The battle of Zorndorf was the most bloody of the Seven Years War. It is often considered the most furious battle which was ever fought. While Frederick was engaged in this arduous campaign in the extreme north, driving the Russians from the Prussian territory, an Austrian army, ninety thousand strong, under General Daun, was endeavoring to reconquer Saxony. The Prussian king had left his brother Henry in defense of the province, with a small force garrisoned in the city of Dresden.
And all that I have been relating to you is due to the king alone, who not only gave the orders, but himself saw that they were faithfully obeyed. He both conceived the designs and executed them. He spared neither care, nor trouble, nor vast treasures, nor promises, nor recompenses, in order to assure the existence and the comfort of half a million of rational beings, who owe to him alone their happiness. There is something in my mind so heroic in the generous and laborious manner in which the king has devoted himself to the restoring to this deserted country its population, fertility, and happiness, that I think you will see his conduct in the same light as I do when you are made acquainted with the circumstances.
Then addressing Grumkow, she said, in tones deliberate and76 intense, For you, sir, who are the author of my misfortunes, may my curse fall upon you and your house. You have this day killed me. But I doubt not that Heaven will hear my prayer and avenge my wrongs.Soon after Frederick wrote to Voltaire upon this subject again, still more severely, but in verse. The following is almost a literal translation of this poetic epistle:It is perhaps not strange that Frederick should have imbibed a strong feeling of antipathy to Christianity. In his fathers life he had witnessed only its most repulsive caricature. While making the loudest protestations of piety, Frederick William, in his daily conduct, had manifested mainly only every thing that is hateful and of bad report. Still, it is quite evident that Frederick was not blind to the distinction between the principles of Christianity as taught by Jesus and developed in his life, and the conduct of those who, professing his name, trampled those principles beneath their feet. In one of his letters to Voltaire, dated Cirey, August 26, 1736, Frederick wrote:In fine, my dear marquis, the job ahead of me is hard and difficult, and nobody can say positively how it will all go. Pray for us; and dont forget a poor devil who kicks about strangely in his harness, who leads the life of one damned.
