From a specially equipped M Room in three stately homes deep in the heart of the English countryside, British Intelligence bugged the conversations of Nazi PoWs for the duration of the war. These grand houses were rigged with the latest and most advanced listening equipment. At the heart of this clandestine unit were German-Jewish émigrés who had fled Nazi persecution and were serving in the British army. In an ironic turn of events they became British Intelligence’s most valuable asset. They were the ‘secret listeners’ and spent up to twelve hours a day eavesdropping on the conversations of German PoWs; most significantly 59 German Generals. The results were to prove astounding and beyond anything Churchill imagined when he authorised unlimited funds in its set-up. Providing a detailed, oft humorous, insight into life of the Generals in captivity, the book shows the farcical ‘stage-set’ in which they found themselves. But against this backdrop, the secret listeners eavesdropped on admission of war crimes and terrible atrocities against Russians, Poles and Jews; as well as details of an SS mutiny in a concentration camp in 1936, and Hitler’s human ‘stud farms’. This story places firmly on record just how much British Intelligence knew about the Holocaust. Why, at the end of the war, were these files not released for the war crimes trials? These and other transcripts of some of the most important German military secrets of the war remained classified until 1999.
During their clandestine work the secret listeners did not set eyes on a single German PoW, yet their classified work and the intelligence they gained was as significant for winning the war as Bletchley Park and cracking the Enigma Code. For over sixty years the listeners never spoke about their work, not even to their families. Many went to their grave bearing the secrets of the nation which had saved them from certain death in the Holocaust.
