Waterloo campaign

The Waterloo campaign (15 June – 8 July 1815) was fought between the French Army of the North and two Seventh Coalition armies, an Anglo-allied army and a Prussian army. Initially the French army had been commanded by Napoleon Bonaparte, but he left for Paris after the French defeat at the Battle of Waterloo. Command then rested on Marshals Soult and Grouchy, who were in turn replaced by Marshal Davout, who took command at the request of the French Provisional Government. The Anglo-allied army was commanded by the Duke of Wellington and the Prussian army by Field Marshall Graf von Blücher.

The war between France and the Seventh Coalition came when the other European Great Powers refused to recognise Napoleon as Emperor of the French upon his return from exile on the island of Elba, and declared war on him, rather than France, as they still recognised Louis XVIII as the king of France and considered Napoleon a usurper. Rather than wait for the Coalition to invade France, Napoleon decided to attack his enemies and hope to defeat them in detail before they could launch their combined and coordinated invasion. He chose to launch his first attack against the two Coalition armies cantoned in modern-day Belgium, then part of the newly formed United Kingdom of the Netherlands, but until the year before part of the First French Empire.

Hostilities started on 15 June when the French drove in the Prussian outposts and crossed the river Sambre at Charleroi placing their forces between the cantonment areas of Wellington's army (to the west) and Blücher's army to the east. On 16 June the French prevailed with Marshal Ney commanding the left wing of the French army holding Wellington at the Battle of Quatre Bras and Napoleon defeating Blücher at the Battle of Ligny. On 17 June, Napoleon left Grouchy with the right wing of the French army to pursue the Prussians while he took the reserves and command of the left wing of the army to pursue Wellington towards Brussels.

On the night of 17 June the Anglo-allied army turned and prepared for battle on a gentle escarpment, about 1 mi south of the village of Waterloo. The next day the Battle of Waterloo proved to be the decisive battle of the campaign. The Anglo-allied army stood fast against repeated French attacks, until with the aid of several Prussian corps that arrived at the east side of the battlefield in the early evening they managed to rout the French army. Grouchy with the right wing of the army engaged a Prussian rearguard at the simultaneous Battle of Wavre, and although he won a tactical victory his failure to prevent the Prussians marching to Waterloo meant that his actions contributed to the French defeat at Waterloo. The next day (19 June) he left Wavre and started a long retreat back to Paris.

After the defeat at Waterloo, Napoleon chose not to remain with the army and attempt to rally it, but returned to Paris to try to secure political support for further action. He failed to do so, and was forced to abdicate on 22 June. Two days later, a Provisional Government took over French politics. Meanwhile, the two Coalition armies hotly pursued the French army to the gates of Paris, during which the French on occasion turned and fought some delaying actions, in which thousands of men were killed.

Initially the remnants of the French left wing and the reserves that were routed at Waterloo were commanded by Marshal Soult while Grouchy kept command of the right wing. However, on 25 June Soult was relieved of his command by the Provisional Government and was replaced by Grouchy, who in turn was placed under the command of Davout.

When the French Provisional Government realised that the French army under Marshal Davout was unable to defend Paris, they authorised delegates to accept capitulation terms which led to the Convention of St. Cloud (the surrender of Paris) which ended hostilities between France and the armies of Blücher and Wellington.

The two Coalition armies entered Paris on 7 July. The next day Louis XVIII was restored to the French throne, and a week later on 15 July Napoleon surrendered to Captain Frederick Lewis Maitland of HMS Bellerophon (1786). Napoleon was exiled to the island of Saint Helena where he died on 5 May 1821.

Under the terms of the peace treaty of November 1815, Coalition forces remained in Northern France as an army of occupation under the command of the Duke of Wellington.

Prelude
Napoleon returned from his exile on the island of Elba on 1 March 1815, King Louis XVIII fled Paris on 19 March, and Napoleon entered Paris the next day. Meanwhile, far from recognising him as Emperor of the French, the Great Powers of Europe (Austria, Great Britain, Prussia and Russia) and their allies, who were assembled at the Congress of Vienna, declared Napoleon an outlaw, and with the signing of this declaration on 13 March 1815, so began the War of the Seventh Coalition. The hopes of peace that Napoleon had entertained were gone – war was now inevitable. A further treaty (the Treaty of Alliance against Napoleon) was ratified on 25 March in which each of the Great European Powers agreed to pledge 150,000 men for the coming conflict. Such a number was not possible for Great Britain, as her standing army was smaller than the three of her peers. Besides, her forces were scattered around the globe, with many units still in Canada, where the War of 1812 had recently ceased. With this in mind she made up her numerical deficiencies by paying subsidies to the other Powers and to the other states of Europe that would contribute contingents.

Some time after the allies began mobilising, it was agreed that the planned invasion of France was to commence on 1 July 1815, much later than both Blücher and Wellington would have liked as both their armies were ready in June, ahead of the Austrians and Russians; the latter were still some distance away. The advantage of this later invasion date was that it allowed all the invading Coalition armies a chance to be ready at the same time. Thus they could deploy their combined numerically superior forces against Napoleon's smaller, thinly spread forces, thus ensuring his defeat and avoiding a possible defeat within the borders of France. Yet this postponed invasion date allowed Napoleon more time to strengthen his forces and defences, which would make defeating him harder and more costly in lives, time and money.

Napoleon now had to decide whether to fight a defensive or offensive campaign. Defence would entail repeating the 1814 campaign in France but with much larger numbers of troops at his disposal. France's chief cities, Paris and Lyon, would be fortified and two great French armies, the larger before Paris and the smaller before Lyon, would protect them; francs-tireurs would be encouraged, giving the Coalition armies their own taste of guerrilla warfare.

Napoleon chose to attack, which entailed a pre-emptive strike at his enemies before they were all fully assembled and able to co-operate. By destroying some of the major Coalition armies, Napoleon believed he would then be able to bring the governments of the Seventh Coalition to the peace table to discuss results favourable to himself, namely peace for France with himself remaining in power as its head. If peace were rejected by the allies despite any pre-emptive military success he might have achieved using the offensive military option available to him, then the war would continue and he could turn his attention to defeating the rest of the Coalition armies.

Napoleon's decision to attack in Belgium was supported by several considerations. First, he had learned that the British and Prussian armies were widely dispersed and might be defeated in detail. The other major coalition armies of Russia and Austria would not be able to reinforce the Prussians and British. This was because the Russian army was still moving across Europe and the Austrian army was still mobilising. Also, the British troops in Belgium were largely second-line troops; most of the veterans of the Peninsular War had been sent to America to fight the War of 1812. In addition, the army of the United Netherlands was reinforcing the British. These Dutch troops were ill-equipped and inexperienced. And, politically, a French victory might trigger a pro-French revolution in French-speaking Belgium.

French forces


During the Hundred Days both the Coalition nations and Napoleon mobilised for war. Upon resumption of the throne, Napoleon found that he was left with little by Louis XVIII. There were 56,000 soldiers of which 46,000 were ready to campaign. By the end of May the total armed forces available to Napoleon had reached 198,000 with 66,000 more in depots training but not yet ready for deployment.

Napoleon placed some corps of his armed forces at various strategic locations as armies of observations. Napoleon split his forces into three main armies; first, he placed an army in the south near the Alps. This army was to stop Austrian advances in Italy. Second, there was an army on the French/Prussian border where he hoped to defeat any Prussians attacks. Last, the L'Armee du Nord was placed on the border with the United Netherlands to defeat the British, Dutch and Prussian forces if they dared to attack. (see Military mobilisation during the Hundred Days). Lamarque led the small Army of the West into La Vendée to quell a Royalist insurrection in that region.

By the end of May Napoleon had formed L'Armée du Nord (the "Army of the North") which, led by himself, would participate in the Waterloo campaign and had deployed the corps of this army as follows:
 * I Corps (D'Erlon) cantoned between Lille and Valenciennes.
 * II Corps (Reille) cantoned between Valenciennes and Avesnes.
 * III Corps (Vandamme) cantoned around Rocroi.
 * IV Corps (Gérard ) cantoned at Metz.
 * VI Corps (Lobau) cantoned at Laon.
 * I, II, III, and IV Reserve Cavalry Corps (Grouchy) cantoned at Guise.
 * Imperial Guard (Mortier) at Paris.

Once the campaign was underway Napoleon, on the evening of 15 June, would send Marshal Ney with the left wing of the army (I and II corps) to face Wellington at Quatre Bras. During the morning of 17 June Napoleon detached the right wing (III and IV corps) under Marshal Grouchy to pursue the retreating Prussians (who retreated to Wavre), while he led the reserves (Imperial Guard, VI Corps, and I, II, III, and IV Cavalry Corps) to rejoin Ney's detachment and pursue Wellington to Waterloo.

Coalition forces
In the early days of June 1815, Wellington and Blücher's forces were disposed as follows:

Wellington's Anglo-allied army of 93,000 with headquarters at Brussels were cantoned:
 * I Corps (Prince of Orange), 30,200, headquarters Braine-le-Comte, disposed in the area Enghien-Genappe-Mons.
 * II Corps (Lord Hill), 27,300, headquarters Ath, distributed in the area Ath-Oudenarde-Ghent.
 * Reserve cavalry (Lord Uxbridge) 9,900, in the valley of the Dendre river, between Geraardsbergen and Ninove.
 * The reserve (under Wellington himself) 25,500, lay around Brussels.
 * The frontier in front (to the west) of Leuze to Binche was watched by Dutch light cavalry.

Blücher's Prussian army of 116,000 men, with headquarters at Namur, was distributed as follows:
 * I Corps (Graf von Zieten), 30,800, cantoned along the Sambre, headquarters Charleroi, and covering the area Fontaine-l'Évêque-Fleurus-Moustier.
 * II Corps (Pirch I), 31,000, headquarters at Namur, lay in the area Namur-Hannut-Huy.
 * III Corps (Thielemann), 23,900, in the bend of the river Meuse, headquarters Ciney, and disposed in the area Dinant-Huy-Ciney.
 * IV Corps (Bülow), 30,300, with headquarters at Liège and cantoned around it.

The frontier in front of Binche, Charleroi and Dinant was watched by the Prussian outposts.

Thus the Coalition front extended for nearly 90 mi across what is now Belgium, and the mean depth of their cantonments was 30 mi. To concentrate the whole army on either flank would take six days, and on the common centre, around Charleroi, three days.

Start of hostilities (15 June)
Napoleon moved the 128,000 strong Army of the North up to the Belgian frontier in relative secrecy, and crossed the frontier at Thuin near Charleroi on 15 June 1815. The French drove in Coalition outposts and secured Napoleon's favoured "central position" – at the junction between Wellington's army to his north-west, and Blücher's Prussians to his north-east. Wellington had expected Napoleon to try to envelop the Coalition armies by moving through Mons and to the west of Brussels. Wellington feared that such a move would cut his communications with the ports he relied on for supply. Napoleon encouraged this view with misinformation. Wellington did not hear of the capture of Charleroi until 15:00, because a message from Wellington's intelligence chief, Colquhoun Grant, was delayed by General Dörnberg. Confirmation swiftly followed in another message from the Prince of Orange. Wellington ordered his army to concentrate around the divisional headquarters, but was still unsure whether the attack in Charleroi was a feint and the main assault would come through Mons. Wellington only determined Napoleon's intentions with certainty in the evening, and his orders for his army to muster near Nivelles and Quatre Bras were sent out just before midnight.

The Prussian General Staff seem to have divined the French army's intent rather more accurately. The Prussians were not taken unawares. General Zieten noted the number of campfires as early as 13 June and Blücher began to concentrate his forces.

Napoleon considered the Prussians the greater threat and so moved against them first with the right wing of the Army of the North and the Reserves. Graf von Zieten's I Corps rearguard action on 15 June held up Napoleon's advance, giving Blücher the opportunity to concentrate his forces in the Sombreffe position, which had been selected earlier for its good defensive attributes. Napoleon placed Marshal Ney in command of the French left wing and ordered him to secure the crossroads of Quatre Bras towards which Wellington was hastily gathering his dispersed army. Ney's scouts reached Quatre Bras that evening.

Quatre Bras
Ney, advancing on 16 June, found Quatre Bras lightly held by Dutch troops of Wellington's army. Despite outnumbering the Anglo-allies heavily throughout the day, Ney fought a cautious and desultory battle which failed to capture the crossroads. By the middle of the afternoon Wellington had taken personal command of the Anglo-allied forces at Quatre Bras. The position was reinforced steadily throughout the day as Anglo-allied troops converged on the crossroads. The battle ended in a tactical draw. The next day the Allies ceded the field at Quatre Bras to consolidate their forces on more favourable ground to the north along the road to Brussels as a prelude to the Battle of Waterloo.

Ligny
Napoleon, meanwhile, used the right wing of his army and the reserve to defeat the Prussians, under the command of General Blücher, at the Battle of Ligny on the same day. The Prussian centre gave way under heavy French attack but the flanks held their ground. Several heavy Prussian cavalry charges proved enough to discourage French pursuit. Indeed, they would not pursue the Prussians until the morning of 18 June. D'Erlon's I Corps wandered between both battles contributing to neither Quatre Bras nor to Ligny. Napoleon wrote to Ney warning him that allowing D'Erlon to wander so far away had crippled his attacks on Quatre Bras. However, he made no move to recall D'Erlon when he could easily have done so. The tone of his orders shows that he believed he had things well in hand at Ligny without assistance (as in fact he had).

Interlude (17 June)
After the fighting at Quatre Bras the two opposing commanders Ney and Wellington initially held their ground while they obtained information about what had happened at the larger Battle of Ligny.

With the defeat of the Prussians Napoleon still had the initiative, for Ney's failure to take the Quatre Bras cross roads had actually placed the Anglo-allied army in a precarious position. Ney, reinforced by D'Erlon's fresh corps, lay in front of Wellington, and Ney could have fastened upon the Anglo-allied army and held it in place during the early morning of 17 June, sufficiently long to allow Napoleon to close round his foe's open left flank and deal him a deathblow.

But it did not happen because the French were desultory in the aftermath of Ligny. Napoleon wasted the morning of 17 June by taking a late breakfast and going to see the previous day's battlefield before organising a pursuit of the two Coalition armies. He took the reserves and marched with Ney in pursuit of the Duke of Wellington's Anglo-allied army, and he gave instructions to Marshal Grouchy to pursue the Prussians wherever they were going and harry them so that they had no time to reorganise.

After their defeat at the Battle of Ligny the Prussians successfully disengaged and withdrew to north west to Wavre where they reorganised. Leaving one corps in Wavre as a blocking rearguard, the three other corps advanced westward to attack the right flank of the French army in front of Waterloo. Both Napoleon and Grouchy assumed that the Prussians were retreating towards Namur and Liège, with a view to occupy the line of the river Meuse, and so during 17 June Grouchy sent the bulk of his cavalry ranging in that direction as far as Perwez. In his despatch to Napoleon written at 22:00 he was still thought that most of the Prussian army was retreating north-east, although by then he realised that two Prussian corps were heading north towards Wavre. In a second dispatch written four hours later he informed Napoleon that he now intended to advance either on Corbais or Wavre. The problem for the French was that by the end of 17 June, most of Grouchy's detachment was now behind the Prussians, on the far side of the Dyle. This meant that they were incapable of preventing the Prussians moving from Wavre towards Waterloo and too far away themselves to go directly to the aid of Napoleon on 18 June should Wellington turn and fight south of Brussels.

Upon receiving the news of Blücher's defeat, Wellington organised the retreat of the Anglo-allied army to a place he had identified a year before as the best place in front of Brussels for him to be able to employ his reverse slope tactics when fighting a major battle: Mont-Saint-Jean escarpment close to the village of Waterloo.

Aided by thunderstorms and torrential rain, Wellington's army successfully extricated itself from Quatre Bras and passed through the defile of Genappe. The infantry marched ahead and were screened by a large cavalry rearguard. The French harried Wellington's army, and there was a cavalry action at Genappe. However the French were unable to inflict any substantial casualties before night fell and Wellington's men were ensconced in bivouacs on the plain of Mont-Saint-Jean.

Waterloo (18 June)
It was at Waterloo on 18 June 1815 that the decisive battle of the campaign took place. The start of the battle was delayed for several hours as Napoleon waited until the ground had dried from the previous night's rain. By late afternoon the French army had not succeeded in driving Wellington's forces from the rise on which they stood. Once the Prussians arrived, attacking the French right flank in ever increasing numbers, Napoleon's key strategy of keeping the Seventh Coalition armies divided had failed and his army was driven from the field in confusion, by a combined coalition general advance.

On the morning of 18 June 1815 Napoleon sent orders to Marshal Grouchy, commander of the right wing of the Army of the North, to harass the Prussians to stop them reforming. These orders arrived at around 06:00 and his corps began to move out at 08:00; by 12:00 the cannon from the Battle of Waterloo could be heard. Grouchy's corps commanders, especially Gérard, advised that they should "march to the sound of the guns". As this was contrary to Napoleon's orders ("you will be the sword against the Prussians' back driving them through Wavre and join me here") Grouchy decided not to take the advice. It became apparent that neither Napoleon nor Marshal Grouchy understood that the Prussian army was no longer either routed or disorganised. Any thoughts of joining Napoleon were dashed when a second order repeating the same instructions arrived around 16:00.

Wavre (18–19 June)
Following Napoleon's orders Grouchy attacked the Prussian III Corps under the command of General Johann von Thielmann near the village of Wavre. Grouchy believed that he was engaging the rearguard of a still-retreating Prussian force. However, only one Corps remained; the other three Prussian Corps (I, II and the still fresh IV) had regrouped after their defeat at Ligny and were marching toward Waterloo.

The next morning the Battle of Wavre ended in a hollow French victory. Grouchy's wing of the Army of the North withdrew in good order and other elements of the French army were able to reassemble around it. However, the army was not strong enough to resist the combined coalition forces, so it retreated toward Paris.

First week (18 – 24 June)
After the combined victory at Waterloo by the Anglo-allies under the command of the Duke of Wellington and the Prussians under the command of Prince Blücher, it was agreed by the two commanders, on the field of Waterloo, that the Prussian army, not having been so much crippled and exhausted by the battle, should undertake the further pursuit, and proceed by Charleroi towards Avesnes and Laon; whilst the Anglo-allied army, after remaining during the night on the field, should advance by Nivelles and Binche towards Péronne.

The 4,000 Prussian cavalry, that kept up an energetic pursuit during the night of 18 June, under the guidance of Marshal Gneisenau, helped to render the victory at Waterloo still more complete and decisive; and effectually deprived the French of every opportunity of recovering on the Belgian side of the frontier and to abandon most of their cannons.

A defeated army usually covers its retreat by a rear guard, but here there was nothing of the kind. The rearmost of the fugitives having reached the river Sambre, at Charleroi, Marchienne-au-Pont, and Châtelet, by daybreak of 19 June 1815, indulged themselves with the hope that they might then enjoy a short rest from the fatigues which the relentless pursuit by the Prussians had entailed upon them during the night; but their fancied security was quickly disturbed by the appearance of a few Prussian cavalry, judiciously thrown forward towards the Sambre from the Advanced Guard at Gosselies. They resumed their flight, taking the direction of Beaumont and Philippeville.

From Charleroi, Napoleon proceeded to Philippeville; whence he hoped to be able to communicate more readily with Marshal Grouchy (who was commanding the detached and still intact right wing of the Army of the North). He tarried for four hours expediting orders to generals Rapp, Lecourbe, and Lamarque, to advance with their respective corps by forced marches to Paris (for their corps locations see the military mobilisation during the Hundred Days): and also to the commandants of fortresses, to defend themselves to the last extremity. He desired Marshal Soult to collect together all the troops that might arrive at this point, and conduct them to Laon; for which place he himself started with post horses, at 14:00.

The French army, under Soult, retreated on Laon in great confusion. The troops commanded by Grouchy, which had reached Dinant, retired in better order; but they were cut off from the wreck of the main army, and also from the direct road to Paris. Grouchy, therefore, was compelled to take the road to Rethel whence he proceeded to Rheims; and by forced marches he endeavoured to force a junction with Soult, and thus reach the capital before the Coalition armies.

In the meantime, Wellington proceeded rapidly into the heart of France; but as there was no enemy in the field to oppose his progress, the fortresses alone demanded his attention. On 20 June 1815 an order of the day was issued to the British army before they entered France. It placed the officers and men in his army under military order to treat the ordinary French population as if they were members of a Coalition nation. This by and large Wellington's army did paying for food and lodgings. This was in sharp contrast to the Prussian army, whose soldiers treated the French as enemies, plundering the populace and wantonly destroying property during their advance.

From Beaumont, the Prussians advanced to Avesnes, which surrendered to them on 21 June. The French at first seemed determined to defend the place to the last extremity, and made considerable resistance; but a magazine having blown up, by which 400 men were killed, the rest of the garrison, which consisted chiefly of national-guards, and amounting to 439 men, surrendered at discretion. On capture of the town the Prussian soldiers treated it as a captured enemy town (rather than one liberated for their ally King Louis XVIII), and on entering the town, the greatest excesses were committed by the Prussian soldiery, which instead of being restrained was encouraged by their officers.

On his arrival at Malplaquet—the scene of one of the Duke of Marlborough's victories—Wellington issued the Malplaquet proclamation to the French people on the night 21/22 June 1815, in which he referred to the order of the day addressed to his army, as containing an explanation of the principles by which his army would be guided.

Napoleon arrived in Paris, three days after Waterloo (21 June), still clinging to the hope of concerted national resistance; but the temper of the chambers and of the public generally forbade any such attempt. Napoleon and his brother Lucien Bonaparte were almost alone in believing that, by dissolving the chambers and declaring Napoleon dictator, they could save France from the armies of the powers now converging on Paris. Even Davout, minister of war, advised Napoleon that the destinies of France rested solely with the chambers. Clearly, it was time to safeguard what remained; and that could best be done under Talleyrand's shield of legitimacy.

Napoleon himself at last recognised the truth. When Lucien pressed him to "dare", he replied, "Alas, I have dared only too much already". On 22 June 1815 he abdicated in favour of his son, Napoléon Francis Joseph Charles Bonaparte, well knowing that it was a formality, as his four-year-old son was in Austria.

With the abdication of Napoleon (22 June) the French Provisional Government led by Fouché appointed Marshal Davout, Napoleon's minister of war, as General in Chief of the army, and opened peace negotiations with the two Coalition commanders.

On 24 June, Sir Charles Colville took the town of Cambrai by escalade, the governor retiring into the citadel, which he afterwards surrendered on 26 June, when it was given up to the order of Louis XVIII. Saint-Quentin was abandoned by the French, and was occupied by Blücher: and, on the evening of 24 June, the castle of Guise surrendered to the Prussian army. The Coalition armies, at least 140,000 strong, continued to advance.

Second week (25 June – 1 July)
On 25 June Napoleon received from Fouché, the president of the newly appointed Provisional Government (and Napoleon's former police chief), an intimation that he must leave Paris. He retired to Malmaison, the former home of Joséphine, where she had died shortly after his first abdication.

On 27 June, Le Quesnoy surrendered to Wellington's army. The garrison, which amounted to 2,800 men, chiefly national-guards, obtained liberty to retire to their homes.

On 26 June, Péronne was taken by the British troops. The first brigade of guards, under Major-general Maitland, took by storm the horn-work which covers the suburbs on the left of the Somme, and the place immediately surrendered, upon the garrison obtaining leave to retire to their homes.

On 28 June, the Prussians, under Blücher, were at Crépy, Senlis, and La Ferté-Milon; and, on 29 June, their advanced guards were at Saint-Denis and Gonesse. The resistance experienced by the British army at Cambrai and Péronne, detained them one day behind the Prussian army; but forced marches enabled them to overtake it in the neighbourhood of Paris.

In the meantime, Soult was displaced from the chief command of the army, which was conferred on Marshal Grouchy. The reason of this remarkable step, according to Soult, was because the Provisional Government suspected his fidelity. This was very likely the true reason; or they could scarcely at this moment have dismissed a man clearly superior to his successor, in point of abilities.

The rapid advance of the Coalition armies caused Grouchy to redouble his speed to reach Paris before them. This he effected, after considerable loss, particularly on the 28th, at the Battle of Villers-Cotterêts where he fell in with the left wing of the Prussian army, and afterwards with the division under General Bülow, which drove him across the river Marne, with the loss of six pieces of cannon and 1,500 prisoners. Grouchy fairly acknowledged, that his troops would not fight, and that numbers deserted. In fact, though the French army was daily receiving reinforcements from the towns and depots in its route, and also from the interior, the desertion from it was so great that its number was little if any thing at all augmented.

With the remainder, however, Grouchy succeeded in retreating to Paris, where he joined the wreck of the main army, the whole consisting of about 40 or 50,000 troops of the line, the wretched remains (including also all reinforcements) of 150,000 men, which fought at Quatre Bras and Waterloo. To these, however, were to be added the national-guards, a new levy called les Tirailleurs de la Garde, and the Federés. According to Bonaparte's portfolio, found at Waterloo, these latter amounted to 14,000 men. Altogether, these forces were at least 40,000 more, if not a greater number. Paris was, therefore, still formidable, and capable of much resistance.

On 29 June the near approach of the Prussians, who had orders to seize Napoleon, dead or alive, caused him to retire westwards toward Rochefort, whence he hoped to reach the United States. The presence of blockading Royal Navy warships under Vice Admiral Henry Hotham with orders to prevent his escape forestalled this plan.

Meanwhile, Wellington continued his operations with unabating activity. As the armies approached the capital, Fouché, president of the Provisional Government, wrote a letter to the British commander, asking him to halt the progress of war.

On 30 June Blücher made a movement which proved decisive of the fate of Paris. Blücher having taken the village of Aubervilliers, made a movement to his right, and crossing the Seine at Lesquielles-Saint-Germain, downstream of the capital, threw his whole force, (apart from a skeleton force holding the Coalition line north of the city) upon the west-south side of the city, where no preparations had been made to receive an enemy.

On 1 July Wellington's army arrived in force and occupied the Coalition lines north of Paris. South of Paris, at the Battle of Rocquencourt a combined arms French force of commanded by General Exelmans destroyed a Prussian brigade of hussars under the command of Colonel von Sohr (who was severely wounded and taken prisoner during the skirmish), but this did not prevent the Prussians moving their whole army to the south side.

Third week (2–7 July)
By the morning of 2 July, Blücher had his right at Plessis-Piquet, and his left at Meudon, with his reserves at Versailles. This was a thunderbolt to the French; and it was then that their weakness and the Coalition strength was seen in the most conspicuous point of view; because, at that moment, the armies of Wellington and Blücher were separated, and all the French army, between them, yet the French could not move to prevent their junction (to shorten their lines of communications Wellington threw a bridge over the Seine at Argenteuil, crossed that river close to Paris, and opened the communication with Blücher). After the war Lazare Carnot (Napoleon's Minister of Internal Affairs) blamed Napoleon for not fortifying Paris on the south side, and said he forewarned Napoleon of this danger.

To defend against the Prussian move, the French were obliged to move two corps over the Seine to meet Blücher. The fighting to the south of Paris on 2 July, was obstinate, but the Prussians finally surmounted all difficulties, and succeeded in establishing themselves firmly upon the heights of Meudon and in the village of Issy. The French loss, on this day, was estimated at 3,000 men.

The early next morning (3 July) at around 03:00, General Dominique Vandamme (under Davout's command) was decisively defeated by General Graf von Zieten (under Blücher's command) at the Battle of Issy, forcing the French to retreat into Paris. All further resistance, it was now obvious, would prove unavailing. Paris now lay at the mercy of the Coalition armies. The French high command decided that, providing terms were not too odious, they would capitulate and ask for an immediate armistice.

Delegates from both sides met at Palace of St. Cloud and the result of the delegates' deliberations was the surrender of Paris under the terms of the Convention of St. Cloud. As agreed in the convention, on 4 July, the French Army, commanded by Marshal Davoust, left Paris and proceeded on its march to the southern side of Loire. On 6 July, the Anglo-allied troops occupied the Barriers of Paris, on the right of the Seine; while the Prussians occupied those upon the left bank. On 7 July, the two Coalition armies entered the centre of Paris. The Chamber of Peers, having received from the Provisional Government a notification of the course of events, terminated its sittings; the Chamber of Representatives protested, but in vain. Their president (Lanjuinais) resigned his chair; and on the following day, the doors were closed, and the approaches guarded by Coalition troops.

Aftermath
On 8 July, the French King, Louis XVIII, made his public entry into Paris, amidst the acclamations of the people, and again occupied the throne.

On 10 July, the wind became favourable for Napoleon to set sail from France. But a British fleet made its appearance and made escape by sea impossible. Unable to remain in France or escape from it, Napoleon surrendered to Captain Frederick Maitland of HMS Bellerophon (1786) early in the morning of 15 July and was transported to England. Napoleon was exiled to the island of Saint Helena where he died as a prisoner-of-war in May 1821.

Some commandants of the French fortresses did not surrender upon the fall of the Provisional Government on 8 July 1815 and continued to hold out until forced to surrender by Commonwealth forces. The last to do so was Fort de Charlemont which capitulated on 8 September (see reduction of the French fortresses in 1815). In November 1815 a formal Peace treaty between France and the Seventh Coalition was signed. The Treaty of Paris (1815) was not as generous to France as the Treaty of Paris (1814) had been. France lost territory, had to pay reparations, and agreed to pay for an army of occupation for not less than five years.

Analysis

It attracted the attention of Wellington's staff, who prompted him to write his only published essay on the campaign (other than his immediate, official after-action reports (such as the "Waterloo dispatch to Lord Bathurst"), his 1842 Memorandum on the Battle of Waterloo.
