Going northward over the Portage la Prairie, Verendrye's sons had discovered what is now known as Lake Manitoba, and had reached the Saskatchewan River. On the west side of Lake Manitoba they founded Fort Dauphin, while at the west end of the enlargement of the Saskatchewan known as Cedar Lake, they built Fort Bourbon and ascended the Saskatchewan to the forks, which were known as the Poskoiac. Tardy recognition of Verendrye's achievements came from the French Court in the explorer being promoted to the position of captain in the Colonial troops, and a short time after he was given the Cross of the Order of St. Louis. Beauharnois and his successor Galissionière had both stood by Verendrye and done their best for him. Indeed, the explorer was just about to proceed on the great expedition which was to fulfil their hopes of finding the Western Sea, when, on December 6th, he passed away, his dream unrealized. He was an unselfish soul, a man of great executive ability, and one who dearly loved his King and country. He stands out in striking contrast to the Bigots and Jonquières, who disgraced the name of France in the New World.
From the hands of these vampires, who had come to suck out the blood of New France, Verendrye's sons received no consideration. Their claims were coolly passed by, their goods shamelessly seized, and their written and forcible remonstrance made no impression. Legardeur de St. Pierre, more to the mind of the selfish Bigot, was given their place and property, and in 1751 a small fort was built on the upper waters of the Saskatchewan, near the Rocky Mountains, near where the town of Calgary now stands. This was called in honour of the Governor, Fort La Jonquière. A year afterward, St. Pierre, with his little garrison of five men, disgusted with the country, deserted Fort La Reine, which, a few weeks after, was burned to the ground by the Assiniboines.
The fur trade was continued by the French in much the same bounds, so long as the country remained in the hands of France.
We are fortunate in having an account of these affairs given in De Bougainville's Memoir, two years before the capture of Canada by Wolfe. The forts built by Verendrye's successors were included under the "Post of the Western Sea" (La Mer de l'Ouest). Bougainville says, "The Post of the Western Sea is the most advanced toward the north; it is situated amidst many Indian tribes, with whom we trade and who have intercourse with the English, toward Hudson Bay. We have there several forts built of stockades, trusted generally to the care of one or two officers, seven or eight soldiers, and eighty engagés Canadiens. We can push further the discoveries we have made in that country, and communicate even with California."
This would have realized the dream of Verendrye of reaching the Western Sea.
"The Post of La Mer de l'Ouest includes the forts of St. Pierre, St. Charles, Bourbon, De la Reine, Dauphin, Poskoiac, and Des Prairies (De la Jonquière), all of which are built with palisades that can give protection only against the Indians."
"The post of La Mer de l'Ouest merits special attention for two reasons: the first, that it is the nearest to the establishments of the English on Hudson Bay, and from which their movements can be watched; the second, that from this post, the discovery of the Western Sea may be accomplished; but to make this discovery it will be necessary that the travellers give up all view of personal interest."
Two years later, French power in North America came to an end, and a generation afterward, the Western Sea was discovered by British fur traders.
