The VI Corps of the Grande Armée was a French military unit that existed during the Napoleonic Wars. It was formed at the Camp de Boulogne and assigned to Marshal Michel Ney. From 1805 to 1811, the VI Corps fought under Ney's command in the 1805 Austrian Campaign: War of the Third Coalition, Prussian Campaign of 1806 and Polish Campaign of 1807 of the War of the Fourth Coalition. General Jean Gabriel Marchand was in charge of the corps for a period when Ney went on leave. The VI Corps was revived in 1812 for the French invasion of Russia and placed under Marshal Laurent Gouvion Saint-Cyr. It consisted entirely of Bavarian soldiers at that time. During the disastrous retreat from Moscow, the corps was virtually destroyed. In 1813, during the War of the Sixth Coalition, it was rebuilt and reorganized with French troops. Marshal Auguste de Marmont took command of the corps and managed it until Napoleon's abdication in 1814. It took part in many battles including Dresden and Leipzig in 1813. During the War of the Seventh Coalition, General Georges Mouton commanded the VI Corps at the Battle of Waterloo.

La Grande Armée 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 Peninsular War followed by the invasion of Russia in 1812, after which it never recovered its strategic superiority and ended in total defeat for Napoleonic France by the Peace of Paris in 1815.
