 Initially, the Army included five future Marshals of France: Jean-Baptiste Jourdan, its commander-in-chief, François Joseph Lefebvre, Jean-Baptiste Drouet, Laurent de Gouvion Saint-Cyr, and Édouard Adolphe Casimir Joseph Mortier. After the defeat at Ostrach, the Army was reorganized and command shifted to another future marshal, André Masséna.
