Bletchley Park

June 2026The story of the vital contribution of Polish codebreakers to the cracking of Enigma before World War Two is well known, but what happened to those codebreakers after the invasion of Poland in 1939?In this episode we follow the long and winding path of the Polish cryptanalysts from Warsaw to London. We also look more widely at the work done by the Polish Government in Exile in the UK to intercept wireless traffic and collaborate with Bletchley Park on signals intelligence.Head of Content, Erica Munro, is joined by our Research Historian, Dr David Kenyon.Our thanks go to Dr Ben Thomson for voicing our historical documents.For the interview we mentioned with Ferdynand Vanke, go to http://www.youtube.com/@csenigma1091 Image courtesy of Bletchley Park Trust#BPark, #Bletchleypark, #WW2, #Enigma, #Polish, #Poland, #Codebreaker,

June 2025In 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Veteran Edward Simpson from our Oral History archive.Our thanks go to Dr Ben Thompson and Owen Moogan for voicing our historical documents.Image: Public Domain#BPark, #Bletchleypark, #WW2, #Enigma,

April 2025To mark 80 years since the end of the war in Europe, this episode takes a closer look at four intriguing items from Bletchley Park’s collections. The team digs deeper into the stories that lie behind a mysterious message, a misunderstood photograph, a moving memo and audio of a Veteran’s memories of VE Day.Head of Content Erica Munro meets up with Research Historian Dr David Kenyon, Research Officer Dr Thomas Cheetham and Museum Archivist Dean Annison. Plus producer Mark Cotton speaks with former WRNS Bombe Operator Ruth Bourne about her VE Day memories.Many thanks to Dr Ben Thomson for voicing our archival documents.To see the objects we discuss in this episode, visit www.bletchleypark.org.uk/our-story/e178-ve80/Image: ©Bletchley Park Trust 2025#BPark, #Bletchleypark, #WW2, #Enigma, #VEDay80,

February 2025Here at Bletchley Park - one of the birthplaces of modern computing – our latest temporary exhibition ‘The Age of AI’ has just opened. This new gallery explores the power and potential of AI in our everyday lives. From the 1930s origins of what we now call ‘artificial intelligence’, to the incredible (or alarming?) potential it might bring, the exhibition explores the benefits and risks of AI in our world today.In this episode, Head of Content Erica Munro meets the team behind the exhibition’s creation. Come with us on a gallery tour with Exhibitions and Interpretation Manager Tilly Davis, and hear from experts and visitors on their impressions of what AI means to them. There’s also a deeper dive into the research and exhibition’s case studies with Content Curator Steve Swaby.Many thanks to our contributors Dame Wendy Hall, Dr Ed Pyzer-Knapp, Professor David Leslie and our Friends of Bletchley Park exhibition preview visitors.Image: ©Bletchley Park Trust 2025#BPark, #Bletchleypark, #WW2, #Enigma,

December 2024For this year’s festive episode, we once again put the word out to our listeners: what baffles you about Bletchley Park, and what myths and misconceptions would you like our resident Historians to investigate and interrogate?Bletchley Park’s Head of Content, Erica Munro, is asking the questions, with Research Historian Dr David Kenyon and Research Officer Dr Thomas Cheetham fielding queries on uncracked ciphers, captured codes, cribbing, declassification … and, of course, Christmas.Many thanks to Dr Ben Thomson for voicing our archival documents.Image: ©Bletchley Park Trust 2024.

November 2024On the 12th of 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.Image: Naval History and Heritage Command Catalog #: NH 71318#BPark, #Bletchleypark, #WW2, #Enigma, #Tirpitz,

October 2024The 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.This episode features the following Veteran from our Oral History archive:Sir Arthur BonsallMany thanks to Dean Annison & Mr Lindsay Spence for voicing our archival documents.Image: ©Bletchley Park Trust 2024.

August 2024Hut 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.Image: ©The Registration Room in Hut 6, Block D.
