The Aroostook War was an undeclared, bloodless conflict in 1839 that grew from a long-running boundary dispute left unsettled after the 1783 peace treaty ending the American Revolution. The disagreement between New Brunswick and what is now Maine intensified after Maine became a state in 1820 and began granting land in the Aroostook River valley despite British claims. After the U.S. Senate rejected in 1832 an arbitration award by the king of the Netherlands that Britain had accepted, tensions rose further. In the winter of 1838-1839, Canadian lumberjacks entered the Aroostook region to cut timber, and in February they seized the American land agent sent to expel them. Maine and New Brunswick then called out their militias, the U.S. Congress authorized a force of 50,000 men and appropriated $10 million, and Maine sent 10,000 troops to the disputed area. President Martin Van Buren sent General Winfield Scott, who arranged a March 1839 agreement between Maine and New Brunswick officials that prevented fighting. Britain then agreed to submit the issue to a boundary commission, and the dispute was settled in 1842 by the Webster-Asburton Treaty, under which Daniel Webster and 1st Baron Ashburton divided the territory by awarding 7,015 square miles to the United States and 5,012 to Great Britain, while preserving British year-round overland military communications with Montreal; Webster also used a map said to have been marked by Benjamin Franklin in Paris in 1782 to help persuade Maine and Massachusetts to accept the settlement, and Britain agreed to pay those states $150,000 each while the United States agreed to reimburse Britain for defense expenses in the area.
