The 5th Massachusetts Regiment also known as the 19th Continental Regiment was raised on April 17, 1775, under Colonel Mansfield outside of Boston, Massachusetts. The regiment saw action at the Battle of Concord, the Battle of Bunker Hill, the New York Campaign, the Battle of Trenton, and the Battle of Princeton. Colonel Rufus Putnam took command in January 1777 and participated in the Battle of Saratoga. The regiment was commanded by Colonel John Mansfield, of Lynn, who left the service on September 15, 1775 - after a court martial for failing to take the unit across the neck to support units on the Charlestown peninsula during the Battle of Bunker Hill. From then until the end of the year the regiment was commanded by Lieutenant Colonel Israel Hutchinson, of Danvers. It served in the siege of Boston, and afterwards was designated the 27th Continental Regiment in the 1776 establishment.
