Captain Guan Youzhi has always mastered the telescope and led the submarine fleet to dive under the sea to avoid ships on the sea.
The submarine can retract the snorkel and rely on the air in the submarine to dive to a depth of tens of meters.
But the compressed oxygen stored in the submarine can only last for two hours.
When the time reaches two hours, you must ventilate with the outside world.
The oxygen in the high-pressure cylinder is basically exhausted, and a large amount of carbon dioxide will accumulate in the submarine, causing people to become comatose.
Guan Youzhi is very confident in the submarine's ability, unless it has no choice but to surface due to mechanical failure.
The submarine only needs to release the mines and does not engage with enemy ships at all, so safety is guaranteed.
The time when the submarine makes an emergency dive can also allow Guan Youzhi to command the submarine fleet and escape from the enemy's encirclement.
In order to be able to sneak underwater, submarines do not have armor similar to battleships.
Once the submarine is exposed, only one depth-fixing mine is needed to sink the submarine to the bottom of the sea forever.
The submarine is like a ghost, moving forward in the Mediterranean Sea.
The sky has completely darkened, and the submarine is still moving forward at night through the stars and islands.
Captain Guan Youzhi handed over the navigation work to the fleet chief of staff Xing Shuiyun.
Submarines are like ghosts, moving forward in the sea.
At a fixed time every day, he received telegrams from the Fujian Navy to understand the current situation.
Captain Guan Youzhi glanced at the time on the telegram.
Year 4356 (1659 AD), October 25th, 3:21 in the morning.
Two days ago, the Vietnamese army had completely eliminated the defenders of Danji Port.
After a day of rest and recuperation, they are now ready to evacuate most of the troops, leaving only some of the garrisoned troops.
Twelve submarines have now arrived in the Strait of Gibraltar and are preparing to start laying mines.
Captain Seki Yushi conveys the fleet's combat orders to each ship through divers.
“The Vietnamese navy has not yet withdrawn its troops from Danji Port.
Our task is to lay a large number of mines around Tangji Port.
Never lay mines in the Port of Gibraltar to affect the Imperial warships.
The number of mines we carry is limited. The principle of laying mines this time is to seize the big ones and let go of the small ones.
The depth of laying mines will only destroy warships above cruisers.
There are no mines in the Strait of Gibraltar, so we immediately went to Vietnam's main military port to lay mines.
We do not seek to destroy or damage large Vietnamese warships with mines.
As long as we can block the large Vietnamese warships in the port for a few days, our fleet will be able to cause enough casualties to Vietnam."
The Fujian Navy's strategy for this counterattack is very clear.
By laying mines through the submarine fleet, if there is enough time, mines will be laid on the return route of the Vietnamese navy warships, blowing up several warships and avenging the sacrifice of the compatriots in Danji Port.
At the same time, mines were mined outside Vietnam's main military ports to delay the departure of large Vietnamese warships.
The Fujian warships could take advantage of the time when the Yue warships were unable to leave the port and inflict a lot of damage to the Yue State.
The purpose of Fujian's counterattack this time is to tell European countries that it is by no means a soft persimmon.
Fujian must demonstrate its military's strong combat capability to the outside world.
Captain Guan Youzhi led the submarine fleet and has arrived outside Danji Port.
He saw the lighthouse built by the Fujian Kingdom indicating the location of the port.
There are a large number of Vietnamese warships and ships moored in the port, with faint lights flashing above them.
Captain Guan Youzhi saw that the submarine fleet had arrived at the designated location.
He immediately gave the order excitedly.
"Deploy mines in an orderly manner according to the plan."
The submarine fleet followed previous training. They set the position of the mine, released the mine fuze safety, pushed the mine through the sealed cabin, and pushed it out of the submarine.
The mine immediately floats to the set water depth.
The submarine continued to move forward and laid the next mine.
Captain Guan Yuzhi has been observing the situation in the surrounding waters through the periscope.
He has always been worried about the submarine fleet being exposed.
This is the first time a submarine fleet has participated in actual combat.
Problems that are not discovered during normal training are likely to be exposed in actual combat.
This is not the first time that submarines have appeared on the battlefield. Who knows if any submarines have been discovered.
The plan to lay mines went smoothly.
Captain Guan Youzhi showed a happy smile and continued to command the submarine fleet to cross the Strait of Gibraltar and go to other Vietnamese ports to lay mines.
…………………………
Port of Gibraltar, home of the Imperial Mediterranean Fleet.
Governor Hyten was sleeping soundly. He heard a clear knock on the door and immediately woke up from his deep sleep.
A subordinate came to disturb his rest. This must be an emergency.
Governor Hyten was walking and getting dressed. He glanced at the clock on the wall. It was now around three-thirty local time.
He opened the door, and his staff officer Hu Dongdong said excitedly: "Mr. Governor, the sonar has detected something going on in the waters around Danji Port."
When Governor Haiteng heard the report, the fatigue on his face disappeared and he immediately became energetic.
"Is there really something wrong with the sonar?"
He saw staff officer Hu Dongdong nodding and quickly rushed towards the sonar room.
Governor Hyten has full confidence in the capabilities of sonar.
This is equipment just put into use by the Imperial Navy.
On land and sea, telescopes can be used to detect enemy forces.
The Navy has always wanted to find equipment that can detect what's going on in the ocean.
Especially the submarine service of the Imperial Navy, a combination of submarines and torpedoes hidden in the sea.
It can sink the Empire's most advanced battleships silently.
The submarine's results in the exercise made many naval generals panic.
The Navy immediately decided to increase investment in marine reconnaissance equipment.
Sonar, a device that uses sound to detect ocean conditions, was developed.
Sound as a means of investigation has been used thousands of years ago.
The ancient cavalry could put their ears to the ground and judge the size of the enemy army based on the sound of horse hooves.
There were several large vats inside the ancient city walls, and they could collect the sound of whether the enemy was digging tunnels.
Sonar only relies on scientific methods to detect subtler sounds.
Sonar is an extremely sensitive earpiece that can hear subtle sounds in the ocean.
Governor Hyten came to the sonar room and saw that the sonar operator was wearing headphones and was concentrating on listening to the sounds collected by the sonar.
They can pick out special sounds that suddenly appear among the chaotic sounds.
There is a dot matrix printer working next to it.
It prints the collected sound signals on paper.
Staff officer Hu Dongdong took out the data collected last night and the data just now, and handed them to Governor Haiteng.
"My Lord Governor, you can make a clear judgment after looking at these two pieces of data.
In the waters surrounding Danji Port, twelve ships with similar voiceprint information suddenly appeared on the seabed."
When Governor Haiteng heard what his staff officer Hu Dongdong said, he blurted out: "This is a submarine from Fujian. I didn't expect that there are still submarines in Fujian."
The Vietnamese navy has no defense against submarines at all, and it will suffer heavy losses this time."
Staff officer Hu Dongdong said seriously: "Your Majesty Governor, judging from the experience of our army, Fujian does have hidden submarines. This is a surprise attack on the Vietnamese navy.
The two countries have declared war and sent submarines to fight. This is a normal situation.
If the country of Yue fails to discover it, it will be beaten if it falls behind.
I understood from the sound that Fujian's submarines were not like the Empire's, quietly lurking and delivering fatal blows with torpedoes.
They seemed to be laying mines, preparing to use mines to intercept the warships returning from Vietnam.
Mr. Governor, do we need to inform the Vietnamese navy of this news?"
After Governor Haiteng listened to the story of his staff officer Hu Dongdong, the nervous look on his face disappeared.
What he was afraid of was not submarines but torpedoes. Fujian had no torpedoes, and submarines lost their weapon of concealment, so they posed little threat to the Mediterranean fleet.
"The requirements for torpedo technology are very high, and it is normal that Fujian cannot master this technology.
Even if technology spreads, these countries must first obtain torpedoes before they can imitate them.
Now our Mediterranean fleet does not have submarines or torpedoes. It would be really scary if Fujian could develop it on its own.
The two countries of Fujian and Vietnam have declared war. As for the war between vassal states, without the order of the imperial court, our Mediterranean fleet must not get involved."
…………………………
General Wu Yi arranged for the troops to stay at Danji Port, and he was ready to lead his troops back.
Capturing a port in three to five days has proven the strength of Vietnam's navy and army.
Victory is an extremely powerful catalyst, allowing these new recruits to immediately undergo a huge transformation.
General Wu Yi arranged the naval fleet and troop transport ships in formation.
King Bai Yuangui of Yue has already prepared a grand welcome ceremony at the domestic port.
General Wu Yi is already making preparations to return to China.
He saw the battleship Glory, which had been seriously damaged due to the exchange of fire with coastal defense artillery.
In particular, the armor on the left front of the hull has been penetrated, revealing a huge hole.
The most serious problem is a small hole below the waterline.
Seawater continued to pour into the ship. If it were not for the watertight cabin to isolate the seawater, the battleship would sink into the water.
The battleship Glory must not be sunk. The battleship is damaged and sunk. These are two completely different consequences.
General Wu Yi decided to let the battleship Glory return to the military port for repairs first.
If the situation of the HMS Brilliant battleship is delayed any longer, it is likely that the damage will be aggravated.
General Wu Yi originally wanted the Brilliance to appear in the fleet returning to the city to show the battleship's tenacious performance in the war.
The fact that the battleship Brilliant was seriously injured and unable to leave the firing line will surely usher in the cheers of the people.
They accepted the cheers of the Vietnamese people, but the battleship Glory had no choice but to leave.
This will bring great frustration and hit the battleship Brilliant which has already made great achievements.
However, the ship's engineers determined after inspection that the damage to the battleship Glorious was somewhat serious.
It had been damaged while serving in the Imperial Navy. This time it was shelled, which may have detonated the old damage and caused the battleship's keel to break.
General Wu Yi understood this situation and could only let the battleship Glory return to China for rest as soon as possible while it was in good condition.
After the battleship Glory received the order, it immediately returned to Vietnam for repairs under the escort of three destroyers.
General Wu Yi won the victory, but he was not complacent and remained vigilant.
He ordered three intact destroyers to escort the injured battleship Glory back.
Prevent any accidents from happening to this injured battleship during its short journey back home?
General Wu Yi is sorting out the formation. Which warship can be ranked in the front is based on their military exploits.
He suddenly heard a muffled sound coming from the north.
General Wu Yi immediately turned his head and looked north. His eyes immediately turned red.
The battleship Glory was about ten miles away from the port when a mine suddenly triggered on the bottom of the ship.
This huge battleship was directly blown off course by the explosive power of the mine.
After the battleship Glory deviated from its course, it triggered a mine in the water again.
This powerful mine detonated on the vulnerable left side of the battleship Glory.
This directly tore apart the hull of the battleship Glory, and the turbulent seawater immediately poured into the interior of the hull.
The battleship Brilliant immediately began to tilt violently and kept swinging in the sea, which detonated several more mines.
General Wu Yi saw the battleship Glory sinking directly into the sea after several muffled sounds.
None of the hundreds of crew members on the ship had time to escape, and they sank to the bottom of the sea together with the battleship.
General Wu Yi could not believe what was happening in front of him.
"Why are there so many mines outside Danji Port? They are fixed-depth mines specially prepared for large warships."
General Wu Yi couldn't figure out what method the Fujian army used?
Able to approach them quickly and lay a large number of mines.
Mines are extremely difficult to deal with, and ordinary methods cannot guarantee that all mines will be eliminated.
As long as a large-yield mine explodes in the relatively fragile bottom of the battleship, the battleship is likely to suffer extremely serious damage.
General Wu Yi immediately commanded the destroyers and began to use various methods to clear the mines outside the port.
This chapter is not over yet, please click on the next page to continue reading the exciting content! Unable to clear a safe route, they dare not leave the port now.
"General, I remember that when the empire was fighting in the Mediterranean, it used steel trawls to deal with the submarines of the European Allied Navy, and quickly eliminated these submarines.
When we deal with mines now, we should be able to use steel trawls to solve them."
General Wu Yi shook his head and said: "The matter is not that simple to solve.
Unlike mines buried in the ground, mines are fixed in one location and do not move around.
However, mines are driven by sea water and can move slowly along the undercurrent of the seabed.
An area must be cleared of mines so that the fleet can pass safely."
While General Wu Yi was dealing with the mines, he immediately reported the relevant situation to the Yue King Bai Yuangui.
When the Fujian navy went out for an expedition, they did not raise their troops in anger, but were fully prepared.
Vietnam must be prepared to deal with the threat from the Fujian navy.
…………………………
King Bai Yuangui of Vietnam came to Dingzhi Port at the southern tip of Vietnam, which is very close to the port of Gibraltar.
He is preparing to hold a grand welcome ceremony here.
This is to show off the military power of Vietnam and at the same time show it to Gibraltar.
King Bai Yuangui of Yue received the declaration of war from Fujian four days ago, but he didn't care at all.
The performance of Fujian was as they had inferred, with loud voices and almost no actual actions.
When King Bai Yuangui of Yue heard that Fujian was enlarging its army, he became a little nervous.
But he was not afraid at all. If the Fujian army really dared to land, the Vietnamese army could drive them into the sea.
The Yue King Bai Yuangui didn't care before, but when he received an emergency telegram from Danji Port, his expression immediately changed.
