Veillons au salut de l'Empire () was the unofficial French national anthem under Napoleon.
The lyrics were written in the later months of 1791 by Adrien-Simon Boy, who was the chief surgeon of the Army of the Rhine. Boy would only have written the first three verses, as the fourth would be added in 1810 by an unknown author.
The song's melody was from Vous qui dâÂÂamoureuse aventure, courez et plaisirs et dangers of the comedic opera Renaud d'Ast (1787) by Nicolas Dalayrac.
