1814 campaign in north-east France

The 1814 campaign in north-east France was Napoleon's final campaign of the War of the Sixth Coalition. Following their victory at Leipzig (1813), Russian, Austrian and German armies of the Sixth Coalition entered France. Despite the disproportion of the forces in favour of the Coalition, Napoleon managed to inflict many defeats, especially during the Six Days Campaign. However, the Coalition kept heading towards Paris, which capitulated in March 1814. As a result, Napoleon was deposed and exiled to Elba and the victorious powers started to redraw the map of Europe during the First Treaty of Paris and during the early stages of the Congress of Vienna. A Seventh Coalition was formed the next year after Napoleon's escape from Elba and return to power.

Background
Following defeats in the Wars of the Fourth and Fifth Coalition, Prussia an Austria were forcibly allied with France during the Russian Campaign. When this campaign resulted in the destruction of Napoleon's Grande Armée, Prussia and Austria took advantage of this situation by forming a Sixth Coalition against France. The retreat from Russia turned into a new war on German soil, where Napoleon was decisively defeated at Leipzig. Most European countries then turned against Napoleon and started to invade France.

Strategic Situation


When the last of the French troops had crossed to the western bank of the Rhine, divided counsels made their appearance at the headquarters of the Coalition members. Every one was weary of the war, and many felt that it would be unwise to push Napoleon and the French nation to extremes. Hence a prolonged halt arose, utilized by the troops in renewing their equipment and so forth, but ultimately the Young German party, led by Blücher and the principal fighting men of the army, triumphed. The Coalition forces started to cross the Rhine with a three-part force,:
 * The Army of Bohemia or the Grand Army, with 200,000–210,000 Austrian soldiers under Prince Schwarzenberg, passed through Swiss territory and crossed the Rhine between Basel and Schafhausen on 20 December 1813.
 * The Army of Silesia, with 50,000–75,000 Prussians and Russians under Prince Blücher, crossed the Rhine between Rastadt and Koblenz on 1 January 1814.
 * The Army of the North, of about 120,000 men, with Prussian and Russian corps under the command of Wintzingerode and Bülow, and Dutch troops under Prince Bernadotte, was to move in support on the right flank through the Netherlands and Laon (in the Picardy region in northern France); this force was not yet ready and did not, in fact, reach the latter place until March.

To meet these forces Napoleon, by the senatus consultum of the 9 October 1813, had to draft anticipatively the conscripts from 1814 and 1815. These very young and unexperienced recruits formed the bulk of the new French Army and were nicknamed the Marie-Louise, in honour of the young Empress Marie-Louise.

However, he could not collect 200,000 men in all, of whom upwards of 100,000 were held by the Duke of Wellington on the Spanish frontier (see Invasion of south-west France), and 20,000 more were required to watch the debouches from the Alps. Hence less than 80,000 remained available for the east and north-eastern frontier. If, however, he was weak in numbers, he was now again operating in a friendly country, able to find food almost everywhere and else practically indifferent as to his communications.

Campaign


Napoleon attempted to counter the incursion of the Army of Silesia shortly after their crossing but arrived too late, and engaged in pursuit. On 25 January Blücher entered Nancy, and, moving rapidly up the valley of the Moselle, was in communication with the Austrian advanced guard near La Rothière on the afternoon 28 January.

On 29 January Napoleon caught up with Blücher and attacked. Blücher's headquarters were surprised and he himself nearly captured by a sudden rush of French troops (Battle of Brienne), learning at the same time that the emperor in person was at hand. Blücher accordingly fell back a few miles next morning to a strong position covering the exits from the Bar-sur-Aube defile. There he was joined by the Austrian advance guard and together they decided to accept battle—indeed they had no alternative, as the roads in rear were so choked with traffic that retreat was out of the question. About noon on 2 February Napoleon engaged them in battle of La Rothière; but the weather was terrible, and the ground so heavy that his favourite artillery, the mainstay of his whole system of warfare, was useless and in the drifts of snow which at intervals swept across the field, the columns lost their direction and many were severely handled by the Cossacks. At nightfall the fighting ceased and the emperor retired to Lesmont, and thence to Troyes, Marshal Marmont being left to observe the enemy.

Vauchamps


Owing to the state of the roads, more perhaps to the extraordinary lethargy which always characterized Schwarzenberg's headquarters, no pursuit was attempted. But on 4 February Blücher, chafing at this inaction, obtained the permission of his own sovereign, King Frederick III Prussia, to transfer his line of operations to the valley of the Marne; Pahlen's corps of Cossacks were assigned to him to cover his left and maintain communication with the Austrians.

Believing himself secure behind this screen, he advanced from Vitry along the roads leading down the valley of the Marne, with his columns widely separated for convenience of subsistence and shelter the latter being almost essential in the terrible weather prevailing. Blücher himself on the night of 7/8 February was at Sézanne, on the exposed flank so as to be nearer to his sources of intelligence, and the rest of his army were distributed in four small corps at or near Épernay, Montmirail and Étoges; reinforcements also were on their way to join him and were then about Vitry.

In the night his headquarters were again surprised, and Blücher learnt that Napoleon himself with his main body was in full march to fall on his scattered detachments. At the same time he heard that Pahlen's Cossacks had been withdrawn forty-eight hours previously, thus completely exposing his flank. He himself retreated towards Étoges endeavouring to rally his scattered detachments.

Napoleon was too quick for Blücher he decimated Lieutenant General Olssufiev's Russian IX Corps at the Battle of Champaubert (10 February). This placed his army between Blücher's vanguard and his main body. Napoleon turned his attention to the vanguard and defeated Osten-Sacken and Yorck at Montmirail on the 11 February; and attacked and defeated them again the next day at the Battle of Château-Thierry. Napoleon then turned on the main body of the Army of Silesia and on the 14 February defeated Blücher in Battle of Vauchamps near Étoges, pursuing the latter towards Vertus. These disasters compelled the retreat of the whole Silesian army, and Napoleon, leaving detachments with marshals Mortier and Marmont to deal with them, hurried back to Troyes.

Napoleon with his main body struck at the flank of Schwarzenberg's Austrian army, which had meanwhile begun its leisurely advance, and again at Mormant (17 February), Montereau (18 February) and Méry (21 February), he inflicted such heavy punishment upon his adversaries that they fell back precipitately to Bar-sur-Aube.

Laon
In the meantime Blücher had rallied his scattered forces and was driving Marmont and Mortier before him. Napoleon, as soon as he had neutralised Schwarzenberg, counter-marched his main body and moving again by Sézanne, fell upon Blücher's left and drove him back upon Soissons. This place had been held by a French garrison, that had capitulated only twenty-four hours beforehand, a fact of which Napoleon was unaware. The Silesian army was thus able to escape, and marching northwards combined with Bernadotte's Army of the North at Laon—this reinforcement bringing the forces at Blücher's disposal up to over 100,000 men.

On 7 March Napoleon fell upon the advance guard of this force at the Battle of Craonne and drove it back upon Laon, where the Battle of Laon took place on 9 March. Napoleon was here defeated, and with only 30,000 men at his back, retreated to Soissons. On hearing that Rheims had fallen to a Coalition corps under the command of the Russian General Vicomte de Saint-Priest, Napoleon crossed in front of Blücher's command and on 13 March retook Rheims during which Saint-Priest was mortally wounded.

Arcis-sur-Aube
On 14 March, Schwarzenberg, becoming aware of Napoleon's presence in Reims, began again his advance and his advanced guard had reached Arcis-sur-Aube, when Napoleon intercepted it on 20 March. At the start of the Battle of Arcis-sur-Aube, the Austrians were about 21,000 strong while the French fielded 20,000, however during the night of 20/21 both sides received reinforcements. On the second day of the battle while French strength was about 28,000 the Austrians now deployed 80,000. This forced the issue and while French losses were less than the Austrians, Napoleon was forced to withdraw eastwards and Schwarzenberg was free to advance west.

Coalition armies march on Paris
Thus after six weeks fighting the Coalition armies were hardly more advanced than at the beginning. The Coalition generals still hoped to bring Napoleon to battle against their combined forces, however after Arcis-sur-Aube Napoleon realising that he could no longer continue with his current strategy of defeating the Coalition armies in detail, decided to change his tactics. He had two options, he could fall back on Paris and hope that the Coalition members would come to terms as capturing Paris with a French army under his command would be difficult and time consuming; or he could copy the Russians and leave Paris to his enemies (as they had left Moscow to him two years earlier). He decided to move eastward to Saint-Dizier, rally what garrisons he could find, and raise the whole country against the invaders. He had actually started on the execution of this plan when a letter to Empress Marie-Louise outlining his intention to move on the Coalition lines of communications was intercepted by Cossacks in Blücher's army on 22 March and hence his projects were exposed to his enemies.

The Coalition commanders held a council of war at Pougy on the 23 March and initially decided to follow Napoleon, but the next day Tsar Alexander I of Russia and King Frederick of Prussia along with their advisers reconsidered, and realising the weakness of their opponent (and perhaps actuated by the fear that Duke of Wellington from Toulouse might, after all, reach Paris first), decided to march to Paris (then an open city), and let Napoleon do his worst to their lines of communications.

The Coalition armies marched straight for the capital. Marmont and Mortier with what troops they could rally took up a position on Montmartre heights to oppose them. The Battle of Paris (1814) ended when the French commanders, seeing further resistance to be hopeless, gave way on 31 March, just as Napoleon, with the wreck of the Guards and a mere handful of other detachments, was hurrying across the rear of the Austrians towards Fontainebleau to join them.

Results


On 2 April, the French Senate agreed to the Coalition's terms and passed a resolution deposing Napoleon (Acte de déchéance de l'Empereur). They also passed a decree dated 5 April, justifying their actions. Napoleon had advanced as far as Fontainebleau when he learned that Paris had surrendered. When Napoleon proposed the army march on the capital, his marshals decided to mutiny. On 4 April, Napoleon abdicated in favour of his son, with Marie-Louise as regent. However, the Coalition refused to accept this. Napoleon was then forced to announce his unconditional abdication on the 6 April, and a few days later on 13 April under the terms of the Treaty of Fontainebleau Napoleon accepted a pension for his relatives and exile for himself to the island Elbe. Louis XVIII was restored to the French throne, but under certain conditions including that of the establishment of a French Parliament.

Aftermath
On 5 of May—two days after Napoleon set sail on the British brig of war HMS Undaunted, bound for his new realm of Elba—the treaty of Treaty of Paris (1814) was signed by Louis XVIII's plenipotentiaries and the major Coalition powers. France was stripped of most of her territorial gains, and reduced to its borders of November 1792. In addition, although she kept some of her colonies she Tobago, Santa Lucia and Mauritius. The treaty was quite lenient (compared to the treaty which was imposed oh her the following year Treaty of Paris (1815)). As for the difficult question as to how the map of Europe should be redrawn, that was postponed by common consent, to be decided at the Congress of Vienna to be held in the autumn.

The Coalition powers hoped, that by granting this lenient peace, France might be welcomed back to become a cooperating member of the European nations, but the Napoleonic Wars were not over for the very next year Napoleon escaped from Elba and returned to France, he was opposed by the powers of the Seventh Coalition who defeated his army at Waterloo, re-invaded the country and forced him to abdicate for a second and final time.
