The ambassador was now placed in a very delicate position, for the Austrian war had really been a surprise. Napoleon thought himself the dupe of Metternich, and he commanded Fouché, the Minister of Police, to cause him to be seized, and marched from one military station to another, until he reached the frontier. The order was harsh, brutal, and contrary to all diplomatic usages. Is not an ambassador bound to obey the instructions of his government, and to serve its interests? and is it not his duty to conceal every thing that may injure his court? Fouché, with his usual regard to his own interest, and who considered what the future might bring forth, executed the orders of Napoleon with delicacy and politeness. He went to the ambassador's house, told him the occasion of his visit, and expressed the most lively regret for it. A degree of dissatisfaction had already begun to arise in the mind of this minister, who looked forward to the time when the insatiable ambition of Napoleon must have a limit, and he and Metternich expressed to each other, in mutual confidence, their feelings on the miseries of war and the rapacious spirit of Napoleon; and Fouché, whose disposition was generally communicative and incautious, went so far as to give utterance to most singular opinions concerning the probable downfall, or even death, of his master. In order as far as possible to soften the rigorous orders he had received, a single captain of gendarmerie, chosen by Marshal Moncey, accompanied the travelling-carriage of the ambassador to the frontier. Prince Metternich takes pleasure in relating the curious occurrences of this journey, which, like that of the aide-de-camp Czernicheff in 1812, was not devoid of peril. Then the earth was shaken! The Austrian army, under the Archduke Charles, fought valiantly for the defence of their country and their sovereign, and the battle of Essling menaced the fortunes of Napoleon. The disastrous event of this day was never fully published in France; but elsewhere it was perfectly known. Preussisch-Eylau, the capitulation of Baylen, and the battle of Essling on the Danube, appear to me to be the three culminating points, which first taught the world that the armies of Napoleon were no longer invincible: these battles had a great moral influence upon the affairs of Europe, and Wagram was necessary to restore the powerful effect of the Emperor's name; the field of battle on this occasion was doubtful, but nothing could be more decisive than the result; great discouragement was manifested in the councils of Vienna, and the party in favour of peace carried the day.
