First, wouldn't there have been other ads for "colored" C.S. military units? Second, are you familiar with the fate of that short-lived Choctaw command?
For those who don't know why this post is about Indians rather than mulattoes or negroes, I'm asking how Confederate military authorities in the Deep South reacted to men of "mixed blood" or color being recuited for front-line service.
David, I would like to see information about the book you mentioned.
