Lyon County's Fort Churchill was founded in July 1860 during the critical period of conflict between
Native Americans and newly arrived settlers. Captain Joseph Stewart, recently of Fort Alcatraz, had led forces from California to fight in the second phase of the
Pyramid Lake War. He then received orders to establish a fort to protect transcontinental trade and transportation routes as they extended through the western Great Basin. Stewart subsequently founded Fort Churchill on the north bank of the Carson River, to protect one of the more important lines of communication. The site was within easy reach of Carson City,
Dayton, and the newly developed
Comstock Mining District. While the garrison saw little action, it provided a federal presence during a critical period that included the Civil War.
