Never, in the whole course of the war, had the prospects of the Swedes looked more gloomy, than in the year 1635, immediately after the conclusion of the treaty of Prague. Many of their allies, particularly among the free cities, abandoned them to benefit by the peace; others were compelled to accede to it by the victorious arms of the Emperor. Augsburg, subdued by famine, surrendered under the severest conditions; Wurtzburg and Coburg were lost to the Austrians. The League of Heilbronn was formally dissolved. Nearly the whole of Upper Germany, the chief seat of the Swedish power, was reduced under the Emperor. Saxony, on the strength of the treaty of Prague, demanded the evacuation of Thuringia, Halberstadt, and Magdeburg. Philipsburg, the military depot of France, was surprised by the Austrians, with all the stores it contained; and this severe loss checked the activity of France. To complete the embarrassments of Sweden, the truce with Poland was drawing to a close. To support a war at the same time with Poland and in Germany, was far beyond the power of Sweden; and all that remained was to choose between them. Pride and ambition declared in favour of continuing the German war, at whatever sacrifice on the side of Poland. An army, however, was necessary to command the respect of Poland, and to give weight to Sweden in any negotiations for a truce or a peace. The mind of Oxenstiern, firm, and inexhaustible in expedients, set itself manfully to meet these calamities, which all combined to overwhelm Sweden; and his shrewd understanding taught him how to turn even misfortunes to his advantage. The defection of so many German cities of the empire deprived him, it is true, of a great part of his former allies, but at the same time it freed him from the necessity of paying any regard to their interests. The more the number of his enemies increased, the more provinces and magazines were opened to his troops. The gross ingratitude of the States, and the haughty contempt with which the Emperor behaved, (who did not even condescend to treat directly with him about a peace,) excited in him the courage of despair, and a noble determination to maintain the struggle to the last. The continuance of war, however unfortunate it might prove, could not render the situation of Sweden worse than it now was; and if Germany was to be evacuated, it was at least better and nobler to do so sword in hand, and to yield to force rather than to fear.
