The Battle of Fort Sumter (April 12–14, 1861) was the bombardment and surrender of Fort Sumter, near Charleston, South Carolina, that started the American Civil War. Following declarations of secession by seven Southern states, South Carolina demanded that the US Army abandon its facilities in Charleston Harbor. On December 26, 1860, Major Robert Anderson of the U.S. Army surreptitiously moved his small command from the indefensible Fort Moultrie on Sullivan's Island to Fort Sumter, a substantial fortress controlling the entrance of Charleston Harbor. An attempt by U.S. President James Buchanan to reinforce and resupply Anderson, using the unarmed merchant ship Star of the West, failed when it was fired upon by shore batteries on January 9, 1861. South Carolina authorities then seized all Federal property in the Charleston area, except for Fort Sumter.
During the early months of 1861, the situation around Fort Sumter increasingly began to resemble a siege. In March, Brigadier General P. G. T. Beauregard, the first general officer of the newly formed Confederate States Army, was placed in command of Confederate forces in Charleston. Beauregard energetically directed the strengthening of batteries around Charleston harbor aimed at Fort Sumter. Conditions in the fort grew dire as the Union soldiers rushed to complete the installation of additional guns. Anderson was short of men, food, and supplies.
The resupply of Fort Sumter became the first crisis of the administration of U.S. President Abraham Lincoln. He notified the Governor of South Carolina, Francis W. Pickens, that he was sending supply ships, which resulted in an ultimatum from the Confederate government: evacuate Fort Sumter immediately. Major Anderson refused to surrender. Beginning at 4:30 a.m. on April 12, the Confederates bombarded the fort from artillery batteries surrounding the harbor. Although the Union garrison returned fire, they were significantly outgunned and, after 34 hours, Major Anderson agreed to evacuate. There was no loss of life on either side as a direct result of this engagement, although a gun explosion during the surrender ceremonies on April 14 caused two Union deaths.
Following the battle, there was widespread support from both North and South for further military action. Lincoln's immediate call for 75,000 volunteers to suppress the rebellion resulted in an additional four southern slave states also declaring their secession and joining the Confederacy. The Civil War had begun.
On December 20, 1860, shortly after Abraham Lincoln's victory in the presidential election of 1860, South Carolina adopted an ordinance declaring its secession from the United States of America and by February 1861, six more Southern states had adopted similar ordinances of secession. On February 7, the seven states adopted a provisional constitution for the Confederate States of America and established their temporary capital at Montgomery, Alabama. A February peace conference met in Washington, D.C., but failed to resolve the crisis. The remaining eight slave states declined pleas to join the Confederacy.
The seceding states seized numerous Federal properties within their boundaries, including buildings, arsenals, and fortifications. President James Buchanan protested but took no military action in response. Buchanan was concerned that an overt action could cause the remaining slave states to leave the Union, and while he acknowledged there was no constitutional authority for a state to secede, he could find no constitutional authority for him to act to prevent it.
The forts of Charleston
Several forts had been constructed in Charleston's harbor, including Fort Sumter and Fort Moultrie, which were not among the initially seized properties. Fort Moultrie on Sullivan Island was the oldest—it was the site of fortifications since 1776—and was the headquarters of the U.S. Army garrison. However, it had been designed 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 piled 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.
Major Robert Anderson of the 1st U.S. Artillery regiment had been appointed to command the Charleston garrison that fall because of rising tensions. A native of Kentucky, he was a protégé of Winfield Scott, the general in chief of the Army, and was thought more capable of handling a crisis than the garrison's previous commander, Col. John L. Gardner, who was nearing retirement. Anderson had served an earlier tour of duty at Fort Moultrie and his father had been a defender of the fort (then called Fort Sullivan) during the American Revolutionary War. Throughout the fall, 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 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.
In contrast to Moultrie, Fort Sumter dominated the entrance to Charleston Harbor and, though unfinished, was designed to be one of the strongest fortresses in the world. In the fall of 1860 work was nearly done, but the fortress was thus far garrisoned by a single soldier, who functioned as a lighthouse keeper, and a small party of civilian construction workers. Under the cover of darkness on December 26, six days after South Carolina declared its secession, Anderson abandoned the indefensible Fort Moultrie, ordering its guns spiked and its gun carriages burned, and surreptitiously relocated his command by small boats to Sumter.
President Buchanan and the Star of the West
South Carolina authorities considered Anderson's move to be a breach of faith. Governor Francis W. Pickens believed that President Buchanan had made implicit promises to him to keep Sumter unoccupied and suffered political embarrassment as a result of his trust in those promises. Buchanan, a former U.S. Secretary of State and diplomat, had used carefully crafted ambiguous language to Pickens, promising that he would not "immediately" occupy it. From Major Anderson's standpoint, he was merely moving his existing garrison troops from one of the locations under his command to another. He had received instructions from the War Department on December 11, written by Major Don Carlos Buell, Assistant Adjutant General of the Army, approved by Secretary of War John B. Floyd:
... you are to hold possession of the forts in this harbor, and if attacked you are to defend yourself to the last extremity. The smallness of your force will not permit you, perhaps, to occupy more than one of the three forts, but an attack on or attempt to take possession of any one of them will be regarded as an act of hostility, and you may then put your command into either of them which you may deem most proper to increase its power of resistance. You are also authorized to take similar steps whenever you have tangible evidence of a design to proceed to a hostile act.
Governor Pickens therefore ordered that all remaining Federal positions except Fort Sumter were to be seized. State troops quickly occupied Fort Moultrie (capturing 56 guns), Fort Johnson on James Island, and the battery on Morris Island. On December 27, an assault force of 150 men seized the Union-occupied Castle Pinckney fortification, in the harbor close to downtown Charleston, capturing 24 guns and mortars without bloodshed. On December 30, the Federal arsenal in Charleston was captured, resulting in the acquisition of more than 22,000 weapons by the militia. The Confederates promptly made repairs at Fort Moultrie and dozens of new batteries and defense positions were constructed throughout the Charleston harbor area, including an unusual floating battery, and armed with weapons captured from the arsenal.
President Buchanan was surprised and dismayed at Anderson's move to Sumter, unaware of the authorization Anderson had received. Nevertheless, he refused Pickens's demand to evacuate Charleston harbor. Since the garrison's supplies were limited, Buchanan authorized a relief expedition of supplies, small arms, and 200 soldiers. The original intent was to send the Navy sloop-of-war USS Brooklyn, but it was discovered that Confederates had sunk some derelict ships to block the shipping channel into Charleston and there was concern that Brooklyn had too deep a draft to negotiate the obstacles. Instead, it seemed prudent to send an unarmed civilian merchant ship, Star of the West, which might be perceived as less provocative to the Confederates. As she approached the harbor entrance on January 9, 1861, Star of the West was fired upon by a battery on Morris Island, which was staffed by cadets from The Citadel, among them William Stewart Simkins, who were the only trained artillerists in the service of South Carolina at the time. Batteries from Fort Moultrie joined in and Star of the West was forced to withdraw. Major Anderson prepared his guns at Sumter when he heard the Confederate fire, but the secrecy of the operation had kept him unaware that a relief expedition was in progress and he chose not to start a general engagement.
In a letter delivered January 31, 1861, Governor Pickens demanded of President Buchanan that he surrender Fort Sumter because, "I regard that possession is not consistent with the dignity or safety of the State of South Carolina."
Preparations for war
Conditions at the fort were difficult during the winter of 1860–61. Rations were short and fuel for heat was limited. The garrison scrambled to complete the defenses as best they could. Fort Sumter was designed to mount 135 guns, operated by 650 officers and men, but construction had met with numerous delays for decades and budget cuts had left it only about 90 percent finished in early 1861. Anderson's garrison consisted of just 85 men, primarily made up of two small artillery companies: Company E, 1st U.S. Artillery, commanded by Capt. Abner Doubleday, and Company H, commanded by Capt. Truman Seymour. There were six other officers present: Surgeon Samuel W. Crawford, First Lt. Theodore Talbot of Company H, First Lt. Jefferson C. Davis of the 1st U.S. Artillery, and Second Lt. Norman J. Hall of Company H. Capt. John G. Foster and First Lt. George W. Snyder of the Corps of Engineers were responsible for construction of the Charleston forts, but they reported to their headquarters in Washington, not directly to Anderson. The remaining personnel were 68 noncommissioned officers and privates, eight musicians, and 43 noncombatant workmen.
By April the Union troops had positioned 60 guns, but they had insufficient men to operate them all. The fort consisted of three levels of enclosed gun positions, or casemates. The second level of casemates was unoccupied. The majority of the guns were on the first level of casemates, on the upper level (the parapet or barbette positions), and on the center parade field. Unfortunately for the defenders, the original mission of the fort—harbor defense—meant that it was designed so that the guns were primarily aimed at the Atlantic, with little capability of protecting from artillery fire from the surrounding land or from infantry conducting an amphibious assault.
In March, Brig. Gen. P.G.T. Beauregard took command of South Carolina forces in Charleston; on March 1, President Jefferson Davis had appointed him the first general officer in the armed forces of the new Confederacy, 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 low. He also increased drills amongst the South Carolina militia, training them to operate the guns they manned. Ironically, Major 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 March drilling and improving their fortifications to the best of their abilities.
Beauregard, a trained military engineer, built-up overwhelming strength to challenge Fort Sumter. Fort Moultrie had three 8-inch Columbiads, two 8-inch howitzers, five 32-pound smoothbores, and four 24-pounders. Outside of Moultrie were five 10-inch mortars, two 32-pounders, two 24-pounders, and a 9-inch Dahlgren smoothbore. The floating battery next to Fort Moultrie had two 42-pounders and two 32-pounders on a raft protected by iron shielding. Fort Johnson on James Island had one 24-pounder and four 10-inch mortars. At Cummings Point on Morris Island, the Confederates had emplaced seven 10-inch mortars, two 42-pounders, an English Blakely rifled cannon, and three 8-inch Columbiads, the latter in the so-called Iron Battery, protected by a wooden shield faced with iron bars. About 6,000 men were available to man the artillery and to assault the fort, if necessary, including the local militia, young boys and older men.
Decisions for war
On March 4, 1861, Abraham Lincoln was inaugurated as president. He was almost immediately confronted with the surprise information that Major Anderson was reporting that only six weeks of rations remained at Fort Sumter. A crisis similar to the one at Fort Sumter had emerged at Pensacola, Florida, where Confederates threatened another U.S. fortification—Fort Pickens. Lincoln and his new cabinet struggled with the decisions of whether to reinforce the forts, and how. They were also concerned about whether to take actions that might start open hostilities and which side would be perceived as the aggressor as a result. Similar discussions and concerns were occurring in the Confederacy.
After the formation of the Confederate States of America in early February, there was some debate among the secessionists whether the capture of the fort was rightly a matter for South Carolina or for the newly declared national government in Montgomery, Alabama. South Carolina Governor Pickens was among the states' rights advocates who felt that all property in Charleston harbor had reverted to South Carolina upon that state's secession as an independent commonwealth. This debate ran alongside another discussion about how aggressively the installations—including Forts Sumter and Pickens—should be obtained. President Davis, like his counterpart in Washington, 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; before 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.
The South sent delegations to Washington, D.C., and offered to pay for the Federal properties and enter into a peace treaty with the United States. Lincoln rejected any negotiations with the Confederate agents because he did not consider the Confederacy a legitimate nation and making any treaty with it would be tantamount to recognition of it as a sovereign government. However, Secretary of State William H. Seward, who wished to give up Sumter for political reasons—as a gesture of good will—engaged in unauthorized and indirect negotiations that failed.
On April 4, as the supply situation on Sumter became critical, President Lincoln ordered a relief expedition, to be commanded by former naval captain (and future Assistant Secretary of the Navy) Gustavus V. Fox, who had proposed a plan for nighttime landings of smaller vessels than the Star of the West. Fox's orders were to land at Sumter with supplies only, and if he was opposed by the Confederates, to respond with the U.S. Navy vessels following and to then land both supplies and men. This time, Maj. Anderson was informed of the impending expedition, although the arrival date was not revealed to him. On April 6, Lincoln notified Governor 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."
Lincoln's notification had been made to the governor of South Carolina, not the new Confederate government, which Lincoln did not recognize. Pickens consulted with Beauregard, the local Confederate commander. Soon Jefferson Davis ordered Beauregard to repeat the demand for Sumter's surrender, and if it did not, to reduce the fort before the relief expedition arrived. The Confederate cabinet, meeting in Montgomery, endorsed Davis's order on April 9. 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 only 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."
Beauregard dispatched aides—Col. James Chesnut, Col. James A. Chisholm, and Capt. Stephen D. Lee—to Fort Sumter on April 11 to issue the ultimatum. Anderson refused, although he reportedly commented, "I shall await the first shot, and if you do not batter us to pieces, we shall be starved out in a few days." The aides returned to Charleston and reported this comment to Beauregard. At 1 a.m. on April 12, the aides brought Anderson a message from Beauregard: "If you will state the time which you will evacuate Fort Sumter, and agree in the meantime that you will not use your guns against us unless ours shall be employed against Fort Sumter, we will abstain from opening fire upon you." After consulting with his senior officers, Maj. Anderson replied that he would evacuate Sumter by noon, April 15, unless he received new orders from his government or additional supplies. Col. Chesnut considered this reply to be too conditional and wrote a reply, which he handed to Anderson at 3:20 a.m.: "Sir: by authority of Brigadier General Beauregard, commanding the Provisional Forces of the Confederate States, we have the honor to notify you that he will open fire of his batteries on Fort Sumter in one hour from this time." Anderson escorted the officers back to their boat, shook hands with each one, and said "If we never meet in this world again, God grant that we may meet in the next." 
At 4:30 a.m. on April 12, 1861, Lt. Henry S. Farley, acting upon the command of Capt. George S. James, fired a single 10-inch mortar round from Fort Johnson. (James had offered the first shot to Roger Pryor, a noted Virginia secessionist, who declined, saying, "I could not fire the first gun of the war.") The shell exploded over Fort Sumter as a signal to open the general bombardment from 4003 guns and mortars at Fort Moultrie, Fort Johnson, the floating battery, and Cummings Point. Under orders from Beauregard, the guns fired in a counterclockwise sequence around the harbor, with 2 minutes between each shot; Beauregard wanted to conserve ammunition, which he calculated would last for only 48 hours. Edmund Ruffin, another noted Virginia secessionist, had traveled to Charleston to be present for the beginning of the war, and fired one of the first shots at Sumter after the signal round, a 64-pound shell from the Iron Battery at Cummings Point. The shelling of Fort Sumter from the batteries ringing the harbor awakened Charleston's residents (including diarist Mary Chesnut), who rushed out into the predawn darkness to watch the shells arc over the water and burst inside the fort.
Major Anderson held his fire, awaiting daylight. His troops reported for a call at 6 a.m. and then had breakfast. At 7 a.m., Capt. Abner Doubleday fired a shot at the Ironclad Battery at Cummings Point. He missed. Given the available manpower, Anderson could not take advantage of all of his 60 guns. He deliberately avoided using guns that were situated in the fort where casualties were most likely. The fort's best cannons were mounted on the uppermost of its three tiers—the barbette tier—where his troops were most exposed to incoming fire from overhead. The fort had been designed to withstand a naval assault, and naval warships of the time did not mount guns capable of elevating to shoot over the walls of the fort. However, the land-based cannons manned by the Confederates were capable of high-arcing ballistic trajectories and could therefore fire at parts of the fort that would have been out of naval guns' reach. Fort Sumter's garrison could only safely fire the 21 working guns on the lowest level, which themselves, because of the limited elevation allowed by their embrasures, were largely incapable of delivering fire with trajectories high enough to seriously threaten Fort Moultrie. Moreover, although the Federals had moved as many of their supplies to Fort Sumter as they could manage, the fort was quite low on ammunition, and was nearly out at the end of the 34-hour bombardment. A more immediate problem was the scarcity of cloth gunpowder cartridges or bags; only 700 were available at the beginning of the battle and workmen sewed frantically to create more, in some cases using socks from Anderson's personal wardrobe. Because of the shortages, Anderson reduced his firing to only six guns: two aimed at Cummings Point, two at Fort Moultrie, and two at the Sullivan's Island batteries.
Ships from Fox's relief expedition began to arrive on April 12. Although Fox himself arrived at 3 a.m. on his steamer Baltic, most of the rest of his fleet was delayed until 6 p.m., and one of the two warships, USS Powhatan, never did arrive. Unbeknownst to Fox, it had been ordered to the relief of Fort Pickens in Florida. As landing craft were sent toward the fort with supplies, the artillery fire deterred them and they pulled back. Fox decided to wait until after dark and for the arrival of his warships. The next day, heavy seas made it difficult to load the small boats with men and supplies and Fox was left with the hope that Anderson and his men could hold out until dark on April 13.
Although Sumter was a masonry fort, there were wooden buildings inside for barracks and officer quarters. The Confederates targeted these with Heated shot (cannonballs heated red hot in a furnace), starting fires that could prove more dangerous to the men than explosive artillery shells. At 7 p.m. on April 12, a rain shower extinguished the flames and at the same time the Union gunners stopped firing for the night. They slept fitfully, concerned about a potential infantry assault against the fort. During the darkness, the Confederates reduced their fire to four shots each hour. The following morning, the full bombardment resumed and the Confederates continued firing hot shot against the wooden buildings. By noon most of the wooden buildings in the fort and the main gate were on fire. The flames moved toward the main ammunition magazine, where 300 barrels of gunpowder were stored. The Union soldiers frantically tried to move the barrels to safety, but two-thirds were left when Anderson judged it was too dangerous and ordered the magazine doors closed. He ordered the remaining barrels thrown into the sea, but the tide kept floating them back together into groups, some of which were ignited by incoming artillery rounds. He also ordered his crews to redouble their efforts at firing, but the Confederates did the same, firing the hot shots almost exclusively. Many of the Confederate soldiers admired the courage and determination of the Yankees. When the fort had to pause its firing, the Confederates often cheered and applauded after the firing resumed and they shouted epithets at some of the nearby Union ships for failing to come to the fort's aid.

The fort's central flagpole was knocked down at 1 p.m. on April 13, raising doubts among the Confederates about whether the fort was ready to surrender. Col. Louis Wigfall, a former U.S. senator, had been observing the battle and decided that this indicated the fort had had enough punishment. He commandeered a small boat and proceeded from Morris Island, waving a white handkerchief from his sword, dodging incoming rounds from Sullivan's Island. Meeting with Major Anderson, he said, "You have defended your flag nobly, Sir. You have done all that it is possible to do, and General Beauregard wants to stop this fight. On what terms, Major Anderson, will you evacuate this fort?" Anderson was encouraged that Wigfall had said "evacuate," not "surrender." He was low on ammunition, fires were burning out of control, and his men were hungry and exhausted. Satisfied that they had defended their post with honor, enduring over 3,000 Confederate rounds without losing a man, Anderson agreed to a truce at 2 p.m.
Fort Sumter raised Wigfall's white handkerchief on its flagpole as Wigfall departed in his small boat back to Morris Island, where he was hailed as a hero. The handkerchief was spotted in Charleston and a delegation of officers representing Beauregard—Stephen D. Lee, Porcher Miles, a former mayor of Charleston, and Roger Pryor—sailed to Sumter, unaware of Wigfall's visit. Anderson was outraged when these officers disavowed Wigfall's authority, telling him that the former senator had not spoken with Beauregard for two days, and he threatened to resume firing. Meanwhile, General Beauregard himself had finally seen the handkerchief and sent a second set of officers, offering essentially the same terms that Wigfall had presented, so the agreement was reinstated.
The Union garrison surrendered the fort to Confederate personnel at 2:30 p.m., April 14. No one from either side was killed during the bombardment. During the 100-gun salute to the U.S. flag—Anderson's one condition for withdrawal—a pile of cartridges blew up from a spark, mortally wounding privates Daniel Hough and Edward Galloway, and seriously wounding the other four members of the gun crew; these were the first military fatalities of the war. The salute was stopped at fifty shots. Hough was buried in the Fort Sumter parade ground within two hours after the explosion. Galloway and Private George Fielding were sent to the hospital in Charleston, where Galloway died a few days later; Fielding was released after six weeks. The other wounded men and the remaining Union troops were placed aboard a Confederate steamer, the Isabel, where they spent the night and were transported the next morning to Fox's relief ship Baltic, resting outside the harbor bar.
Anderson carried the Fort Sumter Flag with him North, where it became a widely known symbol of the battle, and rallying point for supporters of the Union. This inspired Frederic Edwin Church to paint Our Banner in the Sky, described as a "symbolic landscape embodying the stars and stripes." A chromolithograph was then created and sold to benefit the families of Union soldiers.
The bombardment of Fort Sumter was the first military action of the American Civil War. Following the surrender, Northerners rallied behind Lincoln's call for all states to send troops to recapture the forts and preserve the Union. With the scale of the rebellion apparently small so far, Lincoln called for 75,000 volunteers for 90 days. Some Northern states filled their quotas quickly. There were so many volunteers in Ohio that within 16 days they could have met the full call for 75,000 men by themselves. Other governors from border states were undiplomatic in their responses. For example, Gov. Claiborne Jackson wrote, "Not one man will the state of Missouri furnish to carry on any such unholy crusade", and Gov. Beriah Magoffin wrote, "Kentucky will furnish no troops for the wicked purpose of subduing her sister Southern states." The governors of other states still in the Union were equally unsupportive. The call for 75,000 troops triggered four additional slave states to declare secessions and join the Confederacy. The ensuing war lasted four years, effectively ending in April 1865, with the surrender of General Robert E. Lee's Army of Northern Virginia.
Charleston Harbor was completely in Confederate hands for almost the entire four-year duration of the war, leaving a hole in the Union naval blockade. Union forces conducted major operations in 1862 and 1863 to capture Charleston, first overland on James Island (the Battle of Secessionville, June 1862), then by naval assault against Fort Sumter (the First Battle of Charleston Harbor, April 1863), then by seizing the Confederate artillery positions on Morris Island (beginning with the Second Battle of Fort Wagner, July 1863, and followed by a siege until September). After pounding Sumter to rubble with artillery fire, a final amphibious operation attempted to occupy it (the Second Battle of Fort Sumter, September 1863), but was repulsed and no further attempts were made. The Confederates evacuated Fort Sumter and Charleston in February 1865 as Union Maj. Gen. William T. Sherman outflanked the city in the Carolinas Campaign. On April 14, 1865, four years to the day after lowering the Fort Sumter Flag in surrender, Robert Anderson (by then a major general, although ill and in retired status) returned to the ruined fort to raise the flag he had lowered in 1861.
The U.S. Post Office Department released the Fort Sumter Centennial issue as the first in the series of five stamps marking the Civil War Centennial on April 12, 1961, at the Charleston post office.
The stamp was designed by Charles R. Chickering. It illustrates a seacoast gun from Fort Sumter aimed by an officer in a typical uniform of the time. The background features palmetto leaves akin to bursting shells. The state tree of South Carolina, the palmettos suggest the geopolitical area opening Civil War hostilities.
