The Red Army, which invaded the Japanese concession, did not attack in a hurry, but fought extremely steadily and with great planning. Simulating the "way of attack by the imperialist countries", a wall of fire in the sky was pushed through and a wall of fire on the ground was crushed, without giving the Japanese the slightest chance. With desperate stability and momentum, the defenders of the Japanese concession were crushed to pieces.

The infantrymen on both sides of the tank threw grenades at the houses on both sides of the street, and no matter whether there was anyone or not, each one could not spare one before entering the house to inspect it. This is the experience accumulated from many years of war, and it is also a bloody lesson obtained after attacking the Japanese concession, and it is also a repeated reminder from Lin Han and his superiors before the war. After all, the Japanese were no better than those straw bales of the artillery army, and although the Red Army had a great advantage in firepower, the defenders of each stronghold fought almost to the last man, and the battle had been fought for more than two hours now, with very few prisoners.

The buildings on both sides are constantly making a roaring explosion, when encountering a two-story building, the infantry will rush to the upper floor to check and occupy, before rushing in, they are greeted with a grenade, not every room can "blow up something", with bursts of black smoke coming out, occasionally "blinded" to it, you can hear the screams of the ambush soldiers hiding in the bomb, then the following infantry will throw more grenades, and then rush in to sweep any suspicious object.

This kind of walking along the street and throwing grenades one by one to clear the house is just the most "gentle" way to deal with it in the battle of the concession. More often than not, the infantry on both flanks violently blasted through the walls of these connected houses, using holes in the walls to enter the next room, thus opening up the entire street.

In fact, for the houses on both sides. The most convenient way to do this is to throw an earthen gasoline blasting and burning bow sheet into it, and if you throw it in and blow it up, the whole house will burn directly, and no one can hide it, and you can even rush in to inspect it. This frenzied weapon was a brain-opening street fighting weapon proposed by Lin Han, but the explosive incendiary bow was not invented in the whole of World War II, and the kind of weapon made by Tufa was extremely dangerous to the pitcher himself, and was not welcomed by the Red Army. So there was no chance to make an appearance.

And the flamethrower is a tall thing, and the flamethrower tank, which is a sharp weapon for infantry, because it is still in the process of development. The existing products are not too safe. They also did not appear in the Japanese Concession, otherwise Lin Han and Hannah would have sent them to the Japanese Concession for actual combat testing.

Today's Red Army is no longer the poor bastard of 1931 when there were no bullets. Before the start of the war in 1935, the Red Army owned the four provinces of Hunan, Jiangxi, Hubei, and Fujian. Lin Han's four-year aid came down. It has been done with bullet tube foot. The grenade tube was sufficient, and the planes, artillery, and tanks imported by the Red Army in large quantities by the artillery party headed by Song Ziwen generously sold livers and kidneys and carried foreign debts to aid the Red Army in large quantities, were already full of "foreign spirit." Before the Battle of the Concession. The political commissars on the front line repeatedly told the front-line soldiers that the Japanese devils in the concession were extremely ferocious, and they should never be economical when throwing grenades.

In the basement of Sun Yuan's former headquarters in Shanghai's Huajie District, Lin Shuai and a chief of staff who were in charge of attacking the Shanghai Concession were pointing at a huge model of the Concession map in the conference hall.

In order to take the concession along with the lì, the Red Army spent two years preparing before the Red Army. In addition to the detailed mapping of the maps by the Germans, the buildings and street layouts in the concession were also made one by one with full-scale models. The material of the model is all cork. Each building has its own individual numbered label.

In fact, the preparation of the model made by the Red Army was much larger than the model that was placed in the conference room, and the whole of Shanghai was "modeled" in this way at that time. However, the war of 1935 went beyond everyone's imagination, and before entering Shanghai, the Red Army military made the best preparations according to the worst plan, and who knew that Lin Han was out of less than 500,000 US dollars, and easily gave the Nanjing Nationalist Government the final blow with a silver bullet. The battle to enter Shanghai was completely a "receiving" operation. Most of the models prepared in advance were not used in the end, and the last ones to be used were the models of this small area of the concession.

After the Red Army invaded the Japanese Concession, the troops on the front line constantly fed back the progress to the headquarters, and the model of the blocks in the Japanese Concession area was constantly planted with small red flags.

Lin Shuai, who is located at the front-line headquarters, was able to get the latest news from the front line so quickly, thanks to the radio walkie-talkies for infantry provided by Lin Han.

Chen Yu was an infantry communicator who followed the assault team, and the radio communicator on his back was the first generation of transistor frequency-hopping walkie-talkies provided by Lin Han, weighing less than ten kilograms, and although the communication radius was only 12 kilometers, it was the most popular equipment in the attacking Red Army. Once the remaining Japanese firepower points in front are discovered, as long as you pick up the walkie-talkie and report the coordinates to the headquarters, a few minutes later, the artillery support in the rear will soon arrive, and the "hard bones" in front will be directly smashed in an instant.

In the battle to enter the concession, the Red Army on the front line had already begun to use this tactical means of calling for rear artillery support, which was full of later "American imperialist models". In addition, they can also use the guò walkie-talkie to communicate with friendly forces attacking from other directions in the vicinity in order to cross-support each other.

After years of hard work, at the end of 1934, the Germans finally manufactured a qualified germanium semiconductor transistor in the real yàn chamber - which was only a laboratory production, and there was still a great distance from industrial mass production. In the spirit of combat testing, the small number of transistors produced in these laboratories were all used to make radio equipment, and then sent to China for combat testing, and Shanghai was the first time they appeared to use it.

Hannah was not afraid of the technology of transistors leaking to the Soviets, in this era, the difficulty of transistor manufacturing, lighting up this technology tree, just like the later generations to build aviation jet engines, it takes the complete perfection of the entire technology tree system to do. On the German side, supported by Hannah's theoretical knowledge of manufacturing, and assisted by non-human superpowers, it took a full five years to barely manufacture a qualified transistor in the laboratory, but there is still a long way to go before large-scale industrial mass production -- historically, there was a gap of nearly five years between the birth of the transistor in the Bell laboratory and the large-scale launch of transistor radios with four transistors.

The commandos of the Red Army were doing large-scale interspersed battles in the concession. Each commando carried such a lightweight radio walkie-talkie on their backs. In addition to being in constant contact with headquarters, assault units can also communicate with each other.

This set of equipment has just been developed in March this year, because the transistors can only be tested and produced in small quantities, and the first batch of products was only made 36 units, which were just manufactured at the request of Lin Han, and all of them were transported to China by means of air transportation to Lin Shuai for trial. Twelve of the second batch were also sent to China before the war, but all of them were used by the Mock Wind Eradication Gang, which was secretly operating in Shanghai, and now all of them are in the Public Concession.

In the underground command center, combat information from the front line is transmitted back to the command center through guò radio waves, which allows the front-line command officers to know the progress of the front-line troops anytime and anywhere.

"The Ninth Company's attack in the thirteenth area is blocked! The Japanese laid out anti-Japanese artillery there. Their tanks were hit. It is no longer possible to move forward. The Japanese laid out three crossfire points there, in three areas of 147, 151 and 160, and the battle defense guns were in positions 151. The Ninth Company asks us for heavy artillery support! ”

Lin Shuai, who was constantly stuffing fried soybeans into his mouth, glanced at the topographical model of the concession in front of him. Those three crossfire points were three three-story buildings. It is arranged in a zigzag pattern. They were well positioned, and the Ninth Company, regardless of which line of assault it was from, was subjected to crossfire from three directions.

"It's high-tech. There won't be wars, that's a bad thing! ”

Lin Shuai showed a dissatisfied expression, threw a soybean into his mouth, and then ordered: "Allow support!" ”

A staff officer on the side pointed to the map model and interjected: "These three locations have been shelled many times before, but they will soon resume firepower. Our artillery positions were not well placed and the effectiveness of the strikes was not good, especially the target No. 151, which was backed by a small hill and just formed a dead end. The Japanese should have used the refueling method here, and when we shelled, the main force hid in the basement to avoid the shelling, and only came out to counterattack when attacking, so the killing effect of each shelling was not good. ”

"The refueling tactics used on Shangganling?"

Lin Shuai muttered in his heart, and threw another soybean into his mouth. When he was in the Soviet zone, Lin Han mentioned similar tactics when talking to him about the different tactics used by the PLA against different opponents in different historical periods.

Sammo pointed to another location on the map simulation and said: "Here, the 4-story building in Area 127 has been taken by the Sixth Company, as long as the Type 92 infantry gun is dismantled and transported upstairs, you can directly aim and bombard these three areas here, and there is no shooting blind spot." I set up several temporary artillery positions on the upper floors of the building, let the men of the 6th Company suspend the attack and repair, transport a few guns up, and use their communicators to communicate directly with the 9th Company, and they will provide artillery support at any time as needed. ”

Fifteen minutes later, numbered 127 on the map model, the actual number is several windows on the fourth floor of the "Nissan" building,

The muzzle windows of the four Type 92 light infantry guns protruded. The Type 92 infantry gun weighed no more than 200 kilograms, and the Japanese profiteers smuggled it to Lin Han for money, and Lin Han took one and sent it to Germany, and Hannah copied a batch and used it in large quantities to aid the Red Army, which was a very popular light infantry artillery in the Red Army. After dismantling the emperor, a few people can carry it to the tall building, and then quickly assemble it. (Note: There was such a scene in the movie Pingjin Battle)

"Is the commander of the Ninth Company? I'm Zhang Xiaoshan from the Sixth Company, and I'm already in place here, so I'm waiting for you to fire! ”

Company Commander Zhang Xiaozhang of Bearded Zara was holding the Siemens frequency-hopping walkie-talkie provided by Lin Han to communicate with the company commander of Guzidi more than 700 meters away on the battlefield.

Gu Zidi: "Open the gun, his Japanese old lady!" ”

A minute later, four light infantry guns on the fourth floor began to fire in turn.

Half an hour later, the staff officers in the command headquarters replaced the white flags on the three fire points with three small red flags.

The transistor infantry radio walkie-talkie was the most "murderous" time-lapse equipment provided to the Red Army by Lin Han, the traverser. After equipping the troops, the front-line troops all applauded, and they were the most shown to be the best equipment. After this battle, the Wuhan headquarters asked him for the most equipment, which was this Siemens walkie-talkie.

Under the cover of the tanks, the centering of the walkie-talkie adjusted the dispatch, and the troops of the Red Army attacking the concession were interspersed with a desperately steady speed. Before dark, the entire Japanese concession was divided into several small pieces that were not connected to each other. and separate it from the public concession. At the strong request of the "friendly forces", the British troops in the public concession fearfully sent three companies into the Japanese concession to support. As soon as these three companies stepped into the Japanese concession area, they were immediately covered by shells from the Red Army artillery positions in the distance, and were directly annihilated by the artillery on the street.

In the city defense battle, one of the biggest problems on the concession side is that there are many pre-arranged eyeliners in Lin Han's own concession. It was good that the garrison that the garrison went to support was hiding in the building, and as soon as it appeared in an unobstructed section of the road, it was immediately covered by these people who directly guided the artillery positions on the Red Army's side to open fire through radio walkie-talkies.

And the same type of wireless walkie-talkie was used to guide the shooting of the Red Army artillery positions. At that time, the underground party of the Chinese Communist Party lurking in the public concession became a hand. Holding a telescope in one hand. With a walkie-talkie, he directly commands and dispatches the artillery positions in the distance to guide the shooting. The three companies of nearly 500 men sent out by the British finally mustered up the courage to send out reinforcements were completely covered by artillery fire, and not even half a human hair escaped.

"Victory belongs to those who are prepared."

Two years ago, the Germans surveyed and mapped in Shanghai. The location of the entire concession area has long been clearly marked on the map in advance. The various shot counts are listed in a table. Just quote the relevant place number. The artillery positions in the rear were selected according to the chart, and the first wave of shells could be fired in 30 seconds at the earliest.

This is a digital age of combat that only later appeared, with scouts directing artillery fire from the rear. In this era, it was also reproduced once by Lin Han cottage.

The British army is also very different. The native army located in Europe and Europe has a very high will to fight in the war, and the overseas colonial troops based on the Indian Asan are also friendly troops who are difficult to move like a mountain and die friends do not die in poverty, and spare no effort to sell their teammates for their own survival. After the troops sent reinforcements were directly blown down on the road by the Red Army's artillery friends and the naval guns on the Huangpu River, although the Japanese troops in the Japanese Concession cried and begged the British many times to "cheer for the brothers", the garrisons in the Public Concession said that they were unwilling to send any more troops to support.

By 10 o'clock in the evening, the gunfire from the afternoon to the evening had basically stopped, and by this time the red flag had been planted in the Marine Corps Headquarters building in the Japanese Concession, and after five hours of hard fighting, the Red Army completely annihilated 3,500 Japanese troops in the concession (1,000 were regular troops, 1,500 were armed expatriates, and the rest were mobilized auxiliaries), but they also paid the price of more than 1,200 casualties.

After taking the Japanese concession, the Red Army did not take advantage of the situation to attack the British concession, and Lin Shuai ordered to replace the front-line troops who had been fighting hard for most of the day with the reserve troops, and then ordered the whole army to repair and wait for dawn.

The most difficult of the Shanghai concessions, the Japanese concessions, have been taken, and the remaining public concessions are only in the bag. There are too many important facilities in the public concession, and it is best to solve the problem of the public concession by forcing it down.

Although the fighting ceased for the time being, negotiations between the Red Army and the Public Concession continued. With the British as the representative of these foreigners, they vainly wanted to continue the negotiations and delay the time, so that Taiwan's Third Fleet could rush to the Bund in Shanghai to create a miracle.

Tired of the Red Army negotiators who were endlessly acting with the British, they took a wireless walkie-talkie to contact Lin Han on the Huangpu River on the spot.

A few seconds later, there was a burst of artillery fire on the Huangpu River, which had finally calmed down, and the three batteries on the Pinghai opened fire on three different targets, and the public patrol room, the HSBC Bank building, and the Shanghai Post and Telecommunications Building each fired two shots.

Except for the public patrol room, which uses explosive bombs, the remaining two buildings are filled with solid trainer shells, but even so, the splash of bricks produced by the trainer bullets on the wall still injured the British soldiers who were hiding inside. Only warships like Lin Han and Li Huamei can accurately manipulate artillery to shoot directly and avoid causing more damage to the public concession.

As for the two shells that landed in the public patrol room, they killed and wounded 200 Indian soldiers and several British officers at once, and Lin Han was the target who picked the most people.

After the demonstration by force, the representative of the Red Army slapped the table and said to the face in front of him with a frightened face:

"The history of the concession must come to an end in China! There is no room for compromise on this point! It is important to remember that Britain and Japan are far from China, and our Red Army is the closest to you. Before six o'clock tomorrow, you can decide whether you want to leave China as a corpse or leave China alive. ”

In the public concession, I spent a restless night smelling the fragrance of human flesh constantly drifting from the Japanese concession.

In order to prevent the foreigners in the concession from having a good night, the Red Army set up loudspeakers on several small boats on the Huangpu River that night, approached the shore, and made a high-pitched broadcast to the public concession all night, making the foreigners in the entire concession unable to sleep peacefully all night.

Finally, at six o'clock in the morning of the next day, under the tremendous military and mental pressure of the Red Army, the Public Concession announced its surrender after receiving a guarantee from the Red Army that the lives and personal property of the foreigners in the concession were safe.

Then the Red Army took over the public concession in its entirety, and the first to occupy the major banks was the major banks. With the exception of Bank of America and ABN AMRO, the rest of the banks were directly occupied and seized.

In the face of the angry representatives of Britain, Japan and France who threatened war, Peng Shuai said to them domineeringly:

"We have long been at war!" (To be continued......)
