Black cattle are rampant in South America.
Sisi's Free Corps attacked on all sides, and the fighting soon spread from Guyana and gradually penetrated into central South America.
Colonial armies from various countries began to encircle Saisi, and many of them saw the opportunity to beat up the colonies of other countries.
In the Caribbean, France's colonial sailing ships retreating to North America encountered surveillance and artillery fire from the British Royal Navy near the Cayman Islands.
Near Orlando, an army team from the United States and France escorted a secret weapon into the sea along the coastline.
This is a submarine!
The development of submarines can be traced back to the 16th century.
In a 1562 book, two Greeks were rewarded by the Roman Emperor Charles V for performing a feat of "driving without getting wet" while seated in a wooden submersible.
The authenticity of this incident may be doubtful, but the concept of the submersible has survived ever since.
In the next two hundred years, various countries designed more and more submersibles and produced many physical objects.
In 1776, during the reign of Emperor Qianlong and while Washington was still alive, American craftsman David built a small round egg-shaped submarine "Turtle".
She successfully nailed a mine to the bottom of the British Empire's "Eagle" battleship. Unfortunately, the mine did not explode.
The next year, the "Turtle" attacked again, attacking the British Empire battleship "Cerberus".
It was even more unfortunate this time. While approaching the "Cerberus", the "Turtle" accidentally encountered a British small boat and exploded.
The "Turtle" set a record for the first submarine kill in history, and also became the first submarine in history to blow itself up.
The United States has a relatively early history of building submarines.
First, it comes from the exploratory spirit of the colonists, who are relatively receptive to new things.
The second is to fight against the increasingly powerful Royal Navy of the British Empire.
The new United States of America was still very weak, and neither the army nor the navy could carry the banner of independence.
Historically, the Presidential Building has been broken into and burned down many times by neighbors.
In order to cover up its dark history, the United States of America painted the Presidential Building white and renamed it the White House.
In this era, if the United States wanted to deal with the colonists of the British Empire, it could only take an unusual path and conduct asymmetric warfare.
In 1797, American genius inventor Robert Fulton submitted a submarine plan to France, and the result was the Nautilus submarine.
It was completed in 1800 after Qianlong's death.
As we all know, France supports the United States of America as long as it opposes Britain.
The later Statue of Liberty was a gift from France to the United States of America.
Regarding causing trouble for the Royal Navy of the British Empire, France gave full play to its fine traditions and vigorously supported the United States in building submarines.
In early June, the sun was shining brightly.
After learning that many French sailing ships evacuating the colonies were intercepted by the British Empire, France could not sit still.
Napoleon provided the United States with new technology derived from the explosion fuses of the Ming 240 siege heavy artillery shells, and a new generation of mines were created.
On this day, Captain Nemo and three crew members entered the Nautilus amid the expectations of both armies.
This small submarine with an iron frame and a copper hull is 7 meters long. It carries two mines and is controlled by four people.
She has a folding mast and can be propelled by sails on the water and hand-cranked propellers underwater.
On the bracket on the bow of the submarine, there are two modified spike mines.
blue sea, blue sky.
Nemo and the four men raised the folded sail and headed southwest in the Caribbean Sea.
A few days later, the bored Nemo and others finally discovered a battleship of the Royal Navy of the British Empire on the sea skyline.
Fortunately, it is still the old enemy "Cerberus".
"At this distance...retract the sails and dive!" Nemo estimated the distance and course of the two sides and ordered the crew to start taking action.
The folding sail was stowed and fixed on the upper deck. Everyone entered the submarine, carefully inspected the watertight compartment, and began to dive.
At this time, the submarine cannot fully dive.
After the Nautilus dives, the raised viewing window above remains above the water for observation.
The observation window and the folding sail on the back "float" on the sea, looking like waste from a distance.
It's 2pm.
The huge body of the "Cerberus" sailed past this "floating object", and no one cared about such marine garbage.
It was not until the Nautilus nailed two mines to the side of the Cerberus that the sailors of the British Empire discovered anything unusual.
They only felt that the ship's hull seemed to have hit the rocks.
"See what's going on?"
"What the hell is this?"
"There's someone inside!"
British Empire sailors sighted the diving Nautilus.
I saw the Nautilus slowly moving backwards under the desperate shaking of the crew.
The Cerberus was sailing under full sail and quickly passed by the Nautilus.
Sailors from the British Empire could see through the observation window of the Nautilus that there seemed to be people inside.
He also gestured "yeah" to them.
Can this be tolerated?
The captain of the Cerberus was just about to order the sailors to release the boat to teach this ghost a lesson.
Suddenly, the mine exploded.
The two mines were replaced with fuze structures of 240 heavy artillery shells. When the mines left the steel frame of the Nautilus, the internal coiled spring device that was disassembled from the Sachen clock began to operate.
After a few minutes, the mercury fulminate excitation device was activated and the mine exploded.
The huge explosion rocked the Cerberus.
Although the improved version of black powder has only the same explosive power, it cannot withstand the large amount of powder charged.
Two mines directly opened a huge hole on the side of Cerberus.
The water rushes in like crazy.
The sailors from the British Empire came to the cabin below carrying wooden planks and hammers, and were stunned to see the huge hole with a diameter of five to six meters.
They threw down a wooden board that was less than one person high and ran back to the deck like crazy to report the situation.
Generally speaking, in naval battles at this time, the damage suffered by battleships comes from naval guns.
However, the caliber of the naval gun is limited, and it will only make holes in the battleship.
Gaps can easily be filled using wood planks and waterproofing vegetable colloid.
However, the damage caused by mines cannot be repaired with current technology. We can only rely on the watertight compartment at the bottom of the ship.
Unfortunately, the Nautilus dived relatively shallowly, and the mines were almost placed close to the waterline.
This also led to the fact that the Cerberus could not be saved at all.
Sea water continued to pour in, and the Cerberus sank at a speed visible to the naked eye.
British Empire sailors released lifeboats and jumped into the water to save themselves.
In the distance, Nemo, the captain of the Nautilus, looked at all this, his eyes widening.
The results are brilliant!
However, now is not the time to relax.
After all, those released boats are also capable of fighting.
The four Nemo men quickly shook the floating handle. After floating up, the two crew members got out of the submarine and unfolded the folding sail.
Finally, the Nautilus flew away from the scene of the accident amidst the anger of the British sailors.
