THREE:The King of Poland, who was also Elector of Saxony, had strong feelings of personal hostility to Frederick. His prime minister, Count Von Brühl, even surpassed his royal master in the bitter antagonism with which he regarded the Prussian monarch. Frederick, whose eagle eye was ever open, and whose restless mind was always on the alert, suspected that a coalition was about to be formed against him. He had false keys made to the royal archives at Dresden; bribed one of the officials there, M. Menzel, stealthily to enter the chamber of the archives, and copy for him such extracts as would throw any light upon the designs of the court. Among other items of intelligence, he found that Austria, Russia, and Poland were deliberating upon the terms of a coalition against him.It will be remembered that Breslau, whose inhabitants were mainly Protestant, and which was one of the so-called free cities of Germany, was surrendered to Frederick under peculiar conditions. It was to remain, in its internal government, in all respects exactly as it had been, with the simple exception that it was to recognize the sovereignty of Prussia instead of that of Austria. Its strict neutrality was to be respected. It was to be protected by its own garrison. No Prussian soldier could enter with any weapons but side-arms. The king himself, in entering the city, could be accompanied only by thirty guards.
