The Battle of Chusto-Talasah was fought in Indian Territory [near todays Tulsa County, Oklahoma] on December 9th 1861.
The Battle of Chusto-Talasah was a part of series of battles fought between the Union leaning Creek and Seminole Indians against the Confederate leaning Cherokee and Choctaw Indians. Creek chief Opothleyahola leading his Union force was defeated at Round Mountain and retreated with his band to the northeast. They were located at Chusto-Talasah [also called the Horseshoe Bend of Bird Creek] on December 9th 1861 when they were attacked in the afternoon by about 1,300 Confederates led by Colonel Douglas H Cooper.
Opothleyahola had his troops placed in a strong line in heavy timber. They held their line for four hours as Cooper attacked and tried to outflank the Union soldiers. Finally just before dark Cooper’s men drove Opothleyahola force across the Bird Creek. Cooper was short on ammo and did not pursue the Union force.
Opothleyahola moved his band off, having lost about 400 men. Cooper counted only 52 casualties in the fight.
