The Army of the Rhine and Moselle (French: Armée de Rhin-et-Moselle) was one of the field units of the French Revolutionary Army. It was formed on 20 April 1795 by the merger of elements of the Army of the Rhine and the Army of the Moselle. The Army of the Rhine and Moselle campaigns provided experience for a cadre of young officers. In his five-volume analysis of the Revolutionary Armies, Ramsey Weston Phipps called the Army of the Rhine and Moselle a "school for marshals", to emphasize the importance of experience under these conditions in training the future leadership of Napoleon's army.
