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 Charles Dent
Dent's second book was "The Last Forty Years: Canada since the Union of 1841", which received praise. His third work was a "History of the Rebellion in Upper Canada" (1885–6). Through careful research, Dent was able to throw new light on the characters of the men who took part in the Upper Canada Rebellion. This work met with severe criticism when first published, as it contradicted commonly held beliefs at the time.
