Book excerpt: Few events in the history of the American Far West from 1846 to 1849 did not involve the Mormon Battalion. The Battalion participated in the United States conquest of California and in the discovery of gold, opened four major wagon trails, and carried the news of gold east to an eager American public. Yet, the battalion is little known beyond Mormon history. This first complete history of the wide-ranging army unit restores it to its central place in Western history, and provides descendants a complete roster of the Battalion's members.
