You do know, I hope, that Ft. Sumter is in South Carolina, don’t you? And that South Carolina had seceded, and was no longer a part of the United States; and that Lincoln not only refused to peacefully leave Ft. Sumter, but instead had ordered it be reinforced and resupplied? THAT was an act of war, and before Beauregard ordered the bombardment of Sumter.

No, it is not "in" South Carolina, it is a man-made island built from the seafloor by the federal government. South Carolina had no right to it.

So, what you’re saying is that Ft. Sumter is outside the boundaries of the state of South Carolina? Who knew?
