re: #1 Alouette
I was just about to post this on the previous thread:
There was a unit from Louisiana called the “Native Guards” composed of “Free Men of Color” who volunteered for the Confederacy. Their services were rejected, and they became a Union regiment. However, their black officers were all replaced by white men.
Right, I know about them. This story reinforces my point. Not only were there no black soldiers fighting on the side of the Confederacy, the very few who wanted to were rejected by the South.
