When the news that "King Hun Zhao Mu both picked Wanyan and set up horses" was sent to Wanyan Zonghan's army by thousands of defeated soldiers (the loss of the troops of the Jin Dynasty was not large, but it was around 3,000). Around the Pingding Military City, the attacks and killings of the Song and Jin sides were in full swing.

Dozens of artillery guns have approached the west gate of Pingding Juncheng and fired large and small pieces of stone and soil towards the wall of Pingding Juncheng.

Wanyan Zonghan himself rushed to a place less than two miles away from the west gate of Pingding Military City, and looked fiercely at the Bohai gunners in front of him who repeatedly slashed the stones collected by Alixi's auxiliary soldiers at batches, and smashed them into the Pingding Military City, which made the Great Jin Heavenly Soldiers extremely annoyed, but still stood still.

The strong military soldiers in the brigade carried ladders or trench bags, carried axes that cut rails, stood by behind the cannons, watching the scene of the stones falling like rain.

Once the guns stop firing stone bullets and mud bullets, they will launch an attack!

Each of them looked solemn, because in the past ten days, every attack they had been repelled by the Song army.

It seemed that the stones and mud bombs shot out by the cannons could not hurt the Song people at all.

Although the Song army of this era was weaker in field battles, it was weaker than the army of Liao and Jin, and it was just around the corner with the Xixia army.

But in terms of defending the city and building the city, the Song army is definitely the first-class!

It is basically impossible to use a cannon or a stone thrower to break the castle that the Song army has truly determined to defend. Even the "Huihui cannon" that was blown into the sky by later generations did not actually break the Xiangyang city... Xiangyang was besieged for nearly six years and surrendered.

In fact, it is not very scientific to use the tip gun (including the Hui Hui gun) to throw stones and destroy the city walls. Because the stone thrower is not aimed directly, but is shot in a curved manner. Those stone bullets and mud bullets must comply with the movement rules of the parabola, and they must fall from above!

Therefore, most of the stone bullets and mud bullets that are shot with the tip cannon are on the top of the city wall, and they rarely hit the walls directly. Therefore, it is impossible to make a big hole in the wall, which causes the walls above the big hole to collapse.

It is really too difficult to smash the city wall down from the top of the city wall. If you smash some thin walls, it may be possible. However, the rammed earth city walls of the Song Dynasty were generally very thick, and the thickness sometimes exceeded the height. You can run on the top of such a city wall!

How could a city wall of this thickness collapse from the top? And while the attacking side smashes the wall, the defense side can also repair it!

If it is not crushed quickly, the wall will be hit to the year of the monkey and horses. Of course, not smashing the wall does not mean that the tip cannon is useless. If it cannot smash the wall, it can smash all the fragments on the top of the city wall. For example, the bed crossbow, the tip cannon, the fence, the wooden building, etc. will be destroyed by the stone bullets and mud bullets from the tip cannon.

Without these things, the difficulty of defending the city will be greatly increased!

However, the defenders at the top of the city wall will not be killed much, because during the Song Dynasty, any city that was carefully deployed would build a female head wall (daughter wall) at the top of the city wall. This is a kind of earthen wall about five feet high, very thick, built a few feet behind the battlements. It is not only the second line of defense behind the battlements of the city wall, but also the place where the defenders avoid cannons and avoid arrows. When the enemy uses the tip cannon to fire stone bullets and mud bullets, the defenders will sit back against the female head wall and use the dead corner behind the female head wall to avoid cannons.

When the enemy archers approach the city wall and shoot feather arrows, the defenders will erect dog-legged wood on the female head wall, hang leather and bamboo fences to block arrows.

In addition, a row of fork-row rows of wood are erected in front of the female head wall, which is a wooden fence. The height is outside the battle, five or six feet higher than the female head wall. When the enemy climbs up the wall, the defenders will retreat to the female head wall, rely on the protection of the fork-row row wood, shoot arrows from a high place or poke with a spear.

The enemy who climbed the city could only cut off the fork and set up the wood with an axe to attack the girl's head wall and thus occupy this section of the city wall.

However, occupying a section of the city wall does not mean breaking the city. Because the city walls defended by the Song army would be divided into sections by sections by sections by sections by sections by sections by sections by sections by sections by sections by sections by sections by sections by sections by sections by sections by sections by sections by sections by sections, but basically breaking a whole city wall does not mean breaking the city.

Because there are usually inner trenches inside the city wall - trenches dug along the inner side of the city wall. This kind of trenches can not only prevent the enemy from digging tunnels into the city, but also prevent the enemy from further breakthroughs after the city wall is occupied by the enemy.

The standard of inner trenches is very high, it must be several meters wide and more than two meters deep!

There is also a Licheng in the inner trench. Licheng is not an inner city, but a cheap earth wall built close to the outer contour and close to the inner trench. It is usually only two meters high and is rammed with the soil obtained from digging the inner trench. The head of the Licheng also needs to be installed, and fortifications such as protection walls are generally provided.

The role of the inner moat is not only to serve as a second line of defense after the outer contour falls, but also to eliminate internal troubles... Nurhaci, who is good at using the Internet to break the city, but fortunately, did not encounter such a Song-style city, otherwise his spies would have to attack the inner moat from the city. Without siege equipment, how could they be defeated?

And within the inner city, there is usually an inner city that protects the government office... This is the so-called "two moats and three cities".

So even if you can use a cannon to smash the outer city, it is still early to break the city!

As for the offensive and defensive battle to pacify the military city, it is now in progress... The battle stage between the sheep and horse walls and the outer trench outside, and the outer trench and the sheep and horse walls are not easy to fight!

The sheep and horse wall was built against the inside of the trench. If the trench was not filled, the attacking party would not even have a place to stand.

If you want to fill a trench, you can't fill a whole trench. The Jin thief has no bulldozer, so where can you do such a big project? So you can only fill a short section. The defenders can know where to focus on the defense at a glance. Their defense method is also simple. It is to erect a fork platoon of more than ten feet high behind the corresponding sheep and horse walls that the Jin thief wants to fill. The sheep and horse walls are four feet high, and the fork platoons are ten feet high. The Jin soldiers can climb the sheep and horse walls, but they cannot jump over the fork platoons. They have to stand on the sheep and horse walls to cut the fork platoons. The Song army can shoot them with the divine arm bow and stab them with a spear...

To break such sheep and horse walls and outer trenches, it is useless to lean on the trenches alone. Because the Song army leaned against the sheep and horse walls to avoid them, the trenches could not hit others at all. Send archers to shoot heavy arrows, and the Song army on the top of the city would be accurately shot with the Divine Arm Bow. Moreover, the attacking Jin soldiers did not know if there was anyone behind the sheep and horse walls? Maybe they were hiding in the tunnel of the city gate? The outer contour of the Song-style city emphasizes "the more expensive the city gate is, not less expensive", and many small gates will be dug on the city wall during wartime, which can not only facilitate the defenders to go out of the city to attack the enemy, but also hide their troops, killing two birds with one stone.

To build other large-scale siege equipment, such as opposite buildings, goose cars, cave houses, etc., firstly, it is difficult to build, and the Jin people's Bohai craftsmen are not very good at making it; secondly, there are not so many trees around the military city to pacify, and if you want to build more and larger equipment, you have to go up the mountain to log wood, which is time-consuming and laborious...

Just when Wanyan Zonghan was in a depressed mood, he was about to issue another attack order, the general Wanyan Loushi, who was responsible for blocking Jingxing Road east of Pingding Military City, and the deputy Wanyan Xiyin, both of whom were ashen, came with a flying horse, and their faces were ashen.

Wanyan Zonghan knew it was not good at first sight, and his voice was a little dry: "What? Is there news about the Eastern Army coming?"

He didn't know that he had lost his son at middle age, and he thought Wanyan Zongwang was in trouble!

"No, it's not the Eastern Army, but the troops we sent to fight the Niangzi Pass were defeated, and they lost more than 3,000 yuan. The rest of the troops just returned and brought back bad news..." Wanyan Xiyin is a cultural person. She was not very straightforward when reporting the death to others, and she was a little hesitant.

"Bad news?" Wanyan Zonghan felt a sudden slap in his heart when he heard this, "What bad news?"

Xiyin sighed, but still didn't say anything.

The one who looked fierce and ferocious Wanyan Loushi was a straightforward and refreshing person. He simply snatched the problem and said, "Deputy Marshal, Shiya was dead. He was ambushed when he attacked the Song camp at night. He was shot to death by Zhao Kai, the prince of Yun of Song State, and he was not even snatched back. Yelu Yu saw that the old boy was missing, either dead or surrendered..."

"What? Shya Ma, he..." When Wanyan Zonghan said that, he turned black, and then he lost consciousness.
