At the beginning of September, Lao Jiang, who personally served as the commander-in-chief of the Songhu Battle, accompanied the large army to the Songhu battlefield one after another, and redeployed all the participating troops to form the Central Route Group Army, the Left Wing Group Army, and the Right Wing Group Army. Chen Cheng was the commander-in-chief of the Left Wing Group Army, under the jurisdiction of the 15th and 19th Group Armies. The combat areas are Wanqiao, Luodian, and Guangfu. Due to Zhang Zhizhong's poor health, the commander-in-chief of the Central Route Group Army was replaced by Zhu Shaoliang as commander-in-chief, with 7 armies and 18 divisions under his jurisdiction, and the operational area was the North Station, Jiangwan, Miaohang Line and the area west of it.

The commander-in-chief of the right-wing group army is Zhang Fakui, who has jurisdiction over the 8th and 10th group armies. The combat area is south of Suzhou Creek and north of Hangzhou Bay. The total strength of the national army has reached 800,000, and the Japanese army has put 250,000 troops into the battlefield, of which 100,000 men and horses of the supporting 10th Army are still at sea. Due to the stubborn defense of the Left Wing Army, the Japanese army's attempt to flank the main forces of the Nationalist Army could not be achieved. Immediately, Matsui Ishone ordered the middle to break through. Since Oba was located on a protruding position in the circular defensive line on the southern bank of Fumohama, Oba became the focal point of the Japanese attack.

The 3rd Division of the Japanese Army, the 41st Division of the Kwantung Army, and the 45th Division of the Kwantung Army launched a fierce offensive with the intention of breaking through in the middle. Defending the field is the tax police regiment of the Shanghai State Administration of Taxation. Don't look at the tax police regiment as a unit, but its strength is tens of thousands, and it is well-trained and well-equipped. The head of the tax police regiment is Sun Liren, a handsome general. The 41st Division of the Japanese Army put 40 tanks and combat vehicles on the front line of Dachang, and under the cover of fighters and artillery, launched a tidal offensive.

The tax police regiment stubbornly resisted for two days and suffered heavy losses, and the front was precarious. The forward position changed hands several times and was recaptured, in the face of the Japanese tide of offensive, the defending soldiers who were pressed were almost breathless, especially the Japanese tank fighting vehicles showed their might, in order to blow up a Japanese tank, the soldiers of the tax police regiment had to pay the price of at least 20 soldiers. As darkness approached, the Tax Police launched a counterattack with the aim of regaining the positions lost during the day. Outside, guns and artillery were thundering and bullets were raining down, and inside the regiment headquarters, regiment commander Sun Liren had a solemn expression and frowned.

"Regiment commander, we recaptured the lost position at night, but tomorrow the position will be lost again during the day, and our losses are too great to bear!" A subordinate spoke. "The big field is the main point that cannot be lost, no matter how much it costs, it must be stubborn, even if the troops are exhausted, it will not hesitate." Sun Liren thought of the consequences, but as a commander, he could not waver in the slightest. Sun Liren continued: "Order all departments to organize death squads to deal with the Japanese army's armored fighting vehicles. "The brutal battle is fought to this extent, even if you resist it with flesh and blood, you have to fight with all your might. The tragedy on the battlefield has numbed all the officers and soldiers participating in the battle, and everyone has only one belief in the bloody battlefield.

"Report to the regiment commander, Commander Chen of the Left Wing Army has called you!" Sun Liren answered the phone with a straight chest, but his expression was a little confused. "Thank you Commander Chen for your strong support, please rest assured, Chief Chen, and promise to stick to the big field." Sun Liren put down the phone and faced everyone's equally confused eyes and said: "Commander Chen is very concerned about the safety of Dachang, and his department has sent a bazooka company to deal with the Japanese army's armored fighting vehicles. It will take about half an hour to arrive, and in addition to 100 thunder cannons and 1,000 shells to be delivered tomorrow morning. ”

"Regiment commander, bazooka company, it must be our new weapon, great! But what is this Flying Thunder Cannon? "A subordinate is confused." Don't be suspicious, you'll know when the weapon arrives! "About half an hour later, two trucks arrived, and the soldiers got out of the cars with bazookas on their shoulders. After a while, the commander of the bazooka company walked into the regimental headquarters with a bazooka and a rocket. With the captain's careful explanation, Sun Liren looked at the bazooka and rockets and secretly thought in his heart: This weapon is well-made, and the weapons industry of the Republic of China cannot develop this kind of weapon at all, and it is obviously purchased from abroad.

Perhaps this new weapon had just been transported from Nanjing, and Sun Liren said with a refreshed expression: "Immediately put the bazooka company into the forward position, and order all units to protect the bazooka and never fall into the hands of the Japanese army." "That night, the bazooka company dispersed into the forward position. Early in the morning, two trucks arrived at the main field with 100 flying thunder cannons and 1,000 flying thunder "shells". The flying thunder cannon is easy to learn and understand, and the operation is simple, and Sun Liren quickly formed a 300-person flying thunder artillery team.

It stands to reason that Sun Liren should test fire and see it, but the rockets and flying thunder shells are too expensive and can only be tested in actual combat. In the early morning, the Japanese artillery fire was overwhelming, and the ground shook. After the heavy artillery fire extended, dozens of armored fighting vehicles approached head-on. In order to prevent the armored fighting vehicle from being blown up, the charging soldiers followed closely behind the armored fighting vehicle. Although the tax police regiment was well armed, the number of artillery pieces was small. Even if there was artillery fighting for days, it was taken care of by the Japanese artillery, or it was blown up by Japanese bombers. At the moment, the only support artillery fire of the tax police regiment is mortars.

The terrain is flat and undefendable, so it is very suitable for Japanese tank and combat vehicle attacks. A Japanese tank in a certain position swaggered in a straight line, and the tank machine gun formed a dense rain of bullets, so that the defending soldiers could hardly raise their heads. The Japanese tank was firing frantically as it drove fast. After entering the 100 meters, I saw two rockets flying straight into the Japanese tank. One shot did not hit the target, and the other hit the position of the tank turret. With the violent explosion, the upper half of the tank was missing, and the tank track inertia rushed forward a few meters and stopped.

The Japanese troops who charged behind hurriedly lay on the ground, looking at the terrifying scene of the destruction of the tank, not knowing what had happened. There is no doubt that the three tank crews are dead. Just when the Japanese soldiers were in shock, a tank on the right flank was hit. The tank did not hit the vital part, but hit the left side. However, with the violent explosion, a large hole was blown open on the left side of the tank, and a fire broke out. The driver of the tank was killed on the spot, and the machine gunner and gunner drilled out of the turret with fire burning on their bodies, and then jumped to the ground and rolled.

At this time, a dense burst of bullets hit the two rolling Japanese tank soldiers, and they were immediately beaten into a sieve······. The Japanese offensive soon came to an aborted end. In the regimental headquarters, an operational staff officer put down the phone and reported loudly: "Regiment commander, the rockets have shown their might, destroying 6 Japanese tanks, and the Japanese army has retreated." When Sun Liren heard this, he immediately picked up the phone, and he wanted to verify them one by one. Six tanks were killed, and the Japanese front-line commander judged that it was the anti-aircraft artillery that did it, and immediately notified the air force to support.

After several hours of bombardment and artillery coverage, the Japanese fighters began a new round of attacks. The Japanese threw 20 tanks into the attack. The Japanese commander made a mistake in judgment and was naturally punished. When the Japanese army destroyed another 8 tanks, it suddenly dawned on the Chinese defenders that they had new weapons specially designed to deal with tanks and combat vehicles. The Japanese army did not organize a new offensive throughout the afternoon. The rockets displayed their might, greatly boosted the fighting spirit of the soldiers, and swept away the gloom of the past few days. With the help of new weapons, Sun Liren decided to launch a counterattack and regain the position lost a few days ago.

In the dark night, more than a dozen flying thunder guns quietly pointed at the Japanese position. With a command, the flying thunder cannon fired a salvo, and a violent explosion exploded in the Japanese position, and the roar was like a heavy artillery bombardment. In less than an hour, the position, which had been occupied by the Japanese, was recaptured. In the regimental headquarters, Sun Liren held a telescope to check the battle situation in front and said excitedly: "The explosion sound of the flying thunder cannon is like a heavy artillery, which seems simple and extremely efficient. All the generals were also smiling and excited.

At midnight, a Japanese corpse was carried to the regimental headquarters. A front-line commander introduced: "Regiment commander, this Japanese soldier was not wounded, but died of blood. The explosion of the Flying Thunder Cannon was huge, and we judged that it was a new type of gunpowder. Sun Liren carefully examined the bodies of the Japanese soldiers, and then picked up the phone to report to the headquarters. Frankly speaking, one or two new weapons will not turn the tide of the war at all, and the national defense line is still precarious. The Japanese army would not be desperate, and then the Japanese army changed its fighting style, increased the density of air raids, and increased the intensity of artillery strikes.

The Japanese army had no choice but to change its tactics, and the tanks stopped advancing after a certain distance, and used the tanks as a fulcrum of fire to cover the infantry attack. Although this move caused some casualties to the defending soldiers, the intensity of the Japanese attack was greatly reduced. In fact, the greatest casualties of the Nationalist troops came from Japanese artillery fire. Since the vast majority of the Nationalist Army's tactical thinking is still stuck in the period of World War I, especially for the saturation of firepower in modern warfare, especially the coverage of defensive areas by heavy artillery firepower, there is not enough understanding, and the scene is simply unimaginable.

It can be said that 80 percent of the casualties of the Nationalist army came from the Japanese artillery fire and air strikes, and because the number of artillery fires of the Nationalist troops was already small, the brutal battles were fought to such an extent, and the losses of the artillery were already 7788 from the three-dimensional ravages of the Japanese army. However, with the rockets and flying thunder artillery put into the battlefield operation, the Japanese army was not prepared at all, and was taken by surprise, especially the battle loss rate increased significantly, and the Japanese attack was effectively contained. The Japanese army suffered heavy losses in Luodian and Dachang, and the battle situation entered a state of scorching.

In the headquarters of the Shanghai Dispatch Army, Commander Matsui Ishine was shocked when he heard the battle reports from the front line, especially from the key offensive areas. It is unbelievable that 28 tanks were destroyed by the Chinese army in three days. "What kind of weapon is the other party using?" Matsui Ishone asked. An operational staff officer replied: "Your Excellency, the enemy is using a shoulder-mounted barrel weapon, which is fired by individual soldiers. As soon as the weapon hit, the armored combat vehicle was destroyed. ”

Another combat staff officer continued: "Your Excellency, commander, according to the enemy's weapons and equipment, this is a newly developed weapon. In addition, the enemy used an earthen cannon that, according to reports from front-line soldiers, fired round explosive packets with a range of about 300 meters. The explosion of the earthen cannon was extremely powerful, and we judged that the earthen cannon used TNT explosives. Judging from this, China's weapons industry has secretly developed TNT explosives. Matsui Ishine was silent when he heard Tetsu's face turned blue. ，

The lack of attack increased the pressure on Matsui's body, and he looked at the military map and realized that it would be difficult to break through the Chinese army's defense line head-on, even if the cost of the breakthrough was unbearable. He subconsciously aimed at Hangzhou Bay and asked, "Where has the 10th Army arrived?" "Report to the commander, the 10th Army has reached the Yellow Sea, and it is still a day's journey from Wusongkou." "Order the 10th Army ······."
