 inland slope of the Alleghanies, where the waters fall towards the Gulf of Mexico, at the confluence of the Monongahela with the Ohio, a French officer, Duquesne, built a fort, the most important of all, which closed the interior to our colonies, but which has undergone a significant change of name, for Fort Duquesne is called after Pitt, and is the Birmingham of America.

This annexation of debatable land was an act of aggression to which the colonists were not bound to submit. The first to understand that it was a question of existence was the man on whose head the destinies of the country rested. Washington twice led expeditions against Duquesne, the second time with Regulars under Braddock, and was each time defeated. The question of the possession of the interior was left to be decided on the Heights of Abraham. It was worth more to the English people than any continental issue. The quarrel spread to the ocean, and we made no scruple to assail French ships wherever the conditions were favourable.

Kaunitz, the minister of Maria Theresa, saw his opportunity for a grand stroke of policy. By transplanting the struggle from the New World to the Old, and from sea to land, he would obtain a French alliance against Prussia. Ostensibly his purpose was the recovery of the lost province; but the circumstances seemed promising, and he spoke of reducing Frederic to the position of a margrave of Brandenburg. He asked, at first, for no assistance in the field. If France would set up an army of observation on the frontier, the house of Hanover would be disabled from joining Prussia. France was glad, in a quiet way, to check the House of Hanover. By degrees a complete understanding was achieved, and Lewis XV. undertook to help Austria with an army in the field and a vast sum of money. Belgium was to be the price of it, partly for France, partly for the Bourbon, who was Duke of Parma, in exchange for his Italian dominions. This change of front was much facilitated by the civilities of Kaunitz to the person whom the Austrian envoy described as the French Prime Minister, Madame de Pompadour.
