The World Online

In 1558, in the book "Wu Bian" compiled by Tang Shunzhi of the Ming Dynasty, a structure and layout method of "underwater mine" was recorded in detail to combat the ravages of China's coastal areas.

This is the earliest artificially controlled, mechanically fired anchor. It uses a wooden box as a thunder shell, a putty sticks, and a black powder is placed inside. The firing device is not tied with a long rope and is detonated by a person.

Under the wooden box, a Sevastopol rope pendant has three iron anchors to control the depth of the mine in the water.

In 1590, China invented the earliest drifting thunder - the "water dragon king cannon" with a burning fuse as a timing fuze. Nine years later, Wang Minghe of China invented the "underwater" of the ropes.

In 1621, the "underwater dragon king cannon" and "underwater sounding thunder" were improved to trigger the drifting of the lightning fuze, and many times in the naval battle to destroy the enemy ship.

It was not until the eighteenth century that Europe and the United States began to use mines in actual combat. During the North American War of Independence, North Americans attacked British warships moored at the mouth of the Trava River in Philadelphia. On January 7, 1778, gunpowder and mechanical hitting letters were placed in small beer kegs to make mines, which drifted down the river.

Although he did not encounter a warship at the time, he suddenly exploded when he was picked up by the British military squadron, killing and wounding some people, known as the "Keg War."

In the mid-nineteenth century, the Russian B.C. Yatubi invented the electrolyte to trigger the mine. In the Crimean War of 1854-1856, Tsarist Russia used this triggering mine to apply to the harbor defense. .

Since then, various types of mines have been continuously developed and improved, and are widely used. In the American Civil War and the 1905 Japanese-Russian War, the mines were quite good.

Since then, countries have paid more attention to mine warfare and invested a lot of manpower and resources to intensify research and manufacture of various mines. In the First World War, the two sides deployed a total of 310,000 types of mines, 148 ships with submerged surface ships, 54 submarines, and 586 merchant ships, totaling 1.22 million tons.

In modern naval battles, mines are an indispensable weapon. A few old-fashioned mines, which are costly, are enough to kill a modern warship costing tens of millions or even hundreds of millions of dollars.

The Mediterranean Fleet was placed in the waters of Gibraltar. It was the triggering "underwater dragon king cannon" and "water bottoming thunder" brought by Ouyang Yu. There were thousands of pieces, and the inventory of the war preparation agency was evacuated.

The mine manufacturing technology is in line with the Ming Dynasty firearms manufacturing technology. After the improvement of the No. 7 research institute, the explosive power is greater, the trigger is more sensitive, and the sea surface is more secret.

These secret weapons, Shanhaicheng, have been secretive. After the development, the Daxia Dynasty did not have any large-scale naval battles; the second was also a strategic weapon for the sake of confidentiality.

Waiting to provoke the Moroccan national war, in view of the complicated situation in the Mediterranean, Ouyang Yu decided to let the underwater dragon king cannons come out and use it in this sea battle, and it was a hit.

Although the western technology tree is ahead of the East, it is behind in mine technology. Therefore, neither Casillas nor Alexander Farnese had encountered a mine attack.

This kind of meaning, or arrogance, has brought about bitter fruit.

Although Alexander Farnese urgently ordered the warships to stop moving forward, the sailboats that could sail quickly could stop and stop.

The explosion is still endless.

A large number of warships have been hit by water mines, and the severely damaged ones are slowly sinking.

To make matters worse, for a while, the two formations of the Mediterranean Fleet quickly came over and made a line and began to fire on the Spanish Invincible Fleet.

The two formations are one south and one north, and the firepower is fully open. They are aimed at the key parts such as the sails, masts and muzzles of the enemy ships. The enemy ships have lost their ability to sail as the first target.

As mentioned above, it is difficult for a simple sail battleship to shell each other. It is difficult to obtain decisive results in a short period of time. The only way is to break the mast.

A battleship with no masts and sails, like a tiger without teeth.

Alexander Farnese was not a leisurely generation. He quickly calmed down and commanded the fleet to fight back. The narrow road meets the brave and the invincible fleet has a quantitative advantage. It is not without counterattack.

Only in this way, the Mediterranean fleet has a dominant position in the end, and it is attacked on both sides. If it is two dozens, the Spanish Invincible Fleet will be destroyed if it is not destroyed.

The change came out of Casillas, and the Casillas, who was slightly slowed down, had a lingering fear. Looking at it, the invincible fleet had sunk nearly 30 main battleships.

This loss made Casillas look pale.

The invincible fleet is the home of the whole of Spain, and it must not be defeated.

"No, you can't fight like this."

Casillas immediately reacted. If the invincible fleet was really hit hard in this battle, then the Gallic Fleet and the Roman fleet would never give Spain another chance to enter the Mediterranean.

Wait until then, it’s really desperate. In the end, the face is small and the interests are big.

"Withdraw, retreat!"

Casillas found Alexander Farnese and issued an order to withdraw his troops.

"What are you talking about?" Alexander Farnese was somewhat unbelievable.

I didn't want Casillas to be determined. I firmly said: "General, at this juncture, it is the first priority to preserve the fleet. You won't know the subtle situation of the Mediterranean?"

Alexander Farnese listened, and his expression was silent. Although not reconciled, Alexander Farnese had to admit that Casillas said it makes sense, and said with a bite: "Take it!"

"withdraw!"

Soon, the command to retreat the team will be passed on.

Regrettably, even if the Spanish Invincible Fleet wants to withdraw, not all warships can be withdrawn. Whether it was hit by a mine or the mast of the Mediterranean fleet, it could not go.

Such a warship actually accounts for one-third of the entire fleet.

In addition, the invincible fleet has entered the depths of the minefield. It is very difficult to stop at this moment and then turn the bow. In the process, it is inevitable to encounter the mines laid in the sea again.

It’s really a disaster.

Fortunately, the Spanish Invincible Fleet is a well-trained and mature fleet. From the top to the commander, down to the officers, and even the Navy and crew, they are experienced.

Therefore, although this time, even after the change, in the end, panic and chaos, a ship battleship in the bursts of gunfire to complete a gorgeous turn, collective turnaround. In the process, you can also fire back.

The heritage of the old maritime empire should not be underestimated.

Alvaro sees the enemy to withdraw, naturally will not let it go, ordered the fleet to bypass the minefield and continue to pursue. Relying on the territorial nature of the Daxia Dynasty, the Mediterranean Fleet is a little faster than the Invincible Fleet.

Coupled with the fact that the invincible fleet of warships have been more or less hit by mines, they are more likely to be caught by the Mediterranean fleet and continue to be bombarded.

A cannonball flicked across the sky and blew on the deck, making it a man.

This time, both Casillas and Alexander Farnese have a headache.

"No, you can't just withdraw it. If you consume it, the fleet will not be killed." At the crucial time, Alexander Farnese made a decision, and immediately ordered 20 warships to re-transfer the bow, end to end, With the tide of the railway, the Mediterranean fleet was chased by the route.

The remaining warships fled.

Alvaro met, sighed and looked complicated. He said, "I have escaped from it!" He was born in Spain. Now, although he is his own master, he is also intolerable with the old club.

Just how can't bear it, the fight still has to be played.

............

An hour later, the self-defeating Spanish invincible fleet finally got rid of the pursuit of the Mediterranean Fleet, once again crossed the Strait of Gibraltar and wandered to the country.

It’s really sad to rush to die before the expedition.

The whole battleship was shrouded in a gloomy atmosphere, and Casillas was ashamed of it, remembering the rhetoric before the departure, and seeing the strange eyes of other Mediterranean lords~www.wuxiaspot.com~ Casillas almost lifted I don’t have a head, I really have no face to face these allies.

Seeing that the Spanish Invincible Fleet actually ate in front of the two formations of the Mediterranean Fleet, the warships suffered more than half of the damage, and the strength suddenly decreased. These Mediterranean allies were really shocked and looked different.

From this point of view, the already strange situation in the Mediterranean is afraid of resurgence.

As for the two Moroccan lords of Caroline and Rainier, it was already a dead end. They knew better than anyone else. The last chance of victory in Morocco was completely ruined in a big explosion.

Rainier was very temperate, and he went to the temple to transfer to the temple.

Carolyn did not have the courage to be self-sufficient. He would be locked in the cabin and no longer see anyone. She was just waiting for the system to pronounce the death of Morocco, and went to the place of trial.

At this time, a ship was coming in front of the sea, which was the fifth formation of the Mediterranean Fleet stationed in the base city. According to the plan, the fifth formation is responsible for intercepting the invincible fleet.

Compared with Alexander Farnese, Alvaro still has to be skillful and accurate.

With the current remnants of the Spanish Invincible Fleet, there is no fear of the provocation of the fifth formation, and even a sure battle to win. Just stunned Casillas is no longer willing to fight, he is worried that the fleet will be dragged by the enemy, and then chased by the other two formations chased later.

By that time, under the attack of the front and back, the invincible fleet was afraid that it would be in jeopardy.

So when I saw the fifth formation, Casillas didn't even think about it. He directly dispatched 20 warships to intercept it. The remaining main forces guarded the flagship and detoured. The wolf fled back to China.

Proud Casillas, this time was completely feared by the Mediterranean fleet.
