Who was the American that captured British outposts at Vincennes?

George Rogers Clark captured Ft. Sackville and the Vincennes. Richard Henry Lee was a sub-commander under George Rogers Clark. It was Clark who actually won the battle of Vincennes after capturing Ft Sackville. Clark, through ingenious tactics that made it appear as though there were more American troops in Vincennes than what actually remained of his force, was able to keep the fort and the town surrounding it against overwhelming odds.
