Unattached Companies Massachusetts Volunteer Militia

The Unattached Companies of Massachusetts Volunteer Militia were units of infantry raised for the defenses of the eastern coast of Massachusetts during the American Civil War. Twenty-six companies were mustered into the Union Army during 1864-1865, several of them reorganizing for additional terms of service.

History

Beginning in April 1864, companies of infantry were needed for guard and garrison duty along the coast of Massachusetts; to be stationed at the numerous military posts located there for a ninety-day period. With the Independent Division of Militia, a home guard militia organization, already established in the state in 1863, eight companies were recruited from their ranks, and mustered into United States service. Five other companies were detached from existing regiments of the Massachusetts Militia to finish the required roster. Their term of enlistment soon ending, a call for 100-day companies was then ordered in July and August 1864 to fill the soon to be vacant positions at the coastal forts. Again, the state militia regiments were used to fill most of the quota, with a need to only recruit two new companies. In late October 1864, the office of the Adjutant General released orders to the commanding officers of the "Companies of One Hundred Days Troops belonging to Massachusetts, now doing garrison duty at the forts on the coast", to reenlist their commands for one year, and to fill with new recruits any positions held by those men not choosing to rejoin. Six of the 100-day companies were re-mustered, including the 2nd Unattached Company now beginning its third term. None of the one-year companies finished a full term, as the war had come to an end, and all were mustered out by July 1865.
