Crook’s trained infantry and cavalry struggled to bring their discipline to bear on an enemy that wouldn’t stand still long enough to be engaged on conventional terms.

Somewhere in the middle of this battle, Comes in Sight rode out too far.

The specifics vary depending on which account you read.

In some versions, his horse was shot and fell beneath him, leaving him on foot in the middle of an open space between the lines.

In others, he made a bold charge — a coup ride, a display of courage meant to earn honor — that left him exposed.

In the Cheyenne oral tradition as it has been recorded, he was in a vulnerable position, surrounded by soldiers, in imminent danger of being killed.

What happened next is not disputed by any account that touches on it.

A rider appeared.

Coming fast across the exposed ground, heading straight toward the soldiers, straight toward the guns that were firing.

It was Buffalo Calf Road Woman.
