Did there need to be a CSA? All alternate histories, and game mechanics, assume that if the Southern states break away they will form a Confederacy. Why?
After all, South Carolina's secession was to become INDEPENDENT and then it acceded to a new confederal organisation of states. Could it not have remained independent and just formed an alliance instead?
Was this idea mooted at the time, or in times past? Or was it always assumed by all that if the Southern states left they would form a union of their own?
