    E172 - Hunting the Beast Part 1
    Nov 22 2024
    November 2024

    On 12 November 1944 Germany’s largest battleship – Tirpitz – was sunk by British RAF Lancaster bombers off Tromso in Norway.

    Ever since its deployment to the region back in January 1942, the battleship had posed a threat to Arctic convoy operations. A large part of the Royal Navy’s Home Fleet as well as US vessels were tied up protecting convoys from this ship that Winston Churchill christened ‘The Beast’.

    Despite Tirpitz having never fired its guns in anger at Allied warships, its presence was threat enough. Intelligence experts continued the difficult work of tracking its location and state of readiness.

    The analysts of Bletchley Park’s Naval Section followed the ship for nearly three years, and played a key part in her final destruction. In this ‘It Happened Here’ episode, we are joined by Dr David Kenyon, Bletchley Park’s Research Historian and author of ‘Arctic Convoys: Bletchley Park and the War for the Seas’.

    Many thanks to Dr Ben Thomson for voicing our archival documents.

  • E171 - Bletchley Park & Bomber Command Part 2

    E171 - Bletchley Park & Bomber Command Part 2
    Nov 8 2024
    November 2024

    The crews of RAF Bomber Command had one of the most hazardous jobs of the war. Flying by night to their targets in occupied Europe, they were alone and vulnerable to the prowling German night-fighters.

    Helping them reach their targets was one of the least-known, but most significant achievements of the signals intelligence operation at Bletchley Park. Analysis of the night-fighters’ communications revealed priceless insights into the German defensive system – and how it could be evaded, outwitted and ultimately manipulated.

    In this ‘It Happened Here’ episode, Bletchley Park Research Officer Dr Thomas Cheetham tells us about one of Bletchley Park’s most important contributions to Britain’s total war against Nazi Germany.

  • E169 - Learning the Ropes

    E169 - Learning the Ropes
    Sep 20 2024
    September 2024

    The Government Code and Cypher School employed thousands of people during the war. These varied from Cambridge dons who had broken codes in World War One to machine workers with very specific skills, to female conscripts from the three armed services.

    How did all these people know what to do? As usual at BP, the answer is a complex one: a mix of training courses (some well organised, others less so) developed as the organisation grew exponentially as the war progressed.

    In this month’s ‘It Happened Here’ episode we are joined by Bletchley Park Historian Dr David Kenyon to explore the varied experiences of new recruits finding out how to do their job – sometimes on an organised course, sometimes learning on the job, and sometimes literally making it up themselves.

    This episode features the following Veterans from our Oral History archive:
    Betty Webb
    Iris King
    Joan Joslin

  • E168 - Inside Hut 6

    E168 - Inside Hut 6
    Aug 29 2024
    August 2024

    Hut 6 was the section at Bletchley Park which broke the German army and air force Enigma ciphers. Historical accounts usually focus on the early part of the war, when a small and inexperienced team was established in a newly-built wooden hut.

    But by 1944 Hut 6 looked very different. It was a hardened unit of several hundred people, supported by cutting-edge technology. Hut 6 personnel had honed their methods through bitter experience against Enigma ciphers which continued to increase in both number and security.

    Recent research into Bletchley Park’s unique collections has revealed more about how this vital section worked. We have discovered how they kept the intelligence production line running despite fighting a daily battle not just against the ciphers, but against the dangers of inefficiency, poor morale and organisational friction.

    For this episode Research Officer Dr Thomas Cheetham is joined by Bletchley Park digitisation volunteer (and all-round brainbox) Craig Heath to take a detailed look inside Hut 6.

    Many thanks to Sarah Langston and Joel Desborough for voicing our archival documents.

  • E167 - The Forgotten Army

    E167 - The Forgotten Army
    Jul 31 2024
    July 2024

    In early 1942 one of the most disastrous defeats of the war saw British forces pushed out of Burma, now known as Myanmar. Two years later, the multi-national Fourteenth Army, the ‘Forgotten Army’, had learned to fight and beat the Japanese, inflicting their largest defeat of the war at Imphal and Kohima, and was poised to begin the reconquest of Burma.

    This turnaround had much to do with bitter experience gained in close combat, and superb logistics, but an important element was detailed intelligence, which allowed the Allies to seize control of the skies and control the battle below.

    In this ‘It Happened Here’ episode, Research Officer Dr Thomas Cheetham leads us through the transformations at Bletchley Park, at signals intelligence centres in South-East Asia, and on the front lines, which turned defeat into victory.

    E166 - D-Day80 Part 3 Block D to Bocage
    Jun 21 2024
    June 2024

    To commemorate the 80th Anniversary of D-Day, we are releasing 3 special episodes to tell the full story of The Longest Day. This third part is a brand new episode looking beyond the beaches.

    Bletchley Park made a vital contribution to the planning and preparation of D-Day, but the landings were only the beginning. There would be another three months of hard fighting in Normandy before the German forces finally cracked, and France could be liberated.

    Ultra intelligence from Bletchley Park gave crucial support to Allied commanders throughout the battle. But knowledge rarely translated directly into action. Those generals and airmen faced with the mammoth task of orchestrating a modern all-arms battle had to balance numerous competing priorities, of which intelligence was rarely the most important.

    In this episode, Research Officer Dr Thomas Cheetham has delved into the detail of five turning points, to explore exactly how – and how far – Bletchley Park contributed to Allied victory in the Battle of Normandy.

    Many thanks to Joel Desborough for playing the part of our RAF SLU Officer.

  • E165 - D-Day80 Part 2 Overlord

    E165 - D-Day80 Part 2 Overlord
    Jun 5 2024
    June 2024

    To commemorate the 80th Anniversary of D-Day, we will be releasing 3 special episodes to tell the full story of The Longest Day. This second part is a complete remastering of our original Overlord episode with the addition of much new content.

    80 years ago today, more than 150,000 Allied troops were boarding planes, gliders and landing craft as they prepared to invade Fortress Europe in Operation Overlord, the Normandy Invasion. Meanwhile, 200 miles away in the Buckinghamshire countryside the Codebreakers of GC&CS were also ready and waiting.

    Naval Section spent the day decrypting German messages and forwarding that vital intelligence to Allied commanders, in many cases only two and a half hours after the German operators had sent them.

    Today at Bletchley Park our Archive holds hundreds of these handwritten decrypts and using a selection of these we tell the story of The Longest Day. Our Research Officer, Dr Thomas Cheetham & Research Historian, Dr David Kenyon will be your guides, with the help of 12 of our Veterans’ memories from that eventful day.

    This episode features the following from our Oral History archive:
