Hidden beneath the Invisibility Cloak

Hidden beneath the Invisibility Cloak, Harry cast a Shield Charm between Neville and Voldemort before the latter could raise his stamps of the battling giants, Hagrid’s yell came loudest of all.

“HARRY!” Hagrid shouted. “HARRY – WHERE’S HARRY?” Chaos reigned. The charging centaurs were scattering the Death Eaters, everyone was feeling the giants’ stamping feet, and nearer and nearer thundered the reinforcements that had come from who knew where; Harry saw great winged creatures soaring the heads of Voldemort’s giants, thestrals and Buckbeak the hippogriff scratching at their eyes while Grawp punched and pummeled them and now the wizards, defenders of Hogwarts and Death Eaters alike were being forced back into the castle. Harry was shooting jinxes and curses at any Death Eater he could see, and they crumpled, not knowing what or who had hit them, and their bodies were trampled by the retreating crowd. Still hidden beneath the Invisibility Cloak, Harry was buffered into the entrance hall: He was searching for Voldemort and saw him across the room, firing spells from his wand as he backed into the Great Hall, still screaming instructions to his followers as he sent curses flying left and right; Harry cast more Shield Charms, and Voldemort’s would-be victims. Seamus Finnigan and Hannah Abbott, darted past him into the Great Hall, where they joined the fight already flourishing inside it.

And now there were more, even more people storming up the front steps, and Harry saw Charlie Weasley overtaking Horace Slughorn, who was still wearing his emerald pajamas. They seemed to have returned at the head of what looked like the families and friends of every Hogwarts student who had remained to fight along with the shopkeeps and homeowners of Hogsmeade. The centaurs Bane, Ronan and Magorian burst into the hall with a great clatter of hooves, as behind Harry the door that led to the kitchens was blasted off its hinges.

The house-elves of Hogwarts swarmed into the entrance hall, screaming and waving carving knives and cleaver, and at their head, the locker of Regulus Black bouncing on his chest, was Kreacher, his bullfrog’s voice audible even above this din: “Fight! Fight! Fight for my Master, defender of house-elves! Fight the Dark Lord, in the name of brave Regulus! Fight!”

They were hacking and stabbing at the ankles and shim of Death Eaters their tiny faces alive with malice, and everywhere Harry looked Death Eaters were folding under sheer weight of numbers, overcome by spells, dragging arrows from wounds, stabbed in the leg by elves, or else simply attempting to escape, but swallowed by the oncoming horde.

But it was not over yet: Harry sped between duelers, past a struggling prisoners, and into he Great Hall.

Voldemort was in the center of the battle, and he was striking and smiting al within reach. Harry could not get a clear shot, but fought his way nearer, still invisible, and the Great Hall became more and more crowded as everyone who could walk forced their way inside.
