Black Kettle.

Cheyenne peace chief.

Survivor of Sand Creek.

Killed at the Washita.

The flags he raised should not have needed to be raised.

But he raised them, because he believed in the possibility of peace even after it had proved deadly.

He deserves to be remembered for what he was: one of the most courageous and principled leaders in the history of the southern plains.

A man who sought peace at the cost of his own safety and ultimately his life.
