On the map, the Japanese defense line is spread out along the east-west direction, its Marine Corps Headquarters (now opposite the 411 Hospital in Hongkou Park) is the westernmost, Dagong Yarn Factory (now the Middle Ring Road near the Huangpu River) is the easternmost, this long snake formation is about seven kilometers in a straight line, it is impossible to garrison a seven-kilometer defense line with thousands of troops, so the deployment will only make the entire defense line weak, therefore, the Japanese Marine Corps Headquarters and the Dagong Yarn Factory are the main points of the Japanese army's defense.

After adjusting the offensive plan. The army prepared to divide this seven-kilometer-long defensive line from Yangshupu into two and go south to Huishan Wharf on the Huangpu River (on the west side of the present-day Dalian Road Tunnel, between Pingping Road and Qinhuangdao Road). The biggest danger of this 3.5-kilometer straight axis of attack is to enter the Yangshupu neighborhood. It is conceivable that in a plain area like Shanghai, where there is no danger of attacking, the Japanese army will definitely defend on the Yangshupu market, and in the streets and alleys where it is inconvenient to dodge and deploy, their 37mm anti-aircraft guns will easily open tanks. Thinking of this, Du Yuming sweated, but now he can only wait for the investigation report of the search company. When it was close to eleven o'clock, Major Ma Zhe, who personally led the reconnaissance, returned.

"Brigade, only these few places are weakly defended." Ma Zhe pointed to Qiqihar Road and Jiangpu Road, which are next to Yangshupu River, and Weituma Road (now Huaide Road) and Xuchang Road on the west side. "You can't go to Baoding Road, and it can be judged that the defense of places with Japanese-funded factories is very tight, and the defense of places with few Japanese-funded factories is relatively weak. We can only attack in a roundabout way. ”

"What if the devils on the road in Baoding rush over?" Du Yuming nodded and asked a question.

Although he was very reluctant, Ma Zhe still said: "There is no way, you can only rely on the infantry to fight hard." ”

"What do you think?" Du Yuming has nothing to do about it, he is not familiar with the terrain, and he has no time to investigate, so he can only plunge into it like luck, and only God knows what the result is.

Peng Bisheng, deputy of the colonel's regiment, Dong Jiarui, deputy of the lieutenant colonel's regiment, and Hou Teng, who was full of solemnity, had no opinion on this. Peng Bisheng said: "It's right to avoid Japanese-funded factories, there must have been fortifications in those places long ago, even if they move their positions, it will only be a temporary position, as long as the infantry is strong, they can still rush through." ”

Peng Bisheng said here that everyone's eyes were on Major Li Jirui of the motorized infantry battalion, who was originally the commander of the 1st company of the search battalion, and after the expansion of the armored regiment, he became the commander of the 1st motorized infantry battalion. "As long as there are motorized infantry, the motorized infantry battalion will never lose a tank!" Major Li Jirui shouted. He was a standard revolutionary soldier with spirit first.

"How about your side, can the artillery support it?" Du Yuming finally looked at Lieutenant Colonel Xie Chengzhang of the self-propelled artillery battalion, who was originally a member of the combat defense artillery training team, but became the commander of the self-propelled artillery (mortar) battalion after the expansion.

"It's okay on my side." Xie Chengzhang said in a low voice. In the past month, he has also learned the art of multi-arms joint operations, but this is the first time he has fought, and it is still a street battle where he can't see the situation on the front line, so he can't help but feel a little hairy, so he added another sentence after he finished speaking: "The communication must be able to keep up, and if the telephone line is broken, the shells will not know where to fire." ”

"Communication is fine." Hou Teng personally supervised the communication, "Just three or four kilometers, the telephone line can't be broken!" ”

"Then let's fight, all the departments are in place!" Du Yuming glanced around at everyone, saw that everyone's heads were sweating, but their eyes were blazing, and finally said.

"What about the two 88 guns?" Lieutenant Colonel Lin Zehuan of the anti-aircraft artillery battalion asked.

"Hold in the rear and let the infantry of the 522nd Regiment surround me. This is a fortress cannon, and it will have to be returned when the time comes. As soon as Du Yuming said that the artillery would be returned, everyone laughed, the anti-aircraft guns of the anti-aircraft artillery battalion had been given to the Jiangyin fortress, and there was no reason for the 88 anti-aircraft guns to be returned.

At 11:30, the mountain artillery on the side of Hongkou Park in the west rang out - the division commander Sun Yuanliang is also a believer, although the mountain artillery of the 88th Division is no longer needed to suppress the Japanese firepower, but the lookout post above the Japanese Marine Corps Headquarters is a very annoying existence, and they will definitely see the armored regiment in the all-out attack.

Within ten minutes of the artillery fire from the west, the 1st Tank Battalion of the Panzer Regiment, which had already set up its position, moved forward without artillery fire. Sixteen Vickers six-ton tanks formed a wedge-shaped formation and approached Kunming Road on the east-west side of the US concession.

The soldiers of the 87th Division, who had been fighting fiercely on the front line for several days, had always seen the Japanese armored vehicles, and now they saw their own armored vehicles coming up, and they immediately cheered. There were no decent streets and alleys outside the US Concession, just a wasteland, and the time of the attack was chosen was lunch time, there were no Japanese planes in the sky, and the Japanese artillery on the ground did not react quickly, and when the Japanese artillery shells roared behind them, more than 30 Congdapu two-wheeled motorcycles, 16 tanks, 18 trucks (mortars), four whiskered armored vehicles, and towed 88mm antiaircraft guns of the entire armored regiment had been wedged into the US Concession.

The armored regiment entered the concession, and the soldiers of the 522nd regiment followed, and at this time the fierce exchange of fire sounded in the streets and alleys - according to the warning of the armored treasure book, the street fighting tanks were in groups of two, covering each other. In fact, this is also the helplessness of the armored troops' street fighting, because no matter how wide the street is, it cannot open the whole army, so the streets of this attack from east to west are Qiqihar Road, Jiangpu Road, Weituma Road (now Huaide Road), and Xuchang Road, each street has two groups of four tanks, the front group is responsible for opening the road, and the back group is responsible for cutting horizontally to clear the Japanese troops on the crossroads.

On Qiqihar Road, the tank of Zheng Shaoyu, the commander of the 1st Company, rushed to the front, but before it entered the street, there was a 'boom', and a 37mm anti-aircraft shell hit the side of the tank, and the sound almost shook out the company commander Major Zheng Shaoyu, who exposed his upper body. As soon as the Japanese anti-aircraft artillery fired, the mortar behind the tank immediately hit it, more than a dozen shells bombarded it, the corner of Jiangpu Road was full of smoke and dust, and the department store with a big sale sign collapsed a wall, and no one knew whether the Japanese anti-aircraft artillery was buried in it.

"Onward! Advance! "The 37mm anti-aircraft gun hit the side of the Vickers tank, but fortunately a row of wood was tied with wire on the outside, otherwise the shot just now must have penetrated the tank's poor 13mm armor. The armor was not penetrated, but the tank was extinguished, and the flying sawdust sprayed Zheng Shaoyu's face, but fortunately, the tank started again after a while, and roared into Qiqihar Road.

"What a cunning wolf!" Driving into Qiqihar Road, but not seeing the Japanese counterattack, he couldn't help cursing the major who was extremely frightened by the shot just now - the Japanese hid in the houses on both sides like rats. He could almost be sure that the interiors of the houses had been opened by them, and the would-be robbers were huddled inside, waiting for their flaws to be revealed.

Qiqihar Road enters, crosses Kunming Road, the west side to Jiangpu Road is an overgrown open space (now Jiangpu Park), the east side is one to two storey houses, until after crossing Huade Road (now Changyang Road) near Huoshan Road, there are the same houses on the west side, and the houses on both sides are sandwiched into a complete street, and the resistance of the Japanese army also begins here.

The armored regiment had previously been caught off guard by breaking into the US concession, and due to the flat wasteland between Jiangpu Road and Qiqihar Road, the Japanese army could only set up a sniper position at the intersection of Huoshan Road, which ran east-west behind Huade Road. Here, sacks filled with sand and gravel are at the intersection of Qiqihar and Huoshan Road, and the barricades not only expose rifle shooting holes, but also two battle defense gun shooting holes. Huoshan Road is only a short distance of more than 170 meters from Huade Road, which is parallel to it, and Zheng Shaoyu's tank just drove through Huade Road when two anti-aircraft guns immediately opened fire. The sound of artillery is an order, and as soon as the Japanese artillery sounded, the originally empty houses also stretched out countless muzzles and began to shoot.

"Bang-boom!" A 37mm shell hit the edge of the front armor of the Vickers tank, and the tank shook again, but this time it still did not penetrate the armor; Another shell hit the tank ten meters in front of it, sending only countless sand and gravel up to it. The tanks were glad to be safe, but the infantry that followed closely behind them were caught off guard by the sudden burst of gunfire - they had no idea that the bullets would come from behind. Fortunately, the tanks were one in front of the other, and the motorized infantry in the back either lay down on the side of the street, or rushed between the two tanks to find cover, and counterattacked with guns.

"Bang!" Zheng Shaoyu's front car finally opened fire, but the smoke cleared, and he realized that the shells could not penetrate the Japanese barricades at all, and the tanks behind him fired at a civilian house on the right, where the machine guns had been suppressing their infantry. As soon as the cannon passed, a hole was immediately blown open in the house. The infantry was rushing up to make up for it, but after a few steps, another machine gun appeared on the roof on the left, and the chain of flames reaped the lives of their own soldiers.

"Retreat! Retreat! Zheng Shaoyu's forehead was full of sweat, and he felt that he was in ambush. He opened the roof of his car and waved the green flag and shouted loudly - since last month, the armored brigade has compiled a simple communication manual, including vehicle-to-vehicle communication and vehicle-to-person communication.

The No. 045 car in the back saw the flag of the front car and immediately began to reverse, and the motorcycle infantry also retreated along the streets and alleys, fortunately, it was not a few tens of meters from Huade Road, and as soon as the tank retreated, it was an open field between Jiangpu Road and Qiqihar Road, which had been occupied by soldiers of the 522nd Regiment.

"Bring up the 88 gun!" Major Zheng Shaoyu, who withdrew from the street, had a tiger face and shouted loudly to the company commander of the motorized infantry company, "Otherwise, you won't be able to penetrate!" ”

The Chinese tanks stretched out more than 10 meters and retracted after firing two shots, and the Japanese stationed at the barricade immediately shouted 'onboarded'. To tell the truth, they are actually very afraid of tanks, and now that the tanks have actually retreated, how can they make people unhappy.

"How could you just retreat!" In a hidden observation post on the north side of the US Concession, Lieutenant General Wang Jingjiu was immediately unhappy when he saw that the tanks that had rushed into the streets and alleys had retreated so quickly. Even the retreat of the party-state soldiers can only be called 'turning in', otherwise it will damage the revolutionary spirit. Who wants the tanks of the armored regiment to not even 'turn' and retreat directly, which of course displeases him, if this matter is known to the principal, then ......

"There must be a reason." The commander of the 1st Battalion, Zheng Shaoyu and Du Yuming, knew about it, and he was sure that there was a reason for his withdrawal. After a while, the phone from the front line came, and it was the voice of Lieutenant Colonel Lin Zehuan of the anti-aircraft artillery battalion. “…… Brigade seat, it was said earlier that tank artillery can't penetrate the barricades, and Company Commander Zheng wants to drop 88 guns to bombard! ”

"88 guns are going to be adjusted so soon?!" 88 cannons are treasures, even if he has seen the world in Europe, Du Yuming is still reluctant.

"Yes, Zheng Shaoyu said that the Japanese barricade tank guns can't penetrate at all! He fought! Lin Zehuan shouted urgently on the phone, now that the offensive has begun, the Japanese will have one more minute to prepare for every minute of delay.

"Tune! Turn it up! Du Yuming hesitated in his heart, but Wang Jingjiu was looking at it with fierce eyes, and he could only bet on it!

In another period of history, the failure of the ten-day siege was not at all due to the fact that Chang Kaishen shouted three times to stop as mentioned in Zhang Zhizhong's memoirs, which made the offensive fall short.

The most fundamental reason why the ten-day siege did not achieve the goal of the campaign was the underestimation of the enemy and the lack of sharp weapons to attack the fortifications. The former has been affected until the 19th, during this time Zhang Zhizhong thought that the troops could bypass the construction and take advantage of the gap, but in fact, the Japanese army was extremely well prepared, the streets and alleys and houses were all turned into fortresses, and the firepower points were crossed, and there was no so-called 'gap' at all, and the revolutionary soldiers with the revolutionary will rushed in as many as they died, and on the first day of the attack, just on the periphery, Major General Huang Meixing, commander of the 264th Brigade of the 88th Division, hung up - a team that had not participated in the European war, The troops, who also did not study the European war, simply could not imagine that the firepower had reached an unimaginable level.

After adjusting the attack, he suddenly found that the troops lacked combat engineers and heavy artillery direct firing technology - it was not that there were no combat engineers, there were them during the 128th Anti-Japanese War, but after five consecutive years of suppressing the Communist Party, dealing with the 'communist bandits' who were scared to run and flee in the wilderness, why did the revolutionary army need combat engineers? With a high revolutionary spirit and the pride of a German kettle and steel helmeter, it was a dozen and no battles for five days in a row, and only then did he realize that the Japanese army was by no means a 'communist bandit'. There were no combat sappers to carry out blasting, no direct fire to collapse the enemy's fortifications, and they all relied on infantry charges, and as long as the Japanese army was not short of ammunition, even if the 9th Group fought for a year, it would not be able to take the Japanese stronghold.

"Attention guns! The target is the Japanese barricades, five hundred away. ”

"Yes! Target the barricades of the Wakos, five hundred away"

"Grenade one-shot reloading."

"Grenade one-shot reloading."

"One shot of the base gun, rapid fire!"

"A rapid fire!"

"Put!"

"Put!!"

In the rain of bullets, Lieutenant Colonel Lin Zehuan, commander of the antiaircraft artillery battalion, personally commanded the firing of the artillery, and after the artillery commander repeated, the 88mm antiaircraft gun weighing eight tons 'banged' and spit out flames several meters long, and the shells weighing 10 kilograms bombarded the Japanese barricades on Huoshan Road at a speed of 810 meters per second.

"Boom!!" The shells did not hit the barricades, but only on the houses next to the barricades, and the explosion not only stirred up smoke and dust in the sky, but also blew up an entire area of houses.

"Five hundred and twenty at a distance, twenty-five to the right. Grenades, rapid fire! Put!! ”

"Bang... Bang......" The 88mm anti-aircraft guns continued to roar, and by the time Lieutenant Colonel Lin Zehuan shouted 'stop shooting', the Japanese barricades on Huoshan Road had disappeared.
