The III Corps of the Grande Armée was a French military unit that existed during the Napoleonic Wars. The corps came to prominence between 1805 and 1809 under the command of Marshal Louis-Nicolas Davout, when it repeatedly scored impressive victories single-handedly or in conjunction with other French forces. Napoleon called it "My tenth legion", in reference to Julius Caesar's finest unit, the X Equestris. Troops from III Corps then took part in many battles in Poland, during the War of the Fourth Coalition, e.g. Czarnowo, Pultusk, Golymin, Eylau.. These troops were later reorganized as the I Corps and included French, German, and Polish units.
