In 1838, Elizabeth was visiting friends in Clayton ( not Lanark County Clayton) when she overheard plans to attack Gananoque. She bravely crossed the frozen St. Lawrence River to warn the town. The town prepared with liquor, guns, men and horses scouting out the American’s progress. It was bitter cold but the ice was unreliable and some men and horses were lost. The scouts concentrated their efforts at Hickey Island, close to Grindstone and found there that the Americans abandoned their plans. Two towns full of friends were saved by a heroine.
