Shenyang City was built in the Hongwu period of the Ming Dynasty, and the Liaodong Commander commanded the envoy to command Min Zhong to supervise the construction. During the years of battle between Nurhachi and the Ming army, the Ming city wall of Shenyang was almost completely destroyed except for the north gate. Therefore, the Shenyang city that Dayong sees now was built after Nurhachi and Hongtai, and the pattern of the entire city is also very different from that of the Ming Dynasty, and only the city gate has been repaired by four. They are the East Inner Governance Gate and the Fujin Gate; South Tianyou Gate, Desheng Gate; West Wai Gate, Huaiyuan Gate; Beidi Zaimen, Fusheng Gate.

The names of these eight city gates that make Dayong sound a little awkward are offered by Han officials who have reduced their gold in recent years, and the original name is so close that people feel close, how easy it is to remember the small east gate, the big east gate, and the small south gate.

Mang Gurtai told Dayong that this Shenyang city is divided into inner and outer cities, and the inner city has the Khan's palace built during the Nurhachi period, as well as various large and small Baylor mansions, and in addition, the six yamen of the Jin State that was just established last year are also in the inner city. The outer city is where the Shenyang banner people and the Mongolian and Han people live, it is very chaotic, but the population is large, there are nearly 100,000 people, but most of them are Han people who are slaves.

Although there are many Han Ahabs, Mang Gurtai thinks that Dai Shan will not levy these Han people to go to the city to help in the war, and his biggest possibility is to levy those left-behind bannermen in the large and small Baylor Mansions, in addition to more than 100 soldiers in the Khan's palace. If Dai Shan sent the Han people to the city to help in the war, then he would have to worry about whether there would be people who would open the city in civil strife like Dajin attacked the Ming city back then.

Buying Han spies to set fire to the city, snatching the city gate This trick was played by Nurhachi a lot, and it worked repeatedly, followed Nurhachi to fight for many years, Mang Gurtai heard about it, and personally operated it a few times, so he firmly believed that Dai Shan would not do this stupid thing, although the Ming army did not buy the Han people in the city, but how did these Han people come to this Shenyang City, I am afraid Dai Shan must take into account. Among these people, how many of them have no blood feud with Dajin, and a few of them are willing to continue to be ruled by the Jin people when they see the Ming army attacking!

As for how many defenders Dai Shan could piece together, the figure given by Mang Gurtai was three thousand, which was not a small gap from Wu Heyin's previous estimate.

Wu Heyin also told Dayong on the side that after the Jin people set the capital of Shenyang, in order to prevent the Ming army from coming back one day, they not only built Shenyang City very firmly, but also most of the artillery captured from the Ming army over the years were placed at the head of Shenyang City, with no less than 100 large and small artillery. Mang Gurtai also agreed on the sidelines.

When he heard that there were 100 large and small artillery, Dayong was really taken aback, but he immediately didn't care.

Nurhachi and Hong Tai inadvertently did Dayong a great favor, in order to make the so-called capital of the Dajin Kingdom look particularly magnificent, under the guidance of a feng shui master, on the basis of the original Ming Shenyang City, four city gates were added, and eight main streets were built in the city, the so-called "eight gates to eight streets". This kind of pattern naturally makes Shenyang City wide and tidy, and can accommodate no less than 100,000 people at once, which is very suitable for a small country to be located at the beginning of Xingding, but the problem is that these eight city gates inadvertently share the strength of the Shenyang defenders.

In the past, the Jin army won consecutive battles, and took an offensive against the Ming Dynasty, so that the Ming army outside the pass was out of breath at all, burning incense and worshiping the Bodhisattva begging the Jin army not to come to fight them, where did they have the courage to fight the Jin army, let alone Shenyang City.

Even if the Ming army had the courage to attack Shenyang, it would first have to cross the hurdles of Guangning and Yizhou, and if these two cities were not taken, it would be impossible for the Ming army to march straight into Shenyang. It's a pity that after so many years, not to mention Guangning and Yizhou, even the Ming army of the Linghe River, which is only a few dozen miles away from Jinzhou, has not been able to step through, and has spent countless money, food, and manpower to play the game of I build you and demolish it with the Jin army.

Therefore, although Hong Tai and the high-level officials of the Eight Banners knew the shortcomings of the guards of Shenyang City, they never took it to heart, in their opinion, it was better to worry about the Ming army attacking Shenyang than to worry about how many Han Ahas would freeze to death this year.

Now it's okay, something that Hong Tai never dreamed of has happened, in the gap between him leading the army to conquer Mongolia in person, Shi Dayong, who had let him run into a bloody head under the fortified city of Jinzhou, actually killed him from southern Liaoning. A pig-killing knife slashed hard and quickly on his soft flank, a fatal soft flank, but the owner of the pig-killing knife was completely mistaken, and the reason why he decided to cross the sea was just to take advantage of the fish in the name of Kong Youde. God knows how big Shi Dayong's fish is, he did what no one did until the fall of the Ming Dynasty, and did what Mao Wenlong wanted to do but didn't have time to do.

Whether it is the 3,000 defenders estimated by Mang Gurtai or the 5,000 proposed by Wu Heyin, it is not enough for Shenyang City, which has eight city gates. The Ming army can launch an attack at any city gate, but it is impossible for the Jin army to concentrate the main force somewhere, and can only divide the guards, otherwise he can only temporarily transfer troops everywhere to fight fires.

In the same way, more than 100 artillery pieces sound like a lot, and it is really unbearable for the Ming army to be put in one place, but how much lethality can be left on the eight city gates. The artillery captured from the Ming army over the years is not the Hongyi cannon made by Portugal, but the cannon with serious quality problems supervised by the Ministry of Industry of the Ming Dynasty. And Mang Gurtai also gave Dayong a reassuring pill, he told Dayong that in fact, the Jin army did not have much gunpowder, nor did it have the ability to make its own gunpowder, and the gunpowder when attacking the Daling River last year was actually purchased by Hong Tai and Tong Yangxing from the merchants of Daming Shanxi at a heavy cost, and this bit of gunpowder was almost used.

Mang Gurtai affirmed that if the artillery at the head of Shenyang could fire three rounds, he would be killed by a head-on.

Mang Gurtai's assurances made Dayong overjoyed, since those artillery were good, they could immediately attack the city when the artillery arrived. You don't have to make any siege equipment, just attack the city gate.

In fact, Dai Shan had already made a move of a strong man to break his arm when he deployed Shenyang's defense force, and the number of defenders he deployed in the outer city was only 1,000 unarmored bannermen and 3,000 Han Chinese Aha who could be trusted. And the more than 1,000 armored soldiers he could really rely on, together with the Khan's palace, and the remaining 2,000 bannermen were all deployed in the inner city.

Outside the city, Dai Shan didn't want to defend it at all, and he didn't have the confidence to keep it. If it was only the Ming army, Dai Shan might still be able to launch a battle against the army and people in the whole city and fight to the death with the Ming army, but the existence of Mang Gurtai made him dispel this idea, because it was impossible for Mang Gurtai not to know the true situation of Shenyang City, as long as he told the Ming General that Shenyang was actually not enough to defend the army, then it was a matter of time before Shenyang City was broken.

More importantly, Mang Gurtai is the owner of the Zhenglan Banner, although he was cut off the title of Da Beile and took away his Niu Lu, but there are many bannermen and Aha who belong to him in Shenyang City, and there are many people who sympathize with and support him, most of these people live in the outer city, once these people respond to Mang Gurtai, it will undoubtedly be a catastrophe in Shenyang.

Mang Gurtai has been the big Baylor for so many years, who knows how many people in Lu Dao secretly colluded with him. The emaciated camel is bigger than the horse, and after Mang Gurtai fled, although Dai Shan ordered the arrest of the officials and generals related to Mang Gurtai, it was impossible to kill them all, and if he did so, it would only exacerbate the uneasy commotion caused by Mang Gurtai's defection. Just as Dayong did not sacrifice the butcher's knife for the sake of a stable Liaoyang City as the rear, Dai Shan also needs to temporarily spare some people he wants to kill but can't kill for the sake of a stable Shenyang.

The decision to focus on the outside and the inside is the result of the joint discussion between Dai Shan and Adun, Yanguli, Dudu, Yilintai, Sony and other civil and military forces who stayed in Shenyang.

The inner city is where the Dajin military and political center is located, the city wall is built stronger than the outer city, and there is only one city gate, easy to defend and difficult to attack, concentrate the elite to hold on to the city, as long as it is guarded for seven or eight days, Dai Shan believes that he can see the banner of the main force of the Eight Banners.

In order to appease the people who were disturbed by the rebellion of Mang Gurtai and the arrival of the Ming army, Dai Shan ordered to allocate money and grain from the household department to reward the bannermen who participated in the defense of the city, and selected the best weapons from the arsenal of the military department to send them to the city. After the Ming army arrived at the south bank of the Hunhe River, the pontoon bridge that has been more than ten years old was renovated again, and then began to approach the city of Shenyang, and after arriving closer, they shot arrows into the city, and the arrows that were shot into it were tied with a letter, and the owner of the text was not Shi Dayong, the commander of the Ming army, but Mang Gurtai.
