The II Corps of the Grande Armée was a French military unit that existed during the Napoleonic Wars.
At its formation in 1805, General Auguste de Marmont was appointed commander of the II Corps.
Batavian Division, commanding officer Général de Division Count Jean-Baptiste Dumonceau[1]
The corps participated in the Ulm campaign before advancing southeast to serve as a flank guard. Still under Marmont, the troops then served as the garrison of the Illyrian Provinces until 1809 when they became the Army of Dalmatia and later XI Corps.
Meanwhile, a parallel II Corps was created in 1809 to fight against Austria. The formation was led first by Marshal Nicolas Oudinot, then by Marshal Jean Lannes who was fatally wounded at Aspern-Essling. Oudinot then took over II Corps again and won his marshal's baton at Wagram in July 1809.
