In 1756, four expeditions were undertaken in America against the French. One was conducted by General Monckton, who had orders to drive the French from the encroachments on the province of Nova Scotia. This expedition was attended with success. General Johnson was ordered, with a body of troops, to take possession of Crown Point, but he did not succeed. General Shirley commanded an expedition against the fort at Niagara, but lost the season by delay. General Braddock marched against fort Du Quesne, but in penetrating through the wilderness, he incautiously fell into an ambuscade and suffered a total defeat. General Braddock was killed, but a part of his troops were saved by the prudence and bravery of General Washington, at this time a Colonel, who then began to exhibit proofs of those military talents, by which he afterwards conducted the armies of America to victory, and his country to independence. The ill success of these expeditions left the English settlements in America exposed to the depredations of both the French and Indians. But the war now raged in Europe and the East Indies, and engaged the attention of both nations in those quarters.

It was not until the campaign in 1758, that affairs assumed a more favorable aspect in America. But upon a change of administration, Mr. Pitt was appointed Prime Minister, and the operations of war became more vigorous and successful. General Amherst was sent to take possession of Cape Breton; and after a warm siege, the garrison of Louisburgh surrendered by capitulation. General Forbes was successful in taking possession of fort Du Quesne, which the French thought fit to abandon. But General Abercrombie, who commanded the troops destined to act against the French at Crown Point and Ticonderoga, attacked the lines at Ticonderoga, where the enemy were strongly entrenched, and was defeated with a terrible slaughter of his troops. After his defeat, he returned to his camp at Lake George.

The next year, more effectual measures were taken to subdue the French in America. General Prideaux and Sir William Johnson began the operations of the campaign by taking the French fort near Niagara.[45] General Amherst took possession of the forts at Crown Point and Ticonderoga, which the French had abandoned.

But the decisiv blow, which proved fatal to the French interests in America, was the defeat of the French army, and the taking of Quebec, by the brave general Wolfe. This hero was slain in the beginning of the action, on the plains of Abram, and Monsieur Montcalm, the French commander, likewise lost his life. The loss of Quebec was soon followed by the capture of Montreal, by General Amherst, and Canada has remained ever since in possession of the English.

Colonel Grant, in 1761, defeated the Cherokees in Carolina, and obliged them to sue for peace. The next year, Martinico was taken by Admiral Rodney and General Monkton; and also the islands of Grenada, St. Vincents, and others. The capture of these was soon followed by the surrender of the Havanna, the capital of the island of Cuba.

In 1763, a definitiv treaty of peace was concluded at Paris, between Great Britain, France and Spain, by which the English ceded to the French several islands in the West Indies, but were confirmed in the possession of all North America on this side the Missisippi, except New Orleans, and a small district of the neighboring country.

But this war, however brilliant the success, and glorious the event, proved the cause of great and unexpected misfortunes to Great Britain. Engaged with the combined powers of France and Spain, during several years, her exertions were surprising, and her expense immense. To discharge the debts of the nation, the parliament was obliged to have recourse to new expedients for raising money. Previous to the last treaty in 1763, the parliament had been satisfied to raise a revenue from the American Colonies by monopoly of their trade.

At the beginning of the last war with France, commissioners from many of the colonies had assembled at Albany, and proposed that a great council should be formed by deputies from the several colonies, which, with a general Governor to be appointed by the crown, should be empowered to take measures for the common safety, and to raise money for the execution of their designs. This proposal was not relished by the British ministry; but in place of this plan, it was proposed, that the Governors of the colonies, with the assistance of one or two of their council, should assemble and concert measures for the general defence; erect forts, levy troops, and draw on the treasury of England for monies that should be wanted; but the treasury to be reimbursed by a tax on the colonies, to be laid by the English parliament. To this plan, which would imply an avowal of the right of parliament to tax the colonies, the provincial assemblies objected with unshaken firmness. It seems, therefore, that the British parliament, before the war, had it in contemplation to exercise the right they claimed of taxing the colonies at pleasure, without permitting them to be represented. Indeed it is obvious that they laid hold of the alarming situation of the colonies about the year 1754, and 1755, to force them into an acknowlegement of the right, or to the adoption of measures that might afterwards be drawn into precedent. The colonies however, with an uncommon foresight and firmness, defeated all their attempts. The war was carried on by requisitions on the colonies for supplies of men and money, or by voluntary contributions.

But no sooner was peace concluded, than the English parliament resumed the plan of taxing the colonies; and to justify their attempts, said, that the money to be raised, was to be appropriated to defray the expense of defending them in the late war.

The first attempt to raise a revenue in America appeared in the memorable stamp act, passed March 22, 1765; by which it was enacted that certain instruments of writing, as bills, bonds, &c. should not be valid in law, unless drawn on stamped paper, on which a duty was laid. No sooner was this act published in America, than it raised a general alarm. The people were filled with apprehensions at an act which they supposed an attack on their constitutional rights. The colonies petitioned the king and parliament for a redress of the grievance, and formed associations for the purpose of preventing the importation and use of British manufactures, until the act should be repealed. This spirited and unanimous opposition of the Americans produced the desired effect; and on the 18th of March, 1766, the stamp act was repealed. The news of the repeal was received in the colonies with universal joy, and the trade between them and Great Britain was renewed on the most liberal footing.
