Cartier took part in the Battle of Saint-Denis, the Patriotes’ only military victory.
When the rebellion was eventually crushed, he went into hiding in the countryside, and then into exile across the border in the United States.
Their failed relationship was due, at least in part, to Cartier’s chronic womanizing.
After her husband’s death in London, Lady Cartier never again set foot in Canada.
Cartier was short in stature and elegant in bearing.
His clothing, hair, and manners projected the air of a gentleman, which is perhaps explained by the fact that he was unapologetically anglophile.
From then on, Cartier advocated compromise with the governing authorities, a point of view opposed to that which Louis-Joseph Papineau, the leader of the Patriote movement, continued to defend.
Cartier left the family home when he was just ten to attend the Collège de Montréal boarding school, known for its rigorous curriculum.
His convictions included adherence to the principles of responsible government and the parliamentary system.
In Cartier’s view, the premier or prime minister and his cabinet had to bear collective responsibility to the legislative assembly for decisions made by the executive.
After completing his secondary education, he studied law under Édouard-Étienne Rodier, who would become his mentor.
Rodier, a nationalist and an anticlerical who was sympathetic to the ideas of the Patriotes, considerably influenced the young Cartier’s political thinking, and probably his decision to join the Rebellion of 1837.
