On the third day of the outbreak of the battle, more detailed reports were sent back to the camp. The spies from the Bureau of Affairs also used various relationships to find out the general context of the incident. It turned out that the outbreak of the war was the product of mutual compromise between the two factions of the Mongolian and Han sects in the Mongolian and Han dynasties.

The two Mongolian and Yuan factions were arguing whether to defend Dadu or retreat to the grassland, and the Khan Tiemur was also hesitant. However, when the Song army approached day by day, cut off the road to leave the capital and completed the strategic encirclement of Dadu, the nearest distance was less than a hundred miles away from the city, which was equivalent to pointing the muzzle at its forehead.

Under this circumstance, the two sides formulated a plan to open the transportation line outside the Great Wall, which satisfies the Han and French factions' idea of ​​"guarding the city, cooperating inside and outside, and annihilation of the enemy's city", and also satisfies the strategy of the kings of the Grassland Sect to "do things to do, retreating outside the Great Wall, and making a comeback", which naturally fits the idea of ​​the Great Khan Tiemur.

After obtaining the approval of the Khan, under the leadership of the old minister Antong, the Privy Council and the Ministry of War formulated combat plans and strictly kept them secrets. Before the battle started, even the generals participating in the war were not aware of it, and even concealed the omnipresent Bureau of the Song Dynasty, which led to the fact that it could not get any news in advance, let alone a detailed combat plan.

This plan is based on the timing of sending troops, the breakthrough points selected, the mobilization of troops, and a series of deceptions. The plan was formulated in hindsight, which was quite meticulous and wonderful. It caught the Song army off guard. When the battle was fully launched, it was even impossible to understand the intentions of the Mongolian and Yuan dynasties.

First of all, in terms of opportunity, the Song army is in full swing and has an advantage in strategy and tactics, and it is inevitable that it is arrogant. And as winter goes and spring comes, it reduces the impact of the soldiers in the southern region on combat in the severe cold climate. With the opening of sea transport and canals, combat and daily necessities are transported to the front line. After Lian Zhan wins, morale is in full swing and underestimating the enemy, thinking that the Mongols will not dare to fight.

Secondly, the breakthrough point is also very good. Tanzhou is a transportation hub to Gubeikou and Liaodong. Gubeikou and Juyongguan confront each other east and west, and is the main road from the North China Plain to the Inner Mongolia Plateau. It has been called a dangerous and dangerous place since ancient times. It is known as "the earth is tied to the dark desert, and the sky is left to lock the key to the strong pass". It is also a must-fight for military strategists throughout the ages. As long as Tanzhou is recaptured, they can communicate with the outside world.

The Song army stationed in Tanzhou had the least garrisons in four directions. Although the mountainous terrain was not conducive to cavalry conflicts, it also restricted the use of Song's weapons. There were as many major passes on the defense line, which stretched for dozens of miles. It can be said that the lines were long and the troops were arranged scattered, which gave the Mongolian Yuan the possibility of concentrating their troops and defeating them one by one, and even if there were casualties, they were still under the burden.

Again, Tanzhou is relatively isolated compared with the Song army camps. The closest one is the Yulin Camp in the northwest, but Juyongguan is separated. If you want to reinforce, you have to break through the natural danger. Therefore, the only one who can reinforce Tanzhou is Tongzhou, but the two places are also 150 miles away.

Even if the Song army could accurately determine the situation and send troops to reinforce, when the Tongzhou camp was also attacked, it would be difficult for them to mobilize troops when they were too busy. Take a step back, under the Song army system, the main general must obtain the permission of the camp to mobilize the army, but it will take time to go back and forth. It will be a few days before the reinforcements arrive, and then Tanzhou has already changed hands.

In addition, the deception of the Mongol Yuan was very successful. They attacked from all sides, disrupting the sight of the Song army, making it impossible for them to judge the main attack direction of the Mongol Yuan in a short period of time, so they did not dare to mobilize troops to reinforce them without authorization, and to capture Tanzhou and break the blockade in the northeast to win time.

In terms of military mobilization, the Mongolian Yuan did not move any soldiers in the city, but chose to transfer troops from the Juyongguan defenders, concealing the battle attempt, which made the Song army's deployment unable to make early warnings. The military mobilization was carried out at night, and it was hidden at dawn, blocking the surrounding areas and strictly prohibiting personnel from entering and leaving, and even the generals leading the army did not know where to go.

The preparation of combat materials was also carried out quietly. The Mongols did not recruit husbands and transport them, nor did they dispatch large troops to escort them. Instead, they used caravans to transport materials to the front line. Tanzhou has always been a key place for north-south trade communication. Caravans would not attract attention. Even if they were a little abrupt during the war, it was not surprising. After all, smuggling has always been the most profitable...

"Your Majesty..." After the war broke out, the camp became busy. From the emperor to the ministers, they were all confused. They were sleepy and took a few bites nearby when they were hungry. After the news came back, the situation of the battle gradually became clear, but after learning about Li Zhen's death, the emperor was often a little distracted. Xu Wunan sent the latest battle report. Seeing that His Majesty had no reaction, he reminded softly.

"Oh, you said!" Zhao Bing looked at him as if he woke up from his dream.

"Your Majesty, don't be too tired, take a break!" Lu Xiufu understood that after learning about Li Zhen's death, his majesty suppressed his grief, but he still couldn't hide his heartache. He looked at the absent-minded emperor and persuaded him.

"Yes, Your Majesty also needs to take care of the dragon body and not be too sad, especially when the war continues, don't hurt your body!" Jiang Jin also advised.

"It's okay, I'm fine!" Zhao Bing waved his hand, rubbed his face again, and signaled Xu Wunan to continue.

"Tongzhou Camp reported that the offensive of the Mongol Yuan slowed down today and did not mean crossing the river. It seemed that there was signs of withdrawal. Deputy Envoy Han thought the judgment made by the camp was correct, and he used feint attacks to restrain our troops." Xu Wunan said, "This morning, the 12th Army had been ordered to set out to reinforce Tanzhou. The entire army was light-equipped, carrying only weapons, ammunition and three-day food. It marched at a fast marching speed and would arrive at the battlefield tonight."

"Liangxiang Daying reported that the Mongolian Yuan side took advantage of the night to escape from contact with our army and intended to retreat. After being discovered by our scout, General Tian ordered a pursuit and the enemy was defeated. This morning, our vanguard had crossed the Jinkou River, captured Lugou Bridge, and the troops were at the foot of Wanping City." Xu Wunan presented the two pages of the battle report for everyone present to circulate it.

"Tian Zhong is very keen. He seized the fighter's opportunity and brought us one step closer to Dadu. Han Zhen was still a little conservative and ordered him to launch a counterattack at the right time to seize Daxing. What do you think?" Zhao Bing quickly browsed it again, looking up to ask others for opinions.

"Your Majesty, I think it is feasible. This will prevent the enemy in the city from acting again!" Jiang Zhen said.

"Your Majesty, I think this will stimulate Meng Ting and make them attack Tanzhou at all costs in case of fleeing north!" Lu Xiufu said.

"Will there be any news to come back to Huailai?" Zhao Bing didn't say anything, and pondered for a moment and asked again.

"Today, the commander of Ni Dutong sent a letter to him, saying that there was no abnormal movement on the surface of the enemy guarding Juyong Pass, but a scout went deep to spy on it. Although the camp was fired at night, there was no smoke from cooking for many days. I think there was an army mobilization, so the details needed to be explored again!" Because there was no road between Huailai and the camp, the war report required a detour for many days, but the stations arranged by the Affairs Bureau can be used to transmit emergency military information with the flying pigeon.

"Although I don't know the details, it can also be confirmed with other information. The enemy troops attacking Tanzhou this time are from the enemy troops stationed in Juyongguan!" Zhao Bing nodded and said.

"In this way, Juyongguan has empty troops, so we have an opportunity to take advantage of it!" Jiang Yu immediately responded.

"Yes, although Ju Yong is in natural danger, he has no gaps in his time of lack of troops. As long as he breaks through a little, he will collapse on the whole line!" Zhao Bing attacked heavily on the case.

"Not bad!" Jiang Zheng also said.

He also knew that the canyon where Juyongguan City was located was located in the mountains of Taihang Jundu. It was surrounded by mountains and hills in the west, with huge streams and cliffs under it. The terrain was extremely dangerous, easy to defend and difficult to attack. It was known as the most powerful pass in the world. There was Guangu for more than 30 miles in the middle of the Guancheng. The city walls were built with stones on both sides according to the mountain, and military troops were arranged to watch and wait. During the war, a large army was stationed in Shanggong. Therefore, it required a large number of troops to defend Juyongguan.

Now that the troops guarding Juyong Pass have been withdrawn in large quantities, it will inevitably lead to a shortage of troops on the walls on both sides, making it difficult to cover everything. Although the mountain is steep and difficult to climb, it is not unattainable. If the soldiers who are good at climbing choose the weak points of the enemy, attack a wall in the dark night, open the breakthrough point to lead the army to the wall, the defenders at the bottom of the ditch will become meat on the pedestal, and the city will be destroyed without attacking.

"Your Majesty, I want to take this battle to launch an early attack and attack the city passes around the city. The troops will be besieged by the city and trap the enemy?" Lu Xiufu asked in a daze.

"Yes, the fighter plane has been shown. We must seize it and must not miss it!" Zhao Bing nodded and said.

"Your Majesty, should you think carefully again? Don't let the army be spontaneously because of a moment of anger and mislead the national affairs!" Lu Xiufu thought for a while, and he was worried that His Majesty would launch a military force in order to rush to revenge, which would lead to failure.

"Prime Minister Lu, I... Although I have lost the general, I will not be confused or misleading the state affairs. Therefore, it is a crime that is unforgivable!" Zhao Bing knew that he was kind and was worried that he would act irresistible, but he could only shake his head and smile bitterly.

"Since Your Majesty has decided, you should make good plans and not be too hasty!" Lu Xiufu said relieved after hearing this.

"Since this is the case, I think that the Tanzhou side should temporarily suspend the counterattack, but instead pretend to be dissatisfied, and redirect the reinforcements to choose a different place to defend themselves, so as not to find clues and withdraw their troops. We will find nothing at that time!" Jiang Jin said.

"If our army retreats blindly, it will lead to the enemy's mistakenly thinking that our army has been defeated and no longer regards himself as Yongguan to send troops to reinforce, thereby increasing the difficulties for the Ni Dutong?" Jiang Yan raised objections.

"Well, you must naturally put a long line in fishing. Don't be too hasty. You can take a lunch break before discussing and make a detailed plan!" Zhao Bing nodded and said.

"Yes, I will leave!" Everyone felt that they had to think calmly, then make a conclusion, and stood up to bow and leave.

"Your Majesty, this is the detailed process of the death of Sima Li, who was sent back by the expeditionary army. Please read it and mourn me!" Seeing everyone leaving, Xu Wunan took out another memorial from the file and presented it to the top...
