While in Paris, he was promoted to the rank of lieutenant-general. In October he returned to the Army of the North, where Dumouriez had begun a march into the Austrian Netherlands (now Belgium). Louis Philippe again commanded a division. On 6 November 1792, Dumouriez chose to attack an Austrian force in a strong position on the heights of Cuesmes and Jemappes to the west of Mons. Louis Philippe's division sustained heavy casualties as it attacked through a wood, retreating in disorder. Louis Philippe rallied a group of units, dubbing them "the battalion of Mons" and pushed forward along with other French units, finally overwhelming the outnumbered Austrians.
