On 14 March, Treillard led a 2,400-man reconnaissance toward Villenauxe-la-Grande which skirmished with the Allies before being pushed back. After his defeat at the Battle of Arcis-sur-Aube on 20–21 March, Napoleon crossed to the east bank of the Marne River. General Hippolyte Piré's light cavalry division raced toward Bar-sur-Aube while Jacquinot's division headed toward Chaumont-la-Ville. On 26 March, Napoleon defeated General Ferdinand von Wintzingerode at the Battle of Saint-Dizier. On the right flank, Kellermann led the pursuit. When Napoleon decided to march toward Paris, the divisions of Jacquinot and Piré were in the lead. Trelliard's division and an infantry division were the rearguard. On 2 April, the divisions of Trelliard and Jacquinot numbered much less than when the corps was first formed in February. The brigades of Jacquinot's division appeared to have largely switched units with the 2nd and 12th Hussars, the 13th, 21st, 22nd, and 28th Chasseurs in Ameil's 7th Brigade, and the 4th, 5th, 10th, and 15th Chasseurs in Wolff's 8th Brigade.
