The War of 1812: Kingston and the St. Lawrence - Page Banner

Table of Contents

Letter While the fiercest battles in Upper Canada took place in the Niagara Peninsula, Kingston and the St. Lawrence region was not spared battles, raids and alarms.

The St. Lawrence River was the key to holding or capturing Upper Canada. All supplies moved up the river to the posts at Kingston and beyond. To cut this line would have resulted sooner or later in the fall of the province.
