Wipedia says: The four sculptural groups at the base of the Arc are The Triumph of 1810 (Jean-Pierre Cortot), Resistance and Peace (both by Antoine Étex) and the most renowned of them all, Departure of the Volunteers of '92 commonly called La Marseillaise (François Rude). The face of the allegorical representation of France calling forth her people on this last was used as the belt buckle for the seven-star rank of Marshal of France.
