Forts Presqu'isle, Le Boeuf, and Venango, on the trade-route between Lake Erie and Fort Pitt, and Fort Pitt itself, were also occupied.

But all west of Fort Pitt was to the British unknown country.

Sandusky, at the south-west end of Lake Erie; Detroit, guarding the passage between Lakes Erie and St Clair; Miami and Ouiatanon, on the trade-route between Lake Erie and the Wabash; Michilimackinac, at the entrance to Lake Michigan; Green Bay (La Baye), at the southern end of Green Bay; St Joseph, on Lake Michigan; Sault Ste Marie, at the entrance to Lake Superior--all were still commanded by French officers, as they had been under New France.
The task of raising the British flag over these forts was entrusted to Major Robert Rogers of New England, who commanded Rogers's Rangers, a famous body of Indian-fighters.

On September 13, 1760, with two hundred Rangers in fifteen whale-boats, Rogers set out from Montreal.

On November 7 the contingent without mishap reached a river named by Rogers the Chogage, evidently the Cuyahoga, on the south shore of Lake Erie.
