The evening breeze at the end of April was extremely cool, but the heart of the old general Wuding Marquis Guo Ying was extremely hot, he stood on the hill, paid close attention to the situation in the valley, and issued orders from time to time for the people around him to carry out. He must ensure that nothing goes wrong, after experiencing the decisive battle of Mobei in the last year of Hongwu and the pursuit of the Daning army in the early years of Jianwen was ambushed twice, Guo Ying could feel the young emperor's distrust of his ability, which made him very distressed, but also helpless, so when he learned the news of the Mongols' entry into the pass, he planned this campaign, intending to solve the problem of Yongping, Zunhua, and Xifengkou in one fell swoop, encircling Beiping from three sides, and cutting off the back road of the Mongol army.

To complete this plan, Guo Ying must get Geng Xuan's support, because entering the customs to participate in the war is within Geng Xuan's authority, not within his authority, and the emperor's order to him is to wait for the opportunity to seize Daning and Kaiping, and block the back road of the Mongol army. However, he believed that this plan was too conservative and did not have much effect, and even if Kaiping and Daning were captured, it would not be able to prevent the Mongol army from retreating. But if the Great Wall can be controlled, it is possible to wipe out the Mongols.

After careful consideration, Geng Xuan agreed to this plan, but this plan was only known to Guo Ying, Geng Xuan, Gai Yu and Wu Sheng, and they did not even tell Zhu Yunwen because they were not sure of success. The key point of this plan is Jiang Yu.

Jiang Yu is a very inconspicuous little person in the Yan army, he was the commander of Zunhuawei when he surrendered to the Yan army, and now he is still the commander of Zunhuawei, although Jiang Yu's ability is ordinary, but he is very knowledgeable about current affairs. He sent his eldest son Jiang Chenglong to Yanwang's Mansion as a guard, which set a precedent for protons, and other generals had to follow suit, so Zhu Di was "Longyan Dayue", so he trusted Jiang Yu very much.

But Zhu Di never thought that this Jiang Yu would betray him, as early as soon after the Battle of Baoding, the people of the Investigation Department contacted Jiang Yu, and Jiang Yu then leaked a lot of information to the Investigation Department, including the news that the Mongols were stationed in Zunhua and were preparing to attack Sheng Yong. The Investigation Department attaches great importance to Jiang Yu and promises to ensure the safety of his son, and Jiang Yu's news is also absolutely confidential, only Zhu Yunwen, Wang Du, and Liu Jing know about Jiang Yu's situation in the court, and other than that, Ping'an, Sheng Yong and Geng Xuan, even Xu Huizu doesn't know.

When Guo Ying learned about Jiang Yu's situation, he was ecstatic, so he planned this plan, but he also knew very well that as long as this plan started, Jiang Yu's exposure would be a matter of time, so he could only succeed and not fail.

Fortunately, the Battle of Baoding and the Battle of Tongzhou greatly deterred the Yan army, and the entry of the Mongolian army not only exposed Zhu Di's lack of self-confidence, but also caused many people to be dissatisfied. The abandonment of Xifengkou Pass has caused dissatisfaction with the Great Wall Pass, and the Mongols are in and out of the Great Wall at will, so what do they need these guards to do? Therefore, these fortresses entered a state of inaction at the same time, and even the guards of Lengkou and Jielingkou also threw themselves into the imperial court.

Therefore, when the Mongolian army went south, Geng Xuan went out of Funing and Shanhaiguan, while Guo Ying took 5,000 cavalry and 5,000 infantry out of Lengkou and ambushed near Miaojiaao, and Jiang Yu's plan to lure the enemy into an ambush was also Professor Guo Ying's. Jiang Yu needed a day to prepare, in fact, it was mainly to inform Guo Ying and let him come quickly.

When Guo Ying led his troops to arrive, the fate of Li Rang and Tim Legen was doomed, and they encountered flanking blows from the head and front and back in the narrow valley, and collapse was inevitable.

Looking at the Ming army cleaning the battlefield in the valley, occasionally mixed with a reluctant scream, Legen pondered for a long time, looked back at Jiang Yu, and said with a wry smile: "General Jiang Yu, it seems that you have made the right choice, this Yan King is hopeless, but I can't betray the young leader, he is as kind to me as a mountain, as you Han people say: 'Death for a confidant!'" 'But he wants to die, and he will never betray. ”

Jiang Yu chuckled, pointed to the bottom of the mountain and said, "Then General Cowardice, do you think that without your help, we can't capture Zunhua or Xifeng Pass?" ”

"This," Timlegen smiled bitterly: "You have such a powerful firearm, and you are also the commander of Zunhuawei, if you are caught off guard, whether it is Zunhua and Xifeng Pass, it is within easy reach for you." ”

"Then what are you hesitating about? Isn't it good to throw yourself at me Daming? ”

"Although the Ming Kingdom is good, it is not my hometown, my home is in the Xihai Grassland!" As he spoke, he took a deep breath and turned to face the north: "If General Jiang can read it for the sake of our acquaintance, please give it a good time." ”

Jiang Yu shook his head and sighed: "Okay, after cleaning the battlefield, our army will return to Zunhua overnight, if nothing else, you can control Zunhua and Xifengkou Pass tomorrow, before that, General Guo will inevitably behead you, I hope you can think about it!" ”

"Well, thank you General for the reminder, but I've made up my mind!"

Jiang Yu patted the cowardly Legen on the shoulder, turned to Guo Ying and said, after Guo Ying heard it, he just nodded lightly, indicating that he understood.

The next morning, Jiang Yu led the troops back to Zunhua, the Mongolian cavalry in Zunhua was caught off guard, and was annihilated by Jiang Yu and Guo Ying, and then Guo Ying carried the tiger squat cannon to attack the Xifengkou Pass, the Mongols were not good at defending the city, and they would not use many city defense equipment, so before it was dark, the Xifengkou Pass had fallen, and the remnants of the army fled to Kaiping with the remnants of the Eseku and Wang Xing.

Looking at the Xifeng Pass behind him, Eseku howled and cried, can his father Ugqi come back? The Klergut division was hit hard by this, its strength was greatly reduced, and there was no longer an advantage in the four divisions of Warat, what should I do? Is the Klergut Ministry going to disappear into the wind?

Wang Xing next to him persuaded: "Young leader, there is no other way now, we can only return to the Klegut Department immediately, take advantage of the opportunity of the other three leaders within the Great Wall, immediately send troops, annex the three Warat tribes, and unify Moxi, in order to compete with the Golden Family." In addition, if my expectations are correct, the gold family will not lose less than us, and we still have a chance. ”

"But," Eskuku hesitated, "if we go, won't my father be alone?" ”

Wang Xing didn't answer immediately, and after a while, he said in a deep voice: "As long as the great leader can get out of the Great Wall alive, then no one dares to touch him, and if he can't get out, then no one can save him." ”

When Eseku heard Wang Xing's cold words, he couldn't help but be stunned, and after a moment, he looked to the south in pain and shouted, "Father! Then he fell to the ground, Wang Xing hurriedly dismounted, tried his breath, and ordered the guards to carry the young leader on his back, day and night, back to the West Sea.

After Wu Sheng returned to Yongping with the captives, he immediately reported to Geng Xuan, and after Geng Xuan, Gai Yu, and Wu Sheng discussed, Geng Xuan decided to attack the city immediately, of which Wu Sheng was in Beiping, Geng Xuan was at the east gate, and Gai Yu was at the south gate. Wu Sheng first sent someone to shout, informing him that the reinforcements had been wiped out, and let people carry Li Rang's head to show the public, and finally drove the captives to attack the city.

Under the siege on three sides, civil strife broke out in the city, and finally Guo Liang killed the main general Liu Jiang Kaicheng and surrendered.

At this point, the Battle of Yongping ended. Geng Xuan suffered only 5,000 casualties, then captured Yongping City, captured more than 10,000 people, and was known as the "Yongping Great Victory" in history.

After capturing Yongping, Geng Xuan did not stop, sending troops to recover Luanxian, Leting, Changli, Funing and other places, and at the same time sent troops to reinforce Zunhua and block the retreat of the Mongolian army.

On April 29, Zhu Di was shocked when he learned the news of the loss of Zunhua and Xifengkou Passes, and immediately discussed countermeasures with Ugqi.

On April 30, Zhu Di learned the news of the loss of Yongping, Luanxian and other places, but he looked up to the sky and sighed, unable to save him.

The news reached Beiping, and the morale of the Ping'an army under the city of Beiping was greatly shaken, and Sheng Yong ordered to increase the siege of the city, trying to break the city within five days; The city is like a mourner, and the morale is greatly declining, but under the strict orders of Zhu Gaochi and Zhu Neng, they can barely hold the city.

Under this prestige, the Great Wall Fortresses contacted Ping'an and Guo Ying one after another, and returned to the imperial court, and Ping'an and Guo Ying appeased them one by one, ordering them to tightly control the fortress and prevent the Mongols from jumping over the wall.

After more than half a year of fierce fighting, the rebels are declining, and the situation of counterinsurgency is very good.
