The 1837 Rebellions in Upper and Lower Canada inspired American sympathizers to form the Hunter's Lodge, a secret organization originating among Lower Canadian refugees in Vermont. Led by figures such as William Lyon Mackenzie, Charles Duncombe, and Donald McLeod, the group sought to overthrow British colonial rule in Canada.
Between December 1837 and December 1838, Patriot raiders launched more than a dozen attacks across the Canada–United States border against the British colony of Upper Canada. A short-lived Republic of Canada was proclaimed on Navy Island but collapsed after British bombardment, forcing Mackenzie and his fighters to retreat to Buffalo, New York, where US forces captured them.
The United States and British governments allied to suppress the Patriot movement. Raiders captured in the US were convicted of violating neutrality laws and sentenced to 18 months in prison. Their dispersal required the largest deployment of US troops against American citizens since the Whiskey Rebellion of 1794, effectively ending the organized cross-border insurgency.
