Life in Missouri (1838–39)

By 1838, Smith had abandoned plans to redeem Zion in Jackson County, and instead declared the town of Far West, Missouri, in Caldwell County, as the new "Zion". In Missouri, the church also took the name "Church of Jesus Christ of Latter Day Saints", and construction began on a new temple. In the weeks and months after Smith and Rigdon arrived at Far West, thousands of Latter Day Saints followed them from Kirtland. Smith encouraged the settlement of land outside Caldwell County, instituting a settlement in Adam-ondi-Ahman, in Daviess County.

Political and religious differences between old Missourians and newly arriving Latter Day Saint settlers provoked tensions between the two groups, much as they had in Jackson County. By this time, Smith's experiences with mob violence led him to believe that his faith's survival required greater militancy against anti-Mormons. Tensions between the Mormons and the native Missourians escalated quickly until, on August 6, 1838, non-Mormons in Gallatin, Missouri, tried to prevent Mormons from voting, and a brawl ensued. The election day scuffles initiated the 1838 Mormon War. Non-Mormon vigilantes raided and burned Mormon farms, while Danites and other Mormons pillaged non-Mormon towns. In the Battle of Crooked River, a group of Mormons attacked the Missouri state militia, mistakenly believing them to be anti-Mormon vigilantes. Governor Lilburn Boggs then ordered that the Mormons be "exterminated or driven from the state". On October 30, a party of Missourians surprised and killed seventeen Mormons in the Haun's Mill massacre.

The following day, the Mormons surrendered to 2,500 state troops and agreed to forfeit their property and leave the state. Smith was immediately brought before a military court, accused of treason, and sentenced to be executed the next morning, but Alexander Doniphan, who was Smith's former attorney and a brigadier general in the Missouri militia, refused to carry out the order. Smith was then sent to a state court for a preliminary hearing, where several of his former allies testified against him. Smith and five others, including Rigdon, were charged with treason, and transferred to the jail at Liberty, Missouri, to await trial.

Smith bore his imprisonment stoically. Understanding that he was effectively on trial before his own people, many of whom considered him a fallen prophet, he wrote a personal defense and an apology for the activities of his followers. "The keys of the kingdom ", he wrote, "have not been taken away from us". Though he directed his followers to collect and publish their stories of persecution, he also urged them to moderate their antagonism toward non-Mormons. On April 6, 1839, after a grand jury hearing in Daviess County, Smith and his companions escaped custody, almost certainly with the connivance of the sheriff and guards.
