Wolf Voice (left) was a Gros Ventre by birth, who married Elk Woman, a Northern Cheyenne woman. He surrendered with the Cheyenne at Fort Keogh and afterwards scouted for General Miles in 1878/1879. He played a role as interpreter for Lt. Clark when Little Wolf was surrendering at Fort Keogh after his flight from Indian Territory. Christian Barthelmess later took pictures of him when he was a member of Lt. Casey´s Indian Scout force.

Standing right is Yellow Robe, who married a sister of Elk Woman. The white three-year-old child is Leo, Barthelmess´son. At this time (1889), Wolf Voice was an agency policeman. 

Casey Barthelmess, son of the photographer, recalled about Wolf Voice:

"I remember Wolf Voice, who was a Casey scout. Remember what Frederic Remington wrote about Wolf Voice? Said he had ´a grand face, tremendous physique and enough self-containment for a High-Church bishop´. I knew Yellow Robe, who was the last of the Cheyenne scouts to die. He passed away in 1957 in the Veterans Hospital at Miles
City."
