I didn't claim they fought in large numbers. I also didn't claim that slaves fought either.
I said blacks, and I meant blacks, and free blacks did fight as combat soldiers for the Confederacy. And while most were support personnel, there were still volunteers among the blacks to fill those roles, and to fill combat roles.
Denying it is not going to change the fact that there were some. Yes, more fought against the South than for. Yes, many slaves fled the South the first chance they got. But, that doesn't change history - and your insistence does not rewrite history.
The South had greater, long standing grievances with the North, over tariffs, taxes, trade, and divisive social differences than the North's threat of emancipation. Emancipation was a symbol for both the North and South, and became most relevant AFTER the war had started. But it was not the single, sole issue around which the question of secession revolved.
Even free blacks were not allowed to form regiments to fight for the Confederacy unlike those formed to fight for the United States though some mulattos may have tried to pass as white and join. Slaver leaders were unalterably opposed to Black soldiers since they would contradict the entire theory of slaver culture. This idea was maintained until the very end.
There have been many posts attempting to prove your claim none have been successful except to those who want it to be true.
There was NO threat of emancipation that was a Slaver lie. Abolitionists were NEVER in charge of the federal government even after the War started.
The ONLY reason the Slavers attacked the US was because of slavery. Emancipation was not an issue for the United States until well into the war and was not popular among many of those fighting to preserve the Union. The war was not fought between those wanting to get rid of slavery and those wanting to keep it but between those wanting to preserve the Union and those wanting to keep slavery. Read what the Slaver leaders said. They were very clear and totally unapologetic about it. At least in that they were honest.
Nor was the tariff much of an issue though the apologists keep trying to claim it was. Tariffs were universally acceptable as a means of financing the federal government and had always been. And the rate in 1860 was not at a historic high or going up. It is simply another attempt to excuse an unprovoked attack upon the United States by pretending that the Slavers had a just excuse for their idiotic attempt to destroy the Union.
