Beginning on 25 October, the Yamen of the Beiyang Naval Division issued a ban on navigation in the waters of Bohai Bay, Luda, and Weihaiwei, and the ships of the Beiyang Naval Division began large-scale operations in the waters around the Lushun and Weihaiwei naval bases to drive away all ships.

Among them, there are many great powers, but in order not to give the spy ship a chance, Wang Chenhao persuaded Li Hongzhang to offend the great powers first.

At the same time, Wang Chenhao drove the Jiaolong to Incheon Port alone every other day to investigate and find out the situation in Incheon Port.

At this time, Wang Chenhao is no longer an ordinary military enthusiast, he shoulders a greater responsibility, which is related to the survival of Beiyang sailors.

Before leaving, Ding Ruchang and Yang Shixiang always gave Wang Chenhao a systematic military theory course, and explained a series of details that needed to be paid attention to during the trip to Wang Chenhao.

As a commander, not only military excellence, but also astronomy, geography, social sciences, humanities and other aspects must be taken into account, and ordinary people without these foundations cannot become excellent commanders.

Fortunately, Wang Chenhao had a wide range of knowledge and a solid foundation, and he soon spied on the way of conducting and basically met the requirements of Ding Ruchang and Yang Shixiang, so he was relieved to go to Incheon.

The port of Incheon is located in the middle of the west coast of North Korea, only 32 kilometers from Seoul, and its biggest feature is that it has a large tidal difference, with a maximum drop of 10 meters, ranking second in the world. In addition, the tide time at Incheon Port is also the most special in the world, with only one menstrual holiday (Manchu) every month, and the full tide time is only three hours each in the evening and the next morning.

Due to the large tidal drop, if the two giant ships of Jeongjin participated in the bombardment of Incheon Port, they had to enter at high tide and leave before low tide the next day, otherwise they would have to fall into the boundless quagmire of Incheon Port and wait until the tide of the next month to come out.

The lightning strike fleet of the Beiyang Naval Division was used to attack the warships at anchor, but the military supplies needed for the invasion of China were piled up on the docks on the shore, and these had to be destroyed by the artillery of the capital ships of the Beiyang Naval Division. Therefore, if the two armored iron battleships in Dingzhen were missing, the effect would definitely be greatly reduced, so Ding Ruchang chose to let the second ship participate in the operation.

This necessitates the study of the astronomy and geography of the port of Incheon.

After studying the tide times of September at Incheon Port on September 15, October 13, November 5 and December 4, Ding Ruchang decided to launch a surprise attack and retreat on the two tides from the night of November 4 to the morning of November 5.

The time must be pinched very accurately, otherwise the warships of the Beiyang Naval Division are in danger of running aground, which also makes Wang Chenhao's task extremely heavy, but it greatly exercises his ability.

In the following days, Wang Chenhao piloted the Jiaolong to draw a map of the army's fixed mine defense around the port of Incheon. The location, depth, and size of all the mines were marked, and the reefs and shoals were also detected by ultrasonic, so that the Beiyang Naval Division fleet could safely approach the waters off the coast of Incheon Port, and the remaining work was to wait until the night of the operation to remove the small number of mines randomly placed on the main channel by the army that day.

After that, Wang Chenhao circled around Incheon Port twice, recorded the number, model, and berthing location of the warships and troop carriers of the Navy, and then left Incheon Port.

The main channel of Incheon Port is called Feiyu Gorge, which is 90 kilometers long, and there is only one main channel, and the navy does not think that the Beiyang Naval Division will easily dare to raid Incheon Port, because the battle line is too long, and the area of the nearby sea surface siltation area is more than 120 kilometers, and one accidentally falls into it.

Wang Chenhao found out that the army would temporarily arrange 8~14 random mines every night. After Wang Chenhao's observation, he found that the channel was 2 kilometers wide and the water depth was 10~18 meters, and as long as a warship was sunk by a shell from the Yuewei Island Battery, the entire channel would be blocked.

Therefore, the Yuewei Island fort guarding the channel was very important, so Wang Chenhao went around the vicinity of Yuewei Island a few times, observed the work and rest time of the guards, the position and frequency of patrols, etc., and recorded them one by one. At the same time, he observed some blind spots before returning.

With these records, Ding Ruchang can arrange for the assault team to sneak attack the Yuewei Island and defend it, once the Yuewei Island is occupied, it is equivalent to solving the second major raid problem.

In the following days, after several re-examinations, Wang Chenhao finally helped the Beiyang Navy Division solve all the problems and solutions to the raid on Incheon Port.

On November 2, the Zhenyuan ship was repaired and sailed out of the dock and reorganized into the main fleet. Prior to this, Wang Chenhao led the mine fleet to dismantle all the mines placed by the ship outside Port Arthur.

On November 3, Weihaiwei and Lushun lifted the stricturo, strictly prohibiting anyone from entering or leaving, shutting down the telegraph office, prohibiting anyone from sending newspapers for any reason, not even using electricity, and not a single bird being released.

It was Wang Chenhao's idea to be so strict, because only Wang Chenhao knew that the depth of the spy lurking in China was rare in the world, and some had been lurking in China since their grandfathers, and the balance of victory and defeat in most wars in the world was actually decided by intelligence personnel.

At 4 o'clock in the afternoon, Ding Ruchang summoned all the officers and soldiers of the Beiyang Naval Division to give a lecture and do pre-war mobilization. At the mobilization meeting, in addition to managing the mine fleet, Wang Chenhao was promoted to the commander of the Chinese Army of the Naval Division and became the deputy commander-in-chief of the operation.

This is the first time that Wang Chenhao has appeared in front of all the officers and soldiers of the Beiyang Naval Division, the base garrison, etc., and has been watched by tens of thousands of people.

At 7 o'clock in the evening, the northern sky was already dark, and the Beiyang Naval Division sailed out of Port Arthur with the whole fleet under the cover of night.

Among them, most of the 26 torpedo boats were carried by the main ships of the Beiyang Naval Division, and the remaining few torpedo boats and Wang Chenhao's mine fleet, including the "Kuaima", "Haima", "Pole Mine", "Mine Guard", "Mine", and "Mine Patrol" ships, were carried forward by the Beiyang Naval Division's auxiliary ships "Haijing", "Meiyun", "Chaohai", "Xizhao", "Jieshun", "Tielong", "Feilong", "Kuaishun", "Yushun", and "Lishun". In addition, the communication ships "Feiting" and "Feiyan" reconnoitred along the way, and two coal carriers and ammunition ships, including "Liyun" and "Baofu", followed.

This operation dispatched almost all of the Beiyang Naval Division and part of the family background of the Nanyang Naval Division, which can be described as huge.

With such a huge fleet pouring out, Ding Ruchang did not dare to go along the near sea, so he could only advance along the middle line of the Yellow Sea in the far sea, and quickly disappeared in the cold night.

At noon on the 4th, the entire fleet of the Beiyang Naval Division sailed to the depths of the Yellow Sea, 150 kilometers south of Incheon Port, waiting for nightfall.

During this period, Wang Chenhao drove the Jiaolong submarine to patrol around, and used the radar system inside to help the Beiyang Naval Division guard the ships in the surrounding waters. If a ship approached, the Beiyang Naval Division had to be transferred immediately.

Perhaps because of the war, there were very few ships in the Yellow Sea, and only two fleets passed by until dark. During this period, there was a patrol by the warship, but the Beiyang Naval Division successfully avoided it under the early warning of the Jiaolong and was not discovered by the ship.

After dark, the Beiyang Navy dared to approach the sea in the direction of Incheon Port. Because at this time, the long column of black smoke emitted from the warship had already melted into the night, and the ships of the Beiyang Naval Division were painted with gray warship outfits that were 10 years ahead, and it was difficult for the enemy to find them at night.

On November 4, the high tide was between 10 and 12 p.m., and during this time, the Beiyang Navy Division would storm the port of Incheon and destroy the warships and troop transports moored inside.

Prior to this, Wang Chenhao piloted the Jiaolong to command six minesweepers, namely the "Fast Horse," the "Seahorse," the "Pole Mine," the "Mine Guard," the "Mine Launcher," and the "Mine Patrol," and began to quietly clear the mines on the main channel.

Wang Chenhao drove the Jiaolong to hold up the mine anchor from underwater, and the officers and men of the mine battalion separated the iron cable from the mine without much effort, and then gently pulled away the mine, leaving the main channel and running aground on the shore.

At the same time, a commando team of 500 people sent by Ding Ruchang quietly landed on the west side of Yuewei Island, which was the best landing point after Wang Chenhao's observation and also a blind spot for the army's patrol.

Then, according to the patrol schedule provided by Wang Chenhao, the commando team took advantage of the opportunity of about 10 minutes of patrol loopholes when they handed over, and quietly touched up to kill the guards on duty in a silent killing manner. Subsequently, the commandos touched several outposts on the periphery one after another, and successively killed the sentinels arranged by the army on Yuewei Island.

After dealing with the enemy forces on the periphery, in less than an hour, the remaining more than 100 devils in the dormitory were also silently wiped their necks, and went to find their Aunt Amaterasu in their dreams.

After the assault team took control of Wolmijima, they filled eight fortress guns with gunpowder just in case, and as soon as the battle began, they immediately blew up the fortress guns.

After the capture of Yuewei Island, Ding Ruchang breathed a sigh of relief and immediately ordered all ships to unload all 26 torpedo boats, and unload torpedoes from the ammunition ships to fill them all.

Since the torpedo boat unit was the main force of the first wave, Ding Ruchang ordered all the officers and men of the torpedo boat to first load the torpedo into the launch tube, and then they could bring an extra torpedo on the torpedo boat for backup, so as to increase the success rate of the attack.

After everything is ready, it is time for Wang Chenhao and his mine fleet to complete the cleaning of the main channel.

Since the main channel is 90 kilometers long and the tide time is only about three hours, Wang Chenhao must clear the main channel before 10 o'clock.

Fortunately, the Japanese army was preparing the ships needed for the landing force, and in order to hurry up and let the ships leave the port of Incheon quickly, the Japanese army's minelaying boats reduced the number of mines. At the same time, they did not think that the Beiyang Naval Division would dare to come, so only a small number of temporary mines were laid on the main channel at night, and only 12 were arranged tonight.

The army was not stupid, they also thought that the Beiyang Naval Division might come to attack Incheon Port. However, in their opinion, with the demining ability of the Beiyang Naval Division, it is impossible to clear at least the dawn of the twelve mines randomly placed on the 90-kilometer-long channel, and then it is impossible to sneak attack.

It's just that they never thought that Wang Chenhao's Jiaolong could not only explode the chrysanthemums of their warship, but also easily detect the location of each mine, and even remove it easily.

At half past nine o'clock in the evening, Wang Chenhao's mine fleet cleared the main channel and placed channel buoys to guide the fleet forward.
