The II Cavalry Corps of the Grande Armée was a French military unit that existed during the Napoleonic Wars. It was first formed in December 1806, but only enjoyed a brief existence under Marshal Jean-Baptiste Bessières. The II Cavalry Corps was reconstituted for the invasion of Russia in 1812 and commanded by General Louis-Pierre Montbrun who was killed in battle, as was his successor a few hours later. During the War of the Sixth Coalition, General Horace François Bastien Sébastiani de La Porta led the II Cavalry Corps in 1813, while General Antoine-Louis Decrest de Saint-Germain led the corps in 1814. During the Hundred Days, Emperor Napoleon Bonaparte raised the corps again and entrusted it to General Rémi Joseph Isidore Exelmans.
