At these reviews, the commanders of regiments were subjected to a rigourous cross-examination by the Emperor, particularly on the eve of a campaign; for apart from the usual questions about their strength in men and horses, their arms etc., he would suddenly ask a number which were unforeseen and not always easy to answer. For example: "How many men from such and such a department have you received in the last two years? How many of your carbines come from Tulle and how many from Charleville? How many of your horses are from Normandy, from Brittany, from Germany? What is the average age of your men, your officers, your horses? How many men in this company have long-service chevrons? etc…etc."

These questions, which were always posed in an abrupt and demanding manner, and accompanied by a piercing look, disconcerted many colonels; but woe to him who hesitated to reply, he went into Napoleon's bad books. I was so well briefed that I was able to reply to all his questions, and, after complementing me on the fine turnout of the regiment, it looked as if the Emperor was going to promote me to colonel and M. de La Nougarede to general, when the latter, who with his limbs wrapped in flannel, had been hoisted onto horseback to follow from afar the movements of his regiment, which I commanded, hearing himself called for, came to Napoleon and unwisely angered him by making a request on behalf of an officer, a member of his family who was wholly undeserving. This roused a storm of which I suffered the consequences. The Emperor flew into a rage and ordered the Gendarmerie to clear the officer in question out of the army, and leaving M. de La Nougarede in dismay, he went off at the gallop. So M. de La Nougarede was not made a general.

Marshal Oudinot followed the Emperor to find out what was to happen to the 23rd, and was told "Major Marbot will continue to command them." Before reaching the rank of colonel I was destined to suffer yet another serious wound.

In fairness to M. de La Nougarede, I have to say that he expressed the liveliest remorse at having been the involuntary cause of the delay in my advancement. I was sorry for the difficult position in which this worthy man found himself, for he felt that he had forfeited the Emperor's confidence, and owing to his disability he had little hope of restoring himself by his conduct in the battles which were about to take place.

I was comforted by the fact that the Emperor, on the day of the review, had awarded all the promotions and the decorations which I had requested for the officers and other ranks of the 23rd, and as the gratitude for these favours is always directed to the commanding officer who has obtained them, the influence which I was beginning to have in the regiment was greatly increased and went some way to calm my regrets at not having been awarded substantive rank for the position which I occupied.

At about this time, I received a letter from Marshal Massena and another from his wife, the first recommending a M. Renique, and the second her son, Prosper. I was touched by this double approach and I responded by accepting the two captains into my regiment. However, Madame Massena did not carry out her intention, and Prosper Massena did not go to Russia. In any case he would not have been able to stand the harsh climate.

The army was soon to reach the frontier of the Russian empire, and see once more the river Nieman, where we had stopped in 1807. The Emperor positioned his troops on the left bank of this river as follows: on the extreme right was the Austrian Corps of Prince Schwartzenberg, on the border of Galicia near Drogitchin. On Schwartzenberg's left was King Jerome with two considerable army corps, between Bialystok and Grodno. Next to them was Prince Eugene de Beauharnais, with 80,000 men, at Prenn. The Emperor was in the centre, facing Kovno, with 220,000 men commanded by Murat, Oudinot, Ney, Lefebvre and Bessieres. The Guard formed part of this immense body of troops. Finally, at Tilsit, Marshal Macdonald with 35,000 Prussians formed the left wing. Across the Nieman was the Russian army of about 400,000 men, commanded by the Emperor Alexander , or rather by Benningsen, his chief-of-staff. This force was divided into three parts, commanded by Generals Bagration, Barclay de Tolly and Wittgenstein.

Four historians have written about the campaign of 1812. The first of these was Labaume, a topographer, that is to say, belonging to a Corps which although part of the armed forces never engaged in combat, and followed the army only to make maps. Labaume had never commanded troops and knew nothing of the practical side of war, so his judgements are almost always ill-founded, and do an injustice to the French army. However the work having appeared shortly after the peace of 1814 and the re-establishment of Louis XVIII, partisan spirit and the desire for information about the terrible events of the Russian campaign gave it so much credence that no one tried to refute it, and the public came to accept its contents as the veritable truth.

The second book to be published was written by Colonel Boutourlin, an aide-de-camp to the Emperor Alexander. This, although expressing the Russian point of view, contained some worthwhile observations, and if there are some inaccuracies, it is because he did not have access to certain documents, for he is impartial and has done all he could to discover the truth. The work is generally esteemed as that of an honest man.

Labaume's book had already been forgotten when in 1825, following Napoleon's death, General de Segur published a third story of the Russian campaign. The contents of this book distressed more than one survivor of the campaign, and even the Russians stigmatised it as a war novel. In spite of this, M. de Segur enjoyed a great success, partly because of the purity and elegance of his style and partly because of the welcome the book was given by the court and the ultra-royalist party. The former officers of the imperial army, finding themselves under attack, appointed General Gourgaud to reply. He did so effectively, but with so much acerbity that it gave rise to a duel between him and M. de Segur, in which M. de Segur was wounded. One has to agree that if the latter was less than charitable towards Napoleon and his army, General Gourgaud accorded the Emperor too much praise and refused to recognise any of his faults.
