CIVIL WAR
Fort Sumter: The 34 Hours That Made War Unavoidable
A hungry federal garrison, a calculated relief mission, and an artillery barrage in Charleston Harbor turned a secession crisis into open conflict.
Fort Sumter fell after 34 hours under Confederate fire in April 1861. The battle caused no combat deaths, but it brought a secession crisis into open war.
On the night of December 26, 1860, Major Robert Anderson moved his federal command from Fort Moultrie across Charleston Harbor to Fort Sumter. South Carolina had declared its secession six days earlier and demanded control of the harbor’s federal forts. Anderson considered Fort Moultrie too exposed on its landward side. Sumter offered a stronger position, but it was unfinished, incompletely armed, and short of food. [1]
The move did not resolve the crisis. It put a U.S. garrison inside a state claiming it had left the Union. For more than three months, Fort Sumter became a test of what secession would mean in practice.
A Garrison Under Pressure
Anderson commanded fewer than 90 soldiers, along with civilian workmen, in a fort encircled by South Carolina forces. Moving to Sumter made an immediate seizure less likely, but it did not solve the garrison’s supply problem. [1]
An earlier effort to provision the fort had already failed. On January 9, South Carolina cadets on Morris Island fired on the unarmed merchant vessel *Star of the West* and turned it away. Access to Fort Sumter could no longer be treated as routine federal business. [3]
When Abraham Lincoln took office on March 4, Anderson’s men were running short of food. Abandoning the fort would leave the federal post in Confederate hands. Sending armed reinforcements risked an immediate clash. Lincoln instead chose a narrower course: an expedition carrying provisions.
The Decision Over Supplies
Lincoln’s instructions called for food, not additional troops or ammunition, unless the expedition came under attack. On April 6, Governor Francis W. Pickens of South Carolina received notice that provisions would be sent to Fort Sumter. [1][3][4]
The notice left Confederate leaders with a direct choice. They could permit the resupply effort, or they could use force against the fort before it arrived.
Jefferson Davis’s administration ordered Brigadier General P.G.T. Beauregard, who commanded Confederate forces around Charleston, to obtain the fort’s surrender. On April 11, Beauregard’s representatives delivered a final demand to Anderson. He refused. [1]
The Barrage Began Before Dawn
At 4:30 a.m. on April 12, a mortar shell from Fort Johnson signaled the start of the Confederate bombardment. Batteries around Charleston Harbor fired on Fort Sumter, and Anderson’s garrison returned fire. [1]
The barrage continued for about 34 hours. Confederate forces fired more than 3,000 rounds toward the fort. Heated shot set the wooden barracks ablaze, and the fire threatened the garrison’s powder supply. [1][5]
The fort’s masonry was damaged, its interior buildings burned, and the men inside faced smoke, exhaustion, and dwindling ammunition. Yet no soldier on either side was killed during the bombardment itself. [5]
On the afternoon of April 13, Anderson accepted surrender terms. In his telegram reporting the result, he stated that he had agreed to evacuate after 34 hours of shelling. [2] The following day, the garrison lowered the flag and left Fort Sumter aboard transport ships bound for New York.
Two Union soldiers died on April 14 during a planned 100-gun salute as the garrison departed, when gunpowder exploded prematurely. Their deaths came after the artillery exchange, not during it. [5]
From Harbor Standoff to National Conflict
The fort’s fall gave Lincoln an event around which to call for national action. On April 15, he requested 75,000 state militia volunteers to suppress the rebellion. [3] The troop call reshaped the choices facing slaveholding states that had not yet seceded.
Virginia seceded two days later. Arkansas, North Carolina, and Tennessee followed after Lincoln’s call for troops. Their departure expanded the Confederacy and widened the conflict beyond Charleston Harbor. [3]
Fort Sumter remained in Confederate hands until Confederate forces evacuated Charleston on February 17, 1865. On April 14, 1865, Anderson returned to raise the U.S. flag over the fort again. [6]
The attack on Fort Sumter did not settle the questions that had brought the country to the brink. It did end the immediate standoff. After April 1861, both sides were mobilizing soldiers for war.
