Perhaps the most extraordinary point amidst all this chaos is that the Russians did actually win the battle of Tarutino. Murat was driven off the battlefield with a loss of 3,000 men and many cannon, standards and other booty. This was small consolation for most of the Russian generals, and above all for Bennigsen and Toll who had masterminded the operation. Given Murat’s carelessness and Russian numbers, the surprise attack should have destroyed much of his detachment. Bennigsen saw Kutuzov’s refusal to commit Miloradovich’s troops as deliberate sabotage born of the field-marshal’s envy of any rival who might steal his glory. Though the battle of Tarutino spread the poison at headquarters, its impact on the junior officers and men was the exact opposite. They rejoiced in the fact that for the first time in 1812 the main army had attacked and defeated the enemy. Kutuzov made sure that all the trophies captured on 18 October were laid out for his men to see. He organized a Te Deum to celebrate the victory, which he reported in glowing terms to Alexander. Whatever his limitations as a tactician, Kutuzov was a master when it came to public relations and his troops’ morale.24
Napoleon heard the news of Murat’s defeat while inspecting troops near the Kremlin. The emperor was always acutely sensitive to anything that reflected on his own prestige and his army’s victorious reputation. Now not merely would he be retreating from Moscow but would be doing so after a defeat. On the next day, 19 October, he left the city with his army’s main body, leaving a substantial rearguard behind to complete the evacuation and blow up the Kremlin. During the month of October he had contemplated a number of possible moves after leaving Moscow. The most conservative would be to retreat the way he had come, down the highway to Smolensk. This was the quickest way to get back to his supply bases at Smolensk, Minsk and Vilna and took him down Russia’s best road, which was a major consideration given the vast and motley baggage train he was dragging along in his wake. But the area along the road had been devastated and his army would find little food or quarters.25
The obvious alternative was to move on Kaluga, Kutuzov’s main supply base one week’s march to the south-west of Moscow. Napoleon even contemplated then turning towards the great armaments centre at Tula, at least an additional three days’ march to the south-east. Capturing Tula would badly damage the whole Russian war effort. Taking Kaluga might net some supplies for Napoleon and would disrupt any subsequent Russian pursuit of his army. It would also conveniently hide the fact that the French were retreating. From Kaluga, Napoleon could withdraw down the relatively good road which led through Iukhnov to Smolensk and Belorussia.
With November and winter only two weeks away Napoleon could not afford detours and delays. There were strict limits to how much food he could carry with him from Moscow. As always, the biggest problem was the enormously bulky fodder for the horses. Every day of extra marching brought hunger, winter and disintegration that much closer. To be sure, he could feed and quarter his army more easily along the Kaluga–Smolensk road than on the Moscow–Smolensk highway but the advantages of this should not be exaggerated. To survive, his army would need to forage well away from the road and the overwhelmingly superior Russian light cavalry would make this impossible. The French army was never likely to match the steady discipline of Russian rearguards. In addition, by late October 1812 the state of Napoleon’s horses meant that his rearguards would lack two crucial components: sufficient cavalry and fast-moving artillery. While facing Russian light cavalry and horse artillery in overwhelming numbers, there was no chance of the French maintaining a steady, methodical retreat. Speed was the only option and rapid retreats turned easily into rout.
The basic point was that by mid-October Napoleon had no safe options. Unless he was very lucky or the Russians blundered terribly his army was going to suffer great losses during its retreat. The key to minimizing these losses would be discipline. If the men abandoned their units and disobeyed their officers, disaster would be inevitable. Every scrap of food in Moscow had to be collected and a system of fair distribution established down the hierarchy of command. Not merely would this ensure that everyone got their share, it was also a vital method of maintaining control and discipline. Superfluous baggage, civilians and plunder had to be reduced to a minimum. Elementary precautions – such as shoeing the horses against winter ice – needed to be taken in time.
