One reason why Schwarzenberg liked the plan was that he had never initially intended to bring on a great battle at Leipzig. His aim throughout the October campaign had been to block Napoleon’s retreat to the west and force the emperor to attack the allied forces standing in his path. Though not totally implausible as a strategic concept, his efforts to translate this idea into tactical deployments around Leipzig were a disaster. There was in any case a very basic problem with the Austrian plan. Napoleon had not concentrated his forces in Leipzig in order to retreat westwards. He was intending to smash the Army of Bohemia and win the campaign.
Napoleon took it for granted that the bulk of the enemy army would be deployed in the only sensible place, in other words east of the rivers Elster and Pleisse. His plan was to turn the allies’ right flank east of Liebertwollkwitz, smash through their centre and drive Schwarzenberg’s army into the Pleisse. Even without Bernadotte and Bennigsen the allies had 205,000 troops available on 16 October against Napoleon’s 190,000. But Schwarzenberg’s plan, even after modifications to appease Alexander, meant that on the key southern front 138,000 French troops would face 100,000 allies, of which Constantine’s 24,000 reserves could not arrive on the battlefield for a number of hours. Of course the allies would outnumber Napoleon in other sectors but the terrain would make it impossible to use this superiority. On the first day at Leipzig Schwarzenberg therefore gave Napoleon a completely unnecessary chance to snatch victory against the odds and against the previous flow of the autumn campaign.22
On 16 October Blücher’s army advanced on Leipzig from the north. Langeron took the village of Euteritzsch and Yorck’s corps finally stormed Möckern after a ferocious struggle which lasted until the evening. The main point, however, was that Blücher had succeeded in pinning down two large French corps in the north, including Marmont’s men, on whom Napoleon was depending for his attack on Schwarzenberg. Blücher’s achievement at Leipzig was similar to his impact on the battle of Waterloo. By arriving on the battlefield much earlier than Napoleon had predicted, he diverted a key part of the strategic reserve on which the emperor was counting to decide the battle on its main front.
West of Leipzig, the advance on Lindenau of Gyulai’s Austrian troops forced Napoleon to send the whole of Bertrand’s Fourth Corps across the rivers to secure the village, and with it his line of retreat to the west. Further south, all the Austrian attempts to cross the river Pleisse near Connewitz and Dölitz got nowhere, to Schwarzenberg’s increasing frustration. By late morning he was prepared to give way to Alexander’s pleas and agree that Langenau’s plan had failed. He therefore ordered the Austrian reserves to cross the Pleisse to help beat off Napoleon’s attack. By now the allied situation east of the Pleisse was increasingly dire. The key question was whether the Austrian reserves would arrive in time to shore up the allied line.
Eugen of Württemberg’s Second Russian Corps was deployed near the centre of the allied line east of the Pleisse, in front of the village of Gossa. In his memoirs Eugen wrote that from Gossa on 15 October Napoleon could be seen on the heights near Wachau inspecting his troops and handing out medals. Eugen and his officers expected themselves to be attacked the next day but ‘we could not understand why Schwarzenberg decided on a general attack for the 16th when on the following day we would have been strengthened by 130,000 men of the Army of the North, the Army of Poland, and Count Colloredo’s corps’. It seems that the allied high command wished to pin down Napoleon and feared that he would otherwise attack Blücher and Bernadotte, and perhaps even slip away to the north.23
To avoid this, the allied forces east of the Pleisse were ordered to attack in four columns from early in the morning of 16 October. On the left Kleist’s Prussian corps and Helfreich’s 14th Russian division would advance on Markkleeberg. To Kleist’s right Eugen’s Second Corps would attack Wachau, supported by Klux’s Prussian brigade. The third column was commanded by Lieutenant-General Prince Andrei Gorchakov. It comprised Gorchakov’s First Corps and Pirch’s Prussian brigade. Gorchakov would attack Liebertwollkwitz from the south-west while the fourth column, made up of General Klenau’s Austrians, would advance on the village from the south-east.
