I can see that. I have no problem with that but the fact remains that Lee took an oath .....
I'm sure that Lee felt his oath to Virginia superceded his oath to the USA, much like one's oath to the USA today supercedes one to the UN. I might also add that even though I am a southerner, I admire all the great men who fought in the Civil War, north and south. I even admire Sherman. I think his march to the sea was a brilliant campaign that probably shortened the war.
