The Type 92 infantry guns and mortars of the Japanese infantry wing were all curved guns, and when bombarding the main position of Gaoziling from the bottom of the mountain, the shells could accurately fall on the fortifications and trenches, but when the attacking infantry fired from the bottom up, the accuracy was much worse. However, along the way of the attack, there were many places that could be used for cover, and the quality of the Japanese individual soldiers was generally high, so it was not so easy for the defenders on the position to hit the attacking Japanese soldiers.

In the face of such an attack, the defenders' most powerful weapon was not a machine gun, but a grenade. Condescendingly, grenades can be thrown almost halfway up the mountain, so most of the casualties of the defenders on the position came from the Japanese shelling, and the casualties of the Japanese soldiers were due to the large number of grenades thrown by the defenders. After the defenders repulsed the two attacks, the Japanese army changed its attack method, no longer attacking with brigade-level infantry groups, but sending one squadron at a time, and then dispersed into battle groups and scattered to infiltrate the mountains.

In this way, because of the small number of people and the dispersion of troops, the power of the defenders' grenades was greatly reduced, and they had to increase the strength of the first line and use the numerical advantage to block the Japanese attack, and the personnel on the first line were dense, and the threat of Japanese artillery fire was greater.

When Chen Jijian, commander of the 60th Division, learned of the situation, he immediately ordered the three regiments hidden on the anticline of the position to support the main position in turn, so as to block the Japanese attack. The casualties of the 23rd Wing of the 6th Division of the Japanese Army in the morning were not small, the most important thing was to attack on the back like this, the physical exertion of the soldiers was too great, looking at the tired subordinates, the 23rd Wing Wing Commander Dazuo also wanted his subordinates to rest and recover some physical strength before attacking.

Unlike the 37th Army, the two divisions of the 53rd Army were originally transferred from Wang Haitao's 90th Army, and their weapons and equipment were not a little stronger than those of other units. When the 40th Division of the Japanese Army arrived at Chunhua Mountain, it faced the 92nd Division of the 53rd Army, which was waiting for battle.

On the morning of January 3, the 235th Infantry Wing of the 40th Division was ready to attack, but when the Japanese began to bombard the defenders' positions with artillery fire, they were counterattacked by the defenders' artillery. Before the 92nd Division was separated from the 90th Army, Wang Haitao equipped the 12th Division with a heavy artillery regiment, equipped with 12 Japanese 120-mm heavy cannons and 16 Japanese 75-caliber field guns captured in Anqing. In addition, like other divisions of the 90th Army, mortars were equipped from the company level.

At this time, the artillery fire of the 92nd Division's counterattack gave the 235th Infantry Wing of the 40th Division a disadvantage. The 40th Division had never encountered a large-scale artillery bombardment by the Chinese army for so many days since it began its offensive, and the unsuspecting Japanese troops suffered a loss at this moment; not only were the Type 92 infantry guns and mortars in the wing completely destroyed, but the heavy machine-gun positions and an infantry brigade that was preparing for the attack were also blown up by the artillery of the 92nd Division.

At this time, the Japanese army could not attack, and when the situation was reported to the division commander, Lieutenant General Aoki Seiichi, Lieutenant General Aoki Seiichi was taken aback and hurriedly ordered the 40th Wing of the Mountain Artillery to set up an artillery position forward, and it was necessary to destroy the artillery position of the Shina army. The commander of the 40th Wing of the Mountain Artillery, Shiraishi Kuyasu Osa, who received the order, felt helpless for a while, this has no direction, no coordinates, God knows where the artillery position of the Chinese people is? How can he destroy the artillery position of the Chinese people?

In order to fulfill the order of the division commander, Shiraishi Kuyasu had no choice but to consult with the commander of the 235th Infantry Wing, who was preparing to continue the attack, and let the 235th Infantry Wing launch an attack first, and after the artillery bombardment of the Shina people, the artillery of the Mountain Artillery Wing would counterattack. When Nishina Xin Dasa heard it, this was also a helpless move, and it was the only way to achieve victory. So Nishina Shin Daisa ordered an infantry brigade to attack the defenders' positions.

Chunhua Mountain is relatively high in these small hills northwest of Changsha, reaching 210 meters, and other dirt hills are different from other earth hills, Chunhua Mountain is a granite-dominated rock mountain, although it is not easy to build a position, but the defensive capability is also very strong, the 92nd Division took a lot of effort to build a defensive position in several suitable positions in Chunhua Mountain.

With the experience of fighting behind Wang Haitao, the standard of fortification repairs of the 92nd and 91st Divisions was also very high, not only digging trenches, communication trenches, anti-artillery holes and other artificial fortifications, but also making use of some natural terrain types, such as several caves turned into heavy machine gun bunkers and ammunition depots, and several depressions became headquarters and hiding places.

The 92nd Division built a total of three lines of defense from the mountainside to the top of the mountain, increasing the depth of defense as much as possible, which was also repeatedly emphasized by Wang Haitao during the 90th Army, and it was also tested in battle. In the deployment of troops, the principle of giving priority to the front and emphasizing the latter advocated by Wang Haitao is also used. Only two battalions were deployed on the first line.

The two battalions of the 92nd Division have a strength of 1,000 men, which is almost equivalent to a regiment compared to other divisions, and these two battalions not only have semi-automatic rifles and submachine guns in the hands of the soldiers, but also have a light machine gun at the squad level and a heavy machine gun at the platoon level. Moreover, the battalion has a heavy firepower company, equipped with mortars, heavy machine guns, Type 82 recoilless guns and other heavy weapons.

This time, when Wang Haitao arrived in Changsha City, Guo Rudong, commander of the 53rd Army, personally went to see Wang Haitao and asked Wang Haitao for help, asking Wang Haitao to help him with a batch of ammunition for the sake of his old subordinates. Wang Haitao naturally did not treat these old subordinates badly, not only gave a lot of ammunition, but also gave Guo Rudong a batch of guns to make up for the part of the guns lost in the past two years. Wang Haitao's selfless support made Guo Rudong more confident, so the 53rd Army, which was full of strength, fought against the 40th Division of the Japanese Army in Chunhua Mountain.

An infantry battalion of the 235th Infantry Wing of the Japanese Army, without artillery cover, launched an attack on Chunhua Mountain. An infantry brigade, and there is no artillery cover, Guan Xiangheng, the commander of the 564th Regiment who is in command of the first line of defense, does not take the Japanese army to heart at all, this level of attack, let alone the use of the division's heavy artillery regiment, not even the mortars of the heavy firepower company, only with the light weapons in the hands of the soldiers, Guan Xiangheng is sure that the Japanese army will not be pleased.

Sure enough, when the Japanese attacked a hundred meters away from the first line of defense, they were suppressed by the fire from the position, and the Japanese also wanted to use various stone bunkers on the hillside to attack upwards while returning fire, but the defenders had accurate marksmanship and many automatic weapons. When the Japanese reached 80 meters, it was difficult to move forward. Wing Commander Nishina Shin Osa, who was watching the battle at the foot of the mountain, saw that this attack was difficult to be effective, so he had no choice but to order the attacking infantry brigade to withdraw.

Shiraishi Jiuyasu Dazuo of the mountain artillery wing was also depressed, and he had no choice but to use half of the mountain artillery in the wing first, first launch an artillery bombardment on the defenders' positions, and then build another artillery position with the other half of the mountain artillery, and wait for the defenders' artillery fire to return fire, and then use this half of the mountain artillery to strike at the defenders' artillery positions.

Not long after the eighteen mountain guns of the Japanese mountain artillery wing opened fire, the artillery fire of the defenders' counterattack came again. Before Shiraishi Hiyasu was happy, his face became ugly. It turned out that the trajectory of the defenders' artillery shells showed that the shells were coming from at least 10 kilometers away, and the maximum firing range of his own mountain artillery was only 8 kilometers.

Shiraishi Hiyasu Daisa hurriedly ordered the mountain artillery wing to stop firing and urgently transfer. Half of these eighteen mountain guns have been blown up. Shiraishi Hisakasu Osa hurriedly reported the situation to the commander of Aoki Seiichi's division, and Lieutenant General Aoki Seiichi thought for a long time, ordered to stop the attack, and asked Commander Anami for help.

General Anan was waiting for the battle report of the troops in front in the command headquarters, but just one morning, the 3rd Division first sent a report, saying that it had encountered the ace main force of the China Army on the south bank of the Laodao River, and the division was blocked in the Laodao River, and requested heavy artillery support. As soon as this report was put down, the report of the 40th Division requesting heavy artillery support was sent again.

The Chinese army will defend Changsha City to the death, which is very clear to the generals of Anan Wei, but in just one morning, even the third division with strong combat effectiveness called for help, which Anan Wei and the generals did not expect. Anan Wei and several generals looked at the battle map for a long time before making a decision.

The 14th Independent Field Heavy Artillery Wing, the 1st Independent Heavy Mortar Brigade, and the 13th Wing 1st Brigade all supported the 3rd Division. And the support of the 40th Division was left to the flying troops. These orders were given, and soon the troops that received the orders were mobilized.

The 14th Wing of the Independent Field Heavy Artillery was subordinate to the 3rd Brigade of the Independent Field Heavy Artillery, and this time General Anan left one wing to defend in Yuezhou and brought the remaining two wings to the battlefield. The 14th Heavy Artillery Wing was equipped with twenty-four heavy cannons of the latest 15O caliber type. This heavy artillery has a range of 26,200 meters, a projectile weight of 50.2 kg, great destructive power, and the disadvantage is that it is difficult to move and has a slow rate of fire.

This heavy artillery wing was not expected to arrive until the evening of the 3rd of January, and then the support of the 3rd Division would have to wait until the 4th of January. However, on the afternoon of the 3rd, the 1st Independent Heavy Artillery Brigade and the 1st Tank Brigade arrived at the 3rd Division. The 1st Brigade of Independent Heavy Mortars was armed with twenty-four heavy mortars of 270 mm caliber.

When these two supporting units arrived, Lieutenant General Takahashi Tagaji, the commander of the Third Division, was overjoyed and immediately let the two troops participate in the attack, and although the 24 guns of the heavy mortar brigade had a maximum range of only 2,700 meters, they were only enough to hit the south bank of the Laodao River, and the projectile weighing 133 kilograms was extremely destructive.
