The unfortunate King of Prussia was invited to appear at Tilsit; but, complying with this invitation, was admitted to no share of the intimacy of Napoleon. The conqueror studiously, and on every occasion, marked the difference between his sentiments respecting this prince and the young and powerful sovereign, for whose sake alone any shadow of royalty was to be conceded to the fallen house of Brandenburg. The beautiful and fascinating queen also arrived at Tilsit; but she was treated even more coldly and harshly than her husband. Involuntary tears rushed from her eyes as she submitted to the contemptuous civilities of Napoleon. His behaviour to this admirable person rekindled with new fervour the wrath and hatred of every Prussian bosom; and her death, following soon afterwards, and universally attributed to the cruel laceration which all her feelings as a woman and a queen had undergone, was treasured as a last injury, demanding, at whatever hazard, a terrible expiation.
The Treaty of Tilsit, to which, as the document itself bore testimony, the King of Prussia was admitted as a party solely by reason of Napoleon’s “esteem for the Emperor of Russia,” was ratified on the 7th July. Napoleon restored, by this act, to Frederick William, Ancient Prussia, and the French conquests in Upper Saxony—the King agreeing to adopt “the continental system,” in other words, to be henceforth the vassal of the conqueror. The Polish provinces of Prussia were erected into a separate principality, styled “the Grand Duchy of Warsaw,” and bestowed on the Elector of Saxony; with the exception, however, of some territories assigned to Russia, and of Dantzick, which was declared a free city, to be garrisoned by French troops until the ratification of a maritime peace. The Prussian dominions in Lower Saxony and on the Rhine, with Hanover, Hesse-Cassel, and various other small states, formed a new kingdom of Westphalia, of which Jerome Buonaparte, Napoleon’s youngest brother, was recognised as King; Jerome having at length made his peace with his brother by repudiating his wife, an American lady of the name of Patterson, and consenting to a new alliance, more consonant with the views of the Emperor, with a daughter of the King of Wirtemberg. The Elector of Saxony was recognised as another King of Napoleon’s creation; Joseph Buonaparte as King of Naples; and Louis, of Holland. Finally, Russia accepted the mediation of France for a peace with Turkey, and France that of Russia for a peace with England.
