Young-Man-Afraid-of-his-Horses 'Tasunka Kokipapi' (c.. 1830-1900). Although the hereditary Oglalachief, Man-Afraid yielded his tribal authority to Red Cloud amid the turbulent years when the Sioux and Cheyenne openly opposed the Boreman Trail and succeeded in their struggle to drive the army from Sioux hunting grounds within the Powder River country. He led his people on the warpath throughout the Red Cloud War and during his later years was president of the Pine Ridge Council and represented the Oglala in Washington on several occasions.
