He was born around 1803 and died November 27, 1868.

In those sixty-five years he watched everything change around him — the gold rush that transformed Colorado from Cheyenne country to American territory, the treaty system that promised one thing and delivered another, the congressional investigation that condemned Sand Creek in official language but produced no prosecution, the Medicine Lodge council where he made his last major diplomatic effort, and the winter of 1868 when he returned from Fort Cobb without the protection he had sought and three days later was dead.

His wife Medicine Woman Later died with him.

She had survived nine bullet wounds at Sand Creek.
