Battle of Fort Sumter - Siege and Political Maneuvers

Six days after the South Carolina government ratified an order of secession, U.S. Army Major Robert Anderson abandoned the indefensible Fort Moultrie and secretly relocated the 85 men under his command, companies E and H of the 1st U.S. Artillery[7], to Fort Sumter. Anderson had been appointed to command the Charleston garrison that Fall because of rising tensions. Anderson had been a protégé of Winfield Scott, the senior general in the U.S. Army at the time, and was thought more capable of handling a crisis than the garrison's previous commander. Throughout the autumn, South Carolina authorities considered both secession and the expropriation of Federal property in the harbor to be inevitable. As tensions mounted, the environment around the fort—which was located in what was still technically a constituent U.S. state—increasingly resembled a siege, to the point that the South Carolina authorities placed picket ships to observe the movements of the troops and threatened violence when forty rifles were transferred to one of the harbor forts from the U.S. arsenal in the city.

Many forts had been constructed in the harbor, including Fort Sumter and Fort Moultrie. Fort Moultrie was the oldest and was the headquarters of the garrison. However, it had been designed essentially as a gun platform for defending the harbor, and its defenses against land-based attacks were feeble; during the crisis, the Charleston newspapers commented that sand dunes had grown up against the walls in such a way that the wall could easily be scaled. When the garrison began clearing away the dunes, the papers objected. Fort Sumter, by contrast, dominated the entrance to Charleston Harbor and was thought to be one of the strongest fortresses in the world once its construction was completed; in the autumn of 1860 work was nearly done, but the fortress was thus far garrisoned by a single soldier, who functioned as a lighthouse keeper. However, it was considerably stronger than Fort Moultrie, and its location on a sandbar prevented the sort of land assault to which Fort Moultrie was so vulnerable
Under the cover of darkness on December 26, 1860, Anderson spiked the cannons at Fort Moultrie and moved his command to Fort Sumter. South Carolina authorities considered this a breach of faith and demanded that the fort be evacuated. At that time President James Buchanan was still in office, pending Lincoln's inauguration on March 4, 1861. Buchanan refused their demand and mounted a relief expedition in January 1861, but shore batteries fired on and repulsed the unarmed merchant ship, Star of the West. The battery that fired was manned by cadets from The Citadel, who were the only trained artillerists in the service of South Carolina at the time.

Following the formation of the Confederacy in early February, there was some internal debate among the secessionists as to whether the capture of the fort was rightly a matter for the State of South Carolina or the newly declared national government in Montgomery, Alabama. South Carolina Governor Francis W. Pickens was among the states' rights advocates who felt that all of the property in Charleston harbor had reverted to South Carolina upon that state's secession as an independent commonwealth. This debate ran alongside another discussion as to how aggressively the properties—including Forts Sumter and Pickens—should be obtained. Jefferson Davis, like his counterpart in Washington, D.C., preferred that his side not be seen as the aggressor. Both sides believed that the first side to use force would lose precious political support in the border states, whose allegiance was undetermined; prior to Lincoln's inauguration on March 4, five states had voted against secession, including Virginia, and Lincoln openly offered to evacuate Fort Sumter if it would guarantee Virginia's loyalty.[8] In March, Brig. Gen. P.G.T. Beauregard took command of South Carolina forces in Charleston; on March 1, Davis had appointed him the first general officer in the armed forces of the new Confederacy,[9] specifically to take command of the siege. Beauregard made repeated demands that the Union force either surrender or withdraw and took steps to ensure that no supplies from the city were available to the defenders, whose food was running out. He also increased drills amongst the South Carolina militia, training them to operate the guns they manned. Ironically enough, Anderson had been Beauregard's artillery instructor at West Point; the two had been especially close, and Beauregard had become Anderson's assistant after graduation. Both sides spent the month of March drilling and improving their fortifications to the best of their abilities.

By April 4, President Lincoln, discovering that supplies in the fort were shorter than he had previously known, and believing a relief expedition to be feasible, ordered merchant vessels escorted by the United States Navy to Charleston. On April 6, 1861, Lincoln notified South Carolina Governor Francis W. Pickens that "an attempt will be made to supply Fort Sumter with provisions only, and that if such attempt be not resisted, no effort to throw in men, arms, or ammunition will be made without further notice, [except] in case of an attack on the fort."

In response, the Confederate cabinet, meeting in Montgomery, decided on April 9 to open fire on Fort Sumter in an attempt to force its surrender before the relief fleet arrived. Only Secretary of State Robert Toombs opposed this decision: he reportedly told Jefferson Davis the attack "will lose us every friend at the North. You will wantonly strike a hornet's nest. ... Legions now quiet will swarm out and sting us to death. It is unnecessary. It puts us in the wrong. It is fatal."[10]

The Confederate Secretary of War telegraphed Beauregard that if he were certain that the fort was to be supplied by force, "You will at once demand its evacuation, and if this is refused proceed, in such a manner as you may determine, to reduce it." Beauregard dispatched aides to Fort Sumter on April 11 and issued their ultimatum. Anderson refused, though he reportedly commented, "Men, if you do not batter the fort to pieces about us, we shall be starved out in a few days.
