On the 28th, the Japanese army, which had been thwarted and heavily damaged, withdrew to the concession to rest. At the same time, under the mediation of ministers from various countries, the 19th Route Army and the Japanese army reached an agreement to temporarily suspend fighting.

However, from the 29th onwards, there were still frequent incidents of firing between Chinese and Japanese soldiers at the main defensive streets, road sections, and houses outside the concession.

It was not until 4 February that the first batch of Japanese reinforcements of more than 5,000 marines arrived in Shanghai, and Shiozawa, who had recovered some of his spirits, once again ordered the final blow.

Because he really didn't want to defeat Japan in such a way, after all, before he came to Shanghai, he boasted of Haikou and occupied Shanghai in three days.

But when I thought that if I was defeated and returned to China, I would not be able to get rid of the shadow of losing to the squadron in this life.

At this time, the total strength of the Japanese army had reached 13,000 men, which was much more than the 78th Division of the Chinese defenders. In addition, the heavy equipment of the Japanese army is obviously dozens of times that of the 78th Division. Shiozawa thinks it's time for him to fight back.

He also sent planes to bomb the Wusong fortress again, and expanded the war to the Jiangwan area.

As a result of this time the Japanese army sent more aircraft, warships and artillery fleets. The losses of the 19th Route Army were heavy, with more than 1,000 casualties in just one day of fighting.

Fortunately, the 78th Division had the strong support of people from all walks of life in Shanghai, and the morale of the army was stable, and the officers and men were able to hold all fronts with their lives.

This time, he took destroyers as the guide, and various minesweepers and anti-submarine boats as escorts, first swept the rope to see if there were submarines lurking in the theater before attacking.

At the same time, because it was found that the 19th Central Army had enough ammunition and food, the Japanese army did not launch a large group charge, but used small troops as bait to attract the firepower of the Chinese defenders.

When all the firing points are clearly detected, they are reported to the artillery team or air force in the rear, and finally the artillery and air force carry out carpet bombing, and then the army carries out the final attack.

Not to mention that the Japanese army came down with these axes, the Chinese defenders really couldn't hold on. Due to the destruction of the Huaxing Aviation Military Academy, China has no air counterattack capability at all in Shanghai. So the entire battlefield was controlled by the Japanese army.

In order to support the 78th Division of the 19th Route Army in the War of Resistance, the citizens of Shanghai donated generously, and a large number of enthusiastic young people volunteered to form an anti-Japanese vanguard to assist the 78th Division in defending the city.

The various forces in Shanghai also contributed to help the defenders build fortifications and carry supplies.

Among these active anti-Japanese forces in Shanghai, there are two of the most outstanding, one is Wang Yaqiao and the other is Li Tie.

Among the two, Wang Yaqiao has the most fame, and even Li Tie, who has contributed the most, has made him overshadow the limelight.

It turned out that after Wang Yaqiao came to Shanghai, he not only ran in many ways to find allies for the 78th Division. He personally led the Axe Gang to enter the concession many times to destroy Japanese warehouses and attack naval ships.

Assassination of Japanese generals. Sneak attack on a Japanese patrol. Because of its swift and concealed movements, the armistice between China and Japan on 29 January and the resumption of the war on 4 February took just one week.

Wang Yaqiao's Axe Gang killed and wounded hundreds of Japanese soldiers. More than a dozen lieutenants were assassinated, and three adjutants died under Wang Yaqiao's assassination.

The Japanese side, which had suffered such a loss, was very angry, and the Japanese ambassador sent a note to the Nationalist Government that Wang Yaqiao must be arrested and brought to justice.

The Shanghai Municipal Government had no choice but to consult with Wang Yaqiao, and finally Wang Yaqiao agreed to live in seclusion behind the scenes. No longer personally go out to pay the Japanese.

Li Tie's Huaxing Company contributed the most, a large number of cotton clothes and quilts, including helmets and leather boots, were continuously sent to the hands of the 78th Division, and countless ammunition and guns were also sent to the front line.

From 28 January to 4 February, more than 7,000 soldiers of the 78th Division had almost every man with two sets of cotton clothes and quilts, two rifles, several hundred rounds of ammunition, and dozens of grenades.

In addition, Li Tie secretly sent hundreds of mortars and dozens of anti-aircraft machine guns from the Shenyang Arsenal. It's a pity that the 78th Division is just a miscellaneous army, and few people will use these heavy weapons at all.

Coupled with the fact that time is pressing, there is no time to train newcomers either. As a result, the use of these heavy weapons was not very efficient.

With the 4th of February, the Japanese army resumed its large-scale offensive. The Shanghai army and civilians began to fight for every inch of land with the Japanese army.

However, although the Shanghai army and civilians were united, the gap between the enemy and the enemy was too great, especially the scarcity of well-trained soldiers.

In addition, the firepower was not at the same level, and the military and civilian casualties in Shanghai were very large, and almost every time they relied on human lives to regain their positions.

In fact, the casualties of the Japanese army were not small, but under the desperate command of the almost crazy Shiozawa Yuki, the Japanese army attacked regardless of casualties, and the advantages of heavy weapons became more and more obvious.

The Japanese army slowly led the first line of defense of the Chinese defenders, and saw that the 78th Division was about to be unable to withstand it.

At this time, the 60th and 61st Divisions of the 19th Route Army near Nanjing rushed to the battlefield, and the balance of war was tilted in favor of the squadron again.

Two full-strength divisions of the 19th Route Army, totaling more than 20,000 people, arrived in Shanghai, making the defenders of Shanghai surpass the Japanese army again. And the two divisions that had just arrived in Shanghai were immediately fully armed by Li Tie.

The two divisions that had just arrived on the battlefield immediately entered the battle, because of the entry of the new forces into the battle, the Japanese army, which had long been exhausted, could only take the initiative to retreat and return to the concession again, and at the same time once again asked for more troops from home.

At this time, Shiozawa Yuki had completely given up the idea of counterattacking. The two sides again began a standoff outside the Shanghai Concession.

It's February 7th. Nomura Kichizaburo landed at Wusong with more than 20 warships of his Third Fleet, as well as more than 10,000 people of the 12th Division, the 24th Brigade, that is, the Kurume Mixed Brigade.

At the same time, dozens of tanks and dozens of aircraft arrived.

As soon as Nomura Kichizaburo arrived in Shanghai, he couldn't wait to get rid of Shiozawa Yuki and take over his position as commander-in-chief.

And Nomura Kichizaburo, who was also eager to perform, also made the big mistake of underestimating the enemy, believing that under the attack of hundreds of aircraft, hundreds of tanks, nearly 50 warships, and nearly 20,000 elite Japanese troops.

The more than 30,000 miscellaneous troops on the opposite side, who did not even have heavy weapons and anti-aircraft artillery, would only be bombarded to pieces, so Nomura Kichizaburo, who was in a hurry to perform, did not listen to the relevant report of Major General Shiozawa Yuki about the Shanghai defenders.

He directly ordered the 24th Brigade, which had not gained a firm foothold, to divide its troops into multiple routes and raid the defenders of Wusong Fortress, and at the same time ordered the previous marines to attack Jiangwan and other places from the concession.

At the same time, he also asked Shiozawa Yuki to lead his First Fleet to bomb the downtown area of Shanghai together with his own Third Fleet.

Although the Chinese defenders were inferior to the Japanese army in heavy weapons and equipment, the army and the people were united in their efforts, relying on various main roads and taking advantage of the favorable terrain to resist step by step.

In addition, the Huaxing Guards participated in the war in an all-round way as the general reserve, and at this time the Shanghai Huaxing Guards had reached 3,000 people, and where the war situation was urgent, there was the presence of the Huaxing Guards.

Relying on their familiarity with the terrain, the Chinese defenders not only repelled the Japanese attacks many times, but also encircled and suppressed some of the Japanese troops who attacked the front many times.

Especially on 13 February, when the 19th Route Army launched a desperate charge with a death squad in front of the Yongan Yarn Factory, annihilating 1,600 soldiers of the 24th Brigade at one time.

The Japanese army finally recognized the fact that it was impossible to occupy Shanghai in a short time, and at this time, Nomura Kichizaburo remembered Shiozawa's advice to him when he stepped down, and warned him not to underestimate the enemy.

The 19th Route Army in Shanghai was different from the Northeast Army, they dared to fight, and in addition to heavy weapons, their various supplies were very sufficient.

As a result, from February 7 to February 14, another week, although the Chinese defenders suffered heavy casualties, the Japanese army led by Nomura Kichizaburo also suffered more than 5,000 casualties, and was no longer able to launch a full-scale attack.

On 14 February, Commander Chiang, who had regained power, ordered the Fifth Route Army led by Zhang Zhizhong and the Teaching Corps of the Chinese Army Military Academy to arrive in Shanghai, with a total strength of 50,000 troops.

Moreover, there were also a large number of recruits to supplement the 19th Route Army, and countless ordnance materials brought from Nanjing, including an aviation squadron and two artillery battalions.

It seems that Commander Chiang also knew that Shanghai could not afford to lose, and he could tolerate the Japanese occupation of Northeast China, but he could not tolerate the Japanese occupation of his money bag.

When Nomura Kichizaburo received reinforcements from Shanghai, he knew he had lost the chance to fight again. As a last resort, he cheekily asked for more troops in Japan again.

On the same day, the Japanese cabinet approved his request and sent the Ninth Division from Japan again to reinforce Shanghai under the leadership of the division commander Kenkichi Ueda.

Ueda's arrival in Shanghai did not change the tide of the battle much, because although the current Japanese army also had a huge advantage in heavy weapons, the lack of troops was still their greatest weakness.

At present, the defenders of Shanghai have reached more than 50,000 people, but the Japanese have only increased their troops twice before and after only more than 30,000 people, and the Chinese defenders are fighting on their own soil, and most of them are fighting street battles that are extremely unfavorable to the Japanese army. Many of the heavy weapons of the Japanese army did not play a huge role.

Therefore, Ueda Kenkichi, who had just replaced Shimonomura Kichizaburo as the new commander-in-chief of the attack on Shanghai, was also deeply frowned, but as the War Department, he snatched the power of the commander-in-chief from the Admiralty for the first time.

If the Japanese army in Shanghai can achieve results under his leadership, it will be a great glory for him, and even more so for the Japanese War Department.

So on the day of the 20th, when the 19th Route Army rejected the unreasonable demand of Japan to retreat 20 miles.

Kenkichi Ueda made the same mistake as his predecessors, and with a small number of troops, he made an all-out assault on the Chinese defenders.

Although the Japanese planes and artillery were more ferocious this time, they could not defeat the Chinese defenders with 20,000 against 30,000, let alone 30,000 against 50,000, especially after the Chinese side also received reinforcements from a squadron of aircraft and two artillery battalions.

In just three days, the soldiers on both sides suffered nearly 10,000 casualties, and suddenly Ueda Kenkichi was awakened, and he realized that with his current strength of 30,000 people, even if he was given multiple aircraft and artillery, he would not be able to defeat the Chinese defenders on the opposite side.

He couldn't understand how the Kwantung Army swept through hundreds of thousands of troops in the northeast with the same strength of more than 20,000 troops, and why the same Chinese soldiers could have such a big gap?

Is it true that a lion leading a flock of sheep can defeat a flock of lions led by a sheep?

He had no choice but to make the same choice as the previous two. That is to send a telegram to the country, and the demand is the same, that is, to ask for more troops in the country.

However, before the arrival of domestic reinforcements, Ueda Kenkichi did not want to sit idly by, since it was a lion who led a group of sheep opposite, then let him send someone to kill this lion.
