Russia Against Napoleon

If Blücher’s army was to invade central Saxony it had to cross the Elbe. All the fortified crossings were in Napoleon’s hands, which meant that only he could move his troops across the river rapidly and in full security. The only way for Blücher to cross was by building pontoon bridges. For this he depended on his Russian pontoon companies, who did an outstanding job in getting the Army of Silesia across first the Elbe and later the Rhine. Their bridges were distinctly ramshackle affairs. A senior Russian staff officer in Blücher’s army recalled that ‘these bridges, which only lay a couple of feet above the surface of the water, had to be crossed with great care. They moved up and down all the time, horses had to be led, and any damage to the tarpaulin of one of the barges could immediately sink it.’ Once the army had crossed the river, either it dismantled the bridge and abandoned its communications or it had to construct field fortifications to protect the bridgeheads. The latter could never be as strong as permanent fortresses and therefore required much bigger garrisons. An army crossed such bridges much more slowly than over a permanent structure. It therefore had a higher chance of being caught by the enemy while moving across a river. The nightmare for any commander was to be forced to cross such a bridge in a hurry with Napoleon on his tail. True disaster loomed if the weather then turned against them, damaged the pontoons or made the bridge impossible to cross.²³

Inevitably, to see things just from the allied perspective is to forget that Napoleon too faced serious problems. By standing on the defensive in Saxony with a large army he doomed his men, and above all his horses, to hunger. The marches and counter-marches imposed by the allied Trachenberg strategy exhausted Napoleon’s young conscripts. The hostility of the local population and, above all, his great inferiority in light cavalry made it difficult to gather intelligence. His main base at Dresden, on which his army’s supply of food, ammunition and fodder greatly depended, was inadequately fortified and only one day’s march from the Austrian border. Odeleben, still in Napoleon’s headquarters, relates these and other problems and recalls that Napoleon’s great aim and hope in the autumn campaign was to pounce on allied mistakes. This hope was realistic given the theatre of operations, the problems of coalition warfare, and the failings of the allied commanders.²⁴

Telling the story of the first weeks of the autumn 1813 campaign in Germany is complicated by the fact that fighting occurred on three distinct fronts. The main army under Schwarzenberg in the south, Blücher’s Army of Silesia in the east and Bernadotte’s Army of the North in front of Berlin operated independently and it is necessary to follow each of their campaigns in turn for the sake of clarity. Only after the first half of the autumn campaign was concluded and the three allied armies advanced into Saxony towards Leipzig is it possible to tell the story of the campaign as a single integrated narrative.

Predictably, of the three allied army commanders it was Blücher who was off to the quickest start after the expiry of the armistice. In fact, thundering that ‘it’s time to finish with diplomatic buffoonery’, he went into action even before hostilities were supposed to start.²⁵ Egged on by Barclay, he seized as an excuse minor French infractions of the armistice terms and invaded the neutral zone between the opposing armies in Silesia on 13 August. This move made sense. In a province exhausted by the presence of two big armies in June and July 1813 the neutral zone around Breslau stood out because its harvest had barely yet been tapped. This was a prize worth cornering for oneself and denying to the enemy.

More important, Blücher’s move seized the initiative and forced Napoleon to respond to allied movements rather than himself dictating events. The advance of the Army of Silesia, for example, diverted Napoleon’s attention from Barclay’s columns of Russian and Prussian troops, which at this time were marching south-westwards to join Schwarzenberg’s army in Bohemia. Had the French attacked these columns while they were strung out on the march the consequences could have been serious. In addition, by seizing the initiative Blücher caught the French forces opposite him by surprise and pushed them right back out of the neutral zone and all the way over the river Bober. Blücher advanced with Sacken’s Army Corps of 18,000 Russian troops on his right, Yorck’s 38,000 Prussians in the centre and Langeron’s 40,000 Russians on his left.
