The First Battle of Wissembourg found Dubois in command of the Right Wing of the "Army of Rhine". His brigade commanders were Claude Ignace François Michaud and Claude Juste Alexandre Legrand. The Right wing included two battalions of the 37th Line Infantry and single battalions of the 11th Light, 40th, 75th and 79th Line Infantry. There were 10 National Guard battalions plus the 4th Dragoons and 2nd Chasseurs à Cheval. The French government dismissed the previous army commander but none of the generals wanted the post because they had seen such generals as Adam Philippe Custine and Jean Nicolas Houchard sent to the guillotine. In desperation, the representatives on mission selected Jean Pascal Carlenc, a good cavalry officer but incompetent as commander-in-chief. To add more trouble, on 10 October the army's chief of staff Henri Jacques Guillaume Clarke was dismissed for suspected sympathy with aristocrats. In the midst of this chaos, the 43,185-strong Coalition army under Dagobert Sigmund von Wurmser attacked on 13 October 1793. Dubois did not distinguish himself, withdrawing from his position when it was unnecessary. Carlec refused to order a counterattack unless authorized to do so by the political representatives, so the army fell back almost to Strasbourg. Dubois was replaced by Louis Desaix.
