[Members of the Mormon Battalion were discharged at Los Angeles, Calif.] During the remainder of their enlistment, some members of the battalion were assigned to garrison duty at either San Diego, San Luis Rey, or Ciudad de los Angeles. Other soldiers were assigned to accompany General Kearny back to Fort Leavenworth. All soldiers, whether en route to the Salt Lake Valley via Pueblo or still in Los Angeles, were mustered out of the United States Army on 16 July 1847. Eighty-one men chose to reenlist and serve an additional eight months of military duty under Captain Daniel C. Davis in Company A of the Mormon Volunteers. The majority of the soldiers migrated to the Salt Lake Valley and were reunited with their pioneering families.
