Gao Qiqian took a group of brocade guards and a little eunuch, in the name of the prison army, in the past two days, he went deep into the officials and soldiers of the city defense under his jurisdiction, strictly carried out an investigation, urged the officers and soldiers defending the city to fight to the death and not retreat, and asked the emperor's will, claiming that if anyone retreats from the battle, he will kill his head.

On the morning of the general attack, Yu Xiaotian also asked his subordinates to give an ultimatum to the defenders of the city at various city gates for the last time, and shot a letter towards the city, which was written by Yu Xiaotian "himself" to these defenders to persuade them to surrender.

He is going to attack the city now, it will definitely cause some casualties to the defenders, he is very sad and unbearable, but for the sake of the Ming Sheji, he has to do this, hoping that these officials and soldiers can get lost, take Gao Qiqian down, open the city gate to welcome him into Beijing, and after he clears out these black sheep in the court, he will definitely return the world to a Lang Lang Qiankun, and Lu Xiangsheng a clean slate.

This letter was copied and written by the scribes of the army, and was scattered to the city by the archers, and some of the letters that shot at the head of the city were immediately confiscated by Gao Qiqian's men, but some of the letterheads still fell into the hands of the guards of the city, and some people did not know how to read, so they hurried to find a literate person to read it.

The contents of the letter immediately spread like the wind among the defenders, and those who heard the contents of the letter were even more demoralized.

As soon as the morning came, Yu Xiaotian gave the order for a general attack, and then the artillery positions that had been arranged long ago immediately sounded like rolling thunder.

All kinds of shells whistled and smashed heavily into the battlements on the city wall, and after the first and second rounds of calibration, the larger and more accurate the artillery of the Yu family's army.

Within a few hundred steps, with the accuracy of the artillery of the Yu family army and the suzhì of the artillery, the target of the battlement mouth is simply a piece of cake.

In addition, the enemy towers in the city are not a problem, and it can be said that after the school shooting, the next shelling is almost completely missed.

Under the heavy artillery bombardment of the home army, one after another the enemy platforms were quickly hit by the bricks and stones, one after another were destroyed and collapsed, and the officers and soldiers who fought to defend the enemy platforms were scurrying with their heads in their hands, and they fled from the enemy platforms one by one.

With the artillery bombardment launched by the Yu family army, the official army on the city was also ordered to start firing back, and the number of artillery on the city wall at this time was not less than that of the Yu family army, and there were many of them with some heavy Hongyi cannons.

So the officers and gunners were reluctant, so they had to operate the cannon to ignite, only to see that the city wall suddenly spit out clouds of flames and gunsmoke, and the cyan, black, and gray gunpowder smoke suddenly filled the entire battlefield sky.

Various types of shells on both sides, whistling through the air, smashed to the top of each other's heads, such a scene, it can be said that in the history of the Ming Dynasty, never seen, firearms at the beginning of the war, became the master of the battlefield.

It is a pity that most of the artillery guns of the officers and soldiers are old-style artillery, with short range and poor shooting accuracy, and the gunner's training is extremely lacking, and many artillery pieces have no aiming at all, and they all rely on the gunner's experience to aim, and the amount of charge is also determined according to the gunner's experience, which makes their artillery accuracy even worse to death.

At the beginning of the artillery battle, the artillery of the official army was completely suppressed by the artillery fire of the Yu family army, although they also fired a lot of shells, but the vast majority of the shells fell on the open ground, which did not pose much threat to the artillery positions of the Yu family army at all.

Moreover, the artillery position of Yujia's army was built very well, the main body was piled up with soil, and a lot of cloth bags were brought from Tongzhou, and the sand was piled up in front of the artillery emplacement, in order to absorb the kinetic energy of the shells, they also made a lot of wicker baskets, loaded sand and piled up in front of the fort.

The main types of artillery in this era are mainly solid shells, and the officers and soldiers are only equipped with a very small number of flowering shells, and the operation of flowering shells in this era is very complicated, and it is necessary to temporarily cut the letter tube to set the shell explosion time, and when operating, it is also easy to have an accident, resulting in an explosion or an explosion as soon as the chamber is discharged, resulting in great casualties to the gunner who operates.

Therefore, even if the officers and soldiers were equipped with a small number of flowering shells, few people dared to use them, and they could only use solid iron bullets or stone bullets for artillery bombing.

The most important thing for these solid shells to play a role is to make full use of the ricochet effect, relying on the shells to bounce up and continue to rush forward after they land, killing and injuring living targets or enemy equipment along the way.

In the current artillery battle, although the officers and soldiers fired a lot of shells, they lost their effect in the face of the well-established artillery positions of the domestic army, and even if individual shells fell in front of the artillery positions, the shells jumped forward, and most of them were blocked by these wicker baskets, sandbags, and mounds of earth, and could not destroy the artillery on the artillery positions.

Unless the shells were accurately smashed into the gun position, it was possible to destroy the artillery of the Yu family's army, so in the face of the inferior artillery skills of the officers and soldiers, the artillery positions of the Yujia army basically did not suffer much loss.

On the other hand, the gunners of the Yu family army are well-trained, have advanced sights, shoot quite accurately, and hit the battlements at all, without any pressure.

Although the battlement wall itself is also very strong, compared with the main body of the city wall, it is far from the old nose, and it is no problem to be a bow and arrow, but it is impossible to block the cannonballs.

As long as the shells are hit, the bricks and stones that have been hit will immediately fall down, and the officers and soldiers hiding behind the battlements will also be unlucky, either they will be directly blown away, or they will be killed and injured by the masonry, and they may even be buried alive under the collapsed masonry.

For a time, the defenders of the city were beaten and screamed, and they were scurrying around the city walls to avoid flying cannonballs and flying masonry.

Gao Qiqian was still personally supervising the battle on the city wall, but when he saw that the artillery fire of the Yu family army was so fierce, he was so frightened that his face turned pale, and he fled off the city wall with his tail between his legs, jumped and shouted under the city wall, and continued to urge the officials and soldiers to guard.

Yu Jiajun's tactics are quite effective, one by one, in the roar of the cannons, knocked off one by one, the originally neat city wall, soon became the old lady's gums, there are gaps everywhere, the officers and soldiers do not dare to stay on the city wall, let alone drill behind the battlements, whoever hides behind the battlements, who may become the next victim, and the battlements are knocked over by shells.

As for the artillery in the city, it was the focus of the Yujia army, and the artillery had special observers to indicate the target to the gunners, and they kept an eye on the city wall, using low-powered binoculars to search every battlement on the city wall, and as long as they found the artillery of the official army, they immediately gave instructions to the gunners.

The gunners immediately followed their instructions and aimed their guns at the positions of the guns, and then fired their guns to destroy them.

At the beginning, the gunners of the official army were still very happy, but it didn't take long for them to find that things were not good, and many of the artillery that fired would soon be bombarded by the artillery of the Yu family army under the city, and after a short time, many of the artillery pieces were destroyed by the artillery of the Yu family army.

Even if they were not directly hit, the cannonballs hit the women's wall, and the splashed bricks and stones smashed the gunners into flesh and blood, and the gunners in the city suffered heavy casualties.

The morale of the officers and soldiers was not high, and after discovering this, many gunners hurriedly stopped firing their cannons, and even hurriedly dragged the cannons back, not daring to let the cannons show their heads again, so as to avoid the shelling outside the city.

Originally, the artillery on the city wall was still quite lively, but in less than half an hour, it was completely dumbfounded, either it was destroyed on the spot by the Yu family's army, or it was so frightened that he shrank back, and he didn't dare to show his hair and the cannon fired back.

After the initial rapid fire, the artillery of the Yu family army completely suppressed the official artillery on the city wall, began to slow down the speed of artillery bombardment, and methodically continued to knock out the battlements on the city wall, flattening many of the battlements and turning them into piles of rubble.

Needless to say, the officers and soldiers suffered a lot of casualties, and the rest either lay on the city wall in a safer place, holding a shield to protect their heads and did not dare to get up, or fled to the city wall, so that there were hardly a few people on the city wall.

The shelling lasted for a whole hour, and at noon, the Yu family army engineers and siege infantry, who had already been waiting for the city, received Yu Xiaotian's order, and then the officers pulled out their swords one by one, raised them high above their heads, and let out a wild cry like a wolf's howl: "Brothers, rush with Lao Tzu!" ”

Countless officers and soldiers of the Yu family, pushing all kinds of siege equipment or carrying many siege equipment on their shoulders, like a tide, swarmed out from their starting place, and under the leadership of countless officers, they only rushed towards the direction of the city wall.

The shouting of killing suddenly resounded throughout the battlefield, like a mountain shouting tsunami, rolling over the entire Jingshi.

At this time, the engineering troops finally came to show their might, although they were not the main attacking force, but they took on the task of opening the passage close to the city wall for the main attacking force.

Yu Xiaotian directly gave up attacking the city gate, because all the outer gates of the Jingshi were built with a strong urn city, even if they attacked the urn city, they still couldn't attack the city, so he simply directly ordered the attacking troops to directly attack the city wall, Pan Cheng went up, and captured the city gate.

Therefore, they had to open a passage close to the city wall first, but it was not a simple task to open this passage.

Because Jingshi as the capital of the Ming Dynasty, is the lifeblood of the Ming Dynasty, all kinds of fortifications are built very complete, plus Chongzhen years, Jiannu entered the customs several times, the first time to enter the city of Beijing, so that Chongzhen is very nervous, but also at the expense of manpower and material resources, after which vigorously strengthen the city defense.

Therefore, looking at the world, there is hardly a city that has such perfect fortifications as Jingshi.
