Battle of Fort Sumter Battle of Fort Sumter The Battle of Fort Sumter (April 12–13, 1861) was the bombardment of Fort Sumter near Charleston, South Carolina by the Confederate States Army, and the return gunfire and subsequent surrender by the United States Army, that started the American Civil War. Following the declaration of secession by South Carolina on December 20, 1860, its authorities demanded that the U.S. Army abandon its facilities in Charleston Harbor. On December 26, Major Robert Anderson of the U.S. Army surreptitiously moved his small command from the vulnerable Fort Moultrie on Sullivan's Island to Fort Sumter, a substantial fortress built
Fort Washita west to protect the new frontier. The Army established Fort Cobb in October 1859. Many men who served at Fort Washita would go on to become famous, including Randolph B. Marcy, George McClellan, William G. Belknap and Theophilus H. Holmes. Federal troops still occupied Fort Washita when the Confederates fired on Fort Sumter on April 12, 1861. Expecting war Colonel William Emory had concentrated all of his Federal troops from Forts Arbuckle and Cobb at Fort Washita. When news of Fort Sumter reached Emory on April 16 he led his forces to Fort Leavenworth, Kansas, pursued by 4000 Texas militia
