On 13 August, Drummond opened fire on the fort with two light 24-pounder field guns and four 18-pounder or 24-pounder naval guns. Because the bombardment was fired from too long a range, it was ineffective against the fort's walls. Colonel Scott and Lieutenant Colonel Drummond were both experienced soldiers and had little confidence in General Drummond's plan. Both men arranged their affairs before heading into battle, sending their papers home to their wives. Drummond gave away his sword (a gift from
Lloyd's of London) to Surgeon
William "Tiger" Dunlop of the 89th. Shortly before moving out, both men wished each other luck and bade farewell. The columns moved out after dark, but the garrison at the fort had seen their preparations. Surprise would be nearly impossible to achieve. While Fischer's column made its long march to the south of Snake Hill, Scott's and Drummond's columns waited in the pouring rain in a ravine a few hundred yards north of the fort. An hour before the assault began, the British bombardment of the fort ceased, having inflicted casualties on the garrison of 10 killed and 35 wounded.
American preparations In the fort, Gaines ordered his men to stand to. This produced rumblings from the troops forced to stand in their positions in heavy rain but would prove invaluable in the coming battle. He also ordered that the charges in all guns were to be drawn and replaced, ensuring the guns would not misfire through damp powder. Ripley defended Snake Hill with the 21st and 23rd U.S. Infantry. The Hill was topped with a large gun emplacement containing six guns under the command of Captain
Nathaniel Towson. The fort itself was defended by two companies of the 19th U.S. Infantry, and three guns under Captains Williams and Gookin. The wall between the fort and the Douglass Battery (which held one gun) was manned by the 9th U.S. Infantry, a company of volunteers from the New York and Pennsylvania state militias, the dismounted New York Volunteer Dragoons, and another gun. The long wall between the fort and the Snake Hill, which was not attacked, was defended by Brigadier General
Peter B. Porter with detachments of the 1st and
4th U.S. Rifle Regiments, the 5th Pennsylvania Volunteers, Swift's Regiment of Detached New York Militia, and five guns. Finally, two companies of the 11th and 22nd U.S. Infantry and a detachment of the U.S. Light Dragoons were in reserve. The column encountered an American picket from the defenses. Surprise was nearly achieved but because of the rainy weather, the British troops' advance was betrayed by the loud swishing sound made as they passed through high grass. The picket opened fire, alerting the garrison, before hastily retreating. The leading attackers rushed forward to the abatis. As they reached it, Towson opened fire. The rate of fire from his battery would earn it the nickname "Towson's Lighthouse". After several attempts to storm the battery, many attackers broke and fled in panic, sweeping away the steady soldiers to their rear. Those who did try to scale the defenses found that many of the siege ladders built for the attack had been made without taking the ditches into account and were as much as too short to get over the wall. The light company of De Watteville's Regiment attempted to bypass the defenses by swimming in the Niagara River. The current proved to be too swift, and many of the men were swept away to their death; those who survived were quickly captured. commanded the American section that fended off the British attack led by Lieutenant Colonel Victor Fischer. Some of the attackers charged the battery five times before retiring. Some units, such as the light company of the 8th, lost two thirds of their strength. De Watteville's regiment had 144 casualties (although many were "missing" and actually hid in the woods before deserting the next morning). Ripley, commanding this section of the American defenses, reported taking 147 prisoners. His men suffered only a dozen casualties. Fischer's column reeled back in confusion and it was decided another attempt was impossible.
William Drummond's attack Lieutenant Colonel William Drummond's column consisted of a small detachment of gunners of the
Royal Artillery, the flank companies of the 41st Foot and of the 104th Foot, fifty Royal Marines and ninety seamen of the
Royal Navy under Commander Dobbs. The attack on the fort initially made little headway. Using the cover of darkness and the heavy smoke that hung over the field, Drummond then moved his men through the defensive ditch to assault the northeast bastion. The British caught the U.S. artillerymen there completely by surprise, and they quickly abandoned their guns and fled. Those under Captain John Williams and Lieutenant Patrick McDonogh who stood and fought were quickly killed as Drummond cried out "Give no Quarter to the Damn Yankees!" A group of soldiers from the 19th US Infantry (recruits from Ohio who had arrived late the previous evening under Major William Trimble) reorganized themselves in the parade square and poured fire into the bastion. It is believed that Drummond was killed in this barrage. According to one American soldier, in the thick of the fighting he saw a "Red-coated demon, armed with a
pike and screaming for his own death which we quickly obliged him to. He fell not far from our feet, no less than a musket's length away". The attackers twice charged through a gap wide between the two barrack buildings into the parade ground, but were unable to break into the barrack buildings and mess hall. The defenders in turn tried to recapture the northeast bastion but were driven back. General Drummond sent only two companies 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. Gaines reported that the bodies of 222 dead attackers were left in and around the fort. ==American sorties==
