Not content with concluding peace on terms favourable to Prussia, he solicited rank in the Prussian service, dressed himself in a Prussian uniform, wore the Black Eagle of Prussia on his breast, made preparations for visiting Prussia, in order to have an interview with the object of his idolatry, and actually sent fifteen thousand excellent troops to reinforce the shattered army of Frederic. Thus strengthened, the King speedily repaired the losses of the preceding year, reconquered Silesia, defeated Daun at Buckersdorf, invested and retook Schweidnitz, and, at the close of the year, presented to the forces of Maria Theresa a front as formidable as before the great reverses of 1759. Before the end of the campaign, his friend, the emperor Peter, having by a series of absurd insults to the institutions, manners, and feelings of his people, united them in hostility to his person and government, was deposed and murdered. The Empress, who, under the title of Catharine the Second, now assumed the supreme power, was, at the commencement of her administration, by no means partial to Frederic, and refused to permit her troops to remain under his command. But she observed the peace made by her husband; and Prussia was no longer threatened by danger from the East. England and France at the same time paired off together. They concluded a treaty, by which they bound themselves to observe neutrality with respect to the German war. Thus the coalitions on both sides {245}were dissolved; and the original enemies, Austria and Prussia, remained alone confronting each other. Austria had undoubtedly far greater means than Prussia, and was less exhausted by hostilities; yet it seemed hardly possible that Austria could effect alone what she had in vain attempted to effect when supported by France on the one side, and by Russia on the other. Danger also began to menace the Imperial house from another quarter. The Ottoman Porte held threatening; language, and a hundred thousand Turks were mustered on the frontiers of Hungary. The proud and revengeful spirit of the Empress Queen at length gave way; and, in February, 1763, the peace of Hubertsburg put an end to the conflict which had, during seven years, devastated Germany. The King ceded nothing. The whole Continent in arms had proved unable to tear Silesia from that iron grasp.
