From the moment Dearborn turned away from the St. Lawrence and carried the war westward, the naval and military movements on Lake Ontario became valuable chiefly as a record of failure. The fleet and army arrived at York early in the morning of April 27. York, a village numbering in 1806, according to British account, more than three thousand inhabitants, was the capital of Upper Canada, and contained the residence of the lieutenant-governor and the two brick buildings where the Legislature met. For military purposes the place was valueless, but it had been used for the construction of a few war-vessels, and Chauncey represented, through Dearborn, that “to take or destroy the armed vessels at York will give us the complete command of the Lake.” The military force at York, according to British account, did not exceed six hundred men, regulars and militia; and of these, one hundred and eighty men, or two companies of the Eighth or King’s regiment, happened to be there only in passing.[165]

Under the fire of the fleet and riflemen, Pike’s brigade was set ashore; the British garrison, after a sharp resistance, was driven away, and the town capitulated. The ship on the stocks was burned; the ten-gun brig “Gloucester” was made prize; the stores were destroyed or shipped; some three hundred prisoners were taken; and the public buildings, including the houses of Assembly, were burned. The destruction of the Assembly houses, afterward alleged as ground for retaliation against the capitol at Washington, was probably the unauthorized act of private soldiers. Dearborn protested that it was done without his knowledge and against his orders.[166]

The success cost far more than it was worth. The explosion of a powder magazine, near which the American advance halted, injured a large number of men on both sides. Not less than three hundred and twenty Americans were killed or wounded in the battle or explosion,[167] or about one fifth of the entire force. General Pike, the best brigadier then in the service, was killed. Only two or three battles in the entire war were equally bloody.[168] “Unfortunately the enemy’s armed ship the ‘Prince Regent,’” reported Dearborn,[169] “left this place for Kingston four days before we arrived.”

Chauncey and Dearborn crossed to Niagara, while the troops remained some ten days at York, and were then disembarked at Niagara, May 8, according to Dearborn’s report, “in a very sickly and depressed state; a large proportion of the officers and men were sickly and debilitated.”[170] Nothing was ready for the movement which was to drive the British from Fort George, and before active operations could begin, Dearborn fell ill. The details of command fell to his chief-of-staff, Colonel Winfield Scott.

The military organization at Niagara was at best unfortunate. One of Secretary Armstrong’s earliest measures was to issue the military order previously arranged by Monroe, dividing the Union into military districts. Vermont and the State of New York north of the highlands formed the Ninth Military District, under Major-General Dearborn. In the Ninth District were three points of activity,—Plattsburg on Lake Champlain, Sackett’s Harbor on Lake Ontario, and the Niagara River. Each point required a large force and a commander of the highest ability; but in May, 1813, Plattsburg and Sackett’s Harbor were denuded of troops and officers, who were all drawn to Niagara, where they formed three brigades, commanded by Brigadier-Generals John P. Boyd, who succeeded Pike, John Chandler, and W. H. Winder. Niagara and the troops in its neighborhood were under the command of Major-General Morgan Lewis, a man of ability, but possessing neither the youth nor the energy to lead an army in the field, while Boyd, Chandler, and Winder were competent only to command regiments.

Winfield Scott in effect assumed control of the army, and undertook to carry out Van Rensselaer’s plan of the year before for attacking Fort George in the rear, from the Lake. The task was not very difficult. Chauncey controlled the Lake, and his fleet was at hand to transfer the troops. Dearborn’s force numbered certainly not less than four thousand rank-and-file present for duty. The entire British regular force on the Niagara River did not exceed eighteen hundred rank-and-file, and about five hundred militia.[171] At Fort George about one thousand regulars and three hundred militia were stationed, and the military object to be gained by the Americans was not so much the capture of Fort George, which was then not defensible, as that of its garrison.

Early on the morning of May 27, when the mist cleared away, the British General Vincent saw Chauncey’s fleet, “in an extended line of more than two miles,” standing toward the shore. When the ships took position, “the fire from the shipping so completely enfiladed and scoured the plains, that it became impossible to approach the beach,” and Vincent could only concentrate his force between the Fort and the enemy, waiting attack. Winfield Scott at the head of an advance division first landed, followed by the brigades of Boyd, Winder, and Chandler, and after a sharp skirmish drove the British back along the Lake shore, advancing under cover of the fleet. Vincent’s report continued:[172]

“After awaiting the approach of the enemy for about half an hour I received authentic information that his force, consisting of from four to five thousand men, had reformed his columns and was making an effort to turn my right flank. Having given orders for the fort to be evacuated, the guns to be spiked, and the ammunition destroyed, the troops under my command were put in motion, and marched across the country in a line parallel to the Niagara River, toward the position near the Beaver Dam beyond Queenston mountain.... Having assembled my whole force the following morning, which did not exceed sixteen hundred men, I continued my march toward the head of the Lake.”

Vincent lost severely in proportion to his numbers, for fifty-one men were killed, and three hundred and five were wounded or missing, chiefly in the Eighth or King’s regiment.[173] Several hundred militia were captured in his retreat. The American loss was about forty killed and one hundred and twenty wounded. According to General Morgan Lewis, Col. Winfield Scott “fought nine-tenths of the battle.”[174] Dearborn watched the movements from the fleet.

For a time this success made a deep impression on the military administration of Canada, and the abandonment of the whole country west of Kingston was thought inevitable.[175] The opportunity for achieving a decided advantage was the best that occurred for the Americans during the entire war; but whatever might be said in public, the battle of Fort George was a disappointment to the War Department[176] as well as to the officers in command of the American army, who had hoped to destroy the British force. The chief advantage gained was the liberation of Perry’s vessels at Black Rock above the Falls, which enabled Perry to complete his fleet on Lake Erie.
