Russia Against Napoleon_ The True Story of the Campaigns of War and Peace - Dominic Lieven [306]
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.
There were problems with Blücher’s plan. Langeron’s and Bülow’s men would take no part in the battle and were therefore to some extent wasted. The terrain over which Winzengerode and Kleist were supposed to make their flank march was not properly reconnoitred and turned out to be very difficult. Rocks, hills, streams and broken ground caused great delays even to the cavalry, let alone the guns. A better general than Winzengerode might well have overcome these difficulties
