Maybe such a general didn't and couldn't exist: something to think about when people think about going to war.
The war that Lee wanted to fight wasn't one that he could have won -- not against Grant anyway.
His chief hope was that the other side would give up.
Which is the exact situation of that other famous slave owning general from Virginia who fought for Independence from a Union on behalf of a confederacy of slave owning states. :)
The meme that the South wanted to conquer that North is total BS fairy tale. The USA would have been fine either way with or without the South. The war was a choice and not necessity for the North. They fought it like that too.
