Today's Yizhou in Liaodong, that is, Yixian in Jinzhou, Liaoning Province in later generations, is located in the northwest direction of Jinzhou City 80 miles, to the west is the border wall of the Ming Dynasty and the Eastern Mongolian tribes, the north is the Daling River, the east is the Yiwu Lu Mountain, the strategic position is very important.

If Dalinghe City is the eastern barrier of the Ningjin defense line, then Yizhou is the northwest barrier of Jinzhou City, and it can even be said that no matter which direction Jianyu besieges Jinzhou City, as long as Yizhou is still in the hands of the Ming army, then Jianguo's back road is not guaranteed.

Of course, if Guangning City is always in the hands of the Ming army, it can also play the role of strategic strategy and containment, and can be used as a horn with Dalinghe City, one as the northern outpost of the Ningjin Defense Line, and the other as the eastern outpost of the Ningjin Defense Line.

The Ming Dynasty's initial strategic layout in Liaodong was like this, with the top at the forefront of the Ningjin defense line, one was Guangning, which was 200 miles away from Jinzhou and went out in the northeast, and the other was the Daling River City, which was built on the west bank of the Daling River 400 miles away from Jinzhou.

The Guangning City of the Ming Dynasty was the Liaoning North Town of the later generations, and the Dalinghe City was the Liaoning Linghai of the later generations.

If it was placed before the Battle of Sarhu, the location of Guangning City was naturally the best choice to control Liaodong militarily, and Liaodong Town at that time was indeed set up in Guangning City.

But now, the cities of Tieling, Kaiyuan, Shenyang, Fushun, and even Liaoyang in Liaodong have fallen, and Guangning City has become the forefront of Liaodong Town's border with Jianyu, and the administrative office of Liaodong Town has to move south to Ningyuan because of this, which is enough to show that the existence of Guangning City has actually become a chicken rib.

Give up, it can't be justified on the face, after all, the abandonment of a city means that the land within a radius of hundreds of miles falls into the hands of the enemy.

But don't give up, a lonely city, standing at the forefront of the border with Jianyu, money, food and materials all rely on Ningyuan long-distance transshipment, often cannot be supplied, and Jianyu comes to besiege the city at every turn.

As soon as Jianyu besieged the city, the army of Liaodong Town had to travel long distances north to relieve the siege, and because Guangning was too far away from Jinzhou, and at the same time too close to Jianyu, so every time the Ming army went north to rescue, it would create countless opportunities for Jianyu to besiege the city and send reinforcements.

In this way, by the time of the Chongzhen period, although Guangning City was in the hands of the Ming army, it actually became a wound that Jianyu constantly bleed to the Ming army.

And this just explains why Quang Ninh City is obviously in the northernmost part of the Ningjin defense line, but it has not been captured by the Houjin army. It's not that the Houjin army can't take it, but that the Houjin deliberately doesn't take it, and uses the tactics of besieging the city to send reinforcements to constantly attract the Ming army to the north and annihilate the Ming reinforcements going north in the field battle. And this tactic has been tried and tested repeatedly.

So did the existence of Guangning City play any positive role in the history of the Liaodong War at the end of the Ming Dynasty? It can be said that there are almost none.

Because Guangning City is far away from Jinzhou, it is difficult to transfer military materials, so there have never been many garrisons, so every time Jinzhou is besieged, or Ningyuan is besieged, the Guangning garrison does not dare to go out of the city to pursue or go south to rescue except for looking at the ocean and sighing.

And the Jianyu army attacked Jinzhou directly every time, and even bypassed Jinzhou and attacked Ningyuan directly. Therefore, if Dalinghe City can still play a certain early warning role because it is blocked by the strategic route of Jianyu to attack Jinzhou to the west, then Guangning City is really a tasteless and regrettable chicken rib when the entire strategic center of Liaodong Town moves south.

In the past, the city of Guangning, which had spent countless money and grain and was repeatedly rebuilt, in addition to becoming the blood loss of Liaodong Town again and again, did not play the role that the imperial court wanted it to play.

Compared with Guangning City, Yizhou, which has not been valued by the Ming Dynasty in history, has been highly valued by Jianyu Huangtaiji, especially after several times through this place detoured to Mongolia and directly entered the hinterland of the Ming Dynasty, the Houjin side realized the importance of Yizhou more and more, and finally occupied Yizhou, and built a strong city in Yizhou, stationed heavy troops.

Since then, the Ningjin defense line has been in turmoil, completely lost the ability to forge ahead, and can only retreat in Jinzhou and Ningyuan to defend, while the Liaodong army not only can no longer advance in the northeast direction, but also loses the ability to contain the Manchu and Mongolian coalition forces from the grassland to attack the hinterland of the Ming Dynasty from the grassland.

Because the city of Yizhou is located in the northwest direction of Jinzhou, it not only effectively contained the eastward advance of the Ming army, but also completely closed the door of the Ming army's westward advance.

Jianyu built a city in Yizhou, and immediately trapped the Ming army to death in the chess game of Liaodong at the end of the Ming Dynasty.

Of course, the current Emperor Chongzhen will not continue to let this happen.

Long before the Jiliao governor Lu Shanji went to Ningyuan to take office, Emperor Chongzhen had clearly told him that Guangning could abandon it, Daling River could be guarded, and Yizhou must be firmly grasped in his hands.

Therefore, not long after Lu Shanji took office, he took his old comrade-in-arms Man Gui, who he had known many years ago, to Jinzhou, Dalinghe and Guangning, and along the way not only inspected the current front-line situation, but also unified his views with the generals of Liaodong Town, such as Man Gui, Jin Guan, He Kegang, Zu Dale, and Jin Guofeng.

In fact, there are many real people of insight in history, who have seen the dilemma of Liaodong Town, and the idea of defending western Liaoning, attacking eastern Liaodong, and withdrawing from Guangning at the same time has always existed.

It's just that the court is clear and the flow is in charge, and the strategy of attacking the east and defending the west has not been implemented in the Apocalypse years, and then at the beginning of the Chongzhen year, Yuan Chonghuan killed Mao Wenlong, and the so-called main attack of Liaodong was no longer mentioned, because Liaodong lost Dongjiang Town, and there was no ability to attack at all.

The western Liaoxi mentioned in the strategy of attacking the east and defending the west refers to the western Liaoning corridor and the Ningjin defensive line, while the eastern part of the Liaoning refers to the Liaodong Peninsula in later generations, that is, the direction of Lushun, Jinzhou and Dongjiang Town.

After taking Man Gui and others around Jinzhou, Dalinghe, Guangning, and Yizhou, Lu Shanji returned to Ningyuan at the end of May, and soon reached an agreement with Man Gui, the chief soldier of Liaozhen, and Chen Renxi, the supervisor of Liaozhen, and others, determined to implement the strategy of attacking the east and defending the west proposed by Emperor Chongzhen as soon as possible, and abandon the rebuilding of Guangning City and Dalinghe City.

It was agreed that with all the money, food, and materials planned by Wang Zhichen and others to rebuild Guangning and Dalinghe Cities, priority should be given to the construction of Yizhou City, and a barrier conducive to defense would be added to the northwest direction of Jinzhou City and the newly established Ulan Hada Command Division.

Lu Shanji's decision-making may be redundant in the short term, but it is extremely necessary in the long run. And this is precisely the reason why some people in the Liaodong Army have different opinions.

After all, the city of Yizhou is also a safe rear, and the city of Quang Ninh and the Daling River, which are on the front line, will not be rebuilt, but choose to spend a lot of money, food and materials to repair the city of Yizhou, which is not a top priority.

Such voices were especially prevalent among the soldiers of Jinzhou, Dalinghe, and Quang Ninh.

But Lu Shanji's personality, once he made up his mind, how could he be affected by some different voices, not to mention that this was a strategy personally explained by the emperor, and after his investigation, he also agreed with such a strategy.

Therefore, when the news of Ning Yuan's mutiny finally reached him on the night of July 27, he was simply shocked and angry. At this time, Lu Shanji was in the city of Yiju.

Since the beginning of June, after Lu Shanji straightened out the personnel relations of the Jiliao Governor's Mansion, especially Liaodong Town, he took Man Gui, his 5,000 cavalry and nearly 10,000 foot soldiers in Ningyuan City, escorted a large number of grain and grass military supplies, and went north to Yizhou.

Of course, while Lu Shanji went north to Yizhou and personally guided the construction of the city, he was also ordered by the emperor to bring the Italian missionary Wei Kuangguo and the Portuguese retired military officer Gao Kaus? Teixeira and more than 20 other Hongmao Xiyi, as well as the ten newly purchased Hongyi cannons that came to Liaodong to settle with these Hongmao Xiyi.

Now, under the guidance of the Italians Wei Kuangguo and Gao Kaus, and through the joint efforts of more than 20,000 soldiers and civilians inside and outside the city of Yizhou, a newly built city of Yizhou with the technology of Westerners is about to be completed, but the news of the mutiny in Ningyuan suddenly came.

After hearing the news, Man Gui, the general soldier of Liaozhen who accompanied him, was naturally furious, and immediately took his five thousand cavalry to the south overnight, but was finally persuaded by Lu Shanji, so he did not set off immediately.
