Marshal Liu Bocheng put forward six principles for the PLA's fortification theory in "On the Basis of Defensive Operations", namely, "taking the effectiveness of defense as the first principle to reduce unnecessary casualties of our personnel", "taking the enemy's

"The principle of targeted characteristics", "the principle of rapid construction adapted to local conditions", "the principle of robustness and reliability as important", "the principle of giving full consideration to long-term persistence", "the ability to move from defense to attack

The principle of the role of transformation”.

This understanding can be summarized as six basic principles: "effectiveness", "pertinence", "rapidity", "sturdiness", "long-term" and "counter-offensive".

Although Song Biao was not an academic, his research on academic military theory was very in-depth. When he designed the fortifications in Jiangjiayao, he systematically adopted these six principles for the first time, especially when he combined "with

Based on the principle of "rapid construction according to local conditions", ice and snow from severe cold winters were used on a large scale, and a large number of ice and snow fortresses and bulletproof trenches were constructed on the spot by watering and pouring ice.

In terms of targeted design, he also fully responded to the characteristics of the Japanese Army's 31-type rapid-fire artillery, increasing the slope of the bullet-proof trench, deepening the width of the cat's ear hole, and using ice and snow on the upper layer to mainly cover and disperse the explosive force.

.

From communication trenches to command posts to frontline ammunition depots, his entire set of structures has the advantages of long-term combat and persistence.

Brigadier General Madnidorf was naturally unaware of all this. Even if Song Biaoyan confirmed that there was no problem with the construction of his fortifications, Brigadier General Madnidorf, who claimed to be an expert in this field, still planned to personally inspect the defense line.

Song Biao did not refuse, and personally took Brigadier General Madnidorf and the accompanying staff officers to patrol the defense line.

It has been a week since Hu Dalin led the engineering brigade to station in Jiangjiayao. They have completed the construction of multiple main trenches, bombproof trenches, and communication trenches in strict accordance with Song Biao's design and requirements. More than 20 densely packed trenches are connected front to back.

Dozens of snow fortresses and bunkers are interspersed in the middle as backup machine gun points.

Drawing on the experience of the Battle of Heigoutai, the Manchurian Infantry Regiment continued to set up hundreds of booby traps at different distances at the forward positions. An oil pan was set up every thirty meters on the two main trenches.

There are hundreds of foxholes in the area, both of which were prepared to deal with the Japanese army's pig-rush tactics and night offensives. The densely packed cat-ear holes can be used to avoid artillery bombardment and can also effectively deal with the severe cold weather in the Northeast.

After a personal inspection, Brigadier General Madnidoff, who had certain attainments in fortification settings, was not only relieved, but also shocked. He could not figure out why Song Biao could design such a complex fortification system.

Standing at the front of the position and looking at it, Brigadier General Madnidorf even felt an unspeakable feeling of horror in his heart. He could only sigh to Song Biao beside him: "Song, with the level of construction of your fortifications, even if the Japanese army can capture

The price they will pay for this position will be staggeringly terrifying. In fact, even if the Japanese army sends a division, they may not be able to capture such a position."

Song Biao glanced at the Japanese position in the distance and replied noncommittally: "It's hard to say, Brigadier General. The British said that you are fighting for dinner, while the Japanese are fighting for survival. I think this is not accurate enough.

The Tsarist Russian Empire was already fighting for honor at this time, and the Japanese were indeed fighting for survival. Looking back at the battles of Port Arthur and Liaoyang, I don’t think the Japanese are inherently braver than the Russians. The reason why the soldiers of the Tsarist Russian Empire were not

Fighting to the death is precisely because they have no real sense of crisis, while the Japanese soldiers have a sense of crisis. They believe that they bear the fate of the entire nation, and they are willing to die for it. These are two different kinds of morale and fighting spirit.

, although modern warfare analyzes operations into countless theories, and can even use formulas to calculate the pros and cons of the entire fortification system and every process of the war, those basic principles have not changed in the past thousands of years.

.We Chinese have a saying that has been passed down since ancient times in wars, the brave will win when we meet on a narrow road. This is exactly the case at this time. The bravery of the Japanese army will determine the outcome of this war to a large extent. As for the generals’ combat qualities,

In terms of the training level of soldiers and the organizational system of the entire army, Brigadier General, there is no need to say those false polite words between you and me. From my perspective as an onlooker, you are not as good as the Japanese army. It turns out that you still have advantages in equipment.

Now I’m afraid I’m at a disadvantage again.”

Brigadier General Madnidorf remained silent, feeling a little unhappy, but unable to utter a rebuttal.

After pondering for a long time, he and Song Biao sighed: "What you said should really be said to His Majesty, not to those of us who understand in our hearts."

Song Biao thought for a while and then said: "Actually, the Russian Empire has an advantage that the Japanese army absolutely does not have. Once this advantage is brought into play, the Japanese army will eventually lose the war."

Brigadier General Madnidorf asked in confusion: "What?"

Song Biao replied: "Time, the only thing the Japanese army does not have is time."

Brigadier General Madnidorf pondered for a moment in surprise, and suddenly understood. He couldn't help patting Song Biao on the shoulder and praised: "Song, you are really an extremely smart person. I think we can solve this problem."

A more in-depth discussion may influence some of the Commander-in-Chief’s ideas.”

Song Biao replied noncommittally: "Maybe."

In fact, until now, he had not thought clearly about whether he should help Commander-in-Chief Kuropatkin in the end. He talked with the Commander-in-Chief for half an hour, and generally felt that this person was quite good and could listen to other people's suggestions.

.

If there is the support of Brigadier General Madnidoff, Song Biao can indeed give Commander-in-Chief Kropatkin a great help as long as he speaks accurately. The question is whether Song Biao wants to say it. The pros and cons here need Song Biao to say.

Biao will weigh it himself.

Song Biao did not want the Japanese army to win this war, but he did not necessarily want the Japanese army to lose completely. In that case, it might not be beneficial to China.

…

With the arrival of Brigadier General Madnidorf and the 2nd Sk Infantry Regiment, and the reorganization of Kornilov's 3rd Infantry Battalion into the 3rd Far East Infantry Regiment, Song Biao withdrew his troops from the first line of defense.

After coming down, they were placed in Yujiayao and the second line of defense as reserve troops.

War is the best military academy. After many fierce battles, the combat level of Song Biao's Manchurian Infantry Regiment has indeed improved rapidly. From the battalion commander to the soldiers, everyone has a certain understanding of war.

, everyone began to transition from confused recruits and bandits to veterans, but we should not estimate the combat effectiveness of this unit too high or too optimistically.

Song Biao knew very well that his troops were currently only suitable to play some unique role at some special nodes and were not suitable to be used as the main force to fight against the Japanese army. Even in trench warfare, the shooting level and tactics of both sides were very different.

There is a 30% gap in execution ability. In a large battle of 10,000 people against 10,000 people, this gap will be infinitely expanded, causing huge casualties and psychological shadow.

What's more, the gap between his troops and the elite main force like the Japanese Fifth Division is definitely not as simple as 30%. If someone said that the gap was 70%, Song Biao would not refute it.

The Second Infantry Regiment of Sksk is different. Song Biao has seen the combat level of this unit. It is not far behind the main infantry regiment of the Japanese army. With the advantage of defending trenches, it can completely compete with the Japanese army in positional battles.

.

But after all, he was facing the Fifth Division, known as Japan's "Steel Army". Song Biao did not dare to be careless or negligent even if he withdrew his troops to the reserve position. Major von Eske, Major Kornilov and

His relationship can be considered very good. After their troops moved to the first line of defense, Song Biao was still on the line of defense, teaching their troops how to effectively use the fortification system he designed.

On the other hand, with the great help of Brigadier General Madnidorf, Song Biao could get all the materials he wanted. All he had to do was speed up the transportation, and speed up the transportation to the front line as soon as possible.

By February 9, Song Biao already had fifty-six machine guns on the Jiangjiayao defense line. He originally had thirty-seven machine guns. Brigadier Madnidorf brought six Marks when he came over from the headquarters.

Qin, when the Second Infantry Regiment of Sksk was transferred over, it brought 13 units with it.

Hotchkiss heavy machine guns accounted for 1/3. The ammunition for these machine guns was relatively scarce, but it was enough to last a few days.

Out of concern for the Jiangjiayao defense line, General Korbas mobilized 14 artillery companies and two infantry companies to form a field artillery regiment, and continuously moved fire from Shendan Fort to Yaotuozi, with the goal of suppressing the Japanese army.

The 5th Field Artillery Regiment of the 5th Division.

After several days of active preparations, at 7 a.m. on February 10, the 21st Infantry Brigade under the Japanese Fifth Division finally began to attack the Jiangjiayao defense line. Howitzers bombarded the position wantonly, firing more than 700 rounds.

Almost the entire position was blown up, and then the ground troops began to advance.

Because Major Baron von Eske and Major Kornilov were commanding from the front, Song Biao did not join in the fun. Brigadier General Madnidorf was personally responsible for the overall command and coordination, and Song Biao had no business.

Song Biao took more than a dozen brothers to hide in a highland bunker on the second line of defense. He took advantage of this opportunity to teach everyone, and took Zhao Tingzhu, Zhang Yahu, Xue Changqing, Leopard Chen Wu and Hu Dalin to observe the Japanese army with binoculars.

offensive tactical arrangements.

While watching, he explained to his brothers one by one the necessity of raids, organization, and tactical actions of Japanese soldiers in a small area. It was like running a crash course for non-commissioned officers on the spot.

This battle was planned for a long time for both sides, and the fight was naturally extremely fierce. As soon as the 21st Infantry Brigade came on stage, it attacked with all its strength, and the artillery bombarded Song Biao's second-line position indiscriminately, and even

It blasted towards the logistics area and command area in the rear, and the Far East Field Artillery Regiment under the command of Brigadier General Madnidorf also fired back immediately.

Artillery during the Russo-Japanese War was a very peculiar problem. The 75mm\76mm artillery technology of both sides generally came from France. The Russian m1902 76mm field gun weighed 1100 kilograms, while the Japanese army's 31-year-old 75mm rapid-fire gun actually

It only weighs 570 kilograms, but the former is a howitzer with a muzzle velocity of 588m/sec. The latter does not even exceed the speed of sound. You must know that mortars after World War II have exceeded supersonic speed. You can imagine the range and power of the 31-year-old rapid-fire gun.

Since the light maneuverability of the 31-year-old mountain cannon played a great role in the early days of the Russo-Japanese War, the Russian army actually purchased a batch of m1904-type 76mm mountain cannons from France with roughly the same technology.

As for the Russian M1902 76mm field gun, although it has only 1mm more caliber, the ballistic design and retaliation principle are completely different. The range, muzzle velocity, accuracy, rate of fire, up and down angle of attack, rotation and other basic gun performance

The 31-year-old rapid-fire artillery that completely suppressed the Japanese army.

The latter is actually a mountain artillery piece, but the Japanese army continued to name it after rapid-fire artillery.

The biggest advantages of the Japanese 31-year-old 75mm rapid-fire field gun are its easy disassembly and transportation and extremely high maneuverability, while the Russian three-inch Lucia field gun has greater advantages in other fields.

Now that it was a duel in a local area, the superiority of the Japanese mountain artillery became more and more obvious. Fortunately, the Japanese army prepared a larger number of artillery pieces and the shells were more expensive. The two sides could not tell the winner in the exchange of artillery fire, but there were some

The Russian army's larger, more accurate and more powerful field artillery restricted it, and it was difficult for the Japanese artillery to continue to suppress the position.

After losing the support of artillery, the Japanese 21st Brigade continued to attack fiercely and kept trying to move the position forward. Various temporary fortifications were piled up crazily. However, this process was too difficult, even if the Russian troops in the Jiangjiayao position had not yet fired all the machine guns.

After taking it out, the Japanese 21st Brigade also quickly suffered a major setback and suffered heavy damage.

The Japanese soldiers really didn't want their lives, the soldiers didn't want their lives, and the officers didn't want their lives either. They could still carry out standard tactical actions in the face of machine gun fire, even if they were shot dead.

Bullets rained down on the battlefield, and rivers of blood flowed from the dead and wounded.

Seeing a group of Japanese soldiers falling on the battlefield, and watching the Japanese army advance hundreds of meters one after another, Song Biao could only sigh that the Japanese army was really crazy. Zhao Tingzhu and the others also had similar emotions. They learned something from this battle.

More stuff has arrived.

Unable to hold back their inner wonder, Zhao Tingzhu and Song Biao asked: "Master, do you think the little Japanese losers are really not afraid of death?"

When he asked this question, everyone else's ears perked up. There was no doubt that everyone had such suspicion in their hearts.

Song Biao thought for a while, turned around and looked at his brothers calmly, and replied more calmly: "It's not that they are not afraid of death, but they know that fear of death cannot solve any problems, and will only make the problems worse."

It’s too bad. If even the soldiers of a nation are unwilling to make sacrifices for the nation, then this nation will eventually be destroyed by other nations. If Ming Taizu could not rise up, we can only continue to be slaves to the Mongols and suffer for generations.

Slavery will never succeed. Think about it, how many people died in the Ming army in exchange for the Han Dynasty? This is not a question of your life and death, but a question of this nation. We are Han people, we are

The Han people are different from the Manchus and the Mongols. We are one nation. We have a common ancestor, just like your brothers have a father. As long as your brother can live, you are willing to die for him.

One day, you and I will have children. You and I can't let our children be enslaved and wantonly massacred by other ethnic groups, right? Comparing my feelings, I would rather die in the battlefield than let my children be slaves of the subjugated country or other ethnic groups.

slave."

After he finished speaking these words, the brothers could no longer calm down.

Zhao Tingzhu couldn't help but ask: "Then should we rise up like Taizu of the Ming Dynasty and drive out the Manchus?"

Song Biao pondered for a moment, patted Zhao Tingzhu on the shoulder and said: "We can't think that far yet, but one day, we have to think about this problem carefully. Let's look at the present first. Neither the Russians nor the Japanese are good people.

, they all want to occupy our land, treat us like dogs, and our children will be enslaved by them, but I always feel that the Japanese will be more cruel than the Russians, they just don't show their ferocious faces.

Think about it, how big Russia is, and they won’t all move to live in the Northeast. Japan is so small. If they occupy the Northeast, they won’t drag all their families over to compete with us for land and minerals. By then, we will be able to

Have you snatched them?"

Zhao Tingzhu hummed and said: "Master, you are right. We have to fight the little Japanese thug first and earn his Russian gold notes, firearms and ammunition. What will happen next, our brothers

I’ll think about it later. Anyway, I’ll just follow your boss. We’ll kill whoever you say. Damn it, I just want to go up and fight with those little Japanese thugs.”

Song Biao said: "Let's let the Russians fight. If it's beneficial, let's rush out and get a lot of fucking money."
