Aroostook War

Aroostook War, a point of crisis in the Maine-New Brunswick boundary dispute which in early 1839 saw both sides send troops into the valley of the Aroostook, a tributary of the Saint John River. By the Treaty of Paris, 1783, the boundary was supposed to run north from the St Croix River to an undetermined height of land. At stake were the Acadian settlements of Madawaska, communication between the British provinces, and rich timber resources. Serious conflict was avoided through compromise and the dispute was resolved by the Webster-Ashburton Treaty of 1842.
