AI Summary

5 min read

In the summer of 1857, the U.S. government finally did what Jim Bridger had been asking for four years: it sent the army to Utah. Brigham Young’s theocracy had controlled nearly everything in Utah Territory since 1850, and tensions between Bridger and the Mormons had been building for years. In August 1853, a Mormon judge issued an arrest warrant for Bridger, charging him with treason for allegedly selling guns to Indians who used them to kill Mormons. Mormons effectively took over his trading post, Fort Bridger, and forced him to leave. Bridger complained to officials in Washington, including Secretary of War Jefferson Davis, but they claimed they could do nothing. He and his business partner eventually sold the fort to the Mormons for a fraction of its value and settled in Missouri.

By 1857, President James Buchanan had had enough of the clashes between Brigham Young’s theocracy and federally appointed officials over court jurisdiction, polygamy, and who held authority in the territory. He appointed a new governor and ordered 2,500 soldiers under Colonel Albert Sidney Johnston to escort him to Salt Lake City and ensure Young relinquished power peacefully. It was the largest assembly of troops in the United States at that time, and the army hired Jim Bridger as its chief scout.

Show Notes

After the loss of his trading post, Jim Bridger guides an army column to Utah Territory to confront Brigham Young and the Mormons. Bridger leads a frustrating expedition to the Yellowstone region, and then guides the U.S. Army to northern Wyoming as it attempts to build forts along the Bozeman Trail.
