The affairs of England, menaced by invasion, were during this time compelling George to draw part of his forces homeward; it was, consequently, only the approach of winter which saved the towns of Flanders from the French. At the same time, the wily Prussian was in arms again, trusting to seize yet more of the Austrian territories, whilst the powerful ally of Maria Theresa was at once pressed by the fault of the Dutch and Austrians in Flanders, and at home by the Pretender. George, who, in spite of all remonstrances, had persisted, notwithstanding the domestic danger, in paying his annual visit to Hanover, was earnestly engaged, through Lord Harrington, in endeavouring to accomplish a peace between Prussia and Austria. Neither Frederick nor Maria Theresa, however, was in any haste to conclude peace. Frederick hoped to profit by the engagement of England with the French, and Maria Theresa held out, with some vague hopes of regaining Silesia through the money of England. But Frederick, on the 3rd of June, gained a decided victory over Prince Charles of Lorraine, throwing himself between the Austrians and the Saxons, whom the English subsidy had brought to their aid. In this battle of Hohen Friedberg the Austrians lost nine thousand men in killed and wounded, and had as many made prisoners. Prince Charles retreated into Bohemia, and was soon followed by Frederick, who fixed his camp at Chlum. Whilst another battle was impending, Maria Theresa, still undaunted, accompanied her husband to the Diet at Frankfort, where she had the satisfaction of seeing him elected Emperor of Germany on the 13th of September. The same month, however, her troops were again defeated by Frederick at Sohr, near the sources of the Elbe. The King of Prussia now offered to make peace, and Maria Theresa rejected his overtures; but another victory over her combined army of Austrians and Saxons, which put Frederick in possession of Dresden, brought her to reason. A peace was concluded at Dresden on Christmas Day, by which Silesia was confirmed to Prussia, and Frederick, on his part, acknowledged the recent election of the Emperor Francis. King George had also entered into a secret treaty with Prussia; and Frederick, sending his army into winter quarters in Silesia, returned to Berlin, thence to ponder fresh schemes of aggrandisement.
