Loss of time was one of the losses Frederick could least stand. In visits, even from his brothers and sisters, which were always by his own express invitation, he would say some morning (call it Tuesday morning), You are going on Wednesday, I am sorry to hear (what you never heard before). Alas! your majesty, we must. Well, I am sorry; but I will lay no constraint on you. Pleasant moments can not last forever. This trait is in the anecdote-books; but its authenticity does not rest on that uncertain basis. Singularly enough, it comes to me individually, by two clear stages, from Fredericks sister, the Duchess of Brunswick, who, if any body, would know it well.
ONE: Adieu, my dear Voltaire! May Heaven preserve from misfortune the man I should so like to sup with at night after fighting in the morning. Do not forget the absent who love you.If you then find the prince contrite and humble, you will engage him to fall on his knees with you, to ask pardon of God with tears of penitence. But you must proceed with prudence and circumspection, for the prince is cunning. You will represent to him also, in a proper manner, the error he labors under in believing that some are predestinated to one thing and some to another; and that thus he who is predestinated to evil can do nothing but evil, and he who is predestinated to good can do nothing but good, and that, consequently, we can change nothing of what is to happena dreadful error, especially in what regards our salvation.
Frederick paid but little regard to his allies save as he could make them subservient to the accomplishment of his purposes. He pushed his troops forward many leagues south into Moravia, and occupied the important posts of Troppau, Friedenthal, and Olmütz. These places were seized the latter part of December. The king hoped thus to be able, early in the spring, to carry the war to the gates of Vienna.The Russians marched to Poland. The Austrians returned to Saxony. As soon as Frederick heard of their retreat, instead of continuing his march to Berlin, he also turned his columns southward. On the 27th of October he crossed the Elbe, about sixty miles above Dresden, and found himself in the vicinity of General Daun, whose army outnumbered that of Frederick two to510 one. The situation of Frederick was extremely critical. Under these circumstances, he wrote to DArgens on the 28th:The monarchic, if the king is just and enlightened.
