At this point, everyone else in the room had drawn their wands and began casting spells and hexes at one another. Hermione made her way around the outside of the office, her own wand aimed at the Death Eater nearest her. She cast Levicorpus, hanging him upside down immediately, and left him in the air as she bound him with ropes. Both Harry and Snape had also managed to stun, bind and knock the other three Death Eaters unconscious before Dumbledore withdrew from his battle with Voldemort momentarily, casting a shield around all of them.
