On his return from mission, Blutch discovers that Arabesque, his precious mare able to make the death during the charges, has been requisitioned by another northernist unit! Ivre de rage, he destroys everything in his passage, including the officers' mess, but manages to convince Chesterfield to go in search of his horse. A dangerous and hilarious road movie awaits the famous duo, during which they will shed light on the dreads of the Civil War, meet an old enemy, miss repeatedly... and make their readers laugh! An album to be enjoyed especially, since Lambil is more remarkable than ever in the art of drawing equidae. But also because it will be the latest Blue Tunics written by Raoul Cauvin, after 64 albums entered the history of comics!
