Lawrence, Kansas, August 21, 1863... The pro-sudist guerrillas commanded by William Clarke Quantrill are about to attack the city. After a short battle that left no chance for the few black northern soldiers who guarded the city, Quantrill's troops began to ruin the city. While they were looting everything, they were interrupted by the arrival of Stark and his cavalry. Quantrill ordered his soldiers to flee as soon as possible but in the adventure, Frank James, one of his right arms, was captured by Blutch... This unexpected capture gave the idea of a mission to General Alexander: Locking Chesterfield with James and organizing their escape, while hoping that he would lead them to Quantrill... With Blutch's complicity, of course...
