1st Massachusetts Heavy Artillery Battalion

The 1st Battalion of Massachusetts Volunteer Heavy Artillery was a unit that served in the Union Army during the American Civil War.

It was organized from several unattached companies of heavy artillery already raised and mustered into a three-year service for the defenses of the Massachusetts coast.

They remained here until 24 December 1864, when ordered to Champlain, New York due to "trouble being feared on the Canadian border".

The 2nd Unattached Company was organized in October and November 1862, joining the 1st in garrison duty at Fort Warren.

Except where mentioned previously, the companies were all stationed at forts in Boston Harbor, with detachments from them being sent to other military locations along the coast.
