This blog has evolved into a review of historical and modern explosive devices, and responses to them. Links are drawn between historical activity and similar activity in the world today. Mostly I focus on what are now called IEDs but I have a loose personal definition of that and wilingly stray into discussions of more traditional munitions, the science and technology behind them, tactical employment and EOD responses. Sometimes it's just about interesting people in one form or another. Comment is welcome and encouraged but I do monitor it and reserve the right to delete inappropriate stuff. Guest posts are always welcome. Avoid any stuff that makes the enemy's job easier for them.

A note on moral perspectives. Throughout this blog there are descriptions of all sorts of people using IEDs, explosives, or suffering the consequences. Some of the people using IEDs are thought of as heroes by some and terrorists by others. One person's good guy fighting for a cause is another person's evil demon.  It's complicated, and history adds another series of filters too. All of us too live in a narrative made up around however we were brought up, what we were taught and what we learned along the way, rightly or wrongly. So if you sense moral ambivalence, one way or the other, well, I'm guilty and I'm not perfect.  By and large though, I have unapologetic sympathy for those dealing with the devices, whether they be soldiers, cops, or whatever, even those who are part of Nazi or other nasty regimes. That's the cool thing about EOD techs - we don't really care who the enemy is.

Investigating Zeppelin Bombs - WW1 Tech Int

A while back I posted a long piece, here, about a number of German airdropped bombs including a peculiar incendiary dropped from Zeppelins.  Here's a picture I just found of two officers inspecting the remains of such a device - Tech Int from WW1.  I think the "well-known naval airman" on the right might be Lt Rex Warnford, awarded the Victoria Cross for shooting down a Zeppelin.

D'Oyly-Hughes's IED

As is often the case my previous post on the IED attack from the US Navy Submarine, USS Barb in 1945, sent me down an investigative alley.  Here's details a similar attack, this time launched from a British submarine, against an Ottoman train line in the Dardanelles in 1915 in WW1.

The leading character here is Lt Guy D'Oyly-Hughes, the first officer on the Royal Navy submarine, the E11.  This submarine had an incredible aggressive series of operations against the Turks at the time of the Dardanelles campaign in 1915, sinking over 80 vessels on three operational tours.   In August 1915, they hatched a plan to blow up a key railway line with explosives after attacks with its deck gun on the railway line at Ismid had proved ineffective. This was the railway line that ran between Istanbul and Baghdad, so was very much a key transport route.

Lt D'Oyly-Hughes constructed a small raft containing two barrels into which he packed the components for his device. The main charge was gun-cotton, (frequently used for such purposes in WW1 and earlier) initiated by burning fuze to a detonator.  The burning fuze was itself initiated by a system we are not that familiar with these days - using a special "pistol" which fired a flash cartridge. The pistol was used by Navy and Engineer units because the system was much less likely to be damaged by water. Here's a picture I have found of such a pistol, although this one may be from the late 1800s.

I have also, surprisingly, found two photographs of Lt D'Oyly-Hughes with his explosive raft, one on the transom of the submarine before the operation and the second as he entered the water off the coast of Turkey. 

Before launchIn the waterThe raft contained 16lbs of guncotton. Lt D'Oyly-Hughes, swimming, pushed the raft towards the shore. Here's what happened next from the official history of British Naval operations:

 

Finding the cliffs were unscalable at the point where he landed, he had to relaunch the raft and swim further along the coast till he reached a less precipitous place. Armed with a revolver and a bayonet, and carrying an electric torch and a whistle for signalling purposes, he laboriously dragged his heavy charge up the cliffs, and in half an hour reached the railway. Finding it unwatched, he followed alongside the track towards the viaduct, but he had only gone about a quarter of a mile when he heard voices ahead, and soon was aware of three men sitting beside the line in loud conversation. It was impossible to proceed further undetected, and after watching them for some time, in hopes of seeing them move away, he decided to leave his heavy charge of gun-cotton where he was and make a detour inland to examine possibilities at the viaduct. Beyond stumbling into a farmyard and waking the noisy poultry, he managed to get sight of the viaduct without adventure, but only to find that he was beaten again. A number of men with a stationary engine at work were moving actively about, and the only course was to retrace his steps and to look for a vulnerable place up the line where he could explode his charge effectively. A suitable spot where the track was carried across a small hollow was soon found too soon, in fact, for it was no more than 150 yards from where the three men were still talking. But the place was too good to leave alone, and deciding to take the risk, he laid the charge, and then, muffling the fuse pistol as well he could, he fired it, and made off. For all his care the men heard the crack, started to their feet and gave chase. To return by the way he came was now impossible. His only chance was to run down the line as fast as he could. From time to time pistol shots were exchanged. They had no effect on either side, and after about a mile's chase he had outdistanced his pursuers and was close to the shore. Plunging into the sea, he swam out, and as he did so the blast of the explosion was heard, and debris began to fall about him, to tell of the damage he had done.
Yet his adventure was far from over. The cove where the submarine was lying hidden was three-quarters of a mile to the eastward, and, when about 500 yards out he ventured to signal with a blast on his whistle, not a sound reached him. By this time day was breaking and his peril was great. Exhausted with his long swim in his clothes, he had to get back to shore for a rest. After hiding a while amongst the rocks he started swimming again towards the cove, till at last an answer came to his whistle. Even so the end was not yet. At the same moment rifle shots rang out from the cliffs. They were directed on the submarine, which was now going astern out of the cove. In the morning mist the weary swimmer did not recognise her. Seeing only her bow, gun, and conning tower she appeared like three small boats, and he hastily made for the beach to hide again amongst the rocks. Once ashore, however, he discovered his mistake, and hailing his deliverer, he once more took to the water. So after a short swim he was picked up in the last stage of exhaustion and his daring adventure came to a happy end…

 

Later in his career, Lt D'Oyly-Hughes rose in rank to command HMS Glorious, an aircraft carrier, but died when it was sunk by the Scharnhorst in WW2.

Interestingly I have also found a report of another, similar operation from a second British submarine, the E2 , a few weeks later in September 1915.  First Lieutenant H.V. Lyon from HMS E2 swam ashore near Küçükçekmece (Thrace) to blow up a railway bridge. The bridge was destroyed but Lyon failed to return.

 

In WW2, the British Navy also employed this tactic in the Mediterranean. On 28 May 1941 Lt Dudley Schofield led a raiding party of 8, deployed from HMS Upright to attack an Italian railway line with pressure initiated explosives. I can find little description of the device other than it used "pressure pads". A month later, on 24 June Lt Schofield, who had adapted his techniques from lessons learned, went ashore with one  other and planted explosives on the Naples-Reggio di Calabria line. The charge failed to be initiated by a train so Schofield went ashore the following night to detonate the charge manually. Similar operations continued with Lt Wilson, (Royal Artillery) and Marine Hughes put ashore by HMS Urge in Sicily where they succesfully planted a pressure initiated device on a railway bridge.  There were quite a few other similar attacks from HMS Unique and HMS Utmost and other submarines.   Some similar submarine sabotage operations took place in Norway.

The US Navy Sub that destroyed a train, with an IED

I've written a few blogs in the past about IEDs placed under train tracks, that the weight of the train triggers. As a reminder:

 

  • In the US Civil War, in 1864, the Union Army designed an IED (a "rail torpedo") that initiated when a train ran over a rail , pressing down on a gun trigger that caused the device to function.
  • Another IED design was used in the Franco-Prussian War, in 1870, with the rail pressing on an artillery fuse to initiate the charge.
  • In the Boer War, in 1901, Jack Hindon used devices under railways to attack British trains, using an upturned Martini Henry gun lock, with the rail bending under weight to press on the trigger which initiated an explosive charge.
  • In WW1, ordnance specialist "Bimbashi" Garland designed and deployed similar devices, again using an upturned gun trigger, and used by Lawrence of Arabia to great effect against the Ottoman Turk trains in Arabia.

 

I'm glad to say I've now found a similar device, with a great story, from WW2.   The use of the IED was effectively the ONLY US ground combat operation on the Japanese homeland in the entire war. (Noting that the attack took place in southern Sakhalin, which was considered a Japanese home island at the time) .

Late in the war, US Navy submarines begain to patrol very aggressively close to the Japanese mainland. One of the subs was the USS Barb, skippered by Commander Eugene Fluckley. The patrol in question started on 8 June 1945 and involved a variety of attacks including, unusually, firing rockets at Japanese targets from the deck of the surfaced submarine. After noting considerable Japanese railway activity on a railway line near the shore, a plan was developed to blow up a train by putting a team ashore at Karafuto from the submarine.

An improvised device was carefully designed.  As far as I can make out it was as follows:

 

  • The main charge was a 55lb super-Torpex "scuttling charge" held in reserve on the submarine for scuttling the sub in an emergency. The blasting caps used must have been the ones meant to be used with this charge.
  • Power was provided by two dry cell batteries.
  • The switch was a microswitch removed from some electronic equipment on board.
  • The batteries and circuitry were mounted inside an oil-can to protect it from the elements. Included was a "test circuit" to ensure safety.

 

The crew made careful calculations to estimate the deflection of the railway line  (7/10", which was adjusted on the operation itself to 1/4") and made an improvised gauge to help the setting of the switch. They also made improvised shovels to help bury the charge under the rails. An eight man team was put ashore in inflatable boats and made their way (with one or two adventures) towards the track.

The charge was succesfully initiated by a 16 carriage train and all the saboteur group escaped unharmed. Commder Fluckley ended the war as the most decorated officer in the Navy.

Bomb Alleys

I now have an ulterior purpose in this blog.  I’m considering writing a book on "the history of explosive devices” and doing so in a perhaps unusual way. I propose to write the book in three parts, each part describing a geographic journey.   I have probably 70% of the research done and readers of this blog will recognise parts of the content.
 
Part 1 describes a walk of perhaps a mile and a half. The walk starts at Westminster Abbey in London and finishes in a church just up the road in Trafalgar Square.  This journey highlights the fact that explosive devices have targeted the centre of government and power over a 500 year period, and also highlights early bomb squad responses.  
 
Part 2 describes a sea journey along the coast of Europe, beginning in St Petersburg and ending in Lisbon, Portugal.   It highlights how war and revolution has driven the development of explosive device design and tactics.
 
Part 3 is a car journey in the United States, starting in Connecticut and ending in Florida, highlighting the surprising thread of explosive device use throughout the history of the USA. 
On each case a short chapter will detail the events on the route with a map to provide the theme of a geographical context. I welcome your comments as to whether you might find this interesting or not and of course any incidents on these journeys I have omitted.
 
Part 1 - A walk from Westminster to Trafalgar Square

IEDs from 1630

At the moment I'm working on some early seventeenth century pyrotechnic and military manuals again, to re-visit the development of military rockets. (Not everything you have heard about Congreve as an inventor is true!). But in doing so I came across some interesting early IED designs that I had in my archive but deserve a post in their own right. Here's an interesting IED. Key here is the use of improvised shrapnel and the "spikes" which both add to shrapnel and make the device tricky to move.

and this - an explosive charge on a cart, so an early VBIED or vehicle bomb.  As I have done frequently before, this further discredits the idea that the Wall St Bomb of 1920 was the game changer in terms of the concept of a vehicle bomb use. These images are from a book published in 1630, 290 years earlier.  I have listed several other early vehicle bombs here and here . There were also ships (vehicles) and trains pre-dating 1920.
