The Apaches were particularly resistant to reservation life, and from 1881 to 1886, chief Geronimo led the Apaches in a series of raids on American settlers in the Southwest. In 1886, General George Crook tracked down Geronimo and his band at the Canyon de los Embudos in the Sierra Madre Mountains. The general persuaded the Apaches to meet with him in a conference which took place from March 25 to March 27. In the course of the negotiating, Crook convinced Geronimo to end the raids and agree to a conditional surrender, whereby the Apaches would accept reservation life if they could be reunited with their families who were being held prisoner in Florida. Soon after the conference Geronimo escaped, and Crook was replaced by General Nelson Miles. Geronimo is second from the left, Crook second from the right.
