Xia Sheng's 9th Division was a strategic reserve in the defenders of Zhenbei City, with three infantry brigades and an artillery regiment, which consisted of two 100-mm front-loading rifled gun battalions and a 75-mm breech-loading rifled gun battalion, plus other divisional troops, with a total strength of more than 15,000 people.

It's just that the artillery regiment and the baggage regiment and other units have been uniformly recruited and transferred by the city defense headquarters to participate in the war.

The Ninth Division in Xia Sheng's hands served as a strategic reserve, and in fact there were only three infantry brigades.

Everyone knows the importance of the No. 6 Heights, and Xia Sheng also knows it.

So at the beginning of the battle, Xia Sheng mobilized two brigades under his command to participate in the attack!

Two infantry brigades, supported by hundreds of artillery pieces in the rear, charged three times in total!

And specially chose a different direction to attack!

But it still did not work, and the attacking troops retreated without even rushing to a distance of 100 meters from the enemy line.

If you can't rush up, forget it, and it will cause heavy casualties!

Two brigades with a total of 7,000 troops have been invested, and now less than 5,000 people have been able to retreat to the starting position, and more than 2,000 people have died on the way to charge and retreat!

The casualty rate reached 30 percent!

This casualty ratio made Xia Sheng, who had been on the battlefield for a long time, know very well that his two brigades had been completely abolished, and if he wanted these two brigades to restore their morale and launch an offensive again, they had to at least rest for a long time and replenish new recruits.

If you force them to counterattack again now, I'm afraid someone will have to shoot themselves with a black gun!

In fact, if before the attack, if the attacking troops had known that there would be such a large casualty rate, they would rather rebel than attack!

Seven thousand people rushed three times, and the time before and after was less than two hours.

However, in less than two hours, the casualty rate reached 30 percent, and more than 2,000 people were killed or wounded.

This result was not something that Xia Sheng could have predicted, nor was it something that the attacking troops themselves could have predicted!

In fact, as soon as they rushed forward and could not move, the attacking troops had already stopped attacking, and the reason why there were so many casualties was purely unexpected.

Wen Zuoxin of the 15th Regiment felt that he was running low on ammunition, and in order to strengthen the utilization rate of ammunition, he ordered his troops to put the enemy closer to fight, so that they could make better use of the crossfire of heavy machine guns to kill and injure.

That is why the enemy was able to rush to within 300 meters, or even to a distance of about 100 meters, because at the beginning, the heavy machine guns of the 15th Regiment did not make a full interception, but let them go.

When they entered the crossfire line, it was a sudden burst of intensive fire!

After this firing, a large number of the enemy's forward troops were killed and wounded, and even those who were not killed were suppressed on the ground and could not move, and the subsequent suppressed and immobile people were also continuously killed.

Almost most of the enemy's attacking troops did not return, and most of the troops that withdrew were those who were behind.

This situation was all seen by Xia Sheng, and this also made him lose the confidence to counterattack the No. 6 Heights!

When Xia Sheng's Pingnanzhou Ninth Division failed to counterattack the No. 6 Heights of Jia, it also meant that there was an important strategic turning point in the entire Zhenbeicheng Campaign.

It means that the enemy has completely lost the ability to counterattack strategically, and can only rely on the inherent fortifications to resist stubbornly.

However, the existence of the No. 6 Heights allowed the artillery units of the Imperial Army to carry out accurate shelling of most of the battlefield without any hindrance.

This point was very fatal, and the rapid breakthrough of the 6th Division was due to the favorable artillery support from the heights of Jia6.

In the future, as long as the No. 6 Heights are maintained, then the Imperial Army will be able to deploy heavy artillery positions on it all the time, and even deploy more artillery, so as to provide more powerful support to the entire battlefield.

At that time, it will be more difficult for the defenders of Pingnan Prefecture to hold the defense line of Zhenbei City!

In this case, the defenders of Pingnan Prefecture in Zhenbei City seem to still have a large number of troops, and they continue to hold most of the defensive line, and even today they can organize more than 20,000 troops to launch a local counterattack.

But from today onwards, this situation will be completely changed!

The next day, the enemy did not continue the counteroffensive, while the 6th and 11th Divisions continued to attack in the north-central region!

The scope of its offensive is not too large, after all, this kind of offensive operation is a repeated battle for each hill, and it is impossible to rush forward.

If you foolishly go around the hill and go straight forward, you will be killed and wounded by enemy crossfire in the open area.

However, this steady push may seem slow, but it is extremely effective.

Especially with the continuous advancement of the Sixth Division in the north, its troops are already about to enter the urban area of Zhenbei.

The divisional artillery fire carried by the unit itself has already begun to shell some key buildings in the city and enemy fire nodes.

Although the battle in Zhenbei City has been going on so far, it seems that the enemy army still has a large number of troops and still has a large number of positions, but anyone with a discerning eye can see that the defeat of the defenders of Zhenbei City is already a matter of time!

On August 10, seeing that the front-line operations were going well, especially in the loss of the Fourth Army's advance, Liang Chenglei finally decided to invest in the Seventh Army of the Strategic Reserve.

On the same day, the 19th Division of the 7th Army was put into operation, and the reinforcement of the unit was in the direction of the 6th Division.

Reinforced by the 19th Division, the 6th Division, was able to draw forces to maintain the defensive line on both flanks and concentrate on a frontal breakthrough, so the pace of advance was further accelerated.

The next day, with the 19th Division defending the rear flank, the 6th Division concentrated its forces to launch a massive attack on the front and made a breakthrough.

In the afternoon of the same day, the forward troops of the 6th Division broke through about 2,000 meters in one breath and reached the bank of the Jing River.

Thus splitting the enemy army into two parts!

About 20,000 enemy troops in the north were compressed into a narrow strip of only seven or eight square kilometers.

Immediately after that, the 6th Division, together with the 11th Division, and the 19th Division, launched a full-scale siege of 20,000 enemy troops in the narrow northern strip at about five o'clock in the afternoon!

After three hours of fierce fighting, when the sky was completely dark, the enemy forces in the area had completely lost their organization.

Although night fell, the fighting did not stop, and in order to prevent the enemy from re-establishing contact during the night, the 6th and 11th Divisions continued to launch limited attacks.

Although the attack was not as large as during the day, it still severely damaged the enemy and thwarted the enemy's attempts to re-establish contact and stabilize the battle line.

At dawn the next day, the 19th Division launched a fierce attack as the main attacking unit, and four hours later, near noon, the remaining enemy forces in the encirclement completely lost resistance, and a large number of enemy troops began to surrender or be surrounded and captured.

This declared the annihilation of the 25,000 defenders in the northern defense area of the Zhenbei City Defense Line.
