Harry Stuns Umbridge and Corban Yaxley

PAGES: 261-263

Enraged by Umbridge's lies and cruelty, Harry casts a Stunning Spell, knocking out both Umbridge and Corban Yaxley. With the protective Patronus cat gone, Dementors approach Mary Cattermole. Harry casts his Patronus, driving the Dementors away, while Hermione quickly duplicates the Horcrux locket to replace the real one. They release Mary Cattermole from her chains and prepare to escape the Ministry with her.
