On 25 February 1814, Napoleon decided to leave the pursuit of the Army of Bohemia to his subordinates. The emperor assigned Jacquinot's division and Kellermann's corps to Marshal Nicolas Oudinot while distributing other cavalry units to MacDonald. Jacquinot's division fought at the Battle of Bar-sur-Aube on 27 February and at the Battle of Saint-Dizier on 26 March. During Napoleon's bid to cut the Allied communications in the last week of March, he sent the light cavalry of Jacquinot and Hippolyte Piré ahead of the army, provoking panic. At Saint-Dizier, Napoleon's cavalry routed Ferdinand von Wintzingerode's 10,000 cavalry, but it proved to be a hollow victory because the Allied generals ignored the threat to their supply line and marched on Paris. The Allies won the Battle of Paris on 30 March 1814 and this event ended the war. By 4 April the 4th Cavalry Division had shrunk badly. Ameil's brigade counted only 331 officers and men while Wolff's brigade numbered only 244.
