With Great Britain embroiled in war with Napoleon’s France, the Royal Navy enforced a blockade aimed at choking France’s economy and neutral ships were not exempt from interception. This especially angered the United States who declared the blockade illegal and were increasingly concerned with American citizens finding themselves press-ganged into manning the blockade. Both American and British forces in Canada found themselves engaged in brief skirmishes such as one between between HMS Leopard and the USS Chesapeake in 1807 after the Leopard tried to board the American ship to search for British deserters.
On June 18th 1812, the 4th President of the United States, James Madison Jr, bowed to pressure from those in Congress who wanted war with Britain and signed the declaration. While it would last until February 18th 1815, the war is still remembered as the War of 1812. With the majority of British forces committed to fighting Napoleon in mainland Europe, the British had little choice but to initially adopt a defensive strategy against the Americans until they could bolster their numbers with troops from Europe and the enlistment of local native American tribes to carry out a guerrilla-style campaign against American troops.
On August 16th 1812, British Major General Henry Proctor succeeded in forcing the American contingent at Fort Detroit to surrender. This was a major concern for the Americans and so President Madison assigned General William Henry Harrison the task of retaking Fort Detroit during a winter offensive. Harrison split his army into two contingents. The first he commanded personally and marched his men to Upper Sandusky in modern-day Ohio.
The second contingent was led by Brigadier General James Winchester and consisted of 2,000 untrained regulars and volunteers mostly from Kentucky. As his men marched they were met by citizens of nearby Frenchtown which at that time was under occupation by a small British force from the Essex Militia and a native force from the Potawatomi tribe. Disobeying his orders to wait for Harrison and his men, Winchester ordered Lieutenant Colonel William Lewis to lead over 600 American troops to attack the British and their allies at their base across the frozen River Raisin.
Lewis attacked on January 18th and a brisk battle took place before the Americans forced the British and the Potawatomi to retreat. A Canadian militia group counterattacked later in the day but were unable to force Winchester back across the frozen river. During their retreat, the Potawatomi troops fell upon the settlement at Sandy Creek and destroyed it killing two of its inhabitants in the process.
Winchester was pleased with his victory although Harrison was concerned that his force was still outnumbered by British forces in the region. Upon hearing that Frenchtown had been taken, British Brigadier General Henry Procter marched 597 men from the 41st Regiment of Foot and Royal Newfoundland Fencibles along with around 800 native troops from the occupied Fort Detroit. Supported by Canadian artillery, Proctor’s men recaptured Frenchtown after a pitched battle on January 22nd.
The next day, a number of the captured American soldiers were massacred by native troops including a number of wounded soldiers who were burned to death inside the buildings where they were being kept. The native Americans then marched the survivors to Fort Malden in Ontario. Any American who couldn’t keep up was killed at the side of the road. The exact number of prisoners killed is not known but it is believed to be up to 100.
