In 1757 the tide of the war began to turn. William Pitt had been appointed prime minister in New England. He saw the French and Indian War as the key to winning the Seven Years' War and establishing a vast British empire. In order to finance the war he borrowed heavily and put Britian into a great deal of debt. This was to first reimburse the colonies for the raising of troops, then hire mercernaries to fight the Seven Years' War in Europe so the British army could be sent to fight in North America. Along with this Pitt appointed capable commanders to the French and Indian War and put much emphasis on the acquiring of Indian allies. 

 

        Soon enough with William Pitt's policies the British began to see success. First Sir William Johnson with a great deal of effort managed to persaude the Iroqouis Indians from joining sides with the French. They in turn, compelled the Delawares to cease their fighting with the British. Then in 1758 the British failed to take Fort Carillon (Ticonderoga), but were capable of the capture of Louisbourg and Fort Frontenac.

 

        In October 1758, the British produced the Treaty of Easton with the Indians. It enlisted substantial Indian support at the cost of certain financial considerations, and a promise to withdraw from the Ohio River country and never settle west of the Appalachians. With help from the Indians, General John Forbes cut a trail through the Pennsylvania wilderness and forced the French to flee from Fort Duquesne, which he promptly named thereafter as Fort Pitt. Then in 1759 the British with their Iroqouis allies took Fort Niagara. 

 

        The new vulnerability of the French in the Great Lakes area caused them to abandon Fort Carillon and Crown Point and withdraw into Canada. Afterwards in the September of 1759, British general James Wolfe defeated the French army commanded by Marquis Louis-Joseph de Montcalm, on the Plains of Abraham outside the city of Quebec. This resulted in the city's surrender and the city of Montreal under Marquis de Vaudreuil soon surrendered afterwards, marking the end of the French and Indian War. The Treaty of Paris in 1763 would officially cease the conflict between England and France. In the treaty England acquired Canada and Spanish Florida, and due to the war it was now the only dominant power in North America.
