The Army of the Rhine (Armée du Rhin) was formed in December 1791, for the purpose of bringing the French Revolution to the German states along the Rhine River. During its first year in action (1792), under command of Adam Philippe Custine, the Army of the Rhine participated in several victories, including Mainz, Frankfurt and Speyer. Subsequently, the army underwent several reorganizations and merged with the Army of the Moselle to form the Army of the Rhine and Moselle on 20 April 1795.

The Army of the Rhine (Armée du Rhin) was one of the main French Revolutionary armies operated in the Rhineland theater, principally in the Rhine River valley, from 1791 to 1795. At its creation, the Army of the Rhine had 88,390 men. It was formed on 14 December 1791, to defend France's eastern frontier in conjunction with two other armies, the Army of the North and the Army of the Center (name changed in October 1792 to Army of the Moselle). These armies were subdivided, fresh forces were raised and gradually grew until, by 30 April 1793, eleven armies encircled France on its coastal and the land frontiers. In October 1792, a portion of the army was used to form the Army of the Vosges but these units rejoined the Army of the Rhine on 15 March 1793.

In the first months of fighting, victories for France were few. Although Custine had succeeded in driving the ecclesiastical authorities from the Swiss village of Porrentruy by 27 April 1792, this singular victory was accomplished largely through the enterprises of a local uprising assisted by some advanced guard and it was the last French victory for several weeks: subsequently, the borders of France had been assaulted by the Habsburgs and their allies. At Mons (18–29 April 1792), Tournay (29 April 1792), Bavay (17 May 1792), Rumégies (19 May 1792), Florennes 28 May 1792, and La Glisuelle, a village 5 kilometers (3 mi) north of Maubeuge (11 June 1792), Austrian skirmishers repeatedly defeated French forces.
