1947 and 1948 Postal IEDs – The Stern Gang

A friend pointed me in the direction of recently declassified MI5 files, now officially and publicly available. One set of hitherto SECRET and TOP SECRET papers relates to a series of attempted IED attacks on British targets in 1947, by the Stern Gang, in the run up to the Israeli declaration of Independence in 1948.  If you have the patience, there is an 88Mb download available at this link.   For those of you with an interest in technical matters, the report by Her Majesty’s Inspector of Explosives on one device, planted in Dover House, Whitehall, London on 16 April 1947 is on page 239.

The devices largely failed for technical reasons. However later IEDs in 1948 were not all failures.

Elsewhere in the released documents, historians will find some of the material fascinating.  MI5 demonstrably retained some of its star security officers from WW2,  and they were involved, in part, in this case – people like “TAR” Robertson who ran the “Double Cross” counter intelligence operation against the Nazis in the War.

There’s some fascinating reporting of its time – telephone operators overhearing suspicious conversations, members of the public reporting concerns, police surveillance operations and pre-digital secret bureaucracy. It is interesting to see the 1947 version of inter-agency counter-terrorist coordination between Foreign Office, MI5, police forces, Special Branch and others.

A later file from 1948 is also available for download (post the establishment of the State of Israel) and others clearly can now be accessed. In May 1948 the Stern gang sent a postal IED to Captain Roy Farran of the SAS (who was accused of murdering Alexander Rubowitz)  The package (addressed to R Farran), was opened by Roy’s brother Rex, killing him.

ECM Circuit Diagram

I’m pretty certain this is the circuit diagram for C-IED ECM I used in the late 80s and early 90s.  I certainly remember my ECM operator telling me about the magic smoke. From the excellent http://xkcd.com/730/

Sausage Cohen – Four Wars and a lifetime of Crowded Hours

Sos Cohen is another of those men from history and whichever way you look at it his story is pretty remarkable.  “Sos” is an abbreviation of his nickname “Sausage”.   Lionel Frederick William Cohen was born in 1875 in Newcastle-upon-Tyne.  At the age of about 14 he ran away from home and joined the Royal Marines Light Infantry. (That was his first military engagement.)  Eventually he was tracked down by his horrified family who insisted on buying him out and bringing him home.

His family then sent him to work as a clerk for an uncle in Johannesburg. He was bored by that, ran off, and at the age of 17 became a guard for a mining company.  Seeking adventure he then joined as a volunteer in the campaign against the Matabele, (his first war) with the now historical figures of Selous and Jamieson.  He took part in the Battle of the Shangani River in 1893 where he fought with fixed bayonets.   After other adventures in Africa he then became involved in the Boer War  in 1899 (War Number 2), where he worked as a undercover special force commander in Mozambique preventing arms being delivered to the Boers, reporting via the Mozambique authorities to his British controllers.

When that war ended he returned to civilian life and had more adventures.   When World War 1 (his third war) began he joined the 1st South African Horse as a 2nd Lieutenant.   He fought in German East Africa. At one point he and a single troop captured 430 of the enemy.  After this, now promoted to a “special service” Captain he took his troop behind enemy lines on intelligence missions. In 1916 he was attached to the Royal Naval Air Service (RNAS) as an airborne observer. He was involved in several skirmishes and crashes. In 1917 he formally joined the British Field Intelligence Force, again working behind enemy lines.  He ended the war as a major, with an MC and a DSO  and was mentioned in despatches three times.

By 1937 he was living in England and played a key role in setting up the RAF Volunteer reserve. He was commissioned into the RAF as a Pilot officer in 1939, aged 64. WW2 being his fourth war and at least his fourth service.  He served was a liaison officer from RAF costal command with the Royal Navy.  In this role he flew 70 operational missions as an observer or air gunner.  He reached the rank of Wing Commander and took part in bombing action against the Scharnhorst over the port of Brest in 1941, and other missions that sunk U-boats.  As a senior officer on liaison he was not meant to fly , but insisted on it. He received the DFC (Distinguished Flying Cross) in 1944, his 70th year.  He was mentioned in despatches twice more.  He died in 1960 aged 85.

I have omitted a lot of his adventures outside of the services, which are equally extraordinary. You can read about them in his biography “Crowded hours

The joy of Col AD Wintle MC

Some people ask me why I intersperse my blog with odd tales of military eccentrics.  At this link is a reason why. I posted an article some time ago about one of these characters, Col AD “Freddie” Wintle MC.  This audio archive is 16 minutes of utter, complete joy, full of the most outrageous quotes.  Enjoy it.

Wintle is recorded in 1962 as a guest on Desert Island Disks. He’s asked “Have you ever been on a remote desert island?” and he answers “Not if you don’t count Ireland”.

He’s asked what luxury he’d like to take to the Desert Island , and he says he’d like to take a dog whip, “In case any Germans landed”.  You will laugh too about the end of his hunger strike.

The IED Technology of Propaganda of the Deed, 1884

There’s a lot of attention given these days to the dissemination of such things as “Inspire” the extremist jihadi online magazine about how to build bombs and such like.

The truth is that this, like terrorism itself, is nothing really very new.  In 1884 the anarchist Johann Most published “Revolutionare Kreigswissenshaft”, a self proclaimed scientific handbook for would-be revolutionaries.  Johan Most popularized the concept of “Propaganda of the deed.”

While the modern day jihadist spreads his technology concepts by such things as “youtube”, “web forums” and “on-line magazines”,  Johann Most used “printing presses” and “bookshops” and “newspapers” to the same effect.

Most and his work are an interesting tale.  Most was born in Germany in 1846, and lived in England for a few years from 1878. Some of those English years were spent “at Her Majesty’s pleasure” in prison.  He was an ardent and open revolutionary. Finally he moved to the USA 1884, and was employed by an explosives manufacturer in New Jersey, building some small degree of technical expertise.  He published his book in 1884 and it is still available today still. I ordered mine openly from Amazon and I think I can justify it to the authorities.

The context of the situation in 1884 is important to understand.  My American friends will, I hope, forgive me when I say that it was a pretty easy place to build IEDs. A number of US citizens were openly involved in building IEDs for profit and training people to use them.

Here’s one example of a bomb maker from Philadelphia of the same period.  And another here from an earlier blog post on this site. .  I have records of several others including a man in Des Moines in the 1880s who was manufacturing IEDs to be sent to support the Fenian bombing campaign in London. Iowa was a hotbed of anti-British “Fenian”  feeling!   Then in 1886 was the Haymarket bombing in Chicago, which I have written about in an earlier post.

The Haymarket bombs were of a type described by Most in his handbook published two years earlier. There is a link, allegedly with Most promising to send the Haymarket conspirators dynamite. He really pushed the “classic” anarchist IED of a black sphere with a burning fuse projecting from it.

The truth is that Most’s understanding of explosives is nowhere near as good as he thought it was.  Perhaps that too is like modern extremist publications available on-line. The handbook has numerous technical errors but is all the more interesting for that. Clearly I’m not going into those errors here, but it’s pretty interesting to see his revolutionary ardour overtake technicalities. I would also add that most copies available are translations and I think there are some peculiar spelling errors and possible technical misunderstandings of the translator. For instance in the copies I have seen, Most describes “Oraini bombs”, which should I think read “Orsini bombs”. Also the translator clearly has no technical background – at one point complaining irritatedly that Most’s phrase “Cloral de pottage” doesn’t appear in any of the University of Arizona’s French Dictionaries. It clearly means Potassium Chlorate to anyone with a smidgen of understanding of the chemistry of explosives.

Most describes the manufacture of the chemical impact fuzing system that was in the IED used to assassinate the Tsar in 1881.

Interestingly Most advises that it is easier to obtain nitro-glycerine or dynamite legally or illegally than it is to manufacture it.   Amusingly, as a revolutionary, Most doesn’t describe it as “theft” but “confiscation”.   But then describing the manufacture of nitro-glycerine he views with disdain some of the safety measures that are normally advised for such projects.   Most’s instructions are not detailed or specific enough and are subject to dangerous misinterpretation, especially , I suspect, the translated versions, translated by a non-chemist who I don’t think has much technical understanding.

Most describes a way in which explosives should be used to cause damage to buildings and railway lines, but most of this seems to be a “cut and paste” job from Austrian military handbooks of the time. Again, somewhat like certain extremist sites of today who recycle conventional military handbooks.

Most does occasionally have some very pertinent ideas about such things as disguise of devices.

Most describes the manufacture of a range of explosive charges and also primary explosives and incendiary devices. There is an odd, and somewhat silly section about poisons, but no sillier, I suppose than some of the nonsense on extremist websites today.  I can’t really imagine copper acetate is a serious poison for the serious terrorist.   He also has ideas about operational matters such as organization of an operational terrorist group.

Most takes an interesting view on the question of the right to bear arms, which he equates directly with the right to possess explosives.  He attacks US lawmakers of the era who were trying to make the possession of explosives illegal, which he viewed as a first step along the road of making weapon ownership illegal.  “How then would the American revolutionary be able to shoot the lawmaker?”, he asks indignantly. Finally, Most describes some very “modern” OPSEC procedures.

So the history of disseminating terrorist technology and tactics goes back an awful long way.  Most was doing exactly what “Inspire” is doing now, just with a different level of media.  You’d be surprised at the similarities.
