text: List of Knight's Cross of the Iron Cross with Oak Leaves, Swords or Diamonds recipients of the Waffen-SS
Recipients -- Knight 's Cross with Oak Leaves and Swords
The Knight 's Cross with Oak Leaves and Swords is also based on the enactment Reichsgesetzblatt I S. 613 of 28 September 1941 to reward those servicemen who had already been awarded the Oak Leaves to the Knight 's Cross of the Iron Cross . The list is initially sorted by the chronological number assigned to the recipient .
The Knight's Cross of the Iron Cross (German language: Ritterkreuz des Eisernen Kreuzes) and its variants were the highest award in the military of the Third Reich. During or shortly after World War II, 457 German servicemen of the Waffen-SS, including volunteers from Belgium, Croatia, Denmark, Estonia, France, Hungary, Latvia, Netherlands and Norway, received the Knight's Cross of the Iron Cross. Of these, 411 presentations were formally made and evidence of the award is still available in the German Federal Archives. One recipient, Hermann Fegelein, was court-martialed and executed on 29 April 1945. According to German law he was deprived of rank and all awards previously. Fegelein must therefore be considered a de facto but not de jure recipient. A further 46 Knight's Cross, nine Knight's Cross with Oak Leaves and four Knight's Cross with Oak Leaves and Swords recipients are either lacking the evidence to sustain their listings or received the award under questionable legal terms. However, all of them were accepted by the Association of Knight's Cross Recipients (Ordensgemeinschaft der Ritterkreuzträger des Eisernen Kreuzes e.V.) as legitimate recipients.
