Datang: Li Shimin begged me to rebel

Li Shiji took Liaodong City for 20 days. With the latest messengers entering Liaodong City, Jian'an City, the last city on the entire Liaohe line, surrendered after the city gate was blown down, which means that the entire Liaohe line was completely in the hands of the Tang Dynasty.

And as these cities continued to be taken down, the people around these cities were quickly arranged to return to the villages to cultivate the fields.The national reserve granary from Youzhou is continuously transporting grain and other materials to the entire Liaodong region through the Yellow River → Bohai Sea → Liaohe River.

For Tangshan City, which was built in Youzhou and faced the front line of Korea, the materials delivered here were nothing at all.Because the entire Tangshan city is now regarded as the industrial center of the entire Youzhou and even the north, the steel plant and related processing industries built here will supply the entire northern region for quite some time in the future.

However, according to the information given by His Highness, there are also a large amount of coal, iron ore and other resources near Gaimu City (Fushun). Now Li Shiji doesn't care about farmland and the like. In Li Shiji's view, these mineral resources are the key.

It's just that no one found it.

It took a total of more than 20 cities of different sizes in the first line of Liaodong, and it took a total of more than 20 days. Although this is different from most cities, especially some small cities such as counties, it was after the arrival of the Datang army, Sun Daiyin and the others. After that, he surrendered directly, without any resistance.

But this speed is also fast enough.

In addition to sending the latest news to His Majesty Chang'an and King Qin, Li Shiji had to admit that His Highness the Crown Prince's opinion had a decisive influence.

The [-] cavalry scattered between the Yalu River and the front line of Liaodong almost cut off all the information transmission of Goguryeo, so that they may not know the real situation of the Liaodong front so far.

According to the information received by Li Shiji, during the 20 days, Goguryeo sent [-] cavalry to try to wipe out, or to attack tentatively.

But after the [-] heavy cavalry quickly dispersed into dozens of small groups, and did not get entangled with the opponent, the opponent retreated after chasing a certain distance.

When the opponent retreated, the cavalry unit, which had been fishing from a distance, quickly caught up with the opponent again, and continued to harass the opponent with bows and arrows.

Datang's strong bows and sharp arrows played a decisive role in such harassment. Goguryeo's armor was originally made of iron, and although their horses also had increased armor, the armor of the horses was thinner.

As a result, the arrows shot by Datang caused certain casualties to Goguryeo's heavy cavalry.

And when the opponent turned around and pursued again, Datang's cavalry troops ran while shooting.

Anyway, for Datang, these arrows can be worn out, even if they are all iron arrows.

Although Datang's horses had a heavy burden, Goguryeo also sent heavy cavalry, and Goguryeo's heavy cavalry was even heavier than Datang's.

I can't run fast, and you can't run fast, then we are all the same, there is no difference.

As for the light cavalry that came out with the opponent's heavy cavalry, the opponent's commander obviously used these light cavalry as scouts for scouting and information transmission. In this tug-of-war, the opponent did not dare to send them out.

Even the heavy cavalry can't hold the opponent's armor-piercing arrows, so you let the light cavalry in leather armor go?

What's more, they didn't forget that Datang had nearly [-] heavy cavalry active here!And there are only [-] of them in total, although only a few thousand appeared in front of them, who knows if the rest are outflanked.

So after seeing back and forth twice, Goguryeo's cavalry general retreated decisively, even if the Tang cavalry chased and harassed them, they retreated regardless.

In fact, they did expect something. Qibi Heli and the others were going to try to see if they could gather [-] cavalry to eat the [-] cavalry.

But it's easy to disperse, and it takes time to gather, and the other party didn't give too much time, but let the other party slip away.

But it doesn't matter if they slip away, because even if they slip away, they will leave nearly 700 casualties between them.

Among them, more than 400 died, and the remaining more than 300 injured were sent to Liaodong City by Qibi Heli.

They ran so fast that they didn't even collect many of the iron arrows shot by Datang.

After this battle, the various scouts that the opponent tried to send out were all stopped by the cavalry here.

Especially when Qibi Heli was fighting this Goguryeo cavalry, Li Shiji's side had already completely captured Liaodong City and launched governance operations. After a large number of troops were vacant, most of Datang's troops had already Crossed the front line of Liaodong through Liaodong City, and arrived at the rear of the cavalry like Qibi Heli.

With the support here, Li Shiji directly added [-] light cavalry to Qibi Heli. They only wore key protective armor, and their horses were not armored. They were specially used to chase and block the opponent's scouts.

Then Li Shiji took out another [-] cavalry to join in, and Zhang Liang led the [-] cavalry plus [-] infantry to Beisha City (later Dalian). under Tang's control.

By that time, more than half of Goguryeo's territory had been lost.

……

In Pyongyang, Yuan Gai Suwen was a little anxious. He never expected that Datang would be so difficult, especially the [-] cavalry. He simply didn't know how they persisted for so long.

Although it is said that horses are not needed for logistics supplies, they can be found from the mountains and forests, but what about people?Where did they get so much food?

Those villages?The food needed by [-] cavalry is not a small number. How much food can those villages have?You must know that he has already ordered the cities to gather the nearby people as much as possible before.

It has been 20 days, and all the scouts he sent out have not brought back any news, or in other words, it is not that there is no news at all.

Those who have no news, either went but couldn't come back, or were directly captured by Datang's cavalry.

Even the few ships he sent out trying to go to Beisha City from the sea did not receive any news.

Of course, what Yuan Gai Suwen didn't know was that Datang's fleet was cruising in the Bohai Bay, especially in the waters off Pyongyang. There were quite a few Datang ships, large and small, cruising in this bay.

Qibi Heli and his cavalry had only dry rations at the beginning, but Yuan Gai Suwen didn't expect that Li Shiji and his men would solve the front line of Liaodong City so quickly and be able to quickly replenish Qibi Heli and his team with food and grass. Datang's ships can use small boats to provide logistical supplies to these cavalry from the sea.
