Du Yuming was a very cunning general, he carefully studied the topography and water patterns of Shanghai, and he found that although the Japanese army had powerful weapons and firepower, one thing had to be admitted was that mechanized mobile warfare did not work in Shanghai, that is, the Japanese army could use armored vehicles and tanks on the battlefield, but it could not be on a large scale.

Moreover, the Japanese army only has a small area of control so far, so Du Yuming feels that the combat environment at this time is very similar to the First World War, and he thought of a word, trench warfare, a tactic that seems to be about to be forgotten.

Zigzag trenches began to appear on the battlefield (Chinese drama directors are irresponsible, their trenches are all straight), in the trenches, the soldiers can not even see beyond ten meters, but they can provide protection for the soldiers when the enemy strikes the flanks.

In addition, the soldiers found that when the enemy's shells landed in the trenches, his shrapnel did not fly everywhere, but was blocked by the wall. Effectively protected soldiers in other positions.

The trench has two walls, one side faces the enemy, and the other side faces the enemy, respectively called the breast wall and the back wall, the back wall can block the shrapnel behind the trench, and once the enemy occupies the position, then the original back wall can be instantly transformed into a breast wall, Sichuan's money, as long as there is time, they will also pull up the iron wire, pounce on the wooden planks in the trench, there are wooden frames and sandbags on both sides of the trench, Qian Dajun has been stupid, this trench still does this, so much knowledge, how can I not know how to be a teacher.

Thinking that there were not many opportunities to understand the southwest troops, Qian Dajun personally visited the front line, just in time for the Japanese artillery bombardment, in desperation, Qian Dajun followed the staff officer into the shelter hole of the support trench, this hole is deeper than the artillery hole he has seen, it is as deep as two floors, the water in it has been pumped away, and a lot of wooden planks are placed on the ground for cushioning, although it is a little damp, but it does not hinder walking, and there are cement pillars on the pillars in the corners.

In trench warfare, what is fought is the attrition of soldiers, the Japanese planes have no advantage, the tanks have no advantage, and the naval artillery cannot do much damage to this kind of position, so the soldiers can only carry out wave attacks again and again.

But there were so many grenades and shotguns from the Shina soldiers in the trenches of the Devil's Road, and groups of Japanese soldiers finally rushed into the positions of the Shina soldiers, and their shotguns turned the excellent Imperial soldiers into a sieve at once.

What's even more terrifying is a bottle that can breathe fire, a weapon that the Imperial Intelligence Department has never paid attention to, in a narrow trench, with a long tail, and then the soldiers of the Reich become flaming flames, damn the Shina people, can't they have a good fight with the soldiers of the Great Japanese Empire?

Matsui Shigen couldn't sit still anymore, where is this Du Yuming, why is this Du Yuming sacred, why are they playing with the Japanese Empire, what kind of weapons are they using, can easily destroy the empire's tanks, he knows very well that if the empire can thicken the tank, it seems that it can resist, but the waste of the imperial Mitsubishi Heavy Industries will not produce more steel at all, and the engineers of the empire have no other way to make the steel stronger.

Matsui is a very good commander, but in the face of this backward and rogue tactic called General Du Yuming, there is no way at all, and he can only consume soldiers with him, but the people of China have long been prepared, their consumption is obviously smaller than that of the empire, and they have too many people, so if it goes on, the soldiers of the empire will be consumed.

The losses of the troops were too great, and after this guy named Du Yuming arrived on the battlefield, Luo Dian and Yuepu generation under his offensive, at least let the empire lose more than 40,000 imperial soldiers, and the combat effectiveness of many divisions and regiments was sharply reduced.

Chiang Kai-shek was very shocked by Du Yuming's achievements on the front, and the third Kuomintang lieutenant general and Whampoa officer with the rank of general was produced, which was Du Yuming, and Du Yuming also became famous in the Songhu battlefield, and was called a cunning little mouse by the Japanese base camp, and they would never have imagined that this hateful rat would cause more damage to them in the near future.

Du Yuming's tactics were surprisingly successful, causing huge losses to the Japanese army, and in desperation, Matsui Shigen also had to shrink his troops to several battlefields, and more than 800,000 Kuomintang troops took advantage of the victory to pursue and control the Japanese army in an extremely narrow area. ”

"The Japanese army has once again increased its forces in Shanghai, including one division and one brigade from the northern battlefield, and two divisions and regiments in the mainland and Korea, and if these troops are all on the battlefield, the Japanese army will have almost 400,000 troops." Dai Li stood beside Chiang Kai-shek and told Chiang Kai-shek the latest situation.

Hearing the information, Chiang Kai-shek was very happy and said to the people around him, "Everyone? What do I say, you all think that our strategic goal has been achieved, so what are the troops that Japan is transferring today? You are all timid, and now we have truly achieved our goal of mobilizing the Japanese forces. ”

"Yes, the Japanese army finally moved with us, and our strategic goal was achieved." Lin Wei said excitedly.

Unlike others, Yang Yongtai is always floating outside, and his expression is always melancholy, which is difficult to understand. "Chairman of the Committee, from the intelligence of the Military Intelligence Bureau, Japan is preparing to land in the northern area of Hangzhou on a large scale, and our troops are not enough, so we can't prevent it."

"No, aren't the Eighth Army and the Fifteenth Army there?" Chiang Kai-shek asked puzzled.

"Principal, we are working with the devils with real knives and guns, how can you let them fight the devils with Hanyang and bird guns, their equipment is not as good as the Red Party!" Bai Chongxi said on the side.

Bai Chongxi wanted to say to Chiang Kai-shek, "Chairman, let's retreat, the Japanese army's aid force has not yet come, our war is going so smoothly, the little devils are afraid of us, we will take this opportunity to retreat quickly, withdraw to the Wufu line, according to the chief of staff's plan, continue to fight with the Japanese army, and also give the troops a chance to rest and recuperate." But Bai Chongxi knew that as long as he opened this mouth, he would be scolded 100%.

Bai Chongxi didn't speak, it didn't mean that Chen Cheng could bear it, but the people who died were all the elite soldiers of the Central Army and their civil engineering department and the southwest department, which were all Chiang Kai-shek's descendants, so he said to Chiang Kai-shek, "Chairman, it's time for us to give up Shanghai, our strength has reached the limit, there are 150,000 wounded soldiers alone, and if we don't withdraw, we will soon run out of additional troops." ”

At this time, Chiang Kai-shek was waiting for the results of international mediation, but Chen Cheng gave him such a sentence, and the angry Chiang Kai-shek almost slapped the table, "Resignation, we must hold on, our foreign minister is talking to the powers, we can't give up international support." ”

Chen Cheng's face was blue for a while, white for a while, and he finally understood that Liu Yuan was running so fast for what he was doing, Chiang Kai-shek was stubborn, how did he be blinded by lard at that time, and he was consistent with Chiang Kai-shek in thought, this Shanghai is a big hole.

After the meeting, Chen Cheng and the commanders of the Third Theater talked about military affairs together, Gu Zhutong almost died of anger after listening to Chiang Kai-shek's words, and the staff officers left behind in the Southwest Special Region smoked vigorously, since Liu Yuan left, their words became very few, but the occasional conversation showed their extreme disdain for Chiang Kai-shek's methods.

Looking at the depressed atmosphere in the headquarters, Chen Cheng walked to the edge of the map and looked at it for a long time, clicked on the map, and a crazy plan appeared in his mind.
