A series of battles were fought in December in bad weather between the Confederate Cherokee and Choctaw Indians and the Union Creek and Seminole Indians (led by the Muscogee Creek chief Opothleyahola) who supported the Federal government. Following Opothleyahola and his Union force’s defeat at Round Mountain, he retreated northeastward in search of safety. On December 9, 1861, the force was at Chusto-Talasah (Caving Banks) on the Horseshoe Bend of Bird Creek when Col. Douglas H. Cooper’s 1,300 Confederates attacked about 2:00 p.m. Chief Opothleyahola knew Cooper was coming and had placed his troops in a strong position in heavy timber at Horseshoe Bend.
