"After the disastrous battle at Moraviantown where the British were badly defeated and were obliged to retreat to the Niagara River, giving up the whole western portion of the Province, LeBreton volunteered and was sent with a flag of truce toGeneral Harrison to arrange for an exchange of prisoners."[Source]
More about what happened in the aftermath of LeBreton's encounter with General Harrison (excerpted below*):
*"General Harrison received, by messenger Lieutenant Le Breton, a letter from Major General Proctor dated October 18th (place of writing not given) addressed to him at the Moravian towns by the Thames but delivered at Detroit before his departure from that place."
"Lieutenant Le Breton was given good opportunity to see that the proprieties of civilization had been complied with in regard to the British. He was not permitted to return by land, however, but was taken across Lake Erie in boat with General Harrison."
Note: In other actions, LeBreton was severely wounded at Lundy's Lane.
...when an Indian Nation contains more than about 2,000 people its increase of population decreases its cohesive power. But in the division of the Sauks, which occurred with the late war between Great Britain and the United States, this custom or weakness was not a factor. That division grew out and was a part of the war of 1812- 14.
For more than forty years Mucketee-Meshe-Kiah-Kiah, (literally meaning in our language Black Sparrow Hawk but always called Black Hawk), prior to that war had been the universally acknowledged first or head War Chief of the Sauk Nation.
Living at Saukenuk, near Rock Island, and "out of a job," as he [Black Hawk] had no immediate fight on his hands, but eager to have, on learning that war had been declared, hastened to offer his services with two hundred picked braves, to our Government to fight against the British. On being refused, he at once tendered his services to the British, and was accepted, and went to Green Bay, where he was assigned to duty with the rank of Colonel.
During his [Black Hawk's] absence a rumor reached Saukenuk that a large force of United States troops had left Peoria, Illinois, for an attack upon Saukenuk, which created great alarm among the Sauks, who, as a mass, sympathized with the people of the United States in this war. [Keokuk]...organized a small army sent out spies and went in person at the head of a little band of trailers towards Peoria and satisfied himself that the whole story was a canard.
When Black Hawk and his 200 braves returned from the war, he found Keokuk fully installed in his place as the War Chief of the Nation, and a division of the tribe ensued. ...[one group was] known as the British or Black Hawk's band; the latter as the Peace or Keokuk's band.

Abstract: Morning reports, August-October 1814, of Captain Andrew Stevenson's artillery company, 2nd Infantry Regiment, Virginia militia, consisting mainly of requisitions for supplies and of company returns.
My ancestor, William Hinds, was a member of Virginia's 2nd Artillery; he died on 25 June 1813, months before the above record was generated.
Before daylight on the morning of the 13th of October. a large of General Van Rensselaer's army, numbering between thirteen and fourteen hundred, under Brigadier General Wadsworth, effected a landing the lower end of the Village of Queenston, (opposite Lewiston) and an attack upon the position which was defended with the utmost determined bravery by the two flank companies of the 49th Regiment, commanded by Captains Dennis and Williams, aided by such of the forces and Indians as could be collected in the vicinity.
A considerable force, however, had effected a landing some distance above, and succeeded in gaining the summit of the mountain. No resistance could now be offered to the crossing from Lewiston, except by the battery at Vromont's Point,, half a mile below and from this a steady and harassing fire was kept up which did considerable execution.
