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.
Count Alexandre de Langeron, the senior Russian officer in Blücher’s army, was one of the many French émigrés in Russian service. His first experience of battle had been in the American War of Independence. He had joined the Russian army besieging the Ottoman fortress of Izmail in 1790, partly out of a sense of adventure but also, so it was whispered, to escape the consequences of a duel with a bishop. Langeron won the respect of the Russians by the courage and enterprise he showed during the siege and he remained in Russian service for the rest of his life. The first time Langeron saw Paris in many years was when his troops stormed the heights of Montmartre outside the city’s gates in March 1814. He worked his way up the army’s ranks, fighting mostly against the Turks but also at Austerlitz, where his less than brilliant performance excited Alexander’s anger and almost cost him his career. Subsequently Langeron had regained favour through his performance against the Turks, but few people doubted that the count was a competent rather than a brilliant general.26
Langeron cut something of a strange figure in Blücher’s Russo-Prussian army. He was very much the southern Frenchman, dark in complexion with black eyes and hair. He had the charm, the wit and the conversation of the Old Regime Parisian salons. He wrote tragedies and songs. Extremely absent-minded, he loved word-games, puzzles and charades. At times he would march up and down, his head down, his hands behind his back, lost in his thoughts and riddles. On the battlefield, however, he was calm and imposing and had a good eye for terrain. He had learned to speak a fluent and voluble Russian but in a weird accent that was often incomprehensible to his soldiers. Nevertheless he was well liked by the men and the admiration was mutual. One of his most endearing characteristics was his enormous admiration for the courage, decency and self-sacrifice of the ordinary Russian soldiers whom – as he always put it – he had the great honour to command. Perhaps there was in this a touch of the colonial officer, who far preferred the doughty native peasantry to the vulgar and pushy bourgeois back at home. But Langeron was also generous, even chivalrous, to his officers, quick to give praise to others and often critical about himself.
As the senior Russian officer in Blücher’s army, however, Langeron had some responsibility for good relations between the Russian and Prussian troops and their commanders. This presented problems. Langeron spoke no German and Blücher had not a word of French or Russian. Communications went through Blücher’s chief of staff, Gneisenau, in the French language. Like most Frenchmen of his day, Langeron thought Germans were rather a joke, once commenting that ‘the heaviness, the stiff formality, the slow imagination of this nation and their uncouthness do not make them agreeable to other people’. Gneisenau hated the French even more than Langeron disliked the Germans. In addition, Blücher’s chief of staff was something of a radical, who dreamed of arousing the German people to the same level of nationalist frenzy which had seized France in the Revolution. A Frenchman with similar inclinations he would have hated but understood; an émigré count fighting against his own nation was a different matter.27
The command structure of the Army of Silesia in fact had the potential for disaster. Sacken and Blücher could at least communicate in German.
In time they came to admire each other’s qualities. Their good relations were an unanticipated blessing, however, because Sacken was a sharp-tongued and short-tempered man with a poor reputation as a subordinate. Even so, in comparison with Yorck he was an angel. The Prussian corps commander thought Blücher was an idiot and the much younger Gneisenau a mere theoretician of war and a dangerous radical. The fact that he was subordinated to this pair was an obvious disgrace to merit and common sense. It was with these senior commanders that the Army of Silesia woke up on 21 August to the fact that it now faced Nap
oleon himself, his Guards and the core of his reserves, which had raced up to support the corps retreating before Blücher’s forces.
Blücher reacted in accordance with the Trachenberg plan. His corps retreated and refused to become engaged in a major battle. As one might by now expect, the Russians did this with cool professionalism. On the right wing, outside Bunzlau, Sacken waited calmly for the five hours that it took the corps of Ney, Marmont and Sebastiani to deploy against him. Then he left it to the disciplined skill of Lieven’s infantry and Ilarion Vasilchikov’s horsemen to mount a rearguard action that frustrated the enemy commanders and kept the French at a respectful distance. In the Belostok Regiment alone ten soldiers won military medals for their calmness, courage and skill in the rearguard action at Bunzlau on 21 August. The infantry was helped enormously by the fact that Vasilchikov was one of the ablest light cavalry commanders in Europe and his regiments were far superior in every way to the horsemen of General Sebastiani’s French Second Cavalry Corps, by whom they were opposed.28
On the other wing of Blücher’s army Langeron’s rearguard also performed well under heavy pressure. Its cavalry was ably commanded by General Georgii Emmanuel, the son of a Serbian colonist in southern Russia. The overall commander of the rearguard was Aleksandr Rudzevich, a Crimean Tatar who had been baptized into the Orthodox Church at the age of 12. In principle, Rudzevich, a trained staff officer, was Langeron’s chief of staff. In fact, however, Langeron used his quartermaster-general, Colonel Paul Neidhardt, in this role and employed Rudzevich as his troubleshooter wherever the going was toughest. He wrote in his memoirs that Rudzevich, unique in his combination of staff training and long combat experience in the Caucasus, was much the ablest general in his Army Corps. For once, Blücher and Gneisenau agreed wholeheartedly with Langeron’s opinion. Gneisenau wrote to the Prussian chancellor, Hardenberg, that on 21 August Rudzevich’s rearguard risked being cut off by very superior enemy forces. Many generals would have lost their balance and judgement in so dangerous a position but Rudzevich had reacted with intelligence, calm and courage, pushing the French back and getting his men across the river Bober under their noses.29
How the Prussian troops, and above all the Landwehr, would cope with mounting a rearguard action against Napoleon was more uncertain. In fact the Prussians fought with courage and discipline in the four-day retreat back from the river Bober to behind the river Katzbach, where Blücher’s advance had commenced only eight days before. The Army of Silesia’s marches and counter-marches exhausted the troops, however, and in particular the Prussian militia. The 6th Silesian Landwehr Regiment, for example, was 2,000 strong when Blücher’s advance began; eight days later it had melted down to just 700 men. Above all, this was due to the speed of the army’s advance and subsequent retreat. In addition, it took time for Blücher’s staff to get into their stride: the Army of Silesia had after all only come together on the very eve of the campaign. In the retreat from the Bober to the Katzbach columns sometimes crossed or got entangled in baggage trains. Night marches were a particular source of exhaustion to Yorck’s corps.
Given the personalities involved, it was inevitable that tempers would explode. After a furious argument with Blücher, Yorck sent in his resignation to Frederick William III, noting that ‘it may be that my limited abilities do not enable me to understand the brilliant conceptions by which General Blücher is guided’.30 Blücher’s worst problems were with Langeron. Though personalities played a part, a more basic issue was their main cause. When the Trachenberg plan was originally devised, of the three allied groupings the only one explicitly urged to caution was the Army of Silesia. This was because at that time it seemed that this army would be only 50,000 strong. By the beginning of the campaign its numbers had actually doubled but Blücher’s instructions from the monarchs still urged him to avoid major battles. Blücher promptly responded that, if these were his orders, then the allies needed to find an alternative commander more suited to caution. Barclay and Diebitsch replied, no doubt in the monarchs’ name, that of course no one could stop the commander of 100,000 men from seizing whatever opportunities presented themselves. On this assurance Blücher accepted the command.31
Langeron was informed of Blücher’s initial instructions but not of the manner in which they had been changed by Barclay and Diebitsch. It is possible that this was an oversight amidst the frantic last-minute preparations to move Barclay’s force into Bohemia. It is also possible that it was a deliberate ploy by Alexander to use Langeron to check Blücher. There is no doubt that the emperor remained very nervous about where Blücher’s aggressive nature would lead. After receiving the news of the Army of Silesia’s initial advance to the Bober, for instance, he wrote to Blücher that ‘your recent battles which have been so glorious must not lead you to involve yourself in a full-scale engagement’.32
Whether deliberate or accidental, the treatment of Langeron was deeply unfair to both him and Blücher. Langeron had some reason to believe that he was acting in accordance with Blücher’s instructions and Alexander’s own wishes. He also had excellent reason to fear that if Napoleon was allowed just a few more days to pursue Blücher, the latter would stand and fight, whatever the odds. The commander-in-chief might indeed have had no choice in the matter since there was a limit to how much more retreating the Landwehr regiments could take before they disintegrated. In fact Blücher himself wrote to Alexander that if need be he would stand and fight against Napoleon even if seriously outnumbered, providing he could find a strong defensive position where he could deploy his artillery to advantage. Inevitably, Blücher was furious about the many occasions during the first two weeks of the campaign when Langeron disobeyed his orders in the name of caution. By 25 August he and Gneisenau had lost all patience and were determined to get Alexander to remove the Russian general.33
Very fortunately for the Army of Silesia, the Trachenberg plan worked as intended. By 23 August it was clear to Napoleon that he could spare no more time chasing Blücher. Schwarzenberg’s army was invading Saxony and threatening the key supply base of Dresden. Turning back to confront this danger with the Guards and the corps of Marmont and Victor, Napoleon left Marshal MacDonald to cope with Blücher. Under his command would be Sebastiani’s Second Cavalry Corps and the Third, Fifth and Eleventh Infantry corps. Though Napoleon left Third Corps to MacDonald, he ordered its commander, Marshal Ney, to hand over command to General Souham and himself to take control of the army facing Bernadotte in front of Berlin.
Before departing for Dresden Napoleon ordered MacDonald to advance over the river Katzbach and drive Blücher back beyond Jauer.
After this his job was to keep the enemy pinned down in eastern Silesia, far away from the crucial theatre of operations in Saxony west of the Elbe. MacDonald ordered his men to advance over the Katzbach on 26 August. Meanwhile Blücher was immediately aware of the departure of Napoleon and much of the enemy army. He therefore ordered the Army of Silesia to resume offensive operations, beginning with an advance over the Katzbach, also planned for 26 August. The scene was set for the crucial battle which took place on that day. Neither commander expected the other to advance. The resulting confusion when the two advancing armies bumped into each other was increased because heavy rain greatly reduced visibility.
MacDonald’s army advanced on a wide front. Two of his divisions, under generals Ledru and Puthod, were deployed well to the south near Schönau and Hirschberg. Their job was to tackle the small Russian Eighth Corps commanded by Count Emmanuel de Saint-Priest, another royalist émigré and Petr Bagration’s former chief of staff, and threaten Jauer from the southwest. This move would outflank Blücher’s army and endanger its communications and its baggage, which was concentrated in and near Jauer. Meanwhile at the other end of MacDonald’s line the Third Corps, deployed near Liegnitz, was ordered to cross the Katzbach at that city and then push down the road from Liegnitz to Jauer behind the allied right flank. The remainder of MacDonald’s army, made up of his own Eleventh an
d Lauriston’s Fifth Corps was to advance directly over the Katzbach towards Jauer. Having detached Ledru and Puthod, these two corps only amounted to four infantry divisions but they would be supported by Sebastiani’s cavalry.
There were dangers in dispersing the French army so widely. MacDonald seems to have assumed that Blücher would be static or in retreat.
This was a very dangerous assumption when facing so aggressive an enemy. A senior Russian staff officer subsequently wrote that failure to reconnoitre the allied position was the key to the French defeat at the Katzbach. For this not just MacDonald but also the atrocious weather and the poor quality of the French cavalry was to blame.34
The terrain over which MacDonald was advancing and on which the battle was fought added to the dangers of poor reconnaissance. Roughly speaking, before the battle the two armies were divided by the river Katzbach, which flows south-westwards from Liegnitz. The French were on the north bank and the allies on the south. MacDonald’s troops crossed the river and the battle took place on the south bank between the Katzbach and Jauer. The battlefield was divided into two distinct halves by the river Wütender Neisse, which flows from Jauer and joins the Katzbach at something approaching a right angle.
