Russia Against Napoleon

Thanks to his infantry’s discipline and steadiness Sacken succeeded in extricating his corps with most of its baggage and artillery and retreated during the evening and the night down the awful road which led northwards to the river Marne at Château Thierry. Fires were lit every two hundred paces to guide the infantry along the way. In the drenching rain, with their muskets useless, the Russian infantry had both to march in compact masses to keep the enemy cavalry at bay and on occasion to break ranks in order to pull their artillery out of the mud. Though very outnumbered, Ilarion Vasilchikov and his splendid cavalry regiments greatly helped to protect the infantry and to drag away most of the guns. Napoleon pressed the retreating Russians hard and by the time they finally got across the Marne they had lost 5,000 men. Russian casualties would have been far higher had it not been for the courageous rearguard actions of Yorck’s Prussian infantry. Sacken was a hardbitten old campaigner and ‘politician’. The day after the battle, finally tracked down by his nervous and exhausted staff, who had lost him in the course of the retreat, he was as calm and self-assured as always. In the best traditions of coalition warfare, in his official report he blamed the defeat on the Prussians, and in particular on Yorck’s failure to obey Blücher’s orders and support him in good time.⁵⁶ Having defeated Yorck and Sacken, Napoleon was preparing to march south to block Schwarzenberg when he learned to his astonishment on 13 February that Blücher was advancing down the road which led to Montmirail. Blücher had misinterpreted the retreat of the French forces watching the road and believed that Napoleon was already heading south against the main army. Instead, having reached Vauchamps by the morning of 14 February, Blücher found himself confronted by Napoleon himself and the bulk of his army, which greatly outnumbered the allied force. Like Sacken’s troops three days before, Blücher’s infantry was forced to retreat in square for many miles under heavy pressure. At least Sacken’s foot soldiers had Vasilchikov’s cavalry and Yorck’s Prussians to help them. Blücher’s 16,000 infantry on the contrary were retreating on their own, in broad daylight, through excellent cavalry country and with very few horsemen to help them. Unlike Sacken’s veterans, most of the 6,000 Russians in Lieutenant-General Kaptsevich’s corps were new recruits, in action for the first time. Their musketry was at times more enthusiastic than effective. One-third of the men became casualties but, as French observers recognized, it was a tribute to the great courage and discipline of the Russian and Prussian infantry that Blücher’s whole detachment was not destroyed.⁵⁷ In the course of five days’ fighting Blücher’s army had lost almost one-third of its men. Napoleon was ecstatic. Already on the evening of 11 February he was writing to his brother Joseph, ‘this army of Silesia was the allies’ best army’, which was true enough. Much less truthfully, he added: ‘The enemy army of Silesia no longer exists: I have totally routed it.’ Even a week later, when there had been time to weigh the true results of the battle, he claimed in a letter to Eugène de Beauharnais to have taken more than 30,000 prisoners, which meant that ‘I have destroyed the Army of Silesia’. The reality was very different. On 18 February, the day after Napoleon wrote this letter, 8,000 men of Langeron’s Army Corps arrived to reinforce Blücher and there were many more Russian and Prussian units of the Army of Silesia, now relieved from blockading fortresses, on the march. Hundreds of prisoners of war were recaptured and many missing men returned to the ranks in the days immediately after the battle. Within a matter of days, Blücher’s army was again as strong as it had been on 10 February.⁵⁸

Ironically, in the end it was Napoleon himself who suffered most from his victories against Blücher. After the battle of La Rothière Napoleon very grudgingly granted Caulaincourt full powers to accept the allied peace conditions. On 5 February the foreign minister was told that ‘His Majesty gives you carte blanche to bring the negotiations to a happy end, to save the capital and to avoid a battle on which the last hopes of the nation would rest’. Caulaincourt was bewildered by these instructions and asked for clarification, enquiring whether he was supposed to concede all the allied demands immediately or whether he still had some time for negotiation. Before there was time to reply, Napoleon had defeated Blücher and his tone had changed completely.⁵⁹
