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. Many thanks to Mr Lindsay Spence for voicing our archival documents. Image: Herbert Olivier, Operations Room: Bomber Command Conference. Oil on canvas, 1944.
