Quote from : Harry Potter and the Deathly Hallows: Part 2 Movie

Lord Voldemort: [as Harry, Ron and Hermione stand in the boathouse, Voldemort's voice echoes throughout the castle grounds] You have fought valiantly, but in vain.
[Shot of a female Death Eater disarming George Weasley]
Lord Voldemort: I do not wish this. Every drop of magical blood spilled is a terrible waste. I therefore command my forces to retreat.
[Shot of all Death Eaters lowering their wands]
Lord Voldemort: In their absence, dispose of your dead with dignity. Harry Potter, I now speak directly to you. On this night, you have allowed your friends to die for you rather than face me yourself.
[Harry stares at the burning wreckage of Hogwarts]
Lord Voldemort: There is no greater dishonor. Join me in the Forbidden Forest and confront your fate. If you do not do this, I shall kill every last man, woman and child who tries to conceal you from me.
