On the hillside, the city that turned into ruins has begun to be rebuilt, but the ruins are still filled with the smell of blood and a little smoke. They are traces left by the bombardment of artillery. The mixed strange smell drifts away with the wind, making Du Ruhui, who had just come up, feel a little nauseous after hearing this.

He was not a coward, but he was just not used to the smell. He looked at the soldiers who built fortifications and looked at the mountain city that belonged to Goguryeo not long ago. Then he looked back at the gunships anchored on the shore of the water at the foot of the mountain. He felt the power of the new artillery.

From the hill to the shore of the water, the distance from the optical rangefinder is about six miles in a straight line. If it were more than ten years ago, the artillery of the government army would not have reached such a long range.

So Gogurye chose to build a city here, thinking that he could hold on for a while under the attack of the Zhou army, but he couldn't even last a day.

Since the last battle between the two countries, more than ten years have the military technology of Zhou State made rapid progress. The range of the cannon using new types of drug-launched drugs has increased a lot, exceeding the imagination of Goguryeo.

Although the cost of new artillery and shells is much more expensive than before, the money spent by the imperial court is worth it.

The hills that were taken yesterday have begun to be redesigned today. Du Ruhui looked at the cableway that had already taken shape on the hillside and was very satisfied with the construction speed of the engineers. In a few days, the cableway will be put into use.

This cableway is a cable that is added up by iron frames. One end of the cable is driven by a steam engine (the steam engine is located at the foot of the mountain). There is a hanging basket (hook) on the cableway, which can transport personnel or materials from both ends of the cableway.

Because the cableway iron frame is assembled with standard iron parts, it is assembled very quickly and the stand-up iron frame is also very solid. This cableway was used in mines before, and its technology is very mature. It can also set up a telephone line to keep in touch with the top of the mountain and the foot of the mountain at any time.

Some soldiers drove mules and horses up the mountain, and mules and horses carried dismantled cannons, including gun barrels, gun stands, wheels, etc. After mules and horses transported these "scattered pieces to the mountain, the soldiers reassembled them into artillery positions and built artillery positions on the ruins of the mountain city.

The muzzle faces the mountain pass in the northeast direction.

There is a pass that enters and exits the stretching mountains, about two miles wide, with high mountains on both sides, about four miles away from the mountain city.

If the Goguryeo army hiding in the mountains wants to rush out of this portal and launch an attack on Pyongyang dozens of miles downstream of the water, it has to face the mountain city under Du Ruhui's feet.

So, why didn’t the official army set up camp at the mountain pass, but set up defenses on this mountain?

Du Ruhui looked at the terrain in front of him and suddenly thought of an example of war, that is, the Battle of Jieting between the Han (Shu Han) Army and the Wei Army during the Three Kingdoms period.

Jieting is in the valley, and the mountains on both sides are very tall, but there is a mountain called Nanshan, which is steep on the three sides downwards. The mountain is opposite the valley pass.

Before the war, the Han army planned to garrison troops at the foot of the mountain, establish camps on the road, guard the pass, and block the upcoming Wei army in a narrow valley. The opponent could not line up, so he could not exert his military advantage.

If you try your best to block the opponent for a while, the main force of the Han army will arrive.

However, after checking the terrain, Ma Su, the chief general of the Han army, decided to pull the men and horses to the south mountain and wait for the enemy to attack. Then the Han army condescends and defeats the enemy.

Deputy General Wang Ping felt that this was inappropriate, and he was like putting himself to death and advised him many times.

Ma Su believed that "only put it to death and live." Han Xin also violated a military taboo and won a battle with the same formation as a back-to-back. Now the soldiers have no choice but to retreat and will be able to fight hard to defeat the enemy.

The Wei army soon arrived, and the commander Zhang He was the long-time general on the battlefield. Seeing the Han army defending so much, he instantly understood what the opponent was thinking, so he surrounded the mountain but did not attack.

Although the Han army on the mountain was condescending, it could not defeat the Wei army. There was no water source on the mountain, and the people and horses were hungry and thirsty. Soon, the morale of the army was in chaos and was defeated by the Wei army.

The Battle of Jieting has always been regarded as a negative example, and later generations are taught not to talk about war on paper. Du Ruhui is very familiar with this example. Now, looking at his own arrangements, it seems to be similar to the Han army in Jieting back then.

Although the official army also set up a village at the foot of the mountain, they just didn't go to the mountain pass to set up a village to block the road. Isn't it too arrogant to be so arrogant?

Du Ruhui felt that it was not, because the times have changed. The government army has artillery, telephone, and cableway transportation devices driven by steam engines.

The camps on the mountain (including artillery positions) are connected with the camps at the foot of the mountain by telephone. The artillery can shoot the designated targets condescendingly at any time as needed.

Today he has seen the power of the cannon. As long as there is enough ammunition, the enemy will die as much as they come.

There is only a reservoir on the mountain and the hillside is steep, but with the iron cable transportation device, the food, water, ammunition and various materials at the foot of the mountain can be easily transported.

If Ma Su had a few cannons to help, the Wei army would have been defeated.

Thinking of this, Du Ruhui looked at the mountain pass again.

The area he is located in should be the former land of Siwang County in Lelang County, Han. It is on the east bank of the Wushui River (the Wushui River runs north and south here), and is about 60 miles away from Pyongyang downstream (water route). The Goguryeo army hiding among the mountains is the closest gateway to attack Pyongyang.

However, with the help of artillery, this portal was closed for the Goguryeo army, and the other party either took a long way to go, ran out of the mountains, or attacked here forcibly.

It seems that there is no village established in this mountain pass, and the Goguryeo army has the opportunity to break through, but it is actually impossible.

The reason why the official army did not set up a village at Yamaguchi was to give the other party a thought, and he was unable to make up his mind to take a detour and get out of the mountain. When he came to his senses, it was too late.

The Goguryeo army hiding among the mountains will be like a dog locked in a room, with no chance to rush out except being beaten.

This is "closing the door and beating the dog".

......

At the mouth of the Sashui River, on the shore, the old place of Fan Khan in Hanlelang County, on the south side of the Sashui Road march camp, the soldiers who had just landed were stunned when they saw a train "Wuwuwu" passing by at the simple station.

I saw clearly that the flags of the Pyongyang Road were marching on the car, and everyone found it unbelievable:

The railway connecting Fankhan and Pyongyang has been repaired? The train is open?

It has only been two months since the war started. What's going on?

The military officers in charge of military supplies at the station saw the soldiers who had just arrived and were talking, and laughed: "Why? Is it strange that the railway is opened to traffic for less than two hundred miles in two months?"

A soldier asked, "No, right? I remember that in the past years, the railway was built for five or six hundred miles, but after a year, the railway of two hundred miles would have to be built for four months."

"That's what happened before. The court has been building railways in recent years, so the skills of building railways are becoming more and more skillful, and of course the speed is getting faster and faster."

The military officer said with a smile, full of emotion: "Besides, the company has already surveyed this line. Most of them are flat ground and there is no shortage of materials for the construction. The construction starts as soon as it is said. The railway construction team is a veteran who has built the Xulai Railway. It can build twenty miles a day, so of course it is fast."

The soldiers came to the side of the railway and looked at the railway with emotion. Someone thought about it and asked, "Twenty miles a day? Then only ten days will be built after 200 miles? Isn't that right?"

The military officer disagreed: "Think about it with your brain! Doesn't it take time to build a bridge? Two months is just right, two hundred miles of railway and train to go to Pyongyang. It took only more than two hours to go to Pyongyang."

Everyone looked at the railway and the train unloading, and felt a ridiculous feeling.

As a result, the government army was fighting and building railways while fighting. It seems that this kind of tactic has never been done before?

It is said that I still farm, so I won’t say that this is necessary, but if the railway construction is done, can’t it be possible to slowly repair it after the war? Now it’s so urgent, it seems that the railway construction is also fighting.

"Did you not participate in the pre-war mobilization meeting?" The military officer began to ask these "newcomers". "The court said that this Eastern Expedition was to recover the old lands of the four counties of Han. Since it was a regain, it had to be managed with care, rather than leaving after the war."

"Railways are good things. How much manpower and animal power can be saved by transporting food and grass? Anyway, it will be repaired sooner or later. If you have to use it early, you will use it early, right?"

"We are fighting now, but the enemy has shrunk to the mountain city in the mountains. We will take the opportunity to build the railway. When they come back to their senses, it's too late!"

"With railways in the plains, the government troops deployed defenses along the line to protect the military farming teams, and then built the fortress on the important roads on the mountainside. The Goguryeo soldiers hid in the mountainous areas. If they thought about it, would it be so easy to get out?"

After saying this, the soldiers roughly understood the benefits of emergency repairs of railways. Seeing the railway tracks extending to the distance, some people sighed: "The railway has been repaired and the plains have been controlled. Then will we close the door and fight the dog next?"
