Napoleon, however, dissembled his displeasure; for he had his army to re-organize, to give the grand duchy of Berg to Murat, his brother-in-law, Neufchatel to Berthier, to conquer Naples for his brother Joseph, to mediatize Switzerland, to dissolve the Germanic body, and to create the Rhenish confederation, of which he declared himself protector; to change the republic of Holland into a kingdom, and to give it to his brother Louis.  These were the reasons which induced him, on the 15th of December, to cede Hanover to Prussia, in exchange for Anspach, Cleves, and Neufchatel.

The possession of Hanover at first tempted Frederick, but when the treaty was to be signed, he appeared to feel ashamed, and to hesitate; he wished only to accept it by halves, and to retain it merely as a deposit.  Napoleon had no idea of such timid policy.  “What!” said he, “does this monarch dare neither to make peace nor war?  Does he prefer the English to me?  Is there another coalition preparing?  Does he despise my alliance?” Indignant at the idea, by a fresh treaty, on the 8th of March, 1806, he compelled Frederick to declare war against England, to take possession of Hanover, and to admit French garrisons into Wesel and Hameln.

The king of Prussia alone submitted; his court and his subjects were exasperated; they reproached him with allowing himself to be vanquished without attempting to fight; and elevating themselves on the remembrance of their past glory, they fancied that for them alone was reserved the honour of triumphing over the conqueror of Europe.  In their impatience they insulted the minister of Napoleon; they sharpened their swords on the threshold of his gate.  Napoleon himself they loaded with abuse.  Even the queen, so distinguished by her graces and attractions, put on a warlike attitude.  Their princes, one of them particularly (whose carriage and features, spirit and intrepidity, seemed to promise them a hero), offered to be their leaders.  A chivalrous ardour and fury animated the minds of all.

It is asserted, that at the same time there were persons, either treacherous or deceived, who persuaded Frederick that Napoleon was obliged to show himself pacific, that that warrior was averse to war; they added, that he was perfidiously treating for peace with England, on the terms of restoring Hanover, which he was to take back from Prussia.  Drawn in at last by the general feeling, the king allowed all these passions to burst forth.  His army advanced, and threatened Napoleon; fifteen days afterwards he had neither army nor kingdom; he fled alone; and Napoleon dated from Berlin his decrees against England.
