December 2024 On 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: Australian War Memorial (Public Domain) Accession Number SUK11808 #BPark, #Bletchleypark, #WW2, #Enigma, #Tirpitz,
