Recently a poster declared:
Secession had many causes, but none of them led to the war. Your proof positive is the Secession documents, which are nothing more than a list of grievances. So that being case, show proof using these documents that the war was fought over slavery. When you have done this I will show proof the issue was not slavery
The only event that leads to the war was Anderson moving from Moultrie to Sumter. Without that event there would have been no war.
