The story is told in the form of a picaresque or episodic quest; several chapters introduce a new type of monster or threat as Bilbo progresses through the landscape. Bilbo gains a new level of maturi ..... ty, competence, and wisdom by accepting the disreputable, romantic, fey, and adventurous sides of his nature and applying his wits and common sense. The story reaches its climax in the Battle of Five Armies, where many of the characters and creatures from earlier chapters re-emerge to engage in conflict. Personal growth and forms of heroism are central themes of the story, along with motifs of warfare. These themes have led critics to view Tolkien's own experiences during World War I as instrumental in shaping the story. The author's scholarly knowledge of Germanic philology and interest in mythology and fairy tales are often noted as influences, but more recent fiction including adventure stories and the works of William Morris also played a part.
