Frederick had been three days and nights at work upon his fortress before the allies ventured forward to look into it. It was then a Gibraltar. Still for eight days more the spade was not intermitted. Cogniazo, an Austrian, writes: It is a masterpiece of art, in which the principles of tactics are combined with those of field fortifications as never before.

CHAPTER XI. DIPLOMATIC INTRIGUES.

The nephew of Elizabeth, and her successor, Peter III., was a very warm admirer of Frederick. One of his first acts was to send to the Prussian king the assurance of his esteem and friendship. Peter immediately released all the Prussian prisoners in his dominions, entered into an armistice with Frederick, which529 was soon followed by a treaty of alliance. The two sovereigns commenced a very friendly correspondence. Frederick returned all the Russian prisoners, well clothed and fed, to their homes. The change was almost as sudden and striking as the transformations in the kaleidoscope. On the 23d Peter issued a decree that there was peace with Prussia, that he had surrendered to his Prussian majesty all the territorial conquests thus far made, and had recalled the Russian armies. Notwithstanding the opposition, Parliament voted to continue the subsidy to Frederick of about three million four hundred thousand dollars (670,000). This sum was equal to twice or three times that amount at the present day.

General Daun was soon informed of this energetic movement. He instantly placed himself at the head of sixty thousand troops, and also set out, at his highest possible speed, for Glatz.

Whereas the Baron De P?llnitz, born of honest parents, so far as we know, having served our grandfather as gentleman of the chamber, Madame DOrleans in the same rank, the King of Spain as colonel, the deceased Emperor Charles VI. as captain of horse, the pope as chamberlain, the Duke of Brunswick as chamberlain, the Duke of Weimar as ensign, our father as chamberlain, and, in fine, us as grand master of ceremonies, has, notwithstanding such accumulation of honors, become disgusted with the world, and requests of us a parting testimony;

The emperor was probably induced to this decisive course not merely by motives of humanity, but also by the consideration that by thus saving the life of Frederick he would forever attach him to the interests of the house of Austria. The kings of Poland and Sweden also wrote to the king, earnestly interceding for the life of the Crown Prince.
