General Sir John Coape Sherbrooke, was a British soldier and colonial administrator. After serving in the British army in Nova Scotia, the Netherlands, India, the Mediterranean, and Spain, he was appointed Lieutenant-Governor of Nova Scotia in 1811. During the War of 1812, his policies and victory in the conquest of present-day Maine, renaming it the colony of New Ireland, led to significant prosperity in Nova Scotia.

The Battle of Hampden was an action in the British campaign to conquer present-day Maine and remake it into the colony of New Ireland during the War of 1812. Sir John Sherbrooke led a British force from Halifax, Nova Scotia to establish New Ireland, which lasted until the end of the war, eight months later. The brief life of the colony yielded customs revenues which were subsequently used to finance a military library in Halifax and found Dalhousie College.
