Based on another Pony Express cover postmarked at St. Joseph on June 27, 1861, this Pony Express trip originated in San Francisco on June 15. Fort Bridger was a regular stop along the Pony route, and this cover was handed to the rider on June 20.
Fort Bridger was established in 1843 by famed mountain man Jim Bridger and a partner, Louis Vasquez, on Black's Fork of the Green River in the southwest corner of what is now Wyoming. It was for many years an important emigrant supply stop and Indian trading post along the Oregon Trail. In 1853 the Mormons took control of the fort after trying to arrest Bridger for selling gunpowder to the Indians -- this event led to a dispute over ownership that lasted many years. In 1857, with the outbreak of the Mormon War, the fort was abandoned and burned by the Mormons. In the summer of 1858, Fort Bridger was occupied by United States troops under the command of Albert Sydney Johnston, 2nd U.S. Cavalry. Fort Bridger postal markings from this early period carry the "U.T." Utah Territory designation. In 1861 most of the troops headed east to participate in the Civil War.
