As Frederick received the tidings of this death, he rose, dressed himself, and his ague disappeared, to return no more. A courier was immediately dispatched, at the top of his speed, to summon to his presence General Schwerin and M. Podewils, his chief minister. Two days must elapse before they could reach him. In the mean time, the king, taking counsel of no one, was maturing his plans, and making quiet but vigorous preparations for their execution. He wrote the next day to Voltaire, in allusion to the emperors death,FREDERICK WILLIAM.475 During this dismal winter of incessant and almost despairing labor the indefatigable king wrote several striking treatises on military affairs. It is manifest that serious thoughts at times occupied his mind. He doubtless reflected that if there were a God who took any cognizance of human affairs, there must be somewhere responsibility to Him for the woes with which these wars were desolating humanity. To the surprise of De Catt, the king presented him one evening with a sermon upon The Last Judgment, from his own pen. He also put upon paper his thoughts On the new kind of tactics necessary with the Austrians and their allies. He seems himself to have been surprised that he had been able so long to resist such overpowering numbers. In allusion to the allies he writes:Frederick on the 17th, the day after the departure of the Austrian army, invested Neisse. He had an embarrassing part to play. He was to conduct a sham siege in the presence of M. Valori, who was not only a man of ability, but who possessed much military intelligence. Feigning the utmost zeal, Frederick opened his trenches, and ostentatiously man?uvred his troops. He sent the young Prince Leopold, with fifteen thousand horse and foot, into the Glatz country, many leagues to the east, to guard against surprise from an enemy, where no enemy was to be found. He marked out his parallels, sent imperious summonses for surrender, and dispatched reconnoitring parties abroad. M. Valori began to be surprisedamazed. What does all this mean? he said to himself. They have great need of some good engineers here.
