Napoleon formed his own Mamluk corps, the last known Mamluk force, in the early years of the 19th century, and used Mamluks in a number of his campaigns. Even his Imperial Guard had Mamluk soldiers during the Belgian campaign, including one of his personal servants. Napoleon's famous bodyguard Roustam Raza was a Mamluk who had been sold in Egypt.
Throughout the Napoleonic era there was a special Mamluk corps in the French army. In his history of the 13th Chasseurs Colonel Descaves recounts how Napoleon used the Mamluks in Egypt. In the so-called "Instructions" that Bonaparte gave to Kleber after departure, Napoleon wrote that he had already bought from Syrian merchants about 2,000 Mamluks with whom he intended to form a special detachment.
Roustam was born in Tbilisi, Georgia to Armenian parents. At thirteen Roustan was kidnapped and sold as a slave in Cairo. The Turks gave him the name Idzhahia. The sheikh of Cairo presented him to General Napoleon Bonaparte in 1798. Roustam served as a bodyguard of Napoleon until 1814, when he married Mademoiselle Douville in Dourdan, France and refused to follow the Emperor in his exile to Elba.On 7 December 1845, Roustam died in Dourdan.
