Of course, this is not how powerful Qin Chuan is, but it has also been ...... in history Of course, this is the history that Qin Chuan knows.

This kind of tunnel is used by no one else, it is the same way that China and Vietnam used to construct tunnels during the stalemate on the border.

The geology of the Sino-Vietnamese border is also humid and rainy, and Vietnam is still in the half-year dry season and the half-year rainy season, when the rainy season is almost half of the tunnels are water, and the soldiers of the Chinese army who hold on to the tunnels are often soaked in water or even in their own filth......

The war on the Sino-Vietnamese border is more special, and the Vietnamese devils are not as squeamish as Britain, the United States and other countries, and they will also build tunnels, that is, the mode of tunnel warfare against tunnel warfare.

Sometimes the tunnel between friend and foe is only a few meters away, and you can hear each other's farts, so all the and urine are sprinkled in the tunnel.

This is not bad in the dry season, but the tunnel stinks, but when the rain pours into the tunnel in the rainy season, all the dried filth floats on the water and dangles in front of the soldiers...... That's not something to look good at.

Of course, there are still some differences between the tunnels built by Qinchuan at this time and the tunnels at that time, when the Chinese soldiers had already used corrugated steel plates in large quantities...... Corrugated steel plates are undulating steel plates in a wavy shape, just like arch bridges, which can effectively disperse the impact of the cannonball into the surrounding soil layer.

Therefore, the Chinese soldiers cover a layer of soil with a layer of logs horizontally, pave a corrugated steel plate with a layer of soil, and then layer a layer of logs and a layer of soil longitudinally...... In short, it is to spread until you feel safe in your heart.

But the sense of security is not enough no matter how much it is stored, let alone on the battlefield.

This kind of tunnel has a drawback: because it is horizontal, the whole tunnel is actually not far outside the mountain, so if the surface position is completely occupied by the enemy, the tunnel can easily be dug by the enemy and stuffed with grenades, explosive packs, etc.

However, considering that this battle is not a stalemate with the enemy like the Gabes Line, it is more important to avoid artillery and the bombing of enemy fighters, and the ground is to block the enemy's charge, so it also happens to be applicable.

While Qin Chuan and others were actively preparing for war in Sicily, Montgomery, Eisenhower and others were also discussing offensive plans.

The Supreme Commander of the Allied Forces was undoubtedly Eisenhower, a joint decision made by Britain and the United States, and at the same time a concession by Churchill to Roosevelt...... Most of the equipment and supplies of the British army came from the United States, and now the United States is even willing to directly send troops to participate in this war, which can be said to have nothing to do with the United States, and Britain must give the United States a little benefit no matter what.

As a result, the Joint Chiefs of Staff Committee appointed General Eisenhower as the Supreme Commander of the Mediterranean Theater, and Alexander, who commanded the Dunkersk retreat and was known as the "escaped general," as the Supreme Deputy Commander of the Mediterranean Theater.

But in fact, the Allied command was not in the hands of Eisenhower or Alexander, but the command was in the hands of Montgomery, commander of the British 8th Army.

The reason is simple: Eisenhower, the supreme commander-in-chief, had no actual combat experience, and Alexander was a man of fame...... The Great Retreat of Dunkirk was not strictly a battle, but on the basis of the mistake of the Germans, that is, the failure to attack in time, the mobilization and organization of British ships to bring the British rout back to England.

The success of this operation was indeed of great positive significance, as it preserved hundreds of thousands of combat experienced living forces for Britain.

But the problem is that Alexander can be replaced by any general, and he is afraid that he can do this.

That's not to say that Dunkirk isn't great, it's actually great, and it's a very difficult task to evacuate hundreds of thousands of people in a few days.

But it was not Alexander who created this greatness, but the countless British civilians who had no combat experience or common sense, but volunteered to sail their fishing boats to Dunkirk again and again to rescue the British soldiers.

As for Alexander's actions in Burma, it goes without saying...... The equipment and strength are superior to the Japanese army, and there is the assistance of China's elite troops, but in order to escape, he deceived the Chinese army again and again to be the rearguard, and the other side ordered the British army with advanced equipment to flee for his life, and finally failed to escape and was surrounded by the Japanese army, if it were not for the Chinese army desperately rescued, the British army would have been wiped out in Burma.

Alexander, on the other hand, was complacent about it.

Such a general who does not understand military affairs, as the supreme deputy commander-in-chief of the Mediterranean, of course, will not speak with much force.

The commander of the U.S. Seventh Army, General Patton, although he was an excellent general and had combat experience (Patton served as Pershing's adjutant in World War I), did not have the prestige to fight Rommel in North Africa and "drive the Germans back" to Montgomery, Tunisia.

So in fact, the Allies still had the final say, and a rather risky but innovative plan formulated by the British and American Joint Staff made Montgomery veto it and was stillborn.

"I think we can land from Messina!" General Patton said: "It is true that it would be very difficult to land in the port of Messina, for example, the Strait of Messina is very narrow, and for example, we will be flanked by the Italian army on both sides. But...... It is precisely because of this that we can be surprised. That is, because the enemy did not think that we would land in Messina at all, they were not prepared for defense in the port of Messina, and all the Italian troops were placed there, and even more so the less combat-ready units of the Italian army...... Gentlemen, the less combat-ready units of the Italian army, what kind of troops are they? All we have to do is wave the flag in their direction, and they'll come running and surrendering, and I'm sure they'll surrender much faster than they can charge!" ”

There was a burst of laughter in the conference room, and General Patton, who had always been known for his vulgar speech, was an eye-opener for the English gentlemen.

However, there is a saying that "rough words are not rough", although Patton's words were vulgar, but they were a snake and a seven-inch attack, and this plan was not only "unexpected" for the German and Italian troops, but more importantly, once the landing was successful...... The whole of Sicily lost contact with Italy, like the most important seven inches were pinched by the Allies.

However, Montgomery certainly would not agree to this tactic.

This is not only because this tactic is not in keeping with Montgomery's usual cautious use of troops...... In fact, it is not a big deal, Montgomery is cautious, but he will still be dangerous at extraordinary times.

So the most important thing is ...... This is the plan proposed by the American Patton.
