On 30 October Curial was heavily involved in defending against the Austro-Bavarian army attempting to cut off the retreat of the French army at the Battle of Hanau. As a reward for his services during this battle, he received the Grand Cross of the Order of the Reunion. Curial took part in all the battles against the allied forces as they pushed into France, and particularly distinguished himself at the battles of Vauchamps and Craonne under the emperor, and the Battle of Paris under General Mortier. The Emperor created him count of the Empire on 22 March 1814.
