Expedition against Fort Du Quêsne.

The demolition of fort Frontignac and of the stores which had been collected there, contributed materially, to the success of the expedition against fort Du Quêsne. The conduct of this enterprise had been entrusted to general Forbes, who marched from Philadelphia, about the beginning of July, at the head of the main body of the army, destined for this service, in order to join colonel Bouquet at Raystown. So much time was employed in preparing to move from this place, that the Virginia regulars, commanded by colonel Washington, were not ordered to join the British troops until the month of September. It had been determined not to use the road made by Braddock, but to cut a new one from Raystown to fort du Quêsne. About the time this resolution was formed, and before the army was put in motion, major Grant was detached from the advanced post at Loyal Hannan with eight hundred men, to reconnoitre the fort and the adjacent country. This gentleman invited an attack from the garrison, the result of which was that upwards of three hundred of the detachment were killed and wounded, and major Grant himself was made a prisoner.[163]

Fort Du Quêsne evacuated.

Early in October general Forbes moved from Raystown; but the obstructions to his march were so great that he did not reach fort Du Quêsne until late in November. The garrison, being deserted by the Indians, and too weak to maintain the place against the formidable army which was approaching, abandoned the fort the evening before the arrival of the British, and escaped down the Ohio in boats. The English placed a garrison in it, and changed its name to Pittsburg, in compliment to their popular minister. The acquisition of this post was of great importance to Pennsylvania, Maryland, and Virginia. Its possession had given the French an absolute control over the Indians of the Ohio, who were accustomed to assemble at that place, for the purpose of making their destructive incursions into those colonies. Their route was marked by fire and the scalping knife; and neither age nor sex could afford exemption from their ferocity. The expulsion of the French gave the English entire possession of the country, and produced a complete revolution in the disposition of the Indians inhabiting it. Finding the current of success to be running against their ancient friends, they were willing to reconcile themselves to the most powerful; and all the Indians between the lakes and the Ohio concluded a peace with the English.

Although the events of 1758 did not equal the expectations which had been formed from the force brought into the field, the advantages were decisive. The whole country constituting the original cause of the war, had changed masters, and was in possession of the English. The acquisition of the island of Cape Breton opened the way to Quebec; and their success in the west enabled them to direct all their force against Canada. The colonists, encouraged by this revolution in their affairs, and emboldened, by the conquests already made, to hope for others still more extensive, prepared vigorously on the application of Mr. Pitt, for the farther prosecution of the war.

General Amherst succeeds General Abercrombie.

Late in the year 1758, general Abercrombie was succeeded in the command of the army by major general Amherst, who formed the bold plan of conquering Canada in the course of the ensuing campaign.

1759

The decided superiority of Great Britain at sea, and the great exertions of France in other quarters of the world, still prevented the arrival of such reinforcements as were necessary for the preservation of his most christian majesty's possessions in North America. Plan of the campaign.To take advantage of this weakness, the English proposed to enter Canada by three different routes, with three powerful armies; and to attack all the strongholds by which that country was defended.

It was determined that one division of the army, to be commanded by brigadier general Wolfe, a young officer who had signalised himself in the siege of Louisbourg, should ascend the St. Lawrence, and lay siege to Quebec. A strong fleet was to escort the troops destined for this enterprise, and to co-operate with them.
