Although the waterway on the north bank of the Yangtze River was laid with mines, it still left a hidden passage, and it was not difficult for Lin Han's ship Sephiroth to safely pass through Guò at night.

The Sephiroth, a non-professional torpedo boat converted from a speedboat, is currently the "strongest" torpedo boat of the Red Army. In fact, after Lin Han drove him from Germany to China, he did not plan to sail back to Germany for such an exaggerated round the world tour, and the ship would remain in the Red Navy for a long time to come. In Germany, Lin Han has prepared a new spirit ship for himself, which can be transferred by extracting the core and putting it into the new ship.

After the destruction of the Nationalist Government in Nanjing, most of the naval trophies received by the Red Army from the artillery party were river gunboats, and the largest trophies were the Pinghai and Ninghai.

In Jiangyin, the Ninghai, which had been heavily damaged by the Red Army's frogman troops, had been plugged up today, pumped up and floated, and according to the plan, after the power system was repaired, the ship would sail to the Hankou shipyard for repairs. After the expansion, the current Hankou shipyard is now able to carry out repairs on ships of 3,000 tons.

In front of the ship, the ship's guns are being dismantled in Jiangyin, and according to the plan, the ship's main guns will be moved to the Shanghai area in the coming days to serve as defense batteries along the river.

At the end of the Battle of Shanghai, the Red Army captured all ten torpedo boats of the Nationalist Government in Nanjing, but most of these torpedo boats were more than 30 years old and could not even be used as river gunboats. The four Star torpedo boats were also urgently ordered by the Qing court during the First Sino-Japanese War to obtain ships to support the war, but they were unable to return to China in time to participate in the war because of the neutrality of various countries. When they were seized, they were all parked at the Xiaguan Wharf in Nanjing. These "old lady" class warships in the First Sino-Japanese period have been lying there for nearly a year because of the scrapping of the power system, and they are severely corroded, and they even have to be considered twice for transportation on the Yangtze River after repair, perhaps it is the best choice to disassemble and return to the furnace directly.

The other two "column" and "Zhang" characters were built in 1895 by the German Shuoxiao shipyard, and these two forty-year-old "grandfathers" had long been hired by the Red Army to run and transport in the Yangtze River, and the power system was barely usable.

As for the four lake-class torpedo boats left over from the Zhang Zhidong era. These four were trophies of the Red Army in Shanghai. Their ships are a little younger. Completed in 1907, 97 tons of displacement tonnage, coal-fired vapor power, maximum speed 23. In the melee of more than ten years, all ships are good at fighting and killing in the upper and lower reaches of the Yangtze River. There was a lot of damage to the hull. The main engine was in disrepair, and its speed had dropped to only about 20 knots, so it was equally useful to ask them to go to sea to fight. The same. The German black-headed torpedoes, imported more than 20 years ago, installed on the ship, are old and have long been scrapped.

After inspecting these ships, the German experts also shook their heads vigorously, and the advice they gave them was to use them as patrol boats.

Compared with these old lady and grandfather-class torpedo boats, the Sephiroth can run at a high speed of 31 knots even when the ship's turbodiesel engine is turned on when it is fully loaded—and this 31 knots of high speed is due to the fact that he sacrificed a lot of space to install diesel in order to sail across the ocean. After the Sephiroth was re-entered the Jiangnan shipyard, the shipyard workers took matters into their hands by removing the redundant buildings and facilities on the upper part of the ship, pumping out unnecessary excess fuel and restoring the ship to its true appearance when it was renovated in Germany.

In Germany, when the Sephiroth underwent its last major overhaul, the hull superstructure was redesigned to the standards of a torpedo boat. Most of the superstructure was a "camouflage" attached to the hull with exposed bolts, which was extremely convenient when dismantling - this was prepared to facilitate the rapid transformation into a torpedo boat in China. Skilled workers at the Jiangnan Shipyard worked together to dismantle all the redundant facilities in the upper part in less than an hour.

The large outboard oil tanks, which were higher than the deck and were prepared for transoceanic sailing, were all dismantled in the process, and some of the small oil tanks in the boat, after pumping out the fuel and installing the accessories that had been prepared for a long time, immediately resumed the function of the original design ammunition depot.

On the roof of the cockpit of the Sephiroth, a 30 mm caliber rifled gun was installed, which, like the Galin anti-aircraft gun, was a new product under development, and only five were built in Germany for testing, three of which were sent to China, and were installed on the Ruijin, Pinghai and Sephiroth respectively. (Note: Historically, the rifled guns were not equipped with the German army until around 1944).

The aft deck of the boat was also specially reinforced during the German remodeling, and it was perfectly possible to install a 76 mm high-level dual-purpose gun, but for the sake of tonight's operation, no weapons were installed here, and the weight saved was turned into armor to protect the rear of the cockpit.

After this overhaul, the Sephiroth was greatly lightened, and the weight of the ship was only 360 tons under standard load, and the maximum speed, according to the experience of testing in Germany, was estimated to be between 33 and 34 knots.

Had it not been for the fact that the Sephiroth had been designed for yachting purposes rather than torpedo boats, the speed of the boat would have gone up to a new level, even if it had been overhauled and a lot of space had been wasted in order to provide better accommodation for the crew and sailors.

Compared with the 10 "cultural relics" torpedo boats of the "grandfather" or "old grandfather" level of the Nanjing government, the current Sephiroth is simply a "tall" "noble" with an outrageous fashion value. When he was sent to the Jiangnan Shipyard for emergency renovation, the officers and men of the Red Army who were about to receive the ship stared at him with stars in their eyes and looked like they wanted to swallow it.

Some of the naval personnel who received torpedo boats were sailors trained by the Red Army or instructors of Lin Hantong Guò Su and Germany in recent years, and a small part were temporarily "volunteers" sent by the German Navy.

For the navy, which suffered from the harsh living conditions of torpedo boats, the living environment of the "Sephiroth" can be called a "palace on the water". Even the sailor's cabin, which was preserved by the demolition of the superstructure, was in much better living conditions than the captain's cabin of the "Pinghai".

Look at the amazed look of those naval soldiers who have never been abroad. Lin Han muttered in his heart: "If you see the luxurious furniture in the superstructure that has just been demolished, you must shout that this is the evil of the corrupt capitalist world." ”

On the way back to China from Japan, the Sephiroth could not abandon the "miscellaneous" that was "full of decadent capitalism", such as Lin Han's own "multi-functional sports bed" and "shaker" equipment for "very loving activities".

The Sephiroth joined the Red Navy and was officially renamed Nanchang.

As for the new 30-mm rifled gun installed on the Nanchang, the reason why it was sent to China for testing was the rifled gun and not the Gatling gun, because he was a pit dug by Hannah for the Soviets.

Compared to the Gatling gun, the rifled gun is lighter, with a smaller projectile dispersion area and a higher fire density. And there is no longitudinal movement of the automaton with a large mass. The mechanical shock generated when firing is also minimal.

Although the advantages are big, the disadvantages are not small, the biggest disadvantage is that the gun has extremely high requirements for the accuracy of the processing process, and requires high-precision machine tool lathes and excellent skilled workers. Even after World War II. When the Soviets were faced with the choice of a rifled gun and a Gatling rotary cannon. In the end, the latter with low processing and manufacturing difficulty was chosen.

Hannah also did not plan to equip the German army with a rebellious gun, a weapon that is difficult to mass-produce with current technology. This was developed purely for the purpose of technical stockpiling. And in China, the trial was to dig a hole for the USSR.

Lin Han was a penetrator, and this identity was already known to the Soviet Union.

What is the biggest advantage of the traverser?

Know where the future is going. and knowing the right direction for future technological development.

History will change because of the interference of the time-travelers, but the correct direction of scientific and technological development is not something that the time-travelers can change.

Lin Han and Hannah's analysis of Stalin's behavior and train of thought is certain, that is, when he climbs the tree of science and technology, he must instinctively ask the Soviet Union to "keep up" with Germany's pace, and whatever road Germany takes, the Soviet Union must also take.

This is human nature, because in Stalin's view, Hitler (Hannah's mother and daughter), who was close to Lin Han, must have known the correct answer under the influence of Lin Han.

In the next few decades, the rifled gun may be suitable for Germany, a country that is good at precision machining, but it is definitely not in line with the national conditions of the Soviet Union.

Hannah believed that in the air battle between China and Britain and Japan, the rifled gun would have an excellent performance, and that Stalin would definitely seek this technology, and then she would follow the trend and sell all the design drawings and samples of the gun to the Soviets.

Even with the current technology of Germany, in order to manufacture these five rifled guns, it took a lot of effort, completely relying on a group of high-level technicians to process the parts by hand, and then she herself relied on her ability to make subtle adjustments before processing them.

If Stalin ignored reality and forcibly tried to light the "rotor cannon" in the thirties and forties, he would only waste manpower and material resources and fall into the "trap" that Lin Han and Hannah dug for him.

At seven o'clock in the afternoon, when night fell, the Nanchang with 30 sailors on board sailed out of the Jiangnan Shipyard for the renovated sea trial. As the newly received sailors were not yet familiar with the ship, the task of operating the ship was carried out by German sailors brought in by Linhan – whose real identities were also from the German Navy.

On the 15th, the weather in Shanghai was very bad, and there were still showers, and the JU52 transport planes sent out to find the Third Fleet encountered heavy rain on their return, and although they were forced to land at Hongqiao Airport, one of them had a little landing accident when landing, and when landing, they rushed out of the runway, and the nose of the plane almost touched the ground and almost took the big top, and the crew on board only suffered some minor injuries.

The two Junkers transport planes that returned to Hongqiao Airport not only transmitted back intelligence from the Third Fleet, but also brought back photos taken by them.

On the other hand, the divers led by Lin Han and Li Huamei salvaged from many sunken Japanese warships, and the intelligence officers of the Red Army also made heavy discoveries.

On board the Seta, a briefcase was retrieved from one of the crew's personnel, which was later handed over to the Red Army's intelligence services, in which they found all the telegrams of the previous days between the Nagaflota and the Japanese and Taiwanese garrisons.

As the flagship of the Japanese River Fleet, the Shita was not only targeted by the six 140mm guns on the Hirakai. Dozens of 105 mm French cannon howitzers were fired indirectly, countless bullets fell on the ship, and the custodian of the telegram was killed in the shelling.

This was a very precious bonus, and these days, the Red Army had been listening to Japanese radio communications, and with these telegrams as a reference, it became very easy to decipher the Japanese codes in the short term. What's more, pass guò these telegrams. The Red Army got the exact plan of Japan's next move.

One of the most precious pieces of information. It was the telegram that was wet by the river that the Red Army learned that the Japanese had dispatched a total of 14 warships of the Third Fleet from Taiwan to Shanghai for "armed intervention," the scale, time, and destination of the sortie. And the number of troops dispatched is clearly written.

And after the reconnaissance aircraft confirmed the location of the Third Fleet. The authenticity of this information was confirmed. The only problem is. The intelligence stated a fleet of thirteen warships plus two passenger ships and two freighters, for a total of seventeen ships. But this distinction was verified in another telegram.

The telegram made it clear that the two destroyers who had not appeared in front of the reconnaissance planes were escorting the two slower passenger ships and the two freighters, and that they had left Keelung in nearly seven hours less than the former.

These two telegrams excited all the senior leaders of China, the Soviet Union, and Germany who were concerned about the war.

In other words, the Japanese troop carriers that were heading for Shanghai were now escorted by only two destroyers, and their defense forces were now extremely vulnerable.

Although the intelligence did not list the detailed route of the troop carriers, from their correspondence with the river fleet stationed in China, the Red Army was informed that they expected to arrive at the mouth of the Yangtze River at about 8 to 9 o'clock tomorrow morning.

With the time of their departure and the time of their final arrival, it is easy to deduce the route of the troop carrier by taking a ruler and measuring it on the naval map, and with a little calculation.

Even Lin Shuai, who was born in the army, couldn't help but laugh softly after seeing the stack of telegrams.

"It's a great gift to your door!"

While the Nanchang was still preparing and testing for a night raid by a lightning strike, military observers from the Soviet Union and Germany had already begun to help the Red Army plan on the drawings a timetable for Japan to different locations off the coast of Shanghai, preparing to give the Japanese another "surprise" tomorrow with the help of the air force.

However, on June 15, the weather in this part of Shanghai was extremely bad, the sky was gray and heavy all the time, and the rain was incessant, which not only brought great trouble to the Red Army, which was doing urban sanitation and propaganda work, but also prevented the Air Force from dispatching. However, Hangzhou, which is far away from Shanghai, has signs of improving weather, and by 5 o'clock in the afternoon, it has turned into a clear sky and white clouds.

At 5 p.m. on 15 June, the Third Fleet finally reached the mouth of the Yangtze River.

In the past, ships came and went, and the lively waterway of the Yangtze River was so deserted that not a single boat could be seen at this time. It was a rainy day, so it was dark at 5 p.m.

Hyaktake Gengo stood at the bow of the Izumo, and in the distance, the land of China seemed to be just a thin black line.

The annihilation of the combined British and Japanese fleets and the loss of the concession had the greatest impact on him was the loss of key sources of intelligence. The Japanese had been operating in Shanghai for many years, and there were countless hidden spies, but after the Red Army entered and took Shanghai, the first thing they did was to suppress the counter-revolutionary, black (crab) society and traitors. Although it took only one day for them to completely take it, they got the information provided by the former Central Commander and the former Military Commander, and they directly arrested people according to the names given on the list.

The Nanjing Nationalist Government has always been soft-hearted to the outside world, leading traitors and traitors to run rampant in the ruling areas, and in many cases even to the point of semi-openness. Over the past few years, the two major spy organizations of the Central Command and Military Command have more or less collected the "black materials" of many people in Shanghai, plus Wang Yaqiao and the Mocking Wind Organization. When the Red Army entered Shanghai, it grasped the anti-espionage, anti-traitor, and anti-special aspects extremely tightly, and under the red pressure, as well as the corpses of countless criminal and evil traitors in front of the Longhua Garrison Command, it really alerted many traitors who had not yet been caught, and they had to restrain themselves in fear.

Without the eyes of the concession, the third ship, which has come to the waters outside Shanghai, is now blind to the specific situation in Shanghai.

"What is the specific distribution of the Red Army's forces on the Yangtze River?"

"What is the distribution of anti-aircraft artillery along the riverbank?"

"Has the Yangtze River been completely blocked by mines? Are the waterways safe? ”

He didn't have any of the information he had to know. All of the Japanese plans of action for the invasion of Shanghai were based on the premise of having the support of the defenders of the concession and completely controlling the waterway of the Yangtze River. When departing from Taiwan, the Third Fleet did not think of "demining" at all, and there was also a lack of minesweepers among the ships accompanying it.

Off the Yangtze River, he telegraphed to American warships in the Public Concession, and with the help of the Americans, he got in touch with the British consul and got a general idea of the Battle of the Concession. After the contact was completed, Hyakutake Gengo did not say a word, and immediately ordered the entire fleet to retreat forty nautical miles to wait for the arrival of the home fleet and the Taiwanese transport fleet.

After learning about the combat effectiveness of the Red Army and the artillery density displayed in the Battle of the Concession, no matter how crazy Baiwu Yuanwu was, no matter how much he looked down on the combat effectiveness of the Red Army, he did not dare to take the entire fleet into the Yangtze River waterway with unknown hydrological conditions with a single eye. (To be continued......)

What is Self-Dry Zhao? From: Mr. Lu Xun's Ah Q biography "You are also worthy of the surname Zhao"

It means that he is obviously a dick, but he thinks he is a powerful Zhao master, one qiē thinks about problems from the perspective of Zhao Lao's interests, and one qiē thinks about the interests of Zhao Lao. But I forgot that I was just a "you are also worthy of the surname Zhao".
