Following Geronimo's escape from the San Carlos Reservation in Arizona, the United States Army began the Geronimo Campaign to capture the Apache leader who had fled into Mexico. It was during this operation that Captain Crawford, or the 3rd Cavalry, was ordered to proceed south from Fort Apache to pursue the natives. He took with him, just under 100 Apache scouts with Lieutenants Marion P. Maus, William Shipp and Samuel L. Faison. Among the party was the Apache Kid and three armed civilians, including the famous scout Tom Horn, a doctor named T. B. Davis, and Concepción, a translator who spoke Apache.
