Battle of Hogwarts

First Half of the Battle

Kingsley Shacklebolt: "We've only got half an hour until midnight, so we need to act fast! A battle plan has been agreed between the teachers of Hogwarts and the Order of the Phoenix. Professors Flitwick, Sprout and McGonagall are going to take groups of fighters up to the three highest Towers – Ravenclaw, Astronomy and Gryffindor – where they'll have a good overview, excellent positions from which to work spells. Meanwhile, Remus, Arthur, and I will take groups into the grounds. We'll need somebody to organise defence of the entrances of the passageways into the school –"Fred Weasley: "sounds like a job for us."Kingsley Shacklebolt: "All right, leaders up here and we'll divide up the troops!"— commanding the defence of Hogwarts.

Although all those underaged were to be evacuated, four known students, , and , both of whom aged 16, , who was either 14 or 15, and , who was either 13 or 14, stayed and fought, due to being members of Dumbledore's Army.

As the defenders of Hogwarts prepared to hold off Voldemort so that Harry could finish his search for the object of Ravenclaw's, the launched attacks on the castle but were kept from entering. The Hogwarts defenders were able to fend off the Death Eaters using an array of tactics: and Neville planned to use dangerous plants from the greenhouses against the Death Eaters, such as lobbying over the walls, , and pods, as well as the bewitched suits of armour and wand duels. The whole castle shook with the force of the Death Eaters' sinister enchantments, and Harry met up with and , his boarhound , and his giant half-brother, , as they joined in defending the castle against Death Eaters.
