After a day of brutal fighting-cavalry charges, infantry squares holding firm, Prussian reinforcements arriving at the decisive moment-the French collapsed. Napoleon's comeback lasted exactly 100 days. His defeat ended roughly two decades of Napoleonic and Revolutionary warfare spanning from the 1790s. and forced a redrawing of the political map. ## Summary Napoleon had escaped Elba in March 1815 and retaken France without firing a shot, forcing King Louis XVIII to flee. The European powers-Britain, Prussia, Austria, and Russia-immediately mobilized to stop him. By mid-June, British commander the Duke of Wellington and Prussian commander Gebhard Blücher had positioned their armies in southern Belgium, waiting. On June 18, Napoleon attacked Wellington's 67,000-strong force near the village of Waterloo. The French commander, convinced Blücher's Prussians were still a day away, pressed for a quick victory. His cavalry charged repeatedly against British infantry squares-disciplined formations that held firm. The fighting lasted all day, with neither side breaking through. Around 4 p.m., Prussian forces under General Johann von Zieten began arriving on Napoleon's right flank, exactly as Wellington had hoped. Napoleon threw his elite Imperial Guard into a final assault around 7 p.m. These veteran troops, considered unbeatable, were repulsed by British infantry and cavalry under Sir John Colborne. As darkness fell and Prussian reinforcements continued pouring in, French lines collapsed. What followed was a rout. Soldiers threw down weapons and fled; wagons overturned; thousands were captured or killed. By 8 p.m., Wellington and Blücher met on the battlefield and agreed the day was won. The casualty count was staggering. France lost roughly 25,000 men killed or wounded, plus 8,000 captured. Allied losses-about 22,000 total-were nearly as severe, but replacements were available. More importantly, the Prussians and Dutch kept pursuing Napoleon's army for days afterward, preventing any chance of regrouping. Napoleon abdicated four days later and was subsequently exiled to St. Helena, a remote island in the South Atlantic, in August 1815. The Concert of Europe settled into a new order at the Congress of Vienna, where the major powers carved up the map to prevent any single nation from dominating again. Waterloo didn't just end one man's ambitions-it ended an era of revolutionary warfare and ushered in a century of relative (if unstable) great-power peace. ## Key facts - **Date**: June 18, 1815 - **Location**: Near Waterloo, Walloon Brabant, Belgium - **British and Allied force strength**: ~67,000 troops under the Duke of Wellington - **French force strength**: ~72,000 troops under Napoleon Bonaparte - **Prussian reinforcements**: ~50,000 troops under Gebhard Blücher - **French casualties**: ~25,000 killed or wounded; ~8,000 captured - **Allied casualties**: ~22,000 killed or wounded - **Battle duration**: Approximately 12 hours (dawn to dusk) - **Days until Napoleon's abdication**: 4 days (June 22, 1815) ## Timeline - **1815-03-20** - Napoleon escapes Elba Napoleon lands in southern France and begins marching toward Paris. King Louis XVIII flees without military resistance. The Hundred Days begin. - **1815-04-02** - Allied coalition mobilizes Britain, Prussia, Austria, and Russia declare war on Napoleon and begin concentrating armies. The Duke of Wellington is appointed commander of Anglo-Allied forces in Belgium. - **1815-06-15** - Napoleon crosses into Belgium The French army invades Belgium, hoping to split the British and Prussian forces and defeat them in detail. Wellington and Blücher begin positioning their armies. - **1815-06-16** - Battles of Ligny and Quatre-Bras French forces engage Prussians at Ligny and British at Quatre-Bras. The Prussians are pushed back but not destroyed; Wellington holds his position. Both battles claim thousands of casualties. - **1815-06-18** - Battle of Waterloo Napoleon attacks Wellington's line near Waterloo. Repeated French cavalry charges fail against British infantry squares. Prussian forces arrive on the French right flank in the afternoon. The French Imperial Guard's final assault is repulsed. French army collapses; heavy losses on both sides. - **1815-06-22** - Napoleon abdicates After four days of pursued retreat, Napoleon signs his second abdication at the Élysée Palace in Paris. He is taken into custody by the British. - **1815-08-07** - Napoleon exiled to St. Helena The British ship HMS Northumberland sets sail with Napoleon aboard, bound for the remote island of St. Helena in the South Atlantic, where he will spend the rest of his life. ## Relationships - **caused**: treaty-of-versailles - Waterloo's decisive outcome enabled the Concert of Europe framework and directly led to the Treaty of Versailles (1919) settlement that formalized post-Napoleonic territorial redistribution and great-power consensus. - **anticipated**: monroe-doctrine - Waterloo's destruction of French hegemonic ambitions removed the primary European counterweight to British naval dominance, creating the geopolitical vacuum that enabled the U.S. to assert hemispheric independence through the Monroe Doctrine in 1823. - **caused**: american-civil-war-begins - Timeline of "Battle of Waterloo" references "American Civil War" (2 shared tokens incl. title anchor). - **caused by**: storming-of-bastille - Timeline of "Battle of Waterloo" references "French Revolution Begins (Storming of the Bastille)" (2 shared tokens incl. title anchor). - **caused**: july-revolution-france-1830 - Timeline of "Battle of Waterloo" references "July Revolution in France" (2 shared tokens incl. title anchor). ## Consequences - **1815 - Congress of Vienna reshapes Europe**: The powers convened to prevent any single nation from dominating Europe again. Austria, Prussia, Russia, and Britain agreed to the Concert of Europe, a system of collective security that held (mostly) for a century. - **1815 - Napoleon exiled to Saint Helena**: Banished to the remote South Atlantic island in October 1815, Napoleon spent his final six years writing memoirs that burnished his legend far more effectively than his armies ever could. - **1830 - Belgium gains independence from Netherlands**: The Congress of Vienna had united Belgium and the Netherlands under one crown. Fifteen years later, Belgian nationalists revolted and secured their own kingdom, with Leopold I becoming the first king. - **1816 - British naval supremacy consolidated**: With France militarily exhausted, Britain's Royal Navy faced no rival for the next century. This dominance underwrote British imperial expansion and global trade routes through the 19th century. - **1820 - Rise of nationalist movements across Europe**: The rigid conservatism imposed by the Concert of Europe sparked liberal and nationalist uprisings from Spain to Greece. The Napoleonic Wars had awakened national consciousness; the post-Waterloo order couldn't suppress it. ## Then vs now - **French military personnel engaged**: 1815: ~72,000 → 2024: France military active duty: ~200,000 - Napoleon's Grande Armée had been decimated; this force was a fraction of his earlier strength - **Estimated casualties (single day)**: 1815: ~45,000 killed, wounded, or captured → 2013: Bloodiest day in recent conflict (Syria, 2013): ~1,500 casualties - Waterloo's casualty density remains staggering by modern standards - **Belgian population**: 1815: ~3.5 million → 2024: ~11.6 million - **Distance from Brussels to Waterloo battlefield**: 1815: 18 miles (by 1815 road) → 2024: 18 miles (modern measurement) - Unchanged geography; now a 30-minute drive ## Impact Napoleon's defeat at Waterloo on June 18, 1815, ended his Hundred Days comeback and sealed the restoration of the European monarchy. The battle reshaped the continent's power structure for a generation and confirmed that no single military genius could again dominate Europe unchecked. --- Canonical: https://recap.at/1815/battle-of-waterloo
