At the start of the Six Days' Campaign, Ney's corps included Meunier's division with 4,133 soldiers and Philibert Jean-Baptiste Curial's 2nd Young Guard Division with 2,840 men. In the Battle of Champaubert on 10 February 1814, Marmont's corps led the attack, but Ney's corps became involved in the fighting after 11:00 am. At the Battle of Montmirail the next day, Meunier's division was engaged in a bitter struggle against the Russians at the village of Marchais-en-Brie. On 12 February, the 1st Young Guard Division joined in the pursuit of the Allies in the Battle of Château-Thierry. At the Battle of Vauchamps two days later, Ney's corps was present but not engaged.
