The Battle of Claremore Mound, also known as the Battle of the Strawberry Moon or the Claremore Mound Massacre, was one of the chief battles of the war between the Osage and Cherokee Indians. It occurred in June, 1817, when a band of Western Cherokees and their allies under Chief Spring Frog (Too-an-tuh) attacked Pasuga, an Osage village at the foot of Claremore Mound (in present-day Rogers County, Oklahoma). During the two-day battle, the Cherokees killed or captured every member of Chief Clermont's band and destroyed everything they could not carry away. Historians consider it one of the bloodiest Native American massacres in modern history.
