General Lee. IMO, he was one of the only notable figures during the American Civil War to have any semblance of true respectability, and also was probably the best general of that time.

I was astonished to learn he felt he would have fought on the other side if his home state had chosen otherwise. Local patriotism was big then.
He also surrendered in the end to save his men, but only once it was clear the cause was hopeless. Respect!
