Archduke Charles: The Man Who Beat Napoleon First
In May 1809, on the flat ground east of Vienna between the villages of Aspern and Essling, an epileptic Habsburg prince did what no commander in Europe had managed: he fought Napoleon Bonaparte across two days and forced him back over the Danube. It was the Emperor's first major defeat in the field. Six weeks later, on almost the same ground, the same Habsburg prince was beaten so comprehensively at Wagram that he resigned every office he held and never commanded again. Both men were Archduke Charles, and the distance between them is the puzzle of his career.
An Adopted Son of Vienna
Charles was born on 5 September 1771 in Florence, third son of the future Emperor Leopold II and Maria Luisa of Spain, and younger brother of the man who would rule as Francis II. He was raised not by his parents but in Vienna by his childless aunt, Archduchess Maria Christina, and her husband Albert of Saxe-Teschen, who adopted him. He suffered from epilepsy for his entire life, in an age that understood the condition barely at all and forgave physical weakness in a soldier not at all. He commanded armies anyway.
The Netherlands and the Rhine
He entered the army in 1792 and learned the trade fast and badly — which is to say in defeat as often as in victory. He led a brigade at Jemappes in 1792, distinguished himself at Aldenhoven and Neerwinden in 1793, and became Governor of the Habsburg Netherlands that year, losing the post when the French overran the Low Countries in 1794. He was on the losing side at Wattignies and at Fleurus.
Then came 1796, and the campaign that made him. Given command of all Austrian forces on the Rhine, Charles beat Jean-Baptiste Jourdan at Amberg, Würzburg and Limburg, then wheeled and beat Jean Victor Moreau at Wetzlar, Emmendingen and Schliengen. It is a campaign of interior lines executed at speed against two separate armies, and it has been called almost faultless. In 1797 he met Bonaparte himself for the first time in Friuli, was badly outmatched, and conducted the retreat with such skill that he brought the army out substantially intact — a performance that impressed the Austrian command more than some victories. In 1799 he beat Jourdan again at Ostrach and Stockach, invaded Switzerland, defeated Masséna at the First Battle of Zürich, and drove the French back across the Rhine after Mannheim.
The Reformer
His more consequential work was administrative. From 1801 as war minister, and formally from 1806 as Commander in Chief and head of the Council of War, Charles set about demolishing an eighteenth-century army and building a nineteenth-century one. He abolished lifetime military service and introduced conscription with exemptions. He ended corporal punishment by 1805. He rebuilt the neglected infantry, created reserve regiments, and established the Landwehr, a territorial force that embodied the nation-in-arms principle the French Revolution had made lethal. On 1 September 1805 he founded a modern general staff, divided into directorates for political correspondence, operations and service administration.
It was the right programme, and it was too slow. Conservative resistance inside the war council meant the reforms had produced little of tangible value by 1805, the year Austria went to war and lost catastrophically — Charles himself being beaten by Masséna at Caldiero in Italy. The army that fought in 1809 was his army, and it was the first Habsburg force in a generation that could stand against the French.
The Writer
Charles also wrote, at length and with authority. *Grundsätze der Kriegskunst für die Generale* appeared in 1806, *Grundsätze der Strategie* — built around a dissection of his own 1796 campaign — in 1814, and a history of the 1799 campaign in Germany and Switzerland in 1819. The doctrine they set out is cautious and geometric: strategy as the contest for decisive points, war as a calculation of positions. Clausewitz, reading them, objected to exactly this — the rigidity, the adherence to what he called geographic strategy, the reluctance to treat battle as the thing that decides.
1809
The war opened badly. Napoleon handled Charles roughly at Abensberg, Landshut and Eckmühl and took Vienna. Then, in May, the Emperor pushed across the Danube at Lobau to finish the Austrian army, and Charles caught him with his forces divided by the river. Over two days at Aspern-Essling the Austrians held, counter-attacked and forced Napoleon back. It was the first major setback of his career, and Europe noticed.
Charles did not follow it up. In July, Napoleon crossed again in strength, and at Wagram — two days of enormous, grinding slaughter on both sides — the Austrians were broken. Charles fell back, agreed an armistice at Znaim, and resigned all his military offices. He was thirty-seven. He received no command in the decisive campaigns of 1813 and 1814; Schwarzenberg led the Army of Bohemia instead.
Why Charles Is Called a Genius
The word has real backing here. Arthur Wellesley, who was not sentimental about foreign generals, called Charles the greatest general of his time. He is the only commander to have handed Napoleon a first major battlefield defeat, and he is with some justice described as the finest soldier the House of Habsburg ever produced. The specific quality on display at Aspern-Essling was tactical nimbleness under pressure: reading that Napoleon had over-committed across a river, committing before the window closed, and holding a defensive battle together for two days against the most aggressive army in Europe. Add to this a genuine organisational intelligence — the staff system, the Landwehr, the abolition of lifetime service and the lash — and a body of strategic writing serious enough that Clausewitz thought it worth attacking.
The counter-case is unusually well documented, and it is a case about temperament rather than capacity. Charles was compulsively cautious. His strategic doctrine was defensive and positional, and against an opponent who understood that battles, not places, end wars, caution was a losing method. Clausewitz's charge of geographic rigidity is the theoretical version; Wagram is the practical one. His reforms, correct in design, moved too slowly to save Austria in 1805. And there is the strange verdict, repeated by his biographers, that the theory and practice of Archduke Charles form one of the most curious contrasts in military history — unreal on the page, vividly active in the field. A man whose written doctrine does not describe his own best work is not quite a first-rank thinker about war. Call him a superb battlefield commander, an excellent institutional reformer, and a mediocre theorist whom history has flattered by association with the one afternoon he outfought Bonaparte.
Legacy
Charles married Princess Henrietta of Nassau-Weilburg in September 1815, succeeded to the duchy of Saxe-Teschen in 1822, was floated for the Belgian throne in 1830, and lived out a long retirement. He died in Vienna on 30 April 1847 and lies in the Imperial Crypt. In 1860 Vienna put him on the Heldenplatz on horseback, opposite Prince Eugene — the two soldiers the Habsburgs chose to remember. The army he rebuilt outlasted him by seventy years. The reputation rests, and will always rest, on two days in May by the Danube when the man who could not be beaten was.
