 Ten Bears was a key-figure in making peace between the Comanches and the Utes in 1820, and, after that, he lived for some years with the Utes, relatives to his stepmother.In the 1830s, Ten Bears was often in rivalry with a man named either "Isakwahip" 'Wolf's Back', or "Isakiip" 'Wolf's Elbow', leader of another local group in the North Canadian valley.In 1840 the Yamparika chief, Ten Bears, was one among the principal promoters (together with the Kiowa chiefs Dohasan and Satank and the Arapaho Hosa "Little Raven") of the peace and large alliance between the Comanche and Kiowa alliance and the Cheyenne and Arapaho alliance after the Cheyenne and Arapaho's victory at Wolf Creek during the spring 1838.
