Still in the corps of Soult, Legrand fought at the battles of Jena in 1806 and Eylau in 1807. During the 1809 campaign, he led a division under Marshal Andre Massena in the battles of Ebelsberg, Aspern-Essling and Wagram. In Napoleon's 1812 invasion of Russia, he fought in Marshal Oudinot's II Corps at Polotsk. He was badly wounded during the crossing of the Berezina River but survived the disastrous winter retreat.
