Prussia, by a timely declaration of war against France before the battle of Austerlitz, might have turned the tide against Napoleon, and earned for herself the glory and the gain, instead of being, by a false policy, compelled, at a later period, to make that declaration under circumstances of extreme disadvantage. Her maritime commerce suffered extreme injury from the attacks of the English and Swedes. War was unavoidable, either for or against France. The decision was replete with difficulty. Prussia, by continuing to side with France, was exposed to the attacks of England, Sweden, and probably Russia; it was, moreover, to be feared that Napoleon, who had more in view the diminution of the power of Prussia than that of Austria, might delay his aid. During the late campaign, the Prussian territory had been violated and the fortress of Wesel seized by Napoleon, who had also promised the restoration of Hanover to England as a condition of peace. He had invited Prussia to found, besides the Rhenish, a northern confederation, and had, at the same time, bribed Saxony with a promise of the royal dignity, and Hesse with that of the annexation of Fulda, not to enter into alliance with Prussia. Prussia saw herself scorned and betrayed by France. A declaration of war with France was, however, surrounded with tenfold danger. The power of France, unweakened by opposition, had reached an almost irresistible height. Austria, abandoned in every former campaign and hurried to ruin by Prussia, could no longer be reckoned on for aid. The whole of Germany, once in favor of Prussia, now sided with the foe. Honor at length decided. Prussia could no longer endure the scorn of the insolent Frenchman, his desecration of the memory of the great Frederick, or, with an army impatient for action, tamely submit to the insults of both friend and foe. The presence of the Russian czar, Alexander, at Berlin, his visit to the tomb of Frederick the Great, rendered still more popular by an engraving, had a powerful effect upon public opinion. Louisa, the beautiful queen of Prussia and princess of Mecklenburg, animated the people with her words and roused a spirit of chivalry in the army, which still deemed itself invincible. The younger officers were not sparing of their vaunts, and Prince Louis vented his passion by breaking the windows of the minister Haugwitz. John Muller, who, on the overthrow of Austria, had quitted Vienna and had been appointed Prussian historiographer at Berlin, called upon the people, in the preface to the "Trumpet of the Holy War," to take up arms against France.
