Yang Jun's decision was resolute, the measures he took were also decisive, and his actions were swift.

After deciding to retreat, he immediately began to arrange for the troops to prepare for retreat, after all, if you want to retreat, you can't go directly, so you have to have a sequence, and then you have to have some confusing battle plans, for example, Yang Jun decided to retreat, but ordered some troops to launch a counteroffensive.

Otherwise, they don't care about anything, and as soon as the front foot leaves, the shells and bullets will fly from behind.

According to his plan, after these two hours, the troops will be arranged for mobile deployment, and at the same time they will resist and even launch a counteroffensive, and after two hours, it will be a little dark, and they will enter a full retreat.

Although the situation will be chaotic when retreating at night, and it is possible that many troops will not be able to withdraw, it is better than waiting until tomorrow when the whole army is wiped out.

However, he still overestimated the defensive ability of the troops under his command, and even underestimated the roundabout offensive ability of the Southern Navy!

In the evening, when he sensed that the enemy's defensive line was inappropriate and that it was possible to retreat overnight, Lin Ziran decisively ordered a full-scale counteroffensive, the First Army was put into a full-scale offensive, and the Ninth Division of the reserve was also put into battle.

At the same time, the pace of the Second Army's detour began to accelerate, and even after dark, the troops continued to advance.

When Lin Ziran ordered the troops to launch a full-scale attack, the offensive capability of the Southern Navy also exploded.

Previously, the two divisions under the First Army said that they were attacking, but they were more still artillery bombardment, and small-scale infantry infiltration attacks, but they did not say that they directly launched a full-scale attack.

But now, the First Army launched a direct all-out attack, and a large number of infantry units launched a large-scale attack under the cover of artillery.

Even the 9th Division of the Reserve was gradually put into operation.

In the face of the strong attack of the Southern Navy, the frontal defense of the Quyang Prefecture Army was in the same situation as the defenders of the previous western defense line.

What's going on?

I can't hold it!

In just one hour, when the sky was about to get dark, there were already large sections of loopholes in the frontal defense line of the Quyang Prefecture Army, and the First Army had successively tore open two huge gaps, and the Ninth Division, as a reserve, was advancing rapidly, and then staged what the Southern Navy was best at: breakthrough, detour, outflanking!

Relying on powerful firepower, there is no doubt about the frontal offensive capability of the South China Navy, and the reason why the First Army fought slowly before was purely to drag out time and let the Second Army make a roundabout.

Now when he sees that the enemy is about to run, he will naturally not procrastinate, and immediately burst out with strong combat effectiveness.

And if we really want to talk about combat effectiveness, the combat effectiveness of the first division under the First Army is well-deserved first in the whole army.

The First Division, the First Infantry Brigade, the Second Infantry Brigade, the First Artillery Regiment, the First Baggage Regiment, the First Cavalry Regiment, etc., all belong to the earliest units of the Southern Navy.

Unlike other units that were formed for a few months or more than a year, the formation time of the various units of the First Division can basically be traced back to the 48th year of Yongchang, while the time of large-scale formation of the army was 49 years, and the subsequent 52 years after a series of wars.

In addition to the long time it has been formed, there are several other factors that are very important, one is tactics.

The two infantry brigades of the 1st Division were the first units in the South China Navy to come into contact with the new type of light infantry tactics.

The second is the quality of officers and backbone non-commissioned officers, and the graduates of the Luo'an Military Academy in the previous many periods, the top graduates were basically assigned to serve in this hardcore lineage unit, which basically laid the basic tactical quality of the officers under the first division.

After Lin Ziran asked the military academy to start the ideological course, a group of young and enthusiastic officers who were full of the reunification of Nanhai Prefecture and the reunification of Daheng were also selected to serve in the first division, which led to the fact that when there was a war, the first division was often the most unfatal.

As for the equipment, let alone that, basically whatever advanced equipment the South Navy has, it will give priority to equipping the first division.

The first Luo'an III rifle newly produced by the Fuyuan Ordnance Factory to be reequipped was the First Division.

The 75-millimeter field gun with better performance produced by the Nanzhou Machinery Bureau was also the first artillery regiment under the first division to be reequipped, but it was the first fully equipped breech-loading rifled artillery regiment in the South China Navy.

various later newly developed seventy-five-mm howitzers; The 60-mm and 80-mm rapid-fire mortars were also given priority to equip the 1st Division.

It is said that at that time, the artillery regiment of the first division was still equipped with 150 mm howitzers, but later the unit was restructured and the 150 mm howitzers in the divisional artillery regiment were cancelled, and the installation was withdrawn.

In terms of combat experience, officer quality, mental outlook, and equipment level, the First Division is the highest among all units in the South China Navy.

And the First Division has never disappointed Lin Ziran, regardless of whether it is going north or south or eastward, the First Division has always been the core main force that Lin Ziran relies on the most, and it is responsible for the main attack in every battle.

This time, the First Division also did not disappoint Lin Ziran.

After the launch of the all-out counteroffensive, the 1st Division tore through the enemy's first defensive line node in half an hour, and then spent half an hour expanding this breakthrough point and rapidly advancing into depth.

When the 1st Division and the 9th Division, which was the reserve, quickly advanced deep into the enemy's depth through this breakthrough, and then presented a roundabout outflanking posture, it was basically possible to declare the complete end of the enemy's frontal defensive line.

At this time, it is not dark yet!

Yang Jundu was still preparing for a retreat, and before he could make a full retreat, he had already watched his troops completely collapse.

Not because of the collapse after the western flank was breached, but because of the total collapse of the frontal line of defense after it was forcibly broken through!

The western defense line was bypassed and broken by the enemy, and he could still accept it, after all, the western defense line was the weakness of the entire defense line, and the troops deployed at the beginning were not very large.

But the frontal line of defense was easily broken through by the South Navy like a paper paste, and he could not accept it.

But what is unacceptable must also be accepted.

The defense line had already collapsed in advance, and there was no way to wait for dark to carry out a full-scale retreat, so Yang Jun had no choice but to order the troops to retreat in advance.

This retreat basically heralded the complete collapse of the entire front, not just the western or frontal lines, but all the lines.

It's all gone, can you not collapse.

Looking at the enemy troops all over the mountains, Lin Ziran did not continue to observe and direct the battle with binoculars on the mountain.

So far, the overall situation has been decided, and the next thing is the closing stage, which is nothing more than how many results can be gained.

Now, Lin Ziran is already planning to set his sights on the other three directions, especially the Western Front, where the Sixth Division has reported the menacing enemy army more than once!
