Battle of Waterloo. The battle on 18 June 1815 ended Napoleon Bonaparte's rule and the Hundred Days by delivering a decisive defeat to the First French Empire at Waterloo near Brussels. It pitted Napoleon against an Anglo-Allied army under the Duke of Wellington and a Prussian army under Gebhard Leberecht von Blücher, concluding a campaign that reshaped post-Napoleonic Europe and led directly into the Second Treaty-driven settlement dominated by the Congress of Vienna principals.
Background
After escaping exile on Elba, Napoleon returned to France in March 1815, initiating the period known as the Hundred Days and prompting the Seventh Coalition formed by powers including the United Kingdom of Great Britain and Ireland, the Kingdom of Prussia, the Austrian Empire, the Russian Empire, and the Kingdom of the Netherlands. The Coalition mobilized forces under commanders such as the Duke of Wellington and Gebhard Leberecht von Blücher to oppose Napoleon's bid to restore the First French Empire. Napoleon aimed to neutralize Coalition armies in the Low Countries before they could concentrate, anticipating that a swift victory would compel favourable terms from the negotiators at the Congress of Vienna and alter the diplomatic balance among states like Prussia, Austria, and Russia.
Opposing forces
Napoleon's main field army assembled veterans from campaigns against the Austrian Empire, the Russian Empire, and the Kingdom of Spain, commanded by marshals and generals such as Michel Ney, Emmanuel de Grouchy, Nicolas-Charles Oudinot, and Jean-Baptiste Drouet, Comte d'Erlon. The Anglo-Allied army under the Duke of Wellington incorporated units from the Kingdom of the Netherlands, Kingdom of Hanover, and other German contingents, with divisional commanders including Thomas Picton, William Ponsonby, and Frederick William, Duke of Brunswick-Wolfenbüttel. The Prussian army under Gebhard Leberecht von Blücher featured corps led by Blücher's subordinates such as August Neidhardt von Gneisenau and Hans Ernst Karl, Graf von Zieten, providing crucial mobility and strategic depth. Artillery and cavalry quality, unit experience from earlier engagements like the Battle of Ligny and the Battle of Quatre Bras, and supply lines influenced operational effectiveness on both sides.
The campaign and movements
Napoleon launched an offensive into the United Kingdom of the Netherlands aiming to split and defeat the Anglo-Allied and Prussian armies before they could unite. On 16 June 1815 French forces won at the Battle of Ligny against the Prussians while Marshal Michel Ney engaged the Anglo-Allied force at Battle of Quatre Bras, delaying Wellington but failing to force a decisive separation. After Ligny the Prussians withdrew in good order toward Wavre under Gebhard Leberecht von Blücher, maintaining lines of communication that allowed a rapid march to support Wellington. Napoleon's operational choices, including the dispatch of Emmanuel de Grouchy with a large detachment to pursue Prussian forces, proved controversial because it limited French capacity to concentrate at Waterloo. Wellington selected a defensive position along the ridge south of Waterloo anchored on strong points like the farms of Hougoumont and La Haye Sainte.
The battle
Fought on a rain-softened battlefield, the action began with a delayed French attack and heavy artillery exchanges. Marshal Michel Ney led cavalry charges against Wellington's infantry squares, while French infantry assaults under commanders such as Jean-Baptiste Drouet, Comte d'Erlon targeted allied strongpoints. The defence of the chateau and farm of Hougoumont and the defence of La Haye Sainte were focal points that absorbed French efforts and casualties. Late in the day, the Prussian main body under Gebhard Leberecht von Blücher began arriving on Napoleon's right flank, engaging Marshal Grouchy's forces near Wavre and advancing toward the ridge. In the final phase, Napoleon committed the Imperial Guard in a decisive assault; their repulse by allied infantry and cavalry, combined with Prussian pressure, precipitated the collapse of French morale and the rout of Napoleon's army.
Aftermath and casualties
The defeat forced Napoleon to abdicate for the second time on 22 June 1815 and seek exile on Saint Helena under British supervision, overseen in the broader settlement by diplomats from the Congress of Vienna including figures linked to the Holy Alliance. Casualties were heavy: French losses are estimated around 25,000–30,000 killed, wounded, or captured, while Coalition casualties (British, Netherland, Hanoverian, Brunswick, and Prussian contingents) numbered roughly 22,000. Prisoners, deserters, and the loss of artillery and standards degraded the First French Empire's capacity to continue major continental operations. The battlefield aftermath involved matters handled by local authorities of the United Kingdom of the Netherlands and international staff officers coordinating repatriation and burial.
Legacy and historical assessment
The battle decisively ended Napoleonic attempts at European hegemony and reinforced the diplomatic order established by the Congress of Vienna, affecting relations among the United Kingdom, Prussia, Austria, and Russia throughout the 19th century. Military historians examine Waterloo for lessons in command, coalition warfare, logistics, and the use of infantry squares versus cavalry and artillery, comparing it to engagements like the Battle of Austerlitz and the Battle of Borodino. Cultural memory of the battle influenced literature, art, monuments such as the Lion's Mound near Waterloo, and commemorations in Britain, Prussia, and the Netherlands; figures from the campaign, including Napoleon, the Duke of Wellington, and Gebhard Leberecht von Blücher, remain central in studies of the Napoleonic era. Contemporary reassessments debate Napoleon's operational choices, Grouchy's pursuit, and Wellington's defensive tactics, situating Waterloo as a pivotal event in European state-system consolidation and the age of the great-power concert.
