As time passed, the fighting in Shanghai became more and more intense, and the relatively superior Nationalist troops launched an all-out attack on the enemy in the downtown area of Shanghai, and at the same time dispatched the air force to bomb the Japanese Marine Corps headquarters, Huishan Wharf, and surface ships. In addition to the 2 elite divisions, the Nationalist Army also had 2 heavy artillery regiments equipped with German artillery, namely the 10th Artillery Regiment and the 14th Artillery Regiment, plus tanks and air forces to assist in the battle.

The Japanese army in Shanghai only had more than 3,000 marines, and then urgently mobilized retired soldiers from the Japanese merchant groups, a total of only 4,000 people, but the Japanese army relied on strong fortifications to resist stubbornly, so that the national army troops have not been able to complete a major breakthrough. Although the battle in Shanghai has fallen into a stalemate, when the news reached Chongqing, many people still felt that the Japanese army was not very difficult to deal with, of course, among these people, Tang Cheng was not included.

"Don't be too happy, the Japanese army currently has a limited number of troops in Shanghai and lacks heavy weapons and equipment. Although the current situation seems to be unfavorable to the Japanese army, you should not forget that the Nationalist troops in Shanghai will not be able to move. The Japanese mainland is not far from Shanghai, and once the Japanese navy enters the war, their troops can rush from the mainland to Shanghai to land and participate in the war by sea. Shanghai is a coastal city, which makes it very convenient for Japanese naval ships to provide long-range fire support to ground forces in an offshore position. ”

When Tang Cheng spoke, there was a circle of instructors and trainees from the training camp sitting beside him, and during this time after dinner every day, Tang Cheng always liked to chat with the students here in Tutai. Today's topic is the battle in Shanghai, and when everyone is happy, Tang Cheng has the opposite attitude. "The caliber of the main guns of large ships of the Navy is more than 400 millimeters, and this kind of naval artillery shells can destroy a three-story building with a single shot, and the killing range of open ground can even reach 50 meters. In other words, if such a shell falls in the position, it is likely that the strength of a platoon will be gone in an instant. ”

You can also see so-called foreign warships here in Chongqing, but they are just ordinary river gunboats, and they cannot be compared with real warships sailing in the open sea. When Tang Cheng said that such a single shell could destroy a three-story building, the training instructors and students present were all shocked. "If you are in the center of an explosion in a naval gun, death can be a relief, and the worst of all is the soldiers who are injured by the explosion and will suffer for days before they die of organ failure."

What Tang Cheng said at the moment was not alarmist, and his worries finally became a reality over time. The 87th Division of the Nationalist Army occupied Hujiang University, and the 88th Division occupied Wuzhou Cemetery, Baoshan Bridge, Bazi Bridge and other key points, and then the independent 20th Brigade arrived in Shanghai to take over from Sun Yuanliang's division of the 88th Division to defend Shanghai Patriotic Girls' School and Zhizhi University, and took on the task of attacking Hongkou Park and Jiangwan Road Japanese headquarters. Seeing that the war was unfavorable, Emperor Hirohito of Japan ordered Senior General Matsui Ishine to send a military commander to Shanghai to command the 3rd Division, the 11th Division, and other troops directly under the army to attack Shanghai, planning to further expand the war of aggression against China.

On August 21, a huge fleet headed by the Japanese battleships Nagato and Mutsu transported about 10,000 people from Japan to the Saddle Islands, carrying about 10,000 people from the vanguard of the Japanese Shanghai Dispatch Army. On the night of the 22nd, the Japanese army changed into light cruisers and destroyers in the Ma'an Islands, and sailed into the area of Chuansha Town and Wusongkou respectively, and at dawn on August 23, the vanguard of the reinforcements of two divisions led by Matsui Ishine landed in Shishilin, Chuanshakou, Zhanghuabang, etc. under the cover of sea and air firepower.

At dawn on August 31, the Japanese army attacked Wusong with more than 30 planes and naval guns and forcibly landed; Another part of the Japanese army landed at the city ferry terminal. On September 1, more than 1,000 Japanese troops besieged the Lion Forest Fort. From 2 to 5 September, with the support of warships, aircraft, and tanks, the Japanese launched a fierce attack on the central part of Xiachu, the 98th Division of China, which was defending Yuepu and Baoshan, with the support of warships, aircraft, and tanks.

On September 9, the Japanese army launched a powerful offensive against the Chinese army along the military road, Songhu Highway and the line of Yuepu and Luodian, and our army launched a desperate struggle with the enemy, on September 11, the right flank position of the 15th Group Army was broken through, and the troops were seriously reduced, so they gradually retreated to the pre-built positions of Shixianggongmiao and Liuhe lines south of Luodian, and the 9th Group Army also moved to the pre-built positions of the North Station, Jiangwan, Miaoxing, and the line on the right bank of Fuzaobang, forming a confrontation with the Japanese army.

The Japanese army gradually seized the initiative on the battlefield, and the Japanese top level decided to shift the main operational direction of the invasion of China from North China to Shanghai, and demanded that the process of the Shanghai campaign be accelerated, and the decision to increase troops was made again. The 9th, 13th, and 101st divisions of the North China Front Army were transferred to the Shanghai Dispatch Army, and in addition, the infantry brigade, the Shigeto detachment, the 1st reserve infantry regiment, and the 1st Brigade of the puppet Jing'an Army, the puppet Li Chunshan Brigade, and the puppet Yuzhishan Brigade were also transferred from Taiwan.

The battle has reached this level, and even Zhang Jianghe, who is in Chongqing, can see that the momentum is not good. Although the Nationalist Army subsequently followed with a continuous increase in troops to Shanghai, the Nationalist Army had now switched from the previous offensive to a passive defense, and most of the troops that followed up to reinforce Shanghai were second- and third-line troops. The team formed by the intelligence department had already been put into the Shanghai battlefield, but the results achieved by this unit were not as the Lord in Nanjing wanted to see, and when Zhang Jianghe got the news, more than half of the troops had already suffered casualties.

"Uncle, I told you before that the intelligence department is not good at frontal combat, especially if the opponent is still the regular army." Looking at Zhang Jianghe's ugly face, what Tang Cheng wanted to say was not actually finished, but the subtext had already been revealed. It would be strange to be able to fight an offensive and defensive battle against the regular troops, and send a group of people who have long since left the army! I really don't know what the one at the Nanjing headquarters thinks!

"I also know that this thing sounds unreliable, but the previous war was too smooth, although it failed to drive all the Japanese troops in Shanghai into the sea, but it was also very good. I thought in my heart that this time I should have hurt the Japanese, and maybe those brothers would be able to return home with a big victory, but I didn't expect that in just a few days, the situation would all change. Zhang Jianghe's voice was low, and there was a faint moisture in his eyes, the intelligence department had organized thousands of people to enter the Shanghai war zone this time.

Tang Cheng didn't have anything in his heart, but the intelligence department made a bloody investment this time, and in the end he made a loss-making deal, no matter who he was, he would feel uncomfortable. "Uncle, do you want to send a telegram to Nanjing to comfort the headquarters?" Tang Cheng's words were not deliberately joking at Zhang Jianghe, but seeing that Zhang Jianghe was depressed, Tang Cheng wanted to deliberately change the topic to distract Zhang Jianghe. Zhang Jianghe naturally didn't blame Tang Cheng, just like Tang Cheng was familiar with him, Zhang Jianghe also knew Tang Cheng's character.

"Stop talking nonsense, how did the last thing you told me go?" Zhang Jianghe, who was anxious in his heart, raised his hand and knocked Tang Cheng with a chestnut blow, and found that the anger in his heart had dissipated a lot, so he told Tang Cheng about a very important thing. The matter mentioned by Zhang Jianghe at this moment, even in the investigation team, few people knew about it, and if this matter did not need the assistance of Chongqing Station, Tang Cheng originally planned not to even tell Zhang Jianghe.

"Uncle, I remember that your old man is not an impatient person! It's only been half a month, where will it be effective so quickly! Tang Cheng grinned a little helplessly, since he was injured and needed to recuperate and was forcibly confined in the backyard of the barracks by Zhang Jianghe, Tang Cheng was pondering and secretly advancing a plan, Zhang Jianghe only knew about it half a month ago. Tang Cheng, who refused to confide in his heart, was stared at by Zhang Jianghe without blinking for a while, and then took out a list and handed it to Zhang Jianghe with an impatient face.

"Uncle, I can tell you, this plan has just begun, so there are not many people on this list. You have to be patient with this, as long as you follow the plan, it will only take half a year, and this plan will at least double your intelligence channels. Tang Cheng handed over the list and chattered in Zhang Jianghe's ear, but Zhang Jianghe, who was concentrating on looking through the list, stretched out his hand and pushed it away with an impatient face.

Zhang Jianghe, who had looked through the list, looked a little wooden with a wooden expression, and after pondering for a while, Zhang Jianghe spoke. "This plan is good, but you can't continue to participate, if you continue to participate, it won't be clear in the future!" Zhang Jianghe didn't break the words, he knew that Tang Cheng was very smart and should be able to understand what he was saying, especially the last few words of his own, which had already indicated what he wanted to express.

Zhang Jianghe guessed correctly, Tang Cheng just pouted when he heard this, but he didn't say anything. Perhaps because he felt that it was a little unauthentic for him to forcibly take away this plan, Zhang Jianghe then said warmly, "Xiao Wu, you are very smart, but the one in Nanjing is not stupid." That person's temperament is difficult to fathom, and he especially can't tolerate the people below being deceived, and this plan involves such light that it can't be hidden. ”

Zhang Jianghe patiently explained, but Tang Cheng didn't appreciate it, "Uncle, I didn't say anything, what are you telling me so much?" Don't worry, you know what you mean, and I don't want to do anything bad in private. Anyway, I have a lot of things to do these days, and the things at hand, if I can have one less, I don't care, I can just rest a little more. ”
