On 15 August 1792, the 12th Chasseurs à Cheval Regiment was reviewed at Sedan by Gilbert du Motier, Marquis de Lafayette, who fled to the Austrians a few days later after being accused of treason.
After Valmy, the 12th Chasseurs à Cheval went north as part of the Army of Belgium under Pierre de Ruel, marquis de Beurnonville.
