Time flies the slowest when you wait, but when the decisive battle comes, you will find that time passed very quickly when you look back.

Such was the case with the battle on the banks of the Kama River.

Wei Xiuzhi and Rumyantsev spent half a month, and May arrived. The Wehrmacht, whose logistical supply has already been penetrated, is ready to make the final preparations to completely eat the Russian army.

Although the logistics supply line is just a finger-thin tube, that's a good thing, isn't it? The material reserves of the Wehrmacht have been increased, and they are much cheaper than the Russian army, which is sitting on empty seats.

The traces of Russian cavalry traced around the battlefield often found the remains of wild vegetables and animal bones. In the wild, scouts can also find traces left by their hunting and digging for wild vegetables.

Facts everywhere show that the Lao Maozi cavalry troops floating outside the battlefield are very likely to be short of food.

There should still be a lot of food in the hands of the besieged Rumyantsev, but in the hands of the Russian cavalry units that rushed out that day, it is impossible to have too much. What's more, they have been floating out for half a month now.

"Now there are only 20,000 Russian troops in the circle, and without rockets, it will be easy for us to eat them."

In a word, the Wehrmacht is still strong. All the forces of the Russian army in the Ural River valley were pinned down by the city and the vassal cavalry on the Caspian Sea, while the rest of the forces were all surrounded in cities and fortresses. Without the support of this mobile force at Rumyantsev's disposal, it would be difficult for these surrounded Russian troops to even break through. Lao Maozi had no reinforcements at all, and there was no logistical supply.

When the cavalry units of the Wehrmacht began to run on horseback, the cavalry of the Russian army did not dare to get too close to the battlefield, and expanded from the first twenty li, to thirty li, and finally fifty li.

This gave the Wehrmacht a sense of security on the battlefield.

"Wait until nightfall, and use that flying thunder cannon to fight the Russian army for a while. Then send men to persuade them to surrender. In Wei Xiuzhi's words, he didn't take the 20,000 Russian troops in his eyes at all. Without rockets and artillery, fighting against the current Wehrmacht, it would be really your own death.

In the confrontation these days, Lao Maozi is indeed constantly reinforcing his position, and he can see it clearly on the hot air balloon. But there is a big gap between their civil engineering and that of the Wehrmacht, let alone the volunteers on the Korean battlefield back then.

The rabbits of the year went from horseshoe-shaped small pits to Y-shaped, H-shaped, and chicken-paw-shaped pits...... The tunnel has developed from a battle bunker to an underground fortification that integrates combat, command, and troop accumulation, and can defend, fight, and live, which is the crystallization of countless blood and wisdom.

At the beginning of the fight, the rabbit who was at a disadvantage in terms of firepower attached great importance to the trench fortifications.

In the history of time and space, during the defensive operation in the summer of 1951, some troops creatively connected two deepened anti-artillery holes together to form a horseshoe-shaped small tunnel, which was thought to be the prototype of tunnel fortifications. After the defensive operations in the autumn of this year, the Volunteer Army began to build tunnel fortifications on a large scale along the entire front.

This achievement is based on their rich combat experience and accumulated tunnel operation skills over several decades, and is not an empty castle. The Russians are still 108,000 miles away from the realm of rabbits.

Fortunately, Wei Xiuzhi is not a traverser, otherwise he would definitely use the War of Resistance and the aid of Korea as an analogy. As far as the Wehrmacht's current firepower advantage over the Russian army is concerned, it is not as good as the ammunition of the old American Van Vliet, and it is not worse than the time of the little devil.

The Russians only blindly dig deep into the trenches and fortifications, which is really poor.

And what about the Wehrmacht? In the aftermath of the rocket's depletion, they themselves are also summing up how to withstand the close bombardment of this weapon.

It is impossible for them to have an advantage on the battlefield at any time. I don't know when it will be the Wehrmacht who will have the absolute upper hand in firepower.

So how do you protect yourself from rockets?

Of course, trenches were also dug, curved, wave-like trenches, deepened from the initial two meters to three meters, and new anti-artillery holes had to be built.

Either you have to play with the anti-artillery hole when you encounter stones and mountains, or the plains are fertile, and the anti-artillery cave must also be constructed.

In view of the previous defects, the new anti-artillery holes need to be further deepened, and they must have the same twists and turns as the trenches. There should also be a roof support, which has very strict requirements. It is also equipped with drainage ditches, hidden vents, toilets and other facilities.

In the face of fierce fighting on the plains, when the Wehrmacht did not have enough time to construct a large number of permanent fortifications, it was necessary to dig trenches vigorously and form a defensive and offensive system of support points with tunnels as the backbone and various field fortifications.

Under the premise of Chen Ming, the traverser, to guide and raise points, the Wehrmacht's tunnel tactics are progressing very quickly. This is also a progress based on the original experience and foundation of the Wehrmacht itself, but the Russian army will only stand still.

The abrupt change in the mode of war is destined to sweep some of the famous veterans of the European military into the dustbin of history.

They haven't suffered enough losses, haven't paid enough 'tuition', and still have a long way to go to sum up their own trench defense system.

Of course, the transformation of the war mentality of any army, including the Wehrmacht, cannot be accomplished overnight. For example, it will take time for the current Wehrmacht units to change the impression that the anti-artillery holes formed in the previous battles are self-digging graves.

Chen Ming clearly conveyed instructions to the Metropolitan Governor's Office: the tunnel operation is not only to save himself, but more importantly, to better destroy the enemy. In the future, our tunnel operations should develop in the direction of tactical tunnels that can both hide and fight. Tunnels must be combined with field fortifications, must be compatible with defensive forces, must have equipment for combat and daily life, and must have uniform specifications and standards. In this way, the 'tunnel fortification' has become a complete system that can fight, defend, maneuver, and live.

In view of the shortcomings and deficiencies of anti-artillery tunnels and various trench tunnels on the battlefield in the past, Chen Ming also learned from the 'Zhiji' on the Korean battlefield in those years, and proposed that the tunnel fortifications must achieve the "six defenses", that is, anti-artillery, smoke, rain, moisture, fire and cold.

The above-ground fortifications must be as strong as possible, and they must also be camouflaged, and the management and maintenance of the fortifications are also very important, so that they can be damaged and repaired at any time.

But the Russian army's method is only to deepen the depth of the tunnel, although this can play some defensive role more or less.

Wei Xiuzhi is no longer thinking about the 20,000 Russian troops on the plate, he is thinking more about the Russian cavalry units wandering outside, the Cossacks and the regular Russian cavalry regiments, about 4,000 people. It's a big piece of fat. These days, these Russian cavalry have been circling around the periphery of the battlefield, and it is obviously impossible to abandon Rumyantsev.

These people really restrained a lot of the energy of the Wehrmacht cavalry, and also involved some of the energy of the infantry. It wouldn't be friendly for them to be adorned like that all the time behind their homes. Wei Xiuzhi wanted to make a trick, introduce them all into the encirclement, and stew them in a pot.

A series of arrangements don't need Wei Xiuzhi to worry about anymore, the staff in the army will plan according to his instructions, and now they are all planned. Wei Xiuzhi was very satisfied with what he heard, when the large army was eating the main force of the Russian army, it was indeed the best time to lead the Russian cavalry into the set.

With the exhaustion of rockets, the besieged Russian army is now like a dog that has been beaten down, even if it sees the Wehrmacht 'above board' pounding not far from their position, they will only use rifled guns to fire a few cold shots from a distance. But a few bullets could block the burial of the flying thunder cannon, and by nine o'clock in the evening, it was dark and I couldn't see the five fingers of the hand.

"Boom, boom, boom, boom......" A muffled sound immediately echoed between the positions.

The encircled Russian army was suddenly bombarded so violently, it was all shocking, and now the range of the flying thunder cannon has exceeded 200 meters. It almost covered the four trenches at the front of the Russian position.

Rumyantsev thought that the Wehrmacht was going to take advantage of the opportunity to fight at night. As a result, after a while, I saw that the explosion points of those shells were all in the forward positions of the Russian army, and there was still some distance from the defense line where the troops were really stationed, so I was confused again.

"If this high-powered artillery can have a range like a normal twelve-pounder gun, the Chinese will be invincible." Rumyantsev had long known about the emergence of a powerful artillery with a short range in China, and after returning to St. Petersburg, Potemkin focused on two Chinese weapons, one of which was a rocket and the other was a flying thunder cannon. But as far as Rumyantsev knows, the Chinese army has gradually abandoned the flying thunder cannon. The main focus shifted to rockets.

But now, this thing has been picked up by the Chinese again.

The sound of the flying thunder cannon is very different from that of a rocket, and the shooting curve is full of projectiles, the landing points are scattered, and the accuracy is not high. Many rockets are aimed at directly, a bit like archery, and the accuracy meter is higher in the hands of a skilled hand. There is a big difference in the power of the two weapons, but for the Russian army hiding in the deep trenches, the weapon of flying thunder artillery is likely to be more threatening than rockets.

The Russian army has dug deep trenches these days, but the roof is not fully covered with wood, which would be really lively if one fell into the trench.

Of course, everything is still Rumyantsev's reverie. The range of the rocket is too short.

In the command of the Russian army, many high-ranking officers do not think of the 'flying thunder artillery', the Chinese have long taken out the flying thunder artillery, the combat effect is not very good, but compared with the simpler and more convenient rockets, they are really not good.

It's just a matter of playing a shot and changing places. It made many senior Russian military officials look down on it.

In the eyes of the Russian army, since they already have a powerful and fast movement in their hands, they have launched fast rockets. Such backward 'projectiles' do not need to be considered.

Otherwise, the Russians really wouldn't be able to make such a thing.

There are still capable people in Russia. Just by virtue of the Banner Man's story, they are likely to come up with a preliminary product.

But the Russians have never bothered to do this, just like Britain and France and other European powers have never set their sights on flying thunder cannons.

"The Chinese are demonstrating?!" Rumyantsev was silent for a while, his brow furrowed. What do the Chinese really want to do? So many shells only hit the forward positions, is it useless at all. And if a burst of rockets occurs in the opposite position, no matter how deep the Russian trenches are dug, they will die in batches.

The smell of the rocket explosion was very uncomfortable, and the continuous bombing and explosion shook the ground, making people feel like they were riding in a small boat on the turbulent sea, and the strong shock wave stirred everyone, even if the protection was properly, many people were shocked like drunkards, and they could not stand steadily.

"The Chinese are scaring us, they are intimidating us, making us feel afraid."

"I'm afraid that the Chinese general on the other side wants us to surrender!" Rumyantsev is not a fool, and his brain quickly turned to persuasion. The Chinese army is forcing itself to surrender voluntarily. They are now flexing their muscles and scaring the Russian army.
