The Bath School Bombing – 1927

I’ve been doing this blog for some time, and vacuuming up data on historical bombing incidents for even longer. For some reason I thought I had done a piece on the Bath School Bombing some years ago – but turns out I hadn’t.

The tragedy of the Bath School Bombing is still with us today – so called “lone-wolf” terrorists with a grievance against society are still with us and that strange focus on schools still perplexes us all. The attack has some technical aspects that are interesting – the bomber emplacing a concealed large device over many weeks, the classic “return to the scene” and the use of a suicide car bomb – an early one.

Here’s the story. In 1927 Andrew Kehoe was a 55 year old single man living in the town of Bath, not far from Lansing in Michigan, USA. His mother had died when he was a child. His step-mother died in a strange accident with a stove and there are allegations that Kehoe or his father may have tampered with that stove.  So, he had a troubled childhood.   He had in earlier years killed a neighbour’s dog and also a horse that he owned, out of frustration with it. So – an angry man. He later qualified as an electrician which is probably pertinent.

In 1926 Kehoe lost a local election, and this appears to have been the cause of his subsequent acts. He started stockpiling explosives at that time, and also, it seems he undertook various actions to make his foreclosed farm less valuable to its eventual owners – he cut all the wire fencing, killed the trees and killed his grapevines. His wife, Nellie, suffered from tuberculosis and this further strained his finances. At the time of the attack she was chronically ill.

It seems Kehoe’s plan was to punish the community that rejected him – and that the school, (which he objected to paying taxes to support) was as good a representative of the community as he could find. Indeed he was employed by the school as a temporary electrician at one time, so knew the layout and access to the school buildings. Kehoe bought explosives from farm suppliers in small batches over many months and after the incident, police came to the conclusion that more dynamite was stolen by him from a bridge construction team some time earlier.

On May 16, his wife Nellie was discharged from hospital and some time later was murdered by Kehoe. He set a number of incendiary devices in the home and its outbuildings. These were initiated at 0845 on 18 May.   At about the same time, a timed explosive device detonated underneath the North wing of the school where the device had been hidden in the basement. The device was timed with an adapted alarm clock. 38 people were killed in the explosion – mostly children. Lessons had started 15 minutes earlier.

At about 0915, Kehoe arrived at the bomb site in his Ford truck. He summoned over the police chief, Superintendent Emory Huyck.  There was a brief struggle over a rifle and then the truck itself exploded, killing Kehoe, the Police Chief, a local man, and a child who had survived the first explosion. Another man died later from injuries caused. It appears that additional shrapnel had been piled on the back seat on top of a charge of dynamite. I think there is little doubt that this was in effect a suicide VBIED. Investigation at his home found the body of his wife and also two dead, hobbled horses , feet tied with wire, in a burnt-down stable.

During the follow up to rescue injured children another 500 pounds of explosive was found in the basement under the South wing of the school. It had failed to detonate, but was also attached to a timer set to switch at 0845.  Here’s photo of the recovered explosives.

After the events investigators found this sign attached to the Kehoe property gate, presumably attached there by Kehoe himself.

This sad tale suggests that lone bombers are not solely modern phenomena. Easy access to explosives enables such acts, and the technology is “easy”.  The strained mental health of potentially violent people remain issues today.

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.

 

 

VBIED

Two-Ton Boer Train VBIED 1902

I wrote recently about  trains or carriages on railways full of explosives sent towards each other by both sides (the British and the Boers) at the Siege of Mafeking in South Africa in 1899/1901, and I’ve just uncovered another from the following year.

In 1902 a small British Garrison at Okiep in the Northern Cape region was surrounded by Boer forces. On 1 May 1902, the Boer commandos launched a VBIED attack on Okiep, using the commandeered locomotive “Pioneer” of Concordia’s Namaqua United Copper Company to propel a an IED in the form of a wagon-load of dynamite into the besieged town.

Two tons of dynamite were loaded onto carriages behind the “Pioneer”. The train driver was Field Cornet Jan van Brummelen, and he was to be accompanied by two “Irish explosive experts”.  The men were to leap off the train before it arrived at the target. I’m pretty certain the device would be initiated by a timed burning fuze.

What followed is a little uncertain, as is often the case. Some reports suggest the protective defences at Okiep consisted of a barbed wire fence, which was erected across the railway line at Braakpits Junction, just north of the town. The points at the junction were rigged in some way to the fence, with the result that when the dynamite laden wagon breached the fence, it derailed at the points and spilled its load of dynamite on the ground, where it “burned out harmlessly without exploding”.  Other reports suggest that the local station master, Albert Gyngell, heroically turned the points to direct the train away from the town centre, and it subsequently derailed.  Here’s a pic of the train after the dynamite had burned away:

So, yet another in the long list of vehicle-borne IEDs that occurred (or in this case attempted) in history. The “remote delivery” mechanism for this vehicle-borne IED failed but the intent was clear.

I am uncovering many more IED attacks in this conflict than I had realised (thousands!) and will be blogging more about the comprehensive attacks the Boers made on the strategically crucial railways over a couple of years. There’s a fascinating story to be told – and it also involves the British Royal Engineers undertaken some remarkable bridging and other “counter-terrorist” or “counter-insurgent” responses to this comprehensive IED campaign against the key transport system in Such Africa. In some ways its presages there Russian sabotage campaign against the Nazi railway system in WW2 and the Iraqi insurgent campaign against US and UK road traffic in the early part of this century. Same techniques…

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:
17th Century

An explosive device in Whitehall

Some more detail of an early IED attack attempt that I had heard about  but which I didn’t have much detail of until now.  I mentioned in my post a couple of years ago here (Bomb Alleys) about an assassination attempt on Oliver Cromwell, with a device designed to burn down Whitehall Palace and I’ve found a few more details in the transcripts of the trial in ” Cobbett’s Complete Collection of State Trials and Proceedings etc Volume 5, pages 842-872″.    It seems this was a successful EOD operation as part of a complex counter-terrorism operation. What a curious world counter-terrorism was in those days – as it remains today.

Cromwell – the target of the assassination attempt

The counter-terrorism operation was run by Oliver Cromwell’s spymaster, John Thurloe.  The protagonist in this was one Miles Sindercombe, whose pseudonym was “Mr Fish”. Sindercombe appears to have been funded by a rebel puritan officer, Colonel Sexby, from the Netherlands.  After four plans to ambush Cromwell had failed, Sindercombe decided to burn down Whitehall Palace, where Cromwell was living, in the hope that it might kill him.  The device he used was constructed “by a man sent from overseas”.

The device was in a wicker basket, and contained, a gunpowder charge, and “tar, pitch and tow” and “brimstone” to add an incendiary component. It had two “slow match” burning fuses in parallel with an expected delay of about 6 hours. That’s quite a delay for a burning fuse. The device was left in a chapel in the Palace (now the site of the UK Ministry of Defence, and buildings in that area), which Sindercombe had reconnoitered by attending a service earlier. On 8th January 1657, Sindercombe and his accomplices gained entry via a back door into the chapel, and hid the device under a seat. They lit the fuze and left the premises. However Sindercombe’s cell had been penetrated by government agents working for Thurloe and the authorities were alerted.  The Palace Guard “found” the device and the Officer of the Guard rendered it safe by removing the burning fuzes.

Sindercombe was injured resisting arrest the following morning, and refused to co-operate. However all his co-conspirators did cooperate, gave testimony and Sindercombe was found guilty and sentenced to death a month later. He escaped the gallows by committing suicide by poisoning but suspicion remains he was killed to prevent a riotous public assembly at the execution. There are details of a rather bizarre post-mortem conducted some time after he had been buried beneath the gallows with a stake through his heart.

The details of his earlier assassination attempts on Cromwell are also intriguing. In one he hid an arquebus and pistols “in a viol case” (very 1920s…). In another, a purpose built firearm was to be used, described as a “strange device” that fires 12 bullets and a slug at the same time. Peculiar.

It’s surprising to me that this assassination attempt of the de facto head of state is little known about. Whitehall Palace – a mish-mash or architecture and complex passages , built mainly from wood did eventually burn down fifty years later. During the attempt to put out that fire in 1698 gunpowder charges were used to try to create firebreaks.

Here’s a useful pic of the Palace in 1680 – I’ve highlighted the chapel. It does indeed look like a warren of buildings. Those of you familiar with the area in modern day can orientate yourself with the Banqueting House and Horseguards
