The Japanese army, the response is also fast, after the ** exit from Shanghai, immediately occupied the whole city of Shanghai, while sending troops to pursue, before the first defense fortifications, began a tentative attack, repulsed by the Chinese defenders, with the deployment of the Japanese army in place, the Japanese army began to use 200,000 troops to storm the Wufu line and Zhapu line, the Wufu line is on the right side of Taihu Lake Zhapu line is on the left side of Taihu Lake, the Japanese army used all its strength and used all weapons, including poison gas bombs, still did not completely break through these two defense lines, the defense line of five to the defense line echelon equipment, Before the Japanese army did not use the armored cluster, it was only possible to rely on soldiers on foot to break through, only to suffer heavy casualties.

After the war, Gu participated in the war veterans' recollection, in 1935, Yu Deyuan joined the Northwest Army General Yang Hucheng Special Service Group (that is, the guard regiment). After the Battle of Songhu broke out in 1937, General Yang Hucheng dispatched the elite forces of the 17th Route Army to form a reinforcement group to Songhu, and Yu Deyuan was ordered to go to the expedition.

Each of the 1,800 hot-blooded men was armed with a 4-kilogram knife, a machine gun and six grenades and marched to Shanghai. After arriving in Shanghai, they were assigned to the 88th Division and held a section of the Wufu Line. The enemy was well-armed, and the Japanese tanks were on the opposite side, but the soldiers shouted "We must not let the Japanese take down the position", and would rather die than be slaves to the country!

Machine guns fired, shells flew sideways, and the fighters fought bloodily. Soon, the water in the trenches turned red, and people were constantly being wounded and killed. Whenever a comrade-in-arms died by his side, Yu Deyuan would shout: His grandmother's!

Once, Yu Deyuan was shooting next to the cover, only to feel that his forehead was hot, and his eyes suddenly couldn't see anything, a bullet flew over his forehead, and blood covered his eyes, but he didn't care about bandaging at all and continued to fight. In the following battles, Yu Deyuan's left leg and neck were hit by bullets successively, but as long as he could still move, he would definitely insist on fighting.

Soon, the bullets ran out, and I don't know who shouted: "We can't retreat anymore, even if there is only one person left, one shot and one bullet, we must persevere to the end and live and die with the position!" Yu Deyuan took out his big knife and rushed forward. When he was in Xi'an, Yu Deyuan was a soldier of the big knife squad and studied the Japanese knife technique. Dialing, blocking, stabbing, and when he came up, he cut off the head of a Japanese soldier. Before he could catch his breath, another Japanese soldier came up. The big knife flew over, blood and flesh splashed, Yu Deyuan didn't know when the battle ended, he only felt that the Japanese soldiers in front of him were gradually decreasing, and when he stopped, he only felt that his hands and feet were sore, and at this time, he had cut down 13 Japanese soldiers.

After more than a month of fighting, by the time he returned to Shaanxi in October 1937, there were more than 600 people left in the 1,800-strong team, and then went to Shanxi to fight devils

Memories of Major General Sichuan Army:

On August 13, 1937, when the Songhu Anti-Japanese War broke out, Du Chongshi served as the director of the Major General Division of the 20th Army of the Sichuan Army in Shanghai. On the orders of Chiang Zhongzheng, under the leadership of army commander Yang Sen, the soldiers of the 20th Army wore their own straw sandals, bamboo hats, and some carried oil-paper umbrellas.9

On the 1st, he set out on foot from Anshun, Guizhou, marched along the Hunan-Guizhou Highway, took a boat to Changsha in Chenxi, Hunan, changed to a train to Xujiapeng Station in Wuchang via Yuehan Road, crossed the river to Hankou overnight, and then changed to a train on the Beijing-Shanghai Line from Hankou to Pukou, and arrived at the Nanxiang Railway Station on the front line in Shanghai on November 12.

On November 15, the troops were engaged in the battle to defend the defense line, and the 134th Division of the 20th Army was attacked by the Japanese on the first day, and the fierce battle began.

"The enemy was under fire, and I pushed a military cap out with a bayonet in the trench, and in the blink of an eye the hat was punched with a dozen holes." Du Chongshi recalled, "Our team joined the front line one division at a time, and some divisions were reduced by half in one day on the front line, and some were reduced by two-thirds after two days of support. The battlefield is like a furnace that melts people as soon as they fill it. ”

On November 16, Lin Xianghou, the head of the 802nd Regiment, was martyred. Lin Xianghou's troops fought fiercely with the 9th Division and the Praetorian Guard Division under the command of General Shirakawa, and the Japanese army launched a fierce attack by virtue of its weapon superiority. On the evening of the 16th, the Japanese army launched another round of offensive, the soldiers poured in like a tide, the position was not secured, Lin Xianghou rushed out of the trench, the roar shook the sky, and he was shot in the head and fell. Lin Xianghou was the first regimental commander of the Sichuan army to sacrifice his life for the country on the battlefield of Songhu, and he died in this posture: his eyes were wide with anger and his fingers were pointing forward......

The 20th Army held an inch of position with flesh and blood, and also recaptured the Chenjiahang position lost by the 23rd Division of the Central Army. On November 18, the 804th Regiment was ordered to regain the lost position. The regiment commander Xiang Wenbin led his troops to fight fiercely that night and recaptured the position, but the officers and soldiers of the whole regiment, the battalion commander only had Peng Huanwen left, the company platoon commander was either injured or killed, and none of them were spared, there were 4 squad leaders left, and there were only more than 120 soldiers left! Within three hours of one day, Xiang Wenbin was promoted from lieutenant colonel to colonel, and from colonel to major general......

On December 5, Yang Sen was ordered to hand over the position to the Guangxi troops for defense. At this point, the 20th Army ended the 20-day and night-day Shanghai War of Resistance, and was ordered to go to Jiwangmiao to rectify the remnants, and the remnants of an army could only be reluctantly organized into a brigade.

The ground forces are fighting in blood, and the air force is also desperately trying to protect the airspace on the defense line, the Japanese army's Kisarazu air force and 96 carrier-based aircraft under the repeated ambushes of the air force, the result is heavy losses, but the air force's more than 100 fighters are also about to run out, originally the air force has more than 300 fighters, but more than 100 can not take off, can only become a supplier of accessories, otherwise the war is now the air force has no aircraft accessories.

Fortunately, because of the hatred between the Soviet Union and Japan, the Soviet Aviation Volunteer Corps, with a total of more than 100 fighters and more than 40 bombers, barely managed to maintain half of the air supremacy on the defense line, resulting in countless air heroes who can sing and cry.

At 2:30 p.m. on October 29, dozens of Japanese fighters took off from Shanghai in a multi-layer formation and secretly attacked Nanjing. The Chinese Air Force and the Soviet Volunteer Air Force were on standby, dispatching dozens of warplanes into the air to intercept them.

The sound of guns and cannons in the sky was like a huge magnet, attracting more and more attention from the ground. Judging from the existing photographs, many Nanjing citizens at that time walked out of their homes and poured into the streets, closely watching the battle in the sky. Some people have serious and nervous expressions, others have smiles, and it is clear that everything in heaven tugs at people's heartstrings. The Chinese warriors really lived up to expectations, fighting more and more bravely in front of their own homes, desperately killing the enemy.

Huaimin's fighter is the wingman of Dong Mingde, deputy captain of the 4th Brigade. They galloped through the air, successively damaging enemy planes. After a fierce battle, Huaimin happily shot down an enemy plane and attracted the siege of several red-eyed wolves. Five enemy planes bit him to the death, surrounded him, and concentrated their firepower. The fuel tank of the Huaimin plane caught fire and the maneuvering was ineffective, and the plane smoked and went downward. At this time, enemy bullets also hit him in the chest.

At this critical juncture, Huaimin could have parachuted to survive in accordance with the operating procedures. However, to the astonishment and emotion of countless people on the ground, Huaimin flattened the plane, flipped it 180 degrees upside down, and struggled to rush towards an enemy plane approaching at high speed. The pilots of the enemy planes never dreamed that the Chinese pilots would be killed. In an instant, the two planes collided and exploded in the air, filling the air with black smoke and red flames. Huaimin was ejected from the cockpit and immediately fell to the bottom of the river, and the wreckage of the plane also fell into the river.

This scene in the sky, so unexpected, so tragic, shook everyone's heart.

Huaimin's feat quickly crushed the will of the enemy. Under the joint attack of the Chinese and Soviet air forces, which became more and more courageous in the Vietnam War, the Japanese air force finally could not parry, and the bombers took the lead in turning around and fleeing. Strings of bullets poured into the sky in a roar of rage and flew towards the enemy plane. The flames of revenge burned in the sky, and falling pieces flew in the air. Balls of fire shone and fell, and the sky over Nanjing became a huge crematorium for the Japanese Air Force.

The battle lasted only half an hour, but it shot down 21 Japanese planes in one fell swoop, including 11 fighters and 10 bombers. The Chinese Air Force lost 12 fighters and suffered 5 casualties. The "29 April" air battle was the most glorious air battle victory since the War of Resistance Against Japanese Aggression.

The next day, major newspapers and periodicals reported on this great air battle that shocked the world, and countless Chinese people rejoiced and felt infinitely sorry for Huaimin's feat.

Although Huaimin died, his spirit was still there, and he touched countless Chinese sons and daughters.

Countless sons and daughters of China are guarding their motherland with blood, inch by inch of rivers and mountains. Anyone who dares to invade China will be sent to hell by the sons and daughters of these heroes. Because the squadron relied on strong defense fortifications, the well-armed Japanese army paid an unimaginable price, and it took a whole month to break through the three lines of defense fortifications, and each defense fortification line was five lines of defense, with nearly 80,000 casualties and nearly 60,000 Japanese casualties, and the results of this month were 1.5 times that of the previous month.

The local security regiments of Jiangsu and Zhejiang provinces were all transferred to Nanjing, and then quickly replenished to the front-line troops, but the Japanese army had to be transported from the mainland, so the Japanese army had to increase its troops again, directly transporting 100,000 supplementary troops, and a large number of weapons and ammunition, and at the same time there was a tank wing, more than 300 tanks and a heavy artillery brigade, equipped with more than 100 heavy guns of 150 mm caliber, and more than 300 other cannons.

When the Japanese army was reinforced again, it immediately launched a more fierce attack, and under the cover of its tanks, it attacked the national defense fortifications, due to the lack of anti-tank guns, it could only use the death squad to bomb the Japanese tanks, and the Japanese army's heavy artillery bombarded the defense fortifications indiscriminately, and the damage was very serious.

That night, Jiang Zhongzheng saw that the first and second lines of defense could no longer be held in the case, and ordered to abandon the Wufu line and the Zhapu line, the Zhapu line retreated to the Hangzhou and Huzhou line to fortify, and the defenders of the Wufu line retreated to the Xideng line to do the final resistance and attrition.

In the distance from Hangzhou to Shanghai, it can be said that the rivers are vertical and horizontal, and the water network is dense, and it is very difficult for the Japanese army's mechanized troops to attack from Hangzhou to Nanjing, but it is different to attack from Wuxi, and there is no river in Pingchuan, which is very conducive to the Japanese army's mechanized troops. Therefore, the focus of the Japanese attack was on the Xideng line, and in the direction of Hangzhou, the Japanese army only left some alert troops.
