Raid on Malcolm’s Mills

The Raid on Malcolm’s Mills on 6 November 1814 was the last American incursion into Upper Canada during the war. Brigadier General Duncan McArthur led approximately 700 mounted volunteers from Kentucky and Ohio on a sweeping raid through the interior of the province, destroying mills, supplies, and infrastructure before returning to Detroit. The raid inflicted economic damage but achieved nothing of strategic permanence.

McArthur’s column crossed into Upper Canada from Detroit and rode eastward through the Grand River valley, covering over 150 miles in Canadian territory. The raid was conducted after the American withdrawal from Fort Erie — the Niagara campaign was over — and its purpose was primarily punitive: to destroy the mills and granaries that supported British military operations in the region.

At Malcolm’s Mills, near present-day Oakland, Ontario, McArthur encountered a force of approximately 400 Norfolk and Oxford militia under Lieutenant Colonel Henry Bostwick. The militia were positioned behind the Grand River, but the mounted Americans found a ford upstream, crossed, and attacked from an unexpected direction. The engagement was brief. The militia, outnumbered and outflanked, broke after a short resistance. Eighteen were killed and approximately forty captured. McArthur’s losses were one killed.

The raiders destroyed several mills and quantities of grain before withdrawing back to Detroit. The destruction was significant for the local population, who depended on the mills for processing their harvest, but it did not affect the war’s outcome. The Treaty of Ghent was signed seven weeks later, and every acre of territory returned to its pre-war holder.

Malcolm’s Mills marked the end of American offensive operations in Upper Canada. In three years of war, the United States had launched invasion after invasion — through Detroit, across the Niagara, down the St. Lawrence, and into the interior. None had achieved a permanent foothold. The last American soldiers to enter Upper Canada were raiders who burned mills and rode home. The province that Jefferson had predicted would be conquered as “a mere matter of marching” remained as British as it had been in June 1812.
