft during the OP. Went ashore (after anchoring on the island – invading enemy territory !! – to clear it of gooks – if any. There were none. Tsetse also provided back up (Jack Kerr plus another) with ,458 rifles in case elephants had a go at us. They did not. After positioning the guys in a defensive role we cleared the area where the gooks had fired from – onto the ferry – which still had much kit lying around from the firing point. Tsetse folk then used a defoliant called Hivar (as I recall) and by hand distributed like it was fertiliser along the entire bank facing the gorge and inland a short way. This would (as it did) clear that sector of all foliage and thereby (hopefully) deny natural cover. After the first rains it was evident all was dying off and it did clear all fairly quickly creating a rather bare scar along that section of the island. Some 10 years later it was still very visible but on my last fishing trip there + – 4 years ago all had now regrown. The gooks never did use the original firing position again.
Looking at this post I realise that although I would have liked to give the reader more on the actual defoliation in Rhodesia, what we have here is real Rhodesian Millitary Engineering history. The accounts by Terry have probably never been recorded in this format before and the photos from Vic still give me goose-bumps, bringing back a part of my history that must be told or it will be gone forever. Thanks to both of them once again for all the help and support they provide to me.
I would like to end this post with a cruel irony:
Perhaps no two people embodied the moral complexities and the agony of Agent Orange more graphically than Adm. Elmo R. Zumwalt Jr. and his son Elmo R. Zumwalt III. Admiral Zumwalt led American naval forces in Vietnam from 1968 to 1970, before he became chief of naval operations. He ordered the spraying of Agent Orange. The son was in Vietnam at about the same time as the father, commanding a Navy patrol boat. Years later, doctors found that he had lymphoma and Hodgkin’s disease. He died in 1988 at 42. His son, Elmo IV, was born with congenital disorders.
Perhaps this post has digressed a bit from the title but it does make for interesting reading I hope.
In the next post we will look at Cordon Sanitaire with electronic alarms.
