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 after the occupation had began, and while they argued that it should be unaddressed by the commission, a joint decision returned it to the United States. While kept by the US, it remains a matter of occasional dispute to this day.
text_B: If someone wanted to travel from Maine to Machias Seal Island for a visit, would they need a passport to do so?
NO.
