Chapter 31：The Battle of Hogwarts

In which McGonagall orders the evacuation of those underage or who do not wish to fight, Voldemort delivers an ultimatum, and Harry learns how Voldemort acquired the diadem. Ron and Hermione return from destroying the cup, and together Harry, Ron and Hermione go to the Room of Requirement to destroy the diadem. There they encounter Draco Malfoy, Crabbe, and Goyle, but his former henchmen no longer answer to Draco; during the subsequent duel, Crabbe unleashes Fiendfyre, which destroys much of the room’s contents and kills him. Harry, Ron and Hermione escape, rescuing Draco and Goyle in the process. They then encounter Percy and Fred, duelling Death Eaters, only to be caught by an explosion that kills Fred.
