Overview
Frederick Augustus, Count Rutowsky (also written Rutowski) (Warsaw/Dresden [?], 19 June 1702 – Pillnitz, 16 March 1764), was a Saxon field marshal who commanded Saxon forces in the Siege of Pirna during the Seven Years' War.
Life
Early years
He was an illegitimate son of August the Strong, King of Poland and Elector of Saxony, and his mistress Fatima (or Fatime) who was of Turkish origin. His mother was captured during the Battle of Buda by Hans Adam von Schöning. After Fatima became the King's mistress, she was christened Maria Anna and moved to the Dresden court.
The child got the name of his father, but shortly after the birth Fatima was married at the instigation of Augustus to his chamberman Johann Georg of Spiegel. Frederick Augustus moved to the estates of the Spiegel Family, but his father cared about his education, which led him among other things to go to Paris, where he found his half-sister Anna Karolina (the later countess Orzelska) and brought her to Dresden.
