Another Clue in the Hunt for Robin William George Stephens

Joan Geraldine Pearson Dowling & Robin William George Stephens (from Camp 020 - Oliver Hoare)
Joan Geraldine Pearson Dowling &
Robin William George Stephens
(from Camp 020 - Oliver Hoare)
I had a comment on one of my Stephens blogs the other day from Stephen D. Stephen had tracked down a London Gazette notice dated 22 May 1942 relating to the second "wife" of Robin Stephens.

It would appear that Joan Geraldine Pearson Dowling may not have married Robin Stephens, but simply undergone a legal surname change in 1942. This would explain why I have been unable to trace a marriage registration for Joan and Robin.
Excerpt from the London Gazette - 22 May 1942
Excerpt from the London Gazette - 22 May 1942
The Gazette entry states:
NOTICE is hereby given that JOAN GERALDINE
PEARSON DOWLING of 36 Grafton Street, Lincoln
a natural born British subject intends after the
expiration of twenty-one days from the date of
publication hereof to assume the name of Joan
Geraldine Pearson Stephens.—Dated 19th May 1942.
     CHARLES ROBINSON and SON, 2, Lampton
(042) Road, Hounslow, Solicitors.
This discovery solves one lingering mystery. Still chipping away at the mystery of Robin Stephens' death registration (date, location, circumstances, etc.). Thanks to Stephen D. for sharing this discovery!

The Disappointing West Mercia Police Files on Bella in the Wych Elm

Worcestershire Constabulary
Last month, I ordered the West Mercia Police files on the Bella in the Wych Elm case. The price was a bit steep but... the idea of actually being able to access historical documents on the case was too tempting. The archivist at the Worcestershire County Archives admitted that the files contained quite a bit of duplication. That is a bit of an understatement!

So, here's what you get for £250...

ITV Crimestalkers VHS recording - 1994 - 10 minutes
"Uses a mix of acted reconstructions, interviews with witnesses, still images, World War II film and commentary by Mr John Stalker to tell the story of the discovery of the remains of a woman's body in a wych elm in Hagley Woods and speculate on possible course of events which led to the woman's death. Reconstruction of the events surrounding the discovery of the body with interviews with Bob Farmer and Bob Hart, two of the boys who discovered the body. Exploration of the witchcraft ritual angle including interview with Terry Wardle author of "Bygone Birmingham". Commentary on the writing which appeared on walls in the West Midlands about "Bella". Express and Star Newspaper Office records room with presentation of the "Anna" letter including interview with Jonathan Leake of the Express and Star. Exploration of the spy ring angle including film clips of parachutists and bombing of Coventry during World War II. Reconstruction of possible murder scenario." (from the Worcestershire County Archives catalogue of the West Mercia Police files on Bella in the Wych Elm)
The most interesting piece of the video is the statements from two of the boys (now elderly men) who found the skull in the Wych Elm. The rest of the video has some obvious inaccuracies and I'll do up a transcript of the video in a later post.

Original Documents
This is the mother load of documents but it has a few problems. Folders 2 and 3 are missing and were not included with the batch of documents sent to the Worcestershire Archives from the West Mercia Police. What did they include? Why were they not released? Questions with no answers.

There are many duplicates within the original documents as some reports and memos were produced in triplicate (or quadruplicate) in typical police fashion.

Whoever scanned the documents also tended to scan the reverse if it contained any writing. The documents written during the war often used recycled paper so the reverse side of the Bella documents might include various documents from the 1910s or 1920s which have no bearing on the Bella case.

Folder 1 - This folder contains the forensic examiners report and a variety of other police documents dealing with the shoes and the chalk writing. There is nothing in here related to the finding of body and/or the interviewing of the four boys or any other witnesses.

Folders 4 to 11 - These folders primarily deal with tracking down possible victims including some gypsies.

Folder 4 contains interviews with Una Hainsworth and statements from individuals who knew Jack Mossop. Folder 5 traces a woman by the name of Van Raalte. Folder 6 traces the contacts of Mary Lavin and Dinah Curley who were considered possible victims. Folder 7 deals tracks some gypsies in the area and chalk writing on walls. Folder 8 is focused on Mary Lee/Lea/Wenman/Beavers, a traveler reported missing by a couple of soldiers. Folder 9 has a bunch of press clippings about the case. Folder 10 traces various missing persons named Bella or Isabella. Folder 11 has information on Julian Mossop.

Loose - three loose pieces of paper that appear to come from the newspaper clippings folder.

Plastic Wallets -  There are a series of wallets that contain photographs of the wych elm, the skull, the lower jaw the reconstructed skeleton, the shoes, the ring and chalk writing on various walls and fences. Another series of wallets contain letters dealing with the case including the Anna to Quaestor letters as well as several with "tips" and information on possible victims/suspects of the case. Some letter writers claiming paranormal powers.

Ring Binder 1 - Murder at Hagley Wood - Bella file
The files from this binder contain an introduction and 10 sections. It appears to contain photocopies of the original documents although I have not gone through it in any great detail other than to rotate document images.

Ring Binder 2 - Photos and Press Cuttings
These all seem to be photocopies of the original photographs and newspaper clippings.

There are no files that document the finding of the body or interviews of the four boys. This is most disappointing as primary documentation is the holy grail of any investigation. The forensic examiner's report is included which is nice.

The Worcestershire County Archives noted that the police files included over 1400 scanned images. Given that the two binders are essentially duplicates of the Original Documents... and taking into account the "in-triplicate" tendency of the police and the presence of "recycled paper" scans.... we're probably looking at something more like 500-600 unique document scans.

One noticeable omission is the lack of any MI5 references within this set of files. Given Anna's claims of a spy ring, one would think that copies of reports, etc. would have been sent to MI5. If such was the case, there is no lingering reference within these files.

Over the next few weeks/months, I plan to examine the files in more detail and see what facts can be extracted from the documents and the press clippings.

The New and Improved Wandsworth Prison Museum

Old Wandsworth Prison Museum (Londonist site)
Old Wandsworth Prison Museum
(Londonist site)
Back in 2008, the Duke of Kent cut the ribbon on the official opening of the Wandsworth Prison Museum. The tiny museum, tucked in an old garage was stuffed to the ceiling with artifacts and documents from the more than 150 year history of  Wandsworth Prison.

The volunteer curator, a serving prison officer named Stewart McLaughlin, has tended the museum and its artifacts before and after that date.

In 2014, the museum shuttered its doors for several years while plans were put in motion for an expanded museum. Earlier this year, the new museum finally opened its doors.

Located off on Heathfield Road, in the north parking lot, the new building is much more spacious. Unfortunately, due to limited resources and the voluntary nature of the curator's position, the museum is only open by appointment. On the other hand, several Open House events have taken place since the museum reopened and there is always the potential for more.

I asked Stewart if he could send me some photographs of the museum and particularly the display around Josef Jakobs and the wartime spies. He kindly complied.

Below is a photograph of one of the display panels. It includes some page copies from the After the Battle magazine volume #11 - the volume that dealt with the World War 2 spies sent from Germany. The story of Karel Richter and his execution struggle (from After the Battle) are the two top images of the display. There are also two photographs in the top part of the display, one of Double Agent SNOW and one of Josef Jakobs, a copy of the photograph that I shared with Stewart.

London Bus Route 11 - Favourite Bus of Spies

Bus #11 passing around Trafalgar Square
(London Bus Museum)
The title of this blog is a bit of a stretch... it's hard to say if Route #11 was the favourite bus of spies but it was definitely the route that showed up twice in the MI5 files (so far).

When double agent TATE (Wulf Schmidt) radioed the German Abwehr in Hamburg that he desperately needed more money, they suggested a complicated rendezvous on Route #11 which involved Victoria Station. TATE replied that Route 11 didn't pass by Victoria (rather strange as it most certainly did) and suggested Route 16 instead.

One of the bus tickets found in
Engelbertus Fukken's possession
after his death.
(National Archives KV 2/114)
Around the same time, in early 1941, undiscovered spy, Engelbertus Fukken was taking Route #11 from Liverpool Station to Ludgate Circus and back. The tickets for his journey were found amongst his possessions after his suicide in an air raid shelter in Cambridge in late March 1941.

MI5 made enquiries and learned that the tickets actually had quite a bit of information contained within them:

Ticket #7974 (2d) - This ticket was issued on the 10th., March 1941, on a Route 11 Bus, leaving Liverpool Street on a journey westbound. The time of issue of the ticket would be a few minutes after 2-6 p.m. on the same date. The ticket would be available to Charing Cross.

Ticket #7374 (1 1/2 d) - This ticket was issued on the 10th., March, 1941, on a Route 11 Bus, leaving Shepherds Bush on a journey eastbound. The ticket was issued a few minutes prior to 3-26 p.m. on the same date, in the vicinity of the Bank or Ludgate Circus and would be available to Liverpool Street. (KV 2/114 - 18a)

Interesting that two different spies were connected with Route 11. There could of course be a very simple explanation...

Route 11 was, and still is, London's most famous bus route and with good reason. The route, originating near Shepherd's Bush and terminating at Liverpool Street, passed many of London's most famous sites. If one wanted to take a sightseeing tour of London, Route 11 was an excellent choice.

It passed through Chelsea, stopped at Victoria Station, wandered past Westminster (including Westminster Abbey, Parliament, Big Ben and Downing Street),  skirted Trafalgar Square and trundled past St. Paul's Cathedral and the Bank of England before terminating at Liverpool Street.

According to the London Transport Archives, the route, every day from 1941 to 1970 (with the exception of Coronation Day - 6 June 1953) was: Shepherds Bush, Hammersmith, Fulham, Waltham Green, Chelsea, Sloane Square, Victoria, Westminster, Trafalgar Square, Aldwych, Ludgate Circus, St Paul's Cathedral, Mansion House, Bank and Liverpool Street.

A reconstruction of the route based on those stops would most likely look something like the map below.

Google Map - showing location of Route #11 stops in London (purple markers) and likely route (blue line)

(Map available here)

Engelbertus must have been an adventurous soul to venture out onto the London bus system with his less-than-stellar identity papers. Was he to meet someone? Did he make other trips to London in the months before his death, trips for which he did not keep the tickets? Hard to say, but a tantalizing mystery.

A New Book - Double Agent CELERY by Carolinda Witt

Double Agent CELERY by Carolinda Witt
(from her website)
It seems that there are a slew of books coming out in recent years about wartime espionage and the characters involved. One of the newest, hot off the press books is entitled Double Agent CELERY - MI5s Crooked Hero by Carolinda Witt.

It turns out that CELERY, whose real name was Walter Dicketts was quite a character. He had six children via four wives and two mistresses - and none of the children knew of each other. The author of the book is one of his grandchildren who knew nothing about her grandfather until her mother passed away in 2007. Carolinda discovered another Dickett's grandchild on a genealogical forum and began to uncover the unbelievable story of Walter Dicketts.

Carolinda's book is being published today, 30 October 2017 (at least in the UK) by Pen & Sword books, with a foreword by Nigel West. The book will only be available in Canada in January 2018, so I will have to be patient.

The official write-up of the book on Carolinda's site states:
As Britain braced itself for the onslaught of a German invasion in February 1941, MI5 sent a handsome, womanising confidence trickster with a photographic memory, entrepreneurial flair, and nerves of steel to Lisbon to pull off the seemingly impossible.

MI5 wanted double agent Celery, an ex RNAS Officer called Walter Dicketts to persuade the Germans he was a traitor—then extract crucial secrets. With the clock ticking and his life on the line, Dicketts had to outwit his Nazi interrogators in Hamburg and Berlin and return safely to Britain—this time as a German spy. In what must count as one of the most heroic events of WW2, Dicketts managed to pull of the impossible only to discover he had been betrayed before he even left for Germany. It was a miracle he even survived…

Fluent in German and French, Dicketts was worldly and intelligent, charming and charismatic, and devastatingly attractive to women. Of his six wives, two were mistresses, and his six children knew nothing about the existence of the others. Sometimes rich and sometimes poor, Dicketts was an odd mixture of hero and crook, lover, and cad. The difficulty for others was in establishing who he really was.

His granddaughter Carolinda Witt pulls together family and official records, anecdotes and memories, police records and newspaper articles to tell the almost unbelievable true story of the most mysterious and fascinating British double agent during WW2.
It sounds rather intriguing. CELERY was involved with SNOW and it was their February 1941 trip to Lisbon  that tipped MI5s hand in retiring SNOW from his double agent duties. MI5 was never certain whose side SNOW was on. CELERY was indeed lucky to escape Germany with his life.

When the book becomes available over here, I'll post a review after I've read it. Stay tuned.

Media Review - Casefile True Crime Podcast - Who Put Bella in the "Witch' Elm

Casefile - True Crime Podcast - Case 4 - Who put Bella in the 'Witch' Elm (2017)

Original Air Date - 30 January 2016
Casefile - True Crime Podcast - Case 4 on YouTube
Duration - 31:48 minutes
Host - Anonymous

Yet another podcast on Bella in the Wych Elm! This one is put out by a team of Australians and is actually quite good. The team has several researchers who obviously know their stuff.

Although this is posted on YouTube, there are no still images which is, in many ways, a good thing, as they don't distract from the overall story. In the 13 O'Clock podcast, reviewed earlier, the still photos often had nothing to do with the case and their inclusion simply muddies the waters as we wonder... "Are those photos actually associated with Bella in the Wych Elm?".

The narrator of the Casefile podcast gives a very clear, very succinct summary of the case. Although the podcast is just over 30 minutes long, they do manage to cover quite a bit of territory and touch on all the different versions of events. Even, for example, they note that the taffeta found in the skeleton's jaw was not necessarily conclusive evidence of murder. The taffeta may have fallen out with the skull when it was removed from the tree by police, and been mistakenly placed in the jaw of the skeleton by an officer who thought it came from there. They podcast also references the possibility that the boys actually pushed the piece of the taffeta into the jaw of the skeleton when they were poking it with the stick. I have come across these variations in the story before but do wonder from whence they originate. Are they in the police files? Are these accurate and factual?

The show does note the provenance of the Donald McCormick speculations and admit that his research was rather "loose". Unfortunately, they do continue to propagate the errors that Allison Vale introduced into the case in 2013. They make the error of linking cabaret singer Clara Bauerle with one Klara Sofie Bauerle who visited England in the early 1930s. They quote the birth date for Klara Sofie Bauerle, which is not actually the birth date of Clara Bauerle. It is well documented that Clara Bauerle, cabaret singer, was born 27 August 1905 in Ulm, Germany. The host also continues the Vale errors by stating that Josef Jakobs was a Czech national. This is not accurate. Karel Richter (another spy) was the Czech national, not Josef Jakobs.

The podcast then delves into the Una Mossop and Van Ralt spy theory. Van Ralt was apparently a Dutchman who spied for the Nazis and bought secrets from Jack Mossop (Una's husband). Listening to the story, I once again wonder... (1) how did Van Ralt get money from Germany to pay Jack Mossop and (2) how did Van Ralt get the secrets back to the Germans? Never mind the fact that there is not a flicker of such a spy ring in the annals of MI5.

I do like the fact that the Casefile podcast details all the different variations of the story and notes which one are weak and unsubstantiated. They touch briefly on the witchcraft theory, the possible connection with the murder of Charles Walton (Pitchfork Murder).

They end the podcast noting that the skeleton and accompanying autopsy records were lost after being transferred to Birmingham University Medical School. Was it a conspiracy or a cover-up or an accident?

Apart from the unfortunate propagation of the Allison Vale errors, this was actually a very thorough and accurate summary of the Bella in the Wych Elm case. I also liked that there was only one narrator of the podcast. When there are two narrators, they end up kibitzing back and forth which detracts from the story, to my mind. On the whole, the piece was well-researched and gives a nice overview of the case.

Review Score
4.5/5 - very well researched with only a a couple of errors.

Mysterious Spy Transmissions from England to Germany

New mysteries always seem to be popping up in the quest for information on Josef Jakobs and the other World War 2 spies who arrived in England on behalf of Germany. The recent interest, both on this blog, and in the news about Engelbertus Fukken (alias Jan Willem Ter Braak) has led me down some interesting byways. Is there a possibility that Jan Willem did get some messages sent to the Germans?

Hamburg Messages
When Josef was interrogated at Camp 020, he told the officers that, during his training in Hamburg, in the Fall of 1940, he had been shown some agent messages by Boeckel (alias Dr. BEYER or BRUHNS). Josef said that Boeckel showed him the messages in order to demonstrate how they wanted the messages sent. According to Boeckel, these messages originated with their agents in England and had been sent to Germany via wireless transmitter. Josef recalled the contents of five of those messages and shared them with the Camp 020 officers.
Excerpt from a Camp 020 summary report of Josef's recollection of five messages that he saw in Hamburg,  supposedly originating from agents within England. (National Archives - KV 2/25, 94b)
Excerpt from a Camp 020 summary report of Josef's recollection of five messages that he saw in Hamburg,
supposedly originating from agents within England. (National Archives - KV 2/25, 94b)
The messages were as follows:
  1. Described the industrial buildings and factories in Coventry before the heavy air raid on that town took place. [the worst bombing took place on the evening of 14 November 1940] It was signed "107" [the agent number]. JAKOBS said he particularly remembered this number, because he asked Dr. BEYER at that time how they knew who had sent the message, and Dr. BEYER pointed to the number. He also remembered this message very well because when he saw it the papers were already full of the heavy air raid in Coventry.
  2. Apparently sent by a Swede, because it was written partly in English and Swedish. It contained a description of a factory that had recently been built here. The details were so exact that the Germans were able to pick out its position on a map. He could not remember the signature number.
  3. Described position of road barricades erected to hinder invaders. He could not remember the signature number.
  4. Contained descriptions of an aerodrome, and the message stated that the Germans could not use it because there was some kind of man-trap concealed , which turned over landing aeroplanes.
  5. Gave the names of ships lying in a certain dry dock. The names of ships seen on the sailors' caps at this particular port were also given, as the agent assumed that their ships must also be somewhere in the neighbourhood.
These messages naturally caused quite a stir at Camp 020 and within the Double-Cross system at large. Did all of these messages match up with MI5s double agents who had been transmitting information to the Germans?

Tracing the Hamburg Messages
Flt. Lt. Charles Cholmondeley
(From WW2 Database)
In early July 1941, Flight Lieutenant Charles Cholmondeley (pronounced "Chumley") conducted a thorough search of all the wireless transmissions that had been sent to Germany by MI5's stable of double-agents. Cholmondeley wrote a report which stated that, "having checked over the traffic, I find that we have no claim to Nos. 1 and 4. However 2, 3 and 5 may possibly have emanated from SUMMER and TATE".

Before we get into the three messages that Cholmondeley connected to SUMMER and TATE, it is helpful to remember that SUMMER (the Swede, Gosta Caroli) landed in the Northampton area and that, had he evaded capture, he was assigned to work in that general area. In his early transmission career with MI5, he transmitted from Aylesbury and later, from Hinxton Grange.

The second message that Josef remembered was:
2. Apparently sent by a Swede, because it was written partly in English and Swedish. It contained a description of a factory that had recently been built here. The details were so exact that the Germans were able to pick out its position on a map. He could not remember the signature number.
Here is what Cholmondeley dug up from the records of SUMMER's transmissions:
(2) 17 November 1940 by SUMMER [Gosta Caroli]
"Just back from Grantham.[A town in Lincolnshire, quite a ways outside of SUMMER's "officially assigned" stomping grounds.] Location of the factory which you gave not correct as Factory site indicated by you is Aveling and Barford [a manufacturing company on the outskirts of Grantham] where light tanks with Ford V8 engines are manufactured. [They did actually make some tracked carriers with Ford engines.] Twenty m.m. aircraft cannon are being experimentally manufactured by the British Manufacturers and Research Co. [Another manufacturer, also known as BMARC. They did make 20 mm anti-aircraft cannons.] This factory is situated west of Barford [the other company] and west not east of the railway. [This is accurate, BMARC was on Springfield Road.] 2000 employed in three shifts. Mainly Bren guns are manufactured. Going Birmingham Monday. [It would seem that MI5 portrayed SUMMER as getting around quite a bit.]

Google Map showing BMARC location (left marker),
Aveling & Barford Factory (middle marker) and
Grantham Aerodrome (right marker).
(From Google My Maps)
"Grantham Aerodrome is situated 2 km. south-east of the town, just before the road fork to Donnington. [Indeed it was. One can still see vague outlines of the airfield on Google satellite view.] It is built on top of a hill. It is said that it is invisible from 1000 m. up. There is one large and two small hangers 150 m. from the road. Entrances towards SSW adjoining NE of these are 6 hangars with entrances to the SSE. The landing field extends 1 km to the next cross-roads. 41 training planes and 5 Spitfires on field. No guards visible. Light Flak. NNE corner of the aerodrome."
Cholmondeley felt that the fifth message which Josef remembered could be linked up with another message from SUMMER. According to Josef, message 5:
5. Gave the names of ships lying in a certain dry dock. The names of ships seen on the sailors' caps at this particular port were also given, as the agent assumed that their ships must also be somewhere in the neighbourhood.
 The matching SUMMER transmission looked like this:
(5) 24 December 1940 by SUMMER [Gosta Caroli]
"Liverpool. In the town saw many sailors from HMS Sandwich [a Bridgewater class sloop launched in 1928] also from HMS Vernon [either a mine-laying tender HMS Skylark renamed Vernon in 1938 or the Navy's shore-based torpedo school called HMS Vernon] and HMS Australia [can't find a WW2 ship of that name - HMAS Australia commissioned 1911 was scuttled in 1924]. Heavy AA reported to be mounted on many ships in port.

and his transmissions. Top left marker is Liverpool.
Cluster of markers along mid-right is Grantham area.
Lower right marker (orange) is SUMMER's landing
site. (Blue markers are landing sites of other spies).
(Google My Maps)
While the November transmission about Grantham makes sense and falls within the time frame where Josef would have been at Hamburg for training, the message about Liverpool is a bit of a stretch. Josef told the interrogators that he went home for Christmas and he only spent a few days in Hamburg in early January before being sent on to The Hague. In addition, Josef said that the first message, about the bombing in Coventry, stuck in his mind as the newspapers were full of details about the bombing. This would suggest Josef saw the messages after mid-November, but within a week or two of the Coventry bombing (November 14, 1940). A message sent by SUMMER on December 24 does not fit these parameters.

As a side note, MI5 must have had quite the cover story for SUMMER to justify such far afield trips as Grantham and Liverpool. Mind you, as it turns out, double agent CELERY (a.k.a. Walter Dicketts) and double agent BISCUIT (a.k.a. Sam McCarthy) also apparently visited Grantham in the fall of 1940 on behalf of SNOW. (referenced in West & Madoc as well as Hayward) There is also some evidence that CELERY or BISCUIT were also taking on "missions" on behalf of SUMMER. Mind you, I am not a SUMMER or TATE expert. Interesting that Cholmondeley did not mention CELERY, BISCUIT or SNOW... Oh what a tangled web...

As for the third messages that Josef had seen, Cholmondeley figured that TATE or SUMMER was the most likely source for those.  Josef said that the third message:
3. Described position of road barricades erected to hinder invaders. He could not remember the signature number.
Cholmondeley found a series of messages, dated late October to early November which could correspond with the message Josef had seen. The maps below shows the main points described in the six transmissions (TATE is reddish markers, SUMMER is orange markers). The cluster from SUMMER are for an area between London and Oxford. The cluster from TATE center on an area north of London, near Hendon, coincidentally very close to Karel Richter's landing site (blue marker).
(3) 24 Oct 1940 - 25 Oct 1940 - 26 Oct 1940 by SUMMER [Gosta Caroli]
"Road blocks on all approached [approaches] to Thame. Searchlight and machine guns 5 km on the Thame-Aylesbury road near railway viaduct. Nearby in large field many obsolete cars to prevent landing. Strong road obstructions and tank stops of steel girders 2 km from Aylesbury and 400 m behind it there is a gun emplacement. I did not see any new airfields on the way.

"Main road between High Wycombe and Princes Risborough 1.5 km from Wycombe near the railway bridge, just past the fork to Oxford is a moveable barbed wire barrier. After passing the "Red Lion" at Bradenham there is, on the right side of the road, what I believe is as light A.A. gun emplacement. Close observation is not possible as there is a guard in the block house, but it looks as if a number of these emplacements extend round the hill on the right side of the road. On the road round the hill to Lacy Green and Speck (Speek)? I could see further road obstacles and gun emplacements.

"Details of locality refer to a journey along the main road from Thame to Aylesbury".
TATE also reported on similar blockades, tank traps and pill boxes in a series of messages about the Hatfield/Hendon area north of London.TATE was ostensibly based in a rooming house in Barnett, so this makes sense.
 (3) 30 Oct 1940 - 2 Nov 1940 - 5 Nov 1940 by TATE [Wulf Schmidt]
"Many factories damaged between Western Avenue and North Circular Road. Bomb 15 m. from centre cross-roads north Circular Road and Hendon Way. Much activity Hendon aerodrome...

"Barnett by-pass plane traps every 250 km. Barricades every 1.5 km usually old motor cars and barbed wire. Pillboxes at roundabouts. Pillbox junction Barnet Road and by-pass 2 km S. Hatfield aerodrome camouflaged represent advertising kiosk. Rumour new night flying bomber crew 6 or 7 and super armament.

"Tank traps on all main roads leading to Bignells Corner on Barnet by-pass also one pillbox commanding these four roads. All roads to Hatfield aerodrome are partly blocked and all fields within about 5 km round have wire traps across them."
Cholmondeley concluded that "in the case of (2) and (5), I feel the evidence is fairly good and leads definitively to the supposition that the messages were those sent by SUMMER, since JAKOBS particularly noted that in (2) the message was apparently sent by a Swede and in (5) there is direct reference to sailors' caps." Cholmondeley did not apparently feel that message (3) matched any particular SUMMER or TATE message exactly.

Major Thomas A. Robertson, the head of MI5's Double Cross system sent Cholmondeley's report on to Major Stephens at Camp 020. Robertson noted that while Cholmondeley thought that Messages 2, 3 and 5 could have emanated from SUMMER or TATE, Message 2 was problematic. SUMMER apparently transmitted in German and yet Josef had said that the message was a mixture of Swedish and English. Gosta Caroli (SUMMER) was Swedish so... not outside the realm of possibility but... he only transmitted in German, according to MI5. Regarding Message 5, the report from Liverpool, Robertson noted that Josef referred to sailor's caps which also occurred in SUMMER's message. This is a bit of a conundrum, since SUMMER's message, as contained with Cholmondeley's report, makes no mention of sailor's caps.

Interestingly, while some of the tallies (ribbons or bands) around sailors' caps had "HMS Ship's Name" on them, others simply said "HMS". This was a wartime security precaution - an attempt to confound German agents or sympathizers. Strange that MI5 would have sent such a message to the Germans. Unless, of course, British sailors, safe in a British port, were permitted to wear tallies with their ship's name.

So, we have five messages, two of which likely emanated from SUMMER or TATE and three which have no known double-agent source.
Message 1 - a message that described industrial buildings and factories in Coventry prior to November 14, 1940. Josef saw this message after November 14 but the news of the Coventry bombing was still fresh in the papers. MI5 admitted that this message had no known connection to any Double Agent transmissions.

Message 2 - sent in a mixture of Swedish and English - likely from SUMMER about his visit to Grantham (although CELERY went in early November too).

Message 3 - a fairly generic message about road barricades - likely emanated from either SUMMER or TATE.

Message 4 - a message describing an aerodrome with man traps to prevent the landing of German aircraft. MI5 admitted that this message had no known connection to any Double Agent transmissions.

Message 5 - a message about ships in dry dock and ship names on sailor's caps - MI5 thought this might be a SUMMER transmission from 24 December 1940 but, as mentioned above, it is unlikely Josef would have seen this particular transmission. He likely saw all five messages in mid to late November in Hamburg. Which means that this particular message is also not connected to a known agent transmission.
We are left with three possible scenarios out of this:
  1. MI5 didn't do a very good search of their double-agent transmissions and missed the ones that would match 1, 4 and 5.
  2. Messages 1, 4 and 5 may have originated with Juan Pujol Garcia (later double agent GARBO). Garcia got himself recruited as a German spy and while supposedly based in England, was actually living in Lisbon. Using newspapers and travel books, Garcia sent bogus reports to Germany about his "spying" in England, without ever leaving the comforts of his Iberian home. His messages were so accurate that when MI5 learned of them, they panicked and thought there was a spy on the loose in England. Garcia used secret ink, not wireless transmissions - so he is an unlikely candidate.
  3. Messages 1, 4 and 5 may have originated with a German spy unknown to MI5 - perish the thought. MI5 was quite confident, in late 1940 and early 1941, that they had scooped up all... or rather... most of the German agents.

    • There was the notable exception of Engelbertus Fukken (Jan Willem Ter Braak) who landed near Milton Keynes in early November 1940. MI5 did discover his parachute, which he stuffed in a hedgerow rather than buried, and knew that at least one spy had eluded their clutches. Fukken settled in Cambridge and remained at large until committing suicide in an air raid shelter in late March 1941. Upon discovering his wireless transmitter, MI5 couldn't decide if he had managed to successfully contact the Germans, or not. Could Messages 1, 4 and 5 have emanated from Fukken? The timeline would be about right, although he would have had to travel from Cambridge to Coventry within a few weeks of landing. Not outside the realm of possibility.
    • On the other hand... if one spy eluded capture, could there be another? Fukken committed suicide in a very public location, with his wireless transmitter conveniently deposited at Cambridge railway station's Left Luggage counter. Could another spy have evaded MI5s capture and then committed suicide in a far less public location? There is always the intriguing Trow Ghyll skeleton mystery which leaves one wondering. While Yorkshire is quite a ways from Coventry and the normal stomping grounds of Germany's spies... one does wonder. There is also the case of the Spy in the Attic, near Liverpool. 
    • Perhaps the messages originated from a British-born spy, someone who didn't need to parachute into England and risk capture. Perhaps some Nazi-sympathizer had a secret wireless transmitter with which they sent messages to Germany. This is a bit of a stretch and raises many questions. Where would the transmitter have come from? How would the Germans know on which frequency to listen for the transmissions? What sort of code would the agent have used that was known to both him/her and the Germans?
    • Which leads us to Double Agent, or is it Triple Agent or Quadruple Agent, SNOW, a Welshman who had been recruited by the German Abwehr and then MI5 and then the Abwehr... SNOW was a difficult agent to manage, for both sides. MI5 and the Abwehr always had doubts about whose side SNOW was really on... although some have said that SNOW was always on the side of SNOW! Could SNOW have sent some clandestine messages without MI5's knowledge? CELERY (Walter Dicketts) was of the firm opinion that SNOW had another line of communication with the Abwehr (other than the wireless sanctioned by MI5 (West & Madoc, p.108). In March 1941, after SNOW's trip to Lisbon, MI5 considered the possibility that he was communicating with the Abwehr via a means of which MI5 was unaware (West & Madoc, p. 168). It thus isn't outside the realm of possibility.
Another unsolved mystery, and one that likely haunted MI5 as well. At least two, and likely three of the messages, seen by Josef could not be traced to any known Double Agent. Who could have sent those messages? Were they from Engelbertus Fukken? SNOW? Or another, undiscovered German agent?

One last caveat is in order... this is all based on the assumption that Josef was telling the truth - something that is hard to establish with any degree of certainty. But if he did tell the truth, we have an intriguing mystery.
