During our stay at Ulm, the Prussians suddenly conceived the idea that they had an ancient inheritance of glory to defend. They were roused, and they took up arms. Haugwitz came to inform us of this sudden reminiscence. But the battle of Austerlitz had taken place in the interim. When the Minister arrived, nothing was thought of but alliance and devotion. Napoleon was not the dupe of these diplomatic protestations: he was aware of the intrigues and the chivalric scenes that had been resorted to for the purpose of exciting the multitude. Previous to the action he had said; "If I am beaten, they will march upon my rear; if I am victorious, they will say that they wished to have taken part with me." They knew not how to make choice either of peace or war; and they watched the progress of events. This indirect policy was not without its effect; it cost them Anspach, Bareuth, a part of the grand duchy of Berg, and their possessions in Westphalia. They became enraged. I was sent to Hanover, which we had abandoned to them. The ostensible motive of my journey was the delivering up of the fortress of Hameln; its real purpose was to learn the state of the public mind. I was directed to discover what was the general opinion with regard to the Prussians, whether war was spoken of, whether the army wished for it, and finally, to buy up at Hamburgh all the pamphlets against Napoleon and France which I could procure.

My mission was not difficult of execution. The Prussians were exasperated and insolent; the Hanoverians detested them. The north of Germany, however, relied on Prussia, whose power remained undiminished. The Count of Schulemburgh was governor of King William's new acquisition: he gave me rather a cold reception. Our success at Ulm and Austerlitz appeared to him but indifferent. The latter battle he affirmed was indecisive. He said it was like the battle of Zorndoff, which was fought by Frederick the Great against the Russians, and in which Count Schulemburgh had himself been engaged. "What sort of victories would he have?" said the Emperor, when I told him this anecdote.

I went from Hanover to Hamburgh, where I found Bourienne. Here I was well received, and I knew the reason why.

I returned to France, and on my way passed through Munster, where I saw General Blucher, whom I had known some years before. I paid him a visit. He was not well disposed towards the French; yet he received me with a great deal of civility.

I remained a week with Augereau at Frankfort, in order to see and hear all I could; for such were my instructions. Napoleon had just made a demand for contributions on that town, and the inhabitants were alarmed lest they should be obliged to pay them.

We occupied Darmstadt. Marshal * * * * * * *, who had established his head-quarters in the capital of that principality, was neither a favourite with the Court nor with the people; and his staff was still less liked. The Grand Duchess sent me an invitation, through Augereau, who seemed to be partial to that country; I declined it, not having any instructions to that effect. She commissioned him to transmit to me her complaints. They were very severe.

I departed for Wesel. I was to examine the state of feeling in that quarter, which was already occupied by our troops.

On my return, I gave Napoleon an account of all that I had seen and heard. I concealed nothing from him. I spoke particularly in behalf of Darmstadt; but he was enraged against the Duchess. She had written a terrible letter to the King of Bavaria, relative to what she termed the ill-assorted union of her niece Augusta with Prince EugÈne. Among other insulting expressions she made use of the words horrible marriage. The Emperor, who conceived that the glory of having achieved great deeds was well worth the advantage of having descended from those who probably had no glory to boast of, could not pardon the feudal prejudices of the Duchess. He was on the point of depriving her of her states; but Maximilian interceded for her, and she escaped with the punishment of a six months' occupation by our troops; that is to say, her people were obliged to atone for the offence which her vanity had led her to commit.

Scarcely a fortnight had elapsed since my return to France. The Court was at Saint-Cloud, and Napoleon was at the theatre. In the middle of the performance he received a despatch from the Grand Duchy of Berg. He opened it. It contained an account of an attack made on our troops by some Prussian detachments. "I see," said he, "they are determined to try us. Mount your horse and seek the Grand Duke at Neuilly." Murat was already acquainted with the affair; he came immediately. Napoleon conversed with him for an instant, and gave me orders next day to take the command of the military division at Strasburg; to organise battalions and marching squadrons at that place; to direct them in succession upon Mentz, and to send to the latter place a large quantity of artillery. The infantry embarked on the Rhine in order to arrive earlier at the place of their destination.

I corresponded directly with Napoleon. I employed couriers, telegraphs, and all the most speedy modes of communication. I could not venture to put a hundred men in motion, to change the place of a gun, or to move a musquet, without informing him. I had been two months engaged in these preparations, when he arrived at Mentz, whence he wrote to me to join him at Wurtzburg. He sent me a letter for the Grand Duke of Baden, and directed me to deliver it to the Prince myself. The object of this letter was to request him to send his grandson, the present Grand Duke, to the army. I found the venerable old man in his ancient castle of Baden; he seemed at first much affected by the contents of the letter; but he soon made up his mind to send the young Prince, and he ordered preparations for his departure. He did me the honour to recommend his grandson to me in a very affectionate manner. The Prince set out on his journey two days afterwards, and joined us at Wurtzburg. The King of Wirtemberg was already there. He had just determined on his daughter's marriage with Jerome. Napoleon was in particularly good humour. The alliance pleased him. He was no less satisfied with the Grand Duke; for Murat had singularly prepossessed him in favour of that Prince. In a letter which Murat addressed to the Emperor some days before, he said;—"I waited on the Grand Duke of Wurtzburg, whom the letter, and the news which I communicated to him, that the treaty admitting him into the confederation had been signed at Paris, have relieved from the greatest anxiety; for he very much dreaded not being received into the Confederation. He seemed particularly affected by the sentiments of good will on the part of your Majesty which I expressed to him. He evinces the greatest readiness to contribute every thing in his power to the service of the army. To-day his admission into the Confederation of the Rhine was proclaimed. Every preparation has been made for receiving your Majesty at the Castle, where nothing seems to be neglected which may render your stay here convenient and agreeable."

We had yet received no positive information with regard to the Prussians; we knew not whether they were on the road to Magdeburg, in Saxony, or at Gotha; or even what was the amount of their force. We had, however, a sufficient number in the field. Gentlemen are not more scarce on the other side of the Rhine than elsewhere: but the reports were so contradictory, that it was impossible to form any distinct idea on the subject. At one time it was said that the enemy's advance-guard was at Hoff; that Coburg and Memmingen were occupied; that the Prussians avoided partial actions, and wished to try their fortune in a pitched battle. At another time it was affirmed that Hohenlohe was advancing on Schleitz; that Ruchel had formed his junction; that the Queen had gone to Erfurt; and that the head-quarters were removed from Hoff to Nauenburgh. This arrangement did not correspond with the nature of the places. It seemed inconceivable. We were as uncertain with respect to the extent of the enemy's forces as we were concerning their line of operations. Amidst all these various accounts we learnt that Cronach was occupied. The Grand Duke sent to inform us, that that citadel was under repair, and would soon be in a state of defence. Napoleon was astonished that the Prussians had not made themselves masters of it. "What could have prevented them," said he, "since they absolutely wanted war? Was it the difficulty of the attempt?—The place was destitute both of provisions and artillery. They had sufficient courage for the enterprize. Did they not consider the place of sufficient importance to try to secure it? That fort commands three great outlets; but these gentlemen care little about positions, they are reserving themselves for grand strokes; we will give them what they want."

Napoleon every moment received accounts of the Prussian army. Ruchel, Blucher, and the Duke of Brunswick, were impatient to commence the war, and Prince Louis was even more so. He urged and hastened hostilities, and feared to let the opportunity escape. He was, besides, a man of great courage and talent; all accounts agreed on this point. Napoleon, who did not dislike this petulant eagerness, was conversing with us one evening respecting the generals of the enemy's army. Some one present happened to mention Prince Louis. "As for him," said he, "I foretell that he will be killed this campaign." Who could have thought that the prediction would so soon have been fulfilled?

Prussia at length explained herself. She required us to abandon our conquests, and threatened us with her displeasure if we refused to evacuate Germany and recross the Rhine. The demand was modest, and worthy of those who urged it. Napoleon could not finish reading the document; he threw it away contemptuously. "Does he think himself in Champagne?" said he. "Does he want to give us a new edition of his manifesto? What! does he pretend to mark out a route for our march back. Really, I pity Prussia, I feel for William. He is not aware what rhapsodies he is made to write. This is too ridiculous. Berthier, they wish to give us a rendezvous of honour for the 8th; a beauteous Queen will be a witness to the combat. Come, let us march on; and shew our courtesy. We will not halt till we enter Saxony." Then turning immediately to his secretary, he hastily dictated the following proclamation:

Our soldiers only wished to fight. The Prussians occupied Saalfeld and Schleitz; we charged them, routed them, and made a thousand prisoners. These were the two first engagements which we had with them. I quitted Murat, whom I had been ordered to follow, and went to render an account of the affair of Schleitz to Napoleon, who had established his head-quarters some leagues in the rear, at the residence of a Princess of Reus-Lobenstein. On my arrival I found Napoleon engaged with Berthier. I informed him of the success of the Grand Duke, and of the defeat of Tauenzien. "Tauenzien!" exclaimed Napoleon, "one of the Prussian intriguers! It was well worth our while to urge on the war to such a length." He told me I might retire and take some rest, as I should be roused in a few hours to set out on a mission. I had no idea whither I was to go. I was called about 5 o'clock. The Emperor gave me a letter for King William, who at that time, I believe, held his head-quarters at Sondershausen. "You must go," said he, "as fast as you can after the King of Prussia, and deliver to him this letter from me. I ask him once more for peace, though hostilities have already commenced. You must endeavour to convince the King of the danger of his situation, and the fatal consequences which may result from it. You will return immediately and bring me his answer: I shall now march on Gera." Our baggage was still in the rear. I had no carriage; but I procured one from the coach-house of the Princess of Reus-Lobenstein, put four good horses to it, and started about six o'clock. Before I had proceeded a league on my journey, Napoleon sent after me. I returned and went to his study, where he had been occupied the whole of the night. He desired me to deliver the letter to Berthier. "Upon reflection," said he, "I will not have one of my aides-de-camp charged with such a message. You are persons of too great importance to be exposed to the chance of meeting with a bad reception." The letter was sent two days after by M. de Montesquiou: he started, I believe, from Gera. The treatment he experienced is well known: he was stopped by the Prince de Hohenlohe, at that time general-in-chief of the Prussian army, who obliged him to be present at the battle of Jena, and did not send the letter, as it is affirmed, until after the action.

Several persons in Napoleon's suite were of opinion, that if I had executed the commission with which I was at first charged, I should have come up with the King of Prussia, and the war perhaps would not have taken place. I do not think so. The gauntlet was thrown, there was no alternative but to take it up. I do not even think that Napoleon was more inclined for peace than King William.
