South Carolina attacked Fort Sumter…giving Lincoln an excuse to invade.only…South Carolina.
Suppose the other secessionist states said "You are at war with South Carolina only. Retake the fort by sea if you choose to, but we consider sending invading troops through our sovereign states to get there to be an unwarranted act of aggression.
In that case would the North be the one who decidedly started the Civil War? Or could the war have happened at all?
