Blutch finally found a way to leave the army? During a charge, Blutch, who is connected to Sergeant Chesterfield, is unconquered by a shell. This shell is found completely hebated. All the sergeant's attempts to restore his memory are futile. Blutch has therefore been allowed to return to his homes. On the train, on the way back, a liberable wounded person evokes Arabesque, the Blutch horse that would now have been mounted by Stark! Blutch disappears and finds himself in the Confederate camp. His solitary charge intended to save his horse will be interpreted as a heroic act by his hierarchy. In addition his decoration for the medal of merit will be a camouflet for Sergeant Chesterfield. Blutch amnesic, was it bluff? Everyone will make his opinion...
