Building on the Directory’s conscription law of September 1798, the Napoleonic regime, after considerable trial and error, had created the mechanisms for imposing on the citizens of France and the annexed territories the distasteful obligation of military service. Each year the Ministry of War Administration assigned a quota of conscripts for every département. Using communal birth registers, the mayor of each commune compiled a list of men reaching the age of 19 that year. After a preliminary examination to screen out the manifestly unfit and those below the minimum height of 5 feet 1 inch (1.5 metres), the young men drew numbers in a lottery at the cantonal seat. Doctors in the departmental capitals later ruled on other claims for medical exemptions, and in all about a third of the youths avoided military service legally as physically unfit. Though married men were not exempt from the draft, two other means of avoiding induction remained, apart from drawing a high number: the wealthy could purchase a replacement, and the poor could flee.

For Napoleon’s prefects, the annual conscription levy was the top priority and draft evasion the number-one problem in most départements. Persistence, routine stepped-up policing, and coercion gradually overcame the chronic resistance. Napoleon had begun by drafting 60,000 Frenchmen annually, but by 1810 the quota hit 120,000, and the first of many “supplementary levies” was decreed to call up men from earlier classes who had drawn high numbers. In January 1813, after the Russian disaster, Napoleon replenished his armies by calling up the class of 1814 a year early and by repeated supplementary levies. Because he could still rely on his conscription machine, Napoleon consistently rebuffed offers by the allies to negotiate peace. Only after he lost the decisive Battle of Leipzig in October 1813 and was driven back across the Rhine did the machine break down. His call of November 1813 for 300,000 more men went largely unfilled. With the troops at his disposal, the emperor fought the Battle of France skillfully, but he could not stop the allies. Shortly after Paris fell, he abdicated, on April 6, 1814, and departed for the island of Elba. France was reduced to its 1792 borders, and the Bourbons returned to the throne. Altogether—along with large levies of Italians, Germans, and other foreigners from the annexed territories and satellite states—nearly 2,500,000 Frenchmen had been drafted by Napoleon, and at least 1,000,000 of these conscripts never returned, roughly half that number being casualties and the other half imprisoned or missing.

The most sympathetic explanation for Napoleon’s relentless aggression holds that he was responding to the irreducible antagonism of Britain: French power and glory were the only antidotes to John Bull’s arrogance. Others have argued that Napoleon’s vendetta against Britain was merely a rationalization for a mad 10-year chase across Europe to establish a new version of Charlemagne’s empire. This “imperial design” thesis, however, makes sense only in 1810, as a way Napoleon might have organized his conquests and not as the motivation for them. (Only retrospectively did Napoleon write, “There will be no repose for Europe until she is under only one Head…an Emperor who should distribute kingdoms among his lieutenants.”) In the end, one is thrown back on the explanation of temperament. In his combination of pragmatism and insatiable ambition, this world-historic figure remains an enigma. Increasingly “aristocratic” at home and “imperial” abroad, Napoleon was obviously something more than the “general of the Revolution.” And yet, with civil code in one hand and sabre in the other, Napoleon could still be seen by Europeans as a personification on both counts of the French Revolution’s explosive force.
