On 6 January 1814, Meunier's 1st Young Guard Voltiguer Division, with 5,250 men, was located near Nancy. On 11 January, the Allies roughly handled Guillaume-Charles Rousseau's brigade of the division during its retreat from Épinal. Soon after, Marshal Michel Ney arrived to take command of Meunier's division and other units. On 25 January 1814, Meunier's 1st Young Guard Division had two brigades, as follows. Jean Étienne Clément-Lacoste's brigade consisted of the 1st Voltiguer Regiment, 657 men, and the 2nd Voltiguer Regiment, 940 men. Rousseau's brigade was composed of the 3rd Voltiguers, 1,263 men, and the 4th Voltiguers, 1,144 men. Each regiment had two battalions and 140 gunners and artillery drivers were attached. At the Battle of Brienne on 29 January, Meunier's division attacked the village of Brienne-le-Château after nightfall but was unable to oust its Russian defenders. The division numbered about 3,000 men at the Battle of La Rothiere on 1 February. Meunier's troops became involved in the left flank fighting before being forced to withdraw.
