Battle of Round Mountain
- When
- 19 November 1861
- Where
- near the Round Mountains, exact site disputed; some accounts place the fight near Twin Mounds/Keystone
Confederate forces under Cooper encountered Opothleyahola's warriors near the Round Mountains on November 19, 1861, leading to a Confederate retreat.
Cooper's troops followed stragglers and blundered into Opothleyahola's warriors at the tree line at the foot of the Round Mountains. The physical location of the battle is in dispute; some accounts place the fight near Twin Mounds/Keystone rather than Yale, Oklahoma. Opothleyahola's forces drove the Confederates back to Fort Gibson. This was the first of three encounters between the opposing bands.
