The Grande Armée (French pronunciation: [ɡʀɑ̃d aʀme]; French for Great Army) was the army commanded by Napoleon during the Napoleonic Wars. From 1805 to 1809, the Grande Armée scored a streak of historic victories that gave the French Empire an unprecedented grip on power over the European continent. Widely acknowledged to be one of the greatest fighting forces ever assembled, it suffered terrible losses during the French invasion of Russia in 1812 and never recovered its tactical superiority after that campaign.
It was renamed in 1805 from the army that Napoleon had assembled on the French coast of the English Channel for the proposed invasion of Britain. Napoleon later deployed the army east in order to eliminate the threat of Austria and Russia, which were part of the Third Coalition assembled against France. Thereafter, the name was used for the principal French army deployed in the Campaigns of 1805 and 1807, where it got its prestige, and 1809, 1812, and 1813–14. In practice, however, the term, Grande Armée, is used in English to refer to all of the multinational forces gathered by Napoleon I in his campaigns of the early 19th century (see Napoleonic Wars).
