Continuing The March Since Minard’s map is in French, I have provided an English language version for us to use as we discuss the flow of Napoleon’s march in detail. 
The night of 13/14 September, Rostopchin also evacuated the 2000-odd members of the fire brigade and nearly one hundred water pumps from the city. What followed remains uncertain. There is evidence to suggest that Rostopchin gave the order to set fire to the city once the army had left. It may have also been part of the general scorched earth policy of the Russian army ever since the Grande Armée had crossed the border. It equally could have been brought about from looting on both sides. All that is known is that no orders for such an act were given by Napoleon or Alexander (irrespective – in the case of the former – of later Russian propaganda). Whatever the case, early on 15 September Napoleon entered an almost completely deserted Moscow. The population, about 262,000 in 1812, had left, with only 10,000 (some of whom were wounded soldiers) remaining. By midday he had set up his headquarters in the Kremlin. The nature of the evacuation had left a large quantity of food and drink in the city. Yet by the end of the day, the first fires had broken out within the city walls. Between 10.30pm and midnight, the fire spread further, leaping quickly between the closely packed buildings and warehouses. As the wind picked up, controlling the fire became more and more difficult. By the morning of 16 September, the fire had intensified. The Arbat – the historical centre of the city – was destroyed and the University of Moscow’s library had gone up in flames. At midday that day, Napoleon was encouraged to evacuate the Kremlin. Refusing, he remained in the palace until 5.30pm when, “besieged by an ocean of flames” (in Ségur’s words), he was obliged to flee. He and his officers set up camp in the Petrovski Palace, a few kilometres north-west of Moscow, on the St Petersburg road. The remaining French troops, being completely without the means to bring the fire under control, left the city at the same time. Eugene de Beauharnais lead his troops out on the road to Zvenigorod (to the west). Ney headed north-west towards St Petersburg. Davout took the road to Smolensk. The French forces remained outside of the city limits until 20 September when, as the rain came to fall, the fire was extinguished. Returning to the city that day, the army – officer and common soldier alike – descended into a frenzy of pillage.
In the absence of police or any sort of authority, many Russians still in the city joined in. Napoleon returned to the Kremlin. A third of Moscow’s houses were utterly destroyed, whilst only 122 out of 329 churches remained standing after the fire and destruction. Meanwhile, Kutuzov and the army had evacuated the city on 13/14 September. Initially heading out towards Ryazin’, they had passed through Lyubertsy on 16 September and continued south-east. Then, Kutuzov suddenly turned west and passed back in front of Moscow at high-speed. Fortunately for the Russians, the Grande Armée was to prove too exhausted to follow the withdrawal. On 18 September Kutuzov was in Podolsk, before continuing on to his encampment near Tarutino, about 100km to the south-west of Moscow. This position not only allowed him to harass the French lines of communication, but also stay in contact with the Russian forces under Tormasov and Chichagov, commander of the Army of the Danube. He was also well placed to watch over the workshops and arms factories in nearby Tula and Briansk, and receive supplies which came up to Kaluga from the fertile lands to the south, in modern-day Ukraine. Napoleon was left with a few choices. He could make his winter quarters in the ravaged city of Moscow. He could head south towards the breadbasket of The Ukraine. Or he could make for St Petersburg. This latter option would have been feasible had he the men and the material, but as it was, he would be forced to march through the winter-ravaged land with the possibility of being cut off by the remaining troops under Kutuzov. Napoleon however seemed convinced that an approach to treat from Alexander was imminent. Nor was a great deal of coordinated effort made to organise winter equipment and supplies. Napoleon, by various means, sought to engage Alexander, but each one remained ignored. On 20 September, Napoleon wrote to Alexander: “The beautiful and fine city of Moscow is no more: Rostopchin has had it burnt down. Four hundred arsonists have been caught in the act; they all declared that they were lighting the fire on the order of this governor and the director of police: they have all been shot. The fire now seems to have abated. Three-quarters of the houses have been burnt, one-quarter remains. […] How is it possible to destroy one of the most beautiful cities in the world and the work of centuries in the achievement of such a weak aim? […] The fire has opened the way to pillage, in which the soldiery is competing with the fire for the remains. If I once for a moment imagined that such things had been done on Your Majesty’s order, I would not be writing this letter; however I am convinced that it is impossible, given your principles, your spirit and your enlightened ideas, that you ordered such excesses, unworthy as they would be of so great a sovereign and so great a nation. […] I made war against your majesty without bitterness; one word from you, whether before or after our recent battle, would have stopped my advance and I would even have agreed to forgo the advantage of entering Moscow.” [20 September, 1812, Correspondance générale, Fayard/Fondation Napoléon, 2012, n° 31,736, p. 1,103] Upon learning of Kutuzov’s movements, he dispatched Bessières to observe the Russian movements. Poniatowski and his force reached Podolsk on 24 September. By 4 October, Napoleon knew that a decision had to be taken. Macdonald’s siege of Riga was threatened by the arrival of Governor of Finland Faddey Steingell at the head of 10,000 men. Although Macdonald successfully repelled the threat, Steingell linked up with Wittgenstein, still in the area. To the south-west, Chichagov and Tormasov threatened Schwarzenberg, based near Brest-Litovsk. There were over nine hundred kilometres between Riga and Moscow, and more than a thousand kilometres between Napoleon and Brest-Litovsk. Any further advance would simply increase these distances. In the end, Napoleon was to stay in the Moscow about a month. What was the plan there? The mounting of an attack on St Petersburg was apparently mooted; huge amounts of stores were amassed with the idea of wintering in the Russian capital; reinforcements were on their way from Smolensk. But the situation in Moscow was not good. The city was half burnt and the troops had plundered much. And not far to the south-east, the Russian army, by no means out of action, was preparing to counterattack. Furthermore, partisan units were successfully harrying transport columns, and, as the encounter at Taroutino would show, despite their chaotic approach, the Russians were still a force to be reckoned with. Kutuzov was later to boast that he had played the French emperor, dragging out negotiations with Napoleon because the Russian knew that the French in Moscow were stuck in a trap. It is possible however that, taking into account the fact that he said this in December 1812, this assertion was made with the benefit of hindsight. And in the same conversation, Kutusov also convincingly remarks that he thought that Napoleon had waited too long, letting himself be obsessed with obtaining a peace treaty instead of continuing to be belligerent. Be that as it may, Napoleon’s actions in Moscow seem to imply hesitation, and in the mental and strategic void, the emperor took the fateful step of heading, too late, back west.
