Actually, from my best info, the confeds were in the right. They absolutely-- and this I am CERTAIN of-- had the right to secede. Lincoln had no right to do the things he did to put down the South.. much less allow 600,000 killed over his cause. And the North was just as racist as the South, didn't want Blacks taking their jobs and etc..
The Northern soldiers would not have fought in the war (a lot of them) if they'd known it was about freeing the slaves. A lot of them didn't find that out until the bogus Gettysburg Address.. which Lincoln apparently did for political reasons, so he could get support for a not-going-2-well civil war...
