Amid the vicissitudes of the revolving centuries the rollicking lords grew poor, and the frugal monks grew rich. A thrifty city rose around the monastery, and its bishop wielded a power, temporal and spiritual, more potent than had ever issued from the walls of the now crumbling and dilapidated castle. In some of the perplexing diplomatic arrangements of those days, the castle of Herstal, with its surrounding district, was transferred to Frederick William of Prussia. The peasants, who had heard of the military rigor of Prussia, where almost every able-bodied man was crowded into the army, were exceedingly troubled by this transfer, and refused to take the oath of allegiance to their new sovereign, who had thus succeeded to the ownership of themselves, their flocks, and their herds. The gleaming sabres of Frederick Williams dragoons soon, however, brought them to terms. Thus compelled to submission, they remained unreconciled and irritated. Upon the withdrawal of the Prussian troops, the authority of Frederick William over the Herstal people also disappeared, for they greatly preferred the milder rule of the Bishop of Liege.
What! cried the queen, have you had the barbarity to kill him?The emperor was probably induced to this decisive course not merely by motives of humanity, but also by the consideration that by thus saving the life of Frederick he would forever attach him to the interests of the house of Austria. The kings of Poland and Sweden also wrote to the king, earnestly interceding for the life of the Crown Prince.On the 26th of April Frederick again wrote to M. Podewils: I can understand how you are getting uneasy at Berlin. I have the most to lose of you all, but I am quiet and prepared for events. If the Saxons take part in the invasion of Silesia, and we beat them, I am determined to plunge into Saxony. For great maladies there need great remedies. Either I will maintain my all or else lose my all. To me remains only to possess myself in patience. If all alliances, resources, and negotiations fail, and all conjunctures go against me, I prefer to perish with honor rather than lead an inglorious life, deprived of all dignity. My ambition whispers me that I have done more than another to the building up of my house, and have played a distinguished part among the crowned heads of Europe. To maintain myself there has become, as it were, a personal duty, which I will fulfill at the expense of my happiness and my life. I have no choice left. I will maintain my power, or it may go to ruin, and the Prussian name be buried under it. If the enemy attempt any thing upon us, we will either beat them, or will all be hewed to pieces for the sake of our country and the renown of Brandenburg. No other counsel can I listen to. Perform faithfully the given work on your side, as I on mine. For the rest, let what you call Providence decide as it likes. I prepare myself for every event. Fortune may be kind or be unkind, it shall neither dishearten me nor uplift me. If I am to perish, let it be with honor, and sword in hand.Still the queen-mother, Sophie Dorothee, clung to the double marriage. Her brother, George II., was now King of England. His son Fred, who had been intended for Wilhelmina, was not a favorite of his fathers, and had not yet been permitted to go to England. In May, 1728, he was twenty-one years of age. He was living idly in Hanover, impatient to wed his cousin Wilhelmina, who was then nineteen years of age. He seems to have secretly contemplated, in conference with Wilhelminas mother, Sophie Dorothee, a trip incognito to Berlin, where he would marry the princess clandestinely, and then leave it with the royal papas to settle the difficulty the best way they could. The plan was not executed. Wilhelmina manifested coquettish indifference to the whole matter. She, however, writes that Queen Sophie was so confidently expecting him that she took every ass or mule for his royal highness.
