The British-American spy tunnel extended approximately 330 metres from West Berlin into the GDR. From there, the intelligence services intercepted important telephone conversations between Soviet military personnel from May 1955 onwards. In total, over 400, 000 telephone calls were intercepted. The Soviet intelligence service ended the operation in April 1956. The story is well known in film and literature, but only almost. In fact, an important piece of the puzzle piece has been missing until now, slumbering in theŽarchives of Berlin's underground world. It is the comprehensive documentation that was produced exclusively for the GDR Minister of the Interior, Karl Maron. It was generally considered lost. In fact, it contains previously unknown photos and details about the discovery of this tunnel and how it worked. A real find. It is introduced and explained by Dietmar Arnold, who knows Berlin's underworld like no other, and Helmut Müller-Enbergs, who studies Berlin's spies, sometimes for counter-espionage, sometimes as a researcher at the Free University of Berlin. Der britisch-amerikanische Spionagetunnel ragte von West-Berlin rund 330 Meter in die DDR hinein. Von dort hörten die Nachrichtendienste ab Mai 1955 wichtige Telefongespräche der sowjetischen Militärs ab. In der Summe über 400. 000 Telefonate. Der sowjetische Nachrichtendienst beendete das Unternehmen im April 1956. Die Geschichte ist in Film und Literatur bekannt, aber nur beinahe. Tatsächlich fehlt bislang ein bedeutendes Puzzleteil, das in den Archiven der Berliner Unterwelten schlummerte. Es handelt sich um die umfassende Dokumentation, die allein für den DDR-Minister des Innern, Karl Maron, angefertigt worden war. Sie galt allgemein als verschollen. Tatsächlich enthält sie bislang unbekannte Fotos und Details zum Auffinden dieses Tunnels und dessen Arbeitsweise. Ein Fundstück. Eingeführt und erläutert wird es von Dietmar Arnold, der wie kein Anderer die Unterwelt von Berlin kennt, und Helmut Müller Enbergs, der sich mit Berlins Spionen befasst, mal für die Spionageabwehr, mal als Wissenschaftler der FU Berlin.
