the province of Massachusetts Bay in order to establish "so much of it as lies between the Sawkno [Saco] River and the St. Croix, which is the southeast boundary of Nova Scotia into a new province, which from its situation between the New England province and Nova Scotia, may with great propriety be called New Ireland". Pursuant to the terms of the 1783 Peace of Paris all British forces then evacuated Fort George (followed by some 600 Loyalists who removed from the area to St. Andrews on Passamaquoddy Bay) and abandoned their attempts to establish New Ireland. During the War of 1812, however, British forces again occupied Fort George (still calling the area New Ireland) from September 1814 to April 1815 and used it as a naval base before withdrawing again with the arrival of peace. Full ownership of present-day Maine (principally the northeastern borders with New Brunswick) remained disputed until the Webster-Ashburton Treaty in 1842. The "District of Maine" was a part of Massachusetts until 1820 when it was admitted into the Union as the 23rd state as part of the Missouri Compromise.

Evidence of scuttled ships was also found under the Joshua Chamberlain Bridge in Bangor and under the Bangor town dock, and several artifacts were recovered. Cannonballs were also reported to have been recovered during the construction of the concrete casements for the I-395 bridge in 1986. The earthworks of Fort George stand at the mouth of the Penobscot River in Castine, accompanied by concrete work added later by the Americans in the 19th century. Archaeological evidence of the expedition, including cannonballs and cannon, was located during an archaeological project in 2000–2001. Since 2004 a comprehensive exhibit on the Penobscot Expedition has been provided by the Castine Historical Society, located at its base on School Street, Castine. In 2021, San Francisco Unified School District announced that it would strip Paul Revere's name from Paul Revere K-8 for his role in the Penobscot Expedition. The San Francisco Board of Education mistakenly believed the expedition was to steal land from the Penobscot people. In popular culture Bernard Cornwell's 2010 historical novel The Fort gives an account of the expedition. It draws attention to the presence there of a junior
