Early in 1813, he opened a campaign in northern Germany, where the emperor of Russia, now joined by the king of Prussia and various minor powers, appeared in the open field against him. After various successes on both sides, an armistice was agreed to on the 1st of June, and Bonaparte was offered peace on condition of restoring only that part of his dominions which he had acquired since 1805. Inspired with an overweening confidence in his resources and military genius, he refused these terms, and lost all. In August, when the armistice was at an end, his father-in-law, the emperor of Austria, joined the allies, whose forces now numbered 500,000 men, while an army of 300,000 was the largest which Napoleon could at present bring into the field. Henceforth he might be considered as overpowered by numbers. By steady, though cautious movements, the allies advanced to France, driving him reluctantly before them, and increasing their own force as the various states became emancipated by their presence. At the close of 1813, they rested upon the frontiers of France, while Lord Wellington, after two successful campaigns in Spain, had advanced in like manner to the Pyrenees. HOME AFFAIRS――WAR WITH AMERICA. Some changes had in the meantime taken place in the British administration. On the 11th of May, 1812, the premier, Mr. Perceval, was shot in the lobby of the House of Commons, by a man named Bellingham, whom some private losses had rendered insane. Lords Liverpool and Castlereagh then became the ministerial leaders in the two Houses of Parliament, but were quickly voted down by a majority of four, upon a motion made by Mr. Stuart Wortley, afterwards Lord Wharncliffe. The ministry was finally rendered satisfactory to Parliament by the admission of Earl Harrowby as president of the council, Mr. Vansittart as chancellor of the exchequer, and Lord Sidmouth (formerly premier while Mr. Addington) as secretary for the home department; Lord Liverpool continuing as premier, and Lord Castlereagh as foreign and war secretary. Notwithstanding the successes which were at this period brightening the prospects of Britain, the regent and his ministers did not enjoy much popularity. The regent himself did not possess those domestic virtues which are esteemed by the British people, and he had excited much disapprobation by the steps which he took for fixing a criminal charge upon his consort. The general discontents were increased by the effects of the orders in council, for prohibiting the commerce of neutral states. Vast multitudes of working people were thrown idle by the stagnation of manufactures, and manifested their feelings in commotion and riot. The middle classes expressed their dissatisfaction by clamors for parliamentary reform.
