Hundred Days order of battle

During the Hundred Days of 1815, both the Coalition nations and the First French Empire of Napoleon Bonaparte mobilised for war. This article describes the deployment of forces in early June 1815 just before the start of the Waterloo Campaign and the minor campaigns of 1815.

French

Upon assumption of the throne, Napoleon found that he was left with little by the Bourbons and that the state of the Army was 56,000 troops 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 up but not yet ready for deployment.

Waterloo Campaign

By the end of May, Napoleon had deployed his forces as follows:

I Corps cantoned between Lille and Valenciennes.
II Corps cantoned between Valenciennes and Avesnes.
III Corps cantoned around Rocroi.
IV Corps cantoned at Metz.
VI Corps cantoned at Laon.
Cavalry Reserve cantoned at Guise.
Imperial Guard at Paris.

The preceding corps were to be formed into L'Armée du Nord, led by Napoleon Bonaparte and would participate in the Waterloo Campaign.

Armies of observation

For the defence of France, Bonaparte deployed his remaining forces within France observing France's enemies, foreign and domestic, intending to delay the former and suppress the latter. By June, they were organised as follows:
V Corps – Armée du Rhin, cantoned near Strassburg.

Seventh Coalition

The Seventh Coalition armies formed to invade France were:

Overview

The forces at the disposal of the Seventh Coalition for an invasion of France amounted to the better part of a million men. According to the returns laid out in secret sittings at the Congress of Vienna the military resources of the European states that joined the coalition, the number of troops which they could field for active operations—without unduly diminishing the garrison and other services in their respective interiors—amounted to 986,000 men. The size of the principal invasion armies was as follows:

Waterloo Campaign

Wellington's Allied Army (Army of Flanders)

Cantoned in the southern part of the United Kingdom of the Netherlands, in what is now Belgium, Field Marshal Arthur Wellesley, 1st Duke of Wellington commanded a coalition army, made up of troops from the duchies of Brunswick, and Nassau and the kingdoms of Hanover, the Netherlands and the United Kingdom.
In June 1815 Wellington's army of 93,000 with headquarters at Brussels was cantoned:

I Corps, 30,200, headquarters Braine-le-Comte, disposed in the area Enghien–Genappe–Mons.
II Corps, 27,300, headquarters Ath, distributed in the area Ath-Oudenarde–Ghent.
Reserve 25,500, lay around Brussels.
Reserve Cavalry 9,900, in the valley of the Dendre river, between Geraardsbergen and Ninove.
Dutch light cavalry observed the frontier into the west of Leuze and Binche

The Netherlands Corps, commanded by Prince Frederick of the Netherlands did not take part in early actions of the Waterloo Campaign, but did besiege some of the frontier fortresses in the rear of Wellington's advancing army.
Alexander I of Russia offered Wellington his II Army Corps under general Wurttemberg, but Wellington was far from keen on accepting this contingent.

Prussian Army (Army of the Lower Rhine)

This army was composed entirely of Prussians from the provinces of the Kingdom of Prussia, old and recently acquired alike. Field Marshal Gebhard Leberecht von Blücher commanded this army with General August Neidhardt von Gneisenau as his chief of staff and second in command.
Blücher's Prussian army of 116,000 men, with headquarters at Namur, was distributed as follows:

I Corps, 30,800, cantoned along the Sambre, headquarters Charleroi, and covering the area Fontaine-l'Évêque–Fleurus–Moustier.
II Corps, 31,000, headquarters at Namur, lay in the area Namur-Hannut–Huy.
III Corps, 23,900, in the bend of the river Meuse, headquarters Ciney, and disposed in the area Dinant–Huy–Ciney.
IV Corps, 30,300, with headquarters at Liège and cantoned around it.

Minor campaigns

German Corps (North German Federal Army)

This army was part of the Prussian army above, but was to act independently much further south. It was composed of contingents from the following nations of the German Confederation: Electorate of Hesse, Grand Duchy of Mecklenburg-Schwerin, Grand Duchy of Mecklenburg-Strelitz, Grand Duchy of Saxe-Weimar-Eisenach, Grand Duchy of Oldenburg, Duchy of Saxe-Gotha-Altenburg, Duchy of Anhalt-Bernburg, Duchy of Anhalt-Dessau, Duchy of Anhalt-Kothen, Principality of Schwarzburg-Rudolstadt, Principality of Schwarzburg-Sondershausen, Principality of Waldeck and Pyrmont, Principality of Lippe and the Principality of Schaumburg-Lippe.
Fearing that Napoleon was going to strike him first, Blücher ordered this army to march north to join the rest of his own army. The Prussian General Friedrich Graf Kleist von Nollendorf initially commanded this army before he fell ill on 18 June and was replaced temperately by the Hesse-Kassel General von Engelhardt and then by Lieutenant General Karl Georg Albrecht Ernst von Hake. Its composition in June was:

Hessen-Kassel Division - General Engelhardt
* Hessian 1st Brigade – Major General Prince of Solms-Braunfels

Austro-German Army (Army of the Upper Rhine)

The Austrian military contingent was divided into three armies. This was the largest of these armies, commanded by Field Marshal Karl Philipp, Prince of Schwarzenberg. Its target was Paris. This Austrian contingent was joined by those of the following nations of the German Confederation: Kingdom of Bavaria, Kingdom of Württemberg, Grand Duchy of Baden, Grand Duchy of Hesse, Free City of Frankfurt, Principality of Reuss Elder Line and the Principality of Reuss Junior Line. Besides these there were contingents of Fulda and Isenburg. These were recruited by the Austrians from German territories that were in the process of losing their independence by being annexed to other countries at the Congress of Vienna. Finally, these were joined by the contingents of the Kingdom of Saxony, Duchy of Saxe-Coburg-Saalfeld, Duchy of Saxe-Meiningen and the Duchy of Saxe-Hildburghausen. Its composition in June was:

Corps	Commander	Men	Battalions	Squadrons	Batteries

Totals		264,492	246	844	66

Swiss Army

This army was composed entirely of Swiss. The Swiss General Niklaus Franz von Bachmann commanded this army. This force was to observe any French forces that operated near its borders. Its composition in July was:

I Division – Colonel von Gady
II Division – Colonel Fuessly
III Division – Colonel d'Affry
Reserve Division – Colonel-Quartermaster Finsler

Total 37,000

Austro-Sardinian Army (Army of Upper Italy)

This was the second largest of Austria's contingents. Its target was Lyon. General Johann Maria Philipp Frimont commanded this army. Its composition in June was:

I Corps – Major-General Paul von Radivojevich
II Corps – Major-General Ferdinand, Graf Bubna von Littitz
Reserve Corps – Major-General Franz Mauroy de Merville
Sardinian Corps – Lieutenant-General Count Latour

Total 50,000

Austrian Army (Army of Naples)

This was the smallest of Austria's military contingents. Its targets were Marseille and Toulon. General Frederick Bianchi commanded this army. This was the Austrian army that defeated Joachim Murat's army in the Neapolitan War. It was not composed of Neapolitans as the army's name may suggest and as one author supposed. There was however a Sardinian force in this area forming the garrison of Nice under Giovanni Pietro Luigi Cacherano d'Osasco which may have been where the other part of this misunderstanding had arisen. Its composition in June was:

I Corps – General Adam Albert von Neipperg
II Corps – General
Reserve Corps – General Laval Nugent von Westmeath

Total 23,000

British Mediterranean contingent

This was Great Britain's smaller military expedition. It was composed of British troops from the garrison of Genoa under General Sir Hudson Lowe transported and supported by the Mediterranean Fleet of Lord Exmouth to Marseille to aid a French Royalist uprising. The British landed about 4,000 men in Marseille, made up of soldiers, marines and sailors.

Other mobilisations

Spanish armies

It was planned that a Spanish army was to invade France via Perpignan and Toulouse. General Francisco Javier Castanos, 1st Duke of Bailen commanded this army.
It was planned that a second Spanish army was to invade France over the river Bidassoa and into France via Bayonne and Bordeaux. General Henry Joseph O'Donnell, Count of La Bisbal commanded this army.
Both Wellington's Despatches and his Supplementary Despatches show that neither of the Spanish armies contained any Portuguese contingents nor were they likely too,, however both Chandler and Barbero state that the Portuguese did send a contingent.

Netherlands reserve army

In order to support the Netherlands field army, plans had been made on 24 May to raise a reserve army. It wasn’t until 19 July until the organisation of the army was laid out: it was to consist of 30 infantry battalions, 18 cavalry squadrons, and four artillery batteries. The infantry was organised from the newly acquired Swiss regiments and newly raised Belgian Militia battalions; the cavalry from the reserves of all nine cavalry regiments, including the colonial hussars and Belgian Militia Carabiniers. By then, the Coalition armies had already set up camp around Paris. The army, existing largely only on paper, was disbanded after three months. Only the 43rd National Militia Infantry Battalion, part of the 4th Infantry Brigade, was deployed in the observation of Bouillon.
Commander: Lieutenant-General baron Ralph Dundas Tindal, Quartermaster / Adjudant-general: Major General D.L. Vermaesen:

1st Infantry Division, Lieutenant-general Baron Tindal
2nd Infantry Division, Lieutenant general Gijsbertus Martinus Cort Heyligers
Cavalry Division, Lieutenant general Baron Evers

Prussian Reserve Army

Besides the four Army Corps that fought in the Waterloo Campaign listed above that Blücher took with him into the Kingdom of the Netherlands, Prussia also had a reserve army stationed at home in order to defend its borders.
This consisted of:

V Army Corps – Commanded by General Ludwig Yorck von Wartenburg
VI Army Corps – Commanded by General Bogislav Friedrich Emanuel von Tauentzien
Royal Guard – Commanded by General Charles II, Grand Duke of Mecklenburg-Strelitz

Royal Danish Auxiliary Corps and Hanseatic Contingent

A Danish contingent known as the Royal Danish Auxiliary Corps commanded by General Prince Frederick of Hessen-Kassel and a Hanseatic contingent commanded by the British Colonel Sir Neil Campbell, were also on their way to join Wellington's army, both however, joined the army in July having missed the conflict.

Portuguese contingent

Wellington had very much hoped to obtain a Portuguese contingent of 12–14,000 men that might be boarded on ships and sent to this army. However, this contingent never materialised, as the Portuguese government were extremely uncooperative. They explained that they did not have the authority to send the Prince Regent of Portugal's forces to war without his consent. They explained this even though they themselves had signed the Treaty of 15 March without his consent. Besides this, the state of the Portuguese Army in 1815 left much to be desired and it was a shadow of its former self with much of it being disbanded.

Russian 2nd (Reserve) Army

The Second Russian Army was behind the First Russian Army to support it if required.

Imperial Guard Corps
I Army Corps
II Army Corps, commanded by General Wurttemberg
I Grenadier Division
I Reserve Cavalry Corps

Russian support for Wellington

The Tsar of Russia offered Wellington the II Army Corps under General Wurttemberg from his Reserve Army, but Wellington was far from keen on accepting this contingent.
