The Tang army continued to pour into Changkou City, and soon gained the upper hand, in this battle, the Tang army was prepared to fight unprepared, with more people to fight less, with the help of time and people, to take Changkou City.

Seeing that the situation was like this, the defenders of Changkou could not fight, so they simply laid down their arms and surrendered.

If you resist any longer, it is undoubtedly a dead end, and if you surrender to the past, you can still leave a life.

Changkou's battle is easy to say, and it is more difficult to say that it is not easy, because the preparation time is too long, for this first battle, just after the New Year, Su Dingfang first went to Hebei, and then led the troops to Dengzhou, Shandong, and waited in Dengzhou for more than half a month before waiting for this opportunity.

There were only 8,000 guards in Changkou City, and after the battle, there were 5,000 soldiers left, all of whom were locked up in the military camp of Changkou City, and the army under Su Dingfang successfully took over Changkou City.

After capturing Changkou Fortress, Su Dingyi found people who were proficient in the Goguryeo language, and began to post notices of peace everywhere in the city.

It is easy to conquer a city, but it is difficult to conquer a city, and after a big war, how to govern it is the most important thing.

The government office of Changkou City, Su Dingfang naturally settled in it, and this government office also became the command place of Su Dingfang's army.

"General, everything in the city has been arranged, what should we do next?" The adjutant general beside Su Dingfang asked.

"To the north of Changkou is Pyongyang City, Quangai Suwen is in Pyongyang City, Pyongyang City has more than 50,000 Goguryeo elite soldiers, and it is personally led by Quangai Suwen, with our current strength, it is not cost-effective to fight Pyongyang, so next, the goal of the army may as well be placed to the south, and first fight a few battles to enrich the strength of our army." Su Dingfang said.

"The general already has a goal?"

Su Dingfang nodded: "Well, here." ”

Su Dingfang stood on the hanging map money, and the direction of his finger pointed to Kaesong, southeast of Changkou.

"Kaesong is the southernmost city of Goguryeo, very close to the territory of Silla, the Tiangao Emperor is far away, and the Pyongyang city side is almost not very governed here, so the best way to raise the war by war is to fight all the way to Kaesong, then Kaesong, the south of Kaesong and Changkou are connected, and the place in the middle is all under our control, and behind is Silla, you can rest assured for the time being." Su Dingfang said: "In this way, the entire Goguryeo, the two most important cities are only left with the three important cities of Daxingcheng, Bozhuo City and Pyongyang City. ”

As for Bo Zhuo City, Xuan Shijing and Su Dingfang did not take it into account, Bo Zhuo City is close to Yi Mountain, it is an easy place to defend and difficult to attack, and it is not close to Pyongyang City and Daxing City, as long as Da Xing City is taken, when the two armies besiege Pyongyang, there are two roads on the side of Bo Zhuo City, one is to send troops to rescue, in this way, it can be regarded as leading the snake out of the hole.

Or they continue to choose to shrink back, watching the city of Pyongyang being breached by the Tang Dynasty, and finally being besieged by the Tang Dynasty.

Therefore, Bozhuo City is not very important to the Liaodong Army and Su Dingfang's troops, and it is not a place that must be taken.

The defenders of Bozhuo City, guarding Bozhuo City, may have the strength to fight with the Tang army, but once they leave the city, they are nothing in front of the Tang army.

The combat effectiveness of the sergeants of the Tang army is not ordinary, and the weapons and armor of the soldiers are not comparable to the Goguryeo army at all.

When the Tang Dynasty army attacked the Turks, what did they rely on, the soldiers were well fed, the surveillance of the armor, and the sharpness of the weapons.

After all, the men on the steppe are warriors when they get on horseback and pick up swords and bows, and they are natural warriors.

Changkou City was taken, and Su Dingfang didn't plan to move for a short time, because he learned from the surrendered Goguryeo soldiers that the Goguryeo naval army would return to Changkou for supplies in the near future, and if Su Dingfang took people away, the captured Changkou City would be too easy to be recaptured by Goguryeo's sailors.

Su Dingfang was different, 50,000 Tang troops refused to defend the city, and the sailors of Goguryeo got off the ship to attack the city, and Su Dingfang could definitely fight them, and they couldn't find the north.

There is still some difference between a sailor and a soldier on land.

The news that Changkou City was taken by Su Dingfang did not reach Pyongyang City until seven days later, and Quangai Suwen saw the news sent by the messenger on the sickbed, and only a mouthful of blood sprayed on the side of the bed.

"Your Excellency!" Seeing this, the people around Quangai Suwen hurriedly stepped forward to help Quangai Suwen up, and at the same time shouted outside the palace: "Quick! Get the healer here! ”

Quan Gai Suwen lowered his head and waved his hand with difficulty: "It's okay, I know my own body." ”

Quangai Suwen was furious, and Daxingcheng didn't let him worry, but Changkou's side was taken by the Tang army without warning, what were those spies for? So many people have arrived near Goguryeo and have not heard their traces, or did they only find out after the city was taken, and there are sailors, and there are no clues found on the sea?

Quan Gai Suwen breathed a sigh of relief and leaned on the pillow behind him: "Do you know who took the long mouth?" ”

"Lord Hui, now on the head of Changkou City, there is a big flag with the word 'Su' written on it, and the lower officials dare to guess, I am afraid that it is Su Lie and Su Dingfang's army."

"Su Dingfang ......." Quan Gai Suwen smiled bitterly: "This person is brave and good at fighting, and his courage is amazing, when the Tang Dynasty attacked the Turks, he attacked Yinshan at night, Su Dingfang led two hundred cavalry to the battle first, and broke through the tooth tent of Jieli Khan, two hundred people..... Hehe. ”

The official next to the "Adult ......." saw Quan Gai Suwen's expression, and the feeling in his heart was also uncomfortable, now that the situation has become like this, if he wants to save it, I am afraid it will be difficult, unless Da Mo Lizhi recovers immediately and personally leads the army to meet the Tang army, but, is this possible?

"Quickly let people contact the navy, don't go back to Changkou, go directly to the vicinity of Pyongyang to make supplies, now Changkou is a trap for the navy, the navy will definitely fall into it in the past." Quan Gai Suwen said.

"Yes......."

"In addition, send 20,000 troops to the vicinity of Changkou, clear the wilderness, and take everything that can be taken away, and don't leave any heavy goods for the Tang army." Quangai Suwen instructed: "The Tang army is alone in the depths, and there is no supply, I want to see how long Su Dingfang can hold out." ”
