List of Knight's Cross of The Iron Cross Recipients of The U-boat Service - Footnotes

Footnotes

• a Sources are inconclusive with respect to date of death. Some sources indicate that von Forstner succumbed to his injuries on 22 October 1943 nine days after the sinking of U-402 on 13 October 1943.
• b Author Clemens Range dates Hans Lehmann's Knight's Cross on 8 June 1945, thus after the effectiveness of the Dönitz-decree. Walther-Peer Fellgiebel, author of Die Träger des Ritterkreuzes des Eisernen Kreuzes 1939-1945, indicates that Lehmann received the Knight's Cross on 11 May 1945, before the Dönitz-decree prohibited the awarding of the Knight's Cross. The sequential number 317 within the Kriegsmarine, 144 within the U-boat service, associated to Lehmann's Knight's Cross is based on author Clemens Range's work Die Ritterkreuzträger der Kriegsmarine and Busch and Röll's book Der U-Boot-Krieg 1939-1945 - Die Ritterkreuzträger der U-Boot-Waffe von September 1939 bis Mai 1945. Historian Veit Scherzer, whose work Die Ritterkreuzträger Die Inhaber des Ritterkreuzes des Eisernen Kreuzes 1939 von Heer, Luftwaffe, Kriegsmarine, Waffen-SS, Volkssturm sowie mit Deutschland verbündeter Streitkräfte nach den Unterlagen des Bundesarchives is based on the primary data from the German National Archives, indicates that the 7 May 1945 is the correct date.
