Battle of Hogwarts

May 1-2, 1998
The climactic final showdown between the side of good and the side of evil. Hogwarts Castle was damaged in this battle and fifty people died defending it, including Fred Weasley, Tonks, Remus Lupin, and Colin Creevey. The Death Eaters enlisted giants, Dementors, and Acromantulas to fight for them, while the defenders of Hogwarts included centaurs, house-elves, students and their parents, shopkeepers from Hogsmeade, enchanted armour, statues and desks, and many others. In the end, Lord Voldemort was killed in the Great Hall when his Killing Curse rebounded and hit him (DH31, DH32, DH33, DH34, DH35, DH36).
