After Baekje was destroyed, on behalf of His Majesty the Emperor of the Tang Dynasty, King Li You of Qi issued a policy of reassuring the people of the original Baekje subjects, stipulating that all the people of Baekje would enjoy the national treatment of the Tang Dynasty, and that the uniform land system would be implemented in Baekje, with tax exemption for one year, tax reduction for three years, and exemption from unpaid labor, which was supported by the people, especially the grassroots people.

For the former Baekje Buyeo nobles, those who had meritorious service in the battle of Baekje annihilation were rewarded and awarded the corresponding titles to the Tang Dynasty. The imperial court also compensated them for the land that was handed over to the state in accordance with the regulations during the land reform. Such a policy did not arouse fierce opposition from them.

In short, the Tang Dynasty's lenient policy stabilized the situation in the former Baekje, allowing it to smoothly incorporate into the Tang Dynasty.

The royal palace of the city of Gübal.

After King Wu's family was sent to Chang'an, the Baekje Palace became the Grand Marshal's Mansion and the Baekje Governor's Mansion on the Eastern Expeditionary Army's East Road (as opposed to the Eastern Expeditionary Army's West Road under the command of Li Shimin).

On this day, the military and political officials of the Baekje Governor's Office gathered to listen to the commendations and personnel appointments issued by the imperial court issued by the King of Qi, Yi You.

In view of the excellent performance of Liu Renliang, Sima Jiong, Cheng Chuliang and others, the imperial court canonized Liu Renliang as the Duke of Lantian County, Sima Jiong as the Marquis of Baekje, Cheng Chuliang as the Marquis of Jubacheng, Wang Jue as the Marquis of Gwangju, Wang Yaozu and Qiao Bin of the Marine Corps, and Liu Anjin and Shen Ming of the former Dengzhou Army all obtained the title of nobility.

The main officials of the Baekje Governor's Office were:

Governor Sima Jiong, Deputy Governor Yan Changhan, Changshi Yuan Dengzhou Assassin Yao Dong, Sima Cheng Chuliang, etc.

Subsequently, Li You, the king of Qi, issued an order for the reorganization of the Eastern Route Army of the Eastern Expeditionary Army:

The marshal Li You, the deputy marshal Hou Junji and Zhang Liang had jurisdiction over 220,000 Tang Army and 50,000 Navy.

When the order was announced, everyone rejoiced.

Next, the Eastern Expeditionary Army's East Route Command held its first operational meeting after the reorganization. The content of the meeting was the direction of the Eastern Route Army's march.

For the attack on Baekje, Hou Junji did not catch up, and he was a little angry in his heart, he studied Goguryeo in advance, and already had a mature battle plan for attacking Goguryeo.

He said: "Your Highness, the minister thought that the sea area along the coast of Goguryeo would be blocked by the navy, and then the army would be divided into two routes, one from the Kaesong area to the west, and the other from the Taedong River estuary, and the two armies would go straight to Pyongyang. ”

Zhang Liang and others also studied the battle plan for attacking Goguryeo, and everyone thought that Hou Junji's opinion was both sound and effective, and they all agreed.

Recognized by the generals, Hou Junji was very happy, and he asked, "Your Highness, what is your opinion?" ”

Li You said: "Chen Guogong is worthy of being the top military talent in my Tang Dynasty, and the battle plan he formulated is very good.

However, Goguryeo, unlike Baekje, and even all other countries, was an extremely difficult opponent to deal with.

For hundreds of years, Goguryeo defeated the Central Plains Dynasty countless times, and even the Tang army suffered a setback last year. In this case, the Goguryeo people had strong self-confidence in their hearts, and they would put up very stubborn resistance to the attack of the Tang army.

Using general tactics, even if Goguryeo could be destroyed, the Tang army would have suffered significant losses. Moreover, in this case, if Goguryeo is defeated, the Goguryeo people will also suffer heavy casualties, and the dependents of these people will accumulate great hatred for the imperial court.

Such a Goguryeo will be a mess if it is defeated, and it will be very difficult to govern in the future, and it will involve a lot of energy from the imperial court. ”

Hou Junji and the others all considered it militarily, and when they heard Li You say this, they all thought it made sense.

Over the years of the Tang Dynasty, new territories such as the steppe, the Western Regions, Jeju Island, Persia and Bajistan, including the current Baekje, were all completed under the command of His Royal Highness the King of Qi, and everyone recognized his authority.

Zhang Liang said: "Your Highness, if you say how to fight, the ministers will listen to you." ”

Although Hou Junji's opinion was rejected by Li You, he thought that Li You must have a better idea. He said, "Yes, Your Highness, what do you say, the ministers will obey your orders." ”

Everyone said that they listened to Li You's opinion.

Li You said: "To deal with Goguryeo, we must first demoralize them and cause their people to lose trust in their court, so that after internal contradictions, it will be twice the result with half the effort to attack." ”

Everyone agrees with what Li You said, but everyone has some questions about how to do it.

In order to enhance the generals' overall view of the problem, Li You said: "You can discuss what I said, how can we do it? ”

This problem is so difficult that even Sima Jiong, a talent with both military and political skills, can't think about it for a while.

In the end, the crowd couldn't figure out how to do that.

Hou Junji asked: "Your Highness, the minister is a little dull, the minister thinks that the Goguryeo people will definitely be more united in the face of the pressure of the Tang army. How can the kind of outcome you are talking about happen? ”

Hou Junji didn't doubt Li You, but he really couldn't think of it himself.

Everyone focused their eyes on Li You.

Li You said with a smile: "Today I will tell you a new method of warfare, which is called three points of military, seven points of politics, and an integrated battle of military and political economy. ”

Li You pointed to the map of Goguryeo and said, "Everyone, please see, Goguryeo is a long and narrow area, and the strategic space is extremely limited. This provides very favorable conditions for the kind of tactics I have mentioned.

First of all, the powerful navy of the Tang Army blockaded the waters of Goguryeo from the sea, cutting off the entry and exit of all Goguryeo ships, and even fishing boats were not allowed to appear on the seaside. In this case, all of Goguryeo's foreign aid by sea was cut off.

Goguryeo itself has a small land area, and its interior is mostly mountainous, and its products are limited. The Tang army was strong and strong, and it was not difficult to blockade it on land.

In this case, their poor resources will not be stretched out of the box in a short time.

In particular, salt was not produced in Goguryeo, and after the blockade of the sea, the supply of salt was cut off. In this case, their internal storage of salt is quickly depleted. People don't have the strength to eat salt, and when they can't even pick up swords and guns, won't this battle be much easier to fight? ”

"yes, that's a good idea." The crowd talked lightly.

Li You continued: "In order to speed up this process, the navy and the army will carry out landing and sneak attacks from all over the place, burning their crops and houses, and destroying their production and living resources as much as possible.

Our armies on the eastern and western routes adopted fortress tactics, advancing only three to five miles a day on average, and then adopted a defensive posture, repairing forts, digging trenches, and forcing the Goguryeo people to fight with our army. Our army has powerful bows and crossbows, and the soldiers have armor with strong protection, and in the state of defensive warfare, the Goguryeo people will pay a greater price.

When encountering a city, we have fierce fire oil and a large number of craftsmen, who can make siege engines, and can defeat most of the cities. When they encounter a strong city, they adopt the method of besieging it.

Let's just advance slowly, constantly compressing the living space of the Goguryeo people, and it won't take long, at most, a year, for the Tang Army to set foot on the entire Goguryeo.

Actually, it won't take that long at all.

As the territory of Goguryeo continued to shrink, their military and civilians would continue to retreat towards the center, and the population density would increase, but the resources would become less and less. In such a situation, there will inevitably be huge contradictions within them in order to allocate resources.

The Goguryeo aristocracy, in order to ensure their own supply and the supply of the army they kept in captivity, would definitely squeeze the common people.

Once this happens, their morale drops dramatically. When the time comes, as long as we put a few cauldrons outside and let the aroma of the food waft into the camp of the Goguryeo people, their people will run out and ask to be taken in, and their officers and soldiers will throw away their swords and guns and come out and surrender.

At this point, do you still need to fight this battle? ”
