Behind the mine-sweeping tanks was the main attacking force of the British army, and dozens of tanks of various models covered a regiment of infantry to launch a charge towards Heights Zero.

This was a tentative offensive by the British, hoping to find out the weaknesses of the German firepower and defenses, or to further clear the obstacles in front of the line of defense so that the follow-up troops could advance more quickly.

The shells were still roaring on the high ground, not weakening but intensifying, and many of them hit the anticline...... It is clear that the mortar units of the British army also joined the bombardment.

Soon, the bombers flew over the high ground in droves and dropped bombs, and in an instant the whole battlefield was plunged into a screech of bombs and explosions, and the soldiers hiding in the tunnels were like small insects in bottles, rolling and shaking in the stormy waves.

In the dark, Qin Chuan felt that someone had vomited, because the vomit had splashed on him, and at the same time there was a sour smell in the air, but he couldn't find out who did the "good thing", and it didn't make much sense to speak or give orders at this time, because the explosion of the shells and bombs had drowned out most of the sound, and Qin Chuan could only wait in the tunnel, waiting......

With a "boom", a cannonball exploded at the mouth of the tunnel, and the smoke with the smell of gunpowder obscured the only bit of light and rushed into the tunnel like the devil's black hand, and a coughing sound was immediately heard in the tunnel.

The bombardment lasted for more than twenty minutes, and a sharp whistle finally came from outside the tunnel, and Qin Chuan immediately waved his hand and led the soldiers out of the tunnel.

This is a tactic of tunnel warfare.

Generally speaking, the soldiers stayed in the trenches and hidden, just like Qin Chuan had done when he was defending along the Alexandria Line.

The disadvantage of this is that it is not effective against artillery, because at most it is a camouflage net placed on the trench so that the enemy artillery cannot determine the location of the trench...... But this is obviously unreliable, because the enemy only needs to launch a charge to easily detect this.

Enemy shells would then come at the trenches in pieces, many of which could even be fired directly into the trenches, such as mortars with curved ballistics.

As a result, the offensive and defensive sides often need to meet each other at this time.

For example, the use of artillery to suppress the opponent's artillery, and the artillery battle will soon extend to the struggle for air supremacy...... This is a regular offensive and defensive battle.

Before the U.S. military entered the war, the German army could afford to fight regular offensive and defensive battles, and even won victory after victory because of Rommel's proper use of tactics, that is, attacking with inferior forces.

However, after the U.S. military entered the war, because the air power was fully tilted towards the Allied forces, the regular offensive and defensive warfare was tantamount to suicide for the German army...... Allied planes would blow up any German artillery unit that dared to return fire, and German fighters did not dare to attack easily due to their numerical inferiority.

So the irregular defensive warfare of tunnel warfare has a place to play.

The German soldiers were not defending in the trenches, but hiding in the trench fortifications. In this way, they were able to preserve their viable forces despite the enemy's full air and artillery superiority.

But then a problem arises.

The soldiers hiding in the tunnels did not know when the enemy rushed to the high ground or where they were rushing, and it was even possible that the soldiers hiding in the tunnels would occupy the high ground with a single charge.

The solution to this problem is to create a reconnaissance group.

This reconnaissance group generally does not directly participate in the fighting, and its task is reconnaissance and vigilance...... Their tunnels were built near the hilltop position, or near the ridgeline. (The so-called ridge line refers to a line around the top of the mountain where you can see the positive slope with your head sticking out.) ）

When the enemy is bombing, the reconnaissance group is responsible for observing and guarding the hilltop position and the area around the ridgeline...... Even if there is a danger of being blown up, it must be outside, and if you are killed, you have to make up for a few, so that you can always keep an eye on the enemy.

Then, when the enemy advances to the danger line or the bombing develops to a quasi-safe stage, the reconnaissance group sends a signal for the main forces in the tunnel to come out of the tunnel to defend

This is the quasi-safety stage...... The enemy bombers had already dropped their bombs and left, and tank guns and cannons could only hit the positive slope, and only a small number of mortar and howitzer shells could still hit the anti-slope plane, which could no longer cause mass damage to the German troops.

Qin Chuan led his soldiers to climb up to the top of the hill along the communication trench that had almost been blown into a small ditch, and looked down, where groups of British soldiers were approaching the high ground in a straggler formation.

"They're supposed to be Otalians!" Bazel said to Qin Chuan, who had caught up.

Qin Chuan understood what Bazel meant, the British did not have the courage to directly attack the high ground under such circumstances.

"It's your time to behave!" Bazel patted Qin Chuan's shoulder.

As soon as Qin Chong waved his hand, the soldiers of the French battalion entered the position with rifles.

It was a strange way of fighting, with French soldiers fighting in harmony with German soldiers...... France is the French battalion, and Germany is Qin Chuan's second company.

The soldiers of the French battalion were in the first line, and the second company was a backup unit under the leadership of Bazel.

This was Qin Chuan's suggestion, and the reason was that he intended to let the French battalion perform a special task in the near future.

Needless to say, what this task was, soldiers disguised as Free France, more precisely "Fighting France", infiltrated the Gafsa battle. (Note: De Gaulle's government was originally "Free France", later changed to "Fighting France")

This is undoubtedly a dangerous task, if the French battalion has not been tempered or even killed...... I'm afraid that it will leak out in two clicks.

Now, it was an opportunity for the French battalion to temper.

The sound of the artillery gradually weakened, because the British soldiers had approached the hilltop position, and if they fired any more, the shrapnel from the shells would inevitably hurt their own people.

So in the smoke of gunpowder, the British troops, who were divided into several groups and advanced by covering each other by the terrain and craters, loomed in front of the eyes of the French battalion.

In the rear of these British troops, a platoon of tanks was waiting at the foot of the hill, with anti-aircraft machine guns and mortars aimed at the front of the British advance and adjusting to provide cover for them at all times.

"Steady!" Qin Chuan said: "Just like you did in training, aim at the target and pull the trigger, and then you can win this battle!" ”

The more difficult and dangerous it is, the more Qin Chuan will simplify it, because Qin Chuan knows that only in this way can these recruits be more relaxed.

As for whether they can pass this hurdle, it's up to them.
