These operations led to the expulsion of nearly all Mormons from the state following the issuance of Governor Lilburn Boggs' infamous Extermination Order in October of that year.

Peter Burnett, a lawyer from Ray County who would later become the first Governor of California, wrote that Bogart was "not a very discreet man, and his men were pretty much of the same character".

[1] During the fall of 1838, Bogart became involved in an ongoing dispute between members of the Church of Jesus Christ of Latter Day Saints, commonly known as "Mormons," and their non-Mormon neighbors in Daviess County.

However, the influx of new Mormon converts into Missouri caused them to start settling in adjacent counties (including Daviess), which many older settlers felt they had no right to do.

[7] However, Bogart and his men decided that the defensive posture ordered by Atchison was not to their liking, and so they divided into smaller units and proceeded to disarm Mormons living first in northern Ray County, then in southern Caldwell, as well.

[9] Nevertheless, lurid reports of alleged depredations by Bogart, who was already known for his vehemently anti-Mormon stance, were readily believed by Mormon leaders and historians.

[12] The Mormons rescued their hostages and drove Bogart from the field; however, when exaggerated accounts of the battle reached Missouri governor Lilburn Boggs (a notorious anti-Mormon), the governor responded by issuing his infamous "Extermination Order," which directed that the Mormons be "exterminated, or driven from the state"; the State Guard was directed to carry out this order.

During the subsequent preliminary hearing before Judge Austin King of Ray County, Bogart and his men were detailed to guard Joseph Smith and other high-ranking Mormon prisoners, as well as those witnesses assembled to testify in their behalf.

[15] Later, after the Mormons and their leaders (who had been permitted to escape from custody) had relocated to Nauvoo, Illinois, Bogart wrote a letter to the postmaster at nearby Quincy, Illinois; he described the Crooked River battle, and named nine alleged participants whom he asked the postmaster's help in locating and apprehending, together with property he claimed the Mormons had stolen from him.
