The surrender concluded a standoff that began with South Carolina's secession from the Union on December 20, 1860. When President Abraham Lincoln sent word to Charleston in early April that he planned to send food to the beleaguered garrison, the Confederates took action. They opened fire on Sumter in the predawn of April 12. Over the next day, nearly 4,000 rounds were hurled toward the black silhouette of Fort Sumter.
Inside Sumter was its commander, Major Robert Anderson, 9 officers, 68 enlisted men, 8 musicians, and 43 construction workers who were still putting the finishing touches on the fort. Union Captain Abner Doubleday, the man often inaccurately credited with inventing the game of baseball, returned fire nearly two hours after the barrage began. By the morning of April 13, the garrison in Sumter was in dire straits. The soldiers had sustained only minor injuries, but they could not hold out much longer. The fort was badly damaged, and the Confederate's shots were becoming more precise. Around noon, the flagstaff was shot away. Louis Wigfall, a former U.S. senator from Texas, rowed out without permission to see if the garrison was trying to surrender. Anderson decided that further resistance was futile, and he ran a white flag up a makeshift flagpole.
The first engagement of the war was over, and the only casualty had been a Confederate horse. The Union force was allowed to leave for the north; before leaving, the soldiers fired a 100-gun salute. During the salute, one soldier was killed and another mortally wounded by a prematurely exploding cartridge. The Civil War had officially begun.
