Les Tuniques Bleues (Dutch: De Blauwbloezen) is a Belgian series of bandes dessinées (comic books in the Franco-Belgian tradition), first published in Spirou magazine and later collected in albums by Dupuis. Created by artist Louis Salverius and writer Raoul Cauvin, the series was taken up by artist Willy Lambillotte after Salverius' death. It follows two United States cavalrymen through a series of battles and adventures. The first album of the series was published in 1970. The series' name, Les Tuniques Bleues, literally "the bluecoats", refers to the Northern (union) army during the American Civil War. One English edition of the comic was published in 2004 as "The Blue Tunics: The Blues in Black and White" by Reney Editions. Since then Publisher Cinebook has started to print the comics
