Different from the initial attack after the army had just completed the siege and assembly under the city, the attack launched by the army besieging the capital on the 29th day of the old calendar in the second year of Chongzhen was obviously no longer an average test of the reality, but more concentrated. Eighteen Hongyi cannons with 3,000 catties of body tubes were distributed in the two directions of the tunnel and the earthen ramparts, concentrated on the city gate, the range was no more than ten zhang, the distance was only about a mile, and the relatively dense arrangement was carried out under the guidance of the Western gunners, and the pressure of the attack obviously began to change a little.

The continuous firing made it seem that the defenders inside the city gate had no respite to rebuild the earthen ramparts and civil fortifications, and hundreds of large and small general guns also began to fire continuously with higher charge standards and heavy shotguns while using wooden fortifications to strengthen the barrels to prevent explosions. The Anding Gate, which had already become sparse, was filled with projectiles flying sideways for a while. Especially with the help of the east wind that is common in summer, the billowing smoke is also approaching.

With the help of heavy fire and the cover of smoke screens, a real assault on the city gates began. This time, it was no longer the cannon fodder used for testing, but at least a few thousand soldiers who were barely able to fight, although there were not enough iron armor to arm, but everyone at least had a decent shield holding an iron sheet. At the same time, it was not all melee soldiers, and many of the attacking team also carried guns that were already loaded with ammunition and ready to shoot at close range.

The large and small general cannon with the strengthened charge also launched a projectile attack with heavy shotgun in the direction of the inner side of the Anding Gate with heavy firepower, spanning a distance of about one mile. Although the stray bullets spread over such a distance, especially when it was difficult to find targets in the city, the fierce artillery fire in the own army still had a slight encouraging effect on the attacking team.

Almost at the same time, more officers and soldiers on both sides of Andingmen began to hold shields, and under the supervision of the warlords, they collectively approached and approached the distance of the projectile, and began to shoot arrows like rain on the city continuously, and the artillery fire that approached closer and began to open fire. Obviously, if you want to reduce the pressure of attacking the city gate as much as possible, then the direction of the attack should not only be the city gate itself, but also include the area of at least one stone's throw on both sides of the city gate. The scope of suppression is not only the head of the city, but also within a certain distance and range of the inner side of the city.

In the case of a rain of bullets and arrows, although the defenders could still avoid their own casualties by preparing civil fortifications and tunnels at the head of the city as much as possible, the attack below the city head and even the arrangement of troops began to face huge problems.

In the age of firearms, it is true that the effectiveness of many siege engines was greatly reduced due to the possession of many means such as 10,000 enemies and even heavy artillery, but on the other hand, the superior firepower of the attacker also brought great pressure to the battlements. Especially when the siege of the capital this time was not an ordinary peasant army that was only good at field warfare and lacked artillery, but a border army in the northern regions equipped with a large number of firearms and artillery.

Seeing that the suppression of the city seemed to be going well, Cao Wenzhao couldn't help but smile and said: "Look at the legendary Son of Heaven forbidden brigade is indeed only good at field warfare, and does not know how to defend the city. This kind of turtle tactics that are unwilling to invest real capital and unwilling to pay too many casualties will only make us likely to directly occupy the head of Andingmen during the day today... ”

Under the cover of artillery fire, within a range of nearly two miles or so, tens of thousands of troops engaged in the attack and hundreds of ladders composed of cloud ladders also began to approach the entire Andingmen, as if intended to force the defenders to show their heads to resist, otherwise the attacking team is likely to break through the entire city on a large scale.

As expected, when the heavy artillery fire caused the continuous battlements on the head of the real city to begin to be bombarded, and the defenders on the head of the city were more and more exposed and could only resist on their stomachs, the siege of the city under the city began to begin.

At this time, only a small number of 10,000 enemies or thunder stones and even fireballs thrown by stone throwers were thrown from the city, as if the entire defender army was not a city defense team of the Ming Dynasty, but from the Spring and Autumn Period and the Warring States Period, there were not many means of defending the city at all.

Therefore, thousands of Ming troops easily launched the final attack on the city along the connected ladders, and continued to attack the city. Under the suppression of the powerful artillery fire and bullets of the besieging side, the defenders within two miles of the assault seemed to have fled, and basically gave up the city to a large extent.

The army that was constantly attacking the city seemed to see only the defenders of the city, and it seemed that they had built earthen walls about the same height as the city walls, but only slightly shorter, on the inner side of the city. At the top of the earthen wall, it appears to be the top of a traditional siege engine, with only the seemingly narrow shooting gap exposed. Even if there were many shooters there, it seemed that the firepower was not enough to pose much threat to the Ming army, which had achieved a full-scale siege breakthrough within two miles.

However, at this time, the firepower that was as fierce as the top of the car shattered many people's illusions. The 20 teenagers who had gathered at the top of the building car and were divided into two rows to fire firepower fired more than 200 rounds of projectiles in a very short period of time just through the more than 200 three-two bullet firearms that had been filled under the top of the building car long ago, and the seven or eight building cars that had been deployed within two miles fired 1,000 rounds of heavy ammunition in a very short period of time. The light muskets were quickly thrown into the net that had been prepared long ago, and more than 200 firearms men completed the loading with the help of the cover of the city wall as quickly as possible, and continuously sent them to the top of the building car to concentrate the fire to the maximum.

If it was in the era of cold weapons or the early Ming Dynasty, when firearms were immature, this tactic obviously had great limitations. Because projection power that can effectively break through defenses is scarce, melee combat is the decisive combat force, and this practice may be covered by the armor and shield bearers who ascend to the top of the city and gradually build up an effective defense at the head of the city.

However, when the era entered the sixteenth century, and individual firearms capable of piercing shields and armor began to appear, everything seemed to be a little different.
