Answer:
I was a prominent leader of the Southern Cheyenne during the American Indian Wars. Born to the Northern Só'taeo'o / Só'taétaneo'o band of the Northern Cheyenne in the Black Hills of present-day South Dakota, I later married into the Wotápio / Wutapai band of the Southern Cheyenne.
Explanation:
I became a chief in the 1850s and was a respected warrior and leader. As I grew older I realized that the on-rush of white settlers and the accompanying soldiers could not be stopped and peace was my tribe's best chance of survival. In 1861 I signed a peace treaty at Fort Wise in Colorado.
