In Utah March 23rd 1858 Brigham Young ordered the faithful to move to Provo, Utah and prepare for their homes in Salt Lake City to be burned as part of his “Sebastopol Policy”
From 1857 to 1858 what is known as the Utah War occurred between the United States Government and the Mormon settlers in the Utah Territory. The election in 1856 between Democrat James Buchanan and Republican John C Freemont was close enough to shake the Democratic Party. The Republicans charged the Democrats during that election as being soft on the “Twin Relics of Barbarism”; polygamy and slavery. In order to stand up to the charge Buchanan had do something, he decided his only political option was to replace Brigham Young as the governor of the Utah Territory and make a stand against polygamy. Alfred Cumming was appointed the new governor and sent to Utah under an Army escort.
The first troops to march for Utah were lead by General William S Harney, but they were forced to return to Kansas. Then a detachment under Colonel Edmund Alexander got started, only to meet up with and give command to Colonel Albert Sidney Johnston. The Utah militia known as the Nauvoo Legion under the command of Lot Smith harassed the federals. Johnston decided to settle for the winter in the burned out Fort Bridger.
When spring arrived the United States Army was re-supplied and reinforcements arrived. With negotiation underway Brigham Young accepted the replacement governor; bring peace back to the territory.
