Despite its lack of fortifications, Fort Kearny served as way station, sentinel post, supply depot, and message center for 49'ers bound for California and homeseekers traveling to California, Oregon and the Pacific Northwest. The earliest surviving photograph of the post, taken in 1858 by Samuel C. Mills, shows the post as a collection of adobe buildings without any wall or fortifications. By the 1860s the fort had become a significant state and freighting station and home station of the Pony Express. During the Indian Wars of 1864-1865 a small stockade was apparently built upon the earth embankment still visible. Although never under attack, the post did serve as an outfitting depot for several Indian campaigns.
