South Carolina was the first state to secede from the Union (Dec. 1860), and was one of the founder members of the Confederacy (Feb. 1861). The bombardment of the beleaguered U.S. garrison at Fort Sumter in Charleston harbour on April 12th 1861 is normally reckoned as the first military engagement of the war.
