From the Loyalist Trails UELAC Newsletter, 2012 Archive, the story of a Canadian who wouldn't give aid and comfort to the enemy (in this case the Americans).
"Many people still mistakenly think that nothing much happened in Grimsby (which was then called The Forty) during the War of 1812."
"When the Americans passed through The Forty...they stopped...and forced [George] Pettit to shoe their horses. Pettit...was hostile toward the enemy troops, so he trimmed the American horses' hoofs badly so that they were lamed. The angry Americans took Petitt prisoner.... ."
Note: My Howard ancestors were living in Grimsby before 1820; it is unknown whether any of them were living there during the War of 1812.
