broken up, the auxiliaries sent to their homes, and the Hanoverian troops go into cantonments. To complete the misery of the situation, Frederick had himself suffered a disastrous defeat at Kolin, in Bohemia, while covering the siege of Prague. The extraordinary campaign which saved Prussia does not belong to our history; it is enough to understand, that with extreme rapidity he threw himself towards the western extremity of his widespread dominions, and filled the gap which Cumberland had left open. The great victory of Rosbach, in the neighbourhood of the Saale, over the French and Imperialists, rendered that flank secure for the present. Suddenly darting back again into Silesia, where his affairs had not been going prosperously in his absence, he completely defeated the Austrians at the battle of Lissa, north of the river Schneidwitz, and thus rendered that flank secure also. This year, so disastrous in Europe, had been marked by the signal success of our arms in India, whither Clive, who had come home after his brilliant successes in the Carnatic, had again returned as Governor of Fort St. David. He had been summoned to Bengal to revenge the horrors of the Black Hole of Calcutta, and had there laid the foundation of the English power by the brilliant victory of Plassy.[8] [Sidenote: Change of generals. 1758.] [Sidenote: Success in America.] The disasters which had met the English arms in all directions moved the anger of Pitt, and he determined on a thorough change of generals. In the place of Cumberland, who had shown his inefficiency in the last campaign, Ferdinand of Brunswick, a worthy disciple of Frederick's, was appointed to command the army of Hanover; and as the Convention of Klosterseven was repudiated by the English, he found the defeated army at Stade ready to receive him. Loudon gave place to Amherst and Wolfe. It was in America that the English troops were chiefly employed. The mouth of the St. Lawrence was guarded by Cape Breton Island and Louisburg. At New York the Hudson falls into the sea, and from its mouth there runs northward, nearly into the valley of the St. Lawrence, a valley and chain of lakes, of which the first is Lake Champlain. The fortress which holds the road is Ticonderoga. On the Ohio, as already mentioned, was Fort Duquesne, where Fort Pittsburg now is. The French possessions were to be attacked by each of these three points. Amherst and Wolfe, with a fleet under Boscawen, were to capture Louisburg. Abercrombie was to push up the Hudson and take Ticonderoga, while to Forbes was intrusted the capture of Fort Duquesne. Working hand in hand, without jealousy, Amherst and Boscawen succeeded at once in capturing Louisburg, which had last year been supposed unassailable. Fort Duquesne was also taken. Ticonderoga, strong from its situation in the midst of water and marshes, resisted all efforts, but the line of junction between Canada and the Mississippi was effectually cut.
