True, that was an awkward episode. Now you've got me reading about the motivations for the civil war. I mean obviously slavery, but why go to war rather than let the Confederacy be a separate nation? Seems the fighting was over the political future of yet-to-be Arizona, New Mexico and Oklahoma (if I've got the right territories there), and whether they would have slavery, once populated.

Because the south decided to start shooting up Federal Forts and killing tax collectors.
