Sacken’s report on the battle concluded with a courtier’s flourish: ‘On this memorable and triumphant day Napoleon ceased to be the enemy of mankind and Alexander can say, I will grant peace to the world.’ Language like this was dangerously premature. Napoleon was not dead yet and the Army of Silesia was to be punished for its overconfidence in just a few days’ time. For Sacken himself, however, the battle had been a triumph. For his victories in 1813 he had been promoted to full general and awarded a string of decorations. Now Alexander granted him the very coveted Order of St Andrew and made him a present of 50,000 rubles. Probably most important for Sacken, however, was the emperor’s remark to him on the day after the battle: ‘You have conquered not only your foreign but also your domestic enemies.’ The old battle with Bennigsen dating back to 1807 which had embittered Sacken and threatened his career was now decided in his favour. His great enemy would end his life as a general and a count. Sacken would race past him, both a field-marshal and a prince.42
The day after the battle the allied leaders held a conference in the chateau of Brienne to decide future strategy. When the time to begin the meeting arrived, apparently Blücher was nowhere to be found and the various dignitaries scattered to track him down. It was Alexander who discovered him, deep in the wine cellars, plucking the best bottles from the racks. The conference decided that the main army and the Army of Silesia must split up, allegedly because it was impossible to feed them if they remained together. Schwarzenberg would advance on Paris from the south along the river Seine. Blücher would approach from the west along the Marne.43
In many ways this was to revert to the model of 1813 and to face the same dangers. Napoleon would be operating on interior lines between the two allied armies. By now he would be well attuned to Schwarzenberg’s caution and slowness, and to Blücher’s boldness and willingness to run risks. In the autumn of 1813 Napoleon had missed his chance to exploit this weakness. Now it had returned in even more clear-cut form. Unlike in the autumn, Napoleon would not have to exhaust himself by marching great distances to strike one or other allied army. Since all military operations were taking place in a small area, he could hope to defeat one enemy army and race back to face the other in a handful of days. Moving in his own country, he could mobilize local knowledge, transport and manpower to use side roads, tap food supplies and be forewarned about enemy actions. He also controlled most of the key river crossings. In addition, in February 1814 Blücher was even more inclined to take risks than before since he shared the widespread view that Napoleon’s demise was imminent. By 7 February he and Alexander were discussing how to quarter the troops when they reached Paris.44Meanwhile Schwarzenberg was even more cautious than in the previous year. The great numerical superiority of the allies seems to have merely increased his worries about the difficulties of commanding and feeding so vast an army. He was intensely concerned about the security of his long line of communications stretching back to Basle and across the Rhine. He exaggerated the size of Napoleon’s army and, still more, of the force which Marshal Augereau was trying to form in Lyons, believing that Augereau might strike into the allied rear in Switzerland. In these circumstances Schwarzenberg was very opposed to any further move forwards. As he wrote to his wife on 26 January, ‘any advance on Paris is in the highest degree contrary to military science’.45
To do the commander-in-chief justice he was not alone among the allied generals in this view. Knesebeck argued that it would be very difficult to feed the army in the region around Troyes through which they would have to approach Paris. The various allied corps could only move up and down the north–south highways leading to the capital since the side roads were almost impassable at this time of year. Lateral movements and mutual support among the allied corps would therefore be slow at best. Meanwhile Napoleon could feed himself from the fertile areas west of Paris and could use interior lines and better lateral roads which he controlled to concentrate and strike against the lumbering allied columns. If Napoleon’s throne was threatened, no doubt he would fight to the death. What evidence was there that the French nation would desert him? Ultimately, to advance on Paris was to gamble on French politics. Might this not prove as deceptive as Napoleon’s gamble in 1812 that occupying Moscow would lead to peace?46
