On the afternoon of June 28 of the old calendar of the second year of Chongzhen, 27 Hongyi cannons transported from Liaodong and Shanhaiguan began to bombard the capital gate from all directions in a group of three. With the help of the Sunset Missionaries, only about half of the previous charge could maintain a decent hit rate after continuous test firing at a distance of about one mile, and almost every Hongyi cannon with three guns fired two rounds of fire with a high probability of one shell hitting the city gate, and sometimes as many as two. At a distance of about one mile, the hit rate for the city gate is almost as high as about 20%.

In this way, in just an hour or so, about thirty or forty rounds of salvo fire were fired, and the nine gates of the capital from the outer gate of the urn city to the inner gate seemed to be easily opened under the fierce artillery fire, and even some of the fortifications that could be seen in the inner gate and even the high walls that were built collapsed under the fierce artillery fire.

"Is it going to attack after nightfall, or is it tentative to attack now?" In order to prevent possible accidents and even evade responsibility, Mao Wenlong at this time still had reservations and asked Yuan Keli and even Sun Chengzong, who was nominally responsible for leading the troops. Obviously, the defenders' practice of not sealing the city gates, especially the inner city gates, seems to be able to directly let the attacking side see that the practice of many fortifications deployed in the city is too strange and has a bit of an empty city plan.

Sun Chengzong finally gave the order to launch a tentative assault during the day before nightfall: "Let the general army prepare for the attack on the Nine Gates, even if it fails, it may be able to find out the reality of the defenders." There is no need to invest too elite backbone capital, so that the soldiers who are barely worthy of the war will not have too much cost to supervise the battle rush to the front, and the firearms and artillery men can prepare shields and firearms to be responsible for pressing the formation... ”

Although Sun Chengzong still has some experience in army building, he still has many shortcomings in leading troops. Seeing this dangerous situation, many of the general soldiers and battalion officers below were not only reluctant to let the backbone elite take risks, but even the ordinary soldiers who were barely worthy of battle were unwilling to be consumed in the first temptation, so most of the people who were engaged in the attack were temporarily recruited in the process of the army moving south. Except for the retreating shield cart in front and the very heavy shields in the back, these people not only did not have decent armor, but even their weapons were only a few short spears that were only suitable for fighting in complex environments.

In this way, if the cannon fodder who is overseen in the battle backshit, it will not give much loss to the person in charge of pressing the formation. If you can still maintain discipline and attack forward, you will be able to use the car shield and the heavy shield you carry to have some basic protection and attract the opponent's firepower.

The projectiles and arrows that came down from all directions on the head of the city were mostly blocked by the heavy shields, and although there were some larger-caliber live ammunition that kept flying in and caused flesh and blood or casualties, on the whole, it seemed that the teams that were not of high quality could barely keep them moving. The armored soldiers who were responsible for the tentative attack were not only responsible for supervising the battle, but also began to cover with relatively sophisticated shotguns, turtledoves, and even cannons, which for a while made the rubble fly between the battlements. The cannonballs that came from behind also made the city instantly dangerous, and the shattered fragments on the city gate tower also fell one after another at this time.

Although some defenders tried to drop thunder stones or other defending equipment from the top of the city, which also caused some casualties among the attacking team, it did not seem to stop the tentative offensive actions launched by Ding Zhuang, who had a total of more than 20,000 temporary recruits in the nine directions of the nine gates.

As the sun set, when the light seemed to begin to dim a little, the fierce sound of artillery fire suddenly sounded in the city, making Ding Zhuang, who was pushing the car shield and even carrying the shield, involuntarily curl up and cover his whole body.

The heavy artillery at the gate of the inner city launched firepower, and the muzzle of the cannon concealed in the civil fortifications was almost about seventy or eighty paces away near the inner city gate and fired directly at the outer city, accurately blasting more than ten pounds of shells into the car shield, bringing many casualties and screams. When only a moment later, the sound of cannons rang out, and it seemed that there was not only one cannon guarding near each of the city gates, although the casualties suffered by the forwards responsible for the siege were not very large, but some began to waver, and they threw down their shields to retreat, and some simply planned to surrender to the defenders in front. However, whether it is the person who runs forward, or the person who shoots backwards, these people are greeted only by the heavy fire of the light artillery that fires shotguns, and many people subconsciously stop when they see that they seem to have fallen into a desperate situation of death, but it seems that because the firepower of the battle is more fierce, they still subconsciously rush forward, at least, it seems that rushing to the city gate can at least have a chance to surrender?

Of course, the Ming generals in charge of the attack had long expected such a result, and did not expect these tentative offensive forces to easily break through the city gates with urn cities, the purpose was only to make these attacking cannon fodder turn into corpses under the city gates. In this hot summer day, where it is likely to rain at any time, as long as there are many corpses that are beginning to decompose at the gates, there is always some hope that the plague will spread quietly, and if so, it will obviously be a clear blow to the morale of the defenders.

As night fell, it seemed that it was no longer appropriate to continue the siege. This is especially true when the defenders can easily drop lighting and ignition from the top of the city, exposing the attackers from outside the city and achieving a certain degree of unilateral blow. At least from the experience of siege warfare in history, there are some advantages and disadvantages for both the attacker and the defender, but it is clear that there are more constants for the attacking side, especially in terms of psychology and mentality. Only by investing in the real elite backbone for gambling, maybe there will be a slight effect.

Although the attack lasted from dusk until dawn the next day, and tens of thousands of corpses were densely gathered in many places from the outer city to the inner city, no one really broke through the fortified area inside the inner city gate defended by the artillery barriers.

When the sky brightened again on 29 June, even Tian Xiuying and others, who did not have a lot of experience in defending the city, understood that the attack of the army outside the city, which had just been assembled yesterday, would obviously not be comparable to that of yesterday.
