In January 1863, Coloradas agreed to meet with U.S. military leaders at Fort McLane, near present-day Hurley in southwestern New Mexico. Coloradas arrived under a white flag of truce to meet with Brigadier General Joseph Rodman West, an officer of the California militia. Again the Americans violated the neutrality of the white flag. The armed soldiers took him into custody, and West is reported to ordered the sentries to execute the Apache leader. That night Mangas was tortured, shot and murdered, as he was "trying to escape." The following day, soldiers cut off his head, boiled it and sent the skull to the Smithsonian Institution. The mutilation of Coloradas' body increased the hostility of the Apache toward the United States.
