The Chief Who Wanted Peace And Died For It — The Tragic Story Of Black Kettle
This is not a comfortable framing, because it requires acknowledging both that he made the right choices and that those choices led to catastrophe.

He was a leader who made strategic choices based on genuine analysis, who maintained those choices with consistent courage, and who was killed because the people he was negotiating with did not honor their commitments.
That is the language that does him justice.
