Sun Chengzong's exploits in Liaodong can be described as mixed, and some people praise him for building the Ningjin defense line to withstand the Houjin Iron Cavalry, so that Nurhachi and Huang Taiji could not advance an inch; Some people criticized him for using huge military funds to build useless fortresses, not only did not recover Liaodong, but laid the foundation for the capture of Zu Dashou and Hong Chengchou.

Sun Chengzong's merits and demerits in Liaodong will not talk about him for the time being, because it is all the affairs of the Chongzhen Dynasty, and now it is the Chongzheng Dynasty, he no longer has to bear the responsibility for the loss of Liaodong, and it is impossible to lose Liaodong in the Chongzheng Dynasty!

As early as November of the second year of Chongzheng, Zhu Cijiong ordered Sun Chengzong to take advantage of the main force of Huang Taiji to detour through the Mongolian steppe to attack Jingshi, and sent people to attack Guangning, and the result was really to recover the entire territory of Guangning without much effort.

Now that more than a year has passed, Quang Ninh has been run by him like an iron bucket, and he no longer has to worry about being beaten back by Houjin, he can't help but look ahead again.

Sun Chengzong's Liaodong strategy can be summed up in four words, that is: fortress advancement, as for whether this fortress advance is right or not, it is really difficult to evaluate now, because the Ningjin defense line was not broken by Houjin, but given to them by Hong Chengchou and Wu Sangui.

If you want to use the fortress to deal with the cavalry, there is absolutely nothing wrong with this method, the cavalry is not good at attacking the city, and you can only kneel when you run to attack the fortress after you are known as the invincible. But war is not a matter of wishful thinking, and it is not necessary to storm the fortress to win, and others can not attack it.

Why not win without attacking? Let's sell it here, let's talk about what Sun Chengzong is doing now.

If Sun Chengzong's tactics are more popular, they are: repair the bunker, repair the bunker, repair until you have a headache, repair until you vomit blood, and repair until you have to attack my fortress!

Now he is naturally building a fortress, Chongzhen Dynasty during this period Zu Dashou was sent by him to repair the Linghe Fort, but was surrounded by Huang Taiji for three months, the food was exhausted, and he had to surrender and escape.

The inertia of history is amazing, and it was Zu Dashou who was sent to repair the bunker at this time, but this time it was not the Daling River Fort on the Daling River, but the Shuangtaizi Fort on the Shuangtaizi River.

Dalinghe Fort is located near Jinzhou, which is now Jinxian County, and now that Guangning has recovered, there is no need to repair the Dalinghe Fort behind. Shuangtaizibao is now the Shuangtaizihe District of Panjin City, which is the first stop from Guangning to Shenyang.

At that time in the Chongzhen Dynasty, the Ming army was short of food and few people, and even the main force had to go to Tuntian, and the Ming army that could run to Dalinghe Fort was less than 50,000, and they had to do it themselves to repair the city wall; The current Ming army is full of soldiers, and there are about 100,000 troops that can be mobilized, and the thieves in the northwest are constantly escorted over, and they don't even need to repair the city wall themselves.

50,000 people are working hard to repair, and there are 100,000 people on the side to help, the progress of the city wall can be imagined, and when Huang Taiji received the news, the city wall was almost repaired!

Dalinghe Fort only circled dozens of miles, and the Emperor Taiji jumped angrily, and immediately went to attack, but Shuangtaizi Fort went in a circle for hundreds of miles, could he not go!

And Sun Chengzong's goods are addicted to repairing bunkers, if you don't care about him, he can repair bunkers all the way to Shenyang!

At this time, Huang Taiji had imitated the lighting system to form six departments, including officials, rites, households, soldiers, criminals, and workers, and the heads of the six departments were all young Baylor, who were directly under the leadership of Huang Taiji, and Huang Taiji was steadily advancing on the road of consolidating power, and the power of the four major Baylor Daishan, Mang Gurtai and others was further weakened and weakened.

Huang Taiji was in need of a big victory to justify his centralized power, and the construction of this Shuangtaizi Fort could be said to be at the right time, and he immediately requisitioned a large army after receiving the news, preparing to attack Shuangtaizi Fort.

This time, Huang Taiji recruited nearly 100,000 troops, including the Mongolian cavalry, and on July 27, the fourth year of Chongzhen, he set out from Shenyang and crossed the Liao River on the next day, opening the prelude to the battle of the Shuangtaizi River.

When Sun Chengzong heard that Huang Taiji was coming, he immediately ordered Zu Dashou to lead 40,000 horses to stay in Shuangtaizi Fort, and the remaining 60,000 horses were stationed in Xiping Fort and Zhenwu Fort behind, and Shuangtaizi Fort was a horn to resist the attack of Houjin.

Sun Chengzong thought that Huang Taiji would be like in the past, stupidly ran to attack the city, the mines had been buried for him, under the city wall of Shuangtaizi Fort, the inner three layers and the outer three layers were full of mines, and the grenades were also prepared for him, and the 40,000 horses under Zu Dashou almost every man had a grenade, as long as Huang Taiji ran to attack the city, he would call him crying dad and calling his mother!

Is Huang Taiji stupid? Of course, Huang Taiji is not stupid, not only is he not stupid, but he is also very smart, every time he fights, he is very strategic, and all kinds of strategies emerge in endlessly, he is an out-and-out wise handsome.

Like the first time he attacked the Beijing Division, he first ambushed between Santun Camp and Zunhua, preparing to sneak attack the Shanhaiguan defenders who supported Zunhua; and then arranged an internal response to take advantage of the chaos to sneak attack Zunhua; Then he went straight to the Beijing Division, wanting to mobilize the Ming army to follow his baton. If he hadn't met Zhu Cijiong, a demon who came through and could predict the prophet, he would have been able to defeat the Ming army that time. In the Chongzhen Dynasty, he could use the same method to ambush and kill Zhao Shujiao, the chief soldier of Shanhaiguan, and capture Zunhua and all the nearby cities, and also killed his henchman Yuan Chonghuan!

Such a smart person, after knowing the power of cannons and grenades, naturally he will no longer run stupidly to attack the city, he changed his tactics this time, called: encirclement and reinforcements.

He first ordered Beledeg, Yuetuo, and Azig to lead 50,000 troops, detour to Shuangtaizibao, and then camp between Xiping Fort and Shuangtaizibao to cut off the connection between Shuangtaizibao and the Ming army. Then he led an army of 50,000 to dig four trenches around Shuangtaizi Fort, and built a wall more than one zhang high, surrounding a small Shuangtai Fort like an iron bucket.

The Ming army never expected that Huang Taiji would make such a ruthless move, the ancestor of the city was startled, he made several tentative breakthroughs, and was killed by Huang Taiji. Fortunately, now Daming has a lot of money, and the army usually carries a month's worth of grain and grass, otherwise he would have gone crazy.

When Sun Chengzong heard that Huang Taiji was doing this, he was so angry that he almost didn't have a mouthful of old blood spurting out, he just didn't want to fight a field battle with the Houjin Iron Cavalry when he built the fortress, this is good, you either don't go to the rescue of Shuangtaizi Fort, if you want to rescue Shuangtaizi Fort, you must fight a field battle with Huang Taiji!

There are 40,000 Ming troops and 50,000 people in Shuangtaizi Fort, how can they not be rescued, Sun Chengzong had no choice but to order Guangning General Army Mangui to leave 5,000 men and horses to guard Xiping Fort and Zhenwu Fort, and the remaining 50,000 horses and horses gathered to rescue Shuangtaizi Fort.

This is the evil of Huang Taiji, he not only hoarded 50,000 horses between Xiping Fort and Shuangtaizi Fort, but also hid forty self-made Hongyi cannons!

Man Gui is also a fierce man who can't be more fierce, he is not a civilian official, nor is he a hereditary general, but he is killed step by step from a small soldier, he himself doesn't remember how many enemies he has hacked and killed, and he is also the first soldier in the battle, and he rushes forward without his life.

At that time, Chongzhen Dynasty was because he was too fierce, and when Huang Taiji attacked Jingshi for the first time, he actually led the army to hedge with the Houjin Iron Cavalry, and as a result, he was full of wounds in the first battle, and the soldiers were defeated and killed in the second battle.

Although this time it was not the defense of the Beijing Division, he also did not escape the fate of being wounded in the first battle, as soon as he led the army to rush up, he was stunned by the Hongyi cannonball, and then Derge, Yue Tuo, and Azig led the army to rush up, and surrounded him is a slash, and he was cut all over with wounds.

Fortunately, Xiping Fort is not far from the battlefield, Man Gui ordered the whole army to quickly return to Xiping Fort as soon as he realized that something was wrong, and he himself took his own guards to break in the back, which avoided the tragedy of the annihilation of the whole army, and the Ming army that finally fled back to Xiping Fort was less than 30,000 people, and the Ming army suffered heavy casualties in this battle!

The news came back to Shanhaiguan, Sun Chengzong knew that something bad was wrong, Huang Taiji actually hid Hongyi cannons in the army, even if he sent all the defenders of Jizhou Town, Shanhaiguan and Ningyuan, he might not have done Huang Taiji's 100,000 army!

What to do? It was impossible for Zu Dashou not to rescue him, and Sun Chengzong had no choice but to send someone to report to the Beijing division and ask the emperor for help: Your Majesty, didn't you say that you were building a new type of artillery? Why don't you send a hundred doors to the Liaodong Army first, Huang Taiji ambushed dozens of earthen cannons, and almost killed the general soldier Mangui!

Zhu Cijiong received the urgent report, his nose was almost crooked, and he said in his heart: "Huang Taiji, Huang Taiji, can you not be so fucked up, I just thought about discussing with Sun Chengzong how to clean you up, and you came to the door, can't you give people some time to prepare?" I'll die in a few months! ”

Of course, he is not a god, just a god stick, it is impossible for Huang Taiji to be read away by him after reciting a few words in his heart, if he wants to make Huang Taiji retreat, the only way to do it is to go up with a real knife and a real gun.

If you want to say that now is really not a good time to fight with Huang Taiji, the northwest side is at a critical moment, this howitzer has just been built thirty, and the recruits have just started training, what should I do, let 150,000 recruits go up and do it? What are you kidding, the Houjin Iron Cavalry under Huang Taiji is not a peasant rebel army, and if you send recruits to work with others in less than a month, it will be simply a food delivery, and it may be wiped out by others in minutes.

Zu Dashou had to be rescued, although it was said that Zu Dashou finally surrendered to the Manchu Qing Dynasty at that time in the Chongzhen Dynasty, but Zhu Cijiong did not have much opinion on him. Hong Chengchou, Zuo Liangyu, and Wu Sangui all surrendered without a fight, shameful! But this ancestor Dashou is different, he really had no choice but to surrender, and he really can't be blamed.

Like the battle of Daling River, Zu Dashou led 30,000 Ming troops to defend the lonely city, and the food was exhausted, and there was only four or five days of food in the city, but he held on for three months, and finally he surrendered because he couldn't bear it, and it was a fraudulent surrender!

If you only have four or five days of food, how can you hold on for three months? This is a tragic, tragic and even miserable scene, Zu Dashou's loyalty is second only to those who would rather die than surrender, and it can even be said that he is worse than those who would rather die than surrender!

How did Zu Dashou rely on four or five days of food to hold on for three months, it was very simple, he would eat war horses without food, and he would eat ...... without war horses, not to mention, anyway, in the end, Zu Dashou couldn't stand it, so he went out of the city and surrendered, at this time there were only more than 10,000 hungry Ming troops left in the city, and other Ming troops and civilians were ...... It's gone.

In any case, it is impossible for Zhu Cijiong to let such a tragedy happen again, he was about to make a desperate bet and send only 50,000 elite Beijing battalions, but Xu Guangqi came to ask for a meeting.
