Lincoln's statement, however, did not satisfy the Confederacy, and on April 12 they attacked Fort Sumter, a federal stronghold in Charleston, South Carolina. Federal troops returned the fire. The Civil War had begun. Immediately following the attack, four more states -- Virginia, Arkansas, North Carolina, and Tennessee -- severed their ties with the Union. To retain the loyalty of the remaining border states -- Delaware, Maryland, Kentucky, and Missouri -- President Lincoln insisted that the war was not about slavery or black rights; it was a war to preserve the Union.
