The Army of the Ardennes (armée des Ardennes) was a French Revolutionary Army formed in 1792 by splitting off the right wing of the Army of the North, commanded from July to August that year by La Fayette. From July to September 1792 General Dumouriez also misused the name Army of the Ardennes for the right wing of what was left of the Army of the North after the split, encamped at Sedan.
