A change in the strength of the current in a conductor produces radio waves. Using this phenomenon, information can be loaded on top of radio waves by modulation. When the radio wave travels through space to the receiver, the electromagnetic field caused by the radio wave will generate an electric current in the conductor. The purpose of information transmission is achieved by extracting the information from the current change through demodulation. This is how radio works. However, because it is a natural propagation, unlike wired transmission, a shielding structure can be added to the outside of the line, so the electromagnetic waves naturally generated by the earth will interfere with the radio waves, and in severe cases, it is even impossible to communicate.

Popov was well aware of this, and his research found that many places seemed to have naturally occurring electromagnetic waves, but they were limited to land. But at sea, the natural wave signal is much weaker. And along the way, the entire sea voyage did not appear to be serious enough to be unable to communicate. Strangely, since the proximity to Madagascar, there have been serious disturbances from time to time, and this phenomenon has gradually increased over time. Popov glanced back at the dimming lights of Nosibe, shook his head, and continued to fiddle with his wireless telegraph.

The wooden radio transmitter was rudimentary and crude, but in Popov's eyes it was a perfect work, because it did not need a telephone line or a transponder station to reach a partner thousands of kilometers away. It's just that radio research was funded by the Russian Navy Minister of the Navy, Grand Duke Aleksandrovich, with naval funds, so the results of the research were exclusive to the Russian Navy. The reason why Russia was able to make up its mind to go on an expedition this time was precisely because of the wireless telegraph that could communicate with each other over a long distance, and the entire Russian fleet sailing thousands of miles did not lose even a single gunboat. This is a recognition of his research. And after the war, Russia will announce the results of his research. He will be famous all over the world.

Popov replaced the wireless telegraph with an electronic tube, which was a very delicate thing. A collision or even too vigorous shaking can cause the tube to malfunction. The most important thing is that the life of this kind of tube that has just been studied is very unstable. After leaving Russia, it broke down once on the way, but after replacing it, it was used until it was close to Madagascar, and then the situation changed. The chances of tube damage are getting higher and higher, sometimes so high that you have to replace several a day, which is not normal. Popov wasn't unaware of other possibilities, but radio was still Russia's top secret, and he knew that scientists from many countries had already started working on it, but he didn't know of any country that had done so. However, it seems to be stable again before docking. It had been days since he had been told that he needed to go to Hugh.

The tubes were replaced, and Popov was turned on for testing. The tick-tick telegram sound is crisp and rhythmic, and everything seems to be fine. But Popov did not leave immediately, because the soldiers on duty before he came in told him that this thing would always ring for a while, and that it would stop after a while, and then it would ring again for a while, as long as he was left alone. And the reason why I called him over this time was because this thing had been ringing for more than an hour, and these soldiers on duty couldn't stand it and called him.

This puzzled Popov. It should be said that even natural disturbances should be continuous, and even if there is a change in intensity, it should be a gradual signal, and there can be no sudden change. Popov decided to see.

It was already summer in the southern hemisphere at this time, but because the cabins and decks were full of coal. Even the portholes can't be opened, because as soon as they are opened, they are blown up by the wind, which can cause a short circuit in the fragile electronic components. So as long as you stay here for a while, you will sweat. Only ten minutes later, Popov, unable to stand the heat, walked out. At least it's still windy outside. But as soon as Popov stepped out of the hatch, there was a sizzling sound from the wireless telegraph. This is the sound that is produced when it is interfered with by other wireless waves.

"Turn it off, I won't need this thing right now anyway." The soldier on duty could not stand such a noise and had to go into the cabin. Of course, Popov stepped forward to stop him, because he wanted to see for himself how he would stop automatically. It's just that Popov, as a scientist, was the soldier's opponent, and the soldier pushed him away and walked in. He couldn't stand hearing this noise every day, and he thought he would be crazy to listen to it any longer. But the soldier reached out to the wireless telegraph, and the noise stopped empty. The soldier looked back at Popov blankly and said, "I haven't touched it yet." ”

Just when everyone didn't know what was happening, the wireless telegraph that had just stopped suddenly made another sizzling noise, but this time it was very loud and very harsh.

"Turn it off, turn it off." Popov screamed and rushed into the hatch, by which time the soldiers in front had turned off the wireless telegraph. When Popov checked again and found no other problems, he suddenly reacted, and the natural signal did not appear out of thin air and the message was lost, nor did it suddenly increase or decrease, only the controlled signal could do so. If this is the case, it means that there is a higher-power radio transmitter in the vicinity that is controlled by a human. This means that the other side has invented a jamming device that can restrain the radio, so they must also have a wireless telegraph, and they have also transported this jamming device nearby. Popov believed that the size of this charge was not small, and since it could move with their fleet, it meant that the jamming equipment was mounted on board. If this equipment is owned by the Chinese, and then think of the four strange warships that suddenly appeared in the rear of the fleet a few days ago, then the calm of these days is actually that the Chinese are calling other fleets, and perhaps this sudden loud noise is a signal that the Chinese are ready to attack.

The Commander must be notified immediately. Popov's thought had just risen before he was choked by himself. Because if other European countries have such inventions, they will definitely be known to the world because of patent applications, and that backward China already has jamming equipment, which sounds too absurd. Even if he could theoretically create jamming devices, but limited by tube technology, such a large power is not realistic! After thinking about it for a long time, Popov decided not to tell the secret for the time being, but there was always a feeling of impending disaster in his heart, so he left the ship and went ashore, and this feeling was much better.

He felt right. He had barely landed when a large red dot suddenly appeared on the sea. The loud explosion startled the already sleeping Russian Far East Fleet, and the subsequent roaring sound of breaking the air and explosions threw the world's Third Fleet into chaos.

"Which bastard is doing the trick again?" Awakened by the explosion, Roger Stevensky had not yet had time to put on his coat. I was shocked by the explosion outside the window. One shell after another exploded on the warship, and the flames of the dense explosion illuminated the entire bay. Shouts came from all sides desolately. After tens of thousands of nautical miles, the Russian fleet was exhausted, and when it finally found a place to relax, it immediately lost its last vigilance, and the sudden shelling overwhelmed everyone. Roger Stevensky again played the role of commander of the gendarmerie in this flustered scene.

"Go back to your post and use your artillery to return fire on the enemy." Rogerstinsky's roar soon reached the ships, and all the soldiers on the ships quickly took up their posts.

Ocean voyages are no different from others, and it is easy to have a nervous breakdown in the face of monotonous sea and air colors for a long time. This situation has also been encountered by the Chinese Navy, but the direction of the Chinese Navy's handling is focused on soothing. In the free time when there are no combat missions, except for duty posts, other personnel can move freely on the deck, and some activities such as fishing, singing, and storytelling are organized on the ship from time to time. Treat yourself with fresh fruits and vegetables as a reward to soothe your spirit. But Rogerst Winsky's method was harsh punishment, and the soldiers in this high-pressure state did not care about the external environment. So when the fleet was attacked, the chaotic scene quickly returned to order, because everyone was afraid of Roger Stevensky's fist.

However, when the fleet began to turn the cannons, the fleet in the distance suddenly ceased fire, and for a while all the gun positions were silenced and waited for Commander Luo's order. In this silence, what Rogerst Wensky heard was the sound of the propellers of the opposing fleet fading into the distance.

"Everyone is on standby, ready to fight at any time." After giving the order, Roger Stevensky went back to sleep in the cabin. He did not think that the enemy would appear again, and all the naval guns were already ready, and even if the enemy appeared, he would be able to quickly counterattack. After dawn, Roger Stevensky's adjutant woke him up. What he saw was a fleet in disarray.

Zhou Haicheng was holding a bun in his mouth at the moment to watch the communications non-commissioned officer overhaul the radio. Last night, the Yellow Sparrow emitted interference radio waves at high power in order to cause a large amount of noise on the radio of the Russian fleet. Because the light patrol formation will still produce noise even at low speed, and this sound will become obvious in this quiet night. But strangely. Just as the Yellow Sparrow emitted a high-power interference wave, one of the radios on the Dinghai suddenly smoked and caught fire. At that time, the fire was extinguished in time and no other damage was caused, because it was a night voyage and the lights could not be turned on. So the overhaul waited until dawn the next day. It's just that the technical non-commissioned officer who is overhauling reports a strange problem.

"It's not wrong that the tube was burned, but this burnout seems to be caused by an overload of current. And when the interference wave was launched last night, all the stations were not working, so it stands to reason that there shouldn't be such a phenomenon, right? The technical non-commissioned officer was puzzled, but he decided to fix it first.

"Don't fix it, just send it back as it is. Maybe those madmen from the Chinese Academy of Sciences will know what to do. Zhou Haicheng stopped the non-commissioned officer from repairing the radio station.

"But captain, this way we have one less radio, which is not in accordance with the regulations of the voyage." The non-commissioned officer was right, the Chinese Navy's regulations on long-distance voyages clearly stipulate that all equipment on ships on long-distance voyages must not be returned to port in a damaged condition unless it cannot be repaired.

"I just thought that if it was the interference wave that caused the radio station to burn up, maybe it would be the new weapon. Of course, it may not be for this reason, so it is better to take it back and let the scientists study it. As the emperor said: maybe when you study the length of a pig's tail, you will find that a cow has four stomachs. I can't figure it out as a soldier, but isn't science so nervous? It doesn't matter, our radio station is enough for communication requirements, and one less does not affect anything. Besides, this is my order, and it has nothing to do with you. ”

Perhaps for these scientists, when studying the length of the pig's tail, they will find that the cow has four stomachs is a miraculous thing, but most officers and soldiers think that the pig's tail and the cow have several stomachs with wool. Including the young Zhou Haicheng also thinks so. However, the captain said that it would not be repaired for the time being, and the technical non-commissioned officer would naturally do the same. He carefully wrapped up the radio station and put it away, waiting for it to be handed over to the Chinese Academy of Sciences after returning to China.

Zhou Haicheng, who had finished breakfast, went to sleep. The four Dinghai-class light patrols floated quietly on the sea about 100 nautical miles northwest of Nosiebe, and there were only a small number of officers on duty on the entire ship at this time. Because the action is at night, you need to rest during the day to replenish your energy. However. Nosibe's Russian sailors were not so lucky. After the attack last night, I was on guard in fear for a whole night, and during the day I had to repair the ship. Their spirits are on the verge of collapse.

"Don't sleep tonight, all stay by the cannon in case the enemy strikes again." Rogerst Winsky thought well, and the soldiers all arrived at their posts. There was only a small accident, and when the enemy attacked, almost all the soldiers fell asleep.

The time when the Chinese launched the attack was well chosen, and four o'clock in the morning was the time when people were most tired. The Russian soldiers, who had not slept all night last night and were tired all day, couldn't bear it after the first half of the night, and the soldiers who had supposed to rest in batches all fell asleep, and the explosion of enemy shells on the warship did not wake up all the soldiers.

The level of the Russian Navy is very poor, but that's only for the majority. Among the tens of thousands of naval soldiers, there will always be a few elite figures. These people reacted quickly, and after a simple judgment based on the fire of the enemy ship's guns, they directed the main guns to start a counterattack. It was just that they were very puzzled by the fact that from the point of view of the explosion effect and destructive ability of hitting their own ship, it should be a small and medium-caliber shell of no more than 200 mm, but no matter how they operated the main gun to return fire, they did not find any signs of hitting the opponent, and judging from the fire of the enemy ship's gun, the enemy ship did not react to their return fire, because it seemed that the sparks from the enemy ship's gun were still neat and moving at a stable speed. What's even more puzzling is that it seems that his main artillery can't reach the other party's fleet. You must know that the Duke Kensuvorov-class battleship in the Russian fleet is one of the most advanced battleships in the world today, and its 305 mm guns have a range of 14,000 meters. No 200-mm shells have hit far? It's incredible.

There is nothing unthinkable, the Chinese Navy, which has long been familiar with every ship of the Russian expeditionary fleet, has already taken countermeasures. The artillery bombardment was launched at a distance of 15,000 kilometers from the main position of the Russian battleships, so he did not worry about the counterattack of the Russians, as long as their capital ships did not chase them out of the harbor. The Dinghai 4 ships, which have been replaced with the latest 52L/152mm naval guns, have a maximum firing range of up to 20,000 meters.

Zhou Haicheng is also very clear. In fact, the effective firing range of the four ships in Dinghai is only 12,000 kilometers, and one of the reasons is that the barrels currently developed by China cannot reach the performance of the same type of British naval guns in terms of performance. And the most important reason is that the 152-mm shells are too light. But the range is more than 12,000 kilometers. The kinetic energy of the projectile in flight is insufficient, and it is easy to be disturbed by atmospheric flows, resulting in severe scattering. The purpose of this artillery bombardment of targets at a distance of 15,000 meters was not to destroy many enemy ships, but to exhaust the Russian expeditionary fleet. Make it impossible for them to recuperate, and then harass them along the way. Exhausted the Russians alive. In the end, it gave the first blow in the South China Sea and completely knocked out the Russian expeditionary fleet.

Exploiting one's strengths and forcing one's weaknesses to attack the enemy's weaknesses with one's own strengths is the right way in the art of war. Since the greatest advantage of the Chinese Navy over the Russian expeditionary fleet is speed and range, why not take advantage of it? Relying on this idea as a guide, the Chinese Navy has sent the fastest cruiser in the Chinese Navy to the Indian Ocean. Of course, it was impossible to rely on 152-mm naval guns to try to inflict any damage on the battleship, so the light patrol assault group aimed at the destroyers and cruisers on the outskirts of the port, and the hit rate was not included in the shelling effect, but the Russians artificially increased the hit rate of the Chinese.

The Baltic Fleet led by Roger Steven's departure consisted of forty ships, large and small, and by the time the Black Sea Fleet arrived, the total number of ships reorganized by the Black Sea Fleet was fifty. Battleships, light and heavy cruisers, destroyers, gunboats, work ships, support ships, and transport ships, large and small, 50 ships of all kinds docked in the small port of Nosy Bey and the side of the ship, so dense docking made it difficult for the Chinese artillery bombardment to miss. Moreover, Roger Stwinst also docked the battleship at the innermost side, and it was impossible to pursue Ben quickly, while those small ships were not the opponent of Ben's Dinghai-class light cruisers. Moreover, there are naval special combat personnel on the shore monitoring the sea surface, so there is a Dinghai-class light patrol formation that can easily carry out artillery bombardment missions, as if it is a training exercise, and there is no pressure on Ben.

Although the task was very easy, Zhou Haicheng understood that in fact, the Dinghai-level light patrol was already old. After all, this must have been designed ten years ago. In the past ten years, countless new technologies have been born, and countless old ones have been discarded. The First Battle off the coast of Lushun showed the world the role and ability of light patrol. As a result, countries around the world began to imitate one after another, but China, as the first design country, stopped continuing to build light cruisers and instead built heavy cruisers and battleships. Ordinary naval officers did not understand the intentions of the imperial court. They all think that the Dinghai-class light patrol is an excellent warship that can respond quickly for a country with a sea frontier of thousands of miles, but for some reason, the imperial court only built four ships and then had no construction plan.

However, Colonel Commander Zhou Haicheng, who had been promoted to the command of the assault formation, understood that the Dinghai class must only be a light patrol, and its role was only to use speed to carry out assault or sabotage attacks, and it could not be used as the main warship, and the main task of the imperial court in these ten years was to defend the Russian expedition, which required the main defense force such as heavy cruisers and battleships. Only when this Russian expedition was completely defeated would the imperial court change its naval strategy from defense to offense, and then the light patrol would play its role. And Zhou Cheng still knows. The design of the new Light Patrol has been completed, and as long as this battle is won, the new Light Patrol will immediately lay the keel. And then the Chinese navy will rush into the Indian Ocean, as it did this time, and it will rush to the other side of the Pacific, and it will rush into the Mediterranean and into the Atlantic......

Zhou Haicheng put down the binoculars, raised his head and looked at his watch: "Order all ships to stop shelling." Follow the flagship to evacuate the battlefield. ”

The half-hour-long shelling was over, and the Russian sailors, who had just recovered from the fear of death, began to pick up the pieces again under the roar of Roger Winster. Another night passed on such an attack. Although both nights fought back against enemy attacks. But nothing came of it, and the momentum of the soldiers had fallen to the bottom. Many soldiers are saying that the Chinese navy has experienced more damage than the British navy, and that they have been able to defeat the world's third-strongest fleet with only four warships. So much so that after only one night, rumors began to flow out of the fleet about their expeditions. In fact, it was the tsar who sent them to their deaths, just because there were many redists in the fleet. And such rhetoric has already affected the Black Sea Fleet, whose morale is still good.

Roger Sterwinster began to use harsher punishments to suppress rumors in the fleet, but he had to face the reality that the world's third-strongest fleet had been sunk by four Chinese warships, and one destroyer had been seriously damaged. There was also a light cruiser that had lost its combat effectiveness, and many heavy cruisers and battleships were shot. And the enemy is still unscathed.

"I looked at the records of the attacks for these three days. Except for the first day, when the shelling of Chinese warships did not have a definite target, the other two days the Chinese warships concentrated all the shelling on the small branches on the outside. If the Chinese Navy is allowed to destroy these small ships. In that way, even if the capital ship could reach the Far East intact, it would not be able to withstand the torpedoes released by the faster destroyers of the Chinese. I think it's necessary to adjust the formation, put the faster Black Sea Fleet warships on the outside, and if the Chinese warships carry out another night attack, at least we can fight back a little. "Rear Admiral Folkshan, who led the Black Sea Fleet and was also deputy commander of the new Russian Pacific Fleet, made a proposal to Roger Stevenster. Because if this continues, the Russian fleet, once it loses all its small ships, will not be able to compete with the more agile Chinese navy. Because it was only China that fought to sacrifice destroyers, it would be able to sink all the Russian fleet with torpedoes sooner or later.

Roger St. Winster agreed with Fork Hill and spent the whole day adjusting his deployment. Roger Stewinst did not understand the tactics of steel battleship warfare, but he must have experienced the era of sail warships, and the entire harbor still left a passage sufficient for battleships to travel when arranging to dock battleships. So Roger Sterwin once again demonstrated the strength of the commander of the gendarmerie, and in just one day, all ten ships of the former Black Sea Fleet moved to the outside, and all the ships of the original Baltic fleet moved to the inside, and everything was in order. The Russian fleet is ready for everything, and the Chinese fleet is not coming! This Roger Stevenster off.

On the morning of the fifth day, Chinese warships appeared at sea level. The four 10,000-ton cruisers lined up slowly, and the naval flag was hung on the highest part of the warship, and on the navy flag on the blue background, a golden dragon was rushing out of the sea, and the dragon's mouth was about to roar. The bow of the ship's knapsack triple gun with six barrels goes directly to the port of Nosibbe.

"Uh-" The alarm sounded throughout the port, and the soldiers entered the battle positions, but no one was in a hurry, and the Chinese were still far away.

"This is the Chinese warship." All the Russian sailors gathered on the side or at the window to look at the neatness and seriousness of the formation, and then to look at themselves. Countless Russian sailors sighed: This time they really went to the Far East to die.

The four Dinghai-class light cruisers approached Nosy Bay at a low speed of 12 knots, then began to turn 20,000 meters away, and finally formed a battle line at 15,000 kilometers, after which the turrets began to turn and the barrels were raised.

"Boom!" After a loud bang, 48 shells flew out of the Chinese fleet, and flew towards the Russian fleet with the sound of breaking through the sky. They flew past the highest point and fell almost vertically when they ran out of power. "Boom-" A series of dense explosions rang out on the Russian ships, but due to the adjustment of formation, only a few hits were made, and the battleships and heavy cruisers at the forefront were not afraid of this kind of shelling.

"Sortie." Rear Admiral Falk Hill gave the order to attack, and as early as the appearance of the Chinese Navy, he had already ordered the fleet to begin pressurizing and standby. When everything was ready, the huge propeller stirred the sea water and propelled the giant ship to move.

"Keep your distance, reduce the intensity of shelling to once per minute." Zhou Haicheng saw the Russian attack, so he ordered to turn to the open sea.

Rear Admiral Falk Hill chased him out of the harbor, but was so fast that he had to return after two hours of pursuit. Over the next three days, such sorties and pursuits continued to be staged.

"The fact that the world's third-strongest fleet was crushed by four old Chinese cruisers and that there was nothing it could do made the entire Russian Empire a joke in the world!" Roger Sterwinster summoned the generals to a meeting, at which he read out His Majesty's decree. Then the people will ask for a solution: "If we continue like this, we will be beheaded by His Majesty without going to the Far East." In addition, we received information from the British that there are only these four Chinese warships in the entire Indian Ocean. ”

"Although we are slow, we are numerous, and we have figured out the route of the Chinese in the past few days. There is no need to return to port after the pursuit tomorrow, and the Black Sea Fleet will ambush the open sea with other fast warships. As long as the Chinese dare to come in again, we will communicate with the radio and surround the Chinese and annihilate them all. ”

An agreement was quickly reached at the meeting, the tasks were assigned to the ships, and the morale, which had been low for a long time, finally began to pick up. The attack and defense on the eighth day were exactly the same as the first four days, and the Russian fleet continued to pursue for two hours without success, but they did not return to port.

On the ninth day, still at that time and in that direction, the Chinese fleet came by the same course at the same speed and angle. Roger Stevenster looked at the unhurried Chinese fleet and laughed wickedly: "This time you have no return." Offensive - "The Baltic Fleet, which is ready to attack, starts at the same time. (To be continued......)
