The last legal presentation of the Knight's Cross, in any of its grades, had to be made before 23:01 Central European Time 8 May 1945, the time when the German surrender became effective. A number of presentations were made after this date, the last on 17 June 1945. These late presentations are considered "de facto" but not "de jure" awards. In 1986, the Association of Knight's Cross Recipients (AKCR) acknowledged 7,321 presentations made to the members of the three military branches of the Wehrmacht—the Heer (Army), Kriegsmarine (Navy) and Luftwaffe (Air Force)—as well as the Waffen-SS, the Reichsarbeitsdienst (RAD—Reich Labour Service) and the Volkssturm (German national militia). There were also 43 recipients in the military forces of allies of the Third Reich for a total of 7,364 recipients. Analysis of the German Federal Archives revealed evidence for 7,161 officially—"de facto" and "de jure"—bestowed recipients, including one additional presentation previously unidentified by the AKCR. The AKCR names 890 recipients of the Oak Leaves to the Knight's Cross, including the eight recipients who served in the military forces of allies of the Third Reich. The German Federal Archives do not substantiate 27 of these Oak Leaves recipients. The Swords to the Knight's Cross were awarded 160 times according to the AKCR, among them the posthumous presentation to the Japanese Admiral Isoroku Yamamoto, 13 of which cannot be supported by the German Federal Archives. The Diamonds to the Knight's Cross were awarded 27 times, all of which are verifiable in the German Federal Archives. The final grade, the Golden Oak Leaves to the Knight's Cross was verifiably awarded once to Hans-Ulrich Rudel on 29 December 1944.
