This novelette is the sixth in the series known as "The Laramie Saga". Rather than at Laramie, this story takes place mainly on the trail and at the Lakota Sioux Reservation in the Black Hills. Texas Long Horns are driven to the starving Lakota Sioux and the cavalry men at Fort Laramie attempt to divert the herd for the army's use. Mato, step son of James Riley helps resolve the situation. Although this is a sequel to "The Z-Bar Ranch Incident" it stands by itself very well. It is a fast moving western adventure story.
