On February 8 of the second year of Jianwen, the sun was setting.

At the head of Baoding City, Chen Xuan, Meng Shan, and Li Jun are watching the fierce battle under the city, from their point of view, Ping'an's Chinese army is facing away from them, and Ping'an is coming down from the high platform, and the 20,000 infantry around him are moving forward, preparing to reinforce Wu Jie on the left flank, and the vehicle array on the right flank is also moving to the left front, preparing to attack Xu Neng and Zhang Wu's cavalry, and between Zhu Di and Zhu Neng, is Song Xuan's 20,000 cavalry, Song Xuan ordered Lin Tianmu to lead 5,000 cavalry to intercept Zhu Neng, and he took the remaining cavalry to attack Zhu Di; And Zhu Di ordered Xue Lu to continue to attack Wu Jie, and led his troops to attack Song Xuan.

Now is at a very delicate moment, if Zhu Neng can quickly defeat Lin Tianmu, then Song Xuan's belly and back will quickly collapse when the enemy is on his back, and then 40,000 cavalry will press Wu Jie together, even if Ping'an reinforcements come up at this time, it will be useless, Ping'an will inevitably be defeated, the infantry will inevitably be annihilated, Ping'an can only keep a small number of cavalry at most, and flee in the wilderness; But if Lin Tianmu can withstand Zhu Neng, Ping An can support Wu Jie in time, and Liu Sui's car formation can reinforce Lin Tianmu in time to intercept Zhu Neng, then Zhu Di's cavalry will be encircled and annihilated, and once Zhu Di is killed, the war will be over.

At this time, in fact, Ping'an has a better choice, which is to order the 5,000 cavalry staring at the south gate to send out reinforcements to Song Xuan or Lin Tianmu, as long as they can prevent Zhu Di and Zhu Neng from converging, then they can win.

Ping'an looked back at the head of Baoding City, and then looked at Lin Tianmu, who was retreating step by step in the fierce battle, it was too late for the infantry to step forward, and they could only rely on cavalry.

Ping'an gritted his teeth, and finally decided, he ordered the last 5,000 cavalry to reinforce Lin Tianmu, and divided his 20,000 infantry into two parts, 10,000 forward, and 10,000 backward to put up a defensive formation to prevent the city gate from rushing into formation.

Chen Xuan carefully observed for a while and ordered: "Beat the drum and shout 'King Yan will win!'" 'Quick, quick! Meng Shan and the others gave the order, and the thunderous drums and the tsunami-like "King Yan will win" immediately sounded on the city. When the sound of drums and the sound of "King Yan will win" reached the battlefield, the Ping'an army, whether cavalry or infantry, slowed down, turned to look in the direction of Baoding City, and the morale-boosting Yan army took the opportunity to storm, and the Ping'an army retreated step by step, and it was about to collapse.

Ping'an was furious when he heard this, and immediately ordered: "Beat the marching drum, and give another signal to order the defenders of the large camp to beat the drums at the same time!" At the same time, he shouted 'Kill Yan, Gonghou Wandai!' ’”

The drums and shouts of killing under the city quickly suppressed the drums and shouts at the head of the city, the Ping'an army stabilized its position, Morgen's 5,000 cavalry reinforced Lin Tianmu, temporarily withstood Zhu Neng's offensive, and Liu Sui's car formation, Ping'an's infantry continued to advance, as long as they were in place, Zhu Di and Zhu Neng would be in danger.

But at this moment, the drumming of the camp suddenly changed and became rapid. Ping An Jian raised his eyebrows, wanting to be angry, but Huo Ran turned around and immediately shouted: "Array, enemy attack!" ”

But it was too late, Chen Xuan's army from the east wall bypassed there were 10,000 people, but Ping An knew that they must have come out of the city, because he had sent scout cavalry all around, and the appearance of enemy cavalry would inevitably alert him. Since there was no warning from the scouts, then these people must have been hiding in the city for a long time, so when did they enter the city? Now it is easy to figure out that it must be the cavalry hidden in the eastern city when Chen Xuan entered the city, and when his focus was on Song Xuan and Zhang Wu, they quietly entered the city.

And Chen Xuan is ruthless enough, Baoding City is crumbling, he frequently sends death squads, but he has not moved a single cent of this cavalry, just waiting for this fateful moment.

Ping An's brain was fast at this time, and he figured out everything in an instant, but it didn't help. He quickly analyzes the situation on the battlefield and looks for the best strategy. He immediately ordered Wu Jie to defend to the death, and must withstand the two-sided attack of Chen Xuan and Xue Lu, and transfer the 10,000 infantry facing the south gate to support Wu Jie, striving to stabilize the position and prevent Chen Xuan, Xue Lu, and Zhu Di from converging. Liu Sui's chariot formation was ordered to speed up and separate Zhu Neng, and Ping An himself led the remaining 10,000 infantry to speed up the pace and attack Xue Lu and Zhu Di's flanks.

Ping'an's strategy is very simple, Chen Xuan came from the east, and tried his best to block it in the east, and the remaining infantry and chariot formations were also the same strategy, attacking Zhu Di and Zhu Neng from the west, forcing them to turn to the east, so that a situation would be formed between the east and the west, as long as the front could be stabilized, Ping An believed that with the advantage of troops, he could at least remain undefeated.

However, Zhu Di's army shook the flag, the south gate of Baoding City was opened, and Li Jun personally led the remaining defenders of about 4,000 people to pour out and attack the flank of Wu Jie's army. Although the army in Baoding City is not many in number, but the morale is strong, they are already desperate in the morning, but they did not expect that the peak will turn around in the afternoon, to win a big victory, at this moment, they are like a chicken blood, roaring forward.

Seeing this, Ping An had to order the troops in the large camp to come out of the camp to support.

In this way, both sides of the battlefield had no mobile force at all, and they were completely beaten into a pot of porridge, and Ping'an personally led his troops to rush into battle and went straight to Zhu Di's royal banner. The shouts of killing shook the heavens and the earth, and the blood flowed on the battlefield, but today's sunset was particularly slow, as if God thought that today's blood was not enough. In the end, the first to collapse was Wu Jie, who was besieged on three sides, the phalanx was broken, the army was defeated, Chen Xuan and Xue Lu converged, and Wu Jie himself died under Chen Xuan's knife.

Fortunately, Ping'an had already adjusted the formation, combining Liu Sui's car formation, Song Xuan's cavalry and his own infantry to block Zhu Di's attack. After Zhu Di defeated Wu Jie's army, he immediately formed a fan-shaped encirclement, wanting to surround Ping'an and others, and the Ping'an army was not to be outdone, and arrows rained down to prevent Zhu Di's army from approaching.

Just when Zhu Di was full of ambition and was about to press the whole army, the gate of Baoding suddenly opened, and a cavalry rushed out and slashed at Zhu Di's rear army. After fighting for a long time, the already exhausted Yan army was caught off guard, unable to resist at all, and was cut to the ground by a large area. Seeing this, Ping An was overjoyed, and immediately ordered Song Xuan to attack, and the chariot array moved forward, and a large number of feathered arrows were shot towards the Yan army.

The Yan army fought for a long time, and finally turned the disadvantage into a victory, but in the end it was knocked into the dust at the juncture of the immediate victory, and soon it could not be supported, Zhu Di had to order a retreat, Song Xuan and the later cavalry then pursued and killed, Zhu Di himself was almost caught up near Xushui, at a critical moment, Song Xuan and others were repelled by a cavalry from the north, Song Xuan himself was injured by an arrow, and had to stop the pursuit and return to Baoding.

At this point, the battle of Baoding that began with the Battle of the Tang River finally came to an end, and Ping An won the victory, but the losses were heavy, the general Zhong'an Luhou Wu Jie, the commander of the Guards Cavalry Corps, Lin Tianmu and Morgen were killed, Song Xuan was wounded by a cold arrow when pursuing Zhu Di, and his life was in danger, and countless other middle and low-level officers were killed in the battle; The total strength was sharply reduced to 50,000, even if the 10,000 infantry and 5,000 cavalry led by Fang Zhao and Li Yuan, the commander of the Bauhinia Pass who captured Baoding City at the last moment and attacked Zhu Di, were only more than 60,000 people, and the battle losses reached more than 100,000 when Zhending set out, of which there were only more than 5,000 people left in the Guards Cavalry Army, and all of them were wounded.

Before the war, Zhu Di's army, together with the army in Baoding City, totaled 80,000 cavalry and 30,000 infantry, and lost 20,000 on the Tang River, and the cavalry was reduced to 60,000. And because Sheng Yong was besieging Tongzhou, Zhu Di ordered Zhu Gaoxu to lead 10,000 cavalry to return north, and 10,000 of the remaining 50,000 cavalry secretly entered Baoding City, and 40,000 stayed in Xiongxian. Therefore, Zhu Di used 50,000 cavalry and 20,000 infantry against Ping'an's 110,000 infantry and 35,000 cavalry. In the end, Zhu Di lost Baoding City, the infantry was annihilated, the cavalry was less than 30,000 people, and the battle losses amounted to more than 60,000 people.

After this battle, Ping'an's vitality was greatly injured and he was unable to advance north, so he could only have a Beijing division and ask for reinforcements. After this battle, the Yan army no longer had the qualifications to be empty-sighted, and when the battle losses were counted, all the generals of the Yan army were silent, and Zhu Di cried loudly.
