Yuhuatai, Meigang.

Zhang Lingfu led the 305th Regiment to defend the Hedingqiao line. Although he was seriously injured, he refused to retreat. He won enough time to rebuild fortifications in the rear fortifications for the friendly troops. Although he was repeatedly harassed by Japanese bombers, the whole process was intermittent, by noon, the defense fortifications of the 19th Brigade were basically completed.

Xu Shijiu and Qiu Weida's tactical ideas were exactly the same. They both chose to build the fortifications in the center of the top platform on the mountain, rather than the fortifications on the edges connecting the platform and the hillside.

Student soldier Shu Tongwen also participated in the repair of fortifications. He couldn't help but ask Xu Shijiu until the fortifications were completed: "Captain, build the fortifications in the center of the top platform on the mountain. You can't see it below the platform. Can't Xiaojiu climb up the hillside calmly? If you build the fortifications on the edges, can't you better suppress the Japanese army?"

Xu Shijiu sighed and said, "It is indeed better to build the fortifications on the edges of the ridges. But everything has advantages and disadvantages. If your shooting range is wider, it means that the enemy's firepower will more easily threaten you. If we have the advantage in firepower, that's nothing, but if our firepower is at a disadvantage, it will be troublesome."

Shu Tongwen was able to understand it at once, and suddenly realized: "I understand that if the fortifications are built on the edge of the fortifications, the Japanese grenade launcher, flat-fire cannons, and even curved cannons can achieve firepower coverage. Faced with the artillery firepower of the Japanese army, which was absolutely superior to the Japanese army, the simple fortifications built in hasty can't bear the hasty.

But it is different to build the fortifications in the middle of the platform. Due to the obstruction of the mountain, the Japanese flat-fire cannons were no longer available. In addition, the Japanese observation balloons were not as high as the top of the mountain. After losing the guidance of artillery observers, the field cannons could only carry out untargeted large-scale artillery bombardment, which would greatly reduce the threat.”

For Xu Shijiu, who has systematically studied artillery courses, these are just common sense, but for Shu Tongwen, who has never been exposed to artillery courses, this is a completely unfamiliar field of knowledge. Shu Tongwen was able to summarize such valuable experiences based on his own observations, and his understanding can be said to be very high.

Xu Shijiu patted Shu Tongwen's head and sighed: "Awen, if possible, I really want to send you to study in pastry. If you can study hard at pastry for three years, you will definitely become an excellent officer after graduation. If China wants to defeat the Japanese, it is impossible to do without an outstanding young man like you."

Shu Tongwen retorted: "Captain, you don't seem to be too old, right?"

Xu Shijiu smiled and said no, although he was not old, his military experience was quite rich. The key is that he had been deeply labeled as "the remnant of the 19th Route Army". The rank of colonel and the battalion-level chief officer were already at the limit. It was impossible for him to have greater development in the national army camp.

Shu Tongwen's attention soon returned to the fortifications and asked again: "The captain has another question. Why should the fortifications be built into a curved 'zhi' shape, but not several straight lines?"

Xu Shijiu said: "This is the same as the formation of the word "zhi" in an open marching. If you walk in a straight line, the casualties will not be very large when being fired by enemy planes. If you walk in a formation of the word "zhi" you can minimize casualties. By the same token, making fortifications into the shape of the "zhi" can also minimize the threat of dive strafing by Japanese planes."

"So that's how it is." Shu Tongwen nodded, pointed to the deep holes dug in the trench and asked, "What about these small holes? Why are they digging them out for?"

Xu Shijiu explained: "This is called a lightning hole, which is specially designed to defend against the grenades of the little Japanese man. The melon grenade of the little Japanese man exploded forty-eight pieces, which is extremely lethal. Therefore, a special lightning hole must be dug. As soon as the grenades of the little Japanese man were thrown over, it kicked into the lightning trough, so that the fragments produced by the explosion will be no threat."

After a pause, Xu Shijiu continued: "But this lightning hole can only be used to deal with new recruits who are not in Japan. If you meet Japanese veterans, they will usually delay the fuse after opening the fuse for a few seconds before throwing it over. The grenades thrown in this way usually explode in the air, and their lethality is more powerful than explosions on the ground."

Shu Tongwen's face changed slightly and she said indignantly: "We can also pull the grenade fuse and then delay it for a few seconds to throw it out."

"I'm afraid it won't work." Xu Shijiu shook his head gently, "Except for the original imported grenades in Germany, whether they are made in Jinling, Gongxian or Hanyang, the quality is uneven, and the extension of the fuse is irregular. If you pull the fuse for a few seconds and then throw it, maybe you will explode without waiting for you to throw it out."

"Ah?" Shu Tongwen was stunned and said frustrated, "After all, our industrial foundation is too weak, we cannot build aircraft and cannons, nor can we build reliable grenades."

Xu Shijiu said: "That's why I strongly oppose that you students going to the battlefield. It is really not easy for the country to train a college student like you. Compared with fighting with the Japanese invaders, there are more important things waiting for you to do, such as developing the industry of the motherland and building cannons, aircraft and even warships as soon as possible."

"How easy is it to build airplanes and cannons?" Although Shu Tongwen's military camp has not been long, he has been wandering on the brink of life and death several times. Compared to the scholarly spirit when he was on campus, he has become more mature in thinking about the problem and sighed, "Not to mention airplanes and cannons and warships, even the National Government of Steel cannot be refined."

Xu Shijiu was silent. When it comes to major issues related to national strategy, he was not very familiar with it.

Shu Tongwen's words were opened but he couldn't stop it. He said angrily: "I have been confused that the little Japanese is just a tiny island country, with a population and resources far from comparable to China. But why did Japanese Japanese develop a powerful heavy industry, and aircraft, cannons and tanks can be produced in large quantities, and even the most advanced battleships in the world. However, the heavy industry in our China has always been zero. Not to mention aircraft, cannons, warships, tanks, and even steel used to make guns, ammunition and drugs need to be imported from abroad. Why is this happening? Why?

During the Qing Dynasty, we were bullied. During the warlords' melee, we were bullied. Now that the Republic of China has basically completed the reunification, why are we bullied? Captain, I really can't understand what happened to China? Why did the Chinese nation, which was once powerful for a while, become a fish that everyone bullies? "

Shu Tongwen couldn't figure it out, and Xu Shijiu naturally couldn't figure it out even more. He immediately patted Shu Tongwen on the shoulder and said, "These principles of saving the country and the people are exploring by you scholars. When did you understand this? Don't forget to tell me, I want to know too."

After saying that, Xu Shijiu turned around and left.

Shu Tongwen fell into a long and deep thought, and even didn't know when Xu Shijiu left. Shu Tongwen's confusion was actually the common confusion of all the knowledgeable, ideal and aspiring young people in modern China. Shu Tongwen actually came into contact with various theories when he was studying at Peking University, but he had never thought about it seriously before.

At noon on the 9th, Zhang Lingfu's 306th Regiment was ordered to retreat to the Collector Lane and Yangzhuang line due to too much casualties.

The 36th Japanese Infantry Regiment tried to break through the 306th Regiment's defense line in one fell swoop when the 306th Regiment was not yet stable, but was defeated by the 306th Regiment's decisive counterattack several times. The positions changed hands repeatedly, and the war was extremely stalemate. When the captain of the 36th Regiment's 36th Regiment's corps was too difficult to chew, Jiro Wakisaka, saw that the bone of the 306th Regiment was too difficult to chew, he turned his attention to Yuhuatai on the flank of the 306th Regiment's position.

The Shanghai-submitted the two Japanese groups and the 10th Army were secretly competing, wanting to capture Nanjing before the other side. The divisions within the two Japanese groups were also secretly competing. Similarly, the infantry regiments within the divisions were also competing, wanting to enter Nanjing Wucheng before the brothers.

The 9th Division has four infantry regiments under its jurisdiction, namely the 7th, 19th, 35th and 36th regiments.

The 7th United Team Captain Isaichio and the 19th United Team Captain Izumi Hidezo were classmates of Lu Shi's 23rd period, the 35th United Team Captain Fujimoto Yoshi and the 36th United Team Captain Izujiro were also classmates of Lu Shi's 19th period. The four squadron captains were naturally divided into two camps and were also competing with each other in secret.

Because the 9th Division did not fight well in the Battle of Shanghai, the casualties were the largest among the divisions participating in the battle. The division commander Yoshisuke was under great pressure. He was so anxious to fight a turnaround in Nanjing, so he consciously promoted the fire in secret, which led to a "hard" situation where the captains of the four infantry regiments competed for the first time.

The four infantry regiments of the 9th Division, the fastest one was the 19th Infantry Regiment of Hokage, who had already hit outside Guanghua Gate. This is not to say how strong the combat effectiveness of the 19th Infantry Regiment is, nor to be because of how superb the command attainment of Hokage, but because the 19th Infantry Regiment of Hokage is good enough.

The 51st Division retreated from Chunhua Town, and the 9th Division of the Japanese army followed and chased, but was stubbornly blocked by Zhang Lingfu's 306th Regiment at Heding Bridge. Several fierce attacks were defeated. Yoshizuru Ryosuke ordered people to attack from the flanks. The detour of the regiment happened to hit the gap between the 88th Division and the 51st Division.

The 88th Division and the 51st Division received orders to retreat almost at the same time, but the 88th Division's defense zone was outside the city wall. After receiving the order, they quickly retreated into the city. However, the 51st Division's defense zone was far away in Chunhua Town. It took time to replace the 88th Division's defense zone. It was this time difference that made people see the regiment taking advantage of a loophole and rushed outside Guanghua Gate.

Seeing that the United Team had already hit outside the Gwanghwa Gate, how could Jiro Fukisaka not be anxious?
