"Blacks fought for South but for states' rights, not slavery" by Walter Williams
Walter Williams: Accounts about black rebel troops draw fire
Williams wrote that in 1969. Amazing.
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?
They did, and it was.
