It was not in the Old World only that the year of Minden and Quiberon brought glory to the arms of England. In Europe, Pitt had wisely limited his efforts to the support of Prussia, but across the Atlantic the field was wholly his own, and he had no sooner entered office than the desultory raids, which had hitherto been the only resistance to French aggression, were superseded by a large and comprehensive plan of attack. The sympathies of the colonies were won by an order which gave their provincial officers equal rank with the royal officers in the field. They raised at Pitt's call twenty thousand men, and taxed themselves heavily for their support. Three expeditions were simultaneously directed against the French line--one to the Ohio valley, one against Ticonderoga on Lake Champlain, while a third under General Amherst and Admiral Boscawen sailed to the mouth of the St. Lawrence. The last was brilliantly successful. Louisburg, though defended by a garrison of five thousand men, was taken with the fleet in its harbour, and the whole province of Cape Breton reduced. The American militia supported the British troops in a vigorous campaign against the forts; and though Montcalm, with a far inferior force, was able to repulse General Abercromby from Ticonderoga, a force from Philadelphia and Virginia, guided and inspired by the courage of George Washington, made itself master of Duquesne. The name of Pittsburg which was given to their new conquest still commemorates the enthusiasm of the colonists for the great Minister who first opened to them the West. The failure at Ticonderoga only spurred Pitt to greater efforts. The colonists again responded to his call with fresh supplies of troops, and Montcalm felt that all was over. The disproportion indeed of strength was enormous. Of regular French troops and Canadians alike he could muster only ten thousand, while his enemies numbered fifty thousand men. The next year (1759) saw Montcalm's previous victory rendered fruitless by the evacuation of Ticonderoga before the advance of Amherst, and by the capture of Fort Niagara after the defeat of an Indian force which marched to its relief. The capture of the three forts was the close of the French effort to bar the advance of the colonists to the valley of the Mississippi, and to place in other than English hands the destinies of North America.
