16. Dasch had given more than just Operation Pastorius to the FBI
During his extensive interrogations, Dasch provided the FBI with more information than just the workings of Operation Pastorius. The bureau collected useful information regarding the Abwehr, its contacts in America, German operatives and sympathizers, the training of agents destined for the United States, and more. Walter Kappe, who recruited the eight and ran the training program under Canaris, was described as intending to go to the United States following the success of Pastorius. Kappe intended to run subsequent operations from an American base.
Dasch had provided descriptions of many of the trainers and operatives of the Abwehr at the training camp west of Berlin. The information was confirmed and elaborated on by his colleagues, as each attempted to ingratiate himself with his captors. The FBI used the lists of contacts secreted on Dasch’s and Kerlings’ handkerchiefs to infiltrate groups of Nazi sympathizers. One of the more sobering aspects disclosed by Dasch, and confirmed by Kerling, was the requirement of the saboteurs to target Jewish owned department stores and businesses across the United States with bombs, making the public afraid to patronize them.
