Treaty of Casco (1703) was an unsuccessful attempt made by Governor Joseph Dudley of Massachusetts Bay Colony to prevent further Indian hostilities from breaking out along the northern frontier.
Governor Dudley appointed a meeting of the several chiefs and their tribes to confer with him and his councilors to reconcile whatever differences had arisen since the last treaty.
[1] The Indians made the customary professions of peace, disavowing any conspiracy with the French to exterminate the English.
Vaudreuil was equally concerned about losing control of the Kennebec-Chaudiere river system, which led to Quebec City.
In August 1703, this force, accompanied by a band of Abenakis, raided the New England frontier from Casco to Wells, killing or taking prisoner some 160 people.
