Su Yonglin once told Song Jun that the Super League’s long-range weapon, the three-bow bed crossbow, that is to say, the Chinese bull crossbow had unrealistic fantasies.
However, according to the professional department of the Ministry of Industry, Su Yonglin felt very depressed after learning about the three-bow crossbow captured in the Song War.
It is not impossible for this thing to shoot to 1,000 meters or even 1,500 meters. It is necessary to be willing to give up the highest grade raw materials, the best wood and beef tendon, and risk that this expensive three-bow bed crossbow will be scrapped after one launch.
It can really hit far, far away.
However, the range does not mean the effective range, otherwise Su Yonglin will be able to shoot two or three kilometers if the general gun raises the muzzle. The range is quite frightening, just like the historical records.
But what if you can’t hit the target no matter how far you fight?
It is not impossible to let the three-bow bed crossbow shoot a kilometer away, but it is not the same thing to estimate that the deviation from the scheduled shooting target can be tens of meters away.
It is impossible for the Southern Song Dynasty court to master the mathematical model of bed crossbow shooting data or calculate the range equation of a bed crossbow shooting a huge crossbow with a length of two meters.
Without the support of this mathematical data, it is hard to say how accurate the shooting is by roughly calibrating a small target hundreds of meters away with the naked eye.
Throughout the ages, it has never been said that there is a marksman who pays attention to accuracy, but few troops fight mainly by quantity, and never look at the shooting rate of a single person
The credit of the melee troops in the battlefield can be obtained at the cold feet, while the credit of the crossbowman is not obtained during the daily training because it is impossible to know who shot and killed.
According to the Ministry of Industry, they captured the limit effective range of the three-bow bed crossbow, which was about 300 meters away and was killed by the Song Jun bed crossbow. LiLin Xiao, the general of the Liao army, is estimated to be unlucky through the ages.
He probably provoked something at a casual moment to let him die in such a humiliating way.
However, if we expect the Song Jun Chengtou three-bow bed crossbow to effectively shoot the artillery group of the general of the army about 500 meters away from Fancheng, the difficulty is almost equal to the water gun hitting a mosquito ten meters away.
Don’t say it’s a skill fight. Less is also a connection with technology.
However, the effective bombardment limit of this kind of luck tactics against the general guns of the army is close to self-humiliation
Zhang Yuejing’s flying tigers are not worried about what impact Song Jun’s long-range strike will have on the army
And if in the field, Song Jun is purely a food delivery door, fighting capacity, organization and weapons. What is there to worry about in Song Jun?
[It’s really lonely to fight with the wind]
Occasionally, Zhang Yuejing will have this idea of Versailles in his heart.
However, it was his military creed that he would not spare the lion and fight the rabbit, so he gave the order to start the battle.
The first round of shooting of the general artillery group began.
After the earth-shaking roar, 25 rounds of steel shells wrapped in scorching heat flashed forward and rushed to the wall of Fancheng.
No kidding, Fancheng defenders felt complicated at that time.
They felt the whole city wall shake.
The walls are shaking!
When the shells violently hit the city wall, they not only smash the contact surface of the city wall to expose the inner wall, but also make the whole city wall vibrate.
That’s not to mention, another shell hit the wall tower very accurately. It was a shell, which made the wall debris splash and smoke filled the air. It looked terrible and magnificent, and the tower was directly torn away. The shape was very sad.
Several shells hit the battlements and shattered the battlements. The kinetic energy continued unabated and the defenders hiding behind the battlements were smashed into paste.
A shell fell on the tower and bounced directly across the tower and crashed into the city, killing more than a dozen Song Bing who were injured and burned twenty or thirty people.
After a shell smashed the battlements of the city wall, it jumped directly and hit the remaining half of the tower, interrupting two columns and tearing the remaining half of the tower badly. A lot of debris fell to the ground and splashed, and many Song Jun soldiers were injured.
And the unlucky guy was hit by debris, and suddenly he bled to the ground and twitched and died slowly.
A three-bow bed crossbow launching group is located at a higher position on the wall. A newly built bed crossbow building is launched farther and more lethal. However, this bed crossbow building was just hit by a shell.
The building shattered and the crossbow destroyed the entire launch group, and seven soldiers were also lucky enough to die in a terrible condition.
The tragic situation made Song Bing, who witnessed all this and survived by luck, scared the shit out of him and never dared to get up the courage to approach the front line and turn around and run away.
In addition, three directly crossed the wall and rushed into the city, causing great damage to the buildings in the city and the Song Jun soldiers around the buildings, which caused the city of Song Jun to fall into a great panic.
They shouted at them and cried, and they scurried around and ran away. After being so stimulated, the formed units were in turmoil, and many soldiers could not help but say that they fled to the south of the city, and the officers could not stop them.
Compared with some officers who took the lead in fleeing themselves, he told the soldiers to run away without discipline, which felt like playing the role of life and death.
The soldiers of the tower run crazy to the city, and the soldiers of the city run crazy to the city, so they should stay away from the city wall and the terror.
The morale of the defenders of the city collapsed for the first time before the army approached the wall to launch a real attack. Fortunately, at this moment, the army did not launch ants to board the city, otherwise Fancheng would be killed by the army on the first day of engagement.
For all this, Fancheng Shoujiang Joo Won  lacks psychological preparation.
At that time, Wang Yan had moved to Xiangyang City, and Joo Won  was bidding for the North Tower.
He looked at the military position far away and still couldn’t see the artillery, but when a mass of white fog suddenly rose, he felt something was wrong.
Otherwise, when the shell hits the tower, it will bring that kind of vibration. The whole tower seems to be hit by an iron fist, and then the vibration feels like someone hit him in the heart with a fist.
The shells didn’t hurt him, but the fierce bombardment of shells brought great physical and psychological blows to the city walls, towers and Song Jun.
What’s more, the defense force is relatively weak compared with the wall. The wall battlements were destroyed by military shells, and many wall battlements were broken, which greatly reduced the protection ability of the wall for Song Jun soldiers.
It is conceivable that once the second round of shooting comes to the city wall, Song Jun’s defense will be more difficult and the casualties will be even heavier
However, the problem facing Joo Won  is that the soldiers in Song Jun have fled. After receiving the report, he had to work hard to make his own personal guards send out to slay the fleeing officers and soldiers to restore the garrison order as soon as possible and arrange the defense of the military city
Encountering fear can create greater fear and let the city of Song Jun know that the tower may die if it fights, so that they will make the right choice.
This is the experience of Joo Won , the old general.
When dealing with the 8 Jin Army, they met timid soldiers, and they did the same. They wouldn’t do ideological work for you with whispers. They would show you the results of the battlefield with knives and blood and ask you-are you going or not?
Dare not go?
Before the army launched the second round of shelling, Joo Won ‘s order came to the Qinbing team. The Qinbing team resolutely carried out the large-scale dispatch of the Lord to hunt down deserters and escaped officers, carrying their heads to the front to threaten the cowardly soldiers and officers.
No, the tower will fight to the death. This is a battle. Unless you order not to build towers privately, you will kill one by one!
Chapter 153 Four questions will make a brave man.
Fierce and strong Qinbing awed the soldiers in Song Jun. They were sad and cursed Qinbing. The officers led them to the rostrum with funeral emotions to prepare for the war.
For these Song Jun soldiers, the tower battle is tantamount to suicide.
It is not a simple matter for the army to launch the second round of artillery shells, especially for the general guns that are difficult to operate.
After a shell is fired, first of all, the gunners of the gun group need special tools to shout and try to reset the gun and adjust the shooting angle according to the barrel door and sight.
Then they must take a hook brush to hook out the unburned things in the gun barrel, then dip the brush into the gun bore to clean and extinguish the sparks, and then wrap the gun stem with dry cloth and put it into the gun bore to dry it.
At this step, the gunners can fill the powder again and put it into the shell. Sometimes they need to plug something to increase the air tightness, and finally ignite the propellant and then ignite the barrel powder for the second launch.
In this process, with the increase of shooting times, it is necessary to cool the barrel for some time until the temperature of the barrel behind it is very high, so it is very necessary to pour warm water to cool the barrel slowly and maintain the firing state of the barrel.
The longer the battle, the more necessary it is to give the barrel enough time to cool down and avoid the explosion of the chamber and the loss of the life of the gun.
Because of this limitation, the number of shells fired every day is limited, so Su Yonglin ordered the magic machine to fire no more than 20 shells every day, and most of them must be fired in rotation.
When launching the general guns, the camp should pay attention to the limit and fire them in turn.
In fact, gunners don’t take turns after hitting 20 shells every day. Generally, when they hit 10 or 15 shells, they will start to prepare for rotation.
Gunners have to prepare spare tire guns when fighting, and it takes quite a long time to prepare for the process of leaving the old guns and preparing for launching in the new gun field.
This period is necessary for the current artillery, and it is also one of the biggest weaknesses of the general artillery.
However, it is very powerful, and it is the most powerful siege weapon in this era. Its advantages determine that military law will continue to improve it if it is abandoned.
For example, it is time-consuming to formulate a better method to fix the gun body and reset and adjust the shooting angle.
If this program is dropped, it will save the gun group half.
Or enhance the strength of the gun body so that gunners don’t always worry that it will explode to cool down, so it can also save a lot of trouble for gun firing.
Speaking of the second round of shooting, the twenty-five general guns roared out again.
In the earth-shattering roar, 25 iron bullets were wrapped in hot air and hit the Fancheng Tower again, which brought terrorist damage to Fancheng Tower again.
Before the Song Dynasty, Xiangyang and Fancheng towers were earthen cities, which were rammed by layers of rammed earth, but they were strong and durable without bricks.
In the Song Dynasty, especially in the Southern Song Dynasty, due to the important strategic position of Xiangyang and Fancheng, the court of the Southern Song Dynasty spent a lot of money to pack bricks for the city walls.
