On the 18th of February, 1730, some affairs of state led the king to take a trip to Dresden to see the King of Poland. He decided to take Fritz with him, as he was afraid to leave him behind. Fritz resolved to avail himself of the opportunity which the journey might offer to attempt his escape. He was unwilling to do this without bidding adieu to his sister, who had been the partner of so many of his griefs. It was not easy to obtain a private interview. On the evening of the 17th of February, as Wilhelmina, aided by her governess, was undressing for bed, the door of the anteroom of her chamber was cautiously opened, and a young gentleman, very splendidly dressed in French costume, entered. Wilhelmina, terrified, uttered a shriek, and endeavored to hide herself behind a screen. Her governess, Madam Sonsfeld, ran into the anteroom to ascertain what such an intrusion meant. The remainder of the story we will give in the words of Wilhelmina: “But she returned the next moment accompanying the cavalier, who was laughing heartily, and whom I recognized for my brother. His dress so altered him he seemed a different person. He was in the best humor possible. ‘I am come to bid you farewell once more, my dear sister,’ said he; ‘and as I know the friendship you have for me, I will not keep you ignorant of my designs. I go, and do not come back. I can not endure the usage I suffer. My patience is driven to an end. It is a favorable opportunity for flinging off that odious yoke. I will glide out of Dresden and get across to England, where, I do not doubt, I shall work out your deliverance too, when I am got thither. So I beg you calm yourself. We shall soon meet again in places where joy shall succeed our tears, and where we shall have the happiness to see ourselves in peace, and free from these persecutions.’” [Illustration: FREDERICK AND HIS SISTER.] Wilhelmina was appalled in view of the difficulty and danger of the enterprise. It was a long distance from Dresden to the coast. Head winds might detain the vessel. The suspicious king would not long remain ignorant that he was missing. He would be pursued with energy almost demoniac. Being captured, no one could tell how fearful would be his doom. The sagacious sister was right. Fritz could not but perceive the strength of her arguments, and gave her his word of honor that he would not attempt, on the present occasion, to effect his flight. Fritz accordingly went to Dresden with his father, and returned. CHAPTER IV. THE ATTEMPT TO ESCAPE.
