Rudolf von Hacklheber’s English is, in some respects, better than Shaftoe’s. He sounds unnervingly like Bobby’s junior high school drafting teacher, Mr. Jaeger. "Before the war I worked under Dönitz for the Beobachtung Dienst of the Kriegsmarine. We broke some of the most secret codes of the British Admiralty even before the outbreak of hostilities. I was responsible for some advances in this field, involving the use of mechanical calculation. When war broke out there was much reorganization and I became like a bone that several dogs are fighting over. I was moved into Referat Iva of Gruppe IV, Analytical Cryptanalysis, which was part of Hauptgruppe B, Cryptanalysis, which reported ultimately to Major General Erich Feilgiebel, Chief of Wehrmachtnachrichtungenverbindungen ."
