This is a fictional story of a Kentucky Thoroughbred loaned to the Pony Express by a Kentucky breeder with great reluctance and sorrow. Thunderfoot was the horse of his dreams. His love for his country was the only force powerful enough to make him let go of this horse, and he wanted him back when his tour with the Pony Express was over.
In this short story Thunderfoot proves his greatness as he encounters flooded rivers, Indian attacks, and other adversities before he returns to Kentucky.
