In the main hall of the inn, the camp's conference hall, Zhao Bing and a group of escort officials gathered on the sand table, marking the situation between the two sides with red and blue flags. However, the current confusing war made everyone confused and unable to figure out the context, so naturally they did not dare to mobilize their troops without authorization.

"Your Majesty, General Tian sent back the news from the front line of Liangxiang that the Mongolian Yuan has been increasing troops from the Wanping camp, and there are cavalry cruising in the lower reaches of the Lugou River, as if looking for a crossing the river. His judgment was that he wanted to detour behind the Liangxiang camp, trying to seize Liangxiang to break the blockade of our army, and requesting to mobilize troops to block the attack!" Xu Wunan hurried in and reported.

"Your Majesty, the Mongol Yuan has been increasing troops to Liangxiang and sent heavy troops to attack Tongzhou and Tanzhou. This is almost all his troops. Do they want to fight our army at any cost?" Lu Xiufu said in confusion.

"At present, there is no battle breaking out in Juyongguan around the capital. I think the enemy's abnormal movements in Tongzhou and Tanzhou are all feint attacks, intending to restrain the forces of the two camps of Tongzhou and Tanzhou. Only Liangxiang is a real attack, and it is intended to open a path to the northwest. In this way, the enemy can not only escape from the frontier, but also go back to the side and back of the Huailai camp, and attack Ni Liang's troops with the defenders stationed in Juyongguan, completely eliminate the threat from the side and back, and communicate the connection with the grassland." Jiang Yu pointed at the sand table with his finger.

"Well, Jiang Xiang's words are reasonable!" Jiang Jin nodded, "Our army's Huailai camp and the Tanzhou camp seem to be only a hundred miles apart, but there are obstacles from mountains and rivers, and there are natural dangers occupied by the enemy. It is difficult to reinforce each other. The Tongzhou camp is even further apart and dare not act without action. In this way, Ni Liang's troops fell into an isolated and helpless place, trapped under the enemy's attack!"

"The officials thought that the enemy attacked Liangxiang Daying and Tongzhou Daying, intent on forcing the two armies to retreat, expand the depth of defense, and reduce the threat to Dadu. Once the two armies are broken, they can directly threaten the Zhuozhou camp, and the Shengjia was forced to retreat south. Jizhou was also exposed to its attack, threatening the maritime terminal and cutting off our army's food route. In this way, the encirclement of Dadu was suddenly lifted!" Xu Wunan raised objections.

"Can there be a new battle report be sent back to the Tanzhou direction?" Everyone has their own opinions and their own reasons, but they cannot make a conclusion based on this for the time being, Zhao Bing asked again.

Zhao Bing knew that the Mongol Yuan was at a disadvantage and this was contrary to the way of using troops. There must be a conspiracy, whether to attack the east and west, or to surround Wei to save Zhao, transfer the tiger away from the mountain, or simply to escape from the shell. However, based on the current information, he could not make an accurate judgment for the moment, and if he made a decision in a hurry, he might have fallen into the enemy's plan. If he watched the change, once the enemy broke through, it would be possible that he would lose all the money.

"Your Majesty, since the news of the attack was reported in the early morning, no new war reports have been reported. The situation of the war is currently unknown!" Xu Wunan replied.

"Please consider whether the main attack direction of the Mongol Yuan was Tanzhou?" Zhao Bing pointed at Sha Pan with his finger, and then explained, "At present, there is no war in the north entrance of Huailai. Can this be imagined that the enemy will secretly transfer the army stationed in Juyongguan to Tanzhou. Only by seizing this place can the threat from the rear be eliminated!"

"Well, your Majesty's words are very likely!" Lu Xiufu pondered for a moment, "Tongzhou has been occupied by our army and cut off the road to Tanzhou. If the enemy wants to use troops in the direction of Tanzhou, they can only mobilize troops from the city or Changping, and go to the old land of Deru. However, it is difficult to mobilize the army from the city to hide the spies sent by our dynasty, and they can only mobilize troops from the army stationed in Juyongguan!"

"Yes, our expeditionary army can seize Tanzhou. We can reach the capital to the south and reach the south entrance to the west. If the south entrance is lost, Juyong will be in name only. Only by defeating our army in Tanzhou can the threat be eliminated." Jiang Zhen said, "In addition, although our expeditionary army can be used to fighting, its troops are less than 20,000, and we have to divide our troops to stay on Yongping Road and defend against the enemy from the north. There are only more than 10,000 troops to fight. However, it mainly fights foreign wars, relying on the navy to provide firepower support. The headquarters lacks heavy artillery and the support firepower is weak. In the eyes of the Mongol Yuan, it is a weak brigade that can be controlled."

"Does the pseudo-Emperor of the Mongol Yuan want to escape?" Deng Guangjian, who was beside him, had always listened more and said less to such meetings. At the beginning of today, he suddenly interrupted as he listened to everyone's argument.

"Escape?! What did Deng Xiang think of?" Everything he did now was based on guesses. They had never figured out why the Mongolian Yuan suddenly launched a counterattack and what was its purpose. Deng Guangjian's words can be said to be another guess, Zhao Bing turned his face and asked.

"Your Majesty, Tanzhou has always been called the "Youzhou Key". It can reach Liaodong to the northeast, and go north to Gubeikou to the Shangdu. Most of the capital has become a besieged city, and the pseudo-emperor is also a turtle in the jar. Staying in the city is like sitting and waiting to die. As long as you break through the grassland, the tiger enters the mountains and forests, and the dragon returns to the sea, you can deal with our dying with the vast areas of the south of the desert, the northern desert, the Shaanxi-Gansu-Gansu-Law and the Liaodong. The purpose of this battle is to open up this road of life!" Deng Guangjian said.

"What Deng Xiang said can verify the purpose of the Mongol Yuan battle, and it also determines the direction of the attack!" Jiang Qi nodded.

"That's true, the most important thing at the moment is to quickly observe the battle situation in Tanzhou so as to make arrangements!" Zhao Bing saw that everyone had basically reached a consensus and confirmed the enemy's main attack direction. However, the most difficult is that communication is completely based on the legs of the commander's soldiers, and the horses under his seat are not allowed to achieve instant communication, and it is difficult to re-allocate troops if the situation is unclear.

Of course, this is not because of Zhao Bing's indecision and over-prudentiality, but because of the actual situation, there is nothing we can do about it.

First of all, the ancient Tanzhou did not only refer to the modern Miyun area, but governed large areas in northern Beijing, and had been changed throughout the years, and the place name was changed many times. Tanzhou was established in Youzhou during the Kaihuang period of the Sui Dynasty, with its capital in Yanle; in the first year of Wude in the Tang Dynasty, it was changed to Tanzhou, and it was moved to Miyun, which belonged to Beiping County; in the first year of Tianbao, it was changed to Miyun County. In the first year of Qianyuan, it was changed to Tanzhou, which led to Miyun and Yanle.

In the Five Dynasties, the Later Tang Dynasty was in charge of Yanle County. In the Later Jin Dynasty, Tianfu was in charge of Khitan, and was under the jurisdiction of Daoxijin Prefecture in Nanjing, which was in charge of Miyun and Xingtang. In the Jintianhui year, Tang County was abolished, Tanzhou was in charge of Miyun County, and was under the jurisdiction of Zhongdu Road Shunzhou. Genghis Khan occupied Jin Shangdu, re-established Tanzhou, and governed Miyun. Later, it was adjusted and incorporated into the surrounding areas.

However, during the Warring States Period, modern Huairou County belonged to the Yuyang County set up in Yan State. It was hundreds of miles away from the well-known "Yuyang Genggu" in Jizhou. The place name was also changed several times. During the Western Han Dynasty, this place occupied an important position in economic, military, and ethnic exchanges. The court set up iron officials in Yuyang, cast agricultural tools, weapons and manufactured Wuzhu coins, and continued to fight with ethnic minorities in the Yuyang area and sent heavy troops to garrison.

In the first year of Wangmang's founding, Yuyang County was changed to Tonglu County, and Yuyang County was changed to Deyu County. During the Eastern Han Dynasty, Emperor Guangwu pacified various military forces in the north and established the Eastern Han Dynasty. Tonglu County was again called Yuyang County, and Deyu County was again called Yuyang County. After the Wei Dynasty, the strategic position of Yuyang County gradually declined. The Western Jin Dynasty formally abolished the Yuyang system, and Huairou belonged to the Yan State.

During the Sixteen Kingdoms, although the name of Yuyang County was restored, it moved to Wuqing, Sanhe, Sui, Tang, and Jinji County today. Yuyang, located in Huairou, no longer existed. In the Sui, Tang and Yuan dynasties, Huairou never formed an independent system. However, Tanzhou governed a large area from Gubeikou to the northeast of Dadu, which is much larger than the current Miyun area.

Changes in place names and administrative planning in ancient and modern times often made Zhao Bing, who came from the modern times, feel confused, and those civil officials liked to hang books and bags, often quoted ancient place names and county honours, which made him often make jokes. And he liked to read guerrillas in ancient and modern times, and he had to make notes often to avoid making mistakes in military affairs. After all, if you make mistakes, it may lead to a big mistake that the same place name in ancient and modern times is a thousand miles apart.

What Deng Guangjian said is also right. Tanzhou is currently at the intersection of Yanshan Mountain and the North China Plain. It is an important gateway to North China to Northeast China and Inner Mongolia. It is surrounded by mountains on the east, north and west sides, with undulating peaks and gentle peaks in the middle. It has clear layers and is divided into three different regions: deep mountains, shallow mountains and plains. The ancient north entrance under its jurisdiction is the key point to the outside of the Northeast.

The Gongchen Gate of Tanzhou was originally the east gate of the north wall of Liaoning, and it was the only gate to Nanjing to Tanzhou. Merchants sold goods from outside the frontier to Nanjing. Inside and outside the Gongchen Gate were the main activities of merchants in Tanzhou. The prosperity of commercial trade has become a stable commercial base in the capital. It is precisely because of this long time that Tanzhou has been transformed into a local name in Nanjing.

After the Mongolian Yuan built the capital, they had to go to Shangdu to escape the summer heat every year, thus repairing the chariot road. The chariot road entered the capital from Gubeikou, Tanzhou. Therefore, a large number of stations and stations were set up along the way, and soldiers were sent to garrison in dangerous places, thus becoming a place that military strategists must fight for. Now the North entrance has been blocked by the imperial guards of the Song Dynasty, and Gubeikou has become the only way for Tiemur to escape.

"Your Majesty, I think the expeditionary army is weak and the news is cut off. When observing the Ming military situation, I should send reinforcements to avoid being attacked by the enemy!" Jiang Jin suggested at this time.

"With that being said, the closest to Tanzhou is the Tongzhou camp, and they are in a row and they are in a hurry and can't take care of themselves. Where can I draw troops from?" Jiang Xu frowned. As the deputy minister in charge of military affairs, he knew that due to the lengthening of the front line, the troops of each group were stretched, but the camp still took over the cavalry belonging to various combat groups as a combat reserve team, and now he can send mobile troops. However, he was worried that the time was not ripe to mobilize the reserve team when the battle situation was still unclear.
