This was at length managed through the instrumentality of a Baron Wrech, whose family lived in the neighborhood, and who, at considerable risk as well as expense, furnished him with books, music, and other comforts. By degrees he so gained upon his gaoler, that he was permitted, under cover of the night, to visit at the Baron’s residence; and as the young Wrechs were sprightly and accomplished, as well as anxious to serve him, they got up little concerts for his amusement. In this way, for upwards of a year, his imprisonment was greatly ameliorated. The old king at last relented, and Frederick obtained his liberty; but it was only on the special condition that he married Elizabeth Christina, a princess of the house of Brunswick. This forced marriage proved utterly abortive of the object intended by the tyrannical old match-maker, for Frederick never lived with the princess, although, through life, he treated her with the greatest respect. She was a woman of meritorious conduct, but quite destitute of personal attractions. Frederick’s marriage took place in 1732, and from that time till the death of his father in 1740, he resided at Rheinsberg, a village some leagues from Berlin. During this interval of eight years, he devoted himself chiefly to literary pursuits, and wrote his _Anti-Machiavel_, and _Reflections on the Character of Charles XII._ The social circle with which he was connected at this time, consisted mostly of learned and ingenious Frenchmen, and probably that circumstance contributed to imbue him with the strong predilection which he ever afterwards displayed in favor of everything French. His accession to the throne in 1740, brought at once into action the whole energies of his character. He himself entered personally upon all the duties, usually committed by kings to their ministers; and in order to accomplish the multiplicity of business which thus devolved upon him, he laid down strict rules for the appropriation of his time, to which he ever afterwards scrupulously adhered. He rose regularly at four in the morning, occupying but a few minutes with his dress, of which, however, he was careless even to slovenliness; and this practice he continued till a late period of his life. The details of a peaceful administration were, however, found quite inadequate to the activity of his mind. Accordingly, in the first year of his reign, he resolved on war; but, unfortunately for his character, it was a war of aggression--a war, too, against a female, and the heir of the very house which had saved him from the scaffold. He resolved to wrest Silesia from Maria Theresa, of Austria, and in less than two years he accomplished this object, the province being ceded to him by the treaty of Breslaw, in 1742. It has ever since continued to form a part of the Prussian dominions.
