The American arms were more successful in the north. The French were signally defeated on the borders of Lake George, and their commander, Baron Dieskau, was mortally wounded. The moral effect of this victory, following within a few weeks the discomfiture of Braddock, was very great and salutary in its influence upon the colonies.

In the year, 1756, war was formally declared between Great Britain and France; and in Europe began what is called the seven years’ war, in which Prussia was united with England against France. In America the campaign of 1756 was very disastrous to the colonists; they were unable even to attempt gaining of Niagara and Crown Point, places of great importance in the hands of the French, and the reduction of which was in the plan of operations. The French, under Montcalm, took Fort Oswego, thus gaining entire command of the Lakes Ontario and Erie, besides inflicting upon the English a very severe loss, amounting to sixteen hundred men made prisoners, one hundred and twenty cannon, with fourteen mortars, two sloops-of-war, and two hundred bateaux.

The British government made great preparations for the campaign of 1757. A large force was destined for the reduction of Louisburg; but the indecision and incapacity of Lord Loudon, the commander-in-chief, caused the expedition to be abandoned. Meantime, Montcalm, the French commander, besieged and took Fort William Henry, on Lake George, after a most spirited defense by Colonel Munroe. The English troops, after being admitted to honorable capitulation, were treacherously massacred by the Indians attached to Montcalm’s army.

The campaign of 1758 was more prosperous. Lord Chatham had now become prime minister, and infused new energy into the prosecution of the war. In answer to a call made by him upon the colonies, Massachusetts, Connecticut, and New Hampshire, united and raised fifteen thousand men. The tide of success now turned in favor of the English. Three expeditions had been planned: one against Louisburg, another against Ticonderoga, and the third against Fort du Quesne on the Ohio. Louisburg was taken, with great loss to the French in prisoners, ships, and munitions of war. Fort du Quesne was abandoned by the French, taken possession of by the English, and named Pittsburgh. The expedition against Ticonderoga failed, but the failure was compensated by the capture of Fort Frontinac, an important fortress at the outlet of Lake Ontario.

The campaign of 1759 commenced with a nearly simultaneous attack upon all the French strongholds in Canada, namely, Ticonderoga, Crown Point, Niagara, and Quebec. One division of the army, under General Amherst, the commander-in-chief, proceeded against Ticonderoga and Crown Point, which were successively taken. Another division, under General Prideaux, advanced and took Niagara. General Wolfe was no less successful in the great enterprise of conquering Quebec. The French, under Montcalm, were defeated on the plains of Abraham, and Quebec fell into the hands of the British. General Wolfe died upon the field of battle.

In 1760, the French made an unsucessful attempt to recover Quebec. In less than a year from the capture of that city, Montreal, Detroit, and all other places in the possession of the French, were surrendered to the British, and the conquest of Canada was completed.

By the treaty of peace definitively concluded at Paris in 1763, Nova Scotia, Canada, Cape Breton, and all other islands in the gulf and river St. Lawrence, were ceded to the British crown.

The protracted contest with the French and the Indians being brought to a close by the complete triumph of the English, the American Colonies were seemingly in the full tide of prosperity. The great exertions they had made during the last war had taught them the secret of their strength; that war had cost them, it was computed, about 30,000 lives and over sixteen millions of dollars, of which only five millions were repaid by the British ministry. Immigration rapidly increased, and the vast forest in the interior began to be explored by those who were in search of a new home. The Delaware and Hudson rivers were crossed by a thronging multitude, the Alleghanies were surmounted, and white settlements were formed upon the upper tributaries of the Ohio. No longer hemmed in, as with a ring of iron, by the French and the savages, the internal principle of expansion, which has been at work ever since, received its first free development, and carried the limits of civilization every year farther west. Trade flourished on the sea-coast; Boston had long been distinguished for enterprising traffic, and Newport, New York, Philadelphia, and Baltimore were rising rapidly in commercial importance. Printing presses and newspapers, schools and colleges, flourished, though the literature of the Colonies as yet existed only in the humble form of sermons. Yet the metaphysical writings of Jonathan Edwards slowly acquired a European reputation, and the fame of Dr. Franklin was carried, by his brilliant discoveries in electricity, to the bounds of the civilized world.

THE WAR OF AMERICAN INDEPENDENCE.

But the prosperity of America was now to receive a sudden check, and a contest to begin, more important to her and more momentous in its consequences, than any which the world had ever witnessed. England was oppressed by a heavy debt, which had been more than doubled by the heavy expenses of the late war, and the people were overburdened with taxes. In an evil hour, it occurred to the Chancellor of the Exchequer that this pressure might be lightened, if the American Colonies could be made to contribute to the general expenses of the empire.
