Starinov, Krushchev and the radio-controlled explosive device

In my last post I promised a little more on Ilya Starinov, the Russian explosives expert and the godfather/grandfather of sabotage explosive attacks.  In the blog post on the F-10 explosive device I recounted how Starinov himself was directly involved in planting the F-10 radio controlled device that killed German General Braun in Kharkov in 1941, and this story relates to that incident directly.

The Russian retreat from Kharkhov was carefully planned. Hundreds of “stay-behind” explosive devices were left and Starinov was directly involved. Some of the explosive devices were on timers, some of them with victim-operated switches, and a good handful of F-10 radio controlled devices, these usually with very large charges associated with them. Furthermore there were large numbers of deliberate indications  left behind that the Russians created to give the impression of yet more devices to further slow the German progress into the region – holes in the ground, disturbed earth, and hoax devices where no device was actually planted, and sometimes devices laid on top of other hidden devices.  According to Soviet sources, 30,000 anti-tank mines were laid in and around Kharkov, about 1000 victim operated devices, and 2000 timed devices.

This anecdote relates to Starinov’s role in this and I cannot be certain it is true, but it is a story worth telling anyway.  A key individual in the Soviet forces in the region was Nikita Khrushchev, who apparently worked closely with Starinov. It is clear, with our view of history, that the Russians expected a significant German EOD effort – by November 1941 the pattern of “stay-behind” devices had been set, including the use of F-10 devices hidden in likely headquarter buildings to be occupied by advancing German forces  in Odessa and Kiev in previous months.

Here’s a pic of an F-10 device being removed from the Opera House in Kiev in October 1941, by a German EOD team. The distinctive construct of the F10 receiver is clear.

-and below is a fascinating Nazi propaganda film showing towards the end the explosive charges and German EOD team’s removal and inspection of the F-10 device itself recovered from the Kiev Opera House. Quite remarkable footage.

So Starinov was instrumental in the dummy devices, and the efforts to overwhelm, fool, distract and out-think the Wehrmacht engineers.   In the run up to the German advance, Krushchev’s headquarters was in a building in Dzerzhinskiy Street on Kharkov, in a building identified by Starinov as likely to be soon used as a German headquarters. Learning the lessons from Kiev, according to this story, two F-10 devices were planted, one hidden carefully below the other in the basement.  Interestingly Krushchev did not move out from the headquarters immediately, as he felt this might give an indication to the advancing Germans that the building was prepared with F-10 devices.  So clearly Krushchev and Starinov met and there was a degree of trust between the two. But remember, the political atmosphere within Soviet forces was febrile and senior officers were frequently “purged”, accused by Beria’s secret police. In some ways Starinov had been lucky to escape, but here we see perhaps a clue giving one reason he had evaded the purges.

As the Germans entered Kharkov, they did indeed , as Starinov expected, have some success at finding and rendering safe quite a number of explosive devices. Nazi propaganda was quick to trumpet these successes and their success against the “dastardly Bolshevik devices”. This apparent success was noticed by Beria’s secret police, who saw, perhaps, that the devices were being found too easily, giving the German’s success and suggested that something had been so planned by Starinov. The Nazi propaganda from the previous month of the device being found in Kiev would perhaps have added to their suspicions. Then General Braun’s staff made an announcement that they had “easily cleared the major part of the mines”.  The secret police prepared a case against Starinov, but Krushchev got to hear of it. He advised Starinov to detonate the two devices in the Dzerzinskiy Street Headquarters now, as predicted, occupied by General Braun.

According to the source I have found the “top” F-10 explosive device planted in the cellar had, as expected, been found, made safe and the initiation mechanism presented to General Braun, showing the headquarters was made safe. The now safe initiator sat on a desk in a main room. Accordingly Starinov, warned of the expected investigation by the secret police, ordered the first device initiated – and in the main hall of the German headquarters the receiver “clicked”, to the delight of the Wehrmacht.  Five minutes later the second device, still hidden deep under the building and with a massive charge attached to it received the necessary transmission… and General Braun and many of his staff perished in the explosion. Thus , Starinov’s investigation was dropped by the secret police, and he continued his career.

I should state that other sources slightly contradict this story – saying the “top device” designed to be found was a time delay device. But perhaps the story as detailed above makes a better story – I found it in a 1963 edition of Izvestiya, and it too may well be propaganda. The best stories often are. I do note that the Izvestiya report gets the wrong date attributing it to 1942 and not November 1941.

Here’s a picture of Starinov I have found. I’m not sure when this was taken but I suspect it was some years after the war. Starinov is the older man in civilian clothes pictured with serving Russian soldiers, perhaps those he was training in the late 1960s or 1970s.

Here’s another picture of Starinov taken, I think in the late 1980s.

 

And here, as young man being introduced to Marshal Klim Voroshilov.

The efforts of the German Wehrmacht EOD/Engineer units in dealing with the significant explosive threat in places like Kiev and Kharkov in 1941 probably deserve some attention.

 

 

Railway IEDs

Strategic IED campaign on railways 1899-1902

I continue to uncover remarkable details of the Boer IED campaign against the British in South Africa.  I have detailed some of these in previous posts and railway attacks here in particular.  What I hadn’t quite realised was the scale of the campaign, which is huge, and indeed provides a template not only for the Russian partisan campaign against Nazi railways of WW2, but also in a sense the insurgent campaign in Iraq in 2003/2004.  Also see my other posts on railway attacks by clicking on the link of subjects in the right hand column – quite a few over history, including Lawrence of Arabia, the German East African campaign of WW1 and others.

The details I’m going to show you highlight that this was very much a strategic campaign targeting the British Military’s ability to move around South Africa. It also goes to demonstrate a comprehensive range of operations by the British military to respond to these IED attacks, by repairing the railway system, maintaining it, and implementing a range of C-IED security measures, not least being the “blockhouse” concept where small detachments of soldiers established patrol bases at frequent intervals along the railway.

I think it’s important to mention that the Boers were particularly effective at targeting the railway in a number of ways:

  1. By taking out key bridges. The number of bridges destroyed and then either repaired or replaced by the British Army is staggering. The Boers had significant numbers of personnel familiar with using explosives, and no lack of explosives.
  2. By blowing numerous culverts were the railway line crossed them.
  3. By damaging rails.
  4. By attacking trains and rolling stock either moving on the line or in sidings. sometimes by explosives and sometimes by simple sabotage such as removing key components, or by fire.
  5. By attacking supporting infrastructure such as watering points and water supplies. Coal supplies were set alight in depots.

There were of course plenty of Boers from the mining community with the experience to set and lay simple charges, and the IED technology evolved over time. My guess is that with no great shortage of explosives, a knowledge of what explosive placement and quality to use evolved rapidly over time – certainly the images below suggest sufficient expertise (or sufficient quantities of explosive) to blow large structures.

A variety of devices initiation methods were used:

  1. Simple burning-fuze time detonation for bridges, and track where no enemy was present.
  2. Command wire attack in an ambush situation on a train coming down the line, so the Boer’s were in sight of, but a tactical bound away from the site of the explosion.
  3. Victim operated devices placed under rails which were initiated by the train (as discussed here)

I’ve obtained a copy of the report written by the British Army Royal Engineer responsible for running and repairing the railway, where he details a lot of the repair work undertaken – from these I can derive details of the successful IED attacks over quite a period. To be clear, this account doesn’t focus on the IED attacks themselves in particular but the running of the railway as a system, and with the repair process as a part of that but we can draw useful analysis of the IED campaign against the railways from it.  So here’s some summaries and exemplar detail. I should mention that the name of this Engineer officer is Édouard Percy Cranvill Girouard. (!) Or rather Lieutenant Colonel EPV Girouard KCMG, DSO, RE, to give him his full title.

  • Largely because of the distances involved, the British Army, relied extensively on the railway system for strategic movement and routine logistics. There were 4600 miles of track in the system in a series of interconnected networks.
  • The British Military took over the operation of the railways completely in 1899, retaining local staff were possible. There were, of course, challenges were railway works were Boer sympathisers. This was a managerial challenge. A huge “lesson-learned” for the Royal Engineers was the need to develop competency in complex railway systems management.
  • Repairs to the railways were often carried out under fire, or at least in the presence of the enemy
  • Water is a crucial component of running a steam railway and the Boers realised this and disrupted water supplies too. The British on occasions resorted to running “water trains” to supply water for other trains. At one point the entire water supply for the railways around Bloemfontein was cut by the Boers from April 1900.
  • The number of bridges damaged by explosions is significant. here’s a summary of bridges reconstructed following an attack – divided into two lists depending on whether they were built originally in imperial dimensions or metric:

So that’s a total of 278 railway bridges requiring reconstruction following attack by the Boers with explosives.  After these were repaired, military posts were set up to guard every span over 30ft – leaving only smaller bridges,  culverts and regular track as the target for Boer IEDs. As you can see, that’s quite a manpower bill in itself in terms of a counter-IED strategy. Later, blockhouses were set up providing a blockhouse protected against rifle fire and surrounded by barbed wire every 2000 yards along the railway lines, each manned by a small number of troops (about ten each) – quite an investment in resources, but crucial to keep logistics functioning.

Here’s just a few of the bridges damaged by Boer IEDs, and subsequently repaired:

The Modder River Bridge:

The Vaal River Bridge:

The Colenso Bridge over the Thukela river with two parallel Royal Engineer replacement bridges being built (often under enemy fire)

The Orange River bridge, with replacement bridge alongside

The Norvalspont Bridge: This bridge was repaired in 14 days, or at least a secondary Laine installed (see the rails at the base)..

The Bridge at Fourteen Streams

I could post many more pictures of IED damaged bridges, but I hope I’ve got my point over that this was a strategic IED campaign, and required a strategic repose from he British Army.  The files I have obtained detail the amazingly short periods of time it took the Sappers to temporarily rebuild many of these significant bridges.  Here’s an excerpt of just one page of dozens more, note the speed of the engineer operation:

 

As well as these major bridges, many smaller bridges were also blown along with probably hundreds of culverts. Lines and points were damaged either by pulling them up or damaging them too with explosives. To give an idea of intensity of IED attacks, this is an excerpt listing just one month of attacks on just one part of the network:

With the adoption of the pressure sensitive IEDs used by the Boers, train engines were armoured to protect the crew and then trucks were pushed ahead of the engine on every “first train of the day” as sacrificial elements to initiate any IEDs ahead of the train.

One particular counter-measure against IEDs that I have discovered fascinates me and returns to the theme of Remotely Operated Vehicles. An “inventor” in England suggested deploying a carriage powered by a heavy electric motor some distance ahead of the engine, to which it was connected by long electric leads. So a wire controlled ROV on rails, in effect. This was trialed in theatre (like sometimes such ideas still are!) but found to be impractical, for the following reasons:

  • It was sacrificial and was expensive in itself to be replaced.
  • It was difficult to control, keeping the wires sufficiently taut so the train didn’t run over them or have the leads pulled from the controller.
  • The wires caught in any trackside object (including trees, blockhouses, telegraph poles etc.
  • It couldn’t cope with curves without causing more problems.
  • The Boers had already started using electrically initiated command wire IEDs anyway, so could ignore the ROV.

Nonetheless this demonstrates, that even in 1901 that innovative ideas were being sought to deal with IED threats. And .. it’s another early ROV.

With regards to other innovations, this next one is a bit peculiar too. Over time the “blockhouses” placed 200 yards apart were added to so there was even less distance between them. The gaps between were under observation (in some cases at night with the use of searchlights) to prevent insurgents placing IEDs on the rails and patrolled frequently. Do this was a strategic effort to observe all of the communication routes used by there British.  Another innovative concept implemented, I kid you not, was the use of specialised bicycles.  These “war cycles” consisted, at first, of two bicycles, fastened on a common frame with wheels adapted so that the cycles ran on opposite rails.  two sliders would pedal between blockhouses providing route coverage. The adapted wheels enabled the cyclists to use both hands to fire weapons , and progress was relatively stealthy.  Later, a larger “8 man” war-cycle was built proving more firepower. a lot of these machines were made in Cape Town and used by the Royal Australian Cycle Corps.

Other innovative responses to attacks included this fabulous add-on armour to a train (admittedly not necessary against IEDs). British soldiers, almost inevitably, came up with the nickname:

The conflict also prompted innovative use of other battlefield technologies such as armoured vehicles, and use (by both sides) of wireless radio communications – perhaps a first in a conflict.

To summarise, I think we can see in this conflict:

  • A strategic and extensive IED campaign by the Boers as a part of an insurgency campaign. The patterns of similar strategies with later campaigns up to the modern day are clear, and in particular the Russian inspired partisan campaign against the Nazi rail system in WW2.
  • A coherent response of sorts from the British Army, in terms of resourcing appropriate management control of the crucial national rail network
  • A component of that response included resourcing repair teams and military engineering capabilities of sufficient size and flexibility to respond to the intensity of IED attacks
  • A manpower intensive (but ultimately successful) security operation to protect the exposed logistic capability
  • A search for innovative counter IED methodologies and ideas, some of them implemented successfully but time wasted on others. Sounds familiar.

 

 

19th Century

IEDs in the Boer War

I’m currently digging in to instances of the British Army using IEDs in various campaigns. There’s a couple of interesting stories from the Siege of Mafeking (1899-1900). The British were surrounded at Mafeking and held out for quite a period against the Boers.   They were short of supplies, but led by Baden-Powell used all sorts of ingenious methods, including improvised explosive devices (and hoax explosive devices) to keep the Boers at bay. Certainly the Boers were intimidated by the threat of these improvised landmines (often placed in likely artillery positions). The Boers too made extensive use of IEDs at this time.

Other munitions were developed at a workshop in the railway yard.  There were a large number of improvised grenades made , using dynamite, a tin can and a burning fuze.   Other IEDs used Boer artillery shells that had failed to function, and indeed on more than one occasion using recovered Boer IEDs that and been rendered safe. Here’s the description of one such, by Baden-Powell the Garrison-Commander, talking about a forward Boer position that they abandoned:

Their somewhat noisy retirement made me suspicious, and two scouts were sent on to see if all was clear. They found some wires, quite newly laid, and a mine of nitro-glycerine, so something equally soothing, awaiting our entrance into the work. The wires were therefore cut and wound in for future use against the layers. And while we sang ‘God save the Queen,’ the Boers were probably touching the button at the other end of the wire with considerable impatience at their failure of their fireworks.

Seasoned “standingwellback” readers will recall that I have written before  about Boer railway line IEDs here.

The defenders too used electrically initiated IEDs – one here was awarded a “Mention in Dispatches” thus:

Koffyfontein Defence Force-Corporal H J Jellard (promoted Sergeant); on October 11, for exposing himself to heavy fire at 60 yards’ range when getting on to a debris heap to connect a wire from a battery to a mine, and also for holding an advanced position with assistance of one native

One particularly effective method of delivering improvised grenades to the target was drawn by Baden-Powell himself – no mean artist:

Sgt Page (other reports name him as Sgt Moffatt) used a fishing rod and line with the grenade attached to the end of the casting line. Apparently he could deliver the improvised grenade a distance of 100 yards with some precision.  Baden-Powell suggest that the fishing rod technique replaced a mechanical spring device which was less effective (a technique seen in recent years in Syria). The Baden-Powell sketch was then used as a basis for this image below, which also shows on the right an ingenious “dummy” to draw fire.

In one of those odd parallels, you may recall that I wrote about an improvised artillery piece used during the Boxer rebellion (1899) here, that had been dug up in a garden. Well there was also an improvised artillery piece art Mafeking also used in 1899. It too was dug up in a garden It is described here by Baden-Powell himself:

The third gun was one which Mr. Rowlands dug up from his garden: an old muzzle-loading ship’s gun with a history.  We had it cleaned up, sighted, and mounted on a carriage, and it did right good work. Owing to its ancient Naval connection the gun was named ‘Lord Nelson.’   It was made in 1770 and weighted 8 cwt. 2 qrs. 10 lbs. These figures 8.2.10 were inscribed upon it and led some people to suppose it was made on February 8, 1810. It also had the initials ‘B. P.’ Upon it, which might have led such people further to suppose that it belonged to me in former times. It didn’t really; those initials stood for Bailey, Pegg & Co., the makers, of Brierley Foundry, Staffordshire. The absence of the Royal Cypher showed that it had not been a Royal Navy gun but belonged to a privateer. According to local tradition two Germans brought it to Linchwe, a neighbouring chief, some forty years ago, and he sold it to the Baralongs for twenty-two oxen, to aid them in their defence against Boer freebooters.  It fired a 10-lb. shot, and carried 2,000 yards, though not with great accuracy. We found its sister-gun in Rustenburg, where in 1881 it had been used by the Boers to shell the British defence works. And a third gun of the same family was found by General Burn-Murdoch near Vryheid; while a fourth stands, I believe, at Brierley Hill, having been presented to the town by the makers.

How extraordinary that in two sieges in separate parts of the world, at the same time, they both used ancient cannon dug up from a garden.

Other artillery pieces were entirely improvised, here described by Baden-Powell again:

Our great gun was our home-made one, ‘The Wolf’ (my nickname from Matabeleland). This was made from a steampipe round which were lapped iron rods which were welded and turned till a good strong barrel was made. The breech and trunnions were bronze castings. The whole was built up by the railway workmen under Mr. Coghlan, the energetic and ingenious foreman, and under the general supervision of Major Panzera. The blast furnace for making the castings alone was a triumph of ingenuity made out of a water-tank lined with firebricks — the blast being introduced through a vacuum brake tube.

The “Wolf” is now held by the Royal Artillery Museum, due to open later this year.

Baden-Powell also mentions this IED attack – reminiscent of more recent IED attacks I have also blogged about here and here

The Boers sent a trolley loaded with dynamite rolling down the railway into Mafeking, but it luckily exploded before reaching us — about a mile outside.

 

Rather oddly Baden-Powell doesn’t mention that the British themselves used the same tactic. On 13th October, a British locomotive pushed TWO carriages full of dynamite out of Mafeking on the railway until they saw Boer’s in the distance. Fuzes were lit and the carriages rolled towards the Boer position – but were detonated by rifle fire from there Boers.
 It’s clear that the demands of the remote and isolated town of Mafeking demanded innovation and improvisation from the occupants – and many of the same pressures were prevalent on the Boer side. I’m struck by the leadership shown in reading Baden-Powell’s notes on his command during the siege. Quite remarkable. It also further highlights the prevalence of improvised munitions in history, and shows the same patterns, driven by tactics and tactical design as we still see today.
Update:   Here’s a pic of the Wolf howitzer, made in the railway workshops in Mafeking, and some improvised munitions for it.  Sometimes Pounder shells fired at the British by the Boers, but which failed to function were recovered, somehow re-fuzed and fired back.
And here’s a sketch of the “Nelson” in action:
16th Century

Execution by Gunpowder

A peculiar story. In Utrecht in the Netherlands in 1562, Hendrick Eemkens was sentenced to death by a court for the crime of being an Anabaptist, a form of radical Protestantism at the time.  He was ordered to be “executed by gunpowder” in the city square in front of a crowd of people.  To achieve this he was tied to a stake and a charge of gunpowder draped around his upper body and neck. I’m not sure of the size of this charge. Some reports suggest he was throttled first.  A fire was lit close by and the executioner, using a long pitchfork, lifted a bale of burning material into contact with the explosive charge. I’ve found two images, admittedly from over a century later, showing the execution.

The second is a little more explicit

The clergy behind the victim doesn’t look like he’s standing well enough back.  One report observed that the man’s hair was not singed in the explosion.

Radio Controlled IED

German WW2 use of ROVs to deliver explosives

In recent years various terrorist groups and others have used land, sea or air ROVs to deliver explosive payloads to targets.  As usual, people view these things as new and innovative threats. But as readers of this blog site will know,  that usually isn’t the case and I have more details here of some interesting early use of such devices from WW2, although they go much further back.  Some of these may be classed as “improvised” but others are clearly formally developed systems – but let’s not get hung up on definitions, because the concept is what is interesting   There are several aspects to this – one is the technology that is used, and another is the tactical employment. Many of the implementations of this concept were unsuccessful but the reasons for this are also interesting and indeed are being repeated in modern terrorist use of ROV technology.  I won’t go into that aspect in too much detail for obvious reasons.   So here goes with a few interesting  German “land based” example ROVs from WW2.

I’ve written before about the WW2 German “Goliath” remote controlled mine, a small tracked vehicle not too different in scale from modern EOD ROVs.   Following the fall of France in WW2, the Germans captured  a prototype French ROVs used for explosive charge delivery which seemed to inspire the development of the Goliath. This vehicle had been “hidden” in the River Seine, but the Germans got to hear of it and salvaged it for technical exploitation and reverse engineering. (Readers may recall a similar reverse engineering operation from a “purchased” French speed boat just before WW1, that I discussed in an earlier post).

 

Captured German Goliath ROVs after D-Day

While there has been some attention on the Goliath tracked vehicle, used to deliver demolition charges to targets, perhaps just as significant for us looking at history was the German Borgward B remote tracked vehicle. A contract was let by the Wehrmacht to the Carl Borgward engineering company in Bremen for 50 tracked vehicles in 1939. It’s not quite clear if the Borgward B was developed originally to deliver demolition charges or for other purposes such as towing mine clearance tools or as an ammunition carriers.  One suggestion is that during the German invasion of France, German engineers found an operational need and had been converting, in an improvised way, standard German tanks to operate remotely for certain tasks. The theory goes that as a result of after-action reports from this campaign the Borgward B was converted to fulfil this role. But it’s war and it’s a little confusing as to which came first, the chicken or the egg.    In any event,  Blaupunkt, the radio manufacturer developed a radio controlled system for the vehicle. These vehicles and their sub-systems were gradually improved in following years resulting in several “versions” as both their use and requirements changed.  A variety of vehicles were used as “control” vehicles as the war progressed. The radio control unit was very “modern” in appearance, using a joystick control and shared many of the features of the Linsen boats control systems.  The key features of the Borgward B was firstly that it could deliver a large charge, (typically 45o – 550kg), and secondly it could drop off the charge and retreat, thus in principle being a re-usable vehicle, unlike the smaller and disposable Goliath.

Here’s a pic of the Borgward B. The driver would drive the vehicle “normally” until it was a “tactical bound” away from the target, then he would get out and the vehicle would then be controlled by radio remotely. It looks like a fun  drive, (unless you are told to drive it to the Eastern Front).

 

The Borgward B wasn’t a huge success. it was unreliable and quite vulnerable to enemy fire.  Some reports suggest that some versions were equipped with smoke units to lay smoke screens or just to hide its own approach, but I’m not sure how it would then be controlled if surrounded by its own smoke screen. Perhaps this version was simply used to lay smoke screen and move laterally across the battlefield.  I have found a report that a single Borgward B was fitted with a TV camera as an observation vehicle during the fall of Berlin, perhaps a prototype but in the main the later use of these vehicles, in theory was to deliver and drop demolition charges.  The explosive charge, when dropped, had a timer initiation system that after a short period caused the charge to detonate.   The charge was released with the help of gravity after explosive retaining bolts were fired by the operator. I’m cautious about this and think it could have been a lever actuator.   It appears that there was an adjustable safety mechanism that armed the charge only after a certain distance (not time) had been covered, so for instance an operator would set the safety distance to 100m as he exited the vehicle, and the charge would only become “armed” after the vehicle had covered that distance. That’s logical, but I’m not sure how it was achieved.  These vehicles were less suited, of course, to defensive operations than offensive, where their utilisation against defended structures was optimised. I’m led to believe that over a thousand Borgward Bs were produced (compared to many thousand Goliath vehicles).

Here’s a great pic of the explosive charge after being “dropped off” by the vehicle. You can see it slides off the front plate where it is held in a “shoe”.

I think it’s worth thinking about the relative strengths and weaknesses of the Borgward B and the Goliath.  The Borgward B could be moved into its tactical launch position by one man, but the Goliath needed a small team of men.  Perhaps that’s why the Goliath was used in defensive positions like the beaches of Normandy, where it was prepositioned in shrapnel proof hides, (but it wasn’t particularly effective). The Borgward B was larger and therefore more vulnerable, but delivered a much bigger charge than the Goliath more suitable to taking on defensive positions. The Borgward B was more expensive but in theory was reusable. In the main the Borgward B was radio controlled and this offered some flexibility but also posed some reliability problems with the technology of the day. The cable system principally used by the Goliath was more reliable but vulnerable to shrapnel damage.

There was an attempt at a “middle ground” the NSU “Springer” ROV developed in 1943/1944. This was smaller than the Borgward B, bigger than the Goliath, but was driven into launch position by a driver. About 50 were made, I think. Here’s a picture showing its scale and size. They seem to have limited operational use. I don’t have a handle on their control system.

 

I think it’s fascinating that the Germans also used vehicles captured  from the British and French and convert to ROVs. It seems that the German engineers saw potential in particular from the British Bren Gun carrier and the Belgian “utility tractor” (a British built tracked vehicle made by Vickers, who also made a proportion of the British Bren carriers).

Here’s a pic of both in “normal use”

A Belgian Vickers Utility tractor

Bren Carrier

A number of both these vehicles were converted to be cable-controlled demolition vehicles, each with a 1.2 km cable.  That’s quite a distance, and one imagines that control of vehicle at such range was tricky, based on distant observation.  A total of 60 were sent to the Crimea in 1941.  The German Crimean campaign of 1941 is interesting because I think it was used as a testing ground for range of innovative German technologies.  I’m currently exploring the use of an advanced prototype German fuel air explosive weapon in this campaign, to clear bunkers and defence structures, and it appears that these converted Belgian and British ROVs were used against the same targets to deliver relatively large explosive charges. I have also seen reports of Borgward B vehicles used in the Crimea at this time.  It appears that the majority of the 60 vehicles were deployed with mixed results – some destroyed by mines before they reached the targets, some destroyed by enemy fire, some failed and some functioned as intended destroying Russian defensive positions.  I can find no specifics over the amount of explosives carried by either vehicle, nor any specifics on the control mechanisms fitted.   It appears that the ROVs were “controlled” from a “mother” command tank.  The Germans complained that there were no spare parts for the captured ROVs and recommended development of indigenous vehicles accordingly.  Other feedback included the suggestion that they would be better employed in flatter, desert conditions, such as North Africa, rather than the complex urban defence environments of Sebastopol, and indeed at least one Bren carrier, captured at El Alamein was so converted.   While this effort to convert enemy tracked vehicles to wire guided demolition use wasn’t really repeated , it’s clear it had some success and more importantly allowed the Germans to develop tactics and concepts of operation. . I think too, given the large amounts of “enemy” vehicles abandoned in Europe at Dunkirk and elsewhere, it made economic sense to utilise them, and the Germans had no qualms about recovering, and using, where possible, quite a range of enemy equipment.

This picture is, it is claimed, a captured Bren carrier (complete with German Cross) fitted with explosives being deployed on the Eastern front. The vehicle in the distance is Borgward B, I think, so it seems very likely.

I think it’s fair to say that the Goliath and the Borgward B ROVs were less effective than the Germans had hoped in normal operations on the Eastern and Western fronts. But it’s worth looking more closely at their deployment in the tight urban environments of cities. There are notable reports of Goliaths being deployed into the Warsaw Ghetto in responding to the Warsaw uprising in 1943.  If ever there was a historic precedent to the urban destruction seen in modern day Syria, the destruction of the ghetto by the German in 1943 is it.    Goliath were used to target buildings, and of course with only small arms the defenders had little defence against these ROVs, unlike formal military units.  I also see parallels with modern anti-tank missiles being used against defensive positions in Syria, of which we are seeing many. Yes these aren’t as fast as those missiles but the targets and tactics are quite similar.

Here’s the remains of a burnt out Borgward B vehicle, I think destroyed by fire after it had dropped off its charge in Kilińskiego Street in Warsaw in August 1944. The explosion reportedly killed 200 residents. The story of this attack is dramatic and a desperately sad tragedy. Essentially the vehicle had been captured by Polish troops as the Germans attempted to deploy it towards a road block and was being paraded around Warsaw by cheering locals. Someone pulled a lever which caused the deployable explosive charge to slide off, and as we know there was a timer started by this activation which the crowds did not understand.  The charge detonated shortly after.  There is more detail here if you are interested. It is possible of course that this was a “Trojan horse” attack, and a number of sources claim this but I suspect that it was just accidental.

Here’s some pics of the Goliath systems being deployed in Warsaw.

This is the effect of a Goliath on a building in Warsaw

I think the German forces of WW2 had, in their ROVs, some interesting tools for offensive operations, and for the built up environments of  Warsaw and heavily prepared defensive environments off Sebastopol they were of some use.  But for German defensive operations, they were less suited. Fundamental unreliability was a major issue, it seems, with all the systems they used, and that’s both in terms of motive power and in terms of the control systems. Modern technology perhaps allows for more reliance on the systems used by terrorists and others. In a battle there is perhaps more of an issue of unit cost – whereas modern ROVs are cheaper, and not being deployed, in general, in battle conditions are doubly attractive. Modern ROVs have more precise controls including reliable and usable video components that makes control easier and more attractive. More accurate control also leads to the potential to reduce charge size and so allow the vehicle to be smaller. I think this aspect of modern ROV weapons is not yet widely understood.  Improved batteries for electric vehicles also increases range.  The issue of logistic support is somewhat useful in understanding use of ROVs for delivering explosives and again modern terrorist use changes the impact of that logistic support and is maybe less crucial in terms of systems.  What is inescapable now and in the past is that ROVs offer an aggressor a safe way of delivering explosives, with the size of the explosive charge required having, of course, an impact on the vehicles that might be suitable.  The key difference today is that technology has improved reliability of control systems, and also that technology is broadly available.  However it is susceptible to technical counter-measures.  In particular radio control systems are now consumer items and not limited to government enterprises.  There are also some other parallels in terms of utilisation of captured weapons systems – and here I’m thinking of the way some Syrian jihadists have adapted captured armoured vehicles for suicide VBIEDS.

I recommend thinking in terms of tactical design – the systems outlined above all approached the target to a “control” point. From there the mode of control switches – and remote control takes over.  It’s worth, as with any attack system, particularly terrorist attack using radio or other command systems, having a hard think about what defines that “control point”.  What are the characteristics of that change over point that are needed, are chosen and utilised? Understanding those will help you develop some counter-measures. Modern day control points are perhaps less clearly defined than these WW2 examples, but the principle remains. Another thought that comes to mind is the importance of Technical Intelligence to the EOD operator. Put yourself on the shoes of an EOD tech 75 years ago – what would you want to know about the command and initiation system before you dealt with such an object? It may have no relevance today but as a “process” it’s useful to think through how you, a modern EOD operator, would deal with such things in a variety of situations – it’ll get your brain thinking, and that’s the best use for a brain.

Most of you will be aware of the command driven vehicles used by modern terrorist groups – various Jihadi ones, ETA, FARC and the IRA have all use such systems and others too are in the back pages of this blog site. But most importantly don’t be then thinking remotely driven vehicles delivering explosives are anything new – they are more than a century old and there are lessons to be learned still. From a historical perspective I’m intrigued by the German campaign in Crimea and the manner in which they used innovative weapons systems there – I’ll be digging further as it’s not a part of WW2 that I’m all that familiar with and instinct is telling there’s some interesting history. I have one wild reference to an ROV being used underground there which I’m trying to track down, and of course Russian defence of Sebastopol in the century before has been a subject of previous blogs. It’s strange how the patterns of explosive use over the centuries return to the same places. Sebastopol, Antwerp, London…
