The beginning of the Three Kingdoms Cheng Yuanzhi

Chapter 212 The main theme of war is always profit

On the other side, the time was turned back to autumn, and Cheng Yuanzhi besieged Gongsun Kang in Yingkou.

There is a reason why he is obsessed with Liaodong.

Since the unification of the Central Plains by the Qin Dynasty, the Central Plains Dynasty has never completely conquered the Korean Peninsula for more than 2000 years.

He wants to set this precedent.

Of course, the road must be walked step by step. At this stage, his small goal is to pacify Liaodong.

Cheng Yuanzhi knew that the failure of the Central Plains Dynasty to conquer the Korean peninsula was not because of how strong the regime on the peninsula was, how impenetrable the culture was, nor was it because the distance was too long.

But because of three natural dangers.

As long as you figure this out, you can understand why the Gongsun family was able to dance in Liaodong for 50 years in the original time and space.

If the Central Plains regime wants to reach Liaodong and the Korean Peninsula, it needs to go through many natural barriers. Roughly speaking, it can be divided into three types of natural barriers.

The first is the Liaoxi Corridor.The Liaoxi Corridor is sandwiched between the Mongolian Plateau and the Bohai Sea. It is about [-] miles long and [-] miles wide. It is the main throat from the Central Plains to the outside of the pass.

This main road is called the Liaoxi Corridor.

At the same time, the Liaoxi Corridor is also the key point where Gongsun Kang's [-] sailors want to attack the Hebei army and cut off the food road.

The most important thing is that the [-]-mile-long Liaoxi Corridor was many times more difficult to walk in the late Han Dynasty than in later generations.

Due to the different climate and environment in this era and the lack of construction in the Eastern Liaodong region, the Corridor in the Western Liaoning has been in a muddy state for a long time during the summer and autumn rainy seasons, making it difficult for vehicles and horses to move.This makes the passage of the army and logistical support a difficult problem to solve.

In the original time and space, when Cao Cao marched north to Wuhuan, because Wuhuan guarded this road, the army could not move forward, so he was helpless.Finally came up with a way to ask Tian Chou to lead the way, bypassing the Liaoxi Corridor from Lulongsai, and marching five hundred miles along the mountain road to Liucheng.

Although Cheng Yuanzhi already took control of Liucheng during the previous sweep of Wuhuan, and this main road was already within his jurisdiction, the danger still existed.

If this road is cut off, it means that Liucheng has become an isolated city, and the food route for the 40 expeditionary troops has been cut off.

The second most important natural danger is Liaoshui.

After crossing the first natural barrier, enter the Lower Liaohe Plain,

During the Han Dynasty, the Liao River often flooded, so it was called "Liaoshui".Under its perennial erosion, a large swamp with a width of more than [-] miles from east to west was formed to the west of Liaoshui River, called Liaoze. Although the scope of Liaoze has been shrinking due to environmental and climate changes in later generations, it was not until the period of the Republic of China that a large number of immigrants entered the Guandong. It disappears completely after development.

In the current era, Liao Ze is an insurmountable natural danger.

When Emperor Taizong of the Tang Dynasty was campaigning against Goguryeo, he passed through Liaoze on the way back and forth. In order to pass through this area, Yan Lide and Changsun Wuji successively carried out large-scale road filling and bridge building here, so that the army could pass through.

Moreover, the Liao Ze is not limited to swamps in this area. There are also large swamps connected to the mouth of the Liao River flowing into the Bohai Sea. Therefore, the army usually can only choose to cross the swamp through the Liao Tunnel in the middle.

Gongsun Kang knew this well, so he set up a moat for tens of miles around the Liao Tunnel, and stood in a stalemate with Cheng Yuanzhi here for more than a month, repelling many Han army attacks.

Cheng Yuanzhi had already prepared for this. Out of the 40 troops, there were [-] civilians and engineers who would open roads in the mountains, build bridges in the water, fill in the soil, and forcibly fill in a road to Xiangping.

And finally defeated Gongsun Kang, besieged in the seaside city.

And if you want to continue to conquer the Korean Peninsula, you will have to face the third natural danger next.

After crossing Xiangping (Liaoyang), there is a rolling six hundred li mountainous area. Only by crossing mountains and rivers can we reach the Pyongyang Plain.

Later Emperor Yang Guang of the Sui Dynasty conquered Goguryeo several times. The last time he conscripted an army of one million, half of them were civilians who built bridges and opened roads.

Although the main force of 40 has won consecutive battles all the way, it still ran out of food due to logistical problems, and was finally defeated by Ulji Mundeok. Only 40 of the main force of 700 fled back.

More than 30 years later, when the Tang army marched eastward to Goguryeo, they buried a large number of Sui soldiers whose bodies were exposed in the wilderness along the way.

During Li Shimin's period, he also defeated Goguryeo three times, causing a devastating blow to it, but he failed to complete the destruction of the country. Moreover, the Tang army suffered huge losses in all aspects, especially horses.

Even during the Wanli period of the Ming Dynasty, Japan invaded North Korea and the Ming Dynasty sent troops to support it, but logistical problems prevented the army from completing its assembly and entering North Korea to fight.

It can be seen that the third natural barrier is difficult to overcome, and these three natural barriers are the biggest stumbling block hindering the expansion of the civilization of the Central Plains to the east.

Limited by conditions and time constraints, Cheng Yuanzhi only ordered people to capture the original three counties in Liaodong this time, and did not march into the Pyongyang Plain. He only controlled three of the four counties under Gongsun Du's jurisdiction, and subsequent affairs could only be managed slowly.

Yingkou is a seaside city.

At this time, Gongsun Kang finally realized how brave the Han army was, and how handsome Cheng Yuanzhi was.

Not an opponent at all!

At this moment, the regret in Gongsun Kang's heart was like the flood of the Liaohe River, and it was out of control.

He did send troops to cut off the Liaoxi Corridor, hoping to defend it until the Han army ran out of food and retreated.

But he miscalculated, the food road of the Han army was not broken.

Gongsun Kang guessed that there must be another grain road on the plateau, which was continuously transporting grain to Liaodong.

Otherwise, it has been half a year, how could the 40 Han army still have food?

No wonder his father told him repeatedly before his death that he must never provoke the Hebei Army or Yuan She.The [-] cavalry and [-] sailors in Liaodong are not opponents at all.

For the current plan, the only way is to recall the navy, abandon the city and retreat into the Bohai Sea, and find another place to hide.

It is impossible to occupy the north again. At a glance, it is all the territory of the big man.

Even if the situation is so passive, Gongsun Kang still has a way out, and there are still two places to go.

The question now is whether to go east to conquer the three countries of Malaysia and Korea, or to go directly to the Ryukyu Islands (Japan).

If he goes east to Ma and Han, will the Han army chase him to death?
This question must be clarified, otherwise it would be a waste of time to go there, and it would be empty to make wedding dresses for others.


Looking at the densely packed Han army outside the city, Gongsun Kang secretly said:
"I should send an envoy to find out what the Prime Minister of Han Dynasty has to say and see what conditions he has."

"For the sake of an envoy, it won't be so fierce."

"Everything is negotiable. If it is not possible, it only means that the conditions given are not generous enough."

Thinking of this, Gongsun Kang suddenly became enlightened, called a close aide, and gave the following instructions.

The envoy nodded repeatedly and went down to the city.

……

Cheng Yuanzhi received Gongsun Kang's envoy, and the two sides reached an agreement soon after several rounds of negotiations.

After Gongsun Kang paid [-] Lianfang warships and [-] naval troops, he exchanged for Daifang County (formerly a territory of Koguryo), and Cheng Yuanzhi's promise to never attack.

It was said to be a negotiation, but in fact, Cheng Yuanzhi was allowed to open his mouth, and Gongsun Kang desperately bargained for the price.

Now that the Liaodong Army has completely fallen into a disadvantage, there is only Yingkou, a coastal city left, so how can there be bargaining chips?

If no agreement can be reached, for Cheng Yuanzhi, it is just that he cannot get a navy and a large ship, which will not hinder the overall situation; but for Gongsun Kang, it is an unacceptable situation.

If they can't reach an agreement, they can only flee for their lives overseas.

It was hard to leave his homeland, and Gongsun Kang really didn't want to go to a wild place like the Ryukyu Islands.

The place in Goguryeo is okay, barely making a living.

After the negotiation between the two parties was reached, the Han army withdrew the besieging soldiers and let Gongsun Kang leave on his own.

However, Gongsun Kang did not go on the dry road. After leaving behind [-] large ships and [-] sailors, he left Liaodong by water. place.

……

After Cheng Yuanzhi arranged all the affairs in Liaodong, as well as the officials and defenders of the three counties, he returned to Beijing in the winter of the ninth year of Jian'an.

There was no massacre of the city, no relocation of people into the customs, and no pursuit of Gongsun Kang.

On the day when the squadron returned to Ye, 30 troops left Liaodong in a mighty manner with their banners covering the sky and their spears like a forest of thousands of horses neighing together.

It was almost the end of the new year, and I just returned to Yecheng, and each returned to the station to rest.

In Yecheng, the prime minister's mansion held a grand banquet.

The civil and military forces of Hebei gathered together to celebrate the prime minister's return from victory.

Now that the northern border is flat, the next step is to imagine how to calm down the south of the Yangtze River.

Thinking of this, all the civil and military people are full of enthusiasm and pride.They all feel that following this lord has a future.

Maybe he can leave a name in history!
