On 18 February 1814, Napoleon defeated Crown Prince Fredrick William of Württemberg in the Battle of Montereau.
After this setback the Austrian general Karl Philipp, Prince of Schwarzenberg ordered the Army of Bohemia to retreat to Troyes.
Schwarzenberg also asked his ally Gebhard Leberecht von Blücher to support his northern flank at Méry-sur-Seine and the Prussian general immediately complied.
The Austrian intended to fight a battle on 21–22 February near Troyes.
However, bad news from his commander in the south, Prince Frederick VI of Hesse-Homburg soon changed his mind.
Marshal Pierre Augereau threatened to recapture Chalon-sur-Saône while Jean Gabriel Marchand menaced Geneva.
Schwarzenberg ordered Vincenzo Federico Bianchi to take the Austrian I Corps and a reserve division and march to Dijon where they would join Hesse-Homburg's command.

At Troyes, Schwarzenberg's 90,000 troops and Blücher's 50,000 faced about 75,000 soldiers under Napoleon.
Though he outnumbered the French emperor by nearly two-to-one, Schwarzenberg's intelligence services consistently overestimated enemy strength.
His troops had worn-out uniforms and were short of food in an area that had been stripped of supplies by both armies.
On 22 February the French probed the Allied positions from Méry to Troyes.
Marshal Nicolas Oudinot's infantry cleared Méry of Allied troops and gained a foothold on the far bank, but they could not hold it against Allied counterattacks.
In this clash, 3,600 men from Pierre François Joseph Boyer's division fought against 5,000 Russians from Alexei Grigorievich Scherbatov's VI Infantry Corps of Fabian Wilhelm von Osten-Sacken's command and 1,200 Prussians from Ludwig Yorck von Wartenburg's I Corps.
That night Schwarzenberg directed his army to withdraw behind the Seine River, except for Ignaz Gyulai's III Corps, which would move southeast to Bar-sur-Seine.

Disappointed that his Austrian colleague refused to give battle, Blücher asked for and received permission to operate independently.
He hoped to rendezvous with two corps under Ferdinand von Wintzingerode and Friedrich Wilhelm Freiherr von Bülow, and thus reinforced, advance on Paris by a more northerly route.
Meanwhile, on 23 February Schwarzenberg's army fell back eastward covered by a rearguard under the Bavarian general Karl Philipp von Wrede.
The Allies sent an emissary to Napoleon to propose a truce, but nothing came of this effort when the emperor's conditions proved unacceptable.
Near Troyes, the 1,290 horsemen of Auguste Jean Ameil's 12th Light Cavalry Brigade and the 21st and 26th Dragoons clashed with Moritz von Liechtenstein's Austrian 2nd Light Division.
The Austrian cavalry lost 311 men and three of their jäger companies were captured.

In its withdrawal, Schwarzenberg's main body passed through Vendœuvres while other columns went via Piney on the north and Bar-sur-Seine on the south.
In pursuit, Napoleon sent Étienne Maurice Gérard and the II Corps toward Vendœuvres and Marshal Jacques MacDonald and the XI Corps to Bar-sur-Seine.
The French emperor held his reserves near Troyes so that he might react to Blücher's moves.
On 26 February, Oudinot's troops occupied Bar-sur-Aube while MacDonald moved southeast to seize Mussy-sur-Seine.
The next morning, Napoleon finally received reports that Blücher's army was advancing on Paris and had gained a 3-day head start.
