    During the second half of World War 2, the Allied air forces launched a large-scale heavy bomber offensive against German cities and war industries. This was designed to damage Germany's ability and will to continue the war. It also represented a way for Britain and the USA to support the Soviet Union before the D-Day invasion. The whole campaign was guided by intelligence, to identify the right targets, determine how badly they were damaged, and assess the effects on the German war effort.

    This huge undertaking taxed Allied intelligence capabilities to their limits. It has since become one of the many contended issues in the debates around this costly and controversial campaign.

    In this 'It Happened Here' episode, we are joined by Research Officer Dr Thomas Cheetham to explain the ways Signals Intelligence from Bletchley Park did - and didn't - guide Allied bombing strategy.

    Our thanks go to Owen Moogan and Sarah Langston for voicing our historical documents.

    Today GCHQ is an independent British intelligence organisation. However during World War 2, GC&CS, as it was then called, continued to be subordinate to the British Secret Intelligence Service, known as SIS or MI6. The Chief of SIS was also the Director of GC&CS.

    In this episode, we explore the relationship between the two organisations, the part that SIS played in supporting GC&CS, and the ongoing presence of SIS at Bletchley Park itself. Head of Content, Erica Munro, is joined by our Research Historian, Dr David Kenyon, and by a special guest - historian and expert on the wartime history of SIS, Dr Claire Hubbard-Hall.

    E183 - 'Ladies & gentlemen, go your ways!'

    In 1945, Britain celebrated VE Day in May and VJ Day in August, as the war - first in Europe and then the Far East - came to an end. For the staff of GC&CS and its larger worldwide network, this meant that the vital and exhausting work they'd been doing suddenly stopped. The lives of all of them had been changed forever, but each person's experience was different.

    Bletchley Park's Oral History archive is a treasure trove of Veterans' testimonies. In this It Happened Here episode, we will be digging into our sound archive to focus on how the workers reacted and what happened to them once peace was declared, in their own words. Our guide through these stories is Bletchley Park’s Research Historian Dr David Kenyon.

    This episode features the following Veterans’.

    E182 - "… and Peace at Last"
    Aug 22 2025
    August 2025

    On 15 August 2025 the UK commemorated the 80th anniversary of VJ Day, the day on which the surrender of Japan and the end of World War Two was announced.

    This was a significant moment at Bletchley Park as it meant the end of almost six years of non-stop codebreaking and intelligence work.

    For many it also brought an abrupt halt to years of training to learn Japanese and long journeys to reach postings in India, Sri Lanka and elsewhere in preparation for the upcoming invasion of Japan itself.

    In this ‘It Happened Here’ episode we are joined by Bletchley Park’s historians Dr Tom Cheetham and Dr David Kenyon to discuss how the Japanese war ended and the part played by Bletchley Park and signals intelligence.

    Our thanks go to Owen Moogan and Dr Ben Thompson for voicing our historical documents.

  • E181 - Blitzkrieg in Burma

    E181 - Blitzkrieg in Burma
    Jul 23 2025
    July 2025

    By late 1944, the tide had turned against the Japanese in south-east Asia, with the repulse of their attempted invasion of India. However, the multi-national Allied forces in Burma still faced enormous challenges if they were to retain the initiative, and push the enemy out of the country.

    Every mile travelled from their supply bases, across barely-navigable expanses of jungle and mountain, exposed Allied troops to greater difficulties and risk of starvation and destruction. It was a struggle against the terrain and a race against time to liberate Burma before the arrival of the monsoon. In this struggle, intelligence and deception were essential weapons in the Allied arsenal.

    In this It Happened Here episode, Head of Audiences and Programmes Vicki Pipe is joined by Research Officer Dr Thomas Cheetham to explore the 1945 battles for Burma and the race to Rangoon which formed the climax of Britain’s war against Japan.

    This episode features Veteran’s Eric Rhodes, Roy Buckmaster and Dennis Underwood, from our Oral History archive.

    Our thanks go to Owen Moogan and Dr Ben Thompson for voicing our historical documents.

    In May 1945 the Royal Navy fought its last surface action against the Japanese fleet, sinking the cruiser Haguro in the Mallaca Strait, off the coast of Malaya.

    The successful location of the enemy ship was the result of signals intelligence. It was also a product of the sophisticated network built up by Britain, the USA and Australia after 1943 to intercept, decipher and distribute intelligence around the Pacific and Indian Oceans.

    In this ‘It Happened Here’ episode, we are joined by Bletchley Park’s Research Historian Dr David Kenyon to discuss the role of the Codebreakers in this milestone on the road to ultimate victory over Japan in 1945.

    This episode features Veteran Edward Simpson from our Oral History archive.

    E179 - Dollis Hill Days

    May 2025

    During World War Two, Bletchley Park collaborated with several external engineering institutions in developing the famous codebreaking machines, such as the Bombes and Colossus.

    One such institution was the Post Office Research Station at Dollis Hill in London. In 2022, the previously secret war diary of the Research Station were released online to the public by BT, the successor to GPO Telecommunications.

    In this episode we are joined by James Elder, an archivist from BT Group Archives, as well as our own Research Historian, Dr David Kenyon, to find out what information the diaries can reveal about this secret collaboration.

    Many thanks to Dr Ben Thomson for voicing extracts from the War Diary.
