Maria Theresa's feelings may be conceived; George II's feelings; and what the Cause of Liberty in general felt, and furiously said and complained, when--suddenly as a DEUS EX MACHINA, or Supernal Genie in the Minor Theatres--Friedrich stept in. Precisely in this supreme crisis, 7th August, 1744, Friedrich's Minister, Graf von Dohna, at Vienna, has given notice of the Frankfurt Union, and solemn Engagement entered into: "Obliged in honor and conscience; will and must now step forth to right an injured Kaiser; cannot stand these high procedures against an Imperial Majesty chosen by all the Princes of the Reich, this unheard-of protest that the Kaiser is no Kaiser, as if all Germany were but Austria and the Queen of Hungary's. Prussian Majesty has not the least quarrel of his own with the Queen of Hungary, stands true, and will stand, by the Treaty of Berlin and Breslau;--only, with certain other German Princes, has done what all German Princes and peoples not Austrian are bound to do, on behalf of their down-trodden Kaiser, formed a Union of Frankfurt; and will, with armed hand if indispensable, endeavor to see right done in that matter." [In _Adelung,_ iv. 155, 156, the Declaration itself (Audience, "7th August, 1744." Dohna off homeward "on the second day after").] This is the astonishing fact for the Cause of Liberty; and no clamor and execration will avail anything. This man is prompt, too; does not linger in getting out his Sword, when he has talked of it. Prince Karl's Operation is likely to be marred amazingly. If this swift King (comparable to the old Serpent for devices) were to burst forth from his Silesian strengths; tread sharply on the TAIL of Prince Karl's Operation, and bring back the formidably fanged head of IT out of Alsace, five hundred miles all at once,--there would be a business!
