Some interesting WW II U-Boat war signals intelligence from the NSA (National Security Agency) Special Research Histories, available at: www.ibiblio.org/hyperwar/ETO/Atlantic/ scroll down to: The War Against the U-Boats - Special Research Histories. Select Vol I through IV, SRH 009 - SRH 008 - SRH 024 - SRH 025, and SRH 142. Blockade running U-Boats which is SRH 019, was also interesting.
