On 27 May, the Americans had won the
Battle of Fort George, forcing the British defenders of
Fort George into a hasty retreat. The British commander, Brigadier General
John Vincent, gathered in all his outposts along the
Niagara River, disbanded the militia contingents in his force and retreated to
Burlington Heights (at the west end of
Burlington Bay), with about 1,600 men in total. The Americans under the overall leadership of General
Henry Dearborn, who was elderly and ill, were slow to pursue. A brigade under Brigadier General
William H. Winder first followed up Vincent, but Winder decided that Vincent's forces were too strong to engage, and halted at the Forty Mile Creek. Another brigade joined him, commanded by Brigadier General
John Chandler, who was the senior, and took overall command. Their combined force, numbering 3,400, advanced to
Stoney Creek, where they encamped on 5 June. The two generals set up their headquarters at the Gage Farm, confident of intelligence about the defensive layout of Burlington Heights provided by Aaron Stevens, a former member of the
British Indian Department. Stevens would be captured five months later at the
Battle of Nanticoke Creek and would be one of eight traitors hanged after the
Ancaster Bloody Assize. Vincent sent his deputy assistant adjutant general, Lieutenant Colonel
John Harvey, to reconnoitre the American position. Harvey recommended a night attack, reporting that "the enemy's guards were few and negligent; his line of encampment was long and broken; his artillery was feebly supported; several of his corps were placed too far to the rear to aid in repelling a blow which might be rapidly struck in front". The American dispositions described by Harvey account for the statement in the post-battle report of the U.S. Assistant Adjutant-General that only 1,328 American troops were engaged against the British, out of Chandler's total force of 3,400. Although Vincent accompanied the column, he placed Harvey in command. that he was the cousin of American general
William Henry Harrison. In order to be able to pass through the American lines, he was given the challenge response password for the day – "Wil-Hen-Har" (an abbreviation of Harrison's name). He gave his word of honour that he would not divulge this to the British army. He then revealed the word to Green, who rode his brother-in-law's horse part way, and ran on foot the rest of the way to Burlington Heights. Here, he revealed the password to Lieutenant
James FitzGibbon. He was provided with a sword and uniform and used his knowledge of the terrain to guide the British to the American position. Green was present at the battle. However, it has been suggested that the password was actually obtained by Lieutenant Colonel Harvey. According to an account given after the war by Frederick Snider, a neighbour of the Gages, Harvey had executed a ruse on the first sentry to be accosted. Pretending to be the American officer of the day making grand rounds, he approached the sentry and when challenged, came close to the sentry's ear as if to whisper the countersign. But with bayonet secreted in hand, he grabbed the surprised sentry by the throat and threw him to the ground. With the bayonet at his throat, the sentry gave up the password. This suggestion illustrates the incomplete research into several aspects of the Battle of Stoney Creek. Snider gave this account not long before his death in 1877 and his source for it was the April 1871 issue of
The Canadian Literary Journal. Snider was confusing Harvey with Colonel Murray, June 1813 with December 1813 and Stoney Creek with Youngstown near Fort Niagara. Snider makes several obvious errors, such as "the British General St. Vincent was found some days after wandering about in the woods nearly dead of hunger." His name was Vincent and he did not wander about the woods for days. Snider's source for the provenance of the countersign should thus be considered to be unreliable. ==Battle==
