The siege of the city was not as smooth as imagined, in fact, it was not unexpected by Mao Wenlong and even Cao Wenzhao and others. As a strong force in the field, how could it be so unscrupulous when defending the city, and it was broken through on a large scale on the first day of the attack? Of course, there will be some aftermath and preparation. In the view of Cao Wenzhao and others, who have some experience in military affairs, especially in the defense of cities in the Liaodong area, this may be a means for the defending side to save troops and material resources. Because it has strong combat power, it is not necessarily afraid that the besieging side will attack the castle. When the battlements were almost completely damaged by massive artillery fire, it was obviously more economical to fire back at the besieging side's superior projectile fire against the heavily defended opponent under the city than to fire at more than one of the same earthen platforms on the inside of the city walls. This tactic is difficult for ordinary armies to emulate, but it may not be impossible for the Forbidden Brigade of the Son of Heaven with strong archers and gunners to follow suit. It's just that Cao Wenzhao didn't expect that the reserve defense on the inside of the city wall was just a defensive platform like seven or eight steps of building cars within two miles.

"Orders to the armies! Go on the offensive! Now that the opponent's artillery has not yet been revealed, and the obstacles outside the city have been resolved, let the ladder cart be set up and ready to attack! Cao Wenzhao ordered.

In the age of firearms and artillery, things such as building carts were the most dangerous for the attackers in the traditional siege equipment. However, the volume area does not seem to be huge, but the survivability of the ladder truck, which can be set up at any time to attack, is obviously much stronger. With the defenders not having much decent resistance from the city, and the obstacles outside the city were filled by the massive attacking force, thirty ladder carts that had been prepared for a long time were soon carried side by side on the top of the city, becoming a smooth road leading to the top of the city with a width of dozens of paces. The elite forces that had already been prepared in the true sense of the word also began to hold a rare iron shield under the heavy reward, wearing decent iron armor, covering the team, skillfully began to attack the city. Although there were sporadic sporadic stones that smashed from inside the city, it was obviously not a threat to the besieging side that was ready to attack.

Yuan Keli also couldn't help but look down on the party responsible for defending the city at this time: "Since ancient siege warfare, although the besieging side often needs more casualties and troops, if the defending side does not have the courage to fight to the death at the risk of bullet attacks and casualties on the city, it will definitely not succeed... ”

As Yuan Keli and others expected, although the side defending on the inner side of the city wall prepared the inner earthen wall and the building cart as a means of counterattacking under cover, but in the face of the elite soldiers with heavy shields who followed the ladder car to the top of the city, the deterrent effect was greatly reduced, at least the effect of side shooting was not so good. Even if you can rely on fierce momentum to defeat a few people on the other side, you can't stop the steady stream of reinforcements. After the layers of shields formed a battlement-like cover with the help of crouching armor soldiers, the shotgunners and three-eyed gunners who attacked the city also began to use firearms to shoot at the fire points of the building trucks that were not too far away.

The gunners of the firearms battalion, who had been prepared for a long time, also began to carry some of the second or third general's tiger guns to the base of the city as quickly as their own troops occupied the city, and of course there were many heavier shields with brackets. Denser and denser defenses were formed over the entire city. Although the Ming troops who climbed to the top of the city were relatively poor in their ability to threaten the defenders with light artillery and even some very rudimentary firearms, they also seemed to have formed a relatively solid defense on the top of the city.

"Since the opponent's defensive focus has been pinned down by the continuous offensive strength of our army, let's start according to the prepared plan!" Yuan Keli, who was personally responsible for directing the siege operation, ordered.

Just when the Ming army gradually occupied the heel outside the Anding Gate and attracted more and more defenders from the farther direction of the city, the Ming army, which had long been ready to attack in the direction of Chaoyangmen in the east, concentrated more than 500 large and small general cannons to launch a fierce bombardment, and in just a few minutes, thousands of shells fired from ten rounds of red turned the battlements within 200 steps into incomplete, so that the defenders on the head of the city could only retreat to both sides through the trenches that had been prepared for a long time. Almost at the same time, the ladder trucks under the cover of the tall car shields also erected their frames and began to attack.

Although there seemed to be more resistance at the head of the city than near Anding Gate, and many of the attacking troops were killed or wounded by explosive firearms such as 10,000 enemies when they approached the city, it seems that the defenders of the city were too weak and easily attacked the city. The relatively successful operation near Dongzhimen also triggered the climax of the first Ming attack. Because only a few people waited to go up to the city, perhaps it could be explained by luring the enemy deeper. However, the various performances of the defenders at this moment are obviously the result of insufficient arrangements for troops and combat power.

In this way, more and more Ming troops broke through the seemingly tall city, and a steady stream of foothold in the distance of at least four or five miles near Dongzhimen and even Andingmen, at least more than 10,000 main forces of the Ming army attacked the city. If it weren't for the existence of a high wall along the inner side of the city wall, there would have been street battles in the city and even other city heads from all directions. When the defenders seemed intent on attacking elsewhere along the city's head, they finally met with what seemed to be decent resistance. Relying on the covered tunnels on the head of the city to shoot various general cannons, as well as some artillery guns deployed in the city, the focus of the attack was on preventing the enemy troops waiting for the head of the city from further attacking along the city wall, so that the temporary mobilization of those who were not very elite on the head of the city Ding Zhuang barely stopped the attack of the Ming army. However, it is clear that this confrontation situation is quite fragile, as the Ming army outside the city continues to put the real elite archers into the city, the balance seems to be completely broken near dusk, Andingmen and Dongzhimen in the two directions, the Ming army controlled the city head gradually expanded from about four or five miles to a range of about ten miles, and the number of troops on the city head has also increased to as many as 20,000.

At this time, Yuan Keli, who felt a little uneasy, also ordered the team waiting for the city to make use of the original fortifications and tunnels on the city head to be covered and prepared with heavy shields, and at the same time, some less elite forces also began to temporarily retreat from the city to reduce the density of troops, and prepare for the possible counterattack of the defenders at night.
