Battle of Round Mountain

Tulsa County · Oklahoma
Erected by Oklahoma Historical Society, 1995

Where this fight happened is still argued. The Keystone site, now under Keystone Lake, was long accepted, but in 1949 researcher John H. Melton, with historians Berlin B. Chapman and Angie Debo, placed the battle four miles west of Yale in Payne County and called it Twin Mounds. The column moving north numbered nearly seventeen hundred: Upper Creek followers of Opothleyahola with Comanche, Delaware, Kickapoo, Seminole, Wichita and Shawnee Unionists, and enslaved people and Freedmen hoping to reach the north. Darkness and the danger of a prairie fire ended the fighting, and the column pushed on that night.
