Battle Of Montmirail

The Battle of Montmirail (11 February 1814) was fought between a French force led by Emperor Napoleon and two Allied corps commanded by Fabian Wilhelm von Osten-Sacken and Ludwig Yorck von Wartenburg. In hard fighting that lasted until evening, French troops including the Imperial Guard defeated Sacken's Russian soldiers and compelled them to retreat to the north. Part of Yorck's Prussian I Corps tried to intervene in the struggle but it was also driven off. The battle occurred near Montmirail, France, during the Six Days Campaign of the Napoleonic Wars. Montmirail is located east of Meaux.

After Napoleon crushed Zakhar Dmitrievich Olsufiev's small isolated corps in the Battle of Champaubert on 10 February, he found himself in the midst of Gebhard Leberecht von Blücher's widely-spread Army of Silesia. Leaving a small force in the east to watch Blücher, Napoleon turned the bulk of his army to the west in an attempt to destroy Sacken. Unaware of the size of Napoleon's army, Sacken tried to smash his way east to join Blücher. The Russians managed to hold their ground for several hours, but were forced back as more and more French soldiers appeared on the battlefield. Yorck's troops belatedly arrived only to be repulsed, but the Prussians distracted the French long enough to allow Sacken's Russians to join them in a withdrawal to the north. The following day would see the Battle of Château-Thierry as Napoleon launched an all-out pursuit.

Background

On the 1st of February 1814, Prussian Field Marshal Gebhard Leberecht von Blücher commanding 80,000 Allied soldiers from his own Army of Silesia and Austrian field marshal Karl Philipp, Prince of Schwarzenberg's Army of Bohemia defeated Napoleon with 45,000 French troops in the Battle of La Rothière. Elated by their triumph, the Allied commanders devised a new plan whereby Schwarzenberg advanced from Troyes toward Paris while Blücher operated on a more northerly axis from Châlons-sur-Marne toward Meaux. The two armies would be linked by Peter Wittgenstein's corps and a scouting force led by Alexander Nikitich Seslavin. Within a few days the cautious Schwarzenberg began pulling Wittgenstein's troops to the south. Believing the war was almost over, Blücher pressed rapidly west after a smaller French force under Marshal Jacques MacDonald. Unknown to the Prussian field marshal, on 5 February Schwarzenberg switched Seslavin's force from the right flank to the extreme left flank without informing Blücher. Since he lacked a liaison officer with Seslavin, the Prussian was unaware that a dangerous gap yawned on his left flank.

Until 6 February, Napoleon planned to strike a blow against the Army of Bohemia. But that day the French emperor received intelligence that Blücher was moving on Paris, via Meaux. Since MacDonald was too weak to stop Army of Silesia, Napoleon was compelled to deal with Blücher first. While sending out patrols to determine the precise whereabouts of the Prussian field marshal's army, Napoleon sent Marshal Auguste de Marmont with 8,000 troops to Sézanne. On 8 February these were joined by part of the Imperial Guard and a large force of cavalry. On the same day MacDonald's patrols reported that Ludwig Yorck von Wartenburg was near Épernay with 18,000 men. When, on the morning of 9 February, Napoleon received news from Marmont that Fabian Wilhelm von Osten-Sacken was near Montmirail with about 15,000 troops, the French army lurched into action.

Marshal Claude Perrin Victor with 14,000 men, consisting of his own corps, a force under Etienne Maurice Gérard and cavalry, would hold Nogent-sur-Seine. Marshal Nicolas Oudinot with 20,000 men including the newly formed VII Corps, a 5,000-man Young Guard division, National Guards and a cavalry force under Pierre Claude Pajol was instructed to guard the bridges at Bray-sur-Seine, Montereau, Pont-sur-Yonne and Sens. At this time, Napoleon had only 70,000 soldiers to confront about 200,000 Allies. With Victor and Oudinot watching Schwarzenberg, Napoleon decided to act against Blücher who he assumed to have 45,000 troops.

In fact, the Army of Silesia had 57,000 soldiers, including 18,000 under Yorck at Château-Thierry, 20,000 under Sacken near La Ferté-sous-Jouarre and 19,000 under Zakhar Dmitrievich Olsufiev, Peter Mikhailovich Kaptzevich and Friedrich von Kleist at Champaubert, Vertus and Bergères-lès-Vertus. However, Blücher's army was spread across a front of and Napoleon might count on the help of the 10,000 men under MacDonald. Napoleon striking force numbered 30,000 men and 120 guns. It consisted of Marmont's corps, two Young Guard divisions led by Marshal Michel Ney, the I Cavalry Corps, two Old Guard divisions under Marshal Édouard Mortier, duc de Trévise, part of the Guard Cavalry and Jean-Marie Defrance's independent cavalry division. Mortier was ordered to bring up the rear.

Fearing that Napoleon would offer battle near Nogent, Schwarzenberg asked his colleague Blücher to send Kleist's corps south to help. Obligingly, the Prussian field marshal ordered Kleist, Kaptzevich and Olsufiev to converge on Sézanne on 10 February. Riding with Kleist and Kaptzevich, Blücher led them south from Vertus toward Fère-Champenoise, planning to turn west from there to Sézanne. After days of rain, the roads were swamped, but the French country people assisted the army in dragging Napoleon's cannons through the mud. The French army fell on Olsufiev's small corps with crushing force in the Battle of Champaubert on 10 February. With only 5,000 men and 24 guns, the Russian general unwisely held his ground; Olsufiev ended the day as a French prisoner and his corps was nearly destroyed. The 1,500 survivors were formed into three or four ''ad hoc'' battalions.

Advance to contact

Blücher was near Fère-Champenoise when heard that Olsufiev's corps had been wrecked; he immediately ordered Kleist and Kaptzevich to undertake a night march back to Vertus. The Prussian field marshal ordered Yorck to march to Montmirail while holding the important bridge over the Marne River at Château-Thierry in case a retreat was necessary. During 10 February, Sacken advanced west to Trilport where there was a bridge over the Marne. Blücher recalled Sacken, instructing him to march east to Montmirail to rendezvous with Yorck, then clear the highway between there and Vertus. Blücher neglected to mention anything to Sacken about escaping over the Marne.

Napoleon ordered MacDonald to move east from Trilport. At 7:00 pm, the emperor instructed Étienne Marie Antoine Champion de Nansouty with two divisions of cavalry to march west to capture Montmirail, followed at 3:00 am by Étienne Pierre Sylvestre Ricard's division of Marmont's corps. Ney's Young Guard divisions would move in their wake at 6:00 am while Mortier's Old Guard would march directly from Sézanne to Montmirail. Jean François Leval's division was detached from Oudinot and ordered to march to Montmirail via La Ferté-Gaucher. Napoleon posted Marmont at Étoges with Joseph Lagrange
