Russia Against Napoleon_ The True Story of the Campaigns of War and Peace - Dominic Lieven [265]
At Leutmeritz Bennigsen received Alexander’s orders for the coming campaign. His chief task was to defend the main army’s bases and communications in Bohemia. If Napoleon invaded the province then Bennigsen was to fall back on the strong defensive position behind the river Eger. If on the contrary the French moved against the main army then Bennigsen was to advance up the Teplitz highway into their rear. On 30 September General Dokhturov’s men arrived in the Teplitz valley and began to occupy the former bivouacs of the Army of Bohemia. The Leipzig campaign was about to begin.9
Schwarzenberg’s advance guard began to move northwards on 27 September. On this occasion the Army of Bohemia would be using just one of the two highways through the Erzgebirge, in other words the road from Kommotau through Chemnitz to Leipzig. Inevitably this slowed down its movements. Both Schwarzenberg and Barclay were acutely conscious of the army’s vulnerability to a sudden attack by Napoleon as it emerged from the mountains. With so much of the light cavalry away in raiding parties around Leipzig, reconnaissance was a problem. Wittgenstein and Kleinau commanded the leading allied corps: the former had no Cossacks and the latter only 1,200 light cavalry. Despite Barclay’s worries about supplies, the area between Chemnitz and Altenburg had never been fought over and food and fodder turned out to be relatively abundant. Schwarzenberg advanced out of the Erzgebirge with 160,000 men. Facing him were only 40,000 men under Joachim Murat. But the allied movements were so slow and uncoordinated that Murat was easily able to delay them and even score a number of minor victories in skirmishes. The pressure on his force was so weak that Murat believed that he was facing only part of the Army of Bohemia, with Schwarzenberg and the main body probably still poised to move on Dresden. Murat’s reports to this effect misled Napoleon but the key result of Schwarzenberg’s caution was that Napoleon was free to turn on Blücher and Bernadotte with the great majority of his army.10 Blücher’s army began its march northwards to link up with Bernadotte on 29 September. On 3 October his Russian pontoon companies got Blücher’s Prussians across the Elbe at Wartenburg. Though outnumbered, the French forces at Wartenburg held very strong positions, which Yorck’s infantry stormed with great courage. Meanwhile Bernadotte kept his promise to cross the Elbe to join the Army of Silesia: all three of his corps crossed the river on 4 October at Rosslau and Aken. Winzengerode had orders from Bernadotte to attack Ney’s rear if the French advanced against Blücher. The Army of Silesia headed south-eastwards towards Düben with Yorck in the lead, followed by Langeron, with Sacken’s corps bringing up the rear. Having abandoned their bases east of the Elbe Langeron’s men were already having to scrounge food from the local countryside and some of them were beginning to go hungry. Captain Radozhitsky complained that marching in the wake of the Prussians was always unpleasant because they stripped the country bare, treating the Saxon population much worse than the Russians’ behaviour towards the Poles when marching through the Duchy of Warsaw earlier in the year.11
For their own safety and if the campaign was to succeed the armies of Silesia and of the North had
