Russia Against Napoleon_ The True Story of the Campaigns of War and Peace - Dominic Lieven [263]
The victory of Dennewitz and the arrival of reinforcements for the Army of Bohemia changed some of Jomini’s numbers without altering the basic strategic issue. Not at all surprisingly, Blücher was deeply unwilling to lose his independence and become a mere adjunct of Schwarzenberg’s lumbering army. He wrote to Knesebeck as follows: for the ‘sake of the common good, preserve me from a union with the main army; what can such a vast mass of men achieve in terrain of that sort?’ Another letter from Blücher, drafted by Gneisenau and dated 11 September, went directly to Alexander and stressed the impact on Bernadotte if Blücher moved away from him and towards Bohemia: ‘The battle of 6 September [i.e. Dennewitz] has certainly changed the military position within the theatre but the crown prince of Sweden would probably straight away and with good reason fall into inactivity if he noticed that the Army of Silesia was moving a long way away from him.’3
Caution was required when writing on such delicate themes. Along with the letter, Blücher also sent his excellent staff officer, Major Rühle von Lilienberg, to pass on his views orally to Alexander and Frederick William. Rühle stressed Blücher and Gneisenau’s opinion that ‘so long as the crown prince is deployed on his own in a separate theatre of war we can expect no activity from him because of his political position’. The combination of written and oral urgings convinced the monarchs and had a decisive influence on the future of the campaign. Blücher was allowed to remain independent and to plan his crossing of the Elbe and link-up with Bernadotte. Nesselrode wrote to Pozzo to keep the crown prince in line during the forthcoming military operation. Meanwhile Bennigsen’s Army of Poland would be diverted from its march across Silesia and would instead be brought southwards to Bohemia to guard Schwarzenberg’s right and rear.4
On 13 September Alexander wrote to Blücher to tell him that General von dem Knesebeck was coming to him with instructions which would give Blücher wide leeway to plan his forthcoming operations. On the same day he wrote to Bennigsen ordering him to march to Bohemia. The emperor simply told Bennigsen, ‘I think that it would be difficult to turn him [Blücher] from the direction he has taken’, and gave the commander of the Army of Poland the march-routes he was to follow into Bohemia. He stressed the urgency of the movement and that Bennigsen was to report daily. Bennigsen received Alexander’s orders at Hainau on 17 September. He immediately stirred up his corps commanders, allowing Count Tolstoy’s militia just one day’s rest at Liegnitz and telling their general to leave behind any units incapable of combat in the field. It would take Bennigsen’s men at least two weeks, however, to reach Bohemia along bad roads, in areas already eaten out by passing troops and in dreadful weather. Bennigsen subsequently reported daily to Alexander on all these problems but he did add that the Austrian commissariat on this occasion had done a good job in keeping his army fed.5
While Bennigsen’s men were on the march most of the allied troops were resting. Military operations were largely confined to the light troops which by now were swarming in Napoleon’s rear and doing great damage to his supplies. Both east and west of Leipzig, Russian, Prussian and Austrian light cavalry and Cossacks forced Napoleon to divert ever larger escorts to supply trains. Even this did not guarantee safety. On 11 September a supply convoy west of Leipzig with an escort of 4,000 infantry and 1,500 cavalry was overwhelmed by an allied force. Alexander ordered Blücher to release six Cossack regiments which he wanted to redeploy behind enemy lines in western
