At 13 o'clock on December 10, Matsui Ishone issued an order to attack the city. More than 200 combat aircraft, more than 500 tanks and combat vehicles, and thousands of artillery pieces were dispatched, and the 9th Division launched a fierce attack on Guanghuamen, the 114th Division and the 6th Division towards Zhonghuamen, and the 16th Division on Purple Mountain.

The task of air cover was carried out by the Kisarazu Brigade of the Japanese Air Force. They met again in the sky over Nanjing. 13 "The old opponent of the Shanghai air battle - the 4th brigade of the Chinese Air Force hero Gao Zhihang. Most of the members of the 4th Brigade are air heroes who are loyal, defend the country, and have made repeated achievements. At this time, the enemies were very red when they saw each other. The original planes of the Kisarazu Brigade were almost all wiped out by the 4th Brigade. All that was flown this time was a re-replenished Type 96 aircraft.

The 4th Brigade was also supported by volunteer pilots of the Soviet Air Force, who fought side by side. Chinese and Soviet pilots bravely met the Japanese planes. The fighters painted with the blue sky and the white sun and the Japanese planes painted with the sun flag flew up and down, and they became a ball. The rumbling of artillery in the air was heard on the ground, and it was impossible to distinguish which side was firing, and only when they could clearly see the sun flag sign on the plane dragging the smoke down, did the officers and men defending the city and the people cheer together.

The teaching corps defending the Purple Mountain was like a floodgate, resisting the enemies who were surging like a tide in front of Nanjing. The teaching corps relied on the preset position of reinforced concrete to stubbornly block the enemy. The Japanese army was littered with corpses in front of the position, but a large number of Japanese troops continued to swarm up, and the teaching corps suffered heavy casualties. At this time, Gui Yongqing's order came from the phone, only a short 16 words: "Resolutely resist and can't retreat, if there is a mistake, come and see you." ”

Under the pressure of this death order, the teaching corps was in a hurry, relying on powerful terrain and fortifications, using a small number of troops to maneuver around the enemy, and the troops took turns to rest, which not only reduced casualties, but also recuperated and recuperated. This trick really worked, and the Japanese army lost its troops and still couldn't move an inch.

The cunning Japanese army knew that the hard bone of the teaching corps was difficult to gnaw, and they also learned to be obedient, and treated them in the same way. A small number of troops were also left to contain the teaching corps, and concentrated their forces to attack the engineer school defended by the 87th Division on the flank, and one battalion of the defenders could not resist and retreated into the city. The Japanese army occupied the engineering school and suddenly broke into the Guanghua Gate.

At this time, Wang Jingzhi, the commander of the 87th Division, was squatting in the basement of Fugui Mountain, without a staff adjutant by his side, and he was smoking a cigarette with his head bowed. When the news of the loss of the sapper school came, he jumped up, threw away his cigarette, and was speechless for a long time.

"Senior Commander Wang, I'm afraid this situation should be reported to the commander as soon as possible!" Qiu Qingquan, chief of staff of the teaching corps next to him, reminded him.

Wang Jingzhi woke up this time like a dream and hung up the phone of the commander's management department, and as soon as the engineering school was lost, the Guanghua Gate of Nanjing City was the first to be exposed to the Japanese army. What Wang Jingzhi heard on the phone was Tang Shengzhi's scolding. As soon as he put down the phone, he didn't call anywhere, and shouted to the 260 Brigade Headquarters on the phone: "Tell Brigade Commander Liu to come to see me immediately!" ”

After a while, Liu Qixiong, the brigade commander wearing a gray cotton military uniform and a soldier's belt, arrived.

"Why did you lose the sapper school!" Wang Jingzhi asked.

"We have retreated from Shanghai, and half of the people have not been accommodated, and in addition to the hard fighting in the past few days, many officers and men have been injured either dead or wounded, and there are actually only more than one company of the Engineer School, so we ......," Liu Qixiong replied unhurriedly.

"Go back! Organize the rest of the people and wait for orders. In fact, Wang Jingzhi is also clear about these situations, what else can he say? What kind of order did he listen to, Wang Jingzhi didn't say, in fact, he didn't know it himself.

The Japanese troops attacking Guanghua Gate pushed out the mountain artillery and bombarded the city gate, and the city gate was torn down, and the mud and sand in the wall immediately poured out...... Then hundreds of tanks and tanks pressed against the position...... The Chinese soldiers guarding Guanghua Gate almost used suicidal fighting methods to die along with the Japanese tanks and tanks. On the position, tanks and tanks collapsed together in wailing. More than 1,000 Japanese soldiers climbed up with the 38 big covers, and the officers and soldiers of the defenders raised their bayonets to meet them, and the sound of swords and swords on the city wall shook the sky.

Lin Feng's special combat team has always been stuck to Guanghuamen, and Tang Xinzhi gave a death order: people are in the position! At the critical moment, when Lin Feng led the Falcon Special Team and the teaching team guarding Guanghua Gate to penetrate the chest of the last Japanese soldier with bloody bayonets, hundreds of Japanese corpses and thousands of Chinese soldiers' corpses lay up and down the city wall.

The fighting intensified. Guanghuamen was repeatedly broken through by the Japanese army, and the commander's department urgently ordered the 156th Division to reinforce Tongjimen and plug the gap in Guanghuamen. Deputy Commander Liu Xing personally went to the front line to command, and the gap was finally blocked. The officers and soldiers had just breathed a sigh of relief, when suddenly a burst of gunfire rang out, and the guard post on the city wall fell to the ground in response. Strangely, this shot did not come from below, but from under the city walls.

It turned out that a group of Japanese soldiers hid in the hole in the city gate, and the defenders' firepower was out of reach, and they couldn't blow up the grenades thrown down. The enemy, however, could kill and wound the defenders on the walls from concealment. It was getting dark, and the officers and soldiers defending the city were so anxious that they were at a loss. I don't know who said: "Burn these turtle grandchildren!" ”

Yes! Everyone gathered gasoline and poured it down the city wall to the entrance of the door. Then, dozens of daredevils quietly hung ropes around their waists and landed on the city walls, a gust of grenades ignited gasoline, and the enemy in the city gate cave burned and screamed in the flames, and no one survived.

The task was completed, but these dozens of warriors did not climb the rope, they had already held the belief that they would die, and pounced on the Japanese troops reinforced by the Tongguang barracks outside the city, and beat the Japanese soldiers with their heads in their hands. The warriors rushed bravely, and finally all fell to the ground outside the Guanghu Gate.

After the Japanese failed in attacking Gwanghwamen and Tongjimen, on the 11th, the 6th Division of the elite troops Tani Shofu and the 114th Division of Shigeharu Suehua stormed Yuhuadae and Zhonghuamen. Deputy Commander Luo Zhuoying's husband commanded the first line, and engaged in fierce street battles with the Japanese army in the area of Zhonghua Gate, and wiped out all the enemies who broke into the city.

From 7 o'clock in the morning, Japanese planes, artillery, and tanks bombed the Yuhuatai position, which was less than 2,000 meters wide, and the Japanese troops of the two wings repeatedly attacked. After 3 days of fierce fighting, thousands of Japanese soldiers were left dead in front of the battle. The 88th Division of Sun Yuanliang's Chinese defenders also paid a huge price, and more than 6,000 officers and soldiers below the commander of the 262nd Brigade Zhu Chi and the commander of the 164th Brigade Gao Zhisong were all martyred.

On December 12th, from dawn, Japanese planes and artillery intensively bombarded the city gates, the ancient and strong city walls were blown up to the ground, the buildings around the city walls collapsed, the city walls were opened, and the defenders in the city could clearly see the steel helmets of the Japanese soldiers.

At 12 noon, Yuhuatai was occupied by the Japanese army; The second peak of the Purple Mountain also fell; The 2nd Army Corps was forced by the Japanese Kunisaki detachment to the riverside from Oolong Mountain to Kichijoan, and there was no way back. Many of the cities at Zhonghua Gate and Zhongshan Gate were destroyed by Japanese artillery fire, and Japanese troops poured in like a tide through the gaps in the city wall and overflowed into the city. Hundreds of Chinese soldiers, who were killed in battle and had no one to command, spontaneously met the enemy and used their bodies to block the enemy.

Guanghuamen remained firmly in the hands of the Chinese defenders.

The Falcon Special Combat Team led by Lin Feng also lost more than half of the battle to defend Guanghua Gate, and all the shadow units of the Japanese army were wiped out.
