The Algerian and Moroccan units of the 1st Free French Division gave birth to the French Expeditionary Corps under the command of Général Alphonse Juin, future Maréchal de France, and Général Joseph de Goislard de Monsabert. They were also instrumental in the Battle of Monte Cassino. There, the 3rd Division d'Infanterie Algérienne (3rd DIA), and the Groupement des Tabors Marocains of Général Augustin Guillaume were recognized in breaking through the German defences of the Gustav Line.
