FORE:General Daun, with the utmost caution, followed the retreating army. Though his numbers were estimated at seventy-five thousand, he did not dare to encounter Frederick with his thirty thousand Prussians on the field of battle. With skill which has elicited the applause of all military critics, Frederick, early in August, continued his retreat till he reached, on the 8th of the month, Grüssau, on his own side of the mountains in Silesia. On this march he wrote to his brother Henry from Skalitz:Voltaires visit lasted about thirty-two months. He was, however, during all this time, fast losing favor with the king. Instead of being received as an inmate at Sans Souci, he was assigned to a small country house in the vicinity, called the Marquisat. His wants were, however, all abundantly provided for at the expense of the king. It is evident from his letters that he was a very unhappy man. He was infirm in health, irascible, discontented, crabbed; suspecting every one of being his enemy, jealous of his companions, and with a diseased mind, crowded with superstitious fears.
