This reference, so prosaically introduced, is really one of enormous moment in our story. The Frobishers, with their keen business instincts and daring plans, saw that the real stroke which would lead them on to fortune was to divert the stream of trade then going to Hudson Bay southward to Lake Superior. Accordingly, with a further aggressive movement in view, Joseph Frobisher established a post on Sturgeon Lake, an enlargement of the Saskatchewan, near the point known by the early French as Poskoiac. A glance at the map will show how well chosen Sturgeon Lake Fort was. Northward from it a watercourse could be readily followed, by which the main line of water communication from the great northern districts to Hudson Bay could be reached and the Northern Indians be interrupted in their annual pilgrimage to the Bay. But, as we shall afterward see, the sleeping giant of the Bay had been awakened and was about to stretch forth his arms to grasp the trade of the interior with a new vigour. Two years after Frobisher had thrown down the pledge of battle, it was taken up by the arrival of Samuel Hearne, an officer of the Hudson's Bay Company, and by his founding Fort Cumberland on Sturgeon Lake, about two miles below Frobisher's Fort. Hearne returned to the Bay, leaving his new fort garrisoned by a number of Orkney men under an English officer. During the same year an explorer, on behalf of the Hudson's Bay Company, visited Red River, but no fort was built there for some time afterward. The building of Fort Cumberland led to a consolidation on the part of the Montreal merchants. In the next year after its building, Alexander Henry, the brothers Frobisher, trader Cadot, and a daring trader named Pond, gathered at Sturgeon Lake, and laid their plans for striking a blow in retaliation, as they regarded it, for the disturbance of trade made by the Hudson's Bay Company in penetrating to the interior from the Bay. Cadot, with four canoes, went west to the Saskatchewan; Pond, with two, to the country on Lake Dauphin; and Henry and the Frobisher brothers, with their ten canoes and upwards of forty men, hastened northward to carry out the project of turning anew the Northern Indians from their usual visit to the Bay. On the way to the Churchill River they built a fort on Beaver Lake. In the following year, a strong party went north to Churchill or English River, as Joseph Frobisher now called it. When it was reached they turned westward and ascended the Churchill, returning at Serpent's Rapid, but sending Thomas Frobisher with goods on to Lake Athabasca.
