The Union army had at least 1 regiment from every Confederate state. That did not work in reverse. Having read all of Kurt Schlichter's recent novels about splitting up, I am not a fan. Everything gets worse and everyone gets poorer.The US Civil War did not have even close to 100% agreement within each state as to which side to join. Indiana had a fair amount of “copperheads” who were sympathetic to the Confederacy. Some of my wife’s distant relatives rode North from Tennessee and joined the US Tennessee mounted Infantry.
There were lots of votes against secession at the CW-era conventions. I seem to remember that "faithless electors" played a big part, in that they were sent to vote against secession and ended up voting for it.
