The Indian story of Custer’s last battle has never been told, except in a few fragmentary interviews that have been distorted into extravagant fiction. There were no white men survivors of that most thrilling of American frontier tragedies, so the veteran hostile red warriors have exclusive possession of the key to the mystery as to how it happened.

The present author, 61 years old and a resident of Montana throughout the past 41 years, decided in 1922 to apply himself at probing into this matter. He served a few months as agency physician for the Northern Cheyennes, a tribe allied with the Sioux in the annihilation of Custer. 

Since then, the investigator has been in close association with these Indians. He has learned the old-time plains Indian sign-talk to a degree, enabling him to dispense with interpreters, except in rare instances. He has held out continual invitation for Custer-battle veteran warriors to visit his home, partake of his food and smoke his tobacco. After a long siege, they began to come. Later, they began to talk, but only a little. Still later, after they had found out that this ingratiating white man was not scheming to entrap them into fatal admissions, they told the whole story.
