The big construction site in Songjiang is still burning the midnight oil.
When you are tired, you can lie down by the campfire, smoke a cigarette and take a nap for a few minutes. When you regain some strength, you can get up and start working again.
Everyone in Songjiang City is squeezing out the last bit of energy for their future, because they still want to go home. Although the chance is slim, why not give it a try! If you miss tonight, you may not even be qualified to fight.
there is none left.
The entire Songjiang City is like an armed fortress, built visibly to the naked eye.
The firepower structure planned by Tang Dao is gradually taking shape.
Countless trenches connected the houses in the blocks and extended to all parts of the city wall.
The six large air-raid shelters are like big spiders. The seven or eight trenches extending from the air-raid shelters are like long spider legs, winding and extending to all parts of the city. The six infantry regiments of the 67th Army will use these six
Large air-raid shelters set up separate defense zones for the garrison cave and the command center.
The other two infantry regiments serve as supplementary regiments. If the front-line infantry regiment suffers too many casualties, they will step in to at least allow the front-line infantry regiment to breathe a sigh of relief.
Six firepower points were dug into each city wall. The interior was supported by steel plates and logs. It used an infantry cannon or rapid-fire gun as the main firepower, supplemented by two heavy machine guns as auxiliary firepower.
Above each firepower point, that is, on the city wall stacks, there are reinforced sandbag fortifications as infantry bunkers, which are enough for two infantry squads to enter. In order to prevent the city wall from being heavily shelled by the Japanese aggressors and causing excessive infantry losses, behind each infantry bunker
Traffic trenches were built. Only when the Japanese army stopped shelling the infantry and started attacking, the infantry would climb up the city wall from the communication trenches.
Despite the fact that there were up to six infantry regiments defending the four city walls, in fact, the firepower points inside the city wall plus the positions above the city wall meant that the number of troops invested at one time was only six infantry companies.
A defensive war is a war of attrition.
Not only weapons and ammunition are consumed, but also human lives.
Tang Dao's conclusion is cruel, but it is proof of the final results of several large-scale urban defense battles in World War II.
A few years later, the famous Battle of Grad broke out in the land of red polar bears. The two warring parties invested more than 2 million troops and killed more than a million people. The casualties in one day were tens of thousands, and these were just soldiers.
Of the 850,000 residents who failed to evacuate the city, only 1,500 remained after the war.
Compared with the kind of battlefield where just looking at the numbers can make one's hair stand on end, the city offensive and defensive battle in which China and Japan currently invest no more than 100,000 troops is simply child's play.
However, consuming materials, consuming lives, and consuming all the courage you can think of is the essence of urban defense warfare.
The infantry regiments of the 67th Army are all standard regiments. Each regiment has a strength of 2,500 people. The six infantry regiments have more than 15,000 people. Calculated using the coldest human life formula, it is enough to consume 15 rounds.
If the exchange ratio between the offensive and defensive sides is 1:2, if the Japanese army wants to consume all these more than 10,000 people, I am afraid that it will have to pay for a reorganized division to accompany them. The 6th Division has the title of "Empire Double B"
Which one of the 18th Division has such courage?
As for the scumbag of the 114th Division, Tang Dao didn't count them at all. A division commander who only dares to bring an infantry brigade here is worth paying attention to.
In addition to the infantry, the most important thing is of course the artillery, which poses the greatest threat to the Japanese army.
The 26th Division contributed its last four infantry guns, and Lieutenant General Wu did not hesitate to fill them in the firepower points inside the city wall. However, the two mountain guns, which were regarded as treasures, did not pay much attention to them.
The reason is that the 67th Army has no shortage of mountain artillery. There are 48 artillery pieces in three mountain artillery battalions and one field artillery battalion. The proudly raised muzzles made Commander Guo's eyes turn green and he was almost envious.
Naturally, they took advantage of the situation and gave the two mountain cannons to the Sixing Battalion to take away. The 'rich' 67th Army did not need them, but it did not mean that the 43rd Army, which had always been suffering, did not want them. If not, it would be a treasure to suppress the army when the 43rd Army was rebuilt in the future.
The two heavy mortar battalions were placed around the air raid shelters not far from the city wall. Once they encountered Japanese heavy artillery and air threats, these not-too-heavy artillery artillerymen could still carry them to avoid them.
However, mountain artillery and field artillery were ineffective and there were no fortifications. Once the location was detected by Japanese reconnaissance planes, it would be a dead end.
Because the depth of Songjiang is so great, where can the mountain artillery and field artillery move? Since they can't get very far by running, they can only resist forcefully.
Use stronger fortifications.
In such a short time, it is naturally impossible to build that kind of permanent reinforced concrete fortifications, but semi-permanent ones should be okay.
There are 48 artillery pieces in 3 mountain artillery battalions and one field artillery battalion, all placed in semi-permanent fortifications made of logs and sandbags as the main materials. The fortifications are not only half-sunk underground, but also camouflaged on the top. No expense was spared in manpower and material resources to build them.
A spire similar to a roof.
That was all to avoid being detected by Japanese planes.
What is more important than disguise is that the fortification itself must be strong enough.
Cut the main material that can be used as roof beams as the top of the fortification, and cover it with one meter of sand and two layers of sandbags. It can basically withstand the bombardment of a 75-caliber mountain gun, even a 150-caliber heavy artillery, as long as it is not hit from the front.
The fortifications protecting the artillery will not be completely destroyed.
In order to avoid the terrible explosion caused by the shell being hit, there will be a small basement with a depth of 3 meters underground near the fortifications. The basement is actually a simple hole. Because of the tight time, it is natural not to care about the appearance.
, dig a hole deep into the ground, support it with wooden pillars removed from the house, and then dig out a sloping slope to the ground to facilitate the gunners to move the shells.
This kind of special fortification for artillery has firing ports with an area of more than 2 square meters on all sides, which basically guarantees the shooting angle of the curved howitzer to project shells to most areas outside Songjiang City.
These were built according to Tang Dao's fortification construction design drawings. From the beginning, Tang Dao had no intention of letting these artillery fire against Japanese artillery. They had only one target, Japanese infantry within five kilometers of the city.
That means, I don't care how you hit me, I'm just an infantryman anyway.
That's because, regardless of the fact that the Liao-made 13th field gun and mountain gun equipped by the 67th Army are basically based on the Krupp 75mm caliber artillery, their range and power are no worse than the Type 41 mountain gun equipped by the Japanese army.
, but as the attacking party, the more mobile and flexible Japanese artillery can move positions at any time. At this time, there is no anti-artillery radar that can calculate the Japanese artillery positions based on ballistics.
If there were advanced wireless equipment, Tang Dao could recruit his own special forces, lurk outside the city, find artillery positions, and remotely report target coordinates to his own artillery.
But unfortunately, there is no such thing. The most long-range communication equipment currently equipped by China and Japan is a heavy field radio.
No matter how awesome Tang Dao is, he can't carry such a big guy around on his back!
Instead of wasting ammunition trying to suppress each other with the Japanese artillery, it would be better to kill and injure the Japanese infantry in large numbers.
The three artillery battalions are located in three directions, which can basically guarantee that at least twelve cannons can kill Japanese infantry in any direction of the four walls.
As a cannon, field artillery is naturally mainly aimed at farther areas, such as armored targets.
In order to ensure that the four artillery battalions can fire on the designated targets in time, Tang Dao even placed the artillery observer's position on the city wall. For this reason, he did not hesitate to spend a lot of manpower to dig out artillery observation posts above the city wall, and even specially buried an artillery observation post for each observation post.
Several telephone lines and several telephones.
Once the telephone lines are cut by artillery fire, not only will the signal corps be responsible for repairs, but uncommon semaphores will also be used.
For this reason, the four artillery battalions borrowed almost all the telescopes of each infantry battalion except the chief officer. They needed to obtain the artillery coordinates as quickly as possible.
Before the arrival of the 30,000 troops of the 67th Army, these were just blueprints and a pile of ruins drawn on paper, but after tens of thousands of people working for five or six hours, they gradually began to take shape.
The civilians may not know much about it, but the officers and soldiers of the 67th Army and the 43rd Army have all experienced wars, so they naturally know how powerful these fortifications are.
Based on this, the Japanese couldn't even think about breaking in without losing tens of thousands of lives. Even if they entered the city, there would be even more brutal street fighting waiting for them.
According to the plan, each regiment, battalion, company, and even squad has its own defensive area. For example, if you conquer the living room of a residential house, there will still be resistance in the bedroom and backyard.
According to Deputy Director Tang of the General Staff Department, every inch of land in Songjiang City will become a battlefield.
Too cruel.
This is the first thought that flashes through the minds of every battalion-level commander who gets their respective defense area planning map.
They had no doubt that in this small town, when the scarred Japanese troops broke through the city wall with joy and broke into it, they would be extremely disappointed to find that what was waiting for them was not the delicious fruits of victory, but the real battle had just begun.
They had just knocked on the door of a large mill.
The large millstone that has begun to be rotated by the officers and soldiers of both sides needs to be ground only with the flesh and blood of the soldiers on both sides...
Ps: It's a little late, because today is the Hubei high school entrance examination. Fengyue just came back after the high school entrance examination. Ahem, I came back with my little girl who just finished the Chinese language test. I hope her next exam will go well.
