Major [James] Denny with one hundred thirty convalescents and a corps of artillerists under Lieutenant Anderson was to hold possession of that part of Canada and afford all possible protection the well disposed inhabitants. A strong house belonging to one Gowris had stockaded and called Fort Gowris. In this and in a long stone building yet in Sandwich* which the American soldiers had used as barracks the convalescents were placed and Denny was ordered to defend the post... .
*This building was erected for a school in 1807 or 1808. It was in a dilapidated state when I sketched it in the autumn of 1860 It occupies an open space in the village of Sandwich. Several poor families occupied it. The place known as Spring Wells is opposite and indicated in our little sketch by the buildings with tall chimneys from which columns of smoke are rising. These compose the copper smelting works at Spring Wells.

From Ohio History:
1812, Aug. 12. Major James Denny evacuates the fortification at Gowles on the Canadian shore; the last American force left in Canada. A boat with a flag of truce is sent from Detroit to Sandwich, the head- quarters of General Isaac Brock. Hull denies that he sent the flag. At this juncture the colonels of the Ohio Volunteers and General J. Taylor of Kentucky counsel together and suspect the abilities and fidelity of General Hull. A letter is sent to Gov. Return J. Meigs by Lewis Cass asking that reinforcements be sent, which letter is endorsed by the colonels and General Taylor.
