The truth is that the South seceded and fought to preserve slavery. That was the entire reason it seceded without the fear that their slaves were going to be taken away there would have been no rebellion. The North fought to preserve the Union. Most did not give a shiite about slavery, blacks, the idiot culture of the South or any other excuse given for them fighting. Lincoln mobilized to put down the insurrection aimed at destroying the Union.
The truth is the South wanted nothing to do with Black soldiers and resisted to the end enlisting them in any significant numbers. This is easily shown by the records of hundreds of thousands of Blacks fighting for the North in constrast to the words quoted by Whiskey Papa showing the contempt the Southern leaders showed to the idea of black soldiers.
The proportion of blacks fighting for the Cornfederacy was as high as the proportion of Jews fighting for the Nazis. Either was an extreme anomaly.
