In the Chongzheng Palace, after listening to Duoduo's description, Dolgon also realized that something was wrong, frowned and thought for a long time, and suddenly said: "Could it be that Liu Yan used the method of digging the city through tunnels!" ”

Duoduo also reacted suddenly, the Ming army used so much manpower, and most of the things transported were the soil that was transported after digging tunnels!

"Your Majesty, if the Ming army really digs tunnels from all sides, how can it be good!"

Dolgon said with a cruel smile: "The method of digging tunnels to attack the city is to attack the caves, and the purpose of the Ming army is nothing more than two kinds: one is to directly dig tunnels into the city, and the other is to destroy the city walls. ”

"However, it is very difficult for the Ming army to attack the city from the tunnel, and the excavated tunnel must be very wide, which can accommodate a large number of soldiers to enter the city quickly, otherwise the Ming army will die more or less when they come in; For this purpose, it is not possible to pile mounds at the corners of the walls, otherwise the defenders will only have to build another inner wall at the inner corner of the city, which will not be very wide, and the road will be completely blocked. ”

"If it was to destroy the city walls, the Ming army would dig tunnels under the walls, hollow out the underside of the walls, support them with wooden stakes, and then set fire to them. The walls will collapse after the fire breaks the supporting stakes, and the besieging army will enter the city through the gap. ”

"In this case, can our army have a solution?"

Dorgon said, "Prince Yu, immediately look for a vat in the city, and then dig a deep pit every hundred paces in front of the city wall, and put the vat into the pit, and fill the vat with water, so that wherever someone digs a tunnel, there will be ripples in the tank." ”

"Then Prince Yu arranged his troops to dig tunnels from inside the city to the outside in the corresponding direction."

Dorgon commanded Dodor with a hideous expression on his face. After hearing this, Duoduo also laughed, and said, "Your Majesty, rest assured, this time the minions will definitely cause heavy losses to the Ming army!" ”

That night, Duoduo mobilized troops and horses to begin searching the vat in the city, and the Qing army searched almost door to door, and in one night, thousands of vat were found.

Then Duoduo ordered the vats to be divided equally among the four walls, and at regular intervals he dug deep pits to lower the vats, filled them with water and quietly observed.

After a busy night, the various departments of the Qing army really gained a lot, and a lot of tunnel directions were determined on all sides of Shenyang City.

Duoduo received the news from various ministries and found that the Ming army was digging dozens of tunnels at least at the same time on all sides, and he also gasped: Liu Yan's determination is really great!

Immediately, Duoduo ordered the Qing soldiers and horses in the city to immediately dig tunnels, starting from the determined directions in various places, and starting to dig downward inside the city walls, extending outward to the outside of the city.

In the blink of an eye, on the morning of the ninth day, after a small midnight of excavation, the tunnels dug by the various departments of the Qing army have all been extended to the outside of the city, Duoduo stood on the west wall of Shenyang City, received a report from his subordinates, and after the Qing soldiers measured with footsteps in the tunnel, the distance of the tunnels everywhere should have extended to the distance of dozens of steps outside the city wall.

Dordor then ordered the divisions to stop digging, immediately deliver gunpowder to the innermost part of the tunnel, and deploy fuses to prepare for detonation.

In fact, according to historical examples, there are many ways to deal with tunnel sieges, and the most used is water siege.

That is, after the defender of the city finds out the direction of the tunnel dug by the attacker, he digs a tunnel in the opposite direction from the city, and then pours a large amount of water into the tunnel, so that the soil around the tunnel of the defender can be soaked in water, which will cause the collapse of the tunnel within a certain range, and all the tunnels dug by the attacker will collapse.

However, Dorgon and Duoduo chose to use gunpowder, although the water attack could thwart the Ming army's tunnel offensive, but it could not kill a large number of Ming troops, and only gunpowder could give the Ming army the greatest damage.

Suddenly, just as Duoduo was thinking, the artillery fire of the Ming army began to bombard again, and Duoduo hurriedly withdrew from the city wall in embarrassment, and then hid under the city headquarters to transport gunpowder to the tunnel.

The soldiers and horses of the Qing army in all departments were also crazy, and the Qing soldiers who were mobilized at this time all braved the artillery fire of the Ming army to carry gunpowder, and everyone knew in their hearts that once the Ming army's tunnel offensive was successful, the Shengjing City would also fall, and the Qing Dynasty would be completely finished!

Soon, the dozens of tunnels dug by the Qing army from the city were all completed, and at the innermost end of each tunnel, a large amount of gunpowder was piled up and connected with a fuse.

Duoduo was in a mansion in the city, which was very close to the western city wall of Shenyang City, and after receiving the report from the various departments, he immediately said in a cold voice: "Light the fire and blow up this king!" ”

Soon, the gunpowder in the tunnels was ignited one after another, and in the wilderness outside Shenyang, this land had been reduced to a battlefield in the previous few days, and it had become full of holes, but today, this land exploded one after another.

On the high platform of the Ming army, Liu Yan held a clairvoyant mirror and looked ahead, only to see one explosion after another surging from under the earth, lifting a large amount of soil into the air, which was also mixed with many human body stumps and broken arms.

Immediately afterwards, Liu Yan saw in the clairvoyant mirror that the tunnels dug by the Ming army quickly collapsed with visible traces, all of which were collapsed by huge explosions.

At this time, Liu Yan's eyes were on fire, and he gritted his teeth and said: "Order all departments to immediately dig up the collapsed tunnels and rescue the buried soldiers and people!" ”

"Order all artillery pieces to continue to stop and bombard this duke fiercely!"

"Yes!"

The officers and soldiers of the Ming army did not need Liu Yan's order, and had already begun to send reinforcements to dig the collapsed tunnels, but the soil around these tunnels had become very loose, often digging a section, and then collapsing a section, and it was impossible to fix the soil like quicksand.

Until the afternoon, in addition to the Ming soldiers and people who were buried in the outermost section of the collapsed tunnel, a large number of Ming army baggage soldiers and people in the depths of the tunnel could not be rescued, and they were buried for such a long time, even the gods could not survive.

At this point, the dozens of tunnels dug by the Ming army from all sides at the same time were almost all collapsed, and the remaining tunnels that were lucky not to be collapsed were also ordered by Liu Yan to give up, after all, the only few tunnels left are difficult to play any role, and there is a great chance of being discovered by the Qing army, in addition to adding casualties to the Ming army, it is of little significance.

At this time, the artillery fire of the Ming army was extremely fierce, and the gunners of the various departments had almost gone crazy, if it were not for the restraint of the superiors of the various departments, the gunners would not even care whether the artillery needed to be cooled, and would rather blow up the chamber than continue to bombard the Qing army.

The failure of this tunnel attack caused the Ming army to lose a total of more than 7,900 people, including more than 5,200 Ming army baggage soldiers, and the rest of the dead were soldiers and civilians.

In the Chongzheng Hall of Shenyang City, Dolgon and Duoduo laughed loudly, the two have received reports from the Qing army everywhere, especially when they heard the "spectacular scene" describing the collapse of the Ming army's tunnels one after another, I don't know how many Ming soldiers will be buried inside, which makes the two extremely excited, maybe this victory can make the Ming army retreat, at least for two days, so that the warriors in the city can take a breath.

After all, they were bombarded by more than 10,000 artillery pieces of the Ming army every day, and the warriors of all banners in the city were already embarrassed and needed to rest urgently.

"Your Majesty, the artillery fire of the Ming army is unusually fierce, it can be seen that today's victory has made Liu Yan feel pain!"

Dolgon nodded and said sharply: "That's good, let Liu Yan know that even if my Qing Dynasty is in a desperate situation, it is still unbeatable!" ”

Duoduo said: "I just don't know what Liu Yan will do next, with Liu Yan's strategy, the strategy of attacking the acupoint will not work, and it is hard to guarantee that he will not come up with other evil plans!" ”

Dolgon's heart was happy at this time, and he said with a smile: "I have also been familiar with the Han people's military books: since ancient times, the methods of siege are nothing more than siege, cave attack, flooding, fire attack, and forcible attack. ”

"Judging from the current battle situation, Liu Yan led the army to attack more than once he came up, and it can be seen that the financial resources of the Ming State cannot support the delay of hundreds of thousands of troops, so Liu Yan will not besiege Shenyang City for a long time."

"Today, Liu Yan's strategy of attacking the cave has been seen through by me, so that the soldiers are lost, and it is estimated that this trick will not be used again in the future. As for the flooding strategy, there is only a big river around Shenyang City, the Hunhe River, but it cannot be flooded in Shenyang City, so this strategy does not need to be considered. ”

"As for the fire attack, Liu Yan's army has a lot of gunpowder, once the city is set on fire, not to mention whether it will succeed, first of all, it will pose a huge threat to all departments of the Ming army, so Liu Yan will not use this method of killing one thousand enemies and losing eight hundred."

"Then there is the strong attack, yesterday the Ming army launched a strong attack, which can be described as a heavy loss, compared to Liu Yan, who has no last resort, it will not be such a fierce attack regardless of casualties."

At this time, Duoduo's eyes lit up and said, "Your Majesty means that now Liu Yan has reached the point of exhaustion of donkey skills?" ”

"Haha!"

Dorgon laughed and said, "I thought it should be so. Ordered the warriors of all banners, as long as they hold on, the Ming army will definitely return in vain, and then I will have a chance to survive in a desperate situation! ”

"Whoa!!"

Different from the elated anger of Dolgon and Duoduo, at this time, Zheng Zhilong, Li Dingguo, and the chief officers of the sixteen armies of the National Defense Army were all gathered in the big tent of the Chinese army in the west of Shenyang City.

At this time, everyone looked at Liu Yan and was waiting for Liu Yan to speak.

In today's battle, the ammunition of the artillery of the Ming army was almost all gone, and there was even a case of the artillery exploding because of insufficient heat dissipation, and tomorrow's artillery will not be able to provide fire support for the army.

At the same time, the failure of today's tunnel offensive also made the officers and soldiers of all units have negative emotions, thinking that Shenyang City cannot be attacked for a long time, and the casualties of various departments are increasing, should they take a break?

Of course, more soldiers felt extremely angry, and clamored for a continuation of the assault tomorrow, regardless of casualties, until the city of Shenyang was taken.

Liu Yan was silent for a long time, and then Zhengse said: "The failure of today's tunnel offensive is the responsibility of my father, and the soldiers of the whole army are implicated!" ”

The generals didn't expect Liu Yan to start blaming themselves as soon as he came up, and they all got up and saluted: "Success and defeat are common things in soldiers, don't blame yourself for this!" ”

Liu Yan sighed, over the years, he has relied on his own ability, as well as his familiarity with history and understanding of various technologies, and he has gone too smoothly along the way, so that Liu Yan has reached the point where he has somewhat ignored today's characters.

Whether it is Dorgon or Dordor, they are both figures who have left a mark in history, how can they not understand and guard against the tunnel offensive? ?

Liu Yan was only a little annoyed at this time, he should have expected it earlier, but he was blinded by confidence.

"In the next fierce battle, this duke has decided to continue to give full play to our army's firepower advantage to break the city!!"

Liu Yan stood up suddenly, pointed to the map in the big tent of the Chinese army, and said loudly to everyone: "Tomorrow, the officers and men of all departments will rest for a day, and all departments will send out a night to investigate around Shenyang City, find out the seriously damaged sections of the Shenyang city wall, as well as the weak sections, and report it to this public account before tomorrow evening, and order the Beiyang Fleet to continue to increase the number of ammunition delivered!" ”

"Order!"
