May, 1813, appointed chief of staff to Major-General Henry Dearborn on the Niagara frontier, New York, and reorganizes the staff departments of the Army.
May 27 commands the advance again in the attack on Fort George, Canada. Every fifth man is killed or wounded. By the explosion of a powder magazine his collar-bone is broken and he is badly bruised; but he is the first to enter the fort and he himself hauls down the colors.
July 18 he resigns his adjutant generalcy in order to be with his regiment as colonel. Leads in several successful skirmishes.
March 9, 1814, aged twenty-eight, is appointed brigadier-general. He has become noted as a student of war—a skilful tactician and a fine disciplinarian. At the Buffalo headquarters he is set at work instructing the officers. The United States has no military text-book, but he has read the French system of military training and employs that.
July 3, 1814, leads with his brigade to the attack upon Fort Erie, opposite Buffalo. Leaps from the first boat into water over his head, and laden with sword, epaulets, cloak and high boots swims for his life under a hot fire, until he can be hauled in again. The fort is captured.
July 4, again leading his brigade he drives the enemy back sixteen miles.
July 5 fights and wins the decisive battle of Chippewa against a much superior force. The war on the land had been going badly for the United States. Now the victory of Chippewa sets bonfires to blazing and bells to ringing throughout all the Republic; the American army had proved itself with the bayonet and General Scott is hailed as the National hero.
July 25 he distinguishes himself again in the night battle of Niagara or Lundy’s Lane. He is twice dismounted, and is bruised by a spent cannon ball. Receives an ounce musket ball through the left shoulder and is insensible for a time. Is borne from the field in an ambulance.
July 25 brevetted major-general for gallantry at Chippewa and Lundy’s Lane.
