Zuo Yikai, the commander of the Fourth Division, was in a trench on the front line at this time, using a telescope to observe the surrounding battlefield.

At this time, the Fourth Division under his command had become the most fierce place on the entire battlefield.

The enemy seems to have concentrated most of their artillery in this direction, and based on the continuous falling shells, the enemy has concentrated at least a hundred guns.

This is estimated to be more than 90 percent of the enemy's artillery.

There were also quite a few troops, and it was estimated that the 4th Division was facing at least 25,000 enemy troops head-on.

The enemy launched a counteroffensive against the 4th Division with twice the strength of the force, which made the 4th Division a little difficult.

However, Zuo Yikai still did not apply for reinforcements of troops, but only applied for ammunition supply.

Although the enemy has a lot of troops, it is not so easy to break through the defense line of the 4th Division, and although the enemy has nearly 100 artillery pieces to provide support, the 4th Division can get more artillery support at this moment.

In addition to the 4th Division's own more than 50 divisional artillery pieces and dozens of rapid-fire mortar guns, there are also 2 to 300 artillery pieces in the rear that can provide fire support for the Fourth Division.

The fact that the 4th Division, as well as the enemy forces on the opposite side, were able to receive such dense fire support was also related to the characteristics of the Battle of Zhenbei City itself.

The battlefield of the Battle of Zhenbei City was actually very small, and the defenders built an irregular square defense line around Zhenbei City around the mountains and hills on the periphery of Zhenbei City, with an area of only about 50 square kilometers.

At the same time, when the defenders of Zhenbei City deployed the defensive line, it did not mean that all the troops were deployed along a defensive line, but relied on the special terrain such as the surrounding mountains to build a complete field defensive line.

With a number of high ground as the core, such as Heights A 1 and then Heights A 9, these nine heights of various sizes formed the core of the entire defensive line, and the enemy deployed heavy troops and main artillery on these heights.

So this battle is said to be a siege battle, but it is actually a battle to attack one hill after another.

When the forces of both sides are concentrated in such a small area and concentrated around the mountain, then the forces of both sides will show a very close posture.

The defenders had more than 100,000 troops, and the attackers had nearly 200,000 troops.

The two sides combined with more than 300,000 troops, concentrated in such a small area, resulting in dense personnel and extremely dense firepower.

Moreover, because the battlefield is small, as long as the artillery is properly deployed, it can be done without artillery maneuvering, and can be supported and covered by simply turning the muzzle.

Therefore, the enemy was supported by nearly 100 artillery pieces, and the 4th Division was also able to receive fire support from 2 or 300 artillery pieces when the battle situation was urgent.

The artillery of both sides continued to bombard each other's positions, especially the core of the war.

Most of the enemy's artillery was shelling the No. 6 Heights, which put the 15th Regiment stationed on the No. 6 Heights under great artillery pressure.

Most of the time, the soldiers could only hide in the anti-artillery holes in the trenches, leaving only a few to observe in the sheltered observation holes, and the shells continued to fall and explode, which inevitably brought some casualties.

This caused some trouble for the 15th Regiment, but it was only a minor problem.

They were much luckier than the enemy counter-attacking soldiers at the foot of the mountain, at least they still had deep trenches and anti-artillery holes!

On the opposite side, the enemy army only has some temporary trenches at most, and more of them lie in the craters to avoid shelling!

However, these temporary trenches and craters can certainly protect against a certain amount of howitzer shelling, but the effect is not very good after all, and large-caliber shells can still cause them a lot of damage.

In addition, air-burst shrapnel is a nightmare for them!

After this thing explodes directly in the air, the steel ball will follow the flight path of the cannonball, directly hitting a large area of ground below, just like rain, making people unable to hide.

Even if they bear the shelling, they still need to launch a charge counterattack!

As their officers brandished their sabers and whistled, the soldiers climbed out of their trenches and craters and continued to charge forward, often under heavy rapid-fire mortar fire.

These shells continue to fall, causing them a lot of casualties, and if they continue to go on, they will be strafed by heavy machine gun crossfire!

After the soldiers fell one by one, no matter how loudly the officers shouted, it was already impossible to let their troops advance even a single step!

When the enemy launched three counterattacks in a row to no avail, Wen Zuoxin at the top of the mountain knew that it was impossible for them to launch a counterattack again!

Being able to forcibly launch three consecutive charges under such heavy casualties under the powerful firepower of his own side has already exceeded Wen Zuoxin's prediction.

Wen Zuoxin would not believe that the enemy army could organize another attack with such heavy casualties!

If the Pingnan Prefecture Army on the opposite side was so strong, they would have unified the world a long time ago.

Just as Wen Zuoxin expected, Xia Sheng Shaoqing, the commander of the Ninth Division of the Pingnan Prefecture Army on the opposite side, looked at his own wounded and corpses almost all over the mountains in front of him.

He took a deep breath and closed his eyes!

Although he still had a brigade of strategic reserves under his command that had not been used, he knew that this counterattack was a complete failure, and even if he filled in the last brigade, it would not change anything.

The firepower of the southern army on the opposite side is too strong, especially the firepower network formed by the opponent's rapid-fire machine guns and rapid-fire mortar guns, which is simply not something that the soldiers can break through with courage.

There is no hope of recapturing No. 6, how should I ask Yue Bu, the commander of the urban defense of Zhenbei City, to ask Shangqing for an explanation?

What's more, their own side has not been able to recapture the No. 6 Heights of Jia, and they have suffered heavy losses, can they still hold the north city of this town in the future?

Xia Sheng didn't give an answer to this question in his heart!

But he has such doubts, then it is enough to prove the danger of the situation.

If he had enough confidence, then there would be no doubt about whether he would be able to hold the northern part of the city.

Once there is doubt, it means that he has lost confidence.

Because of the loss of the No. 6 Heights of the A6 Heights, which led to the overall loss of the defense line in the central and northern parts of Zhenbei City, the enemy's Sixth Division once killed only a kilometer away from the urban area of Zhenbei City.

The troops drawn are his Xia Sheng's Ninth Division!

The last strategic reserve in the defenders of Zhenbei City.
