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.
Upper Canada Rebellion
Unlike previous Lt. Governors, Bond Head threw himself into the electoral fray in support of the Tory candidates, and utilized Orange Order violence in order to ensure their election. In the face of what was believed to be widespread fraud, William Lyon Mackenzie and Samuel Lount lost their seats in the Legislature. The reformers prepared a petition to the Crown protesting the abuses, carried to London by Charles Duncombe, but the Colonial Office refused to hear him. These three men became core organizers of the Rebellion.
