Wang Shichong pursued the Tang army, and he was about to catch up, but found that the Tang Dynasty army had already arrived one after another. He ordered the pursuit to be halted and retreated to the Cijian camp.

As night fell, the follow-up armies of the Tang Dynasty rushed to the Cijian front, the soldiers lit torches, and the sporadic procession stretched for miles.

After the scout reported to Wang Shichong, he deeply felt that the Tang army was strong, and thought that Cijian was open and there was no danger to defend, so he could not fight with the Tang army here, so he ordered all 30,000 troops and horses to withdraw to Luoyang City.

The Tang Dynasty army withdrew when they saw Wang Shicheng at night, and the original plan to attack the camp was cancelled.

The next day, Li Shimin ordered the whole army to march into Cijian City, and he prepared to stay here for a few days as a temporary command post for the army.

That night, the sky was clear, and as the first quarter moon gradually rose high in the sky, most of the soldiers fell asleep.

Li Shimin began to discuss the overall strategy of the siege of Luoyang with the strategists in the big tent. One of the reasons why I chose to discuss the meeting at night was because of confidentiality; The two are quiet at night, and it is easy to concentrate on ideas.

In the tent of the Chinese army, there is a cowhide map, which shows in detail the distribution of mountains, rivers, plains, passes, and cities around Luoyang. With Luoyang as the center, the situation of mountains and rivers is at a glance in this map.

The strategist Du Ruhui spoke first, he pointed to the map and said to Li Shimin: "Your Highness, please see, Luoyang City is surrounded by mountains on three sides, the east is open, Yishui and Luoshui cross in the middle, and there is a canal leading to the Yellow River in the east. Our army can transport huge boulders to cut off the ship route, and then send heavy troops to guard the land pass on the west, north and south sides to cut off the enemy's grain route. If you persist in this way, Luoyang City will definitely be in trouble. ”

Li Shimin nodded and said, "When the time comes, we will come to him to catch turtles in an urn!" ”

Hahaha...... All the soldiers laughed out loud in unison.

At the end, the elder strategist Fang Xuanling spoke: "Your Highness, our army is pressing the border, and a large number of Zheng Guozhou County will come to surrender at that time. In order to prevent Wang Shichong's army from being defeated and fleeing south into the territory of Xiao Mill, His Majesty had already ordered Li Daliang to take 3,000 cavalry to Xiangyang to respond. In addition, His Royal Highness can also mobilize our army's soldiers and horses stationed in Taihang Mountain, Funiu Mountain, Bear's Ears Mountain and other mountains to intercept and rescue the enemy army in Luoyang halfway, and completely cut off the foreign aid of Luoyang City! ”

Li Shimin said happily: "Han Xin's 'ambush on all sides', even if he is as brave as the overlord Xiang Yu, he can only kill himself." I think Wang Shichong will not escape this catastrophe even if he puts on his wings! ”

……

The summer night is exceptionally clear, and a crescent moon leaps into the sky, appearing and disappearing in the clouds. The sky is full of stars and is exceptionally bright.

Li Shimin came out of the account to relieve himself, he saw that it was getting late, so he said to his generals and strategists: "It's not early, everyone go back to rest, and issue the marshal's order early tomorrow morning!" ”

In the early morning of the next day, Li Shimin ascended to the tent, and after all the generals arrived, he personally issued the marshal's order - Shi Wanbao, the head of the march, occupied the dragon gate of Yique from Yiyang; General Lau De Wei captured Hanoi from Taihang; The king of Shanggu cut off the grain road of the eastern capital from Luokou; Huang Junhan, the governor of Huaizhou, captured Los Angeles from Heyin; All walks of life set off immediately, and within three days, they will be in their places, and Pegasus will report!

Li Shimin himself personally led the main force to set up camp at the foot of the mountain in the north of Luoyang City, and the company camp besieged Luoyang City.

Three days later, all the soldiers and horses were in place, and the connection between Luoyang City and the outside world was completely cut off. The Tang Dynasty army besieged Luoyang City, preparing to launch a comprehensive general attack on Luoyang City when the food in the city was exhausted and the soldiers were tired.
