* NoExportForYou/KeepCirculatingTheTapes: Luckily for Anglophone fans, most of the series has been translated, with different albums translated by Methuen, [[Creator/MarvelComics Epic]] and Dargaud. However, [[MissingEpisode the fifth album of the original Fort Navajo arc]] - the climax of the Apache war - was never translated, and the five most recent volumes, written by [[Creator/{{Moebius}} Giraud]] after Charlier's death, are also untranslated. The English volumes are also very difficult to find and have been out-of-print since at least the 90s.
* TheCameo: Corporal Blutch and Sergeant Chesterfield of Comicbook/LesTuniquesBleues make an appearance in one album.
