Premise: Karl Ernst Manfred Freiherr von Richthofen (24 May 1855 – 28 November 1939) was a German "General der Kavallerie" (General of the Cavalry) during World War I and recipient of the order Pour le Mérite, known informally as the Blue Max. Richthofen was a great uncle of his more famous namesake Manfred von Richthofen, known as the Red Baron, who was his godson and named after him.
