Fort Sumter, situated in Charleston Harbor, South Carolina, became the flashpoint of the American Civil War for compelling strategic and symbolic reasons.
Charleston was the Confederacy's largest port and commercial hub. Cotton exports through this harbor financed the Southern war effort. Union blockade runners operating from Charleston imported weapons, medicine, and manufactured goods. Controlling Fort Sumter meant controlling this economic lifeline.
After a 34-hour bombardment, Major Robert Anderson surrendered the fort on April 13, 1861. The Confederacy held it until February 1865, when Sherman's advance forced evacuation. The fort's fall bookended the war - its surrender began the conflict; its recapture signaled the Confederacy's collapse.
Fort Sumter wasn't just a fort - it was the key to Charleston, the gateway to Southern independence, and the stage where the Civil War's curtain rose.
