Isa Tai was the medicine man of the band that came to Adobe Walls, if I’m remembering correctly. Dixon’s shot pretty much ended the battle, as the Comanche band didn’t have much faith in the medicine of Isa Tai to begin with. They didn’t stick around to take more casualties.

If you’re interested in Comanches, this book is my favorite.
