Hickory was one of the rabbits who were liberated from Cowslip's warren by the Watership Down rabbits. He and several other rabbits including his mate Marigold, decided to live inside Primrose's old home of Redstone. They lived peaceful lives until Woundwort and Vervain (under the alias of Wheatstalk and Chaff respectively), arrived there to try and turn Redstone into a warren controlled by force and not reason. At first Hickory was taken in by Woundwort's guise and it wasn't until it was too late that he found out the truth. Thanks to a bargain he made with Cowslip, who wanted revenge on his deserters, Woundwort tricked Hickory and the others rabbits at Redstone to stay put while their warren gets demolished by man, but Hazel and the others saved them in time. Hickory was re-united with Marigold and they all now live with Hazel and the others on Watership Down.
