After Li Shimin recovered Luzhou, in early April, he caught up with Song Jingang in the Bird Mouse Valley.

Fierce battles were fought on both sides.

Within one day, Li Shimin and Song Jingang clashed eight times, all of which were victorious.

In the end, Song Jingang escaped by luck and led the rest of his army to retreat north.

Arriving outside Yong'an City, Song Jingang carried out a new round of deployment: "Looking for the appearance, you lead the troops to guard Yong'an." ”

"Wei Chi Jingde, you guard Jiexiu, and the others will follow me to help Your Majesty."

At that time, Liu Wuzhou was still attacking Haozhou, and Song Jingang thought that Li Shimin's army was too fierce for him to beat, so he simply went to help Liu Wuzhou defeat Haozhou, which could be regarded as a city.

Wei Chi Jingde and Xun Xiang received the order, and seized the time to deploy defenses to resist the Tang army.

Li Shimin sensed Song Jingang's intentions and immediately ordered: "Liu Wenjing, you and Li Shiyun lead troops to intercept Song Jingang, and you must not let him join Liu Wuzhou." ”

"Yes, Marshal."

Liu Wenjing and Li Shiyun immediately led the elite cavalry to intercept from the southwest.

Li Shimin led his troops to Yong'an City, and sent Yu Wenshi and Li Daozong to Yong'an and Jiexiu to recruit An and Wei Chi Jingde.

After looking for the Yu Wenshi, he touched the wound on his thigh that had not yet healed, and looked up to the sky and sighed: "The Tang army is vigorous, and we can't resist." ”

So, Yong'an City surrendered to Li Shimin.

And after Wei Chi Jingde heard that Xunxiang surrendered, the fighting spirit in his heart was instantly extinguished.

He glanced at the wound on his shoulder, and thought of the scene when the Tang army attacked Huzhou, and his expression was particularly tired.

"Providence is like this, how can I disobey it?"

As a result, Wei Chi Jingde surrendered to Li Shimin in Jiexiu City.

Li Shimin was very happy to harvest two cities and two fierce generals at once, and immediately appointed Lieutenant Chi Jingde as the commander of the right first government, and Xun Xiang as the deputy commander of the right first government, and followed him to continue north.

......

On this day, Song Jingang stopped the army to rest, and as soon as he sat down, there was a sound of horses' hooves around, and then the soldiers of the Tang Army appeared in front of them.

"Kill!"

Liu Wenjing didn't say a word, and led the cavalry to charge directly.

Li Shiyun, Zhang Liang and others rushed into the enemy camp from different directions, rushing back and forth, as if the killing god had descended into the world, and the corpses were quickly piled up into small mountains.

Song Jingang has been in a state of escape during this time, physically and mentally exhausted, and has long lost the vigor when he invaded the state.

After the fierce confrontation, seeing that there were fewer and fewer people in his own country, Song Jingang hurriedly ordered: "Retreat, retreat." ”

Because the Tang army was blocked in front, Song Jingang retreated when he was back and forth.

fled all the way to the vicinity of the West Gate of Jiexiu, and when he saw the Tang Army flag planted on the city wall, he hurriedly shouted to stop.

"Stop moving."

The general saw the military flag on the city wall, and his face was full of anger: "Didn't Wei Chi Jingde claim that he was invincible? It's only been a few days, and I threw Jiexiu away, it's really useless. ”

At this time, the scout in front came to report: "King Song, Wei Chi Jingde and Xunxiang have taken refuge in the Tang Army." ”

"Bastard thing!" Song Jingang couldn't help but scold: "A manly man, how can you surrender to the enemy?" ”

"Everyone obeys the order, fights to the death with me, and vows not to surrender."

Suddenly, the soldier's fighting spirit was ignited by Song Jingang again, shouting: "Fight to the end, vow not to surrender." ”

So, Song Jingang set up an array outside the west gate, which was several miles long from north to south, and the scene was very strong.

When Li Shimin heard the news, he rushed to the city wall and picked up a telescope to observe.

After observing, he said to everyone: "Song Jingang only has 20,000 horses now, and his morale is low, so there is nothing to fear. ”

He immediately ordered: "Qin Shubao, you and Duan Zhixuan will lead the troops out of the city, and fight Song Jingang with Liu Wenjing and them." ”

"Knock-knock-"

The drums are beating loudly, and the smoke is rising again.

Song Jingang fought against the water, and the fighting spirit of the soldiers was all stimulated, and the battle with the Tang army changed from the cowardice of the past and became very fierce.

Li Shiyun and Liu Wenjing were defeated and retreated a few miles, and Qin Shubao and Duan Zhixuan also fell behind.

Seeing this, Song Jingang was overjoyed and took the opportunity to fight back to the east, wanting to capture Jiexiu City.

At this time, Li Shimin personally led 3,000 cavalry to attack from the south, and Song Jingang was caught off guard.

"Retreat, retreat."

Although Song Jingang gave the order to retreat, his army was besieged on three sides and it was difficult to get out.

This battle lasted for two days and two nights, and Song Jingang's army was killed and wounded, and led the rest to flee north.

Li Shimin chased more than ten miles and killed hundreds of people before returning to the camp.

......

"What? Song Jingang was defeated? ”

Liu Wuzhou was shocked when he heard the news of Song Jingang's defeat.

He always believed that Song Jingang could help him capture Bingzhou, and then Guanzhong, and even the entire Central Plains.

Unexpectedly, in just a few months, the city defeated by Song Jingang returned to the hands of the Tang Army.

After careful consideration, he gave the order: "The whole army retreats and returns to Jinyang." ”

Seeing that Liu Wuzhou's army had withdrawn from the city of Haozhou, Li Zhongwen breathed a sigh of relief and finally kept Haozhou.

Subsequently, Li Zhongwen sent someone to report to Li Shimin.

Li Shimin was heading to Jinyang, and after learning the news, he ordered Li Zhongwen to garrison Haozhou, and sent Cheng Zhijie and others to set off from Haozhou and enter Jinyang City.

At the same time, the army led by Liu Hongji set out from the southwest direction and also advanced to Jinyang City.

All of a sudden, the armies galloped towards Jinyang.

As soon as Liu Wuzhou returned to Jinyang, he received the news that Li Shimin led various armies to prepare to besiege Jinyang City, and was so frightened that he didn't even enter the city gate, so he fled in the direction of the Turks.

As soon as the army left, Song Jingang rushed to Jinyang, wanting to collect the rest of Jinyang City and prepare to fight again.

It's a pity that everyone was unwilling to fight with the Tang army anymore, and they all said that they wanted to surrender to Li Shimin.

Song Jingang was furious and wanted to kill them, but was stopped by the commander of his own soldiers.

The commander of the personal army said: "King Song, Your Majesty has fled, we are gone, if we force them to fight the Tang army now, I am afraid that it will provoke a mutiny, and your life will be in danger at that time."

"Why don't we follow Your Majesty to the Turks as well."

Liu Wuzhou even gave up the originally occupied Mayi, which shows how powerful the Tang army was.

Even if the remaining soldiers worked together, they couldn't defeat the Tang army, not to mention that the Tang army had such powerful weapons, and the speed of the siege was staggering.

Song Jingang thought for a while and decided to abandon Jinyang City and lead hundreds of guards to flee to the Turks.

At this point, Li Shimin recovered all the lost territory in the state, and all the captives returned to the Tang Dynasty.

However, Li Shimin did not withdraw his troops, but took the opportunity to attack Liu Wuzhou's territory to the west, and at the same time ordered Guo Zihe, the governor of Lingzhou, to lead the army from Yulin to attack Shuofang and other places.

Hearing that Liu Wuzhou was defeated, the surrounding states and counties surrendered.

At this time, the Eastern Turkic Khan was the Luo Khan, the brother of the Shibi Khan, and he was very unhappy when he saw Liu Wuzhou's army defeated and returned.

Originally, the Eastern Turks supported Liu Wuzhou because they wanted to control the situation in the Central Plains, but they knew that Liu Wuzhou was no match for Li Yuan and was defeated.

However, the Khan of Chuluo welcomed it.

After staying for a while, Liu Wuzhou noticed Luo Khan's estranged attitude everywhere, and didn't want to stay any longer, so he conspired with Song Jingang to return to the Central Plains, preparing to make another big move.

Unbeknownst to him, the Khan sent troops to capture Liu Wuzhou and Song Jingang and kill them.

Soon after, Luo Yi, the governor of Youzhou, returned to the Tang Dynasty.

Li Yuan was overjoyed, and immediately named Luo Yi the king of Yan and gave him the surname Li.

At this point, the northern part of the Central Plains was unified under the Tang Dynasty......
