of the 1st Battalion of the Royal Scots to reinforce the attackers; they lost half their men and very few of them even reached the fort. After fighting swayed back and forth for nearly an hour, some Americans turned around an 18-pounder cannon on the rear redan and began to fire into the bastion less than away. The British responded by turning one of the captured cannons around and knocking the American 18-pounder off its carriage. Shortly after the British began firing their captured gun, a large powder magazine in the bastion beneath their feet ignited. The explosion was immense, destroying the entire bastion and most of the attached barracks building. A two-ton cannon was thrown out of the fort. Between 150 and 250 men, mainly British and Canadians, were killed in the bastion. It was gruesomely reported that some attackers were blown from the walls of the fort to land on the bayonets of those still in the ditch. The explosion caused havoc for both sides, although the Americans in the fort were sheltered from the full force of the explosion by the barrack buildings. Lieutenant Douglass was nearly killed when a large piece of flaming timber crushed the man next to him. The surviving attackers were convinced that the entire fort was mined and they retreated in panic. Drummond's column had been almost wiped out during the attack. When the 104th assembled the next day and roll was called, those who were still standing openly wept at the loss of over half of their men who had attacked. Sergeant Richard Smith of the 104th was recommended for a commission for his gallantry in the assault, during which he was wounded five times and subsequently had to have his right arm amputated, but the commission was never awarded. Aftermath In total the British suffered 57 killed, 309 wounded and 537 missing (many of whom were killed in the explosion of the fort's magazine). The journal of surgeon William Dunlop described working on the wounded for nearly 3 days without ceasing. The Americans reported capturing 360 prisoners, 174 of whom were wounded. General Gaines reported that 222 dead British troops were left in and around the fort. This would give a revised British loss of 222 killed, 309 wounded, 360 captured (of whom 174 were wounded) and 12 missing. The garrison suffered 17 killed, 56 wounded and 11 missing. American
