About Robert Ritter von Greim
Robert Ritter von Greim was a German Generalfeldmarschall and First World War flying ace. In April 1945, in the last days of World War II in Europe, Adolf Hitler appointed Greim commander-in-chief of the Luftwaffe after Hermann Göring had been dismissed for treason. He was the last person to have been promoted to field marshal in the German armed forces. After the surrender of Nazi Germany in May 1945, Greim was captured by the Allies. He committed suicide in an American-controlled prison on 24 May 1945. Greim was promoted to Oberleutnant (First Lieutenant) on 17 January 1917. On 9 March 1915, Greim became an adjutant with the 1st battalion of the 8th Field Artillery Regiment. The request was approved on 28 October and Greim became a member of the Luftstreitkräfte (German Air Service). Greim became an ace on 16 August 1917, when he shot down a Sopwith 1½ Strutter.
