Sir Isaac Brock, military commander, administrator of Upper Canada (born 6 October 1769 in St Peter Port, Guernsey, England; died 13 October 1812 in Queenston Heights, Upper Canada). Major-General Sir Isaac Brock is best known for defending Upper Canada against American forces during the War of 1812. He is, in part, credited with defeating the Americans at Fort Mackinac and Detroit. He died in the Battle of Queenston Heights, but has been immortalized as a great hero of Upper Canada.
Early Life and Education
Isaac Brock was educated in Guernsey, Southampton (England) and Rotterdam. At age 15 he entered the army by buying a commission in the 8th (King's) Regiment of Foot. He transferred to the 49th Regiment in 1791 and soon after demonstrated his willingness to take a calculated risk.
Did You Know?
An officer in the 49th Regiment, who was both "a confirmed duelist" and a dead shot, challenged Brock. Being tall, Brock knew that he would present an easy target at the usual distance of 12 paces apart. As they prepared for the duel, he demanded that they meet on equal terms. For this purpose, he produced a handkerchief and insisted they fire at each other, not from the usual distance apart, but across the handkerchief. His antagonist declined and soon after left the regiment. Brock seemed to possess almost uncanny insight into what others – particularly opponents – were thinking and how they might respond to determined action.
Brock's military career advanced another step in 1797 when he bought a commission as lieutenant colonel and became the regiment's commanding officer. His brother, William, loaned him the money to buy commissions – a common practice in the British army of that time – and, later, when William went bankrupt, Brock was faced with the problem of paying off his debt.
Arrival in Canada and War of 1812
He arrived in Canada in 1802 with the 49th and was promoted to major general in 1811. With the forthcoming departure of Francis Gore, he was appointed president of the executive council of Upper Canada (administrator) and commander of the forces there.
Tecumseh and the Capture of Detroit
Major General William Hull had invaded Upper Canada in July, but withdrew to Fort Detroit upon learning that Brock was leading troops to that front. He arrived at Fort Amherstburg and knew from captured correspondence about serious dissension among Hull's officers and Hull's increasing fear of defeat.
Brock met Shawnee warrior Tecumseh and the two became firm allies. Brock decided to act quickly before Hull received reinforcements. On the night of 15-16 August, Tecumseh and his warriors crossed the Detroit River to be followed early the next morning by Brock and his troops. Brock's intention was to form up his troops and hope Hull would come out of his strong, well-armed fort to fight in the open. But, on hearing of American troops at his rear, Brock decided on immediate attack. He led his troops forward even though all they could see facing them as they approached were two 24-pounder guns, their gunners standing by with their matches burning.
Brock was urged to let his officers precede him and he refused because he would never ask his men to go where he would not lead them. He was counting on Hull to back down and he was right. Without consulting anyone, the American general ordered the gunners not to fire, had a white flag raised in the fort, and sent two officers to ask for terms. Brock sent his aides Colonel MacDonell and Captain Glegg into the fort, where they negotiated Hull's total surrender.
Afterwards, there was some criticism that Brock had acted rashly but in a letter to his brothers, he asserted that he had proceeded "from a cool calculation of the pours and contres." His calculated risk produced a completely unexpected victory with the capture of an American army, fort, and territory (Michigan), as well as great quantities of war materiel. A mood of defeatism in Upper Canada changed to optimism that the troops, militia and Indigenous allies could defend the province.
Battle of Queenston Heights and Death
When the Americans invaded again at Queenston Heights, Brock was awakened from sleep at Fort George and rode hastily to the village. Almost as soon as he arrived, the Americans seized a gun battery on the heights. Brock decided a direct attack was needed immediately without time to wait for reinforcements. His calculated risk proved to be rash, for as he led his troops he was hit in the chest by a shot from an American soldier. Brock died instantly without delivering any of the final words (such as "Push on brave York Volunteers") that have been attributed to him. (See also Canadian Music from Wars and Armed Conflicts.)
The memory of Brock, the hero of Upper Canada, remains extraordinarily strong in Ontario history. His body, interred at Fort George, was moved in 1824 to the summit of Queenston Heights under an imposing monument, which was destroyed in 1840, but replaced in 1853. Today, the stately Brock's Monument dominates the battlefield. Brock University, founded in 1964 in St Catharines, Ontario, is named after Isaac Brock.
