Capt. John Allen dies at Fort Leavenworth. Overriding Allen's prior agreement with Brigham Young that the battalion's own officers would assume command in the event of his death, the Army appoints Lt. A.J. Smith, not a Latter-day Saint and destined to become unpopular among the men of the battalion, to be the unit's acting commander.
