At 1 a.m. on September 19, 1911, after a day of fierce fighting, most of the officers and men of the American fleet had already fallen asleep, and more than a dozen huge battleships were slowly sailing like hills standing on the sea. In order to avoid being attacked by submarines, these battleships did not stop sailing, but only kept their speed at about four or five knots. The course on the sea surface is also a standard zigzag anti-submarine course. Around these battleships and heavy cruisers, more than a dozen light cruisers and destroyers were cruising, and the searchlights on them illuminated the sea as if it were daylight, forming a tight anti-submarine net.

On the outermost part of the anti-submarine net, there are more than a dozen light cruisers of the American fleet. This anti-submarine net was a full ten kilometers away from the battleship, which already exceeded the maximum range of fish. On the innermost level, there are more than a dozen destroyers. Agile and faster destroyers became the last line of defense to protect the battleships. As soon as the submarines broke through the defenses of the light cruisers on the perimeter, they would take on the heavy responsibility of protecting the battleships. If necessary, it even served as a meat shield for the battleship, blocking torpedoes for the battleship. After all, a destroyer costs only a few hundred thousand dollars, while a battleship costs tens of millions of dollars. It was well worth sacrificing a destroyer to protect a battleship!

Fifteen kilometers from the American fleet, the submarine forces of the naval base on the island of Santa Cruz were already parked at the surface of the sea. The U.S. military's anti-submarine network is very tight, and it is even more dangerous for the submarine force!

"Order the ships to prepare to infiltrate! Infiltrated the ranks of the US military at a speed of 5 knots and quietly crossed the anti-submarine net. After two hours, he ascended to periscope level and launched an attack on the nearest enemy ship. Evacuate immediately. Look for opportunities again! Colonel Li Long looked at the sea area in front of him that was illuminated by searchlights like daylight, and said with a somewhat ugly face! The tightness of the US military's anti-submarine network has exceeded his expectations. He also didn't know how many submarines would be able to return home safely after this assault!

In less than ten minutes, twelve submarines dived into the sea at a depth of 50 meters and sailed forward quietly. They will complete the two-hour voyage quietly before looking for an opportunity.

The two hours passed quickly. When the navigator reminded Colonel Li Long that the time was up, Colonel Li Long immediately ordered the submarine to rise to the periscope level and observe the situation on the sea.

Soon. A pitch-black iron pipe rose from the sea. The 221st boat was lucky, they had successfully penetrated the first anti-submarine net of the US army and entered the interior of the US fleet. The 221st boat was also in a good position, a huge battleship was not far in front of them, and it was sailing slowly at a speed of four knots!

"Good. That's this guy! Fish ready, launch! Colonel Li Long ordered excitedly!

The Shark-class submarines have two torpedo tubes and can fire two 533-mm heavy torpedoes at the same time. At this moment, 1,200 meters in front of the 211th boat, is the second ship of the 'Wyoming-class' battleship of the US Navy, the "Arkansas". The battleship "Arkansas" was carrying out a zigzag anti-submarine according to the regulations, not realizing that the crisis was approaching it!

"Bang bang!" Two muffled noises came to mind. Two heavy torpedoes rushed towards the battleship Arkansas at a speed of 30 knots. At the current rate. It only takes a hundred seconds for two heavy torpedoes to come into close contact with the battleship Arkansas. In order to increase the hit rate, after firing the first two torpedoes, the 221st boat was a minute later. Once again, two torpedoes were fired at the battleship 'Arkansas'!

After the torpedo was fired, the 221st boat quickly dived and put away the periscope. Get ready to escape from here, then look for another fighter!

But. It was at this time that a destroyer of the American fleet passed nearby. The searchlight also happened to shine here. The lookout above could clearly see a pitch-black tube diving.

"Black pipes? How can there be black pipes in the sea? Submarine! Submarines for the Chinese! The lookout did not hesitate to sound the alarm. Suddenly, all the destroyers and light cruisers were busy, and searchlights shone around, looking for Chinese submarines. And those slow battleships and heavy cruisers immediately began to accelerate!

"Torpedo! Two torpedoes on the port side! No, it's four torpedoes! Evade it now! "The soldiers on duty on the port side of the battleship 'Arkansas' also found water marks left by four torpedoes on the surface of the sea when they were sailing at high speed. The first two torpedoes were now less than 400 meters away from the battleship Arkansas, and the two torpedoes behind were 800 meters away.

The captain of the Arkansas immediately ordered the battleship to make an emergency turn. However, the speed of the battleship was very low now, and it began to accelerate, and it would take at least ten minutes to accelerate to more than ten knots. And the torpedoes launched by Chinese submarines will definitely not give them this chance!

"Boom! Rumble! "At 3:07 a.m., two loud bangs rang out on the port side of the battleship 'Arkansas', and the flames were blazing!

Two heavy torpedoes hit the battleship 'Arkansas' almost simultaneously, one hit the bow and the other exploded amidships! The huge impact force directly made the battleship "Arkansas" jump on the surface of the sea.

Hundreds of kilograms of high explosives in the heavy torpedo warhead destroyed the underwater protection of the battleship "Arkansas" and blew two large holes in the hull. The turbulent sea water poured into the battleship 'Arkansas'.

The captain of the battleship Arkansas asked the damage management personnel to find a way to save the battleship, but the damage management personnel could not do anything about it. Before the captain of the battleship Arkansas could react, two more heavy torpedoes struck. One of the torpedoes, due to an error in depth fixing, got through the belly of the battleship 'Arkansas'. However, another torpedo accurately hit the apostle of the battleship Arkansas again.

"Click!" The keel of the battleship Arkansas snapped in the explosion, causing the battleship to break in two in an instant. The raging sea water poured into the battleship, and in less than two minutes, the battleship, broken in two, sank into the sea, leaving a huge whirlpool on the surface of the sea!

The attack of the 221st boat was very smooth, but the attack of other submarines was not so smooth. Many submarines were spotted by U.S. Navy destroyers before they attacked. After discovering the submarine of the Chinese Navy, the US destroyer rushed over at high speed and launched a fierce shelling with rapid-fire guns! The shell of the submarine was very thin, and the roots could not withstand the bombardment of rapid-fire guns, so it had to abandon the operation and urgently dive. However, these US destroyers will not let go of the Chinese submarine, and after they drove to the area where the submarine was sinking, they began to drop depth charges in order to blow up the diving Chinese submarine!

"Boom! Rumble! Rumble! Violent explosions rose one after another on the surface of the sea, and columns of water rose on the surface of the sea. There were submarines that were blown up in the attack of American destroyers, and clumps of oil or rags and the like floated on the surface of the sea. Other submarines got out of the way.

On the bridge of the battleship 'Nevada', Admiral William Benson appeared on the bridge two minutes after the alarm sounded!

"How's it going?" Admiral William Benson asked. He had already expected the Chinese Navy's submarines to attack, but he didn't expect it to come so quickly!

"General, our destroyers and light cruisers are encircling the submarines of the Chinese. Battleships and heavy cruisers are accelerating! The officer on duty reported.

"How's the loss?" Admiral William Benson asked.

"The Arkansas was sunk. There were no losses on the other ships! The officer on duty replied.

"Hmmm! Let the destroyers and light cruisers intensify the encirclement and suppression, and blow up all the Chinese water rats to the bottom of the sea! Admiral William Benson ordered with a cold face. A battleship was sunk, which made him very painful!

Fierce fighting on the sea continued, and many submarine attacks were unsuccessful. After being discovered by the US warships, some submarines hastily fired torpedoes and then made an emergency dive. Other submarines dived without even firing a torpedo.

At 3:21 a.m., there was another loud bang on the sea. The 226th boat of the Chinese Navy fired a torpedo at a distance of 1,500 meters from the US Navy's battleship 'Arizona'. It's just that at this moment, the speed of the battleship 'Arizona' has increased to 8 knots. In evasion, he managed to dodge one torpedo, but was hit by another torpedo in the stern. Although this blow did not kill the battleship Arizona, it also caused it a heavy loss. It's just that after the 226th boat fired another torpedo, it was pierced through the shell by the destroyer of the US Navy that arrived in time, and after the turbulent sea water poured into it, the submarine sank into the sea and never floated again!

It took two hours for the U.S. military to stop encircling and suppressing the Chinese submarine. At this moment, they are already twenty kilometers away from the sea area where they were raided, and they have long been out of the range of Chinese submarines. However, during this raid, one battleship of the American fleet was sunk and the other was heavily damaged, which caused heavy losses to the American fleet.

The losses of China's submarine forces were also quite large, and only three of the twelve submarines eventually returned to Port Ayora. Even the 221st boat of the commander, Colonel Li Long, was sunk in battle!

After receiving the battle report, Rear Admiral Li Hai, commander of the naval base, fell silent. Subsequently, he sent a telegram to his family, the content of which was very simple, just a few words: My brother has been loyal to the country!
