If the best you can do is cite some obscure professor then I suspect your data is weak. Further, other than white does not mean black. Besides, your quote is "may" have been. You are really, really scraping the barrel here. Do you honestly want to claim that there were 90,000 blacks wearing the confederate uniform?
he was the expert on Black CSA servicemen, having spent over 25 years researching the service/pension/enrollment records.
as for my use of "may", NOBODY is SURE what the total number was, as too many service records have been destroyed over the last 150 years.
"an educated guess" from Professor Blackerby is somewhere between 100K & 150K Black volunteers. (fwiw, the difference is that SOME people-mostly "mixedbloods" MAY have been counted twice. for example a 1/2 Black-1/2 Indian MIGHT have been counted as BOTH.)
i KNOW this doesn't fit your wishes, but until/unless you can come up with something more FACTUAL than what you have so far presented, i'll stick with the expert's opinion/facts.
as for you, go read BLACKS IN BLUE AND GRAY, and you'll know MORE than you evidently do now.

Based upon growing up (for a time) in the South I would bet 10% were black. Now we have the question of choice in the matter. Russian "soldiers" fought in WW2 with guns on their backs.
