Clay tells Colton a tale of Macgruder’s past. Turns out that Ned and Clay both served under MacGruder, who was a general during the war. However, he became obsessed with a buried Spanish treasure and murdered innocents, including natives and a priest. When Ned objected he was shot and left for dead. Though the war ended, MacGruder never stopped searching for this prize. Even now he builds up his power throughout the West in support of his search.
MacGruders men attack the camp and Colton was help fight them off. http://www.youtube.com/watch?v=IGELX234fEc
