The trenches not only had twists and turns, but circular trenches that could accommodate an infantry squad were dug every thirty meters. Even if nearly ten thousand people worked together, it was not an easy task to complete within 20 hours.
What's more, more than two rows of real field trenches were built horizontally more than 200 meters away from the Huangpu River.
Yes, the curved field trenches extending from Cangcheng in the west of the city to the Huangpu River were not used to block the enemy, but were used to withdraw the 152nd Jieguji Regiment that was blocking the Japanese invaders who crossed the Huangpu River.
Under the threat of Japanese naval guns and aircraft, placing the army on an unobstructed plain and marching 12 miles away would almost put the officers and soldiers to death. But with field trenches that can protect against artillery, it is different.
.
Not to mention that it is impossible for artillery to accurately blast into a trench less than 2 meters wide. Even an aircraft flying at an ultra-low altitude cannot succeed so easily. Besides, do you really think that aircraft are invincible? When it is lower than 150 meters, it can focus fire
The firepower of light and heavy machine guns is enough to rid the aircraft of holes.
A propeller aircraft's speed of more than 400 kilometers is really much slower than a bullet. If we put it in the future, jet engines equipped with thrust engines of up to ten tons would hardly need to fire, and they would hit low-altitude enemies at supersonic speeds like this.
You can shock people to their core. Let alone using a gun, you have the ability to stand up.
With this huge manpower-consuming field trench, it is enough to ensure that most of the infantry regiments after the blockade can successfully withdraw to the positions in Cangcheng and Songjiang City. After all, the purpose of the blockade on the Huangpu River is not to block tens of thousands of Japanese troops in Jiangna
It's just a matter of delaying time and killing more Japs at the same time.
There are still three infantry regiments in the city, but they are not idle. Each infantry squad has selected two people to work with the company commander to familiarize themselves with the dense passages and exits in the underground pipe network in their respective defense areas. They must know the underground
Mark the corresponding positions on the ground with a map. Otherwise, if you originally wanted to spank the Japanese soldiers, but instead led your brothers to get in front of the Japanese guns, that would be very bad.
Of course, in order to make it easier for the officers and soldiers of each department to go out to fight the Japanese, each exit and the buildings above it were simply marked and explained in the Sichuan dialect by the 43rd officers and soldiers, but that is probably only understandable by the people of Sichuan Province.
, let alone the Japanese, people from other provinces will probably get numbness after seeing it.
For example, "beat the dog day and make a melon baby", which means that the exit above is very hidden, and you can go out to fuck the little devil. Another example is "bloody butt dripping", which means that the exit is dangerous, and you have to be careful if you want to go out, so as not to be caught by the Japanese
It's overcast. Things like this are enough reminders for the 43rd officers and soldiers who are 95% from Sichuan.
The buildings and lanes above the exit were named after the famous mountains, rivers and rivers in Sichuan Province by these Sichuan people who had not read much. A small alley might be called "Jialing River", and a two-story building might be called "Jialing River".
Perhaps it is "Emei Mountain", and the inconspicuous residential houses may be "Qingcheng Mountain".
This led to the fact that in the future, the orders issued directly by the battalion headquarters through the public broadcasting of the underground pipe network were basically: "Second Company, bring me back to Qingcheng Mountain after dark. The fourth platoon leader of Gou Ri, Jialing River is your defense zone. If you lose it,
I will kill you."
This made it sound like they were commanding the battle in Fang Qichuan Province right here. Even the 43rd Army Headquarters even used this code name to mark it on the city defense map. The Army Lieutenant General also followed this example when asking about the battle status of each regiment, and even
In order to save time, he did not hesitate to send clear text messages when the phone was unavailable.
This confused the Japanese troops who had already entered the city and worked hard to penetrate the 43rd Army's communication network! Does the small Songjiang have so many mountains and rivers?
Moreover, at Yu Xiancheng's suggestion, in order to prevent the Japanese army from using poison gas to attack the underground pipeline network, the 43rd Army distributed all the more than 2,000 gas masks in the army to the pipeline network, and the commanders of each regiment were responsible for the defense according to the
Regional distribution, and at the same time, expand the air outlets. Fortunately, when the underground pipe network was being constructed, a large number of air outlets were designed to prevent methane poisoning, unless the Japanese army that occupied the entire city blocked these air outlets one by one.
, otherwise it would be wishful thinking for the Japanese army to flood the underground pipe network throughout the city with poison gas.
Of course, if the Japanese army can occupy the entire city and let them block the air outlets, it will almost prove that all the 43rd Army has been killed and their combat mission is over.
In addition to the officers and soldiers who were busy familiarizing themselves with the terrain and drawing maps, the three infantry regiments on the ground were also busy. They had to lay out the city wall fortifications on the second layer of defense. The sandbag fortifications on the city head were actually not very large.
From the beginning, the infantry regiments did not plan to place many troops on the top of the city wall.
This is not the era of cold weapons. You can kill a large number of Japanese invaders by hiding behind the city walls and firing cold shots. The howitzers of the little devils may not be so accurate in hitting the city wall that is less than 3 meters wide, but the infantry cannons of the little devils
It is definitely a weapon for siege. Placing a large number of troops at the top of the city is to deliver food to the Japanese. These colonels will not be so stupid.
Don't think that the Japanese army's victory in North China and East China battlefields was due to how strong their infantry was. They could defeat the Chinese army again and again. It was because they had enough artillery. Perhaps their marksmanship, stabbing skills, and physical fitness were not enough.
They are stronger than the Chinese soldiers, but in terms of survivability on the battlefield, the Chinese soldiers of this period are really no worse than them, or even stronger.
The Japanese, except for competing with China in Songhu five years ago and Rehe four years ago, have not participated in a war for a long time. As for the Chinese army, the domestic situation has been unstable for so many years, and warlords in various provinces are fighting each other for their own interests.
They are all veterans who have experienced war. Especially the Sichuan Army. From 1925 to 1935, there were constant disputes between the bosses of various factions. It was common for you to beat me and kill me. Although the intensity was far less than the current Sino-Japanese War, it was a unique skill to save lives on the battlefield.
But I learned a lot.
There are many such veterans in the Sichuan Army. They don't love the army very much, but they are paid as soldiers. For the veterans, it is just a job. They have been doing this for the past ten years.
Yes, no matter who you serve as a soldier, you will support your whole family with military pay.
It can be said that they are the prototype of China's first generation of professional soldiers.
The same goes for colonel commanders who have risen from platoon commander to company commander. According to the actual situation, no matter how this battle is fought, due to the disadvantages of troops and firepower, it is bound to fail. However, the army commander has given the order,
Even if the entire army is wiped out, we still have to complete the military order of blocking the enemy for three days and nights. Since we can't run away, we can only fight hard, but if we fight hard, we can't die in vain. After all, we would rather die than drag the little Japanese as our backs.
Isn't it?
In fact, this is also caused by the seemingly contradictory personality characteristics of Sichuan people.
Patience is a characteristic of East Asian civilizations, and the people of Sichuan Province are typical examples of patience. On the one hand, this character is developed through their long-term struggle with the harsh natural environment. In production and labor, they rely on this spirit to "
"Desire to compete with God" shows the heroic spirit of man's determination to conquer nature and not bow to nature. But on the other hand, the people of Sichuan Province who are accustomed to living in a relatively superior natural environment have also developed a kind of complacency with the status quo.
With a happy-go-lucky character, as long as the basic life can be maintained, they are generally unwilling to abandon their original way of survival and life trajectory. Therefore, even if they are oppressed and bullied, most of them will bear the word "tolerance", endure it again and again, and even bear the burden of humiliation.
If we say that people in the north are like dry firewood, they draw their swords to help when they see an uneven road, are dissatisfied, and rise up against the crime. People in Sichuan province are like wet wood "pimples". They endure silently at first, until they hide in their bones what Yu Qiuyu calls a magnificent and astonishing rebellion.
Breaking out of the ground is like the Yangtze River rushing out of the narrowest gorge - Kuimen. It goes eastward and vows not to look back. Whatever Sichuan people do is always unknown at the beginning. It is only at the critical moment that they become vigorous and sparkle.
.
The people of Sichuan Province, who were in a life-and-death crisis, had undoubtedly aroused rebellion in their hearts. Under the command of the infantry commanders, they actually began to dig up the ancient Songjiang city wall that had existed for hundreds of years. They wanted to build a six-meter-high base with a wide base.
The six-meter ancient city wall became the first fortress. Heavy machine gun fortifications were built within the city wall and all heavy firepower points were placed within the city wall.
Although most of the blue bricks on the wall of Songjiang Ancient City have peeled off, the reason why the wall can withstand hundreds of years of wind and rain without falling down is not the bricks, but the soil of the city wall itself, which was mixed when the wall was built.
It is made of glutinous rice juice. Perhaps it is not as strict and cruel as the Tiefu Xiongnu who built ten thousand cities. If an awl can penetrate an inch of the earth wall, then this section of the wall is an unqualified project, and the people who built this section of the wall will have to beheaded collectively.
, but judging from the bits of dirt that fell off after just a few iron pickaxes, if the ancient city wall that has experienced hundreds of years of wind and rain does not encounter war, there will be no problem at all standing on the land of Jiangnan for another two or three hundred years.
.
In other words, it is absolutely no problem to use this as a fortification to fight a war with the Japanese.
Nearly 5,000 people surrounded this section of the ancient city wall of Songjiang City and began to dig out the wall. According to the firepower matching design, a hiding hole was dug after the city wall was separated by hundreds or even tens of meters, ensuring that one heavy machine gun and two light machine guns could be placed.
Although this kind of firepower point has many blind spots due to the shooting boundary, it is definitely enough to pose a threat to most infantry trying to approach the city wall 50 meters away.
But instead of hollowing out the entire city wall, the thickness of the soil layer above must be at least 3 meters, and the thickness of the wall around the firing hole facing the Japanese firepower point in the front must also be at least 1.5 to 2 meters, so as to ensure that the firepower point faces 70 mm
Infantry artillery or 37mm anti-tank artillery have sufficient survivability when shelling at close range. Although in order to increase the larger firing range, the left and right width of the outermost trumpet of the shooting hole reaches at least one meter and the height reaches half a meter, but the officer
We are collecting iron sheets and steel plates all over the city to give shooters more protection. Unless the Japanese heavy machine gunners are so magical that they can accurately target the impact point of their bullets to a range of 0.5 square meters, they will not be able to easily hit them with the 6.5-caliber bullets of the Japanese Type 38 rifle.
Dead machine gun shooter.
As for the Japanese army's larger-caliber cannons, if they can accurately hit a firepower point of no more than ten square meters at a distance of one thousand meters or even two thousand meters, it will only be a loss of life. And those larger-caliber cannons and naval guns or
Not to mention aerial bombs, they are powerful enough to destroy a section of the city wall, but the prerequisite is that they can hit the city wall with incomparable accuracy.
Many cities have been captured, but I have never heard that the city walls were completely destroyed, even in the terrible era of hot weapons. This trick used by the 43rd Army is, don't say you may not kill me, even if you can kill me
Me, before you beat me to death, I have already made you shed all your blood.
What these colonels and officers are betting on seems to be risking their lives, but in fact, it is also a matter of probability. But how can you bet if you are incompetent? Those who dare to risk their lives on the gambling table are worthy of respect.

ps: I recommend the new book "Special Years" by the military tycoon "Yan Qiguan". Yes, it is Yan Qiguan who guest-starred as the commander of the guard company in this book. He used to hang out in the Marine Corps when he was young, and then he became like this
He has reached the peak of his life. How should I put it? There must be his own shadow in this book. I just don’t know if he dares to write about the many past events of picking up girls. I heard that his wife is a fan of his books. This is undoubtedly a sad story.
