As soon as the plan of action was conveyed in the form of an order, the units began to operate, and the troops that had gone to the south gate in concealment were led by several reconnaissance detachments to clear them of obstacles on the road. Because it was a covert advance, the troops made a circle, and they had to avoid the eyes and ears of the Japanese army, and only approached the south gate of Yueyang City after two hours. According to the observation of the reconnaissance detachment, on the wall of the south gate of Yueyang City, there was only one Japanese squadron stationed, with four mortars, two Type 92 infantry guns and four 37-caliber rapid-fire guns.

In order to prevent the Japanese army from seeing the flaws, the tank vehicles were still bombarding the Japanese troops on the city wall during the feint, and even blew up the east gate, which made the Japanese army very nervous and desperately fought back regardless of the casualties.

Finally, after Li Yuanhong, who was in charge of the command at the south gate, sent a telegram that he had successfully sneaked to the vicinity of the south gate, the Japanese army's south gate was weakly guarded, and the operation could start, Tang Renxin breathed a sigh of relief, the most critical part of the plan had been completed, and it was up to Li Yuanhong to play it. Tang Renxin looked at his watch, it was already 9:20 a.m., Tang Renxin sent a telegram to Li Yuanhong, and it was scheduled to launch an attack on Yueyang City in two directions at 9:30 a.m. at the same time.

After sending the telegram to Li Yuanhong, Tang Renxin asked Tangshan Leopard and his guard regiment to also prepare for the attack. At 9:30, the attacking force, consisting of 12 Cheetah heavy tanks and 18 Type 62 light tanks, launched its largest attack on Yueyang City. Dozens of steel behemoths charged forward, giving people the feeling of being terrifying.

The commander of the 38th Infantry Brigade of the Japanese army at the head of the city, Aono Saburo Osa, saw that the Shina army outside the city had mobilized a large number of chariots to attack, and he also became nervous and hurriedly called for artillery support. Soon after, the mountain artillery brigade in the city began to shell the besieging tanks. The charge launched by the tank looked fierce, but the armored vehicles and the regiment of the guard brigade behind were all ready to attack and did not follow the tank to charge.

At the same time, the troops outside the south gate were led by the heavy tank battalion, the light tank battalion and the armored battalion followed closely, and the 1st and 2nd battalions of the 2nd Guards Brigade Regiment also followed the armored battalion and launched an attack on the south gate at the same time. The 3rd Guards Regiment set up artillery positions, bringing 24 120 heavy mortars and 30 100 100 mortar guns aimed at the south gate.

The roar of the chariot engine alarmed the Japanese troops guarding the city wall at the south gate, and the Japanese squadron leader in charge of the command lay on the city wall in surprise and looked in the direction where the sound came from. This frightened him, and in the distance smoke and dust flew up, and in the smoke and dust, he could see chariots roaring towards him. The squadron leader screamed: "The enemy is attacking! The Chinese chariot is attacking!" The changed tone of the voice made the Japanese troops on the city rush into the position, and several small cannons on the city were also ready to fire.

When the tank was still 800 meters away from the city wall, all kinds of small cannons opened fire on the city. The shells landed on and around the attacking tanks, causing little damage to the tanks, except for the clanging of the tank's armor. Ignoring the presence of these shells, the tanks approached directly. And at this time, the mortars of the 3rd Guards Regiment fired, and dense mortar shells flew towards the city.

The city was suddenly plunged into a burst of artillery fire, and the dense artillery fire easily destroyed these small cannons on the city, and the Japanese army suffered heavy casualties. The squadron leader of the command was also wounded. In the midst of the artillery fire, the squadron leader struggled to find the telephone, reported to the brigade headquarters that the south of the city was attacked by a large number of tanks and artillery of the Chinese people, and asked the brigade commander to quickly send troops to reinforce the south gate.

The brigade commander, Major General Kenyoshi Ikegami, was startled by the sound of gunfire coming from the south gate when the squadron leader's phone called. Major General Kenkichi Ikegami scolded a few words: "Yaga!" and immediately ordered the 39th Infantry Brigade to quickly reinforce the south gate. It's just that when the 39th Infantry Brigade received the order, and the captain of the brigade, Tsunahiko Yasue, personally led the team, it was already too late.

Outside the south gate, the 3rd Regiment of the Guard Brigade blew up the Japanese troops on the city with a burst of artillery fire, and the tank vehicles took the opportunity to approach the city wall, and a few artillery bombarded open the south gate. As soon as the city gate was blasted open, the tanks dodged a passage and opened artillery cover on both sides of the passage. The armored vehicles behind and the 1st and 2nd Battalions of the 2nd Guards Regiment quickly moved forward and went straight to the city gate that had been blasted open.

There are still some Japanese troops in the city gate cave using sandbag fortifications, trying to prevent the troops from entering the city, rushing to the front of the four heavy armored vehicles, with a vehicle-mounted 20 mm caliber tank gun against the sandbag fortifications is a cannon fire, coupled with the heavy machine gun fire on the car, the few Japanese troops in the city gate cave suddenly collapsed, and the few surviving Japanese soldiers quickly fled to the city to report the news.

As soon as Yasue Tsuyohiko Osaku approached the south gate with the 39th Infantry Brigade, he encountered the defeated Japanese soldiers, Yasue Tsuyohiko Osaku grabbed the collar of a military cao, stretched out his hand and gave him two slaps, and then chased the south gate after the fight. After being slapped twice, the soldier came to his senses, and after standing upright, he reported to Yasue Tsuyohiko that the south gate had been lost, and that the chariots and soldiers of the people of China had rushed into the south gate.

Takeshi Yasue was taken aback, and while sending people back to report to the brigade commander, Major General Kenkichi Ikegami, he ordered the 39th team to defend on the spot. The first battalion of the 2nd Guards Regiment followed the armored vehicles to continue the assault into the city, while the 2nd Battalion climbed to the top of the city to clear out the remnants of the enemy. After clearing the remnants of the enemy, a signal was sent to the outside of the city, and the 3rd Guard Regiment and 3rd Guard Regiment outside the city all rushed into the city.

Li Yuanhong set up a temporary headquarters at the head of the South Gate, leaving the Second Battalion of the Second Guard Regiment to defend at the head of the city, and the rest of the troops cooperated with armored vehicles to attack the city, and at the same time sent a telegram to Tang Renxin, informing him that the South Gate had been taken by himself and that the troops were attacking the city. The troops attacking the city did not penetrate far before they encountered the 39th Infantry Brigade, which was blocking the attack. The 39th Infantry Brigade occupied buildings on both sides of the road into the city, and obstacles were erected in the middle of the streets to make temporary bunkers.

The attacking troops used light armored vehicles as the main force of the assault, the chariot guns on the heavy armored vehicles as supporting firepower, and the fighters in the hands of rocket launchers and 82 recoilless guns such as sharp weapons, the 39th Brigade's blocking did not cause much trouble to the attacking troops. The troops advanced slowly but firmly, and there were also light armoured vehicles that were wounded and blown up by explosive packs or cluster grenades thrown from streetside buildings, but the losses were limited under the cover of experienced Guards Regiment fighters.

As soon as the south gate was lost, the Japanese troops in the city panicked, and Tang Renxin, who attacked the east gate, knew that Li Yuanhong's troops had captured the south gate, so he suddenly exerted his strength, and the armored vehicles and the first regiment of guards pressed on the whole regiment and carried out a strong attack on the east gate. The Japanese army at the head of the East Gate City was already struggling to support, and at this time, the siege troops suddenly exerted force, and they couldn't bear it.

In this assault, the first regiment of guards cooperated with armored vehicles to take the east gate at a small price, and then took advantage of the situation to attack the city. Major General Kenyoshi Ikegami, the commander of the 9th Brigade, learned that the East Gate had also been broken through by the Shina army, and knew that the general situation was gone, and hurried to the headquarters of the 11th Army. The sound of gunfire at the two city gates had made the commanders of Anan Weiji's face pale, and he was reported by Major General Kenji Chishang that the east gate and the south gate were lost, and Yueyang City could no longer defend the news, and suddenly his heart hurt, and a mouthful of old blood spurted out, and he fainted.

The chief of staff, Major General Isamu Kinoshita, hurriedly called for the medical personnel, and then carried the unconscious commander Anan Weiji, under the protection of the military police brigade, and left Yueyang City from the west gate. The headquarters of the Eleventh Army hastily evacuated Yueyang City, and only the remnants of the Independent Mixed Ninth Brigade and some baggage and engineering units remained in Yueyang City. Major General Kenyoshi Ikegami also did not hesitate to save his life in order to cover the evacuation of the headquarters of the 11th Army.

Major General Kenyoshi Ikegami put the 40th Infantry Brigade at the headquarters of the 11th Army, and relied on the three-story building of the headquarters to make a last-ditch effort. At the same time, as long as the Japanese soldiers in the city could hold guns, they were organized and scattered around the headquarters, and the independent artillery brigade was also dispersed and defended with the infantry, and at the same time ordered several other infantry brigades in the city to retreat to the headquarters while blocking the attack. It's just that there aren't many soldiers left who can withdraw to the periphery of the headquarters.

When the attacking troops were attacking, the resistance suddenly became smaller, and both Tangshan Leopard and Li Yuanhong found that the Japanese army was retreating towards the center of the city. The reconnaissance detachments that had entered the city reported to the two units that the Japanese were concentrating on the headquarters of the 11th Army and might hold on to the headquarters of the 11th Army. At the same time as receiving the report of the reconnaissance detachment, Tang Renxin also received a telegram from Wang Haitao.

Wang Haitao's telegram was to ask Tang Renxin how the siege was progressing. The second is to inform Tang Renxin that the main force of the 11th Army of the Japanese army is going all out to return to Yueyang City to block the two armies of the Japanese 27th Group Army.

Tang Renxin pondered for a long time in the face of the two pieces of information, and sent a telegram back to Wang Haitao, reporting that Wang Haitao's troops had entered Yueyang City and were besieging the last stubborn Japanese army. He promised to take down the recalcitrant Japanese army within 24 hours and occupy all of Yueyang City.

Soon Wang Haitao's reply arrived, and in the telegram, Wang Haitao agreed to give Tang Renxin 24 hours for the attack, but told Tang Renxin that first, after capturing Yueyang City, he would immediately organize a defense to prevent the main force of the Japanese army from counterattacking Yueyang City, and second, he would give full play to the superiority in weapons in the offensive to minimize casualties and losses of chariots.

Tang Renxin read Wang Haitao's reply, and immediately ordered Li Yuanhong and Tangshan Leopard to attack the blocking army, and to take the Japanese army within 12 hours while minimizing losses. Tang Renxin's place only gave the two of them twelve hours, that was because after capturing Yueyang City, it still needed time to organize defense, and the troops had been attacking for such a long time, so they had to take a rest.
