On 30 September 1793 Moreaux was offered command of the "Army of the Moselle" but refused. In the Second Battle of Wissembourg in December 1793, Moreaux led a division in Lazare Hoche's "Army of the Moselle". His division included the 1st Battalions of the 30th, 44th and 81st Line Infantry Demi Brigades and the "Lot" and "Ardennes" Volunteers, the 2nd Battalions of the 54th Line, 99th Line and "Loiret", the 4th and 6th Battalions of the "Haute-Saone", the 5th Battalion of the "Orne", three squadrons of the 10th Cavalry and four squadrons of the 9th Chasseurs à Cheval Regiments. When Hoche became ill at the end of January 1794, Moreaux temporarily took command. Two months later Jean-Baptiste Jourdan succeeded Hoche in command and the army pulled back to a position between Thionville and Sarrebruck.
