WW I German Field Code Manuals
Former USA Security Agency LTC Burt Slesinger (retired) donated eight post WW I US War Department training manuals to the NCM library. The AC Chairman stopped by Burt’s home in Melbourne, Florida to pick-up the items. The manuals contained detailed information on German Military Ciphers, Field Codes, and Military Liaison and Intelligence activities during the war. The items came from the collection of former ASA Col John Mcfadden (retired). Front cover photos of two of the manuals are included here.
