Accordingly it is now well understood, that the first impulse of the King of Prussia's mind was to throw himself into the arms of Russia, and offer, should it cost him his life and crown, to take share in the war as his faithful ally. But the Emperor Alexander was sensible that, in accepting this offered devotion, he would come under an obligation to protect Prussia in case of those reverses, which might be almost reckoned on as likely to occur in the early part of the campaign. The strongest fortresses in Prussia were in the hands of the French, the army of the King did not amount to more than 40,000 men, and there was no time to arm or organise the national forces. In order to form a junction with these 40,000 men, or as many of them as could be collected, it would be necessary that Alexander should precipitate the war, and march a strong army into Silesia, upon which the Prussians might rally. But such an army, when it had attained its object, must have had in front the whole forces of France, Saxony, and the Confederacy of the Rhine, while the hostile troops of the grand duchy of Warsaw, with probably a body of Austrian auxiliaries, would have been in their rear. This premature movement in advance, would have resembled the conduct of Austria in the unhappy campaigns of 1805 and 1809; in both of which she precipitated her armies into Bavaria, in hopes of acquiring allies, but only exposed them to the decisive defeats of Ulm and Eckmühl. It would also have been like the equally ill-omened advance of the Prussian army in 1806, when hurrying forward to compel Saxony to join him, the Duke of Brunswick gave occasion to the unhappy battle of Jena.
