The prudent moderation of Abbe de Bernis, then in great favor with Madame de Pompadour, and managing the negotiations with Austria, had removed from the treaty of Versailles the most alarming clauses. The empress and the King of France mutually guaranteed to one another their possessions in Europe, “each of the contracting parties promising the other, in case of need, the assistance of twenty-four thousand men.” Russia and Saxony were soon enlisted in the same alliance; the King of Prussia’s pleasantries, at one time coarse and at another biting, had offended the Czarina Elizabeth and the Elector of Saxony as well as Louis XV. and Madame de Pompadour. The weakest of the allies was the first to experience the miseries of that war so frivolously and gratuitously entered upon, from covetousness, rancor, or weakness, those fertile sources of the bitterest sorrows to humanity.
“It is said that the King of Prussia’s troops are on the march,” wrote the Duke of Luynes in his journal (September 3, 1756); “it is not said whither.” Frederick II. was indeed on the march with his usual promptitude; a few days later, Saxony was invaded, Dresden occupied, and the Elector-king of Poland invested in the camp of Pirna. General Braun, hurrying up with the Austrians to the Saxons’ aid, was attacked by Frederick on the 1st of October, near Lowositz; without being decisive, the battle was, nevertheless, sufficient to hinder the allies from effecting their junction. The Saxons attempted to cut their way through; they were hemmed in and obliged to lay down their arms; the King of Prussia established himself at Dresden, levying upon Saxony enormous military contributions and otherwise treating it as a conquered country. The unlucky elector had taken refuge in Poland.
