The bulk of the information in these notes was taken from two sources; V. E. Tarrant's The U-Boat Offensive 1914-1945, published by the Naval Institute Press, Annapolis, in 1989, and R. M. Grant's U-Boats Destroyed, published by Putnam, London, in 1964. Once compiled, these notes were compared in detail to a number of reputable references. Through this process it was determined that many differences exist between the different works, particularly concerning the cause of loss. In this record the best supported version has been used as the primary cause with the other incidents being listed as possibilities.
