Before the deadline for launching a landing operation against the British, the No. 3 submersible tank, which was a new weapon of the German army, conducted a small-scale secret mock landing exercise on the island of Pearl, northern Germany, in order to improve the victory of the war.

The sea at the location of the exercise was not calm, the waves were getting bigger and bigger, and the sound of "rumbling" was constantly heard in the distance.

Three nautical miles north of the coast of Pearl Island, three German battleships lined up in a row. The rolling waves roared against the battleship's hull, giving off a chilling crashing sound.

Although Reinhardt's choice of landing site was an area that the British had neglected to guard. However, the Allies still took out Germany, France and Italy this time, a total of 9 battleships, 2 shallow gunboats, 16 cruisers, 45 destroyers, as well as 6 large aircraft carriers and 14 escort aircraft carriers, to form four fire support groups to provide naval artillery fire support for four landing beaches in the arc from the Thames to Portsmouth.

At the time of the exercise, because the Italian and French fleets had not yet arrived, the Germans used their three battleships to participate in this mock exercise.

The German Army, on the other hand, sent the No. 3 submersible tank to participate in the performance.

The modified No. 3 tank has extraordinary amphibious capabilities. Thanks to the tireless efforts of the young engineer Anderson, after taking over the task of refitting the No. 3 tank, he strengthened its diving capabilities, which allowed the tank to dive to a depth of 5 meters!

This exercise is also to prove whether the modified No. 3 tank does have such diving capabilities.

During the exercise, the German transport ship drove the No. 3 tank out of the ship with the assistance of the German landing soldiers at a position several tens of meters away from the coastline, and the No. 3 tank also smoothly used its excellent concealment and diving capabilities to advance normally in the water.

It wasn't until tank No. 3 exposed his barrel that the exercise soldiers of the wheelhouse guard spotted their tracks.

Landing on the shoal, the first thing that caught the eyes of the German drivers of the No. 3 tank was a seemingly non-threatening piece of wood, which was placed in front of them harmlessly, like lambs to the slaughter, waiting for the heavy armor of the No. 3 tank to be crushed.

According to Reinhardt's request, the content of all the exercises was not told to the participants in advance, and the purpose was to restore the reality and suddenness of the battlefield, so no one knew how many mysteries were contained in these woods.

According to the tank drivers, it seemed as if the wood was just an obstacle used by the British to block the landing force's bullets or to act as a cover, and if the German drivers did deal with it, they would be killed in the exercise.

Unfortunately, the vanguard of the No. 3 tank that participated in the exercise did not know the power of this kind of thing, so they directly passed over it and were eliminated from the exercise early.

One of the drivers of Tank No. 3 ignored the logs and rushed straight at them. Then, he heard the news of his exit on the communication channel.

It turns out that all of these woods are simulated to be installed with jumping mines, and once triggered, the explosion will kill the people around them. This is also very threatening to the tank, and those No. 3 tank drivers who do not believe in evil just now, if they encounter actual combat, they may suffer.

As for the clean-up of such mechanisms, the landing side of the exercise also found a trick, they used naval guns or aircraft carriers to carry out rapid bombardment, clearing one obstacle after another, until they were cleared, and the tanks could be on the road again.

Thankfully, the army, air force, and navy were closely linked during the exercise, and soon the bombers and naval guns cleared the way for the No. 3 tank, and the No. 3 tank was able to move forward.

After passing the level of jumping mines, the No. 3 tank was greeted by the anti-tank mines buried in the sand, the density of the anti-tank mines was so large that almost the entire sand was full of the shadows of anti-tank mines, and the fuses they exposed looked from afar like willow saplings artificially planted on the sand, and the density was so great that it could be imagined.

Of course, this is a simulation exercise that increases the difficulty. Placed on a real battlefield, it should be a little easier.

And according to what these German tank men knew about British anti-tank mines, they also understood that the power of such anti-tank mines was huge enough to pose a great threat to tanks.

Since they had never had experience in landing operations, their first wave of landing exercise troops were not equipped with engineers who could not clear these mines. In desperation, the commander of the landing party decided to send those small number of No. 4 diving tanks to take the lead and drive straight forward, hoping to use the losses of these tanks to open a way for them.

These No. 4 tanks have been baptized by anti-tank mines, and one by one they have also been declared out. So far, only half of the first tanks landed by the Germans have not yet been declared out.

After that, the surviving tanks became cautious and continued to move steadily.

However, this was not the end of the story, as suddenly, something resembling a door panel appeared in front of them, and the German soldiers found it difficult to reverse and leave when the tank hit it, as if the floor had been choked. At this time, the German tank crew in the tank had to find a way to get the tank out of it and continue to advance.

Looking back, on the beach of the coastline, the "wreckage" of the tank that stayed still was also densely packed. The position where the No. 3 tank fell into the striker was about 150 meters from the beachhead.

That is, it is almost impossible to rely on the German infantry to save those No. 3 tanks. Because until they get here, the soldiers of the landing side, will not have any cover. In other words, on this 150-meter distance, they all acted as live targets for the defenders.

Looking at the bombers of the two sides flying around in the sky, the German Army soldiers on the ground fell into despair for a while. Suddenly, they noticed that there was a huge circular pattern drawn on the sand, and the word crater was written in German - wasn't this a bunker!

Although there are differences from the real situation, these crater patterns are also simulated "temporary foxholes" created after bombing, and can be used.

In this way, the infantry will find cover and be able to move on.

However, because the difficulty of the exercise was deliberately raised, these areas with dense crater patterns were still too far from where the tanks had fallen, and the German No. 3 tank still could not pass through here.

What stopped them was that Reinhardt copied some of the local methods that the British had not been able to use in the first place, according to later historical documents.
