Alfrēds Riekstiņš, Latvian military officer and freedom fighter (d. 1913)
The Knight's Cross of the Iron Cross (German: Ritterkreuz des Eisernen Kreuzes) and its variants were the highest awards in the military of the Third Reich during World War II. The Knight's Cross of the Iron Cross was awarded for a wide range of reasons and across all ranks, from a senior commander for skilled leadership of his troops in battle to a low-ranking soldier for a single act of extreme gallantry. A total of 7,321 awards were made between its first presentation on 30 September 1939 and its last bestowal on 17 June 1945. This number is based on the analysis and acceptance of the Order commission of the Association of Knight's Cross Recipients (AKCR). Presentations were made to 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.These recipients are listed in the 1986 edition of Walther-Peer Fellgiebel's book, Die Träger des Ritterkreuzes des Eisernen Kreuzes 1939–1945 — Die Inhaber der höchsten Auszeichnung des Zweiten Weltkrieges aller Wehrmachtteile — The Bearers of the Knight's Cross of the Iron Cross 1939–1945 — The Owners of the Highest Award of the Second World War of all Wehrmacht Branches. Fellgiebel was the former chairman and head of the order commission of the AKCR. In 1996 a second edition of this book was published with an addendum delisting 11 of these original recipients. Author and historian Veit Scherzer has cast doubt on a further 193 of these listings. The majority of the disputed recipients had received the award in 1945, when the deteriorating situation of the Third Reich during the final days of World War II left a number of nominations incomplete and pending in various stages of the approval process.Listed here are the 448 Knight's Cross recipients of the Wehrmacht and Waffen-SS whose last name starts with "R". The AKCR named 447 recipients. Scherzer has challenged the validity of 11 of these listings but also identified one additional legitimate recipient, Siegfried Rieger. The recipients are initially ordered alphabetically by last name. The rank listed is the recipient's rank at the time the Knight's Cross was awarded.
