With the weakening of the Huaxia Air Force, the Japanese army was still afraid of Nanjing and avoided fighting.

The Japanese army not only sent fighter planes every day to take the initiative to invite the skies over Songhu, but also sent waves of Type 96 land attacks from the Japanese mainland and Taiwan's airfields, continuously attacking the landing sites in the Songhu area, and even frequently sneaking up on Hangzhou or Suzhou.

Therefore, the Huaxia Air Force has to fight without fighting.

Fortunately, the more than 100,000 Japanese troops that had landed were also a little weak, and the combat effectiveness that had erupted in order to survive had also been exhausted as the strategic environment became safer and safer.

Matsui Ishine, Fujita Shin, Yoshika Ryosuke, Yamamuro Sotake, and other front-line generals sent reports to the Japanese base camp one after another, requesting that new reinforcements be drawn from the Japanese mainland as soon as possible.

The base camp is also very considerate of the difficulties at the front.

100,000 Japanese troops seems to be a lot, but the strategic depth of the beachhead is too small, many heavy weapons cannot be used at all, the air force is engaged in attrition with the Huaxia air force, and the naval fleet is afraid of unnecessary losses, so it only symbolically provides long-range fire cover.

In the eyes of the base camp, every day that the landing force held out was a great victory, and the number of casualties was still a small matter.

The Songhu battlefield was crucial, and immediate reinforcements were the only option for the Japanese army.

On August 28, the Japanese army in North China completely occupied the south and north passes (Zhangjiakou), and due to their own heavy losses and the urgency of the Battle of Songhu, the follow-up soldiers and all kinds of supplies were depleted.

Therefore, the Japanese base camp ordered the Japanese troops in the Pingjin area to temporarily stop the momentum of continuing the attack, and they must wait until the Songhu battlefield is stable before launching a new round of offensive.

In the early morning of 29 August, the 5th Brigade of the Japanese Field Heavy Artillery, the 15th Independent Field Heavy Artillery Wing, the 12th Independent Engineer Wing, and more than 20,000 additional troops, under the strict escort of the Combined Fleet, carried out the second wave of supplementary reinforcements to the Japanese troops that had landed in the Wusongkou area.

Originally, in the sequence of this reinforcement, there was also the 3rd Flying Regiment of the Army Air Corps.

However, because the positions currently occupied by the Japanese army are too biased towards the beach area, and the strategic depth is seriously insufficient, even if a temporary field airfield can be built, it will be a relatively dangerous thing, and once it is covered by the Chinese heavy artillery group, there is nowhere to escape.

Therefore, the matter of the flying group had to be temporarily abandoned.

After learning of this new movement of the Japanese army through secret channels, Nanjing had to suspend the original counterattack plan, and instead let the front-line troops hold on while quietly fine-tuning the attack direction of the heavy artillery cluster.

After receiving the order, the submarine force deployed near Hangzhou Bay immediately dived out, quietly ambushed the Japanese reinforcement fleet, and let the newly reinforced fighters in western Sichuan prepare for the second wave of strikes, this time with the purpose of blowing up the Japanese battleship.

Huaxia's submarine force, founded in 1935, was one of the "special gifts" given by Berlin, Germany when Liu Yun and German technical experts jointly developed a new type of tank.

At the beginning, the unit had only eight U1 submarines (a product of the First World War).

It was not until the beginning of 1936 that Huaxia set up a Sino-German joint submarine headquarters in Hainan and Guangzhou, and repurchased 16 U2 submarines (products before World War II), whose scope of activities included the Taiwan Strait and the Bass Strait, and in early 1937, a secret submarine base was set up in Hangzhou Bay near Shanghai.

Soon after the outbreak of the "August 13 Incident", the Japanese fleet began to blockade the coast of China.

However, the Japanese Third Fleet posed a greater threat to Songhu, and several of Huaxia's own broken ships were about to sink themselves near the Jiangyin fortress, so the Nanjing Military Commission had no choice but to order nearly half of the submarine force to go north, and after passing through layers of blockade lines, arrive at the secret base in Hangzhou Bay on 22 August.

On 23 August, Huaxia fighters attacked the Japanese aircraft carrier in a battle that happened suddenly, and it was about 100 nautical miles away from the secret base in Hangzhou Bay, and when the submarine force arrived, the war was over.

The naval headquarters did not dare to let the submarine pursue the Japanese fleet, and then rescued more than 30 pilots, which was highly praised by the Nanjing Military Commission.

Moreover, due to the appearance of submarines, the arrogance of the Japanese fleet has also decreased a lot, and it has to pay attention to the safety of the ships themselves.

After all, the submarine force has never seen blood, and it is not a dry city of the country.

In the early morning of August 29, the Japanese fleet once again relied on the protection of the night, unscrupulously transporting troops and technical equipment, after all, it was on the verge of the coastal waters of China, and in order to ensure the safety of materials, it walked very slowly all the way, and was ready to prevent a sneak attack by Chinese submarines.

It was not until they arrived at Pudong Beach that there were still no accidents that the Japanese breathed a sigh of relief.

However, at this moment, the dark night sky was pierced by lightning, and there were faint screams of breaking the sky.

In an instant, the entire landing beach was covered in fireballs that shook the ground, and the whole night became like day, and then turned into a sea of fire.

The Japanese troops who landed all fled in a hurry, but unfortunately there was no place to hide on the slippery beach, and they couldn't help but let out terrible screams, although the night was still heavy, it still could not hide the bloodshed of the battlefield.

Under the cover of heavy artillery, there was purgatory everywhere, and even ships of all sizes were frightened and fled.

The Japanese warships needed to be evacuated urgently, and only half of the problems were delivered, completely ignoring the tens of thousands of soldiers who needed to land, and many heavy equipment needed by the army were thrown into the sea, and the worst thing was the Fifth Heavy Artillery Brigade, more than a dozen large-caliber heavy guns, all of which were dumped into the sea.

It is estimated that even if it can be fished up in the future, it will be useless, and the worst thing is that there are still the most scarce 203 mm and 240 mm heavy guns.

But the god of doom still did not forgive the Japanese fleet.

I don't know if it's because it's too dark, but the fast and light destroyer has already moved away on its own.

Several 10,000-ton transport ships, because they have not had time to unload personnel and equipment, have a deep draft and a very slow speed, so they are faintly at the end, and are listed as targets by the sea wolves of China.

The countdown to the day trip to the Dragon Palace begins.

The Chinese sea wolf participating in the hunt, a total of four as many as four, all of them are German IIB submarines, the ship has a crew of 25 people, a length of 42.7 meters, a width of 4.1, a draft of 3.8 meters, an underwater displacement of 328 tons, and an electric-internal combustion 2-shaft propulsion engine with a power of 1060 horsepower.

The submarine has a surface speed of 13 knots, 6.9 knots underwater, a maximum range of 3,100 nautical miles, a theoretical depth of 120 meters, and it is equipped with three 533 mm torpedo tubes, with a total of 5 torpedoes in reserve, and 12 mines can also be optionally carried.

They are the most ferocious predators in the dark.

This attack was the first attack of the Huaxia sea wolves, and they were still very immature rookies, so they were relatively timid, and they only dared to go for trouble with the transport ship.

During the whole attack, as written in the textbooks, two submarines were used against one transport ship, and in order to save time and facilitate their own escape, they fired three torpedoes at once in the shortest possible time, and then immediately and urgently dived without even daring to see the results.

Taking advantage of the chaos of the Japanese army and the cover of night, the sea wolves quietly sailed towards Hangzhou Bay.

These cowardly sea wolves ran away, but the results were not bad.

Of the 12 torpedoes fired, almost all of them were bloody, and none of them were the "Sapporo" and "Tsukawa" transport ships, which were hit by 10 torpedoes, which immediately exploded in a series of explosions, and soon sank into the sea, and all the 3,000 or 4,000 landing soldiers and their equipment were fed to the fish.

Even the "Big Feather", which was not far away, was affected and took a hit in the part of the propeller.

At the beginning of the day, Huaxia's heavy fighters immediately pounced on the battle area.

The landing area was bloody, the severed heads and stumps were scattered all over the ground, and the other surviving Japanese soldiers were already prostrate on the ground in despair, not daring to move, and the entire beach was bloody, and even the sea breeze above was faintly carrying the smell of blood, so that the pilots who passed by almost vomited on the spot.

However, the affairs on the ground are still managed by the army.

The real target of the heavy fighters was none other than to assist the Japanese warships that landed last night.

They had already been informed by the submarine forces that they "maybe" sink several Japanese transports.

Regardless of whether the attacked enemy ship sank or not, other ships of the Japanese army would go here to search and rescue, so among the nearly 50 heavy fighters, there were more than 20 anti-ship dive bombers.

When the group of planes arrived at the sea area of battle, they saw a large number of dead bodies floating on the sea, and some of the surviving soldiers who had fallen into the water, as soon as they saw that a plane had arrived, they didn't care whether they were their own people or not, they tore off their white shirts and screamed desperately at the plane, as if they had seen a savior.

But the pilots, after all, are Chinese.

Instead of being Japanese devils, they still did not lose their humanity, so they did not shoot at these Japanese soldiers, but reported the situation to the headquarters in Nanjing, and continued to expand the search area in an effort to find the enemy warships that had been caught.

Unfortunately, the transport ship "Owa" was discovered.

Completely ignoring the damage to its own power, it was trying to escape with all its might, and its face was suddenly dead when it saw the arrival of the Huaxia group.

Whether or not to blow up and sink the ship, there is a dispute among the pilots.

Because there were no other Japanese warships within a few dozen nautical miles around, and this warship was a lone warship, Wing Commander Li Weili thought that they should be given a chance to surrender, so after a burst of demonstrative strafing, he ordered the ship to surrender immediately through the radio on the plane, and the Chinese army gave preferential treatment to the prisoners.

It may be that the soldiers on the "Big Feather" couldn't lose their sons, so they didn't reply for a long time.

In desperation, Captain Li had no choice but to order a bomber to drop a 750-kilogram bomb not far from both sides of the warship.

This kind of bombing has a technical term, called "straddle bombing".

The straddle bombing also means that the Huaxia Air Force is about to launch a formal dive attack, and there is a chance that the ship will be sunk.

"Straddle bombing" is derived from the principle of firing from battleships.

In the era of dreadnoughts, the enemy and the enemy often fired from a distance of more than 10 kilometers, and the sea was different from the land, and the accuracy of the warship's artillery fire was greatly affected by the fluctuations of the sea water.

Therefore, when shelling an enemy ship, it often requires a certain probability, and the best shelling situation is the phenomenon of "straddle shooting", that is, two shells in succession, just falling in front of and behind the hull of the enemy ship, or one left and one right, just like the two feet of a giant, just across the hull of the warship and get its name.

In the event of an engagement between dreadnoughts, once the warship is "straddled", it means bad news.

Because with the increase in the number of shelling of enemy ships and the acceleration of the firing speed, the accuracy will also increase, resulting in the probability of shells falling within the spanning firing range, and it will also rise in a straight line, so as to accurately hit the enemy ship, it is only a matter of time, and later it evolved into aircraft dive bombing, which is also the same.

Now that there is a "cross-bombing", the "big feather" transport ship is no longer good at pretending to be stupid.

Because there were nearly 2,000 lives on the transport ship, once it was sunk, it would be all over, so the white flag was slowly raised, and obeyed the command of the Huaxia fighters, and began to sail towards the designated port, its speed was like a turtle crawling.

These people may be unwilling, or they may be waiting for the rescue of their own warships.

About an hour passed, when the transport ship was approaching Hangzhou Bay, nearly 100 warplanes flew from the northwest of the East China Sea, and on them were the red sunburst symbol, which was the Japanese army's own fighter planes.

Li Willy and others were also nervous.

They only had nearly 50 fighters, half of which were bombers, and in the face of nearly 100 Japanese fighters, once they fought, the odds of winning were indeed too low.

The Japanese army did divide half of the fighters and isolate the Huaxia Air Force, and then ordered the remaining fighters to fly to the transport ship, and it was only then that everyone found out that these fighters were all Type 96 ship explosion (torpedo attack aircraft), and the target was the "Da Yu" transport ship.

Their purpose was not to rescue the transport ship home, but to sink it on the spot so that it would not be captured by the Chinese army.

Li Weili and the others themselves could not be protected, so they had to let it go.

The hideous Type 96 ship explosion, like a wasp, showed its tail thorns one after another, and flew towards the half-paralyzed transport ship, and after a sprint, dozens of white waves appeared on the sea, and the target was directly aimed at the "Big Feather".
