black soldiers, sailors & marines filled every sort of job in all the various CSA units.
BTW, southron units (with the exception of 3 all-black units) were racially/ethnically/religiously INTEGRATED.
SLAVES, though frequently uniformed in rebel gray & armed, often went to war with their owners as "body servants". slaves were NOT however considered "members of the force", as slaves were not free to take the oath of enlistment.
the damnyankees only had SEGREGATED units, with lilly-white officers. BTW, the damnyankees, by law/regulation paid their black troops 1/2 the pay of whites; in the rebel military, we often couldn't afford to pay ANYONE, but when we had the money, ALL ranks (regardless of race,color or religion) got paid the same, according to their paygrade.

There is no credible of as many as one hundred.
