American planning On January 13, 1813,
John Armstrong Jr. was appointed
United States Secretary of War. He quickly assessed the situation on Lake Ontario and devised a plan by which a force of 7,000 regular soldiers would be concentrated at Sackett's Harbor on April 1. Working together with Chauncey's squadron, this force would capture Kingston before the
Saint Lawrence River thawed and substantial British reinforcements could arrive in Upper Canada. The capture of Kingston and the destruction of the
Kingston Royal Naval Dockyard together with most of the vessels of the Provincial Marine, would make almost every British post west of Kingston vulnerable if not untenable. After Kingston was captured, the Americans would then capture the British positions at York and
Fort George, at the mouth of the
Niagara River.
John Armstrong Jr. originally planned for an attack on
Kingston, but later acquiesced to changes that made
York the attack's target. Armstrong conferred with Major General
Henry Dearborn, commander of the American
Army of the North, at
Albany, New York during February. Both Dearborn and Chauncey agreed with Armstrong's plan at this point, but they subsequently had second thoughts. That month, Lieutenant General Sir
George Prevost, the British
Governor General of Canada, travelled up the frozen Saint Lawrence to visit Upper Canada. This visit was made necessary because Major General
Roger Hale Sheaffe, who had succeeded Brock as
Lieutenant Governor of Upper Canada, was ill and unable to perform his various duties. Prevost was accompanied only by a few small detachments of reinforcements, which participated in the
Battle of Ogdensburg en route. Nevertheless, both Chauncey and Dearborn believed that Prevost's arrival indicated an imminent attack on Sackett's Harbor, and reported that Kingston now had a garrison of 6,000 or more British
regulars. Even though Prevost soon returned to Lower Canada, and deserters and pro-American Canadian civilians reported that the true size of Kingston's garrison was 600 regulars and 1,400 militia, Chauncey and Dearborn chose to accept the earlier inflated figure. Furthermore, even after two brigades of troops under Brigadier General
Zebulon Pike reinforced the troops at Sackett's Harbor after a gruelling winter march from
Plattsburgh, the number of effective troops available to Dearborn fell far short of the 7,000 planned, mainly as a result of sickness and exposure. During March, Chauncey and Dearborn recommended to Armstrong that when the ice on the lake thawed, they should attack the less well-defended town of York instead of Kingston. Although York was the provincial capital of Upper Canada, it was far less important than Kingston as a military objective. Historians such as John R. Elting have pointed out that this change of plan effectively reversed Armstrong's original strategy, and by committing the bulk of the American forces at the western end of Lake Ontario, it left Sackett's Harbor vulnerable to an attack by British reinforcements arriving from Lower Canada. Armstrong, by now back in Washington, nevertheless acquiesced in this change of plan as Dearborn might well have better local information. Armstrong also believed that an easy victory at York would provide the government with a significant propaganda coup, as well as bolster support for the
Democratic-Republican Party for the gubernatorial election in New York. The attack was originally planned to commence in early April, although a long winter delayed the attack on York by several weeks, threatening the political value of such an attack. In an attempt to overcome these delays, Democratic-Republicans supporters circulated proclamations of victory prior to the battle to the New York electorate. The American naval squadron first attempted to depart from Sackets Harbor on April 23, 1813, although an incoming storm forced the squadron back to harbour, in order to wait out the storm. The squadron finally departed on the next day.
British preparations s that were built to defend York, 1799 The town of York was not heavily fortified, with insufficient resources preventing the construction of necessary works needed to adequately defend it. As a result, Sheaffe had instructed government officials in early April 1813 to hide legislative papers in the forest and fields behind York, to ensure they would not be seized in the event of an attack. York's defences included the town's
blockhouse situated near the
Don River east of the town, the blockhouses at
Fort York to the west, and another
blockhouse at Gibraltar Point. The settlement was also defended by three batteries at the fort and the nearby "Government House Battery" which mounted two 12-pounder
guns. Another crude battery, known as the Western Battery, was located west of the fort, in present-day
Exhibition Place. It contained two obsolete 18-pounder guns, which originated from earlier conflicts and had been disabled by having their
trunnions removed, but they were fixed to crude log carriages and could still be fired. Fort York was also defended by a western wall and a small unarmed
earthwork between the fort and the Western Battery. About a dozen cannons, including older condemned models, were mounted in these positions, in addition to two 6-pounders on field carriages. Further west were the ruins of
Fort Rouillé, and the Half Moon Battery, neither of which was in use. in 1813. Most of the militia and the
8th Regiment of Foot were positioned there prior to the battle. Sheaffe was at York to conduct public business. He was originally scheduled to leave the settlement for
Fort George but had postponed his departure due to suspicions of an American assault on York. His regulars, most of whom were also passing through York en route to other posts, consisted of two companies (including the grenadier company) of the 1st battalion
8th Regiment of Foot, a company of the
Glengarry Light Infantry Fencibles, a company-sized detachment of the
Royal Newfoundland Fencibles, a small squad from the
49th Regiment of Foot, and thirteen soldiers from the
Royal Artillery. There were also 40 or 50
Mississaugas and
Ojibwe warriors, and the
Canadian militia. The American naval squadron was spotted by British sentries posted at the
Scarborough Bluffs on April 26, who alerted the town and its defenders using
flag signals and signal guns. The Militia was ordered to assemble, but only 300 of the 1st and 3rd Regiments of the
York Militia, and a company of the Incorporated Militia, could be mustered at short notice. Sheaffe expected the Americans to launch a two-pronged attack, with the main American landing to the west of Fort York, and another landing in
Scarborough to cut off a potential retreat to Kingston. To counteract this, Sheaffe concentrated most of his regulars, the
Native warriors and a small number of militiamen at Fort York, while most of the militia and the companies of the 8th Regiment of Foot positioned themselves at the town's blockhouse.
