Rivalry for the West, particularly for the valley of the upper Ohio, prepared the way for another war. In 1748 a group of Virginians interested in Western lands formed the Ohio Company, and at the same time the French were investigating possibilities of occupying the upper Ohio region. The French were first to act, moving S from Canada and founding two forts. Robert Dinwiddie, governor of Virginia, sent an emissary, young George Washington, to protest.
The contest between the Ohio Company and the French was now joined and hinged on possession of the spot where the Monongahela and the Allegheny join to form the Ohio (the site of Pittsburgh). The English started a fort there but were expelled by the French, who built Fort Duquesne in 1754. Dinwiddie, after attempting to get aid from the other colonies, sent out an expedition under Washington. He defeated a small force of French and Native Americans but had to withdraw and, building Fort Necessity, held his ground until forced to surrender (July, 1754). The British colonies, alarmed by French activities at their back door, attempted to coordinate their activities in the Albany Congress. War had thus broken out before fighting began in Europe in the Seven Years War (1756–63)
The American conflict, the last and by far the most important of the series, is usually called simply the French and Indian War. The British undertook to capture the French forts in the West—not only Duquesne, but also Fort Frontenac (see Kingston, Ont., Canada), Fort Niagara, and the posts at Ticonderoga and Crown Point. They also set out to take Louisburg and the French cities on the St. Lawrence, Quebec and Montreal. They at first failed in their attempts. The expedition led by Edward Braddock against Duquesne in 1755 was a costly fiasco, and the attempt by Admiral Boscawen to blockade Canada and the first expeditions against Niagara and Crown Point were fruitless.
After 1757, when the British ministry of the elder William Pitt was reconstituted, Pitt was able to supervise the war in America. Affairs then took a better turn for the British. Lord Amherst in 1758 took Louisburg, where James Wolfe distinguished himself. That same year Gen. John Forbes took Fort Duquesne (which became Fort Pitt).
The French Louis Joseph de Montcalm, one of the great commanders of his time, distinguished himself (1758) by repulsing the attack of James Abercromby on Ticonderoga. The next year that fort fell to Amherst. In the West, the hold of Sir William Johnson over the Iroquois and the activities of border troops under his general command—most spectacular, perhaps, were the exploits of the rangers under Robert Rogers—reduced French holdings and influence.
The war became a fight for the St. Lawrence, with Montcalm pitted against the brilliant Wolfe. The climax came in 1759 in the open battle on the Plains of Abraham (see Abraham, Plains of). Both Wolfe and Montcalm were killed, but Quebec fell to the British. In 1760, Montreal also fell, and the war was over. The Treaty of Paris in 1763 (see Paris, Treaty of) ended French control of Canada, which went to Great Britain.
