Who Did Patton Draw Inspiration From?

The famed general of World War II, George S. Patton III, often spoke with pride of the military deeds of his forefathers. From an early age, Patton had been regaled with the exploits of the Pattons and their relatives from the War for Independence to the Civil War. These stories of courage and great deeds, of heroic men and mighty battles, greatly influenced the man who would dash his tanks across France.
Of all the courageous men spoken of, none stood taller in the eyes of the young Patton than his dead grandfather, Confederate Colonel George S. Patton I. This was the man the younger Patton regarded romantically as a noble fighter, who had displayed great bravery and honor in battle and had met his end at the head of his troops. So who was this unheralded soldier of the Civil War that Patton knew only through stories, but who helped to inspire him to become one of the great generals of World War II?
