The emperor only arrived on the field of battle at nightfall, escorted by a very feeble detachment. He advanced towards Mojaisk, at a still slower pace than the day before, and so completely absent, that he neither seemed to hear the noise of the engagement, nor that of the bullets which were whistling around him.

Some one stopped him, and pointed out to him the enemy's rear-guard between him and the town; and on the heights behind, the fires of an army of 50,000 men. This sight was a proof of the incompleteness of his victory, and how little the enemy were discouraged; but he seemed quite insensible of it; he listened to the reports with a dejected and listless air, and returned to sleep at a village some little distance off, which was within reach of the enemy's fire.

The Russian autumn had triumphed over him: had it not been for that, perhaps the whole of Russia would have yielded to our arms on the plains of the Moskwa: its premature inclemency was a most seasonable assistance to their empire. It was on the 6th of September, the very day before the great battle! that a hurricane announced its fatal commencement. It struck Napoleon. Ever since the night of that day, it has been seen that a wearying fever had dried up his blood, and oppressed his spirits, and that he was quite overcome by it during the battle; the suffering he endured from this, added to another still more severe, for the five following days arrested his march, and bound up his genius. This it was which preserved Kutusof from total ruin at Borodino, and allowed him time to rally the remainder of his army, and withdraw it from our pursuit.

On the 9th of September we found Mojaisk uncovered, and still standing: but beyond it the enemy's rear-guard on the heights which command it, and which their army had occupied the day before. Some of our troops entered the town for the purpose of passing through it in pursuit of the enemy, and others to plunder and find lodgings for themselves. They found neither inhabitants nor provisions, but merely dead bodies, which they were obliged to throw out of the windows, in order to get themselves under cover, and a number of dying soldiers, who were all collected into one spot. These last were so numerous, and had been so scattered about, that the Russians had not dared to set fire to the habitations; but their humanity, which was not always so scrupulous, had given way to the desire of firing on the first French they saw enter, which they did with shells: the consequence was, that this wooden town was soon set fire to, and a part of the unfortunate wounded whom they had abandoned were consumed in the flames.

While we were making attempts to save them, fifty voltigeurs of the 33d climbed the heights, of which the enemy's cavalry and artillery still occupied the summit. The French army, which had halted under the walls of Mojaisk, was surprised at seeing this handful of men, scattered about on this uncovered declivity, teasing with their fire thousands of the enemy's cavalry. All at once what had been foreseen happened; several of the enemy's squadrons put themselves in motion, and in an instant surrounded these bold fellows, who immediately formed, and kept facing and firing at them in all directions; but they were so few in the midst of a large plain, and the number of cavalry about them was so great, that they soon disappeared from our eyes. A general exclamation of sorrow burst from the whole of our lines. Every one of the soldiers with his neck stretched, and his eye fixed, followed the enemy's movements, and endeavoured to distinguish the fate of his companions in arms. Some were lamenting the distance they were at, and wishing to march; others mechanically loaded their muskets or crossed their bayonets with a threatening air, as if they had been near enough to assist them. Their looks were sometimes as animated as if they were fighting, and at other times as much distressed as if they had been beat. Others advised and encouraged them, forgetting that they were out of reach of hearing.

Several volleys of smoke, ascending from amidst the black mass of horses, prolonged the uncertainty. Some cried out, that it was our men firing, and still defending themselves, and that they were not yet beat. In fact, a Russian commanding officer had just been killed by the officer commanding these tirailleurs. This was the way in which he replied to the summons to surrender. Our anxiety lasted some minutes longer, when all at once the army set up a cry of joy and admiration at seeing the Russian cavalry, intimidated at this bold resistance, separate in order to escape their well-directed fire, disperse, and at last allow us to see once more this handful of brave fellows master of this extensive field of battle, of which it only occupied a few feet.

When the Russians saw that we were manœuvring seriously to attack them, they disappeared without leaving us any traces to follow them. This was the same they had done at Witepsk and Smolensk, and what was still more remarkable, the second day after their great disaster. At first there was some uncertainty whether to follow the road to Moscow or that to Kalouga, after which Murat and Mortier proceeded, at all hazards, towards Moscow.

They marched for two days, with no other food than horse-flesh and bruised wheat, without finding a single person or thing by which to discover the Russian army. That army, although its infantry only formed one confused mass, did not leave behind it a single fragment; such was the national spirit and habit of obedience in it, collectively and singly, and so thoroughly unprovided were we with every kind of information, as well as resources, in this deserted and thoroughly hostile country.

The army of Italy was advancing at some leagues' distance on the left of the great road, and surprised some of the armed peasantry, who were not accustomed to fighting; but their master, with a dagger in his hand, rushed upon our soldiers like a madman: he exclaimed that he had no longer a religion, empire, or country to defend, and that life was odious to him; they were willing, however, to leave him that, but as he attempted to kill the soldiers who surrounded him, pity yielded to anger, and his wish was gratified.

Near Krymskoié, on the 11th of September, the hostile army again made its appearance, firmly established in a strong position. It had returned to its plan of looking more to the ground, in its retreat, than to the enemy. The duke of Treviso at first satisfied Murat of the impossibility of attacking it; but the smell of powder soon intoxicated that monarch. He committed himself, and obliged Dufour, Mortier, and their infantry, to advance to his support. This consisted of the remains of Friand's division, and the young guard. There were lost, without the least utility, 2000 men of that reserve which had been so unseasonably spared on the day of battle; and Mortier was so enraged, that he wrote to the emperor, that he would no longer obey Murat's orders. For it was by letter that the generals of the vanguard communicated with Napoleon. He had remained for three days at Mojaisk, confined to his apartment, still consumed by a burning fever, overwhelmed with business, and worn out with anxiety. A violent cold had deprived him of the use of his voice. Compelled to dictate to seven persons at once, and unable to make himself heard, he wrote on different papers the heads of his despatches. When any difficulty arose, he explained himself by signs.
