The defenders of Zhenbei City faced a major crisis after the defensive line on the north side was successively broken through by the 6th Division.

In order to save the situation, the defenders of Zhenbei City, while holding the defense line on the north side, transferred the last mobile forces into the central defense line and tried to launch a counteroffensive against the fourth division in front of them.

More precisely, it was a counterattack on the No. 6 heights held by the 15th Regiment under the 4th Division!

The No. 6 Heights are not very superior on the entire front, and their geographical location is far inferior to the three highlands of No. 1, No. 4, and No. 8.

However, since this high ground was conquered by the 15th Regiment under the Fourth Division, the army units of the Lin Dynasty used this inconspicuous high ground to deploy a large number of artillery, and also deployed a large number of heavy artillery on it.

It was precisely because of the direct fire support of these heavy artillery pieces that the 6th Division on the northern flank was able to break through quickly.

The enemy army naturally understands the reason, so it will draw the last mobile force to invest in the counterattack on the No. 6 heights.

In order to recapture the No. 6 Heights, they not only invested more than 6,000 troops and a large number of artillery pieces on the front line of the No. 6 Heights, but also invested more than 10,000 troops in other directions of the central defense line to carry out diversion operations against other units of the Fourth Division to indirectly support the counteroffensive in the No. 6 direction.

Such a large-scale counteroffensive by the enemy army had already attracted the attention of the entire line of troops of the Imperial Army at the very beginning.

"They can't help it!" After Liang Chenglei received the report from the front, he didn't have the slightest worry on his face, but showed a smile: "Let the Fourth Division be steady, don't fight too hard all at once, we will take this opportunity to consume their last strategic reserves!" ”

"The Seventh Army is ready to reinforce the front at any time!"

When he heard that Liang Chenglei asked the Seventh Army to prepare for reinforcements, the generals under him knew without asking that Liang Chenglei was already ready to invest in the strategic reserve of the Seventh Army and lay the battle situation in one fell swoop.

At present, in the Battle of Zhenbeicheng, there are a total of three infantry corps, but only the Third Army and the Fourth Army are actually engaged in battle, and the Seventh Army is acting as a strategic reserve in the rear.

When the Seventh Army, a strategic reserve, was dispatched, either the front line was fought too hard, suffered heavy losses, and urgently needed reinforcements.

Either the enemy's ability to withstand pressure has reached its limit, and for this reason, the Seventh Army needs to be the last straw to crush the enemy.

Now on the all-out front, we have not reached the point of heavy losses.

In this case, the Seventh Army will be dispatched, so Liang Chenglei believes that the enemy army is already reaching the limit, and the purpose of dispatching the Seventh Army is to completely crush the enemy.

As numerous orders were conveyed and issued, numerous troops began to mobilize.

In addition, the defenders of Nanpingzhou in the defense line of Zhenbei City are also very active, so it can be seen that a few days after the battle broke out, the battle between the two sides has reached the most fierce time.

The outcome of both sides may be determined in a short period of time!

Liang Chenglei judged it this way, and some of the senior generals in the front-line troops also knew about it, but the middle- and lower-level officers did not know the macro changes on the entire battlefield, and they could only limit themselves to the current battle situation.

On the No. 6 Heights of A, Dr. Wen Zuoxin looked at the looming enemy troops in front of him, and he was a little worried.

This time the enemy counterattack was very strong, and the determination was also very great!

Before this, the enemy had already launched a large-scale counteroffensive, and their own strong firepower did not have much to surprising to block this large-scale counteroffensive of the enemy, killing and wounding a large number of enemy troops, forcing them to retreat again, at this time there were still a large number of enemy casualties at the foot of the mountain wailing.

However, although the enemy retreated temporarily, it was obvious that they were unwilling to look at them, and they wanted to continue the attack.

If the enemy launches a repeated charge, Wen Zuoxin is a little worried that his ammunition supply will not be available, especially the ammunition for heavy machine guns!

Since yesterday, in the enemy's many counteroffensives, our heavy machine guns have played a major role!

When the enemy finally rushes past the interception of its own artillery and rushes to a distance of a kilometer or even a few hundred meters, it will be intercepted by the fire of its own heavy machine guns and rapid-fire mortars.

In particular, the crossfire formed by the heavy machine guns formed a death blockade at a distance of almost 400 to 500 meters, making it impossible for the enemy to cross at all.

But the powerful firepower of heavy machine guns and rapid-fire mortars is based on their high rate of fire.

The reason why rapid-fire mortars were liked by the generals of the Imperial Army was not because of their range, nor because of their explosive power, but because of their high mobility and rate of fire.

And what the army generals value most is its ultra-high rate of fire.

It's very easy to fire, and if you don't pursue any accuracy, you can shoot more than a dozen shells in a minute.

As long as there are only six rapid-fire mortars, the power of the artillery that erupts in a short period of time is comparable to the rapid fire of an artillery battalion!

And not to mention the heavy machine gun, which survives completely on the rate of fire, and a heavy machine gun that loses its rate of fire has no value.

Powerful firepower is built into the rate of fire, which means a huge amount of ammunition consumption!

Although a lot of ammunition was replenished overnight last night, Wen Zuoxin was still a little worried that the ammunition would not be enough.

Seeing that the enemy was about to launch a second counterattack, Wen Zuoxin did not hesitate any longer, and directly applied to the rear for emergency ammunition replenishment!

Otherwise, the enemy will come a few more times, and the heavy machine-gun bullets of the 15th Regiment and the shells of rapid-fire mortars will be insufficient.

Once the fire interception of heavy machine guns and rapid-fire mortars is lost, the 15th Regiment will not be able to take advantage of the rifle fire alone, after all, the people on the opposite side are all equipped with rear-loading rifles.

Zuo Yikai, the commander of the Fourth Division, has always been concerned about the battle on the No. 6 Heights:

"Today's first counterattack by the enemy on the No. 6 is about 3,000 men, and the second counterattack has increased to 4,000 men, and from the observation of the battlefield, the enemy's two attacks did not invest all the troops, because the width of the frontal defense line of the No. 6 is limited, if they invest too many troops and form a dense charge, they can only become a live target for our artillery fire and heavy machine gun fire!"

"The enemy's counterattack this time is menacing, the pressure on the 15th regiment is not light, give them ammunition as soon as possible, and apply for ammunition replenishment from the military department!"
