Campaign in northeastern France The
First Battle of Bar-sur-Aube on 24 January 1814 was an indecisive clash between 20,000 French led by Mortier and the Army of Bohemia's 3rd Corps under
Feldzeugmeister (FZM)
Ignaz Gyulai. At this time, Napoleon arrived at the front and with 36,000 troops attacked Blucher's 28,000 men at the
Battle of Brienne on 29 January. The Allies defeated Napoleon by concentrating 80,000 men against 45,000 French at the
Battle of La Rothière on 1 February. Elated by their victory, the Allies decided to make a two-pronged advance toward Paris. Schwarzenberg's army moved toward
Troyes along the
Seine River, while farther north Blücher pressed forward toward
Meaux along the
Marne River. Napoleon turned against Blücher who had allowed his army to become so strung out, that his advance elements were ahead of his
rearguard. In the
Six Days' Campaign between 10 and 14 February 1814, Napoleon mauled the Army of Silesia. During this period, Blücher's 56,000-strong army suffered 16,000 casualties and lost 47 guns, while French losses numbered only around 4,000. Nevertheless, the Army of Silesia was soon reinforced to a total of 53,000 men. While the Army of Silesia recovered from its drubbing, Napoleon turned against Schwarzenberg, whose advance elements were across the Seine. On 17 February, Napoleon crushed Schwarzenberg's advance guard at the
Battle of Mormant and the next day routed
Crown Prince William of Württemberg at the
Battle of Montereau. This caused Schwarzenberg to retreat and to call Blücher to join him. On 20 February 1814, Schwarzenberg received news that Marshal
Charles-Pierre Augereau's French army in the south was menacing
Geneva and
Besançon. Earlier, the 2nd Corps (Austrian) was detached from the Army of Bohemia to support operations near Switzerland. To face this new threat to his south flank, Schwarzenberg sent the 1st Corps (Austrian) to
Dijon, reducing his army to 90,000 men. Together with Blücher, the Coalition still had 140,000 soldiers to face Napoleon with 75,000, but Schwarzenberg ordered another withdrawal. However, Blücher moved northwest in another lunge at Paris after getting permission to separate from the Army of Bohemia. Since only a scanty force under Marmont and Mortier stood between Blücher and Paris, on 26 February, Napoleon set out in pursuit of the Army of Silesia. There was a clash at the
Battle of Gué-à-Tresmes at the end of February 1814. Napoleon pursued Blücher north across the
Aisne River where the troops of Wintzingerode and Bülow joined the Army of Silesia. This reinforcement gave Blücher 110,000 troops against the 48,000 French opposed to him. After the
Battle of Craonne on 7 March, Napoleon attacked Blücher at the
Battle of Laon on 9–10 March and was defeated. Next, Napoleon rapidly switched his forces to oppose an Allied corps under GL
Guillaume Emmanuel Guignard, vicomte de Saint-Priest that had captured
Reims. On 13 March, Napoleon's forces attacked the Allies in the
Battle of Reims, killing Saint-Priest and routing his corps. While Napoleon was tilting with Blücher in the north, Schwarzenberg's host slowly advanced, beating the French at the Second
Battle of Bar-sur-Aube on 26–27 February 1814 and the
Battle of Laubressel on 3–4 March. Napoleon now turned against Schwarzenburg, who paused his advance after hearing the news of Reims. Thinking he had Schwarzenberg on the run, Napoleon found himself involved in the
Battle of Arcis-sur-Aube on 20–21 March when his normally cautious opponent decided to fight. Enjoying a numerical superiority of 80,000 to only 28,000 French, the Allies defeated Napoleon, though they failed to pursue. The French emperor moved east to cut the Army of Bohemia's supply line and to add the garrisons of
Verdun and
Metz to his army. Emperor
Francis I of Austria at
Bar-sur-Aube fled to Dijon and missed being captured by French cavalry by only a few hours.
Defenses of Paris Since the disaster in Russia and the start of the war, the French populace had become increasingly war-weary. Napoleon felt that fortifying his own capital would make him look weak in the eyes of the French population. Joseph Bonaparte was responsible for defending Paris, but because of his shortcomings, military organization and administration was poor. Marshal
Bon-Adrien Jeannot de Moncey was in charge of the
National Guard. There were also some regular army units and
Imperial Guard reserves. In January 1814, a plan was proposed to fortify Paris with earthworks, but it was rejected by Napoleon. Later, 56 wooden barricades were built to deter cavalry raids. These were armed with 40
4-pounder guns and 20
8-pounder guns. The rejected fortification plan was revived, but Joseph insisted on delaying it until it could be approved by Napoleon. Because of this, Paris remained virtually unfortified. Meanwhile,
Charles Maurice de Talleyrand-Périgord was at Paris, intriguing against Napoleon.
Tsar Alexander's initiative The Allies captured an uncoded message from Napoleon to his empress. It read, "I have decided to move on to the Marne in order to push the enemy's armies farther from Paris and to draw myself nearer my fortresses." An intercepted message from Chief of Police
Jean René Savary to Napoleon stated that Paris' magazines were empty and its population was demanding peace. Tsar Alexander read the captured dispatches and realized that the proper objective was Paris. He asked the opinions of Generals
Michael Andreas Barclay de Tolly,
Hans Karl von Diebitsch, and
Karl Wilhelm von Toll. Barclay de Tolly wanted to follow Napoleon. Diebitsch wanted to send 40,000 or 50,000 men to Paris and follow Napoleon with the remainder. Toll argued for advancing on Paris with most of the armies while sending 10,000 cavalry under Wintzingerode after Napoleon as a diversion. Since Toll's opinion matched what Alexander believed, the King of Prussia and Schwarzenberg were convinced to accept this strategy. Orders were also sent to Blücher to cooperate in the march on Paris. Marmont and Mortier did not realize that the Army of Bohemia was advancing directly toward them. On 25 March 1814, their 19,000 soldiers encountered Coalition forces in the
Battle of Fère-Champenoise and were badly beaten, suffering 6,000 casualties and losing 45 guns. In addition, a nearby French force of 4,300 men and 16 guns under
General of Division (GD)
Michel-Marie Pacthod was surrounded and wiped out. Blocked from retreating directly to Meaux by part of Blücher's army, the forces of Marmont and Mortier managed to escape to Paris via
Provins. Meanwhile, Napoleon won a useless victory over Wintzingerode's 10,000 horsemen in the
Battle of Saint-Dizier on 26 March. By the next day, Napoleon realized that his opponents had a three-day lead in the race for Paris. He ordered the army to march to Paris via Troyes.
Empress Marie Louise and her son
Napoleon II left Paris on 29 March and traveled south. ==Forces==
