Russia Against Napoleon

In the end a compromise was hammered out in a conference of the allied leaders at Bar-sur-Aube on 25 February. Schwarzenberg would continue his retreat as far as Langres if necessary, where he would be joined by the newly arriving Austrian reserves. If Napoleon was still pursuing him he would turn at Langres and fight a defensive battle. Meanwhile Blücher was to march northwards and, it was hoped, draw Napoleon off Schwarzenberg’s back by threatening Paris. If, as was expected, Napoleon turned round and pursued Blücher, Schwarzenberg was to resume the offensive. Bülow and Winzengerode’s Army Corps of Bernadotte’s former Army of the North had in the meantime marched from the frontiers of Holland towards Paris and were now approaching Soissons on the river Aisne. They would come under Blücher’s command, as would the newly formed Saxon corps of the German federal forces, whose job it would be to hold the Low Countries. Even without the Saxons, Blücher’s combined army would total over 100,000 men, which by now was considerably more than Napoleon’s entire force. Alexander’s instructions to the Prussian field-marshal reflected both his awareness that only Blücher had the confident aggression necessary for victory and his great fear that a repetition of Blücher’s earlier carelessness might wreck the allied cause. They concluded with the words, ‘as soon as you have coordinated the movements of your various corps we wish you to commence your offensive, which promises the happiest results so long as it is based on prudence’.⁸ Blücher set off northwards immediately. Unlike during his earlier offensive towards Paris, on this occasion the Russian cavalry was deployed to guard all the roads from the south. By 2 March it was clear from their reports that Napoleon was pursuing the Army of Silesia with a large force. The first objective of Blücher’s manoeuvre had thus been achieved. The next task was to unite with Winzengerode and Bülow, who were currently surrounding Soissons, which was important because its bridge offered a secure passage over the river Aisne. Vladimir Löwenstern was sent into the town as an emissary by the allied commanders. He used all his gambler’s tricks of bluff, aggression and charm to persuade the French commandant to surrender Soissons on 2 March.

Napoleon was furious, ordered the commandant to be shot, and claimed that if the city had not surrendered he would have pinned Blücher with his back to the Aisne and destroyed his army. Most Prussian historians angrily deny this and claim that the Army of Silesia could have crossed the Aisne elsewhere. On the other hand, some of General von Bülow’s supporters were only too happy to argue that their hero had rescued Blücher from a tight spot. Inevitably they neglected to mention that the chief agent of this rescue was not a Prussian but Löwenstern. To an even greater extent than normal in 1813–14, the Russian role is neglected and what actually happened is obscured amidst a cacophony of French and German nationalism and machismo. Probably the Prussian historians are right and Blücher would have escaped Napoleon’s clutches, but some at least of the allied force would have needed to cross the river over the Army of Silesia’s Russian pontoon bridges, never an easy task with Napoleon in the offing and made no easier by the Aisne’s flooding banks.⁹

The French army crossed the river Aisne at Berry-au-Bac to the east of Soissons on 5 March. Napoleon intended to advance on Laon; he was under the illusion that the allies were retreating and that all he would meet would be more or less determined rearguards. Blücher decided to pounce on the French as they advanced towards Corbeny and Laon. He deployed Winzengerode’s 16,300 infantry under the command of Mikhail Vorontsov on a plateau just to the west of the Laon road near the village of Craonne. Correctly, he believed that the emperor could never push on to Laon with this force on his flank and would need to concentrate first on defeating Vorontsov. Fabian von der Osten-Sacken’s Army Corps was deployed some kilometres behind Vorontsov on the plateau to support him in case of need. While Vorontsov’s Russians were pinning down Napoleon and occupying his attention, Blücher intended to march 10,000 cavalry under Winzengerode and the whole of Lieutenant-General von Kleist’s Prussian Army Corps around the French northern flank and into their rear. Meanwhile Bülow would shield Laon and Blücher’s communications with the Low Countries, while part of Alexandre de Langeron’s force would remain behind to hold Soissons.
