text_A: The British occupied the town of Castine and most of eastern Maine for the rest of the war, governing it under martial law and re-establishing the colony of New Ireland. The Treaty of Ghent returned this territory to the United States. When the British left in April 1815, they took £10,750 in tariff duties from Castine. This money, called the "Castine Fund", was used to establish Dalhousie University in Halifax. Decisions about the islands in Passamaquoddy Bay were decided by joint commission in 1817. However, Machias Seal Island had been seized by the British as part of the occupation and was unaddressed by the commission. While kept by Britain/Canada, it remains in dispute to this day.
text_B: Would Machias Seal Island be considered spoils of war for the British and Canadian side to this day?
YES.
