Transcripts of translations of secretly recorded conversations of ten German scientists detained by the British Government at Farm Hall, Godmanchester, England from May 1 through December 1945. The detainment was known as "Operation Epsilon," and the transcripts were sent as reports by the British military officers in charge to their superiors. These reports were then forwarded to the U.S. War Department through the military attache at the British Embassy. The scientists included: Otto Hahn who was awarded the Nobel prize for chemistry during his detention, Erich Bagge, Kurt Diebner, Walther Gerlach, Paul Harteck, Werner Heisenberg, Horst Korsching, Max von Laue, Carl Friedrich von Weizsacker, Karl Wirtz.
