"Territorial encroachments initiated by Maine on British lands in Aroostook culminated in 1839 with the menacing encampment of 10,000 Maine troops on British borders. General Winfield Scott was sent by the Federal Government to negotiate a truce with the Lieutenant Governor of New Brunswick. Great Britain, now convinced of the gravity of the situation, authorized a boundary commission headed by Mudge and Featherstonhaugh. Their findings were incorporated into the Webster-Ashburton Treaty (1842) which allowed for free navigation of the St. John River and rectified the boundaries at the head of the Connecticut River, the north end of Lake Champlain, in the Detroit River and at the head of Lake Superior" (Siebert).
