Jiangyin Fortress has an excellent geographical location. It is located at the throat of the bell mouth in the lower reaches of the Yangtze River, and has been a battleground for soldiers since ancient times. The Yangtze River thus becomes open to the east, and the Huangshan Fort is located on the bank of the Yangtze River on the south side. The Huangshan Fort is located in the narrow part of the river, known as "the gateway of the river and the sea, the fortress of locking navigation". The ancient fort of Huangshan has a long history, and at present, the national government has built 12 reinforced concrete fortresses on the basis of the ancient fort in the core area of the fort of Huangshan.

Li Dabao was well versed in the internal situation of the battery group, and the Japanese army was heavily guarded, so it was impossible to sneak attack, so he could only launch a strong attack. After the Japanese occupied the fortress battery, they did not immediately blow up the artillery, but used the fortress artillery to cover the safe evacuation of the Yangtze River fleet. There are Japanese sandbags on the pier, and there are 3 Japanese soldiers in the fortifications. On the decks of the two gunboats, there were also Japanese sentries, and there was no one at the machine guns on the gunboats, apparently the Japanese gunners were resting in the cabins. At 10 o'clock, two red flares rose in the sky on the east and south sides of the fortress.

Li Dabao gave the order to open fire, and the snipers first aimed at the locked target, and with a few crisp gunshots, three Japanese machine gunners in the dock fortifications were killed, as were the Japanese sentries on the deck of the gunboat. The Japanese reacted very quickly, and saw the Japanese gunners quickly running out of the cabin and rushing to the gun position. Li Dabao deployed 8 snipers to lock on to the gunboat, and with accurate shooting, the Japanese gunners were knocked to the ground before they could run to the gun position. The Japanese soon sensed that there were snipers on the other side, and the two gunboats, including the transport ship, immediately moved and slowly fled from the dock.

At this time, a rocket hit the wheelhouse of a gunboat, and with a violent explosion, the gunboat's wheelhouse fragments flew sideways in the flames of the explosion, and everyone was immediately ablazed. The gunboat had just left the dock when the gunboat lost control and collided with the transports next to it due to a hit in the cockpit. At this time, a group of Japanese soldiers rushed out of the fortress walls, and their machine guns immediately opened fire, and the Japanese soldiers who were beaten turned on their backs and quickly retreated.

Just as Ouyang Jian judged, the Japanese army really dispatched three squadrons of soldiers from Shanghai. At this time, the captain of the Japanese army stood at the opening of the fort wall to observe, and one of his subordinates said: "Your Excellency, the enemy's firepower is fierce and the soldiers are well-trained, and it may be the enemy's special combat unit!" The captain of the brigade, whose name was Nakamura Masao, put down the binoculars at this time and said: "Judging from the offensive situation, the enemy is strong in combat and the enemy intends to recapture the fort, so we must hold out until tomorrow morning." Shanghai is calling, the Yangtze River fleet will arrive tomorrow morning. ”

Nakamura Masao knew in his heart that this enemy force was not good, and I was afraid that it would be a vicious battle. "Your Excellency, the enemy is attacking!" In the dark, Nakamura Masao found that the enemy was advancing in a skirmish line, and he was moving quickly and agilely. Looking up at the river, he saw that two gunboats and a transport ship were already located in the middle of the river, "Order gunboat fire support to delay the enemy's attack!" "It was reported that the enemy attacked simultaneously from three directions, but there were not many troops, and judging by the enemy situation, the strength of the troops would not exceed one battalion."

The guns roared, and the gunboats in Jiangxin kept firing, and the explosion was deafening. All three squadrons of the Japanese army were thrown into battle. The Japanese soldiers guarding the walls were constantly being hit and fell, and Nakamura knew that he had met a real opponent. At this moment, a rocket accurately hit a machine-gun position, and with the fire of the explosion, the two machine gunners were lifted by the air wave. The machine-gun position was less than 10 meters from Nakamura's command position, and Nakamura got up from the ground to see that the two machine gunners had been killed.

"Order the grenadiers, take out the enemy gunners!" Masao Nakamura roared. Several Japanese grenadiers immediately rushed to the battlement and fired. On the attacking side, "reported to the captain, the 6th group of bazooka players was killed, and two secondary shooters were wounded. "Order the grenadiers to suppress the Japanese grenadiers!" Suddenly, several grenadier rounds flew towards the battlement. After a round of exploratory attacks, Li Dabao basically figured out the strength of the Japanese army, and it can be concluded that the strength of the Japanese army is three squadrons.

"Order the reserves to be transferred to the south gate immediately, and order the 4th, 5th, and 6th detachments to launch a strong attack!" Li Dabao gave the order. As the 10th Reserve Brigade moved to the south gate, the fire from the south suddenly became fierce. "Report, the Japanese gunboats are firing fiercely, and the 1st and 3rd detachments have suffered casualties of varying degrees!" It was a brutal battle in itself, and casualties were inevitable. Li Dabao's expression was solemn and he turned his attention to the south gate. If the Jiangyin fortress cannot be taken before dawn, and the Yangtze River fleet arrives after dawn, it means that the battle plan has failed.

At the south gate, the machine guns formed crossfire, and with the cooperation of bazookas and grenadiers, the Japanese machine guns were suppressed. The demolition team quickly made a detour back to the door with the explosives bag in their pockets. I saw a flash of firelight, and with a loud bang, the gate disappeared. Before the smoke of the explosion had cleared, the assault team attacked. The Japanese army did not collapse because the city gate was blown open, and they still fought stubbornly.

Just after the attack began, the National Army units located in the rear of the western flank were alarmed. The soldiers of the national army looked in the direction of the fortress one after another, "Battalion commander, it is possible that the communist guerrillas attacked the fortress, what should we do?" The battalion commander of the national army rolled his eyes and said: "Let them fight first, and then we will shoot when the fight is almost done." "Battalion Commander Takami, did you go out to investigate?" "Send out a squad and find out the number of guerrillas." The nervousness of the soldiers relaxed, and most of them lay down on the spot.

As soon as the assault team rushed into the city gate hole, they were confronted by a counterattacking Japanese army. The commandos who rushed to the front, each armed with a submachine gun. Under the dense rain of bullets, the counterattacking Japanese troops could not parry. The assault team entered the fortifications and was met with more stubborn resistance from the Japanese. The Japanese soldiers used various terrain to block the attack, and a wounded Japanese soldier lying on the ground saw two commandos passing by, and did not hesitate to pull the grenade on his body. With the sound of explosions, two commandos collapsed in a pool of blood.

Several commandos stormed a fort, and several Japanese soldiers were knocked to the ground under the fire of submachine guns. Suddenly, a Japanese soldier jumped out of the shadows, covered with grenades. One of the team members was in a hurry, and a point shot knocked down the devil, and everyone quickly lay on the ground, but the grenade did not explode. "Fuck, little devil, this is going to die together! Everyone should be extra careful and not have a trace of pity. ”

At about one o'clock in the morning, as the south was breached, so was the east and west sides. Li Dabao entered the fort group, and a subordinate reported, "Report to the captain, the Japanese army is currently cowering in the four central forts. According to preliminary statistics, 123 Japanese soldiers were wiped out, and many wounded Japanese soldiers were still resisting at the last moment, and none of them survived. Our casualties are also very serious・・・・・・ Li Dabao took out his pocket watch and glanced at it and said, "Order all detachments to end the battle before 3 o'clock." ”

At this time, the commander of the Japanese army, Nakamura Masao, cowered in a fortress. Two squadron leaders have been killed, and only one squadron leader remains. Soon after the battle began, he figured out what was going on with his opponent. Although the opponent is not dressed, it is certain that the special combat team of the national army. According to the information he had, the army of the Nationalist Government was not equipped with such advanced weapons at all. When the enemy all stormed into the fort group, Nakamura Masao ordered a final telegram to be sent to Shanghai, and all the jade was shattered.

After the radio station was smashed, the telegraph operator reported that the Shanghai side had dispatched warships and reinforcements, and that the air force would be dispatched to support it after dawn. Nakamura Masao knew in his heart that it would take 4 hours to reach Jiangyin from Shanghai against the water. 4 hours, given the strong combat power of the opponent, it is simply impossible to hold on for 4 hours. At this time, the Japanese gunboats on the river had stopped shelling, probably for fear of accidentally injuring their own people. The enemy is attacking again, and Nakamura Masao closes his eyes and remains calm.

At the height of the battle, the battalion commander of the Nationalist Army received a report from the scouts that it was not the guerrillas who attacked the fortified fort but the Nationalist army. They have advanced weapons and equipment, strong combat effectiveness, and have now attacked the south gate. There are about 200 troops on the west and south sides, and the situation on the east side is unknown. The battalion commander of the national army knew what the strength of the Japanese army was, and the fortress artillery who escaped from the Jiangyin fortress had already informed the situation. According to the analysis of the battalion commander of the national army, the artillery group will be attacked in three directions, with 200 troops on the west and south sides, and there will not be too many troops on the east side.

Obediently, it is unimaginable that the strength of one battalion actually launched an attack on three Japanese squadrons defending the fortress. When he set out, the regimental commander specifically instructed him that he must wait for the whole regiment to arrive at the fortress before launching an attack. And this sturdy force, with only three or four hundred men, actually wanted to take the battery group. Not only that, but in less than two hours, it actually broke through, and the combat effectiveness of this army was too strong. The battalion commander had no idea, so he had to send someone to quickly turn back to the regiment commander to report.

As the battle came to an end, Li Dabao walked into the fortress. I saw four or five Japanese soldiers surrounding Nakamura Masao to make a final resistance. Li Dabao waved his hand, and several gunshots rang out, and the surrounding Japanese soldiers were shot and fell to the ground. "Put down your arms, shoot or kill!" Li Dabao said majestically. "I wonder who you are?" "We are the Eighth Route Army Navy Special Operations Team!" Masao Nakamura got the answer and did not hesitate to put the gun at his head.

Li Dabao walked out of the fortress and said to his subordinates: "Clean the battlefield immediately and check the artillery situation of the fortress." Soon after, casualties were reported, 45 killed, 32 seriously wounded, and 55 lightly wounded. Li Dabao instructed that the fallen brothers should be buried on the spot at the foot of the Yellow Mountain, and their heroic souls would continue to guard the fort. An hour later, Li Dabao received a telegram from the dark arrow that the Japanese Yangtze River Fleet had reached Zhenjiang, and that Japanese reinforcements from Shanghai had also arrived in Zhangjiagang.
