In his book "On the Basis of Defensive Operations," Marshal Liu Bocheng put forward six principles for the PLA's theory of fortifications, namely, "taking the effective surname of defense as the first principle and reducing unnecessary casualties among our personnel," "the principle of taking the enemy's characteristics as the target surname," "taking the rapid construction of local conditions as the principle," "taking the solid and reliable surname as the important principle," "the principle of giving full consideration to long-term persistence," and "the principle of having the role of changing from defense to attack."

This understanding can be summarized into six basic principles: "effective surname", "targeted surname", "fast surname", "solid surname", "long-term surname", and "counteroffensive surname".

Although Song Biao was not from the academy, he was very in-depth in his study of the military theory of the academy, and he first systematically adopted these six principles when designing fortifications in Jiangjiayao, especially combined with the idea of "rapid construction according to local conditions", using ice and snow in severe winter in a large area, and constructing a large number of ice and snow fortresses and bulletproof trenches by watering and pouring ice on the spot.

In terms of the design for the surname, he also fully responded to the characteristics of the three-year-old rapid-fire gun, increased the slope of the bulletproof trench, deepened the width of the cat's ear hole, and used ice and snow as the main design to cover and disperse the explosive force on the upper layer.

From the trenches to the command posts to the front-line ammunition depots, his entire build has the advantage of long-term combat and perseverance.

Brigadier General Madenidolph was naturally unaware of all this, and even if Song Biao conclusively judged that there was no problem with the construction of his fortifications, Brigadier General Madenidorff, who claimed to be an expert in this field, still planned to personally inspect the defensive line.

Song Biao did not refuse, and personally took Brigadier General Madenidov and the accompanying staff officers to inspect the defensive line.

It has been a week since Hu Dalin led the engineer brigade into Jiangjiayao, and they have completed the construction of a number of main trenches, bulletproof trenches, and communication trenches in strict accordance with Song Biao's design and requirements.

Drawing on the experience of the Battle of Heigoutai, the Manchurian Infantry Regiment continued to set up hundreds of mines at different distances in the forward positions, set up oil pots every 30 meters on the two main trenches, and set up hundreds of foxholes between the two main trenches, both of which were prepared to deal with the army's pig assault tactics and night offensives. The dense cat's ear piercings can be used not only to avoid shelling, but also to effectively cope with the cold weather in the northeast.

After personally inspecting it, Brigadier General Madenidorff, who had a certain degree of attainment in the setting of fortifications, was not only relieved, but also felt that he was shocked, and he couldn't 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 Madenidorff even had an indescribable sense of horror in his heart, and he could only sigh with Song Biao beside him: "Song, with the level of construction of your fortifications, even if the Yue army can capture this position, the price they pay will be amazing and terrifying, in fact, even if the Yue army sends a division, it may not be able to capture such a position." ”

Song Biao glanced at the position of the army in the distance, and replied noncommittally: "It's hard to say, Brigadier General." The British say that you are fighting for dinner, and that you are fighting for survival, I don't think this is accurate enough, the Tsarist Empire is already fighting for honor at this time, and I am indeed fighting for survival. Looking back on the battles of Lushun and Liaoyang, I don't think that I was born to be braver than the Russians, and the reason why the soldiers of the Tsarist Empire did not fight to the death was precisely because they did not have a real sense of crisis, while the soldiers of the Yue Army had a sense of crisis, and they believed that they were responsible for the fate of the entire nation, and they were willing to die for it. These are two different kinds of morale and fighting spirit, and although modern warfare analyzes operations into countless theories, and can even use formulas to calculate the advantages and disadvantages of the entire fortification system and calculate each process of warfare, those basic principles have not changed in the past few thousand years. We Chinese have a saying that has been passed down since ancient times in wars, and the brave who meet on a narrow road wins, and this is exactly the case at this time, and the bravery of the army will determine the victory or defeat of this war to a large extent. As for the combat quality of the generals, the training level of the soldiers, and the organizational system of the entire army, brigadier generals, there is no need for you and me to say those hypocritical polite words. ”

Brigadier General Madenidov was silent, a little upset in his heart, but he could not say anything to refute it.

After pondering for a long time, he and Song Biao sighed: "You really should say these words to Your Majesty, not those of us who understand in our hearts." ”

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

Brigadier General Madenidorff asked puzzledly, "What?" ”

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

Brigadier General Madenidorff pondered for a moment in surprise, and suddenly understood, and couldn't help but pat Song Biao's shoulder and praised: "Song, you are really an extremely smart person, I think we can have a more in-depth discussion on this issue, maybe it will affect some of the commander-in-chief's thoughts." ”

Song Biao replied noncommittally: "Maybe." ”

In fact, he didn't think clearly until this time, whether to help Commander-in-Chief Kuropatkin in the end, he talked with this commander-in-chief for half an hour, and he generally felt that this person was still good, and he could listen to other people's advice.

If there is the support of Brigadier General Madneydorf, as long as Song Biao is right, he can indeed be of great help to Commander-in-Chief Kropatkin, the question is whether Song Biao wants to say it or not, and the pros and cons of this need to be weighed by Song Biao himself.

Song Biao didn't want the Yue army to win the war, but he didn't necessarily want the Yue army to lose completely, and in that case, it might not be beneficial to China.

……

With the arrival of Brigadier General Madenidov and the 2nd Infantry Regiment of Ssk, and the reorganization of Kornilov's 3rd Infantry Battalion into the 3rd Infantry Regiment of the Far East, Song Biao withdrew his troops from the first line of defense and placed them as reserve troops in Yujiayao and the second line of defense.

War is the best military school, after experiencing many vicious battles, Song Biao's Manchurian infantry regiment's combat level has indeed been relatively large and rapid improvement, from the battalion commander to the soldiers, everyone has a certain understanding of the war, everyone began to transition from muddy recruits, bandits to veterans, but can not be too high and too optimistic to estimate the combat effectiveness of this army.

Song Biao knew in his heart that his troops were only suitable for playing a certain peculiar effect at some special nodes, and were not suitable for fighting hard with the army as the main force, even in trench warfare, the gap between the shooting level and tactical execution ability of the two sides was 30%, and in the battle of 10,000 people against 10,000 people, this gap would be infinitely expanded, causing great casualties and psychological shadows.

What's more, the gap between his troops and the elite main force of the Fifth Division of the Yue Army is definitely not as simple as 30%, if someone says that it is a gap of 70%, Song Biao will not refute it.

The Second Infantry Regiment of Ssk is different, the combat level of this unit is what Song Biao has seen, and the gap between it and the main infantry wing of the Yue army is not large, plus the advantage of defending the trenches, it can completely fight hard with the Yue army in positional warfare.

But after all, in the face of the Fifth Division, which is known as the "Steel Army", Song Biao did not dare to be careless and negligent even if he withdrew his troops to the position of the reserves. Major Esker and Major Kornilov also had a very good relationship with him, and after their troops were put on the first line of defense, Song Biao was still on the defensive line, teaching their troops how to effectively use the fortification system he designed.

On the other hand, with the great help of Brigadier General Madneydorff, Song Biao could get all the supplies he wanted, and what he had to do was to speed up the transportation, and those that could be transported at the first time would be transported to the front line.

By 9 February, Song Biao had 56 machine guns on the defense line of Jiangjiayao, 37 machine guns in his own hands, Brigadier General Madenidov brought 6 Makqin when he came from the headquarters, and 13 when the 2nd Infantry Regiment of Sksk was transferred.

Hutchikes heavy machine guns account for 1/3, and these machine guns have a relatively low amount of ammunition, but they are enough for a few days.

Out of the importance he attached to the defense line of Chiangjiayao, General Kirbas transferred 14 artillery companies and two infantry companies to form a field artillery regiment, which continuously shifted fire in the area from Shendanbao to Yaotuozi, with the goal of suppressing the 5th Field Artillery Wing of the Fifth Division of the Japanese Army.

After several days of active preparations, at 7 a.m. on 10 February, the 21st Infantry Brigade under the Fifth Division of the Chinese Army finally began to carry out a strong attack on the Jiangjiayao defensive line.

Because in front is Feng. Major Baron Eske and Major Kornilov were in command, and Song Biao did not join in the excitement, and the overall command and coordination was personally responsible for Brigadier General Madenidov, let alone Song Biao's business.

Song Biao took a dozen brothers to hide in a highland bunker in the second line of defense, and he just took this opportunity to teach everyone a lesson, taking Zhao Tingzhu, Zhang Yahu, Xue Changqing, leopard Chen Wu and Hu Dalin and others to observe the offensive tactics of the Yue army with binoculars.

While watching, he explained, including the surprise attack and organization in the small area of the soldiers, and the necessary surnames of the soldiers' tactical movements, and explained them to the brothers one by one, which can be regarded as running a crash course for non-commissioned officers on the spot.

As soon as the 21st Infantry Brigade entered the field, it attacked with all its might, and the artillery was still bombarding the second-line positions on Song Biao's side, and even bombarded the logistics area and command area in the rear, and the Far Eastern Field Artillery Regiment under the command of Brigadier General Madenidov also returned fire at the first time.

Artillery during the Russian War is a very peculiar problem, the 75mm \ 76mm artillery technology of both sides generally comes from France, the Russian M1902 76mm field gun weighs 1100 kg, and the 31-year 75mm rapid-fire gun of the army is actually only 570 kg of its own weight, but the former is a howitzer, the muzzle velocity of the shell is 588m/sec, the latter does not even exceed the speed of sound, you must know that the mortars after World War II have passed the supersonic speed, you can imagine the range and power of the 31-year rapid-fire gun.

Because the light and mobile surname of the 31-year-old mountain gun played a great role in the early stage of the Russian War, the Russian army actually purchased a batch of M1904 76mm mountain guns with roughly the same technology from France.

As for the Russian army's M1902 76mm field gun, although it is only 1mm more in caliber, the ballistic design and the principle of repulsion are completely different, the range, muzzle velocity, accuracy, rate of fire, up and down firing angle, rotation, etc.

The latter is actually a mountain artillery, but the army continues to use rapid-fire guns to name them.

The biggest advantage of the 31-year-old 75mm rapid-fire field gun is that it is easy to disassemble and transport, and its mobility is extremely high, while the Russian army's three-inch Lucia field gun has a greater advantage in other fields.

Fortunately, the number of artillery guns prepared by the army was relatively large, and the shells were expensive, and the two sides were not able to distinguish the winner from the defeat in the mutual firing of artillery, but with the Russian army's field artillery with a larger, more accurate, and more fierce range, it was difficult for the artillery to continue to suppress the position.

After losing the support of artillery, the 21st Brigade of the Yue Army still attacked fiercely, and constantly tried to move the position forward, and all kinds of temporary fortifications were frantically piled up, but this process was too difficult, even if the Russian army in the Jiang Jiayao position had not taken out all the machine guns, the 21st Brigade of the Yue Army also quickly suffered a big setback, and the damage was very serious.

It is said that the soldiers really don't want to die, the soldiers don't want to die, and the officers don't want to die, and they can carry out the standard tactical actions in the face of machine gun fire, even if they are shot.

On the battlefield, bullets rained down, and the blood of the dead and wounded was pouring down.

Watching the first-class soldiers fall on the battlefield, watching the army advance a few hundred meters one after another, Song Biao could only sigh that the army was really crazy, and Zhao Tingzhu and they also had similar feelings, and they learned more things in this battle.

I couldn't help but marvel in my heart, Zhao Tingzhu and Song Biao asked: "Big boss, do you say that the little frustrations are really so not afraid of death?" ”

As soon as he asked, the ears of the others also pricked up, and there was no doubt that everyone had such doubts in their hearts.

Song Biao thought for a while, turned around and looked at the brothers very calmly, and replied more calmly: "It's not that they are not afraid of death, but they know that being afraid of death will not solve any problems, and it will only make the problem worse." If even the soldiers of a nation are unwilling to make sacrifices for the nation, then the nation will only be destroyed by other nations in the end, if Ming Taizu can not rise up in the past, we can only continue to be slaves to the Mongols, enslaved for generations, and never come out. Think about it, how many people died in the Ming army back then, and then the dynasty of the Han people was exchanged? It's not a matter of your life or death, it's a question of this people. We are Han Chinese, we are Han Chinese, we are different from the Manchus, we are different from the Mongols, we are a nation, we have a common ancestor, just like your brother has a father, as long as your brother can live, you are willing to die for him. One day, you and I will have children, and you and I can't let our children be enslaved and wantonly slaughtered by other peoples, right? Comparing my heart to my heart, I would rather die on the battlefield than let my children be slaves of the country and slaves of other peoples. ”

When he had said this, the brethren could not be at peace.

Zhao Tingzhu couldn't help but ask: "Then do we also want to rise up like Ming Taizu and drive out all the people?" ”

Song Biao pondered for a moment, patted Zhao Tingzhu's shoulder and said, "We can't think about it that far now, but one day, we have to think about this problem and look at the front first." The Russians and I am not good things, they both want to occupy our land, call us like dogs, and our children will be enslaved by them, but I always feel that I will be more brutal than the Russians, they just don't show that hideous face. Think about it, how big Russia is, they haven't all moved to our northeast to live, how small they are, if they occupy the northeast, then they won't all come over with us to grab the land and mine, can we rob them then? ”

Zhao Tingzhu snorted and said: "The big boss, or what you said is right, we have to fight with Xiao Yuben to the end first, and earn his Russians' golden tickets and guns and ammunition by the way, in the future, our brothers will think about it later, anyway, just follow your big boss, whoever you say to kill, we will kill whomever you say." Dog, I want to go up and fight with the little frustrations now. ”

Song Biao said: "Let's let the Russians fight, it's good, let's rush out to get a big fucking vote." ”
