Six Phases of European Convulsion: From the Cannonade of Valmy to the Squares at Waterloo, How Twenty-Three Years of War Made and Unmade an Empire
Europe, 20 April 1792–17 October 1797 • The Revolution Defends Itself, Then Strikes
In April 1792 the Legislative Assembly declared war on "the King of Bohemia and Hungary" — against Brissot's expectation that the war would unite the country and against Robespierre's expectation that it would strangle the revolution. It did neither cleanly. The Cannonade of Valmy on 20 September 1792 saved the Republic; Goethe, present, wrote: "From this place and from this day forth begins a new era in the history of the world." By 1797 a young general named Bonaparte had broken Austria in the Italian campaigns and dictated peace at Campo Formio.
1753–1823 • Member of the Committee of Public Safety
The mathematician-engineer who turned the chaotic Republic into a war-making machine. Author of the levée en masse decree of 23 August 1793 that conscripted all unmarried men 18–25, he organised fourteen field armies, directed strategy from Paris, and survived the Thermidorian reaction. Robespierre called him "the dictator of victories" — but only behind closed doors.
Co-victor at Valmy and victor at Jemappes. Defected to the Austrians in 1793 after his offensive into the Netherlands collapsed — and after his political patrons fell to the Jacobins.
Commander at Valmy. Loyal to whatever government held Paris. Made a Marshal of the Empire in 1804.
Initially opposed to the war; once it was unavoidable, he weaponised it through the Committee of Public Safety. Executed 28 July 1794, ending the Terror.
Habsburg field commander. Defeated French armies at Amberg and Würzburg (1796). The first Coalition general to consistently outfight French armies of equal size.
The First Coalition demonstrated that a citizen army organized by the levée en masse could defeat the professional armies of dynastic Europe. The era invented modern conscription, mass mobilisation, and the reconnaissance balloon — and produced the man who would dominate the next eighteen years.
Egypt and Syria, 19 May 1798–31 August 1801 • A Strategic Failure That Founded Egyptology
In 1798 the Directory dispatched Bonaparte to Egypt with a dual purpose: strangle British India by cutting the Mediterranean route, and remove the dangerous young general from Paris. The army won at the Pyramids; the navy was annihilated by Nelson at the Nile. Bonaparte's siege of Acre failed. Yet his 167 accompanying savants — mathematicians, archaeologists, naturalists — produced the 23-volume Description de l'Égypte and recovered the Rosetta Stone, founding modern Egyptology even as the campaign failed strategically.
1769–1821 • Twenty-eight at the Pyramids
Sailed from Toulon on 19 May 1798 with 35,000 troops, took Malta en route, and landed at Alexandria on 1 July. He defeated the Mamluks at the Pyramids three weeks later. Trapped in Egypt by Nelson's destruction of his fleet, he abandoned his army on 22 August 1799 to seize power in Paris — the Coup of 18 Brumaire.
Vice-Admiral. Annihilated the French fleet at the Nile. The victory cut Bonaparte off, secured British naval supremacy in the Mediterranean, and made Nelson a national hero.
Commander left in Egypt by Bonaparte. Defeated the Ottomans at Heliopolis (March 1800), then was assassinated by a Syrian student in Cairo three months later.
Chief of the savants. His Voyage dans la Basse et Haute Égypte (1802) launched European Egyptomania. The Description de l'Égypte ran to 23 volumes.
Linguist who deciphered the Rosetta Stone in 1822 — founding modern Egyptology and giving meaning, retrospectively, to the campaign's intellectual legacy.
The Egypt campaign was Bonaparte's only major strategic defeat before 1812 — and his political springboard. The expedition's intellectual legacy — the founding of Egyptology — remains its most enduring product, an achievement quite separate from its military failure.
Europe, 1803–1806 • Britain Rules the Sea, France Rules the Land
In 1805 Pitt the Younger assembled the Third Coalition: Britain, Russia, Austria, Sweden. Napoleon, now Emperor, abandoned plans to invade England and marched the Grande Armée from Boulogne to the Danube in 33 days. He surrounded an Austrian army at Ulm (October 1805), then crushed the combined Austro-Russian army at Austerlitz on the first anniversary of his coronation (2 December 1805) — "the Battle of the Three Emperors." Six weeks earlier, Nelson had destroyed the Franco-Spanish fleet at Trafalgar but died in the moment of victory.
1769–1821 • Crowned 2 December 1804
The crowned Emperor was a different commander than the young general at the Pyramids: more cautious, more strategic, capable of operational masterpieces like the Ulm campaign. Austerlitz was his self-described "best battle," fought on the first anniversary of his coronation, against the Tsar of Russia and the Holy Roman Emperor in person.
Killed at his greatest victory. His tactic at Trafalgar — perpendicular attack in two columns — broke 250 years of line-ahead orthodoxy and ensured British naval supremacy until 1918.
Russia's young emperor (b. 1777). Persuaded against the more cautious advice of Kutuzov to attack at Austerlitz. Ten years and three coalitions later he would ride into Paris.
French admiral commanding at Trafalgar. Captured, paroled, then died at Rennes in 1806 — reportedly suicide by stabbing.
British PM. Architect of the Third Coalition. After Austerlitz he reportedly said of his map of Europe, "Roll it up; we shall not need it these ten years." He died in January 1806.
The Trafalgar/Austerlitz pairing is one of military history's iconic juxtapositions: in six weeks, France lost the war at sea and won it on land. The strategic stalemate that resulted produced the Continental System, the Peninsular War, and ultimately the disastrous campaign in Russia.
Iberia, 1807–1814 • Wellington, Guerrillas, and the Word "Guerrilla"
In 1807 Napoleon invaded Portugal to enforce the Continental System; in 1808 he took the Spanish throne for his brother Joseph. The Spanish people rose. Madrid massacre 2 May 1808; Baylén surrender 22 July; British landings under Sir Arthur Wellesley starting in August. The result was a seven-year drain on French resources — the "Spanish ulcer," Napoleon called it — that Wellington exploited from behind the Lines of Torres Vedras at Lisbon. The word "guerrilla" entered English from this war.
1769–1852 • The Iron Duke
Born in the same year as Napoleon. Made his name in India before Iberia. Master of defensive battle (Busíaco, Salamanca, Vitória), the reverse-slope, and the use of allied irregulars. Famous for his attention to logistics: "an army marches on its stomach" was a saying he made literally true.
"L'enfant chéri de la victoire." Defeated by Torres Vedras and the Portuguese scorched-earth retreat. Returned to France ill and disgraced; never received another command.
Most able French commander in Spain. Led the rearguard from Salamanca and the defence of southern France. Wellington's only consistent equal in the Peninsula.
Spanish guerrilla chief in Navarre. Commanded ~3,500 fighters who tied down 30,000 French. Survived the war, was exiled by Ferdinand VII, returned, and died a Liberal hero.
British general who commanded the Portuguese army (rebuilt and trained to British standards). Fought Albuera (1811) — the bloodiest infantry combat of the war.
The Peninsular War invented modern guerrilla warfare and demonstrated that occupation of a hostile civilian population was strategically corrosive. Napoleon's "Spanish ulcer" cost the empire what it gained at Tilsit; without it, the Russian campaign of 1812 would have been better supplied and reinforceable.
Russia, 24 June–14 December 1812 • The Largest Army Ever Assembled, Returned a Third
In June 1812, Napoleon assembled the largest army Europe had ever seen — 685,000 men of two dozen nationalities — and crossed the Niemen into Russia. Tsar Alexander withdrew, evading battle while burning supplies. Borodino on 7 September cost both sides ~75,000 casualties combined. Moscow was occupied 14 September; that night Russian incendiaries set the city ablaze. Napoleon waited five weeks for peace negotiations that never came, then began the long retreat. The grand army that crossed the Berezina in November was a third of what had begun. Cold, hunger, and Cossacks did the rest.
1745–1813 • Hero of 1812
One-eyed veteran of every Russian war back to the Crimea. Sixty-seven and corpulent at the start of the campaign. Tolstoy's hero in War and Peace. His strategy of withdrawal, contested battle at Borodino, and the surrender of Moscow saved Russia by destroying the Grande Armée in pursuit. Died March 1813, aged 67, on the road to Berlin.
Refused all overtures from Napoleon during the occupation of Moscow. His implacability turned a disastrous summer into a strategic victory. Marched into Paris in 1814.
"The bravest of the brave." Commanded the rearguard during the retreat. The last man to recross the Niemen, Russian musket in hand, was reportedly Ney himself.
Governor of Moscow. Probably ordered the burning of his own city — though he later denied it. The act ended Napoleon's hopes of negotiated peace.
Russian Minister of War. Architect of the strategic withdrawal. Replaced as commander after Smolensk; rehabilitated and led Russian armies into Germany in 1813.
The single most catastrophic campaign in pre-twentieth-century European history. Charles Joseph Minard's 1869 graphic of the army's diminishing strength remains a landmark of data visualisation. The campaign shifted military thinking toward logistics, weather, and overextension — lessons revisited bitterly in 1941.
Belgium, 20 March–18 June 1815 • Napoleon's Last Hundred Days
Napoleon escaped from Elba on 26 February 1815 and landed near Antibes 1 March with 1,026 men. By 20 March he was in the Tuileries; Louis XVIII had fled. The Allies declared him an outlaw. Napoleon raced to defeat Wellington's Anglo-Dutch army and Blücher's Prussians before they could combine. He fought Blücher at Ligny and Wellington at Quatre Bras simultaneously on 16 June; on the 18th, at Mont-Saint-Jean south of Brussels, the Anglo-Dutch held until Blücher arrived. The Imperial Guard broke; the Empire was over.
1742–1819 • "Marshal Forwards"
Seventy-two-year-old Prussian commander whose pugnacious aggression complemented Wellington's defensive caution. Defeated at Ligny on 16 June, he marched 25 km to Waterloo two days later despite a horse falling on him — arriving at the decisive moment. His pursuit through the night completed Napoleon's destruction.
Charged with intercepting Blücher; failed to march toward the cannon at Waterloo. Spent the rest of his life writing memoirs defending himself.
"The bravest of the brave." Led the disastrous unsupported cavalry charges at Waterloo. Tried for treason after the Restoration; executed by firing squad 7 December 1815.
Future William II of the Netherlands. Twenty-three years old, second-in-command at Waterloo. Wounded in the shoulder by a French ball; the bullet kept and displayed.
Wellington's cavalry commander. Lost a leg in the final hour to a French cannonball — "By God, sir, I've lost my leg!" "By God, sir, so you have!" became the war's most famous exchange.
Waterloo entered the English language as a metaphor for total defeat. The Vienna settlement froze European boundaries for nearly a century. Napoleon's legacy — the Civil Code, the metric system, lycées, the Bank of France, and the modern administrative state — outlived his empire and shaped the next two centuries of European life.
| Phase | Years | Decisive Battle | French Strength | Outcome | Result for France |
|---|---|---|---|---|---|
| 1st Coalition | 1792–97 | Lodi/Rivoli | ~750,000 (levée) | Campo Formio | Victory |
| Egypt | 1798–1801 | Pyramids/Nile | 35,000 | Surrender at Alexandria | Strategic loss |
| 3rd Coalition | 1803–06 | Austerlitz | ~200,000 | Pressburg, dissolution of HRE | Triumph |
| Peninsular | 1807–14 | Salamanca/Vitória | ~300,000 tied down | French expelled | "Spanish ulcer" |
| Russia | 1812 | Borodino | 685,000 | ~100,000 returned | Catastrophe |
| Hundred Days | 1815 | Waterloo | ~280,000 | Saint Helena exile | Empire ended |
The 1793 conscription decree transformed warfare. By committing entire societies, France could field armies that absorbed losses inconceivable to dynastic monarchies. Eventually all Europe imitated; by 1813 Prussian and Russian conscription matched French.
Trafalgar (1805) confirmed permanent British naval supremacy. Austerlitz (1805) confirmed French land supremacy. Neither side could finish the other; the Continental System and the Peninsular War were Napoleon's attempts to break the impasse.
Britain led seven coalitions (1793, 1798, 1805, 1806, 1809, 1813, 1815). The first six failed; the seventh succeeded only after Russia's 1812 hammer-blow had shattered the Grande Armée. Persistence finally won.
Napoleon's enduring legacy was administrative, not military: the Civil Code (1804), the metric system, the lycée system, prefectures, the Bank of France. These reshaped European life longer than any battle.
The Peninsular War invented the word "guerrilla." The Russian campaign was won by burning everything along the route. Mass national resistance — an idea unknown to ancien régime warfare — became modern strategy.
The Vienna settlement (1815) and its enforcement by the Concert of Europe kept the great powers from total war for ninety-nine years. The system's success and final failure (1914) defined nineteenth-century international order.
