Captain Broom was the former captain of the Redstone Owsla. When Primrose, now free from Efrafa, returns to see her old friends Broom informs her that an unspecified illness has wiped out the entire warren but him. He joins the Watership Down rabbits at Hazel's invitation. He usually bores them with his tall tales, but does have wisdom (his knowledge about sheep helps avert a disaster) and can be relied upon in a crisis. He and Captain Holly also get along with each other.
