Joseph Smith orders all Mormon troops at Far West and Diahman, Missouri, to surrender to state authorities. This officially ends the 1838 Mormon War in Missouri. Over the course of the Mormon War 22 people have been killed in the fighting and an unknown number have died due to sickness and exposure as a consequence of being expelled from their homes.
The final battle occurs at Far West, Missouri, where the Mormons are surrounded by government troops. According to some Latter Day Saint witnesses, Joseph Smith instructs Colonel George M. Hinkle, leader of the Mormon militia in Caldwell County, to "beg like a dog for peace" from Major General Samuel D. Lucas.
The terms are that every Mormon who has taken up arms must help pay for the damages they caused as well as the costs of calling up the state militia needed to stop them. Mormons must all surrender all of their arms to ensure that this doesn't happen again. Finally, all Mormons who participated in the fighting will be expelled from the state of Missouri, never to return.
Joseph Smith and the other Mormon leaders are promptly arrested so they can stand trial on charges of treason, murder, arson, burglary, robbery, larceny and perjury.
