The Marblehead militia was formally adopted as a regiment of the Continental Army in Cambridge, Massachusetts, on June 22, 1775, with 10 companies totalling 505 officers and men. On July 1, Glover received a colonel's commission from the Continental Congress and the unit was designated the 23rd Massachusetts Regiment. In mid-December, Glover's regiment left Cambridge and returned to Marblehead and Beverly at the end of their terms of enlistment. The unit was reorganized as the 14th Continental Regiment on January 1, 1776.
