 This idea remained in the notes after the writing of chapter eleven, but after chapter twelve was complete, Tolkien wrote "Dragon killed in the Battle of the Lake" in the margin of his notes.Bard appears during the drafting for chapter thirteen, when it is said that he kills the dragon with his ancestor Girion's favourite Black Arrow.Tolkien's keeping Bard alive for the rest of the story significantly complicates it since, as the heir of Girion, Bard gives the inhabitants of Lake-town a legitimate claim to Smaug's treasure.
