Massachusetts Line

The Massachusetts Line was the name given to those units within the Continental Army that were assigned to Massachusetts at various times by the Continental Congress during the American Revolutionary War. These, together with similar contingents from the other twelve states, formed the Continental Line. Line regiments were assigned to a particular state, which was then financially responsible for the maintenance (staffing and supplying) of the regiment. The concept of the line was also particularly important in relation to the promotion of commissioned officers. Officers of the Continental Army below the rank of brigadier general were ordinarily ineligible for promotion except in the line of their own state.

The size of the Massachusetts Line varied from as many as 27 active regiments (at the outset of the war) to four (at its end). For most of the war after the Siege of Boston (April 1775 to March 1776) almost all of these units were deployed outside Massachusetts, serving as far north as Quebec City, as far west as present-day central Upstate New York, and as far south as Yorktown, Virginia. Massachusetts line troops were involved in most of the war's major battles north of Chesapeake Bay, and were present at the decisive Siege of Yorktown in 1781. General officers of the line included Major Generals Artemas Ward, William Heath, and Benjamin Lincoln, and Brigadier Generals John Glover and John Nixon.

The line's history began in the immediate aftermath of the Battles of Lexington and Concord in April 1775, after which the Massachusetts Provincial Congress raised 27 regiments as a provincial army. These units, which were mostly organized by mid-May, were adopted into the first establishment of the Continental Army in June 1775. These units were generally referred to by the names of their colonels, and were numbered one way by the state and another by the Continental Army.
