THREE:But Frederick did not seem to think himself at all bound by his treaty obligations with France to refrain from entering into secret arrangements with the foe which would promote his interests, however antagonistic those arrangements might be to his assumed obligations. He was the ally of France in the attempt to wrest territory from the young Queen of Austria, and to weaken her power. His armies and those of France were acting in co-operation. Frederick now proposed to the common enemy that, if Silesia were surrendered to him, he would no longer act in co-operation with his ally; but, that France might not discover his perfidy, he would still pretend to make war. The Austrians were to amuse themselves in defending Neisse from a sham siege until the pleasant weeks of autumn were gone, and then they were to march, with all their guns and ammunition, south to Vienna, there to fight the French. Frederick, still assuming that he was the ally of France, was to avail himself of the excuse that the season of ice and snow was at hand, and withdraw into winter quarters. Such, in general, were the terms which Frederick authorized his minister, Goltz, to propose to Lord Hyndford, as the agent of England and Austria.Berlin was almost defenseless. All Saxony was rising in arms behind Frederick. The invader of Silesia was in danger of having his own realms invaded and his own capital sacked. Frederick was thoroughly roused. But he never allowed himself to appear agitated or anxious. He ordered Leopold, the Old Dessauer, to march immediately, with all the troops he could rally, to the frontiers of Saxony. He even found it necessary to detach to the aid of Leopold some corps from his own enfeebled forces, now menaced by an Austrian army twice as large as he could oppose to them.
