Isaac Brock was a British major-general and administrator, who served in various parts of the Empire for nearly thirty years, serving in the Caribbean, Denmark, and elsewhere. During that time he challenged duelists, nearly died from fever, was injured in battle, faced both desertions and near mutinies, and also had the privilege of serving alongside Lord Nelson. However, he is best remembered for his actions while assigned to the Canadian colonies. Brock was assigned to Canada in 1802, eventually reaching the rank of Major-General. In this capacity, he was responsible for defending Canada from the United States during the War of 1812. While many in Canada and in England believed war could be averted, Brock began preparing the army, the militia, and the populace for what was to come. Thus, when war broke out, Canada was prepared, and quick victories at Fort Mackinac and in the Battle of Detroit crippled American invasion efforts, securing Brock's reputation as a brilliant leader and strategist. His death in the Battle of Queenston Heights was a crushing blow to British leadership. Brock's efforts earned him accolades, a knighthood, and the moniker "The Hero of Upper Canada".
