Despite the Confederacy's declaration of independence, the United States Army still garrisoned a number of forts in the south. The most vulnerable was Fort Sumter in Charleston harbor, South Carolina, which desperately needed to be resupplied. However when newly elected US President Lincoln ordered the navy to ship in supplies, the Confederate government considered it an act of war and attacked the fort from land. The American Civil War had begun.
