That was on May 28, 632, the Continental Calendar.

I was only 11 at that time, a freshman at the cadet school. He hid his true identity and ran a cadet school life while naming himself Emilia Vistula.

And some of the grades I belonged to were voluntarily residing classes as every day to enhance their own abilities. I also took part in it and encouraged drilling with everyone. I studied swordsmanship from Maya, equestrian and archery from Sarah, arithmetic (accounting) from Radek, and tactics and strategies from Yuzef, and I spent my days teaching you witchcraft.

And after school this day, it was Mr. Yuzef's tactics and strategy class. His eyes shine a little when he talks about what he calls tactics. I just want to talk for a long time, because of my strong feelings. It's a flaw in the balls (without) that I have a poor way of explaining it.

---

"No matter how times shift, no matter how magic and technology evolve, it doesn't change how much a war must win."

That's how he cuts out and starts classes.

"Is there such a thing as a must win?

Question as naturally asked by Maya. If there's such a thing as a must-have, everyone should do it. It wouldn't make sense if everyone used the same method.

"Yes, Mr. Valta."

"What the hell is that?

"It's easy." Gather more soldiers than your enemies ". That's all."

"Ha..."

Maya has a slightly clapped look. Because I was hoping for what magnificent tactical theory would pop up, but in the end it was just a simple addition and deduction.

Other learners, especially Sarah, have clearly shown dissatisfaction with this answer

"... that's boring."

"If you find the war interesting, that's not gonna work."

Ms Waresa said that, but I am also certain that this is not boring, as Sarah said.

"I mean, is that it? Collect a multitude of soldiers and weapons in case of war, and the country that can feed it wins! So you're saying?

"That's the thing. They say why the big countries are strong, so Radek's right, they can feed a lot of soldiers."

"I don't know..."

"Well, I know everyone's dissatisfied. Collect as many as you can and hit your enemies."

Mr. Waresa scratches his head as if he was in trouble. I know the logic, but I guess it means he's got a lot of grievances himself.

But if you stop here, there's no point in staying. This remaining class is not passive, and the goal is to actively voice your opinions and build drills from here.

I raise my right hand quietly and hit Mr Waresa with an opinion, no questions.

"Mr. Waresa. May I ask you a question?

"Go ahead, Emilia."

"Thank you. I understand what Mr Waresa is saying, but is it true that the difference in numbers is the difference in force? There are many examples of war history where a small number of soldiers have defeated a large number of soldiers."

When I say that, Ms. Waresa says, "I've been waiting for that question! I just looked at him."

"Master Emilia is right. There's a battle in war history where 10,000 soldiers have driven away 20,000 soldiers."

"So you're saying that the difference in numbers is not a decisive difference in your power of war?

"No. The difference in numbers is a decisive difference in power. That is in principle the truth. Even if there were a thousand heroes on one horse, the limit is to defeat a thousand soldiers on one. A thousand heroes on one horse would fall. Not to mention the limits of a well-trained soldier."

"... you're not convinced"

Really. Wouldn't this destroy the small military Power, the Kingdom of Silesia? That's all I thought about then.

"But as I said earlier, there are as many examples of widows driving away their great enemies as there are. Let me teach you how to do that today."

"Please"

Once she coughed up, Ms. Waresa started drawing some diagrams on the blackboard. Two "convex" on the left and three on the right, that's relative. Is it an assumption that there are two divisions on the left and three divisions on the right?

"The troops who participated in this Blackboard match were two divisions of the West Army and three divisions of the East Army. There's nothing to block here in the plains. As the magic skills and soldier proficiency of both armies and the abilities of each division leader are the same... then Sarah, which one is in your favor in this case?

"If the left is our army, the left wins."

This statement by Sarah feels more like saying that she trusts her peers' abilities than saying that she is confident in her own.

"No, unfortunately, we're still cadets, so I don't think we're in this blackboard match."

"Then the right is in your favor. As far as listening to Yuzef earlier"

Sarah flips her foreword lightly.

"Yeah. Correct. Right, but the East Army can crush the Left Army if they don't think about it. Even if one East Army took a tactic that would be heartfelt with one West Army, the East Army would remain one division. Next, then."

Mr. Waresa crushes the East Army with a single blow because he wiped out the blackboard. Pathetically, I didn't have one child left.

And let me summon a new division again. Again this time 3 divisions, but unlike earlier...... no there is no up or down on the battlefield, so in this case it would mean we are in formation away from the north and south. One, two, three and the number are flushed from the top.

"Now in the case of this second Blackboard match, the East Army inevitably divides the three divisions into three parts for strategic reasons, marching from three directions. The West Army dispatched two divisions to intercept this. Conditions are the same except for placement. Bye...... Mr. Varta. In this case, which one wins?

"What... the East Army if it's just a few fights... But if that's the answer, I wouldn't bother to rewrite it, would I? You mean there's an element of the West Army winning, right?

"Ma, that's true. As Varta said, the West Army is also advantageous in some ways."

"What do you mean?

"Because the West Army stands in favor of numbers."

Maya tilted her neck. Instead of that, everyone in the classroom is tilting their necks. I don't know what that means either.

"Uh... Yuzef. Just a little easier to understand."

"Well, wait, Radek. I'll explain it in order."

Mr. Waresa writes something on the blackboard again. An arrow extending from the front of the western army, is this a line of action for the troops? Does that mean the West Army is moving forward and storming the East Army Division 2 in the middle?

"Now let's narrow our horizons. Mr. Maya, this West Army and East Army 2nd Division. Which one wins?

"The West Army. Double the number."

"Correct. The West Army has lost 2-for-3 in overall strength. But this battle in the middle, just for this one thing only, turns around and the number of advantages leans towards the West Army, and if it's a two-on-one, no-nothing plain showdown, you can't lose first."

"I see..."

Nod as if everyone was convinced. This will destroy a division of the East Army in a manner that is almost complete victory.

"And the two remaining East Army divisions are also divided up and down, so if I knock them down in the middle, I'm going to hit either ① or ③?

"Sarah's right."

"You want to be beaten up?

"I'm sorry."

Discuss one division in the center of the East Army in two divisions, and then one enemy of the North and South lovers in two divisions. And discuss who stays at the end. So that's it. This allows the West Army to win even if they are losing by an overall number.

"Create a local number of advantages to destroy each enemy. said the great old man." I will do everything I can to beat the power of my enemies. "

"Who said that?

"... uh, Sonsi?

"That's an unusual name..."

Nor have I heard of it in oligarchy, but the logic goes through. But a few questions remain.

"Mr. Waresa. May I?

"What is it, Emilia?"

"If the East Army finds out that the West Army beat the center to its full potential, shouldn't the East Army rally divisions divided between North and South?

"That's sharp. But how do you want us to meet?

"What?"

"I can't tell you just where to assemble at that point. We'll just have to get the horse out of the transmission, but it won't be easy because the center is broken. It's time consuming and inefficient to interact with the horse of the decree. While we're having that conversation, the West Army may be moving north or south to destroy each of them."

"Right."

I thought I could beat Mr. Waresa with tactics. Apparently not.

"No, but it's not a bad idea. If the commanders of the 1st and 3rd divisions of the East Army were excellent, they would assemble their troops once and for all. That way the East Army is two divisions. And the West Army should be down in numbers and the general's health under the influence of engaging with East Army Division 2. In that case, even the same two divisions would be able to carry things in the East Army's favor."

"I see...... That way, the East Army can take advantage of the difference in overall strength."

"That's what I mean"

It's a difficult one. Tactics are.

"You can say that half of what Emilia said earlier, the battle that defeated a large number of enemies with a small number of soldiers, was caused by this destruction of each of them."

"So what about the other half?

"The rest are terrain, surprise attacks, and then the incompetence of the commander."

"I can't save you in the end."

"Not at all. Right. But it's worse for a soldier who fights under such incompetence. I'm studying hard right now to avoid that."

Having said that, Ms. Yuzef forcefully ended the second Blackboard match and went into introducing examples of the actual battles of each destruction that took place on the continent.

"… Your Highness. His Highness Emilia."

"... Yeah, ahhh... Maya......"

"Are you tired?

"Oh, did I fall asleep..."

I noticed that I was sleeping on my executive desk set up at the Silesian Interceptor Command.

"I've been working too much here lately. It won't be long before the war begins, so rest easy. Leave the rest to me."

"No, that's not..."

That's not true. I can still go. I tried to say that, but I was still drowsy. My hands and feet, they don't move as much as I think. Proof of fatigue.

"Is Maya okay?

"Yep. Unlike His Highness Emilia, I work out."

"Isn't it like I'm a sprouts? Even I..."

Even I should have worked out. But I've had a lot of clerical work here lately as a senior counselor, and I didn't do sword arches or anything.

"Excuse me. Sweet for your words, I'll give you a break"

"Yep. Take your time."

I leave the office and open the door to the women's barracks. But before I do, I need to tell Maya before I forget.

"Maya. Will you wear your sword archery for the first time in a long time if you win this war?

Maya replied with a cheerful smile that did not show tiredness after a slightly unexpected look.

"I'll work out with Bishibashi."

"Hehe. I'm looking forward to it."

When I heard the satisfactory answer, I closed the door.

It is March 26, 637 at 8 p.m. Continental Calendar.
