What if the battle is played out differently? I don't own any of the characters except for the four special people which will be introduced in the next chapter .The credit goes to J.K. Rowlings.

Hogwarts School For Witches and Wizards:

Everything is a blur. With many coloured spells being cast back and forth between Professor McGonagall and Professor Snape. Every student, including Harry and the Order watch them dueling with each other with such a ferocity it makes it hard to find out where McGonagall and Snape are.

After more than a few minutes of dueling with many awesome displays of spells and charms, Professor Snape deflects spells cast from McGonagall and has silently been directing the spells to the new Dark Arts teacher and Muggle Studies teacher. Amycus and Alecto Carrow respectively, while they are rushing to his aid. The spells have struck them hard and they have collapsed to the floor groaning. Following this, Professor Snape tries to transform while escaping from Professor McGonagall's fury, with spells being cast in his direction. He has managed to succeed, escaping by jumping out of the glass panels of the Great Hall.

"COWARD!" Professor McGonagall screams in anger when she sees Professor Snape is out of her range of spells. She starts to cast flame charms all over the Great Hall to warm the students up while they are cheering over the dismissal of Professor Snape.

Suddenly Hogwarts quickly darkens, their happiness quickly fades away, as they hear the voice of Lord Voldemort whispering in their ears. It is telling them they have one hour to hand in Harry Potter or the school will be attacked. Many students start to panic, cry or scream in fear when they hear Voldemort's announcement. When Voldemort finishes speaking, everyone begins to stare at Harry.

Pansy Parkinson from the Slytherin House starts to yell at everyone to grab him to prevent Voldemort from attacking the school. However, Professor McGonagall and the rest of the students start to defend Harry and ask Mr. Filch the caretaker to lead the Slytherin House to the dungeons .

"I do hope that you have a good reason for coming here Potter" said McGonagall.

Harry replies "I'm acting on Dumbledore's orders. I need time, as much as you can give me. Evacuate as many students as you can through the Room of Requirement on the seventh floor. I do not wish anyone to die for me at all"

McGonagall nods to him and says "Do what you have to do Potter. We will secure the castle."

Watching Harry, Ron and Hermione leave the great hall, McGonagall hurries forward to the Order of Phoenix group whose members are creating battle plans for the defence of Hogwarts from the invasion of Voldemort's forces. Madam Pince the librarian and Madam Pomfrey are instructed to evacuate students who are underage or want to be out of the crossfire.

Overhearing the conversation while hurrying towards them, McGonagall hears Lupin say "Arthur and I will take a few fighters and defend from the grounds. The teachers will activate every single defence of Hogwarts while Kingsley, Bill and Charlie will take some fighters and shoot spells from the Astronomy, Gryffindor and Ravenclaw towers at a range."

One of the unknown members asks "But what about the secret passages and corridors?"

"Leave that to us. No one gets there faster than us " Fred and George, the Weasley twins answer.

"Okay, I totally agree with the twins on this due to the fact that they can travel fast all over Hogwarts. Does anyone have any more questions?" Kingsley asks.

"I have something to share." answers McGonagall "Dumbledore and I have been developing this spell which might be extremely useful to our cause. However it has never been tested at all. I will need some time to cast the spell but someone will need to cover me while I'm casting it."

Kingsley frowns and replies "That's unfortunate but we really do not have anyone to spare at the moment except for Molly Weasley. Minerva, much as I hate to say this but we don't have much choice. It is a risk worth taking but only cast the spell after activating all defences. Molly, your second task will be to protect Minerva when the Defence spells are totally activated which means you, Flitwick and Slughorn will create an extremely strong shield over Hogwarts."

Molly replies "Of course. I will do my best" then turning to face McGonagall saying "Don't worry my dear. I will not let them get you as long as I am around"

Minerva smiles in reply.
