And you mention an "Act of February 17, 1864 - 4,000 - 5,000." What was this act and did it entail the enlistment of said blacks as soldiers or laborers?
'CHAP. LXXIX.--An Act to increase the efficiency of the army by the employment of free negroes and slaves in certain capacities.'
It was basically an Act that authorized the Confederate government to impress free negroes and slaves into non-combatant services such as teamster. They were not combat soldiers and I am sure @19thGeorgia who seems like someone who has done a lot of research on this matter knows that too.
This tiresome debate basically stems from the problem that some people just can't get over the fact that the Confederate government officially refused to use blacks as combat soldiers until March, 1865 - only a few weeks before the end of the Civil War.
By the way, Merry Christmas to all
