Fort Chadbourne Fort Chadbourne Fort Chadbourne was a fort established by the United States Army on October 28, 1852, in what is now Coke County, Texas, to protect the western frontier and the Butterfield Overland Mail route. It was named after Lt. T.L. Chadbourne, who was killed in the Battle of Resaca de la Palma. It was manned by Companies A and K of the 8th U.S. Infantry. During the early days of the American Civil War, the fort surrendered to the Confederates on February 28, 1861, even before the Confederate shelling of Fort Sumter, South Carolina, but was reoccupied by federal
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
