Under the overall command of François Étienne de Kellermann, the VI Corps and a dragoon division overcame Del Parque's army at the Battle of Alba de Tormes on 26 November in a lopsided victory. While the cavalry inflicted most of the damage, the infantry arrived in time to capture the bridge and town. At the time of the Siege of Ciudad Rodrigo from April to July 1810 and the subsequent Siege of Almeida from July to August, Marcognet led a brigade in Marchand's 1st Division.
