Military Service Records of LDS Men 

This help section includes the history and records of several military operations in which Latter Day Saint members were directly involved from 1834-1848. Evidence that a Latter-day Saint actually served may be found in family traditions, census records, naturalization records, biographies, cemetery records, and records of veterans’ organizations. Your ancestors will be more interesting if you learn about their military service and the history of their units. Military records can also give birth dates, marriage dates, death dates, spouse and children’s names, and localities of residence throughout the life of the family.

Zion’s Camp (1834)

This Company was organized in Kirtland on the 7th of May, and as "Zion's Camp" took up their march westward, where they were to assist the persecuted saints in Missouri. They numbered 130 men, among whom were many leading elders. This little army was divided into companies of twelve men, each company choosing its own officer. By the time the camp reached Missouri its numbers had increased to 205. The following histories discuss this effort:

Mormon War in Missouri (1838)

The Mormon War is a name sometimes given to the 1838 conflict which occurred between Latter-day Saints (Mormons) and their neighbors in the northwestern region of the U.S. state of Missouri. The specific dates of the war are from August 6, 1838 (the Gallatin election battle) to November 1, 1838 when Joseph Smith surrendered at Far West. During the conflict 22 people were killed (3 Mormons and 1 non-Mormon at Crooked River and 18 Mormons at Haun’s Mill):

Nauvoo Legion and the Mormon War in Illinois (1840–1846)

In 1840 the Illinois Legislature authorized the Nauvoo City Council to establish a militia. The officers were commissioned by the governor, and the members were required to do the same amount of military duty as the regular state militia. In 1844 the Nauvoo Legion numbered about 5,000 men. The organization was disbanded in 1846, when the Mormon Battalion was created, and was reorganized in Utah in 1852. For a history see:

Mormon Battalion and the Mexican War (1846–1848)

In July 1846 the Mormon Battalion volunteers were officially organized at Council Bluffs, Iowa, to reinforce the United States Army in California during the Mexican War. The battalion consisted of five companies who enlisted for one year. Due to illness, about a third of the battalion did not complete the two-thousand-mile march but were sent to Pueblo, Colorado. The remaining members arrived in California in January 1847. They served in San Diego and Los Angeles. At the end of the one year, the army tried to reenlist all of the members, but only one company was organized in Los Angeles on 20 July 1847. This company only served for six months. After they were discharged, most battalion members went to Utah.
