; ) was the main military component of the French Imperial Army commanded by Emperor Napoleon Bonaparte during the Napoleonic Wars. From 1804 to 1808, it won a series of military victories that allowed the French Empire to exercise unprecedented control over most of Europe. Widely acknowledged to be one of the greatest fighting forces ever assembled, it suffered enormous losses during the disastrous invasion of Russia in 1812, after which it never recovered its strategic superiority.
The Grande Armée was formed in 1804 from the L'Armée des côtes de l'Océan (Army of the Ocean Coasts), a force of over 100,000 men that Napoleon had assembled for the proposed invasion of Britain. Napoleon later deployed the army in Central Europe to eliminate the combined threat of Austria and Russia, which were part of the Third Coalition formed against France. Thereafter, the Grande Armée was the principal military force deployed in the campaigns of 1806/7, the French invasion of Spain, and 1809, where it earned its prestige, and in the conflicts of 1812, 1813–14, and 1815. In practice, however, the term Grande Armée is used in English to refer to all the multinational forces gathered by Napoleon in his campaigns.
In addition to its size and multinational composition, the Grande Armée was known for its innovative formations, tactics, logistics, and communications. While most contingents were commanded by French generals, except for the Polish and Austrian corps, soldiers could climb the ranks regardless of class, wealth, or national origin.
Upon its formation, the Grande Armée consisted of six corps under the command of Napoleon's marshals and senior generals. When the Austrian and Russian armies began preparations to invade France in late 1805, the Grande Armée was quickly ordered across the Rhine into southern Germany, leading to Napoleon's victories at Ulm and Austerlitz. The French Army grew as Napoleon seized power across Europe, recruiting troops from occupied and allied nations; it reached its peak of one million men at the start of the Russian campaign in 1812, with the Grande Armée reaching its height of 413,000 French soldiers and over 600,000 men overall when including foreign recruits.
In summer of 1812, the Grande Armée marched slowly east, and the Russians fell back with its approach. After the capture of Smolensk and victory at Borodino, the French reached Moscow on 14 September 1812. However, the army was already drastically reduced by skirmishes with the Russians, disease (principally typhus), desertion, heat, exhaustion, and long communication lines. The army spent a month in Moscow but was ultimately forced to march back westward. Cold, starvation, and disease, as well as constant harassment by Cossacks and Russian partisans, resulted in the Grande Armée utter destruction as a fighting force. Only 120,000 men survived to leave Russia (excluding early deserters); of these, 50,000 were Austrians, Prussians, and other Germans, 20,000 were Poles, and just 35,000 were French. As many as 380,000 died in the campaign.
Napoleon led a new army during the campaign in Germany in 1813, the defence of France in 1814, and the Waterloo campaign in 1815, but the Grande Armée would never regain its height of June 1812. In total, from 1805 to 1813, over 2.1 million Frenchmen were conscripted into the French Imperial Army.

1804–1806
The Grande Armée was originally formed as L'Armée des côtes de l'Océan (Army of the Ocean Coasts) intended for the invasion of Britain, at the port of Boulogne in 1804. Following Napoleon's coronation as Emperor of the French in 1804, the Third Coalition was formed against him and the Grande Armée turned its sights eastwards in 1805. The army left Boulogne in late August and through a rapid marches, surrounded General Karl von Mack's isolated Austrian Army at the fortress of Ulm. The Ulm campaign, as it came to be known, resulted in 60,000 Austrian prisoners at the cost of just 2,000 French soldiers. By November, Vienna was taken but Austria refused to capitulate, maintaining an army in the field. In addition, its ally Russia had yet to commit to action. The war would continue for a while longer. Affairs were decisively settled on 2 December 1805 at the Battle of Austerlitz, where the numerically inferior Grande Armée routed a combined Russo-Austrian army led by Russian Emperor Alexander I. The stunning victory led to the Treaty of Pressburg on 26 December 1805, with the dissolution of the Holy Roman Empire the following year.
