Isaac Brock

Major-General Sir Isaac Brock KB (6 October 1769 – 13 October 1812) was a British Army officer and colonial administrator from Guernsey. He is best remembered for his victory at the siege of Detroit and his death at the Battle of Queenston Heights during the War of 1812.

Brock joined the army as a ensign in 1785. By 1797, he was a lieutenant colonel with the 49th Regiment of Foot. The regiment participated in the Anglo-Russian invasion of Holland in 1799 and in the 1801 naval expedition against Copenhagen. In 1802, the 49th Regiment was assigned to garrison duty in British North America. Despite facing desertions and near-mutinies, Brock successfully commanded his regiment in Upper Canada (part of present-day Ontario) for several years. He was promoted to colonel in 1805 and appointed brigadier general in 1808. In 1811 he was promoted to major general and given responsibility for defending Upper Canada against the threat of an American invasion. While many in Canada and Britain believed war could be averted, Brock began to ready the regulars and militia for what was to come. When the War of 1812 broke out, the populace was prepared, and quick victories at Fort Mackinac and Detroit temporarily thwarted American invasion attempts.

Brock's actions, particularly his success at Detroit, earned him accolades including a knighthood in the Order of the Bath and the sobriquet "The Hero of Upper Canada". His name is often linked with that of the Indigenous leader Tecumseh, although the two men collaborated in person only for a few days.

On October 13, 1812, the Americans crossed the Niagara River at Queenston and in the opening stages of the Battle of Queenston Heights captured a British artillery position on the high ground south of the village. Brock was shot and killed by an American sniper while leading a detachment of regulars and militia in an unsuccessful counterattack. Several hours later, British reinforcements from Niagara and Chippewa under Major General Roger Hale Sheaffe forced an American surrender.

Brock was born at St Peter Port on the Channel Island of Guernsey. He was the eighth son of John Brock (1729–1777), a former midshipman in the Royal Navy. His mother was Elizabeth de Lisle, the daughter of Daniel de Lisle, the lieutenant-bailiff of Guernsey. The Brocks were an English family who had been established in Guernsey since the sixteenth century. Brock earned a reputation during his early education on Guernsey as an assiduous student, as well as an exceptional swimmer and boxer. At age eleven, he was sent to school in Southampton, and afterwards to Rotterdam where he became fluent in French.

Although his formal education ended when he was a teenager, Brock appreciated its importance. As an adult, he spent much time reading in order to broaden his knowledge. He read many works on military tactics and science, but also read ancient history and other less practical topics. At the time of his death, he owned a modest library of books, including classic works by Shakespeare, Voltaire, and Samuel Johnson.

Brock kept his reputation as an "unusually tall, robust" man throughout his life, with an adult height of about 6 ft 2 in (188 cm). Measurements taken from his uniform show that at his death he had a waist size of 47 inches (120 cm), while the inside brim of his hat measured 24 inches (61 cm) in circumference. Although Brock was noted as a handsome man who enjoyed the company of women, he never married.

Brock had a successful pre-war military career and a quick rise through the ranks, which many commented on at the time. Some credited luck, and others skill, in his rapid promotions. Brock had substantial portions of both on his way to prominence. Lacking special political connections, his ability to gain promotions even when Britain was at peace attests to his ambition, and his skills in recruiting men and organizing finances.
