Can you back up that stat?
Thanks.
Of course he can’t. It’s not true.
Here's a site dedicated to the USCT of the Union Army. It indicates that of the 175,000 to 200,000 black soldiers, upwards of 138,000 were runaways from the confederacy or the border states. I make no claims for it's accuracy and I warn you in advance that the "Battle Hymn of the Republic" clip that it plays is very annoying. Link
Feel free to post anything you have that indicates otherwise.
