Lower Canada Rebellion
When news of the arrest of the Patriote leaders reached Upper Canada, William Lyon Mackenzie launched an armed rebellion in December 1837. In the meantime, filibusters from the United States, the Hunter Patriots, formed a small militia and attacked Windsor, Upper Canada, to support the Canadian Patriots. This resulted in the declaration of martial law by the Lower Canadian government.
John Lambton, 1st Earl of Durham
Lord Durham first set foot on the soil of British North America in Lower Canada on 29 May 1838. One of his tasks as Governor-General was to investigate the circumstances surrounding the Lower Canada Rebellion of Louis-Joseph Papineau and the Upper Canada Rebellion of William Lyon Mackenzie, which had both occurred earlier that year. His decisions with regard to the Rebellion prisoners encountered stiff opposition at Westminster, and he lost the support of the Prime Minister, Melbourne, whereupon he published his repudiation and resignation 9 October 1838 and set sail for London on 1 November.
