In the series finale, attention turns to escorting the Death Eaters' main target, Harry Potter, from his summer home with the Dursleys to the Weasleys' Burrow. Later in the novel, after Voldemort's takeover of the Ministry had succeeded, some Order members hosted ""Potterwatch"", a secret pirate radio programme providing news on the Wizarding World that Voldemort's regime did not want the general population to know. During the climax of the book, most of the Order, aided by Dumbledore's Army, the Hogwarts staff and the older students, Slytherin house members included, fought against the Death Eaters in the Battle of Hogwarts, in which several Order members and other allies lost their lives.
