The unprepared British army did not expect this situation at all, and the first attack was beaten in a daze.

Colonel Bud had a feeling of infirmity, and he punched out hard but hit the mud, and he didn't say anything and didn't hit him.

"General!" In subsequent contact with Montgomery, Colonel Bard reported: "I don't think their tunnels are independent, they work together as a whole!" ”

"What do you mean?" Montgomery asked.

"I don't know!" Colonel Bard replied, "But I have reason to believe that they have communications equipment in the tunnel. If one of the heights was attacked, the other heights would cover it, and we suffered dozens of casualties in the attack, but we didn't even touch their shadows! ”

"But how can they communicate in the tunnel?"

"I don't know, General!"

After thinking about it, Montgomery ordered: "Try to cut off their lines of communication, and ...... Try to attack several heights at once, so that they can't cover each other, understand? ”

"Yes, General!"

And then Colonel Bud did just that, dividing his troops into three parts...... In fact, in order to ensure his superiority in firepower, Colonel Bard did not divide his troops into three parts, but transferred two more battalions from the 15th Panzer Division, which were used to attack the 217th and 193rd heights behind the 312 flank.

It should be said that this style of play is correct, even if the British army's attack on Heights 217 and 193 is only a feint, it will also suppress the firepower of these two heights, so the fire cover on Heights 312 will also be reduced in progression.

Indeed, this time the British army successfully attacked the 312 heights, although they still had to face the problem of covering each other at the mouth of the tunnel and firing black guns, but at least they did not need to worry about the firepower from other directions.

However, even so, they found themselves at a loss.

"What are we supposed to do?" Major Eugène, who commanded the 2nd Infantry Battalion, asked Colonel Bard over the walkie-talkie, "We've found their holes, these are holes about six inches in diameter, blow them up?" ”

This quickly stopped Colonel Budd.

Blowing up the hole obviously won't solve the problem, as they've done it before.

"Try to get in!" Colonel Bard said.

"But the Colonel!" Major Eren asked puzzledly, "How can I attack it?" ”

"No matter what method is used!" Colonel Bard replied impatiently, "Grenades or whatever, just blow them up for me!" ”

"Yes, Colonel!"

Major Eugène hung up the phone and began to feel embarrassed, but he still called a few of his capable men and said, "Listen, we have to try to find it, I know it's dangerous, but it's war, isn't it?" I want you to prepare the grenade, like street fighting training, throw it in and wait for the grenade to explode, then rush in, see whatever it is, shoot it, understand? ”

"Understood, Major!"

"Understood!"

……

In a few minutes, the brave soldiers were ready, and they were armed with Thomson submachine guns...... This submachine gun has a large ammunition capacity and a much shorter barrel than a rifle, which is obviously more suitable for close combat in tight spaces in tunnels.

In addition, each of them had ten oval grenades on their bodies and in their backpacks...... They were ready to open the way with grenades and then strafe them with submachine guns.

As for the other things, such as water bottles and the like, they were all left outside, and they needed to travel as light as possible to move as quickly and flexibly as possible in the tunnel.

This offensive tactic does work, as the grenade kicks up a cloud of smoke when it explodes in the tunnel, and the sniper in the sniper room who is responsible for blocking the entrance to the tunnel through a steel pipe will be obscured.

But for this, Qin Chuan had been prepared when designing the tunnel, and after hearing the sound of a grenade exploding, the sniper waited for a while before pulling a grenade and stuffing it into the steel pipe above...... It was an inclined steel pipe buried in the earth, and the grenade glided all the way through it before it slid to the front of the mouth of the tunnel.

At this time, the prepared British soldiers rushed into the tunnel...... Before they could take a few steps, they felt something fall nearby, and it was still "snorting" and smoking.

"Grenades!" The British soldiers only had time to shout, and the grenade exploded with a "boom", and the British soldier who was walking in the forefront was killed on the spot, the second was wounded by shrapnel and let out a wail, and the third soldier hurriedly dragged it out, but when it was dragged to the mouth of the tunnel, a bullet flew out of it and killed it, leaving only the wounded second one to be dragged back by his comrades in time.

"God!" "We don't know the inner workings of the tunnels," said Major Eugène, "and they could easily have killed us, while we were beaten like blind men!" ”

The attacks on several other tunnels were similar, with some British attempting to throw smoke grenades and rush in. But the Germans still solved the problem by just throwing a few grenades. Occasionally, a few British soldiers slipped through the net, but were quickly beaten into a sieve by the German soldiers guarding inside.

"It's Tulao, Colonel!" Major Eugène reported to Colonel Bard: "This is a sheer waste of soldiers' lives, and we cannot succeed!" ”

Colonel Bard replied helplessly: "Blow up the mouth of the pit and mark it, we will think of a way!" ”

In fact, this is not the only thing that bothers Colonel Bard.

The high ground on the Gabez line was one after the other, and the 312 high ground was covered by two high ground on the flank, and the two high ground behind the flank was covered by two other adjacent high grounds......

As a result, the two units used to feint on heights 217 and 193 were bombed and strafed by covering units from other directions.

There were only two battalions in those two directions, which were quickly defeated, and then Heights 217 and 193 covered Heights 312.

Soon, the situation of the first attack reappeared, and the British left dozens of corpses and were beaten down again.

"This tactic won't work, General!" Colonel Bard reported to Montgomery: "In order to take one high ground we must suppress the fire of two high grounds, and in order to suppress the fire of two high ground we must suppress the fire of the other four...... Unless we can attack all the high ground along the entire line at the same time, it won't have much effect! ”

It was only then that Montgomery discovered the problem, and it turned out that the Germans had trapped something else but the tunnel fortifications they had built.
