  • A New Look at the Dieppe Raid

    O’Keefe’s research began with the discovery of a single document connecting the existence of a special British intelligence unit and the Dieppe Raid. 78 years later the real objective comes out. the raid was to capture the new enigma machine with 4 rotors and associated prefixes etc.

    And that’s when I discovered this particular document that had been written – it was basically an in house history – a very short book about a unit called the 30th assault unit. But this was a particular unit that was raised to pinch or steal material that the cryptographers at Bletchley park who decoded the material would need.”

    “In the fourth paragraph there was a line that really caught my attention. The party at Dieppe did not reach its objectives. Now I was absolutely stunned because here was the first time that I ever had the document in my hand that directly connected Ultra....
    Interesting, thanks.

    Footnote: In Nicholas Rankins book Ian Fleming's Commandos, and later in a programme titled Dieppe Uncovered screened on the 19th August 2012, documents would appear to reveal that in fact an Intelligence Assault Unit was formed for the Dieppe Raid (19th August 1942) by Commander Ian Fleming RN and operated covertly on the raid as a Platoon of 40RM Commando under Lt H.O Huntingdon-Whitely (promoted Acting Captain on I5th Oct. 1942), their role to "pinch" signals intelligence documents, etc. from German Naval HQ at Dieppe. They did not achieve their objective.

    One of the documents discovered is titled "History of SigInt (Signals Intelligence) operations undertaken by 30 Commando, 30 AU", and in para 4 of that document it states " the party at Dieppe did not achieve their objectives".
    Lt. H.O. Huntingdon-Whiteley is here btw :

    We have an Image of a Signals Intelligence Unit [view] formed for the raid at Dieppe. It operated covertly on on this raid as a platoon of 40RM Commando. On that image he is named as a Lieutenant and commander of the unit and the image is annotated that he was later KIA. The unit was 10 Platoon 'X' Company [more...] under the command of Lieutenant H.O. Huntington-Whiteley , their role to acquire signals intelligence documents from German Naval HQ at Dieppe.

      What a terribly expensive failure.

        In his book, Winning the Radar War, Jack Nissen he says it was, in part, to capture components of a Freya radar a task he was assigned as a radar "expert." He was also one of the few, possibly only, RAF personnel assigned to the raid.

          There were multiple intelligence objectives in this raid. I recall reading about the radar examination in a book published in the mid 1970s. Specifically it was a account of Jack Nissen who examined the radar equipment.

          Another intel objective was to study the activation and use of German radio communications networks activated in response to the raid. The Brits had fragments of that from German tests and exercises, but were waiting to study a broad activation of the radio communications.

          Directly connected to that was a study of the messages activating units to give the Brits insight into the command structure and responses to a attack on the coast.

          The French underground and SOE on the ground were actively watching for similar intelligence on German actions.

          & of course they wanted to study the effectiveness of their tactics and weapons.

          Raids are a opportunity to secure a lot of insight into the enemy. A few months later the Brits had a similar intel capture when the convoys of the Eastern and Central Task Forces of Operation TORCH sailed south from the UK. Just before the convoys departed the Deception Committee tipped the Germans through their XX Cross agents. With the lie that the convoys might be headed to invade Brittany. The Germans alerted their entire defense of France, sent the two panzer corps in France to their anti invasion assembly areas, and filled the radio net with messages. The Brits spent months picking over that treasure trove of information captured from radio, photo recon, and agents in France. & not a single Brit soldier died on French beaches.

          After the convoys passed south a second series of messages were sent via XX Cross agents, that the convoys were destined for Egypt via Cape Horn. The KM dutifully started concentrating submarines off west Africa to intercept. Again Bletchley Park decrypted a fresh batch of messages related to this change in submarine patrol stations.

          Losing the war on the continent in 1940 caused the Brits to get serious about a number of things including their intelligence operations . It was a uphill slog and never perfect, but even in 1942 their coordinated and aggressive well planned operations were putting them well ahead of the dysfunctional mess the opposition had. So its almost a no brainier to know the Dieppe raid had a Enigma machine as a objective.
