The prince supposed that the object of Muller’s visits was to prepare him for his death. But upon receiving the full assurance that his father contemplated pardoning him, should there be evidence of repentance, he promised to take an oath of entire submission to his father’s will. Seven commissioners were sent to the prison of Cüstrin, on the 19th of November, to administer this oath with the utmost solemnity. He was conducted to the church. A large crowd was in attendance. A sermon appropriate to the occasion was preached. The sacrament of the Lord’s Supper was administered to him. And then he audibly repeated the oath and attached to it his signature. From the church the prince was conducted, not back to his prison in the fortress, but to a town mansion, which was assigned as his residence. His sword was restored to him. But he was still not fully liberated. Officials, appointed by his father, surrounded him, who watched and reported all his movements. The first act of the young prince, upon reaching his apartment after this partial liberation, was to write as follows to his father. We give the letter as translated by Carlyle: “Cüstrin, November 19, 1730. “ALL-SERENEST AND ALL-GRACIOUSEST FATHER,--To your royal majesty, my all-graciousest Father, I have, by my disobedience as Their subject and soldier, not less than by my undutifulness as Their son, given occasion to a just wrath and aversion against me. With the all-obedientest respect I submit myself wholly to the grace of my most All-gracious Father, and beg him most All-graciously to pardon me, as it is not so much the withdrawal of my liberty, in a sad arrest, as my own thoughts of the fault I have committed that have brought me to reason, who, with all-obedientest respect and submission, continue till my end my All-graciousest king’s and Father’s faithfully-obedientest servant and son, FREDERICK.” Here, in the little town of Cüstrin, in a house very meagerly furnished, the Crown Prince established his household upon the humblest scale. The prince was allowed to wear his sword, but not his uniform. He was debarred all amusements, and was forbidden to read, write, or speak French. To give him employment, he was ordered to attend regularly the sittings of the Chamber of Counselors of that district, though he was to take his seat as the youngest member. Three persons were appointed constantly to watch over him. Lord Dover writes: “His diet was regulated at a sum which made it barely sufficient to prevent actual starvation. His apartment was most miserable, and almost entirely devoid of furniture. He was in great want of linen, and of others of the first necessaries of life. At nine o’clock at night his candle was taken from him, while pen, ink, paper, and books were alike denied him.”
