The situation on the battlefield is changing rapidly, and no one knows what kind of changes will occur in the next moment, for example, when Quangai Suwen went to Bogoukou, he did not expect that a cavalry of the Tang Army would come across the sea and suddenly kill under the city of Pyongyang, and Li Shimin would not have thought that when the way was blocked by the Yalu River, a fleet of Silla people would suddenly appear.

With these Silla fleets, Li Shimin finally restarted the plan to attack Bogoukou, and after several days of preparation, a new round of offensive finally began today, with 2,000 carefully selected soldiers taking the lead in boarding the ships, and then all the ships set off together and rushed to the opposite shore like arrows.

Li Shimin also went out of the camp early to watch the battle, originally he thought that Bogou Kou would definitely send troops to intercept and prevent the ships from docking, and this was also the most favorable time to strike at the landing of the Tang Army, but what he and everyone did not expect was that there was no movement at the mouth of Bogoukou, and the city gate was tightly closed, as if the Tang Army was allowed to land?

"Strange, how can the Goguryeo people not move at all?" Even Li Xiu, a layman, couldn't help but show a surprised expression when he saw the closed gate at the mouth of the ditch, when the pontoon bridge was built before, the other party didn't give Tang Jun the slightest chance, but now that the boat is about to dock, the other party has no reaction, which is really strange.

Li Shimin also frowned at this time, Cheng Yanjin, Li Ji and others also discussed a few words in a low voice, but in the end they did not discuss any results, at this time, I saw that the ships of the Silla people also began to dock, and then the Tang army soldiers also landed on the land on the other side, but there was still no movement at the gate of the other party.

"Ignore them, send another batch of people!" Although Li Shimin felt that the reaction of the Goguryeo people was strange, but at this time, the arrow was on the line, and the people had already been sent over, and it was impossible to withdraw again, and since there was no response from the other side, then send some more people over, and the craftsmen here also began to work together to build a pontoon bridge, after all, tens of thousands of horses, plus baggage and other items, could not be transported by ships alone.

The second batch of soldiers was also quickly transported over, and even the pontoon bridge was halfway built, but there was still no movement at the mouth of the Bogou on the opposite side, Li Shimin and others looked at the other party's city with binoculars, and they could also see many defenders, but the other party not only did not go out of the city, but did not even put an arrow.

Seeing this situation, Li Shimin and others also felt that something was wrong, and then he discussed it with Cheng Yanjin, Li Ji and others, and then decided to let the Tang army who crossed the river test the reaction of Bogoukou, so the other side quickly organized a siege team and rushed to the gate of Bogoukou with a shield.

Then what everyone didn't expect was that just as the Tang army rushed to the vicinity of the city gate, they saw that the city gate was suddenly opened, and then they saw a group of Goguryeo people walking out of the city gate with a white flag, and it seemed that they were going to surrender.

Some time ago, the Tang army was blocked at the mouth of Bogou on the west side of the Yalu River, and today it suddenly surrendered, which made everyone unable to come to their senses, and even Li Xiu thought that he was dreaming, after all, the other party's surrender came too suddenly.

However, after reacting, some people soon thought that Bogoukou might be a fraudulent surrender, and even Li Shimin had such concerns, so he immediately ordered the Tang army on the other side to be careful, but soon the Tang army rushed into the city gate, and appeared on the city head after a while, and the entire city gate was completely controlled by the Tang army, and it was impossible to surrender by fraud at this time, after all, the city gate was handed over to the Tang army, and no matter how many troops in the city were, it was useless.

Seeing the banner of the Tang Dynasty erected on the head of the city, Li Shimin and others had to believe it if they didn't believe it, but at this time, everyone had a big question mark in their hearts, and they couldn't figure out what was going on? However, those Goguryeo people who surrendered could definitely answer the questions in their hearts, so Li Shimin immediately ordered someone to bring the surrendered people over.

After a while, I saw a gray-haired old man being brought to Li Shimin, and then the other party gave Li Shimin a deep salute and said: "Xu Hong, the guard general of Bogoukou, meet His Majesty the Emperor of the Tang Dynasty!" ”

"What about Quangai Suwen, why didn't he come to see me?" Li Shimin glanced at the other party lightly at this time and said.

"Your Majesty, Da Mo Lizhi received the news that Pyongyang City was besieged by the Tang army a few days ago, so he led his troops to leave Bogoukou two days ago, and now there are only 1,000 defenders left in the city, and the subordinates know that they can't resist the heavenly army, so they took the initiative to open the city gate and surrender!" I saw this Xu Hong replied again.

"You left two days ago, so why didn't you open the city gates and surrender two days ago?" When Li Shimin heard Xu Hong's words, he couldn't help but be annoyed and angry.

Quangai Suwen has been gone for two days, and it is estimated that he may be almost in Pyongyang City now, and what is even more hateful is that he has not even noticed it in the past two days, it is estimated that this Xu Hong has deployed all his troops on the city, and he is looking at each other across the river, even if it is a telescope, he is confused by the other party.

"Xu Mou originally had no talent, but Meng Da Mo left the branch, so I was appointed as the guard of Bogoukou, when Da Mo left the branch, told me to drag on for two days no matter what, at that time Xu also agreed, the Central Plains saying is called a gentleman's word, a horse is difficult to chase, although Xu does not dare to call himself a gentleman, but he also does not want to be the person who breaks his word!" I saw this Xu Hong's expression was very calm.

"What a gentleman! But do you know that because of your delay, it may cause Quangae Suwen to flee back to Pyongyang City, and there are still 10,000 troops on the side of Pyongyang City, and if you encounter danger because of this, you will be responsible for your death! Li Shimin's anger did not diminish because of Xu Hong's words, but asked more annoyedly.

Quangai Suwen's escape may not only lead to danger for Su Dingfang's army, but also when Quangai Suwen returns to Pyongyang City, Datang will have to pay a lot of price to take Pyongyang City, although these can't all be blamed on this Xu Hong, but they also have a great relationship with him.

In the face of Li Shimin's anger, the guard general Xu Hong was also silent at the moment, and after a while, I saw him say slowly: "Since Xu Mou dared to stay, he had already put life and death out of the way, but I just hope that Your Majesty can let go of the thousand defenders in the city, they are either old and weak, or sick and disabled, and they have no threat to the Tang army at all, and they can't keep up with the actions of the army, so they were left behind by Da Mo." ”

"Hmph, now is not the time for you to put forward conditions, take him down to me!" When Li Shimin heard that Xu Hong dared to put forward conditions, he also snorted coldly at the moment, and then someone immediately took this Xu Hong down.

Bogoukou fell into the hands of the Tang army almost effortlessly, but Li Shimin was not happy anyway, mainly worried about the safety of Su Dingfang's side, in case Quangai Suwen and Pyongyang City were flanked in front and back, Su Dingfang's 10,000 cavalry may not be able to resist?
