Black Fury #41

This is an anthology issue containing two stories. The main story, "Nightmare," features Black Fury, a legendary wild stallion, who is given a magical herb by a señor that grants him the power to control his master's actions. A villain seeks to use this power to make Black Fury obey his commands. The second story, "The Wonder Horse in Break or Die," tells of a cruel man who mistreats his neighbors and hoards resources; Black Fury fearlessly rescues a foal from a quicksand and becomes captured, but eventually breaks free and leads a group of wild horses that were bred from Arabian stock to establish Indian cavalry, preventing the Comanches from conquering the territory.
