A rare war-dated autograph letter by Patriot Samuel Adams to Major General Horatio Gates. This letter relates to Col. Henry Jackson's (1747-1809) Additional Continental Regiment (16th Massachusetts Regiment), then part of the Eastern Department, that General Gates oversaw. At the time of this letter, Jackson's Regiment was enroute from Falmouth, Maine back to Boston, after having assisted in the aftermath of the disastrous Penobscot Expedition--an expeditionary force assembled by Massachusetts that attempted and failed to reclaim the mid-coast of Maine. On August 28, Jackson wrote the Massachusetts Council, who ordered the Expedition, informing them of a possible attack on the town's port. He inquired whether he and his Regiment should defend it, and if so, requested appropriate munitions and provisions to be immediately sent. (Jackson to Massachusetts Council, August 28, 1779). After it was determined that no attack was imminent, Jackson's regiment of 400 troops was ordered to march back to Boston, leaving Falmouth on September 7.

Jackson's Regiment was raised in Boston in January 1777, and saw action in the Battles of Monmouth Courthouse and the Battle of Rhode Island. At the end of the 1779, they quartered in Morristown, New Jersey for the winter.
