Mystery bombings

Fritz Joubert Duquesne was an inveterate anti-British spy who apparently used a number of IEDs to destroy British vessels sailing from South America in WW2.    Duquesne’s spying career started when as a British soldier serving in his home country during the 2nd Boer War, be was horrified at the British treatment of women and children.  His sister had been killed and his mother was dying in a British Concentration camp.

Duquesne then lived in the USA and became a German spy in 1914. He was sent to Brazil as “Frederick Fredericks” under the disguise of “doing scientific research on rubber plants.” From his base in Rio de Janeiro, he allegedly planted time bombs disguised as cases of mineral samples on British ships; he was credited with sinking “22 ships”. Among them, allegedly, were the Salvador; the Pembrokeshire; and the Tennyson and the “liner” Liger. One of his bombs allegedly started a fire on the Vauban.

I have been trying to find reference to the explosives planted on the British ships – little other than a reference to “infernal machines” in a press report. At the time numerous German saboteur plots were operating from N America (see earlier posts).

However, in investigating this I have found some discrepancies. For instance the SS Tennyson, was not sunk – it was still operating from Brazil in 1922. I can find no record of the “Liger” or a fire on the Vauban. The S.S. Pembrokeshire was “hulked” in 1913. Very curious. Was this a British misinformation campaign?

Here’s a press report of the time giving some details

Duquesne once again operated for the Germans in WW2, running the “Duquesne spy ring” which was broken by the FBI.

US C-IED and counter booby-trap efforts on the Battlefield – 1918

Further to my earlier post about German booby-traps on the battlefield in 1918 and the similarities to today’s IED threat, I’ve found the following typed document, a briefing paper, of sorts, from the office of the Chief Engineer of the General Headquarters of the American Expeditionary Forces in France in 1918. The document is titled “GERMAN TRAPS AND MINES” and describes the booby traps being encountered by American forces as the Germans retreated. Those of you with recent experience in Iraq and Afghanistan will recognise some of the phrases.

The document is a little faded, but I’ll make it as big as possible. It’s worth reading.

The Ingenious Bombs of Harry Orchard

A colleague put me on the trail of some interesting devices used in Colorado at the turn of the last century and I’ve found some interesting details about some very unusual IEDs.  In balancing the interests of readers and my natural disinclination to inspire any bomb makers I’m going to be a little vague about certain aspects of the design, so bear with me.

The perpetrator of the attacks was a man who called himself “Harry Orchard” but he had an awful lot of other aliases.  Orchard was involved in what are now called the Colorado Labor Wars, a struggle between mine owners and miners in Colorado in 1903 and 1904.

The dispute became more and more violent, and in that time and in that industry explosives and knowledge about their use was easily available.   Harry Orchard first became embroiled with this as a striker and then as a bodyguard to the miner’s leadership. He was a man with few scruples at the time.

IEDs had been used prior to 1903 by both sides – the mine owners had blown up the offices if a “Private Assay Office’ which catered for miners taking gold out of the mine for private sale – a practice called “high grading”.  And a mine workers association had blown up a mill in 1899. There were other incidents using explosives.

Orchard may have worked for both sides of the dispute – planting and laying IEDs in support of miners and also, for pay, for the mine owners as provocative acts.  In one attack Orchard assassinated the former Governor of Idaho, Frank Steuenberg.  There are a few sources about the various attacks that readers can find but for this post will concentrate on his IEDs.   The IEDs were constructed in a way that makes me think he was not an experienced “blaster, with experience from the mines.  In principle most of his devices used a very unusual and dangerous initiation system.  This largely involved using a bottle of acid, placed on its side over a sensitive component in an explosive train.  The acid bottle had a cork in it, and the cork was attached to fishing line.  Orchard then created a number of mechanisms to “pull” the cork, releasing the acid, which caused the explosion.

  • To create a command-initiated device, he ran the fishing line to a safe spot, and waited for his target to approach, then physically pulled the line, puling the cork from the bottle.
  • To create a booby trap, victim-operated device, he stretched the fishing line across the likely path of a victim, leaving the IED hidden beside the path.
  • To create a timed IED he attached the fishing line to the “key” at the rear of an alarm clock. When the alarm sounded (Orchard removed the bell) the key which wound the alarm element rotated, and wound the fishing line in, eventually puling out the cork from the acid bottle.

Orchard had a couple of other designs:

  • One used a pistol, aimed at explosives with fishing line attached to the trigger – for both a command pull and for a booby trap.
  • Another device was  a handful of blasting caps wrapped in burlap and then pitch so it eventually looked like a lump of coal, then the device was thrown onto the coal bunkers.

Here are some pictures of IEDs which he re-created as part of his confession.

 

This was the device used in the Steuenberg attack – but Orchard adapted it to operate by tripwire, leaving the clock element unused.

 

Orchard’s confession is available online –if you’d like details of where to find it let me know – but because it has detailed description of how he constructed the devices I won’t post it publicly.

Confederate IED organization

Careful reading of the excellent book “The sinking of the USS Cairo” by John Wideman, has allowed me to piece together some of the Confederate “IED” organization in the US Civil War and pull together some threads of incidents I’ve previously blogged about. Here’s a simplified summary with a series of links to the relevant posts

The leader of many such IED activities was Brigadier Gabriel Raines. Raines’s interest in IEDs went back to the Second Seminole Indian war in Florida, where he deployed IEDs against the Seminole Indians in 1840.

Gabriel Raines

Later, when the US civil war began he rapidly proposed the use of similar devices, and used them successfully in the retreat after the Battle of Williamsburg in 1862.

This book is a reprint of Raines technical notes about a number of munitions and IEDs.

Raines oversaw the Confederate use of such devices from the Confederate War department’s Torpedo Bureau (“Torpedo”) being a term that then covered a range of land and sea explosive devices).  At the beginning of the war, Raines’s devices were very much improvised, but eventually volume requirements and industrial processes evolved such that eventually many can be considered manufactured munitions.  Within the confederate forces the use of explosive devices was broad ranging and what follows is not the sum total, but there appear to have been two units.

The first was the Confederate States Navy submarine Battery service, under Hunter Davidson which appears to have been responsible for coastal defence sea mines and the like, often electrically initiated.  In  particular this unit had significant success on the James River. Later in the war attention turned to spar torpedo boats (boats with an explosive charge attached to a long spar which were used to ram enemy boats) . Hunter Davidson is an interesting character who I’ll write about in the future.  Here’s an angry letter he wrote in 1874 when some impertinent Brirtish Engineer officers claimed to have invented electrically initiated sea mines

The second unit, was commanded by the one-armed perpetrator of the sinking of the USS Cairo on the Yazoo River, Zere McDaniel

Zere McDaniel was responsible for

  •  Riverine IEd operations such as the sinking of the Cairo
  •  “Land torpedoes” in defence around Richmond, that used artillery shells adapted to detonate when stood upon (designed by Raines)
  •  “Behind the lines” IED and associated sabotage and intelligence operations.

The latter enterprises were as head of a Confederate secret unit “ Company A, Confederate secret service. The unit was formed in 1864 according to instructions that can be seen on this web page – a lovely document!

Some examples of the “behind the lines” operations included the explosion at City Point by Maxwell who reported directly to McDaniel and who used a time bomb or “horological torpedo”

Attacks on trains by Zere McDaniel himself using an IED which I’ll discuss in a future blog once I have found more detail.  Suffice to say that the initiation mechanism appears to have been an improvised wire hook which protruded from under the track and “hooked on” to the front of a passing train, probably pulling a friction initiator.

The confederate use of IEDs appears to have been positively encouraged and a secret law was passed awarding a bounty to confederate supporters who designed IEDs and used them to attack Union forces, awarding the designer 50% of the value of the target. McDaniel himself tried to claim for his attack on the Cairo, but failed in his appeal.   In 1864 McDaniel reported that his unit were engaged in continuous active operations , with elements operating “behind enemy lines” in Kentucky, Virginia and elsewhere

I see interesting parallels between the innovative use of munitions and explosive devices in the US civil war and the remarkable inventiveness of Syrian opposition forces in today’s Syrian civil war.
