The original name of the Engineer School, the Army Engineer School, was a school founded by the chairman of the National People's Congress to train military talents, but now this school has no students, and the school has completed the relocation long before the Japanese army attacked Nanjing.

This school is not far from Guanghua Gate, in the middle of Guanghua Gate and Gaoqiao Gate, at this moment stationed in the engineering school is our army's 87th Division, 260 Brigade, the brigade commander is called Huang Guang.

The terrain of the engineering school is relatively complicated, because there are more buildings inside, so there are more bunkers, which makes it easy to build a military engineering palace, and it is a serious place that is easy to defend and difficult to attack, as long as the building is guarded and the high ground is occupied, it is difficult for the Japanese army to enter.

However, the Japanese army apparently had been prepared for this for a long time, and the construction of an artillery point at Gaoqiaomen was specifically for the Great Engineer School.

At nine o'clock in the morning, the battle began.

The method adopted by the Japanese army was still the same as before, first let the artillery regiment of Takahashimon open fire with all their might, destroy more than half of our army's defenses in advance, and then launch an attack.

This set, although old, does use, an artillery regiment, about a hundred and ten guns, these guns fired at the same time, directly covering the engineering school.

100 cannons, 100 shells exploded at the same time, this phenomenon is very shocking, every time the shelling, the ground of Nanjing City will shake, like a small earthquake.

After the first round of shelling, one-third of the fortifications built in the engineering school were destroyed in an instant, and one-third of the machine-gun and artillery points built on the high ground were also scattered.

After the second round of shelling, half of the fortifications in the engineering school were destroyed, and as many as half of the strongholds on the high ground were also destroyed.

After the third round of shelling, only about a fifth of the fortifications in the engineering school remained, and only about a fifth of the strongholds on the high ground remained, and most of the soldiers hid in the buildings to hide from the artillery fire, and there were no personnel left at the front line.

Three rounds of artillery fire, more than three hundred shells, what is this concept?

After the artillery fire, the land in the engineering school was full of big pits, black smoke was rising everywhere in the school, and in some places there were still raging fires, one-fifth of the buildings collapsed, more than half of the buildings were damaged, and five-sixths of the buildings had cracks in their walls.

Of the more than 3,000 soldiers of the 260 Brigade, at least 500 of whom were buried in the fire, most of them were buried in collapsed buildings.

Three rounds of artillery fire, but it took only fifteen minutes, there was no more defensive stronghold in the engineering school, and the morale of the soldiers of the 260 Brigade was also half blown away.

Suppression, real all-round suppression!

After three rounds of artillery bombardment, the Japanese army directly entered the field, and the Japanese lieutenant general who led the team was very level, he first let the scouts move forward, and then let the machine gunners occupy the high ground first, and then followed by the infantry to advance forward, and the fight was very layered and rhythmic.

In the shelling of the 260 Brigade just now, there were too many casualties among the grassroots officers, which led to the untimely transmission of the combat order, and the morale was a little low, for various reasons, the 260 Brigade blocked for less than an hour, and the brigade commander Huang Guang had no choice but to order the withdrawal of the troops.

At ten o'clock in the morning, the sappers announced the high break!

Under the attack of the Japanese army at all costs, the most difficult engineer school was taken in an hour, which greatly boosted the morale of the Japanese army.

The defensive positions of the Teaching Corps were in the same situation as those of the Engineer School, which was broken through even earlier than the Engineer School, and the two places, which were supposed to watch over each other, were now the first to be breached.

At about one o'clock in the afternoon, a fierce battle also broke out at the inner city gate of Nanjing, and the Japanese army mobilized a large number of tanks and artillery to launch a fierce attack on the inner city gate.

Because the firepower of the Japanese army was too fierce, the guards did not dare to let the Japanese army bombard indiscriminately, and if the city wall was breached, the city of Nanjing would definitely be lost.

Therefore, the defenders still adopted the most primitive method, which was to charge with manpower, break through the Japanese positions, destroy the Japanese tanks, and thus contain the Japanese firepower.

In the afternoon, the Japanese army was scattered three times, and organized three attacks, although it cost the lives of countless soldiers, but when the Japanese army attacked for the third time, after all, the city gate was broken, although the defenders fought back desperately, but there were still more than 500 Japanese troops, taking the opportunity to enter the city of Nanjing, temporarily lurking.

After the Japanese army broke through the Engineer School, they continued to advance inward, preparing to attack Guanghuamen in the inner city of Nanjing.

The garrison headquarters urgently ordered the military police at Qingliangshan to teach the reserve of the 2nd Regiment to reinforce Guanghuamen, and at the same time ordered the 87th Division to counterattack.

Chen Ding, deputy commander of the 87th Division, commanded the 1st Brigade of the 261st Brigade and part of the 259th Brigade to carry out a combined attack on the enemy's flank from Tongjimen and Tiantian Village.

On the other side, the Japanese 10th Division attacked Dangtu at about 5 p.m., and the defenders of Dangtu resisted fiercely, and after four hours of fierce fighting between the two sides, the Japanese army officially occupied Dangtu.

One day, another whole day of fierce fighting, the city of Nanjing became completely isolated and surrounded by Japanese legions.

On December 9 alone, according to incomplete statistics, our army suffered more than 10,000 casualties, more than 6,000 serious wounds, and countless minor wounds.

Panic, fear, hung over Nanjing.

At the same time, Linyi, on a certain road.

Six military vehicles opened the road, and behind the military vehicles, about a thousand soldiers were hurrying non-stop, these soldiers looked unkempt, and most of them had chapped lips.

This group of people is none other than Zheng Long and others.

Six days, 1,200 kilometers, starting from Baoding, passing through Cangzhou, Dezhou, Jinan and other places, and now finally arrived in Linyi, about 400 kilometers away from Nanjing.

There was no boat, and he also carried a lot of supplies, so the waterway could not be walked, Zheng Long could only lead the soldiers to take the dirt road, there was no train, there was no means of transportation, and everyone came on foot all the way.

Two hundred kilometers a day, more than a thousand kilometers in six days, the soldiers' shoes were changed several times, and blood blisters were felt on everyone's feet, but none of these fighters complained, and everyone was holding their breath in their hearts.

Zheng Long, Lu Zizheng, Fair, Xie Jin and these people could have taken the car, but they insisted on walking, personally took the lead in demonstrating for the soldiers, and when they were resting, Zheng Long and others also deliberately enlightened the psychology of the soldiers, and it was under the leadership of Zheng Long and others that these soldiers became more and more calm and capable.

"Hurry up! It's all about to fall! Let's rest another 20 kilometers! Keep it up, brothers! Zheng Long kept urging.

"Yes!" Although the soldiers were tired, they still shouted at the neck.

The last 400 kilometers, you must catch up!

Zheng Long kept praying and praying!
