1812-1813: Invasion Repelled

In 1812, the United States invaded Canada.

In June 1812, the United States declared war on Britain, already locked in combat with Napoleon’s France. The resulting War of 1812 was fought largely on Canadian territory, especially along the Niagara frontier.

The Americans were superior in numbers but badly organized. First Peoples, including a Shawnee contingent led by Tecumseh, and Canadian militia units provided invaluable support to Canada’s garrison of professional soldiers. In October 1812, Sir Isaac Brock, commander-in- chief of Upper Canada, was killed defeating a major American invasion attempt at Queenston Heights, on the Niagara River. Much skirmishing and raiding occurred throughout the first part of 1813, especially along Lake Ontario and the Niagara frontier.
