The Confederate Congress outlines dire consequences for black Union soldiers and their white officers
Just before adjourning, the Confederate Congress laid down legislation dictating the treatment of African- American Union soldiers, and the white officers who led them, who became prisoners of war. Citing the dire consequences for the confederate states if slavery were abolished and "servile war" were to break our, the Congress authorized the return of black soldiers to slavery and the trial and execution of their officers for "inciting servile insurrection."
