A Prussian officer, born at Magdeburg; joined Frederick the Great at Breslau, "a solid staid man, of a culture unusual for a soldier; brought with him his book, 'Memoirs Militaires sur les Grecs et les Romans,' a solid account of the matter by the first man who ever understood both war and Greek; very welcome to Frederick, whom he took to very warmly; dubbed him Quintus Icilius, and had his name so entered as major on the army books; promoted at length to colonel, a rank he held till the end of the war" (1721-1775). See Carlyle's "Frederick."
