Footnotes

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.
