THREE: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.

Some two hundred miles south of Brandenburg there was, at that time, a small marquisate called Anspach, next in dignity to a dukedom. The marquis was a frail, commonplace boy of seventeen, under the care of a young mother, who was widowed, sick, and dying. Much to the dissatisfaction of Sophie Dorothee, the queen-mother, Frederick William had arranged a marriage between this young man, who was far from rich, and his second daughter, Frederica Louisa, who was then fifteen years of age.7
