"All is lost save the royal family," he wrote to his minister Friesenstein; "the consequences of this battle will be worse than the battle itself. I shall not survive the ruin of the Fatherland. Adieu for ever!" But he soon recovered from his despair, and in 1760 gained the important victories of Liegnitz and Torgau. He had now, however, to act on the defensive, and fortunately for him, the Russians, on the death of the empress Elizabeth, not only withdrew in 1762 from the compact against him, but for a time became his allies. On the 29th of October of that year he gained his last victory over the Austrians at Freiberg. Europe was by that time sick of war, every power being more or less exhausted. The result was that, on the 15th of February 1763, a few days after the conclusion of the peace of Paris, the treaty of Hubertusburg was signed, Austria confirming Prussia in the possession of Silesia. (See SEVEN YEARS' WAR.) It would be difficult to overrate the importance of the contribution thus made by Frederick to the politics of Europe. Prussia was now universally recognized as one of the great powers of the Continent, and she definitely took her place in Germany as the rival of Austria. From this time it was inevitable that there should be a final struggle between the two nations for predominance, and that the smaller German states should group themselves around one or the other. Frederick himself acquired both in Germany and Europe the indefinable influence which springs from the recognition of great gifts that have been proved by great deeds.
