On 23 December 1854 a fourth regiment was created, the Zouaves of the Imperial Guard. The actual formation of this unit was delayed until 15 March 1855 when detachments from the zouave regiments already serving in the Crimea were brought together before Sebastopol for this purpose. Having earned the unusual distinction of being created on the field of battle, the Zouaves of the Imperial Guard served through the remainder of the Crimean War and subsequently in all the campaigns of the Second Empire. Their peace-time garrisons were initially at Saint-Cloud and then Versailles from 1857. This regiment wore the classic zouave uniform but with yellow braiding and piping substituted for the red of the line regiments.
