Frederick Douglas
“There are at the present moment many Colored men in the Confederate Army doing duty not only as cooks, servants and laborers, but real soldiers, having musket on their shoulders, and bullets in their pockets, ready to shoot down any loyal troops and do all that soldiers may do to destroy the Federal government and build up that of the rebels.”
And Frederick Douglas knew that how? Also, that quote dates from September 1861. How many black troops did the Confederates have then?
