(A/N: Consider that Tom Riddle "left" the Muggle world around 1945 or so and has spent his time in the Wizarding World ever since. Therefore, he has no real idea what Muggles are capable of as technology has advanced over the last 50 years. Here's a small series of "endings" for Tom. They all have the same set up at the beginning. Assume this first part is attached to all the endings. Also please assume Horcruxes don't exist or they have all been taken care of. This happens during sixth year, maybe?
Reminder, chapters in this story series are not beta'd. Read at your own risk! ;-)
Also, my apologies to those "experts" out there who know a lot more about this tech than what I gleaned from the few minutes I used to look it up on Google. I had a fun idea and ran with it, content not to little things like facts get in my way. :) Please understand this was written with fun in mind, not accuracy. :)
New Technology
Harry, Ron, and Hermione landed and for once did not fall over as they Portkeyed to her parents' house. Professor Dumbledore had been kind enough to help them get there, but with the understanding they would not stay for more than a few hours and they would stay indoors where they could not be observed from the road in front of the Grangers' house.
Harry watched Hermione greet her parents with a suppressed smile, wishing he could experience this with his parents. He was cordial when they turned to him. Ron acted like a deer caught in the headlights; Harry almost laughed at his friend.
The five of them sat in the living room and talked for a while, with the three Grangers doing most of the talking. Harry did his best to follow along and support his friend as she tried to talk her parents into leaving the country for a year.
"Hey, mate," Ron whispered and bumped Harry's elbow with his as the pleas and discussion started to repeat. "Do you really believe this is true? This sounds like fiction to me."
Harry looked over at the magazine that Ron had in his hand, a news periodical he had picked up off the low table in front of them. The open article was about new advances in war technology and how it outstripped the old technology of even ten years earlier. Knowing this was a current news periodical, he whispered back, "Yeah, it's all real."
"Blimey, too bad we can't get some." Ron dropped the magazine back onto the table.
Too bad, Harry thought as the tuned back into the other conversation, but that thought would not leave him. Harry knew the prophecy. He knew what was in store for the world if he should fail. The Muggles would suffer too. It really was too bad they could not round all the Death Eaters up in one place and then "snuff them" with one of the technologies mentioned in the article he had looked at.
Those thoughts circled in his head for the rest of the time he was there. Just before they were about to leave, Harry had an idea. Turning to Mr Granger, he said, "Do you mind if I take this magazine with us?"
"Help yourself," Granger told him. "We'll get the new one in a day or two and we've already read that one."
"Thanks," Harry said with a satisfied smile as he folded it lengthwise and stuck it in a back pocket. They left a few minutes later.
That evening, Harry sat in front of the fire in the Gryffindor Tower and studied the article on war technology very closely. He was not concerned about the latest and greatest since it was all electronic in some way and therefore would not work in a heavy magical environment, but he was thinking very hard about what it was replacing. How hard would it be get a hold of that? Sirius had left him some money if that was needed, and surely Dumbledore had contacts within the Muggle government, or else he would bet Amelia Bones did.
Hermione came and sat down next to him with her Arithmancy book in hand. "What are you looking at, Harry?"
At the moment, Harry was actually pleased that his dorm mate was off searching for a snack in the kitchens. He really did not want an argument between his two best friends, but he did want Hermione's honest opinion on something.
"Hermione, have you ever considered that Riddle finished Hogwarts around the time of the end of World War 2, entered the Wizarding World, and never looked back?"
"No I haven't, why?"
Harry put the magazine in front of her. "The world has changed a lot in fifty years. He knows nothing of the new technology."
The girl frowned. "Harry, the Wizarding World doesn't do stuff like this. It's not accepted."
"So, are we're going to be so prideful that we'll let ourselves get killed because we don't want to pick up a gun, touch explosives, or take whatever advantage we can get?"
"That is the mindset," she said a little sadly. "Plus, that stuff wouldn't work for us. It's all highly integrated with electronics, and that doesn't work around magic."
He grinned a knowing grin. "That would be true for the stuff here, but what about the stuff that's ten or twenty years old and is being replaced? A lot of it is mechanical, but it's still way more advanced than what Riddle knows about and can deal with." He shared "his weapon idea" with her.
"So all we have to do is put up a thick rock wall, preferably with a steel plate too, around Hogwarts, say twenty feet high and ten feet thick about thirty feet from the castle walls, get Riddle and his merry band of minions here, then unleash the weapon and war over," he outlined.
Hermione actually snorted. "That all well and good … assuming," she disbelievingly emphasized, "you can get a hold of that and that Dumbledore lets you do that."
Harry considered that for a long moment and Hermione watched him with interest, waiting to see what he would come up with to solve the apparently insurmountable problems.
After a moment, he grinned again. "I think I can solve both of those with a little Slytherin ingenuity."
"Slytherin ingenuity?" Hermione asked with confusion, wonder what that meant.
"You probably know it as blackmail," Harry said as he got up and walked out of the common room, while Hermione sat there and gaped.
Harry went to the Hufflepuff entrance and knocked loudly several times on the door. It took a few minutes, but a young second year female Puff finally answered and almost squeaked when she saw who it was. "I need to talk to Susan Bones … please. It's urgent."
The girl grinned and turned red as she nodded and then scampered back inside.
A few minutes later, the door opened again and a slightly flushed Susan Bones came out. "Hi Harry," she said little breathlessly as she stared into his eyes. "What can I help you with?"
Harry might have seen how Susan was acting, but he was oblivious to what it meant. "Hey, I need a really big favor. I need to talk to your aunt as soon as possible. Tell her it's about ending the war as soon as possible. Can you please help me get her that message?"
Susan drooped slightly, looking disappointed for a few seconds. Then she perked back up and a smile came over her. "I think I can if you could help me with a small something. But perhaps you should tell me what you want to talk to Auntie about. She might need to do something before she comes to talk to you."
He looked thoughtful for a moment. "No, I don't think so. I just need her to talk to some of the Muggle government leaders about getting me or us something. I figured she would have the right contact to start at the top so this happens faster."
She nodded. "She does work with the Muggle government from time to time."
"Splendid! So, what favor did you need?" Harry asked sincerely, not really thinking about why Susan's expression seemed to be constantly changing between shyness and determination.
"Oh, I think about five minutes of your time should do," she said coyly.
"Sure, we can do it later during the holidays, or I have five minutes now, if that would be better."
"Lovely," Susan said with a big grin and with a determined look, closed the gap between them.
Before Harry knew what was happening, Susan had grabbed the front of his robes and pushed him against the wall before pushing herself against him. It took him only two seconds to realize what favor she wanted. Two seconds to realize kissing Susan was nothing like kissing Cho. He slowly put his arms around her and did his best to endure the "manhandling". It was amazing what he had to do for the war effort.
Eight minutes later, Susan whispered into his ear, "Expect Auntie to show up tomorrow." She smoothed the front of his robes for him. "And Harry, there's more where that came from if you want it, all backed by Hufflepuff loyalty." She winked as she turned and walked back into the Hufflepuff common room.
Harry stood there for a moment, still catching his breath, glad that it was the Yule holidays and no one had walked by. With a goofy grin and a new spring in his step, he finally started moving down the corridor, his mind on the strawberry blonde that had just left him. She was attractive and they had interacted well together in the DA last year. Thoughts about all other girls were nowhere to be found at the moment.
Despite the slight daze he was in, he made it to Dumbledore's office and gave the password to get up the stairs. At the door to the actual office, he knocked and heard "Enter". Taking a deep breath and vowing to follow his Slytherin instincts, he walked in. Inside, he saw Dumbledore behind his desk, working on paperwork.
"Harry, is something the wrong? Another vision perhaps?"
"No, sir. I had an idea I wanted to run by you." Harry spend the next five minutes giving an overview of his plan. He was not pleased to see the Headmaster's expression grow dark as he finished up.
"While that it is an admirable idea to end the war quickly to prevent loss of innocent life, I'm afraid I can not condone your weapon idea. I simply can not let you do this," Dumbledore told him with a heavy heart.
Harry was afraid of an answer like that, so he pulled out his trump card. "Sir, I don't think you understand. You've said this is my war; that I have to end it…"
"Yes, Harry," the Headmaster cut him off. "You have to end it, but you will need me and others to get to that point. The Wizarding World will not accept your weapon."
That chaffed him and gave him more determination. "Headmaster, it's you who doesn't understand. The weapon exists whether the Wizarding World wants to accept it or not. All I'm asking for is your help to prepare the defenses here at the school so no one but Riddle's side gets hurt. I will arrange for the weapon and I will get Riddle here," Harry said emphatically.
"Harry…"
"Professor Dumbledore! I am not asking for permission, I'm telling you this is how the war will end. It's this way or the highway for me." Harry stared at the old man, practically daring him to use Legilimency to determine how serious he was.
"You would leave and condemn us all?" Dumbledore asked with incredulity.
Harry leaned forward. "There are seven billion Muggles in over one hundred different countries and I'd have magic to help me hide, as well as those I decided to take with me. All I'm asking from you is three things. One, I need your help, and probably Professor McGonagall's too, to create a protective barrier around the school. Two, I need you to mock Tom for a few minutes when he gets here so all of his forces assembles together and that will also give me a moment to set my sights on him. And three, I need you to otherwise stay out of the way for everything else." He waved his hand as if batting a fly away. "I'm sure there will be a few other small things like getting Hagrid to move into the castle at the right time so he doesn't get hurt, but I will take care of or direct the rest. I'll be speaking to Madam Bones tomorrow about getting the weapon from the Muggles."
Dumbledore sighed and fell back in his chair. "While you probably do know more about the current Muggle world than I, I'm still quite sure the Muggle government will not get involved."
"Please let me worry about that, Professor. There is a chance you're right; however, I'm sure the unexplained disasters we've had lately that some are blaming on terrorists will help to convince them. If not, I'm sure magic can help the weapons disappear for a week or so while we borrow them," Harry said with a smile.
"Harry! You can't steal things from the Muggles! That would cause them to find out about us…"
"I said borrow, Professor. Now, do we have a deal? And that includes not telling Professor Snape until I say it's time." Harry watched the old man struggle with the question. There really was no guessing about the outcome, as the alternative was unthinkable. In reality, he would not totally disappear if Dumbledore said no, but he would wage war much differently than the Headmaster had planned.
With a sad sigh, Dumbledore finally nodded. "Very well, Harry. I do suppose it is your war. I just hope you know what you're getting yourself into."
Harry gave him a cheeky grin. "Probably not, Professor, but I do know what I'm getting myself out of, and that's a stupid prophecy. Cheers!"
Feeling good about it all, Harry returned to Gryffindor Tower planning and scheming along the way.
The next day at lunch, a slightly pink faced Susan Bones came up behind Harry. She placed her left hand on his left shoulder and leaned over to whisper into his right ear. "Auntie is here to talk to you."
He turned to look at her and found her face "right there". With a smile, he said, "Want to come with me?"
Her smile somehow grew. "I'd love to."
He got up and she hooked her arm around his and let him escort her out of the Great Hall, both of them missing a glare from another girl behind them.
Quietly, he said, "You do realize you'll have to keep all of this to yourself, no telling anyone?"
"I'm a Hufflepuff, Harry. I will support you and keep your secrets no matter what, I promise," she said very seriously.
"I hope you're not tested on that," he said, truly hoping Malfoy and his ilk left her alone.
They walked into the Entrance Hall to find Amelia Bones waiting on them. She raised an eyebrow at the two walking arm and arm. Susan returned a smug look.
"Mr Potter."
"Madam Bones, thank you for coming. Could we find a room for some privacy?"
The three found a room and Amelia put up the necessary privacy charms. "Mr Potter, my niece said you had an idea on how to end the war quickly. If I can save the lives of my Aurors and innocent civilians, I'm very willing to listen -- especially to the 'Chosen One'." She ended with a smile to let him know she did not take the title the Daily Prophet had given him completely seriously.
Harry grinned a little nervously and did his best to ignore the not so hidden question. "Madam Bones, I have an idea and I've already secured the Headmaster's agreement to cooperate here at Hogwarts, so I believe that's half battle. The other half is my need to acquire something from the Muggles." He spent the next ten minutes explaining his idea.
The woman sat there and attentively listened, not showing any emotion. On the other hand, Susan looked very lost about half way through.
"So if I understand, Mr Potter, you want me to acquire one of these weapons for you with my contacts in the Muggle government?"
"Yes, Madam Bones. I thought you could start at the top where once you convince them of helping, they will say jump and everyone below them will ask 'how high'," he explained with wry grin. "You may have to explain how the disasters from late summer were not disasters and were cause by Riddle and his gang, and how if we don't take care of him, they will have a lot more of that."
"Yes," she drawled, "I can see that being a persuasive argument, especially to get some old weapons they're probably about to scrap anyway. It's just so … unconventional, you understand."
"I do. Professor Dumbledore had the same problem, but I pointed out that the Muggles have had these weapons for years. Also, I think it would be good for the Wizarding World to see what Muggle weapons can do, to help the Purebloods give the Muggles more respect. I believe that one day, the two worlds will merge and we must be ready. We need to lose some of our arrogance."
Amelia gave him a grim expression and let out a deep breath. "I would like to say you're wrong, Mr Potter, but you're not the first person to say this and the longer I live I begin to believe you may be correct. Still, you leave me in a difficult position given the way things stand today."
"I understand," Harry said sympathetically. "I truly only need two things from you. One, I need you to arrange for me to get the weapon and ask for me to get a little training, hopefully in a single day. And second, I need it all to be kept to yourself, telling no one, and I truly mean no other witch or wizard. You, Susan, Dumbledore, Hermione, and myself are all who know and that's the way I want to keep it until just before it all comes down."
"And afterwards?" she asked, still not showing which way she was leaning.
"I'd like to return the weapon to the Muggles, finish up whatever school time I have left, and then live my life as normally as possible," he told her.
She glanced at her niece, who was still sitting next to Harry with a hand on his arm. "And your intentions towards my niece?" She was secretly pleased to see each of them blush, which she took as a sign that they were not that far along yet.
"We're just friends for now, getting to know one another better." He looked at the girl next to him, who pinked slightly again, but held his gaze. "As for the future ... I'm … open to possibilities."
Amelia finally let a wan smile out. "That does not affect my decision, but it's nice to hear. As for your request, I find it intriguing. Let me have lunch a few of my 'other friends' and see if I find any interest."
Harry grinned broadly. "Thank you very much, Madam Bones. I will say that this needs to happen before June."
"It's not guaranteed, Harry, but I'll do my part and see if I can make arrangements for you," she said. "In the meantime, could you please wait outside for a moment? I need a few words with my niece before you escort her back to lunch."
"Certainly," he said, doing his best not to wonder about their conversation, while quite sure it was about him.
A minute or so later, a very red Susan came out of the room, followed by an amused looking Amelia Bones. Susan reattached herself to Harry's arm as the head of the MLE bade them good-bye.
Harry escorted her back into the Great Hall, but Susan pulled him towards the Hufflepuff table. Susan sat him next to Hannah Abbott and then took the place on his other side. He rather enjoyed the Hufflepuff hospitality, not to mention the attention of the strawberry blonde who seemed to alternate between being shy and being bold.
(Ending 1 - My First Idea)
One weekend in March, he, Hermione, and Amelia Bones travelled to a government building and then to a military base. After a consultation and a brief demonstration, it was decided that a heavy machine gun was the answer. The older model did not have any electronics, and it's few modern needs, like the belt system to feed in the bullets, could be changed so magic would drive the mechanisms. That change would have to be done after they "took it home".
A couple of Squib soldiers were assigned to Amelia and went with them. Amelia created a Portkey to a desolate place for the change to the gun and for practicing. Harry used up a lot of ammo and destroyed a number of trees as well as a herd of transfigured rocks into cows. He was quite pleased with the results.
Back at the school. Dumbledore and McGonagall worked furiously one night to put up the barriers around the school.
Dumbledore also created a fake prophecy by Trelawney. Snape was given the fake prophecy the next day when he asked why the barriers were there. Dumbledore did a good acting job when he said they only had to keep Harry safe at school for two weeks.
The beauty of it was the prophecy said that unless Riddle attacked by mid-summer, he could not win. Mid-summer was in two weeks, so that should force him to attack very soon. Harry knew exactly when Riddle heard the news, as his scar hurt fiercely for an hour. Snape also returned from that meeting with a limp he never recovered from.
Hagrid visited the centaurs and told them to take a holiday deep into the forest for the next month. He then moved into the castle. Hagrid did not like living in the castle, but he understood. His class became completely theoretical.
All of the faculty understood, when they were told the next two weeks were critical to their survival and that they had to stay inside the castle. Once she understood the gravity of the situation, Professor Sprout moved a number of rare plants inside to use for classes.
To help with that survival, Susan Bones and a few other Hufflepuffs secretly made most of the sixth year Slytherins and a few seventh year Slytherins disappear into an unused area of the castle where they were kept unconscious and a prisoner. The most amusing thing to Harry was no one suspected it was the Hufflepuffs who did it. The staff all kept looking at the Gryffindors who could honestly denying doing anything to the Slytherins.
Harry's last preparation was to dig a single tunnel under the barrier and install his machine gun in. There were a number of illusions and disillusions incorporated into the defenses, so Harry's gun would not be the only piece of magic on the other side of the wall.
After that, it was only waiting and watching. Harry stayed near his area in a room just inside the castle, as did the Squib soldiers. He studied, he talked, he even had some fun, but he never left his post once Riddle had the fake prophecy. Even his friends knew they had to go to him to spend time with him.
Hermione, Ron, and Susan spent the most time there, usually telling Harry what he missed in class and helping him to revise.
One week after Snape had told Riddle, Harry was woken early one morning with severe pain in his scar. This was it, he knew. Voldemort was angry and he was about to do something. Harry quickly woke his helpers and they all got ready.
They had time for a hurried breakfast and then some until Voldemort showed up at the front gates. He easily had a hundred Death Eaters. There were also a dozen trolls, three giants, a dozen Dementors, and about forty unkempt men -- who Harry assumed were werewolves.
Dumbledore arrived as Harry was looking through the periscope on the wall to see the enemy. "There's no backing out now, Harry. Are you ready?" he gravely asked.
"Very," he said tightly. "It looks like they're all coming in. Headmaster, if you would taunt him a little, although do try to not get killed."
Dumbledore's sparkling personality reappeared for a moment. "I shall try. Professor McGonagall is reinforcing the front gate with more stone. Good luck, Harry."
Harry abandoned the periscope and crawled through the tunnel under the barrier to his machine gun on the outside. It was mounted at waist height and ready. His helpers were ready to feed the bullets, but firing it was going to be all up to him.
Riddle led his troops and stopped in before the front gate, about twenty yards out. Harry was a little off to the side of the gate, so Riddle was close and would be easy to hit first.
"Dumbledore! Give me the boy and no one else need get hurt!" Riddle shouted.
"I don't think so, Tom. I won't give anyone to you," Dumbledore's amplified voice replied.
"You can't stand against us, Dumbledore!"
"He doesn't have to, you bastard," Harry muttered. "Let's rock and roll!" he told his helpers.
Harry pulled the trigger with the muzzle of gun pointing right at Tom Riddle and held it there for almost a full second before he started to move it back and forth, covering the entire field. The gun fired over a thousand bullets a minute, so that one second on a single individual spewed sixteen bullets and cut him in half, as well as over a dozen people behind him as the bullets did not immediately stop.
A few Death Eaters were quick enough to put up a shield, but the energy of the bullets and the vast number of them shattered the shields very quickly and those Death Eaters died as well.
The trolls and giants fared no better, even though it took a few more bullets per creature to take them down.
When Harry let the gun spin down half a minute later, only the Dementors were not dead and they were fleeing.
"Take that, you murdering bastard," Harry said, just before he slumped down, glad it was all over. He looking forward to a more normal life.
(Ending 2 - Sharing Some Steel)
One weekend in March, he, Hermione, and Amelia Bones travelled to government building and then to a military base. After a consultation and a brief demonstration, it was decided that some of the older land mines would work, as long as the triggering mechanism was changed so magic would set them off, preferably all at once. That change would have to be done after they "took it home". Harry and Hermione were given a crash course in how the device worked, and then they were given multiple crates of the devices, which Amelia shrunk so they could take them all at once.
Harry and Hermione spent all of their free time over the next week making and then going into the forest to test the change. When they made the new trigger work, they started changing all of the rest of the devices.
Two weeks before mid-summer, Harry set it all in motion, starting with Dumbledore giving Snape a fake prophecy from Trelawney to be leaked to Voldemort. That night, the house-elves of Hogwarts buried land mines one foot apart across the entire field in front of the school.
Now, it was a matter of waiting. Harry had classes to try to keep his mind off of the upcoming battle. Susan Bones also helped a great deal, spending time with Harry, talking about each of their pasts, as well as some quality "couple time" in a few broom closets. He had yet to ask her to be his girlfriend, but he was finding it harder and harder not to, especially with the battle coming so soon. He was beyond ready to be normal and only have to worry about school, girls, and Quidditch.
Early one morning a week before mid-summer, Harry awoke with a sharp pain in his scar. It was not hard to guess what caused that, so he hurriedly got dressed and ran for Dumbledore's office. The old man was already up and agreed the front gates had been forced open. They both hurried to the front door and climbed up the stairs so they could stand on top of the barrier around the school. It was painful to watch the enemy horde approach and do nothing.
Voldemort stopped in front of the gates. He easily had a hundred Death Eaters. There were also a dozen trolls, three giants, a dozen Dementors, and about forty unkempt men -- who Harry assumed were werewolves. They were all within the mined area, for which Harry was thankful.
The Dark Lord wore an evil smirk as looked up at Dumbledore and Potter. "Potter, be a good lad and come on down. If you do, I won't hurt anyone in the school."
Harry chuckled to himself and muttered. "Sure you won't, you'll just have all your followers do it."
Dumbledore grunted in agreement while holding his wand ready should Riddle try something too soon.
"I only have one thing to say to you!" He paused to see if the bait would be taken. Harry really wanted to taunt the man one last time.
"You surrender?" Voldemort suggested with an evil chuckle, which caused some low laughter among the Death Eaters nearest him.
"My name is Harry Potter. You killed my father. Prepare to die. Ignio!" With the wand movement, Harry dived to the left and cast a shield over himself, while he prayed the front of the wall protected him for the worst of the blast. At the same time, Dumbledore turned and jumped, willing to risk a broken leg or hip to avoid the blast.
The entire field erupted in flames and flying shrapnel. A few small chunks of metal rained down on his shield, but there was not enough force for them to collapse it.
Harry was impressed by how quiet it was now. He took shield down and walked to the front of the barrier and looked down through the settling dust. Then he became sick and threw up what little food he had eaten that morning. There were red splotches and body parts all over the field, including near the front gate. Voldemort's body lay unmoving. Just to be sure, Harry sent a cutting curse at it and cut it in half.
Looking towards the back near the forest, he saw that even the trolls and Giants were down. Four of the Dementors were slowly fleeing. The other eight seemed to have been destroyed by the explosives.
It was a good day, Harry thought, until ringing in his ears started getting the best of him. Fortunately, his hearing did return. He was glad the war was all over and he was looking forward to a more normal life.
(Ending 3 - Playing Catch)
One weekend in March, he, Hermione, and Amelia Bones travelled to government building and then to a military base. After a consultation and a brief demonstration, it was decided that some of the older "pineapple cluster bombs" from the sixties and seventies would work. They would not even have to be changed to work with magic as they would explode after a safety pin was pulled and then they were dropped. Harry and Hermione were given a crash course in how the device worked and how to use them. They were given multiple crates of the devices, which Amelia shrunk so they could take them all at once.
As a bonus, the soldiers threw in a small "canon" and several drums of a fluid called Napalm. After a demonstration of that, Amelia Bones suggest it might be good against Dementors, which the other two had to agree with. It was truly nasty stuff.
Back at school, Harry recruited some help from his most trusted friends in the DA: Hermione, Ron, Ginny, Neville, Katie, Luna, Susan, Hannah, and Ernie. He also pulled in the Weasley twins, Bill, Fleur, Remus, and Tonks. All swore oaths of secrecy.
All of his helpers arranged to meet in the very early morning hours while it was still dark to practice banishing the "pineapples" using some training ones that could not explode. They learned how to banish (or shoot) the approximately two pound bombs to various places on the field in front of the school.
Ron took the little canon and they made it work with water so he could train. Hermione make the pump work on magic.
With everything ready, Harry set it all in motion two weeks before mid-summer. Dumbledore gave Snape a fake prophecy to be leaked to Voldemort. The non-student helpers moved into the castle, spending most of their time in the guest quarters area to hide their presence. Now, it was a matter of waiting.
Harry had classes to try to keep his mind off of the upcoming battle. Susan Bones also helped a great deal, spending time with Harry, talking about each of their pasts, as well as some quality time in a few broom closets.
Early one morning a week before mid-summer, Harry awoke with a sharp pain in his scar. It was not hard to guess what caused that, so he hurriedly got dressed, woke his friends, and ran for Dumbledore's office. The old man was already up and agreed the front gates had been forced open. Dumbledore hurried to the front door and climbed up the stairs so he could stand on top of the barrier around the school, drawing Riddle to him. Harry and friends ran to the Astronomy Tower and Disillusioned themselves.
Voldemort stopped in front of the gates. He easily had a hundred Death Eaters. There were also a dozen trolls, three giants, a dozen Dementors, and about forty unkempt men -- who Harry assumed were werewolves. They were all within range for their banishing spells, for which Harry was thankful.
"Ron, don't forget, you can't fire until our first round of bombs explodes. Also, aim for the Dementors first," Harry quietly commanded, as he picked up his first "pineapple", pulled the safety pin, and then disillusioned it. He, and everyone else who was doing the same thing were being exceedingly careful not to drop the bombs now that they were "live".
Looking down, it appeared Dumbledore was engaging Voldemort in dialog.
"Ready everyone… Oh, and I've got Riddle," Harry said.
"Dibs on Malfoy," Ginny quickly added.
"I want the trolls," Hermione told everyone.
"The Werewolves are mine," Remus called.
Harry directed the others to take various points so the whole field was targeted. When he saw Dumbledore make a gesture with both hands as if giving up, Harry simply said, "Now," and then banished his bomb.
As soon as it was flying, Harry quickly picked up another, pulled the safety pin, and banished it just as the first round hit the ground and exploded.
Each bomb exploded on impact and sent two hundred ball bearings out at ballistic speeds, cutting through any flesh that was nearby and then probably through the next couple of people as well.
As the explosions started, Ron pulled the trigger and a fiery stream left his "canon". His aim was close to the Dementors, so he "walked" it over to the foul creatures. After covering them in the burning gel, he moved the stream of burning gel around the area, trying to hit what was left of the trolls and giants. He would have tried to get Voldemort for fun, but he could not see him standing. He did noticed that Dumbledore had jumped off the barrier and was limping the short distance towards the castle; so he should be safe.
After the seventh round of bombs, Harry called, "Cease fire!" He looked through the smoke that was on the field below. The only movement he saw was dust settling. "If everyone will put the bombs you have left into my crate please," he said in a sad voice.
He hated what he had just finished, but it had to be done. Of course, perhaps now he and the rest of the Wizarding World could have a normal life as the Dark Lord was gone, and he was glad for that.
(A/N: There's probably other ways, but these seemed like the easiest and gets the point across that Muggles are far better at killing than Wizards. :)
