"'You will give the order to remove Dolores Umbridge from Hogwarts,' said Dumbledore [to Cornelius Fudge]. 'You will tell your Aurors to stop searching for my Care of Magical Creatures teacher so that he can return to work. I will give you . . .' Dumbledore pulled a watch with twelve hands from his pocket and surveyed it, 'half an hour of my time tonight, in which I think we shall be more than able to cover the important points of what has happened here. After that, I shall need to return to my school.'" (pg 818 OotP,am.hc.v.)

"Voldemort raised his wand and sent another jet of green light at Dumbledore, who turned and was gone in a whirling of his cloak; next second he had reappeared behind Voldemort and waved his wand toward the remnants of the fountain; the other statues sprang to life too. The statue of the witch ran at Bellatrix, who screamed and sent spells streaming uselessly off its chest, before it dived at her, pinning her to the floor. Meanwhile the goblin and the house-elf scuttled toward the fireplaces set along the wall, and the one-armed centaur galloped at Voldemort, who vanished and reappeared beside the pool. The headless statue thrust Harry backward, away from the fight, as Dumbledore advanced on Voldemort and the golden centaur cantered around them both." (pg 813)
