In the Middle Ages, human productivity was low, but even a little more natural disaster would bring production activities to a standstill.

Disasters do not discriminate against nationalities and races. The snow disaster in the north and the waterlogging in the south correspond to the rainy season in Annam.

Because the dimension of Annam is lower, it is closer to the tropical climate than the Ming Dynasty, so it is hot and rainy all year round. In the 17th century, the infrastructure was sparse, and the rainy season was an out-and-out disaster for the people of Annam.

During the time period of the arrival of the traverser, most of Annan has entered an official mandatory timeout. Under the continuous rain, the people could not go out to work, and the army could not step on the mud to remotely dispatch and assemble. If they are forced, they can quickly become contagious diseases within the army: the warm and humid rainy season is also a time when germs are rampant.

In contrast, the crossing forces, which have a complete logistics and supply system, and even a complete epidemic prevention and medical system, are not very cold about the current rainy season, but are a little welcoming.

Because in this way, although the progress of the project is a little slower, there is no need to worry about external military pressure, and you can concentrate on building turtle shells when you are most vulnerable in the early stage of landing. In this way, the advantages and disadvantages are added and subtracted, and it is obviously earned.

In view of the current situation, Shao Qiang, who was in charge of controlling the situation, issued an order: speed up infrastructure construction, reduce peripheral military investment, and tilt most of the resources to the construction of the Hongji Fort-Hongji Port complex.

The planned third batch of reinforcements has now been suspended and replaced with engineering personnel and construction supplies.

And so it was settled. In the next few months, Shao Qiang, along with other travelers who have come to Hongji, such as Zheng Yangyang, will seize the rare window period to build on a large scale and lay a solid material foundation for expansion and possible military operations after the rainy season.

And Sha Zhengming, who was in charge of the military aspect, also left after the order of Annan County to leave. The current military pressure has decreased, so that Sha Zhengming has time to run back to Guangzhou to report on his work...... There's an important meeting coming up there.

August 1, 1631, Guangzhou New District, the second floor of the Prime Minister's official residence.

The nondescript Prime Minister's official residence has been in use for some time. At first glance, this building is a square building, but if you look closely, the three floors seem to be a little round, probably because the construction period was tight and the technical level was not enough.

It can only be said that the tiger is not an anti-dog.

However, this little awkwardness is nothing to the traverser, at most it is an after-dinner joke. After all, in the crazy development of the past few years, there are too many similar things to be on the hot search.

It doesn't matter, these ugly temporary buildings, including the supermarket version of the palace, will have to be demolished sooner or later.

As for the narrator...... Of course, the Ming people don't understand the stalk of the round oval office, but they are full of admiration for the official residence, after all, the three-story reinforced concrete building is still a rarity.

Those who can enter the rare building are naturally rare people.

Today, the large conference room on the second floor of the official residence was once again full. The high-level leaders of the crossing forces, including the heads of various departments that have been relocated to Guangzhou, were all present.

Among them, the most complete are military people. Sha Zhengming, who rushed back by clipper, was already sitting behind the long table in the outer circle and smoking.

Presiding over the meeting was naturally the owner of the official residence, the first assistant of the empire, Xia Xianze Xia Zhongtang.

The theme of today's meeting is to discuss the battle of the Daling River, which is taking place in the bitter cold land of the Far North and deciding the fate of the Ming Kingdom and the Later Jin Dynasty in history.

When the participants arrived, the first thing to do was a brief introduction to the campaign. The next moment, Wang Xiaohui, who was chubby and dressed in a white admiral's uniform, stood up, walked to the wall and pulled off the flannel, picked up the whip, and explained to the large northeast map on the wall.

The Daling River was called Yushui in ancient times.

The Daling River and its downstream Xiaoling River, which run through the middle of the Liaoning West Corridor, were the transportation hubs connecting the Northeast and the Central Plains in ancient times. Qi's Northern Expedition to Shanrong, Cao Wei's conquest of Wuhuan, Qianyan's entry into the Central Plains, Northern Qi's attack on Khitan, and Sui's and Tang's pacification of Goryeo, all took the Daling River Valley as the main route of the march.

In the northeast situation at the end of the Ming Dynasty, in addition to Lushun, who was alone behind the enemy, Houjin had already occupied most of the territory of Liaodong, including Shenyang.

In this way, Mingguangningwei (Jinzhou), which is at the head of the Liaoning West Corridor, is facing tremendous military pressure. And Dalinghe Fort is in the east of Jinzhou in the later generations, within the jurisdiction of Linghai, a county-level city.

Open the map at a glance, and the location of Linghai City is at the top of the narrow Liaoxi Corridor. After passing through this place, it is the vast land of eastern Liaoning, so the Dalinghe Fort with Jinzhou at its back is undoubtedly the throat of the western Liaoning corridor.

As early as the Apocalypse years, the Ming government and the opposition, which had suffered successive defeats, began to try to adjust the national strategy after discovering that the field battle was not the opponent of the Houjin army, intending to make use of the strengths and avoid the weaknesses, and use the "fort-building tactics" to compress the living space of the Houjin step by step, and lock up the Jiannu outside the pass.

Although it was helpless, this strategy was the only choice of the Ming Kingdom at that time. There is no way, the field battle cannot be fought, and the Ming army lacks mobility and will to fight, so the turtle stream, which can give full play to the advantages of defense and scale, is the only correct choice.

Prior to this, Gao Di, the former governor of Liaodong, considered that the supply line was too far and felt that he could not bear the pressure of Houjin, so he ordered to abandon the Ming army facilities on the Jinzhou line of the Daling River and move the army and the people inside.

After that, after a strategic tug-of-war with Houjin, the fort-building faction gradually gained the upper hand again. During the Apocalypse, Yuan Chonghuan, who was the governor of Liaodong at the time, ordered the Guanning army to go forward after the Battle of Ningjin, trying to restore the two cities of the Great and Small Linghe that had been demolished by the Later Jin Army.

The reason is simple: Dalinghe Fort is too important, regardless of the advantages and disadvantages, it has to be fought for.

If the Ming army wants to consolidate Liao, it must build Dalinghe City, and then Jin will also demolish this city if he wants to attack Ming. Therefore, as early as the era of Yuan Chonghuan's Liao, the competition between the Ming and Jin sides for the two cities of the Great and Small Linghe was very fierce.

However, things are not so simple.

The Houjin attack on Ningjin was a battle far from the rear, and its combat effectiveness and logistical supply capabilities were limited. This is also the reason for the Battle of Ningjin, where the Later Jin army finally retreated from the Jinzhou front.

In the Daling River area, the logistics supply route of the Houjin troops was greatly shortened, and the combat effectiveness was correspondingly enhanced.

On the other hand, when the turtles of the Ming Kingdom flowed to the first line of Dalinghe Fort, they had already reached a critical point, and the marginal effect was reduced. The two sides are at war in this area, and no one is clean. Considering the field superiority of the Houjin army, the Ming side even suffered a loss.

This has been proven by the facts.

The Ming army rushed to repair the Dalinghe Fort twice before and after, but in the end they all returned in vain, and the Dalinghe Fort was repeatedly demolished by the Houjin...... Since it is a choke point, it is also a place of great concern for both the enemy and us. Houjin would not allow the construction of the Great Linghe Fort, which could pose a huge threat to his family.

Time continued to move, and at this point in time in August 1631, the Daling River Fort, located on the banks of the Daling River, once again became the winner and loser of the front confrontation between the Ming and Jin countries.

This matter has to start with the entry of the Jin army into the customs last year.

In history, Houjin entered the customs for the first time, and it can be said that it was a great success. After that, the Ming Kingdom, which suffered huge losses, then organized a counterattack.

How to fight back? Or rush to repair the Dalinghe Fort outside the gate.

Originally, in history, soon after the Houjin army withdrew from Guanwai, Emperor Chongzhen once again appointed Sun Chengzong, an old minister who was old, to supervise the military affairs outside Guanwai, and according to the established policy, sent the main force of the Guanning Army entrenched in Jinzhou to build Dalinghe Fort for the third time.

In the face of the rebuilding of the Ming army, Huang Taiji certainly could not sit idly by. Subsequently, Huang Taiji recruited 50,000 troops, including Mongol soldiers, and set out from Shenyang on August 24, 1631, divided his troops into two routes, and went straight to the Dalinghe Fort that was being repaired.

Due to the short distance between Dalinghe and Shenyang, after just 7 days, the armies of Houjin and Jinlu converged in front of Dalinghe Fort on September 1.

The Houjin army, which had just grabbed a vote from the Ming State and had sufficient logistics, changed its attitude of attacking in the past and carried out a long-term siege of Dalinghe Fort that was hastily repaired.

After that, Huang Taiji adopted the tactics of encirclement and reinforcements, and successively eliminated 4 waves, with a total number of more than 100,000 Ming army reinforcements.

And the Zu Dashou Department, who presided over the repair of Dalinghe Fort, was besieged alive for three months. In the end, after eating up the 20,000 soldiers and civilians in the city, Zu Dashou, who was awarded the title of "ogre", went out of the city and surrendered with the remnants of 10,000 people on November 21.

Ten days later, on December 1, 1631, the Battle of the Daling River ended.

————————————————————————————

When Wang Xiaohui put down the whip in his hand, the traversers sitting in the large conference room also turned around one after another, sat upright, and returned to the posture they should have had when the meeting was held.

The next moment, Xia Xianze, who was sitting at the end of the long table, spoke: "After listening, let's talk about it all and speak freely." Today is already August, and there is a situation about the Daling River in the Northeast, how should we deal with it. ”

As soon as Xia Xianze's voice fell, a voice came out of the empty conference room: "What else to deal with, it's not over watching the show." ”

Everyone turned their heads to see that it was another traverser in a white military uniform who spoke: the commander of the Navy's First Fleet, Mu Longcheng.

Mu Longcheng, who is considered an old handsome guy in the traversal, rests his hands behind his head at the moment, leans back, and has a smile on his face that sees through the world...... He almost rested his feet on the table: "Guan Ningjun and Huang Taiji tore each other apart outside the pass, and by the way, they lost the Ming Field Army in the direction of Shanhaiguan, isn't it a good thing?" What else to deal with. ”

Speaking of this, seeing that the scene was still silent, Mu Longcheng shook his head and made his words clear: "Don't pretend, one by one seems to be really worried about the country and the people, look at your pride...... If you really wanted to interfere, why did you go earlier? Today is August 1st, and Zu Dashou has already begun to repair the city wall, interference, by what interference? Is it in time? ”

Hearing that Mu Longcheng was talking more and more, Army Commander Han Xiaobo interrupted someone's speech after coughing dryly: "Although we can sit on the mountain and watch the tiger fight in the matter of Daling River, it is not that we cannot interfere. The army currently has half a battalion of 300 regular cavalry and 200 training soldiers deployed in Tianjin. ”

"Huang Taiji is carrying 50,000 junior brothers at the door of his house this time, what's the use of your 300 cavalry?"

"It's okay to fight guerrillas and harass them."

Mu Longcheng rolled his eyes when he heard this, and stopped talking.
