Kills in the Water (Hunkpapa) relates his impression of the Custer Fight to Col. A.B. Welch in 1941, Welch Dakota Papers, www.welchdakotapapers.com, with my annotations in brackets:
I was in six battles. That fight in Montana was one of them. At that fight the soldiers were scared; they fired their guns into the air; we rode over them and killed them with stone clubs. They attacked us; we killed them quickly.... There was one Sioux woman [fighting] in the Custer Battle. [Note: This was likely Mary Crawler, aka. Moving Robe Woman] No one knows who killed Custer. His soldiers shot into the air. We rode into them and killed them with war clubs. No one even knew Custer at the time. They were attacking us and we fought them.
