being refused their traditional post on the right: but this only made the difference that a few less fell on both sides. Against discipline and steadiness they had never had a chance of victory. The treaty of Aix-la-Chapelle, 1748, put an end to the European war, and made formal peace between England and France. The differences between the two great rivals outside Europe were however in no way removed: it can scarcely be said that in India or America the peace was ever more than nominal. The French attempt to connect their possessions in Canada with Louisiana gave the English colonies no option but armed resistance, unless they were prepared to abandon all prospect of extension westwards. For some time the contest was carried on in the region of the Ohio, without involving a formal breach between the two nations. In 1756 however, a coalition was formed between Austria, France, Russia, and Saxony for the dismemberment of the Prussian monarchy, which had risen to considerable power under Frederick the Great. Great Britain naturally allied herself with the enemy of France, and English subsidies were of great value to Frederick in his skilful and substantially successful resistance to enormous odds. The part taken by English arms in the war in Germany was not very important. The duke of Cumberland's blundering campaign, which ended in the convention of Closterseven, was made with Hanoverian and other German troops. More than one expedition against the French coast proved practically abortive. In 1759 however British troops had a conspicuous share in the important victory of Minden.
