Military mobilisation during the Hundred Days

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 (D'Erlon) cantoned between Lille and Valenciennes.
  • II Corps (Reille) cantoned between Valenciennes and Avesnes.
  • III Corps (Vandamme) cantoned around Rocroi.
  • IV Corps (Gerard) cantoned at Metz.
  • VI Corps (Lobau) cantoned at Laon.
  • Cavalry Reserve (Grouchy) cantoned at Guise.
  • Imperial Guard (Mortier) at Paris.
  • The preceding corps were to be formed into L'Armée du Nord (the "Army of the North") and led by Napoleon Bonaparte 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 (Rapp), cantoned near Strassburg.

  • 15th Infantry Division;
  • 16th Infantry Division;
  • 17th Infantry Division;
  • 7th Cavalry Division;
  • National Guard Division;
  • 46 guns;
  • Total 20,000–23,000 men.

  • 5th Chasseurs à Cheval Cavalry Regiment;
  • 24 guns;
  • Total 3,516–7,600 men.

  • Total 3,516–6,800 men
  • Army of the West - Armée de l'Ouest (also known as the Army of the Vendée and the Army of the Loire). Commanded by General Jean Maximilien Lamarque, the army was formed to suppress the Royalist insurrection in the Vendée region of France, which remained loyal to King Louis XVIII during the Hundred Days. The army contained a Young Guard Infantry brigade consisting of the 2nd Tirailleur and 2nd Voltigeur regiments and some line units detached from the other armies as well as gendarmes and volunteers. Its composition in June was:

  • One Un-numbered Infantry Division under General Brayer;
  • One Un-numbered Infantry Division under General Travot;
  • 24 guns;
  • Total 10,000–27,000 men.

    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 (those designated to proceed to Paris) was as follows:

    Wellington's Allied Army (Army of Flanders)

    Cantoned in the southern part of the 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 (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 (under Wellington himself) 25,500, lay around Brussels.
  • Reserve Cavalry (Lord Uxbridge) 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 (it was posted to a fall back position near Braine), but did besiege some of the frontier fortresses in the rear of Wellington's advancing army.

    A Danish contingent known as the Royal Danish Auxiliary Corps commanded by General Prince Frederick of Hessen-Kassel and a Hanseatic contingent (from the free cities of Bremen, Lübeck and Hamburg) later commanded by the British Colonel Sir Neil Campbell, were also on their way to join this army, both however, joined the army in July having missed the conflict.

    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 (he was still in Brazil where he had been in exile during the Peninsular War and had yet to return to Portugal). 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 were a shadow of their former self with much of it being disbanded.

    The Tsar 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 (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 Liege and cantoned around it.
  • 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 Hessen, Grand Duchy of Mecklenburg-Schwerin, Grand Duchy of Mecklenburg-Strelitz, Grand Duchy of Saxe-Weimar-Eisenach, Duchy of Oldenburg (state), Duchy of Saxe-Gotha, Duchy of Anhalt-Bernburg, Duchy of Anhalt-Dessau, Duchy of Anhalt-Kothen, Principality of Schwarzburg-Rudolstadt, Principality of Schwarzburg-Sondershausen, Principality of Waldeck (state), 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 Hessen-Kassel General von Engelhardt (who was in command of the Hessen division) and then by Lieutenant General Karl Georg Albrecht Ernst von Hake. Its composition in June was:

  • Hessen-Kassel Division (Three Hessian Brigades)- General Engelhardt
  • Hessian 1st Brigade (5 battalions) – Major General Prince of Solms-Braunfels
  • Hessian 2nd Brigade (7 battalions) – Major General von Muller
  • Hessian Cavalry Brigade (2 regiments) – Major General von Warburg (Prussian)
  • Hessian Artillery (2 six-pounder batteries) – Najor von Bardeleben (Prussian)
  • Thuringian Brigade - Major General Egloffstein (Weimar)
  • 1st Provisional Infantry Regiment (4 battalions):
  • 2nd Provisional Infantry Regiment (3 battalions)
  • 3rd Provisional Infantry Regiment (5 battalions including the Oldenbug Line Infantry Regiment (2 battalions))
  • Total 25,000

    Russian Army (I Army)

    Field Marshal Michael Andreas Barclay de Tolly commanded the First Russian Army. In June it consisted of the following:

  • III Army Corps - General Dokhturov
  • IV Army Corps - General Raevsky
  • V Army Corps - General Sacken
  • VI Army Corps - General Langeron
  • VII Army Corps - General Sabaneev
  • Reserve Grenadier Corps - General Yermolov
  • II Reserve Cavalry Corps - General Winzingerode
  • Artillery Reserve - Colonel Bogoslavsky
  • Total 200,000

    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 (Hessen-Darmstadt), 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:

    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 Lyons. General Johann Maria Philipp Frimont commanded this army. Its composition in June was:

  • I Corps - Major-General (Feldmarschalleutnant) Paul von Radivojevich
  • II Corps - Major-General (Feldmarschalleutnant) Ferdinand, Graf Bubna von Littitz
  • Reserve Corps - Major-General (Feldmarschalleutnant) Franz Mauroy de Merville
  • Sardinian Corps - General De La Tour
  • Total 50,000

    Austrian Army (Army of Naples)

    This was the smallest of Austria's military contingents. Its targets were Marseilles and Toulon. General Bianchi commanded this army. This was the Austrian army that defeated 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 Louis Cacherano d'Osasco which may have been where the other part of this misunderstanding had arisen. Its composition in June was:

  • I Corps - General Neipperg
  • II Corps - General Mohr
  • Reserve Corps - General Nugent
  • Total 23,000

    Anglo-Sicilian Army

    This was Great Britain's smaller military contingent. It was composed of Anglo-Sicilian troops under General Sir Hudson Lowe transported and supported by the Mediterranean Fleet of Lord Viscount Exmouth. Its targets were Marseilles and Toulon.

    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 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, (See the section Portuguese contingent below), however both Chandler and Barbero state that the Portuguese did send a contingent.

    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 (VIII Corps) - 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 (from the free cities of Bremen, Lübeck and Hamburg) 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 (he was still in Brazil where he had been in exile during the Peninsular War and had yet to return to Portugal). 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 were a shadow of their former 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.
