Five days after this letter was written to Voltaire by Wilhelmina from Baireuth, Frederick, on the 17th of September, 1757, wrote his sister from near Erfurt. This letter, somewhat abbreviated, was as follows:
Battle of Hohenfriedberg.Religious Antagonism.Anecdote of the King.Retreat of the Austrians.Horrors of War.A slight Pleasantry.Sufferings of the Prussian Army.The Victory of Fontenoy.Fredericks Pecuniary Embarrassments.Executive Abilities of Maria Theresa.Inflexibility of the Austrian Queen.The Retreat to Silesia.The Surprise at Sohr.Military Genius of Frederick.Great Victory of Sohr.A new career came to open itself to me. And one must have been either without address or buried in stupidity not to have profited by an opportunity so advantageous. I seized this unexpected opportunity by the forelock. By dint of negotiating and intriguing, I succeeded in indemnifying our monarchy for its past losses by incorporating Polish Prussia with my old provinces. This acquisition was one of the most important we could make, because it joined Pommern to East Prussia, and because, rendering us masters of the Weichsel River, we gained the double advantage of being able to defend that kingdom (East Prussia), and to draw considerable tolls from the Weichsel, as all the trade of Poland goes by that river.
ONE:In the mean time, during the two years in which Maria Theresa was making these conquests, Frederick, alarmed by the aggrandizement of Austria and the weakening of France, while unavailingly striving to promote peace, was busily employed in the administration of his internal affairs. He encouraged letters; devoted much attention to the Academy of Arts and Sciences; reared the most beautiful opera-house in Europe; devoted large sums to secure the finest musicians and the most exquisite ballet-dancers which Europe could afford. He sought to make his capital attractive to all those throughout Europe who were inspired by a thirst for knowledge, or who were in the pursuit of pleasure.ASSASSINATION OF PETER III.
The thought alone, he wrote, of your death, my dear Suhm, affords me an argument in proof of the immortality of the soul. For is it possible that the spirit which acts in you with so much clearness, brightness, and intelligence, which is so different from matter and from bodythat fine soul endowed with so many solid virtues and agreeable qualitiesis it possible that this should not be immortal? No! I would maintain in solid argument that, if the greatest part of the world were to be annihilated,426 you, Voltaire, Boileau, Newton, Wolfius, and some other geniuses of this order must be immortal.107 My dearest Sister,I have the satisfaction to inform you that we have yesterday53 totally beaten the Austrians. They263 have lost more than five thousand men in killed, wounded, and prisoners. We have lost Prince Frederick, brother of Margraf Karl; General Schulenberg, Wartensleben of the Carabineers, and many other officers. Our troops did miracles, and the result shows as much. It was one of the rudest battles fought within the memory of man.On quitting me he said, I hope, sir, you will leave me your name. I am very glad to have made your acquaintance. Perhaps we shall see one another again. I replied as was fitting to the compliment, and begged him to excuse me for having contradicted him a little. I then told him my name, and we parted.
