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.
Archibald McLean (judge)
He was named colonel in the militia during the Upper Canada Rebellion and commanded the left flank of the loyalist forces under Colonel James FitzGibbon at the Battle of Montgomery's Tavern. McLean initially opposed the Union of Upper and Lower Canada out of fear that Upper Canadians would be dominated by French Canadians. He saw responsible government as a danger to the British connection and to the ordered freedom and the recognition of class and property of the British tradition, but he quickly adjusted to the new reality.
