On the second night of the Russian army's full-scale attack on the German position, Lin Youde waited in the office until late at night, reading the battle summary of the high command for the first time.

This time, however, there was no Isabella to relieve his fatigue - she had already traveled to Poznan with the new Shinki with her magic armor to prepare for a possible Russian Shinki offensive.

In the huge room, only Oh-chan, who was sleeping on the sofa, was left to accompany Lin Youde, which made Lin Youde feel a little lonely.

The situation on this day was generally one in which the front line was withdrawn in good order, with the units surviving the battle assembling at the selected location of Army Group A Headquarters, and the troops newly transported to the front line reinforcing their defenses in the satellite cities outside Warsaw, preparing to rely on the cities for defensive operations.

The report specifically mentioned the will of the Polish military and civilians to fight, and the staff officer who wrote the report praised the Polish army's grassroots units for showing a higher desire to fight than expected, and at the same time sarcastically ridiculed the middle and high-ranking Polish officers as a bunch of pus.

In addition, it was the loss of Lublin, and the Polish army command swore that Lublin could hold it for two months, but this morning the commander of the Lublin garrison sent a telegram, saying that the Russian army had taken control of most of the city, and he was about to destroy the code book and the text to make a final stubborn resistance.

It is not known whether there is "stubborn resistance" Lin Youde, but the German army's aerial reconnaissance seems to show that the effect of this stubborn resistance is not particularly obvious.

As a result, Warsaw remains in the entire central part of Poland.

There is still some confidence in the defense of Warsaw, a large city like this, as long as the resources hoarded in the city are sufficient, and the troops are sufficient, will often become a meat grinder for both sides, and World War II in another time and space has fully proved this. If the Germans can secure the supply line behind Warsaw, so that the Russian army cannot complete the siege of Warsaw City, then the certainty of defending the city will be greater.

At that time, Lin Youde will order his Shenji girls to move forward and advance to a place where Warsaw can be directly covered, and then a situation of strategic stalemate will be formed.

For this reason, Lin Youde has ordered the transportation deployment to be adjusted according to the actual capacity of the railway line, so that many troops can form a defense on the road to Warsaw, and prepare to fight the Russians to the end on the Polish plain.

Lin Youde was thinking back to the details of the order he had signed when the door to his office was opened from the outside.

Ysera's head poked in, first looked at Lin Youde, and then glanced at Oh-chan who was sleeping with a rabbit puppet on the sofa, and then opened the door completely: "Okay, we should be able to go in." ”

"Hey," Lin Youde looked at his eldest daughter with some tears and laughter, "What were you just confirming?" ”

"I'm avoiding unnecessary embarrassment." Ysera tilted her head at Lin Youde, "Or do you want Lilith to chase after you and ask what you two are doing, why is Oh-chan peeing on you?" ”

"Oh-chan, is she going to pee on Daddy?" Lilith, who had already flapped her wings and flew above Lin Youde's head, looked back at Ysera strangely, "What's going on?" ”

"No, no, there won't be such a thing." Lin Youde glanced at Isera as he spoke, his expression a little helpless, "What are you doing here so late?" ”

"Because the eldest sister said that Dad, you will be lonely, so we are here to accompany you." Nia hugged the back of her head with both hands and said with a nonchalant expression, "Now I think the eldest sister thinks too much." ”

"Dad, aren't you lonely?" Lilith landed on Lin Youde's shoulder, riding Lin Youde's neck with both legs, and looking at Lin Youde's face from the side.

"No, but you're still more than welcome here."

"Well, but what is loneliness?"

Lin Youde laughed and gently touched Lilith's head.

At this time, Ysera climbed to the place where her biological mother often sat and looked at Lin Youde with a serious face. Lin Youde instinctively realized that Ysera actually had something to ask, so he ran over with his sisters.

So he ignored Nia, who began to look through the battle report curiously after flying onto the table, and said to Ysera with a smile: "What's the matter, is there anything you can't figure out?" ”

"I didn't understand why the retreat would be successful. Won't the enemy pursue? It stands to reason that if one of the two armies in the battle retreats, the other side will generally keep chasing and continue to kill and damage the enemy, right? That's why there are those suspicious tactics in ancient books that were specially thought up for retreat, especially in China, where there are many such records. But now, Dad, you let the troops start to retreat in broad daylight, and there is no plan to deploy any suspicious troops...... Why didn't the Russian army pursue? Theoretically, as long as the Russian army keeps pursuing, there is no way to stop the retreating troops from regrouping, right? ”

Lin Youde smiled.

"Daughter, you probably haven't seen the analysis of specific infantry combat examples, have you?"

Ysera nodded and said, "I haven't had time to look at these details yet, I'm trying to grasp the big theoretical direction." ”

"Well, I'll give you a brief explanation." Saying that, Lin Youde took a piece of paper - when he took the paper, he found that Nia had also stopped reading the battle report, and looked at it with little interest, so he was more interested, he drew a line on the paper, and then pointed to the line and said, "The battlefield in the eyes of ordinary people is probably like this, the two sides face each other across a line, in fact, many books for non-professionals also like to use such a simple and clear way to introduce war." But in fact, after entering the age of firearms, this kind of battlefield with clear boundaries between the two sides gradually disappeared. This is what the actual battlefield looks like. ”

Lin Youde turned the paper over and drew a bunch of circles of different sizes on it, which were distributed all over the paper. Then Lin Youde put a slash on the part of the circle.

"Look, the circle with a slash is our army, and the blank circle is the enemy's army, and there will be no clear demarcation line on the battlefield in modern warfare. Such a wide strip of area is the true face of the military demarcation line between the two sides that we see on the map. ”

"I see, but what does this have to do with the retreat?"

"The relationship lies in the fact that the situation on the front line is so complicated, and it is difficult for the commander to judge whether the enemy has retreated or not." Lin Youde continued to draw on the paper, "In this way, the empty space between these two areas that belong to the enemy and us is likely to be about one kilometer wide, and the least is four or five hundred meters, and it is very likely that there will be a lot of things that block the line of sight." In this completely fragmented front-line zone, each commander has limited information to understand, and their judgments will be full of all kinds of errors, which often appear fragmented and even contradictory when summed up in the command center at the next level.

"In this state of confusion, by the time the commander who can decide whether or not to conduct a large-scale pursuit operation has judged the situation, it is likely that the enemy's retreat has already begun for a long time. Of course, if conditions permit, it is still necessary to carry out a deceptive operation, but in the current situation in Poland, our army does not have the time and strength to carry out the deceptive operation, and can only rely on the courageous operation of the troops after the break to create a false impression for the enemy and interfere with the enemy's judgment. ”

"I see, but wasn't it like that in ancient times?"

"In ancient times, the battlefield where the two armies fought often looked at a hill, but of course the situation would not be so complicated."

Ysera nodded, and then Nia said, "No wonder Dad, you always emphasize reconnaissance, in this case, whoever can find out the enemy's movements more quickly will be more advantageous." ”

"What is Scouting?" Lilith was unwilling to be lonely and asked Lin Youde's hair, but Lin Youde obviously didn't feel the pain of his hair being pulled.

"Intelligence is the top priority at every level, and the side with more accurate and adequate intelligence will definitely gain an advantage. But the share of intelligence is different at different levels. At the strategic level, almost every aspect of decision-making is evenly divided, and commanders must not only be sober-minded about intelligence, but also have sufficient foresight. At the campaign level, accurate interpretation of intelligence has become the key to the victory of the campaign, and this intelligence includes not only the enemy's intelligence, but also the situation of our army in all aspects. ”

When Lin Youde said this, he realized that Lilith was pulling out his hair, and he hurriedly turned his head to look at his little daughter: "What's wrong?" ”

"What is Scouting?"

Lin Youde smiled at his daughter and said, "Investigation is ......"

Suddenly he found that he could not find a particularly good way to describe to his little daughter what it meant to be a detective, and Isera said, "I just told you to wait outside first, and the practice of probing in and taking a look yourself is a kind of detective, Lilith. ”

"Oh." Lilith nodded as if she didn't understand, "And what is the information?" ”

Lin Youde thought to himself, this little guy is going to be endless, at this time Nia said, "Lilith, let's go for supper, okay?" ”

"Good!" Lilith immediately bit the hook and shouted happily, "Supper, supper!" ”

At this time, Oh-chan, who was lying on the sofa and falling asleep, seemed to be touched by the word "supper", she sat up, yawned and turned her head to look at Lin Youde.

"Oh-chan, too, supper?" Nia asked aloud.

Oh-chan tilted her head, then nodded.

"Let's go! Let's go for supper! Nia jumped off the desk and ran towards the office door as she yelled, and Lilith flew into the sky and ran out with her sister happily.

Oh Chan stared at Lin Youde for a few seconds, then jumped off the sofa and ran away.

Lin Youde and his eldest daughter were left in the room.

"It's nice that they're so carefree."

Ysera said.

Lin Youde smiled and responded: "Seeing their carefree appearance, I feel that my work is worthwhile." ”
