Colonel Bard reported to Montgomery on the offensive and the various failed attempts.

Although the report was detailed, Montgomery was still confused and did not understand what was going on.

"Flamethrowers can't do damage to enemies either? Are you sure you've been burning long enough? ”

"You're already standing in front of the mouth of the tunnel, and you're still helpless?"

……

Colonel Bud was a little speechless at Montgomery's words, but he didn't know how to argue with them.

This is also one of the shortcomings of Montgomery's lack of presence on the battlefield, if he had been on the front line and watched first-hand how the British army fought and was defeated, then he would not have said these ignorant words.

But because Montgomery didn't see it, he suspected that the British army was not doing their best, and Colonel Budd, who was fighting desperately on the front line, would have nowhere to say anything.

It is no wonder that Montgomery did not believe it, he could not have imagined that the British army had already attacked the high ground, and there was such an obvious superiority in strength and equipment, but it was defeated again and again.

What Montgomery didn't know was that tunnel warfare was precisely a tactic against the enemy with superiority in troops and equipment...... As soon as the troops hid in the tunnels, almost all modern equipment such as airplanes, artillery, and tanks were no longer functional.

Even if the planes and artillery bombarded a single blow up some of the tunnels, the point was that the British army outside could not see the results of the battle at all, so they thought that they were blindly bombing, doing useless work and wasting ammunition from beginning to end, which was a very powerless feeling.

In fact, not to mention that the British are helpless against this tactic now, = even in modern times, when the United States dealt with Vietnam, they were helpless in the face of this tactic. (Note: During the U.S.-Vietnam War, Vietnam learned a lot from China's tunnel tactics during the War to Resist U.S. Aggression and Aid Korea)

The only thing that really defeated this tactic was the China that invented it...... In the subsequent self-defense counterattack against Vietnam, Vietnam tried to drag the Chinese army into the quagmire with this tactic in the same way, but China is the ancestor of this tactic, and of course it will not be stumped by its apprentices.

The method of dealing with it is a bit stupid, which is also the so-called "pulling the net to clear it": no matter how much 3721 first sets a fire to it for a few days and nights, burns all the plants and trees into a piece of charcoal, and then pulls a "net" on the map, that is, each high ground is divided into a small grid, and each grid sends a force to be responsible for carefully clearing it...... Caves, tunnels, and invisible tunnel entrances are all found, either blown up, burned, or buried (the tunnel mouth is sealed with reinforced concrete), and then blocked with firepower, so that all the enemies hiding in the tunnel are blocked so that none of them can come forward.

Once one or two of the heights have been cleared, they will not be able to provide fire cover for the others, so a breakthrough will be found to deal with the other heights in the same way.

With the strength of the British army at this time, it is completely possible to carry out the "dragnet clearance", but the British and US forces basically would not have thought of this method.

On the one hand, this is due to the character of Europeans and Americans, who tend to use more modern and "high-minded" methods, which may have something to do with their industrialization process, or the way of thinking of a commercial country...... They don't think too much about simple methods that require a lot of labor to clean up one by one.

On the other hand, it should be said that European and American armies have always been accustomed to regular warfare rather than being good at guerrilla warfare...... The essence of tunnel warfare is a kind of guerrilla warfare, which is nothing more than the use of tunnels to realize the strategic principles of "the enemy advances and we retreat, and the enemy retreats and we advance," "the enemy is stationed and we disturb, and the enemy is tired and we fight."

So what "El Alamein Line", "Matare Line"...... The British and American troops were not afraid of these regular defensive lines that could be seen on the ground, and at most they piled up ammunition.

But in the face of this kind of tunnel defense line where they don't know where to pile up with ammunition, they have no choice.

The most important thing is that Qin Chuan will not tell the British how to deal with tunnel warfare, so let them be poor outside.

After thinking about it for a while, Montgomery said to Colonel Bard, "Colonel, we seem to have deviated from the point of this battle!" ”

"What?" Colonel Bard asked, "I don't understand what you're saying, General!" ”

"What is the purpose of our attack on these heights?" Montgomery asked rhetorically.

"Open the supply lines!" Colonel Bard replied: "Or maybe you can say open a way out!" ”

"Yes!" Montgomery said, "So if you can all take the enemy's high ground and even stand in front of their tunnel mouth and breathe fire into it with flamethrowers, why can't we get our supplies in?" Why can't our troops be withdrawn? ”

Colonel Bard let out an "oh" and replied, "I know what to do, General!" ”

Colonel Bud did know what to do, and that was to ignore the rest of the world and focus on keeping the roads safe and the traffic flowing.

It should be said that there is nothing wrong with the idea itself, as long as the road is clear, all the problems of the British army will be solved, as for how many Germans are hiding in the tunnels...... Just let them keep hiding!

Colonel Bard then focused on dealing with the pit openings that were facing the road...... In fact, he didn't have any way to deal with it, which was to blow up the mouth of the tunnel, and then pile stones and even bury mines at the mouth of the tunnel. When you're done, put a few more sentries or a machine gun on the outside in case someone comes out.

Colonel Bard then asked the soldiers to construct a defensive line on the hilltop position on the basis of a positive slope...... There are fewer tunnels on the positive slope, where a regiment of the Australian 6th Infantry Division is stationed.

Colonel Bard hoped to use this line of defense to condescendingly block the mouth of the anticline with fire.

His order to the soldiers was: "Kill everything that comes out of the ground, not even a mouse!" ”

However, this is just a good wish, not to mention that the tunnel entrances are set up in relatively secret locations, not to mention that a large number of plants on the high ground can be used as cover, and even some invisible tunnel entrances are next to the British troops They have not been able to detect it.

The usefulness of this is another matter......

After doing this, the highway that Montgomery and Colonel Bud had hoped for was not clear.

Just as a convoy of cars was passing the road at the foot of Hill Zero just before nightfall, a field of shells slammed into the cars from different directions with a whistling sound...... A dozen cars were in a mess in an instant, and soon they were either blown into flames or overturned to the side of the road.

"We were wrong again!" Colonel Bard said: "If you want to keep the road open, at least block all enemy heights within a radius of a few kilometers around!" ”
