Campbell's return to her family in Pennsylvania in 1764 was a result of British military pressure on the Native Americans of southern Ohio by troops under Colonel Henry Bouquet. Over two days, August 5 and August 6, Bouquet's forces prevailed against Native American irregulars in the Battle of Bushy Run, a key battle that turned the tide of Pontiac's Rebellion. While armed conflict became rare after the battle, no formal peace had been made. Starting from Fort Niagara on August 6, 1764, Colonel John Bradstreet and 1,200 of his soldiers moved through northern Ohio on their way to Fort Detroit. Bradstreet concluded a peace treaty with a number of tribes on August 12, which would have prohibited an expedition by Bouquet to the south. General Thomas Gage rejected Bradstreet's treaty on the grounds that the Colonel had exceeded his authority in making it.
