Fortified fortresses were often breached from within, and even Masada's impregnable defenses were eventually slaughtered into the city by the Romans with mounds of earth and captured the city.

Digging tunnels is a very common tactic in siege warfare, and cave warfare has been used in warfare as early as the Spring and Autumn Period.

It's not that the governors and guards of Danzhou didn't think of the cave ground tactics, but they didn't expect the Song army to use the cave ground tactics at the same time as the bulldozing method.

It was only at this time that they realized that they had been fooled, and the Song army outside was piling up dirt and slopes to hide people's eyes, and their main way of attacking was to attack through tunnels.

By the time this was realized, it was already too late, and outside the city was the Song army's wave after wave of attacks. The city was also faced with a steady stream of Song soldiers pouring out of the tunnels.

At this time, the defenders in the city need to fight desperately to kill near the tunnel, and then find a way to block the tunnel.

But the morale of the soldiers in Danzhou City was not high, and they were suddenly wrapped in pies, and they had no fighting spirit at all. No matter how those officers mobilized, they could not organize effective resistance.

The balance of victory and defeat was completely tilted in favor of the Song army, and in less than an hour, the defenders began to rout. After another stick of incense, the Song army had already controlled the city defense of Danzhou City.

The remaining remnants of the defeated army made a senseless resistance near the mansion, and when the Song army reached the edge of the mansion, Zhizhou took the lead in running out and surrendering.

Seeing this, the remaining Jin soldiers also dropped their weapons one after another.

Tang Ning didn't have time to take care of these captives, so he sent people to collect the captives near the palace, climbed the city wall himself, and began to direct the soldiers to prepare for the next Jin attack.

When the Song army arrived at the palace, the scout reported that he had seen the traces of the Jin cavalry, and the cavalry was nearby, so the rest of the troops would not be too far away.

Sure enough, an hour later, as soon as the Song army filled in the tunnel, the scouts reported that the traces of the Jin army had been detected ahead.

At this time, Wanyan Zongwang was discussing his next move with his advisor.

"Second prince, according to his humble opinion, now is a good time to send troops."

"Why?"

"You see, the Song people have just occupied Danzhou City, which means that they have just experienced the battle, and they have not rested yet, it is a good opportunity for us to attack.

Take advantage of his illness and kill him, if we give them a chance to breathe, then we will be unpredictable. ”

Wanyan Zongwang thought for a while, nodded and said, "Okay!" Do as you say! ”

Subsequently, the three armies were ordered to prepare for battle.

As the strategist said, the Song army had just experienced a fierce battle, and the battlefield had not even been cleared. Downing in the city

Before the representatives of the people saw it, the Jin army had already killed them.

The situation was obviously unfavorable for the Song army, and with the scale of Danzhou City, it could not accommodate more than 100,000 troops. This means that some soldiers must fight the Jin army outside.

However, the Jin army still has cavalry in hand, and if the troops outside do not prepare the things that need to be used in positional warfare such as rejecting horses, I am afraid that they will suffer a big loss.

At this time, Lu Qiren was directing the soldiers outside the city to dig a trench, and there was a ditch every twenty steps, and only three or four were dug out, and the Jin army was already in the face.

Lu Qiren hurriedly asked those soldiers to withdraw, and then set up their horses, set up their spears, and prepared to meet the enemy.

The Jin army really sent cavalry to charge the battle first, but unfortunately the number of trenches was too small. These Jurchen knights, skilled in equestrianism, easily crossed the trench under their feet without slowing down at all.

The Song army, which was backed by the city, was nervously preparing to meet the Jurchen cavalry rushing up, and while listening to the sound of arrows cutting through the air overhead, he couldn't help but start thinking crankily in his heart.

There won't be an arrow that flies halfway and loses its strength and lands on you.

These Jurchen knights were given a death order, and they must destroy as many Song defense formations as possible in the first time, so that the Tiefu Tu that rushed into the formation next could inflict huge damage on these Song infantry.

The dirt slope piled up before the Song army outside the city was used by the Jin army. The crossbowmen of the Jin Kingdom climbed the earthen slope and began to shoot at the Song crossbowmen on the city wall.

Wang Sunsin hid inside the city wall, through a demolished brick hole, sniping insidiously at the officers of the Jin army.

There are also eight bull crossbows and whirlwind cannons on the city wall to pour crossbow arrows and stone bullets towards the military formation of the Jin army's infantry, but unfortunately the gunpowder is not enough, if the gunpowder is sufficient, the whirlwind cannon can completely project gunpowder, thus causing greater damage to the Jin army.

The attacker uses cavalry to break up the defender's infantry defenses, which is a basic tactic. However, in the face of the Song army's defense, they did not take advantage of it.

Although the infantry corps of tens of thousands of people was huge, it still had its back to the city walls. There were also trenches to slow down some of the cavalry, and with the rejection of horses and spears, it was difficult for the cavalry who rushed forward to do anything.

Moreover, the crossbowmen of the Song army on the city wall were still shooting wildly at them, and their living environment was quite bad.

In the end, the Jin army was depressed and found that even in the face of such a Song army that had just fought fiercely, they could not take any advantage, so they retreated to the rear and set up camp.

The giant wood consumed by the Jin army in Danzhou was collected by them and made into catapults, plus they themselves brought six catapults over, and when the siege began early the next morning, the nine catapults tilted huge stone bullets towards the Song army.

Some fell on the walls, some in the crowd. No matter where it falls

Fang, the powerful destructive power of the catapult can always cause a lot of damage to the Song army.

But you have a good plan, and I have a wall ladder. The Jin army besieged the city of Danzhou and used the slopes previously created by the Song army to attack the Song army inside the city.

Tang Ning asked his subordinates to dig up the filled tunnel again, return the same way, and drill out of the ground that night, giving the Jin army a surprise attack.

At the same time, the Song army, which failed to enter the city, also followed and killed, and the Jin soldiers defending the southern side of the Song army were killed and scattered.

Wanyan Zongwang was awakened from his sleep, and when he heard about it, he was in chaos.

"What? The troops to the south have already been routed? That...... So what do we do now? ”

His lieutenant general thought for a moment and replied, "The matter has come to this, second prince, we can only join forces together and fight with the Song army!" ”

“……”

On the third day when the city of Danzhou was surrounded by the Jin army, the last snow had fallen, and the snow on the ground had just melted a few days before, and the second snow had also fallen.

Because of the weather, the Jin army had to stop attacking today. However, this snow is not the right time, at least for some time after today, and they are unlikely to attack again.

The city of Danju is on high ground, and when the snow melts, it turns into ice, which will undoubtedly hinder the efficiency of the Jin army when it is launched.

"It seems that this is providence." Wanyan Zongwang said with emotion.

Last night, he had followed the advice of his advisers and ordered the soldiers to withdraw from the other city gates, preparing to fight the Song army directly at the north gate.

It seems that the Song army has not detected this incident yet, at least the soldiers they deployed outside the north gate are still pitiful.

The strategist suggested that regardless of the weather or snow, attack the city of Danzhou directly. Wanyan Zongwang was a little resistant to this proposal.

But after everyone discussed, they all raised their hands in favor of the strategist's opinion, and Wanyan Zongwang had no choice but to agree.

He is good-natured and good at listening to people's persuasion, and he is a more democratic person. is more self-aware, knowing how many pounds and taels he has. Since everyone is going to do this, he won't be stubborn.

So in the early morning of the snow, the Song and Jin armies finally broke out outside the city of Danzhou, the largest war since the beginning of the war.

The person who took the lead in the attack was unexpected, and it was the Song army who attacked first.

It turned out that last night, the Song army had already detected the movement of the Jin army. found that they had begun to transfer, so Tang Ning didn't sleep all night, discussed with Lu Qiren and other generals all night, and finally came to the conclusion that the Jin army was preparing for a decisive battle.

He also formulated a strategy, preparing to attack the Jin army when they were preparing to attack, and take them by surprise......
