Then, in the French West Indies, the local French fleet was disarmed, and the crossbow operation achieved a successful success in both areas.

However, this did not satisfy the British Navy.

The Port of Toulon is located in France, and the British navy has no choice but to fight for it, but the French navy in the French North African colonies can be won over!

June 5th, early morning.

There are not many waves in the Mediterranean.

Due to geographical location, the Mediterranean is often not considered a sea, but a bathtub. The countries along the Mediterranean coast have absolute control over the Mediterranean. Specifically, France and Italy are definitely pioneers.

Reflecting on the construction of warships, the specifications of their naval ships are often formulated based on the sea conditions of the Mediterranean.

The night is quite quiet, the weather is very good on this day, and the sky is extremely clear, and you can see stars blinking.

The night will provide quite good cover. At this time, in the night, a submarine is sailing in a floating state.

The submarine u73, a submarine secretly passed through the Strait of Gibraltar and sneaked into the Mediterranean Sea half a month ago.

Now, the Strait of Gibraltar is still under the control of the UK. In order to ensure the interests of the Mediterranean, the British set up layers of monitoring devices. As long as there is engine movement underwater, they can discover it and then launch an attack.

Unfortunately, the British did not know that the German Navy had long mastered the sea water characteristics of the Strait of Gibraltar.

Since the Mediterranean air is controlled by the current flow direction of the subtropical high pressure zone and the precipitation is light and the evaporation of rain, the salinity of the Mediterranean sea water is higher than that of the Atlantic Ocean and has a higher density, but the Mediterranean sea surface is lower.

In this way, a density flow is formed in the Strait of Gibraltar. The sea water flows eastward from below the water surface to 400 meters, and the sea water flows westward from below 400 meters, which forms a density flow.

This density current is simply prepared for the German Navy. When their submarines dived out of the Mediterranean, they turned off the engine and descended to a deeper area below the sea surface, flowed out of the Mediterranean to the Atlantic Ocean along the ocean current. When they came back, they lifted the submarines to a shallower area, turned off the engine, and flowed back to the Mediterranean along the surface current.

As long as you don't develop your motivation, you will be as quiet as a fish.

Of course, they are much more convenient now. With France's surrender, they can find a port in southern France to dock at any time, and the sea rights of the Mediterranean will soon fall into the hands of the German Navy and there is no need to enter and exit Gibraltar dangerously anymore.

Moreover, what they didn't know was that the Strait of Gibraltar had long been on the Cialis' list of attacks, and it was just a matter of time.

Now, the u73 submarine is in the air.

Now, German submarines have installed snorkels, which do not need to surface. As long as the snorkel is exposed, the diesel engine can be started for navigation.

However, it is very uncomfortable for submarine soldiers to stay in small submarines often, so whenever they have the opportunity, the submarines will still float up and let the submarine soldiers alternately go to the bathtub above the command tower to breathe.

In fact, during World War II, submarines were still floating for most of the time, and they only switched to submarine after discovering prey.

And now, in the bathtub, sailor Lucas was breathing the fresh air mixed with the sea breeze.

In a submarine, even if there is a snorkel, the air that is mixed with the smell of diesel is very uncomfortable.

The top of the command tower, also known as the bathtub, is because when the waves are big, the sailors here are often wet, and in the Atlantic Ocean where the waves are rolling, this is common.

However, it is rare in the Mediterranean. It is more like a gentle girl, every move and a wave, all of which are so elegant.

Everyone had only two minutes, and was also responsible for monitoring the surrounding sea surface. Just as Lucas had just breathed a breath of fresh air, his brows suddenly frowned. His eyes looked at the dark sea surface in the distance, with a little light shining on it. His ears stood up and listened carefully to the roar of the engine in the distance.

"Discover a fleet!" Lucas shouted loudly, "just at nine o'clock in the direction of ours!"

"Quick, battle alarm!" With Lucas' notification, Captain Helmut immediately issued an order.

Several people in the bathtub ran down quickly, and finally Lucas closed the hatch, which was a very common move, but it was the most important one.

In battle, everyone's nerves will collapse tightly, and at the same time, various accidents may occur, such as forgetting to close the hatch.

This is not without precedent. Some submarines once forgot to close the hatch, but they never came up again after an emergency dive.

And now, German submarine soldiers are the most well-trained, and they will never make any low-level mistakes!

"The first ballast tank is filled with water, ready to dive, raise the snorkel, periscope, prepare to switch to the battery, and the diesel engine stops." Helmut issued one battle order after another.

If you look from outside, you can see the bench of the submarine sinking rapidly. The bench rolls a few waves and then falls into the sea. Then, the command tower.

When the command tower was infiltrated into the sea, the ventilation pipes on the side of the command tower were slowly erecting, while the periscope stretched out from the middle.

The vent pipe does not provide air to the diesel engine, but provides fresh air to the submarine. When the submarine attacks, it needs to turn off the diesel engine.

Because the diesel engine is too noisy, with the continuous development of underwater sound listening technology, the noise of the diesel engine will be very far away.

However, the energy of the battery cannot be compared with that of the diesel engine. When the battery is used, the speed will decrease.

Helmut's eyes stared at the periscope. Now, he could only see everything on the opposite side with the help of the moonlight. His hands turned the periscope and looked at the other side's fleet. He couldn't help but say something in his mouth: "We found a big fish, the torpedo tube on the head of the boat, all loaded, fixed depth of 10, ready to launch!"

The opposite side is definitely the main force of the British Navy in North Africa! The British finally dragged out their colonial navy!

During the other party's navigation, Helmut saw two tall warships that were straight through the deck, which were the British aircraft carriers! Although he couldn't see clearly, Helmut could also guess that it should be the British aircraft carrier Eagle and the Hundred-Eyed Giant aircraft carrier.

If only one can be killed!
