IX Corps (Grande Armée)
The IX Corps of the Grande Armée was a French military unit that existed during the Napoleonic Wars. The corps was first formed in 1806 from German troops allied with the First French Empire, with Emperor Napoleon I appointing his brother Jérôme Bonaparte as commander. During 1807, elements of the corps besieged several Prussian fortresses. The corps was revived as an all-Saxon unit in 1809 and leadership given to Marshal Jean-Baptiste Bernadotte. The corps fought at Linz-Urfahr and Wagram.
In 1810, a new IX Corps appeared in Spain led by General Jean-Baptiste Drouet. The corps was in action at the Battle of Fuentes de Oñoro in 1811 before being discontinued. The IX Corps was reformed in 1812 for the French invasion of Russia and Marshal Claude Victor-Perrin was assigned to lead it. Victor's troops fought in several actions, most notably at the Battle of Berezina in November. The formation was re-established in 1813 with Marshal Pierre Augereau as its commander and fought at Leipzig.Order of battle
