There is a wonderful book that you ought to read that answers your question in great detail: Emancipating Slaves, Enslaving Free Men: A History of the American Civil War by Jeffrey Rogers Hummel.
I'll check it out, and I have one fro you.
Storm Over The Land by Carl Sandburg. An old book published back in the 30s, but worth looking up.
And I think WhiskeyPapa tourched Rebel Soldier's deer stand and Leesylvania's two seater privy out behind the big house.
Later. Got to go to the store.
