 For the 1867 version two additional characters, men-at-arms were added to Act 2 and given a comic duet, in English-speaking countries widely known as the "Gendarmes' Duet" or the "bold gendarmes", from H. B. Farnie's English adaptation.As well as being a popular performance piece, it formed the basis for the U.S. "Marines' Hymn".The two-act French libretto was written by Louis-Adolphe Jaime and Étienne Tréfeu, and the opera was first staged at the Théâtre des Bouffes-Parisiens, Paris, on 19 November 1859.
