From Union Army soldier to teamster to Guernsey, Wyo., town father, John “Posey” Ryan earned a reputation as an honorable man. But his life’s path took a wrong turn when, believing they had stolen his livelihood, he publicly shot his wife and her daughter to death.

In 1854, a year of heavy traffic on the Oregon Trail, Fort Laramie was woefully undermanned, tribes were hungry and tensions were growing. That August, in a dispute over a strayed cow, a reckless young West Pointer ignited a war with the Lakota Sioux that would last a generation.

In August 1922, five U.S. Marines “invaded” the U.S. Naval Petroleum Reserve at Teapot Dome in central Wyoming to evict oil drillers the government had determined were there illegally. Bribery connected with acquiring those drilling rights eventually led to the Teapot Dome scandal—one of the worst in U.S. politics.

Moncreiffes, Wallops, Careys and other Wyoming dealers offered local stockmen high prices for tens of thousands of horses for British and French markets during the Boer War and World War I. After that war, the U.S. Army expanded its remount service to improve bloodlines for horses for military markets.

Mathew Campfield, African-American Union Army veteran, worked as a barber and was elected coroner of Natrona County, Wyo., in the early 1890s. Decades earlier, he froze both feet when he lived in Kansas and ever afterward walked on wooden ones. His Army pension records reveal a great deal about his life. 

Wyoming National Guard soldiers joined tens of thousands of others from around the nation near the Mexican border in 1916, after regular U.S. troops were sent to chase the revolutionary Pancho Villa and his forces into Mexico. None of the guardsmen saw action, but all received important training as World War I loomed.

After the Civil War, about one-fifth of the regular U.S. cavalry troops in the West were Black. These buffalo soldiers were sent to keep order on a disorderly frontier—a difficult job with blurry ethical boundaries. Despite meager food, castoff equipment and chronic racial prejudice, they performed well.

Seeking a shorter way to the goldfields of Montana Territory, former prospector John Bozeman traced a route through the Powder River Basin—prized buffalo grounds for the resident tribes. A few hundred emigrants used the route between 1863 and 1866; later, as tribal resistance grew, it became primarily a military road.

Two military posts were built a few miles apart during the Indian Wars near the strategic Bozeman Trail crossing of Powder River—Fort Reno in the 1860s and Cantonment Reno in the 1870s. The first was one of three forts whose existence provoked the tribes into war. The second was an important Army base for later campaigns.

Jim Bridger’s skills as guide, mapmaker and businessman were unmatched. After 20 years trapping beaver in the northern Rockies, he co-founded Fort Bridger in 1843. In the 1850s and 1860s he guided important government exploring expeditions and guided troops on Indian campaigns. In 1868 he retired to Missouri, where he died in 1881.
