Napoleon was great and he gets bonus points and added degree of difficulty because he had the French, but at the end of the day, you have to go with Alexander.
My favorites-Leonaides, Patton, and Charles the Hammer. Daniel Morgan has to get an honorable mention for the ass whupping he gave the Brits at Cowpens.
Glad to see you give the old wagoneer, Morgan credit. He understoon and knew how to use motivated but inexperienced volunteers. Of course receiving hundreds of lashes on his back by the British motivated him more than many. Most Americans do not know that without our victories at Cowpens and Kings Mountain, we might not have ended the Revolution successfully at Yorktown, even with the aid of the French Navy. In fact the Revolutionary War as fought in the south is severly underacknowledged in northern schools.
I am currently working on a novel taking place in 1799 which indicates some of what happened with Royalist fighters after they lost the war.
