An unexpected Assault

The last rays of sunlight painted the Hogwarts grounds in a warm glow as the students packed up their belongings, chatting excitedly about the upcoming summer. Harry stood by the Slytherin common room entrance, arms crossed, watching the second through seventh-year students he had trained over the years preparing themselves for a possible battle.

"You think they'll come today?" Daphne asked, leaning against the wall next to him, her voice steady but tinged with concern.

Harry glanced at her, his emerald eyes calm. "I can feel it. Voldemort's been too quiet. This isn't peace; it's the silence before the storm."

Hermione joined them, adjusting her wand holster. "We're ready. We've trained for this."

Tracey, standing nearby, smirked. "And if anyone doubts us, we'll remind them why Slytherin is the house of cunning, resourcefulness, and power."

As night descended, the alarms of Hogwarts rang out, sending students scrambling to their positions. Outside the castle, a dark force emerged from the Forbidden Forest: Death Eaters, dark creatures like trolls, giants, and even subjugated centaurs, marched toward the castle. Above them, Dementors swirled ominously.

The barrier protecting Hogwarts shimmered as Voldemort's forces launched their first assault. The wards strained and groaned before finally shattering with an explosive crack that echoed across the grounds.

"They're here," Harry said, his voice calm but commanding. "You know your roles. Let's show them what Slytherins are made of."

The students sprang into action, their training evident in their precision and confidence. The fifth years and older from other houses joined in, and soon the castle grounds became a battlefield.

Harry strode out to the center of the chaos, his presence immediately commanding attention. Raising his wand, he cast a series of powerful spells that tore through the enemy ranks.

A group of Death Eaters charged him, but with a wave of his hand, he unleashed a concussive wave of energy, sending them sprawling. A troll raised its club to strike, but Harry Apparated to its shoulder, plunged his wand into its neck, and cast a fiery explosion that felled the beast instantly.

His movements were precise, efficient, and devastating. He summoned walls of fire to trap groups of enemies, used water to sweep them away, and conjured massive gusts of wind to disarm and disorient. Every action was calculated, every spell a masterpiece of control and destruction.

The students he had trained followed suit, moving as a coordinated unit. While the professors held back, watching in awe, the students dismantled the Death Eaters with a combination of skill, teamwork, and ingenuity.

McGonagall, standing on the castle steps, whispered, "It's... remarkable. They don't even need us."

Snape, watching with a rare look of pride, added, "This is what happens when you teach them not just to pass exams but to fight for survival."

As the battlefield erupted into chaos, two figures stepped into the fray. Dumbledore, his robes billowing, approached Voldemort, his expression calm but his eyes alight with anticipation.

Voldemort sneered. "Albus. Finally ready to face me without your naive ideals?"

Dumbledore smiled faintly. "Oh, I haven't abandoned my ideals, Tom. I've merely adapted to the reality you've created."

Voldemort's eyes glinted with dark amusement. "Then let's settle this, once and for all."

The air between them grew heavy with magic as the first spells were fired. Voldemort unleashed a torrent of curses, each one more deadly than the last, but Dumbledore countered with a dazzling display of defensive magic. Their duel was a clash of titans, each spell rocking the battlefield and drawing the attention of everyone present.

Harry, standing on the sidelines after finishing his part of the battle, watched with interest. He noted how Dumbledore's movements had become sharper, more aggressive, a clear result of their countless sparring sessions.

"They're holding nothing back," Daphne said, joining him.

"They can't afford to," Harry replied, his gaze never leaving the fight.

The duel raged on, with Voldemort and Dumbledore exchanging chains of spells that illuminated the night sky. Fire, ice, lightning, and raw energy crackled as the two wizards pushed each other to their limits.

As Harry observed the battle, he couldn't help but feel a sense of satisfaction. The students he had trained were holding their own, the professors were impressed, and even Voldemort had been forced to acknowledge the strength of Hogwarts' defenders.

Hermione joined him, her face alight with a mixture of pride and concern. "We've come so far, haven't we?"

Harry nodded. "And we're not done yet. This is just the beginning."

While Dumbledore and Voldemort's duel reached new heights of intensity, the students and remaining Death Eaters clashed across the grounds. The defenders of Hogwarts, inspired by Harry's leadership and example, fought with a ferocity that would be remembered for generations.

The night was far from over, but the tide of the battle had already begun to turn.
