Underwater ghost conception

True submarine adventure novels are interesting and thrilling. In fact, the beginning of the submarine and its development were not easy, but they had to overcome various difficulties and dangers. In other words, the story of the submarine's development is like an adventure novel for children.

For centuries, humans have dreamed of building a “stealth” warship that would be invisible to enemies, a warship that could sail silently underwater and attack enemies in secret. But that dream has proven difficult to realize. It took a long time to build a submarine. It has faced many dangers. It has faced various disasters. But it has also been fraught with funny incidents from time to time.

First submarines

Stories of ships descending to the bottom of the oceans date back to 332 BC, but it was not until 1678 AD that we found concrete evidence. In the 200 years before 1775, there were 17 submarines. But none were successful. It was not until the end of the 18th century that practical models appeared.

An American student named David Bushman invented a way to detonate explosives underwater. He did this during the American Revolutionary War (1775-83), when Americans were fighting the British. Bushman needed an underwater ship that could carry the bombs he had invented.

So he decided to build a ship. This invention was called the Sea Turtle.

The sea turtle is a large wooden egg, 7 feet deep and 5.5 feet wide. It is named after the shape of two turtles joined together. It has a watertight door and three small glass windows.

Only one person can ride in it, and its tasks are numerous. To submerge it, you have to open the water tank with your foot. To resurface, you have to pump the water out of the tank with a hand-held pump. To move forward, you have to turn the handle that turns the propeller. At the same time, you have to hold the handle to get to your destination. Then, all the while, you have to look out the glass windows and observe the surroundings.

The foam bomb is tied to the back of the seaplane. The shell has explosive lines and is equipped with a thirty-minute fuse. It has a steel spike. It can be driven into the hull of an enemy ship.

A sergeant was chosen to undertake the first of his dangerous underwater adventures. He set off in a sea turtle at dawn. The first part of the mission went smoothly. The sergeant managed to navigate his submarine to the hull of the British warship HMS Eagle. However, he encountered a major obstacle. The ship's hull was lined with copper to prevent damage. He was unable to get the tip of his foam bomb into the copper. After much effort, he finally gave up and returned to his base.

He had to put the sea turtle in the water to get to a safer beach. It was getting light at that time, and some British soldiers saw a strange vehicle on the water. The enemy soldiers were following him in a boat.

The sergeant had been carrying a heavy mine in his boat until then. He dropped the mine into the water so that the sea turtle could paddle faster. When the enemy soldiers saw a suspicious object approaching them, they stopped following the sergeant and gave up.

Thirty minutes later, the sergeant fired the bomb. No enemy ships were hit. However, the explosion was so powerful in the water that the British ships were terrified and moved to safety.

He tried again to attack the British warship Saviour. But this time he was also unsuccessful. Eventually, Buchanan was forced to abandon his experiments due to lack of government support and financial resources.

Nautilus

Twenty years later, another American, Robert Zultan, invented a new type of submarine. With the American Revolutionary War over, Americans were no longer interested in "submersibles." Fulton tried to sell his design in Europe. In 1800, Napoleon Bonaparte, the ruler of France, was interested in Zultan's idea and provided him with sufficient funds to build the submarine.

The Nautilus's body is cigar-shaped, measuring 23 feet 4 inches long and 10 feet wide. It can carry about three people. The hull is made of iron and is covered with red tin. It can dive up to 20 feet underwater.

At the front, there is a large entrance porch. The porch has a glass window that allows you to see around. It looks a bit like a modern submarine's deck. In addition, the Zultan is equipped with a mast and a small sail, disguised as a Nautilus. In 1801, Napoleon watched with interest as he made his first test run on the Seine River. Zultan and two companions filled the tank to its full capacity and then dived 25 feet underwater. They remained in the shallow water for about twenty minutes, as the strong current slowly pulled them out to sea. They then resurfaced and returned at a speed of two knots per hour.

Napoleon wanted to see the Nautilus sail under water, so he gave her a small subsidy. He wanted to install thick glass windows. This would eliminate the need for candles for lighting and provide more valuable oxygen. At the same time, a compressed air tank was installed, which would allow the ship to stay underwater for up to four hours. In order to test the Nautilus underwater, Sultan also invented a new missile from his bag, which resembled the foam bomb that Bush had made. He called it a torpedo. It was named after a type of fish called a toad, which had a slender body and could electrocute enemies. Fulton wanted to test this weapon at the same time in the harbor of Brescia.

Zultan's target was an old ship anchored a short distance from the dock. The Nautilus approached the ship. It dived underwater. It loaded a torpedo on the ship. It then successfully blew the ship to pieces.

Napoleon was particularly interested in this. This weapon was the best weapon to attack the British Navy. Many French scientists agreed with Napoleon and agreed to provide the Sultan with enough money to build a real submarine. However, Napoleon's naval generals were not very interested. They considered using a gun-equipped torpedo boat to shoot a man in the back.

While the generals were debating, Sultan tried to test Nautilus's abilities by attacking the British naval blockade ships. Nautilus, taking advantage of the darkness of the night, approached the enemy ships twice. However, Nautilus's underwater speed was so slow that the enemy ships moved away before they could reach attack range. In the end, Napoleon decided not to continue supporting Sultan's invention.

By then, the nautilus had been dead for over a year, eating saltwater and taking in water. Finally, Zultan scrapped his submarine and sold it for scrap metal.

David

Sixty years later, the idea of ​​a submarine was revived. During the American Civil War, the Union forces in the North were well-equipped, especially at sea. Their southern opponents, the Confederates, were short of money to buy weapons. They needed to quickly ship the cotton that was piling up in the harbor to make enough money.

Union ships patrolled every port and attacked cotton ships as they departed. They also attacked incoming arms ships. The Confederate forces had to attack and clear the enemy ships that were blocking their way. They had to devise every possible means of doing so.

In 1864, an inventor named Theodore Stoney cut the top of an old warship down to the waterline. He then covered it with iron sheets. He installed a small steam engine that powered a two-bladed propeller.

The steam had to be discharged through a closed pipe, so the ship could not dive completely underwater. He named his ship the Pit (after David, who had defeated the giant Wally). It had a 60-pounder mounted on the top of a wooden pole. This was called a mast torpedo. The Davis, which looked little like a ship, set out to attack the Union ship USS New York, which was anchored near Culston. A sailor from the Ironside saw it and opened fire.

However, the captain who was supervising the Davis was given permission to attack the Ironside with his torpedo. The Ironside was badly damaged. The explosion also damaged the Davis. The captain decided to surrender. However, he did not have the chance. The sailors on the enemy ship were so terrified that they jumped overboard. The captain was able to rescue his crew from the water and steer the Davis back to base.

The Union forces were particularly shaken by this attack. Although the Ain Thin Sot had not sunk, they were very worried about the sudden attack. When would the strange torpedo boat come? Where would it strike? Their warships were prepared to leave at any time. The barrages were doubled.

In fact, the Confederate forces were
