War of the Third Coalition

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.

War of the Fifth Coalition

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.

Russian campaign

Still commanded by Oudinot, the corps took part in the invasion of Russia in 1812, at which point its size was roughly 40,000 men.
