The Grande Armée (pronounced [ɡʁɑ̃d aʁme]; French for 'Grand Army') was the primary field army of the French Imperial Army during the Napoleonic Wars. Commanded by Napoleon, from 1804 to 1808 it won a series of military victories that allowed the First French Empire to exercise unprecedented control over most of Europe. Widely acknowledged to be one of the greatest fighting forces ever assembled, it suffered catastrophic losses during the disastrous French invasion of Russia, after which it never recovered its strategic superiority and ended its military career with a total defeat during the Hundred Days in 1815.
The Grande Armée was formed in 1804 from the Armée des côtes de l'Océan (Army of the Ocean Coasts) more commonly referred to as the Armée d'Angleterre (Army of England), a field army of over 100,000 men assembled for Napoleon's planned invasion of the United Kingdom. He subsequently led the field army to Central Europe and defeated Austrian and Russian forces as part of the War of the Third Coalition. Thereafter, the Grande Armée was the principal field army deployed in the War of the Fourth Coalition, Peninsular War and War of the Fifth Coalition, where the French army slowly lost a large portion of its veteran soldiers, strength and prestige, and in the invasion of Russia, War of the Sixth Coalition and Hundred Days. The term Grande Armée is often used to refer to multinational armies led by Napoleon in his campaigns; however, during the War of the Fifth Coalition and the Waterloo campaign (part of the Hundred Days), other formations were led by him de facto, namely the Army of Germany and the Army of the North, respectively.
