As soon as news of Croghan's success reached Fort Pitt, Captain Thomas Sterling, with one hundred and twenty men of the Black Watch, set out in boats for the Mississippi, arriving on October 9 at Fort Chartres, the first British troops to set foot in that country.

Next day Saint-Ange handed the keys of the fort to Sterling, and the Union Jack was flung aloft.

Thus, nearly three years after the signing of the Treaty of Paris, the fleurs-de-lis disappeared from the territory then known as Canada.
There is still to record the closing act in the public career of Pontiac.

Sir William Johnson, fearing that the Ottawa chief might fail to keep his promise of visiting Oswego to ratify the treaty made with Croghan at Detroit, sent Hugh Crawford, in March 1766, with belts and messages to the chiefs of the Ottawa Confederacy.

But Pontiac was already preparing for his journey eastward.
