This area, then known as the Sequoyah District, was dominated by Cherokee who were Confederate sympathizers during the Civil War, as were the majority of the nation. Many of the Cherokee were slaveholders; they also had been told that the Confederates would provide them with a Native American state if victorious in the war. The only combat was on June 15, 1864, when Colonel Stand Watie and his Confederate troops conducted the ambush of the Union steamboat "J. R. Williams" on the Arkansas River.
