U.S. troops and their Crow and Shoshone allies had engaged in battle with the Cheyenne and Lakota Sioux in what became known by Americans as the Battle of Rosebud Creek. Buffalo Calf Road Woman had ridden into battle with her husband, Black Coyote. As troops closed in on her brother, Chief Comes in Sight, Buffalo Calf Road Woman came to his rescue and saved his life. The incident was such a remarkable moment in Cheyenne history that they called it the Battle Where the Girl Saved Her Brother.
Following the Battle of Little Bighorn, the Northern Cheyenne were rounded up by U.S. troops and relocated to a reservation in Oklahoma. But a band of renegade Cheyenne, including Buffalo Calf Road Woman, Black Coyote and their two children, broke loose and headed back to Montana. En route, Black Coyote killed a Cheyenne chief, causing the family to be banished from the group. He also was involved in the death of a U.S. soldier in a separate incident.
