During the retreat after Leipzig, Milhaud and Lhéritier led the 15th and 18th Dragoons in action at Eckartsberga on 22 October. The French successfully parried an attempt by General Ignaz Gyulai's III "Armeekorps" to cut off their escape route. The 19th and 20th Dragoons and the 14th and 27th "Chasseurs-à-Cheval" from the V Cavalry Corps participated in the Battle of Hanau on 30–31 October. By late November, Milhaud's V Cavalry Corps covered the Left Bank of the Rhine from Mainz in the north to near Landau in the south. The corps numbered 3,973 horsemen of whom 300 patrolled the river every day between Mainz and Worms.
