The area was later secured by British forces in September 1760, when the British Army dispatched its chief scout and intelligence officer, Robert Rogers, along with 200 men and fifteen whale boats to take control of the former French fort. In 1772, Jean-Bonaventure Rousseau received a license to trade with the First Nations living within the vicinity of the mouth of the Humber River. His license was later inherited by his son, Jean Baptiste Rousseau, after his death in 1774. Rousseau maintained several contacts in the area, although did not permanently relocate there until 1792; when he established a trading post near the mouth of the Humber River.
