The Battle of Waterloo was fought on Sunday 18 June 1815, near Waterloo, marking the end of the Napoleonic Wars. A French army under the command of Napoleon was defeated by two armies of the Seventh Coalition. One of these was a British-led force with units from the United Kingdom, the Netherlands, Hanover, Brunswick, and Nassau, under the command of the Duke of Wellington. The other comprised three corps of the Prussian army under Field Marshal Blücher; a fourth corps of this army fought at the Battle of Wavre on the same day. The battle was known contemporarily as the Battle of Mont Saint-Jean in France and La Belle Alliance in Prussia.
The British Army is the principal land warfare force of the United Kingdom, British Overseas Territories and Crown Dependencies, a part of the British Armed Forces along with the Naval Service and the Royal Air Force. As of 1 January 2024, the British Army comprises 75,166 regular full-time personnel, 4,062 Gurkhas, 26,244 volunteer reserve personnel and 4,557 "other personnel", for a total of 110,029.
The Napoleonic Wars (1803–1815) were a series of conflicts fought between the First French Empire under Napoleon Bonaparte (1804–1815) and a fluctuating array of European coalitions. The wars originated in political forces arising from the French Revolution (1789–1799) and from the French Revolutionary Wars (1792–1802) and produced a period of French domination over Continental Europe. The wars are categorised as seven conflicts, five named after the coalitions that fought Napoleon, plus two named for their respective theatres: the War of the Third Coalition, War of the Fourth Coalition, War of the Fifth Coalition, War of the Sixth Coalition, War of the Seventh Coalition, the Peninsular War, and the French invasion of Russia.
The Battle of Austerlitz, also known as the Battle of the Three Emperors, was one of the most important military engagements of the Napoleonic Wars. The battle occurred near the town of Austerlitz in the Austrian Empire. Around 158,000 troops were involved, of which around 24,000 were killed or wounded. The battle is often cited by military historians as one of Napoleon's tactical masterpieces, in the same league as other historic engagements like Cannae or Gaugamela. The military victory of Napoleon's Grande Armée at Austerlitz brought the War of the Third Coalition to an end, with the Peace of Pressburg signed by the French and Austrians later in the month. These achievements did not establish a lasting peace on the continent. Austerlitz had driven neither Russia nor Britain, whose armies protected Sicily from a French invasion, to settle. Prussian resistance to the growing power of French military invasions in Central Europe led to the War of the Fourth Coalition in 1806.
The United Kingdom of Great Britain and Ireland was a sovereign state in Northwestern Europe that was established by the union in 1801 of the Kingdom of Great Britain and the Kingdom of Ireland. The establishment of the Irish Free State in 1922 led to the remainder later being renamed the United Kingdom of Great Britain and Northern Ireland in 1927.
The Battle of Friedland was a major engagement of the Napoleonic Wars between the armies of the French Empire commanded by Napoleon I and the armies of the Russian Empire led by General Levin August von Bennigsen. Napoleon and the French obtained a decisive victory that routed much of the Russian army, which retreated chaotically over the Alle River by the end of the fighting. The battlefield is located in modern-day Kaliningrad Oblast, near the town of Pravdinsk, Russia.
The Kingdom of Great Britain was a sovereign state in Western Europe from 1707 to the end of 1800. The state was created by the 1706 Treaty of Union and ratified by the Acts of Union 1707, which united the kingdoms of England and Scotland to form a single kingdom encompassing the whole island of Great Britain and its outlying islands, with the exception of the Isle of Man and the Channel Islands. The unitary state was governed by a single parliament at the Palace of Westminster, but distinct legal systems—English law and Scots law—remained in use.
The Hundred Days, also known as the War of the Seventh Coalition, marked the period between Napoleon's return from eleven months of exile on the island of Elba to Paris on 20 March 1815 and the second restoration of King Louis XVIII on 8 July 1815. This period saw the War of the Seventh Coalition, and includes the Waterloo Campaign and the Neapolitan War as well as several other minor campaigns. The phrase les Cent Jours was first used by the prefect of Paris, Gaspard, comte de Chabrol, in his speech welcoming the king back to Paris on 8 July.
The French Revolutionary Wars were a series of sweeping military conflicts resulting from the French Revolution that lasted from 1792 until 1802. They pitted France against Great Britain, Austria, Prussia, Russia, and several other countries. The wars are divided into two periods: the War of the First Coalition (1792–1797) and the War of the Second Coalition (1798–1802). Initially confined to Europe, the fighting gradually assumed a global dimension. After a decade of constant warfare and aggressive diplomacy, France had conquered territories in the Italian Peninsula, the Low Countries, and the Rhineland due to its very large and powerful military, which had been totally mobilized for war against most of Europe with mass conscription of the vast French population. French success in these conflicts ensured military occupation and the spread of revolutionary principles over much of Europe.
In the War of the Sixth Coalition, sometimes known in Germany as the Wars of Liberation, a coalition of Austria, Prussia, Russia, Spain, Great Britain, Portugal, Sweden, Sardinia, and a number of German States defeated France and drove Napoleon into exile on Elba. After the disastrous French invasion of Russia of 1812 in which they had been forced to support France, Prussia and Austria joined Russia, the United Kingdom, Sweden, and Portugal, and the rebels in Spain who were already at war with France.
Yeomanry is a designation used by a number of units and sub-units in the British Army Reserve which are descended from volunteer cavalry regiments that now serve in a variety of different roles.
By 1799, the French Revolutionary Wars had resumed after a period of relative peace in 1798. The Second Coalition had organized against France, with Great Britain allying with Russia, Austria, the Ottoman Empire, and several of the German and Italian states. While Napoleon's army was still embroiled in Egypt, the allies prepared campaigns in Italy, Switzerland, and the Netherlands.
The Napoleonic Wars continued from 1799 with the French fighting the forces of the Second Coalition. Napoleon Bonaparte had returned from Egypt and taken control of the French government, marking the end of the French Revolution. He prepared a new campaign, sending Moreau to the Rhine frontier and personally going to take command in the Alps, where French forces had been driven almost out of Italy in 1799.
The Waterloo campaign 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 Cardwell Reforms were a series of reforms of the British Army undertaken by Secretary of State for War Edward Cardwell between 1868 and 1874 with the support of Liberal prime minister William Ewart Gladstone. Gladstone paid little attention to military affairs but he was keen on efficiency. In 1870, he pushed through Parliament major changes in Army organisation. The German Empire's stunning triumph over the Second French Empire in the Franco-Prussian War proved that the Prussian system of professional soldiers with up-to-date weapons was far superior to the traditional system of gentlemen-soldiers that Britain used.
The Special Reserve was established on 1 April 1908 with the function of maintaining a reservoir of manpower for the British Army and training replacement drafts in times of war. Its formation was part of the military reforms implemented by Richard Haldane, the Secretary of State for War, which also created the Territorial Force. Haldane originally intended that the Militia would provide the reserve, but opposition from its representatives forced him to abolish it and create the Special Reserve instead. Only 60 per cent of the Militia transferred into the new reserve, and it was consistently under strength, particularly in officers. Reservists enlisted for a six-year term of service, and had to undergo six months of basic training on recruitment and three to four weeks training annually.
In the United Kingdom, military conscription has existed for two periods in modern times. The first was from 1916 to 1920, and the second from 1939 to 1960. The last conscription term ended in 1963 although many soldiers chose to continue in the service beyond 1963.
The British Militia was the principal military reserve force of the United Kingdom of Great Britain and Ireland. Militia units were repeatedly raised in Great Britain during the Victorian and Edwardian eras for internal security duties and to defend against external invasions. The British Militia was transformed into the Special Reserve under the Territorial and Reserve Forces Act 1907, which integrated all militia formations into the British Army.
The British Militia was the principal military reserve force of the Kingdom of Great Britain. Militia units were repeatedly raised in Great Britain during the Georgian era for internal security duties and to defend against external invasions. The Militia Act 1757, passed by the Parliament of Great Britain after the outbreak of the Seven Years' War, led to the rapid expansion of the British Militia in order to defend from potential French invasions. In the Kingdom of Ireland, a client state of Great Britain, the equivalent force was the Irish Militia, which saw heavy service in the Irish Rebellion of 1798 alongside British militia units. The existence of militia units in Great Britain and Ireland played an important role in freeing regular troops from the British and Irish establishments for overseas service.
The Regular Reserve is the component of the military reserve of the British Armed Forces whose members have formerly served in the "Regular" forces. The Regular Reserve largely consists of ex-Regular personnel who retain a statutory liability for service and are liable to be recalled for active military duty "in case of imminent national danger or great emergency". It also consists of a smaller number of ex-Regulars who serve under a fixed-term reserve contract and are liable for reporting, training and deploying on operations.
