On March 9, the Japanese army has broken through the eleven lines of defense set up by the Chinese army in a row, and the battle line has been infinitely close to Zhangjiakou City, and the offensive for more than ten consecutive days has caused huge casualties to both the offensive and defensive sides, for which the North China Front has increased its troops in Zhangjiakou twice in a week, and now the number of Japanese troops gathered in the periphery of Zhangjiakou has reached more than 90,000 people, except for the Fifth Division, the 38th Division and the Third Chariot Division. The 10th and 26th Divisions, the absolute main forces of the North China Front, were also transferred to the Zhangjiakou front.

Due to the large casualties of the troops, Tada Jun directly ordered Okamura Ninji to take over the command of the front line and command the more than 90,000 troops on the outskirts of Zhangjiakou nearby. Okamura Ninji was also a master, under his command the Japanese suffered much fewer casualties and broke through the positions of the Chinese army much faster.

Okamura Ninji's command quickly convinced the senior Japanese officers on the Zhangjiakou front, and unlike their old and backward tactics, Okamura Ninji attacked in a variety of ways, and the offensive methods were extremely ruthless. Heavy artillery, combat vehicles, and airplanes were used to the fullest by Okamura Ninji, and the maximum combat effectiveness was exerted. The use of earthwork greatly reduced the casualty rate of the troops, and tactics such as incendiary bombs and water diversion and irrigation emerged one after another, causing huge casualties on the defenders.

Today, this line of defense is the last line of defense set up by the Chinese army outside the city of Zhangjiakou, and as long as this line of defense is broken, it will be much easier to take Zhangjiakou. So all the front-line commanders today are excited, and they believe that Lieutenant General Gangmura will not let them down.

"Order: The heavy artillery brigade will concentrate all its heavy artillery on the main pillbox defended by the China, and all the chariots will be concentrated and used, and the western slope where the China's defense is weakest will be made with all its might. The infantry did not follow, let the sappers go to demine. Okamura Ninji decisively gave the battle order.

"Hail"

Zhangjiakou Underground Headquarters.

"Lao Xu, the little devil is really a real soldier coming to the city, Zhangjiakou City will be broken in three days at most, let's prepare for retreat as soon as possible, the commander will let the second and third divisions meet us in the area of Zhangbei Shangyi."

"Lao He, don't worry, this old devil in Gangcun is really terrible, in a week, we have broken through more than half of the fortifications we have built for more than three months, and also let our two divisions lose more than 10,000 people, this old boy is the most powerful Japanese commander I have ever seen, we must fight with Gangcun, otherwise we will suffer losses in the future." Don't worry, even if they occupy our last line of defense, it's nothing, if Zhangjiakou City relies on those dozen true and false defense lines to block the Japanese army, then these dogs are too underestimate the commander, the defense line on the periphery of Zhangjiakou is just an appetizer, the real killing move is still in the city, although the casualties in the street battle are uncontrollable, but this is also our best chance to destroy the Japanese army. Then Xu Shiyou said: "Lao He, here is a defense plan for the inner city of Zhangjiakou, which is a big dish specially prepared by the commander for the little devil, now you and Political Commissar Zhang will arrange it, today I will go to the front line to command the troops, and I will have a trick with the old boy in Gangcun."

He Guangyu knew that he couldn't persuade Xu Shiyou, and if he persuaded again, it would make this old boy anxious with him, so he said: "I have no objection to you going to the front line, but you have to bring the special combat team, if something happens to you, we must be transferred to the old forest in the northeast by the commander." ”

The most cutting-edge headquarters is located in the city gate hole of the south gate of Zhangjiakou, the building above this city gate building has been blown up, and there is only one city gate hole that has been reinforced with reinforced concrete. The wall on this gate hole is more than five meters thick, so even the largest aerial bomb used by the Japanese army cannot destroy this city gate hole, so the first brigade set up its headquarters here. …,

When Xu Shiyou came in, Shangguan Qing was discussing with Yang Shilang, Li Debiao and others how to defend. They were all shocked to see Xu Shiyou coming in person, especially Shangguan Qing said a little worriedly: "Commander, why are you here, it's not peaceful here, if there is anything, you can just make a phone call."

", Lao Tzu is not a landlord and old wealth, he is afraid of death and is still a fart soldier, don't worry, the little devil wants to eat Lao Tzu and lacks a good pair of teeth, I am here to press the formation for you, you command you, I look at me, we don't interfere with each other." After speaking, Xu Shiyou directly crossed the huge terrain sand table, walked to the high-powered telescope placed at the observation port, and looked in the direction of the battlefield.

At this time, the Japanese army had already begun to attack, but this time the Japanese army's tactics had changed again, this time the Japanese army completely abandoned the traditional tactics of the past, and instead adopted the tactics of fully mechanized troops used by Germany in the European war. Although the Chinese army had complete fortifications, there were too few artillery pieces that could be used and were a threat to the Japanese tank units.

Although in order to deal with the Iron King Eight of the Third Division of the Japanese Tank Division, Han Yunhua deliberately mobilized more than 100 unconscionable guns from other units to the Sixth Field Division, but the range of the unconscionable cannon was too close, and if you wanted to defeat the Japanese chariot troops, you had to put the unconscionable cannon in the air-raid shelter, wait for the Japanese chariot to come up, and then pull it out and fire, and the Japanese field heavy artillery not only had a long range, but also was powerful enough, Therefore, often the conscienceless artillery of the Sixth Field Division was attacked early by the Japanese field heavy artillery brigade and aviation regiment as soon as it began to shoot, so there are only a dozen of the more than 100 conscienceless guns left, in order to reduce the casualties of the artillery and save the only dozen or so artillery, Xu Shiyou directly transferred the remaining conscienceless artillery back to the city.

However, this did not mean that the Sixth Field Division did not have a way to deal with the Japanese tank troops, watching the Japanese tank units continue to move forward, the air in the entire headquarters froze, and all the people looked nervously at the direction of the battlefield.

"Brigade commander, the troops on the front line reported that the Japanese tanks had entered our predetermined position, and the battalion commander asked if it was possible to release the water?"

"Release the water, order them to release the water immediately," Shangguan Qing ordered loudly.

After finishing speaking, Shangguan Qing walked quickly to Xu Shiyou and said, "Division commander, since we are seriously lacking artillery to deal with Japanese tanks, this time we use unconventional tactics to deal with the Japanese tanks. Without waiting for Xu Shiyou to ask, Shangguan Qing explained: "Unconventional tactics are what you often call wild roads, we took advantage of the night a few days ago to let the troops turn over all the soil in front of this defense line, the soft soil layer is about one meter and a half thick, ordinary people walk up and it's nothing, even if the chariot is pressed up, it's a little difficult to travel, but as long as we inject a lot of water into this area, then this place will immediately become a soft swamp, let alone a chariot, Even people can't go here. Our first brigade is going to paralyze all the tanks of the devil this time, and I see how the old devil in Gangcun, who has lost so many tanks, can fight. ”

Xu Shiyou was overjoyed, Shangguan Qing is indeed a talent, a few days ago Shangguan Qing asked him to build a small reservoir behind this discovery, he was still a little reluctant, but out of consistent trust, he still ordered the engineering regiment to build a reservoir that is not very big, now it seems that this reservoir is used to thin mud, and he knew that this reservoir would be built a little bigger.

"Haha, you kid really has a lot of ideas, no wonder the commander appreciates you so much, the old devil in Gangcun doesn't have many chariots in his hands now, there are only more than 250 chariots in the entire 3rd Division of Zhenche, but during this time, more than 170 chariots were lost in our hands, counting the more than 50 vehicles on the front position, the Japanese army now has no hidden chariot troops. As long as we eliminate these fifty or sixty devils' chariots, then we will be equivalent to completely annihilating the main force of the 3rd Division of Japanese Tanks. You kid is really a fucking freak, hehehehe" Xu Shiyou's mood at this time was not only excited but also excited, he didn't expect that Shangguan Qing still had a way to deal with the Japanese tank troops. …,

In fact, the Japanese tank unit found an anomaly as soon as they drove into this soft place, but they thought that the Chinese army had planted heavy mines here, so in addition to pears this place with artillery, more than 100 devil sappers were dispatched to clear the mines.

In order to conceal his true intentions, Shangguan Qing really planted a large number of mines here, and there were even three giant mines among them. The Japanese army really made a lot of gains in this action, as the mines were hit, the sound of explosions came and went, and the Japanese army's engineering units were also very good, and the business was not only skilled, but in just ten minutes, more than 130 large and small mines were raised, of course, the Japanese army's sappers also suffered a lot of losses, and the snipers in the Chinese army were not vegetarians, and after a while, they sniped more than 30 Japanese sappers.

However, compared to the chariot, the sapper was also a consumable, so despite the large losses of the sapper, Okamura did not order the sappers to retreat, but transferred an infantry brigade to suppress the Chinese defenders. With this infantry brigade, the offensive of the Chinese defenders was quickly suppressed, and in just over half an hour, the Japanese engineering units cleared all the mines in all areas within a radius of 100 meters.

After a few turns, the Japanese chariot troops finally approached within 300 meters of the defenders' position, and when the Japanese chariot troops were preparing to continue advancing, the scene in front of them frightened the Japanese charioteers, only to see a torrent rushing quickly towards this soft land along the gentle slope of the low height, and the huge waves soon turned the soft ground in front of it into a muddy swamp, and the Japanese chariots continued to sink and ......sink in this rotten place.
