And it's amazing that with all those bazillion black soldiers fighting for the Confederacy that after the war the Southern states chose to thank that service by implementing a set of laws known as the Black Codes that returned every Southern black to as close a condition of slavery as was possible. Even those who had been free for generations. Why was that? Did you blame the black soldiers for the loss or something?
BTW, have you ever heard of indentured servants? Seems that was pretty popular in the North (another form of legal slavery except it was inflicted on Irish immigrants.)
