The inactivity of the Army of Silesia allowed Napoleon to escape, rest and then pounce on the 12,000-strong detachment led by Emmanuel de Saint-Priest, Bagration’s chief of staff back in 1812, which had taken Rheims on 12 March. Although Napoleon had suffered at least 6,000 casualties at Laon, reinforcements arrived from Paris, bringing his army back up to 40,000 men. This was more than sufficient to defeat Saint-Priest, particularly since Napoleon caught the allies by surprise. To some extent this was Saint-Priest’s fault for not taking proper precautions but it was hard to predict that Blücher’s army would stand still, lose all track of Napoleon and fail to provide any warning as to his movements. Part of Saint-Priest’s force was made up of Prussian Landwehr, who had dispersed in search of food and put up little resistance when the French attacked on 13 March. Saint-Priest’s Russian regiments from his own Eighth Corps were made of sterner stuff, however, and put up a stiff fight, despite the fact that their general himself was severely wounded and out of action from the beginning of the battle.
The core of Russian resistance was the Riazan Regiment, an old unit with a fine fighting record, founded by Peter the Great in 1703. In the current war the regiment had fought at Borodino, Bautzen and Leipzig, where 35 per cent of its officers were killed or wounded and thirty-two of its men won military medals. General Saint-Priest himself was popular with his troops, of whom he took good care, for instance using a captured French treasury to buy new clothes for his soldiers in the winter of 1813–14. He had a particularly strong relationship with the Riazan Regiment, which he called ‘the Guards of the Eighth Corps’. The regiment’s inspiring commander was Colonel Ivan Skobelev, the son of a state peasant, who had served twelve years in the ranks before receiving his commission. Amidst the chaos on 13 March the Riazan Regiment’s third battalion built a breastwork in front of the main gate of Rheims and beat off French efforts to break into the city. Meanwhile, initially 2 kilometres outside the city’s walls, the regiment’s first battalion formed a square against the French cavalry and fought their way back to where their comrades of the third battalion were holding out, carrying the wounded Saint-Priest in their midst. The two battalions of the Riazan Regiment then formed the core of the Russian rearguard, commanded by Skobelev, which held up the French for long enough for most of the Eighth Corps to escape from Rheims and rally beyond the city. The Riazan Regiment itself was cut off but escaped through the city’s back streets with the help of a local royalist guide.16
After defeating Saint-Priest, Napoleon gave his troops two days’ rest at Rheims before heading south to tackle Schwarzenberg. Meanwhile the first three weeks of March had been a time of great tension at allied headquarters, above all for Alexander. The emperor was not without military talent but he was nervous and lacked confidence. His correspondence in March 1814 reveals great fears that history was about to repeat itself. Once again Schwarzenberg was advancing with infuriating caution and slowness at a time when Blücher’s army was running considerable risks. The emperor was constantly attempting to prod Schwarzenberg forward while enquiring anxiously about the safety of Blücher and Saint-Priest, and bemoaning the fact that news from them was so infrequent. On 12 March there were angry scenes at headquarters when Alexander interrogated Metternich about the existence of secret Austrian orders to Schwarzenberg constraining the main army’s movements. Meanwhile Frederick William III shouted out that the Austrians were betraying the allied cause and exposing the Prussian and Russian soldiers of Blücher’s army to destruction. Inevitably, when news arrived of Saint-Priest’s defeat this did nothing to calm Alexander’s fears. Remembering events in February, he was terrified that, once again, Wittgenstein’s Army Corps and Pahlen’s advance guard were isolated and vulnerable to a sudden attack. Langeron recalls that Napoleon’s speed and audacity in February had thrown the allied commanders off balance: ‘We believed that we could see him everywhere.’ Of no one was this more true than Alexander.17
