The arrival of United States Army regiments in Montana Territory from 1866 to 1867, including companies from the 2nd Cavalry, 7th Infantry, First Battalion, 13th Infantry and Second Battalion, 18th Infantry (redesignated the 27th Infantry), relieved the need for a Territorial Militia, and after fighting no battles, the Montana Territory Volunteer Militia was disbanded by January 1868.
