Reread my post #84 above.
No, there were black slaves forced to serve the Confederate Army, tens of thousands of them.
Some were even forced to fire at Union troops, as the example I quoted in post #84 points out -- forced.
The most notable free black Confederate regiment was the 1st Louisiana Native Guards (CSA) -- all volunteers, unpaid, supplied their own uniforms & equipment.
They first formed on May 29, 1861 and were twice ordered by Confederate authorities to disband -- on February 15, 1862 and again on April 25, 1862.
The volunteer Confederate 1st Louisiana Native Guards served no purpose and fought no battles.
After the second order to disband, some of those previous Confederate troops joined the new Union 1st Louisiana Native Guards (USA), where they served & fought honorably.
Confederate 1st Louisiana Native Guards:
Death of Union free-black Captain Andre Cailloux, 1st Louisiana Native Guard (USA)), at the Battle of Port Hudson, May 27, 1863 
How about you respond to that particular point? That is the only point that really makes a hill of beans, isn't it?
Stranger thngs have happened in war. Jews fought for Hitler.

Does it look familiar?
