"The Electors of Bavaria and Saxony," replied Oxenstiern, "have been
paid for their services, which, as vassals, they were bound to render
the Emperor, with the possession of important provinces; and shall we,
who have sacrificed our king for Germany, be dismissed with the
miserable sum of 2,500,000 florins?" The disappointment of their
expectations was the more severe, because the Swedes had calculated upon
being recompensed with the Duchy of Pomerania, the present possessor of
which was old and without heirs. But the succession of this territory
was confirmed by the treaty of Prague to the Elector of Brandenburg; and
all the neighbouring powers declared against allowing the Swedes to
obtain a footing within the empire.

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.
