As the war of secession continues, on the side of Fort Bow, Colonel Appeltown waits for reinforcements. A named Cochran has launched a rumor that he would have found gold in the hills. This risks to row all the gold seekers, bandits, cheaters and others in the area. Moreover, it would have to cross Indian territory with which peace can be broken at any moment. But it is especially the reaction of Chief Loup Gris who worries The Colonel. And the only reinforcements on which he can count are the survivors of Captain Stark's famous 22nd cavalry: Sergeant Cornélius Chesterfield and Corporal Blutch. They will have to try everything to avoid an Indian war, even set up a marriage at Fort Bow.
