In the blue Atlantic, in winter, the waves are a little bigger, a 17,000-ton ocean-going cargo ship is moving at high speed, it is docked at a private cargo ship of the British shipping company, loaded with 50,000 rifles and various guns and ammunition, enough to equip 3 divisions of munitions, is just made by the American munitions factory, choose him such a fast cargo ship to transport to the United Kingdom, the reason is that this ship, it can sail at a speed of about 18 knots.

Since the beginning of the war, the spring of ocean-going cargo ships, especially fast ocean-going cargo ships, has arrived, after all, it is at least 50% faster than other ships, or even doubled, and others may take half a month to arrive, it can run a trip in 10 days at most, and fast cargo ships are very competitive in the moment of war when every second counts.

Habernard stood at the bow of the ship, he liked this feeling very much, the sea breeze blowing, watching the bow cut the waves, the cargo ship moved forward rapidly, every minute, every hour, every day, it represented closer to the point, the golden pound, seemed to beckon to him, he this month, has been the next 3 pounces of business, the price of goods and subsidies have increased tremendously, according to this, at most one and a half years, he will be able to recover the cost, and then buy a cargo ship, in that case, you can complete the rapid accumulation of capital.

Unbeknownst to Haberner, the sea wolves were already staring at him as he was moving towards the future. A single cargo ship, as early as 20 nautical miles away, was spotted by the sea wolf pack, and after confirming that there was no escort, one sea wolf was left to deal with him, while the other six pounced on another target, the two in front. The distance is less than 30 nautical miles, and behind it is a fleet of 30,000 tons of cargo ships. The tonnage is much more than that, and the transportation is some cloth and basic industrial materials. Relatively speaking, it is more important and the results are higher.

In the plan of the General Staff Headquarters, all the cargo ships were divided into several grades, the military side was the highest, which could directly enhance the combat effectiveness of the British army, and for the German side, the threat was great, some raw materials and military materials related to the military industry. It is the second class, and as for the material and ordinary security of the third class, from this aspect of the calculation of military merits, up to a certain level, you can issue a certain medal, or even a promotion level.

Of course, if there is a precious metal, it is super-grade, which will attract most of the sea wolves. Even Boer could not refuse to capture it, after all, at a time when the value of precious metals such as gold was very high, it could be traded as a homogeneous currency on the international scale. Is it much better to capture than to sink a ship, take this 17,000-ton cargo ship, even if it is to transport 5,000 tons of silver. It's enough to make people blush.

Seven submarines, just like that, in a vast area of more than 200 nautical miles. To attack, the first to attack. Next to the Azure, the SMU74 submarine.

At 9:20 a.m., the 17,000-ton Azure that was advancing in the originally calm route, the alarm bell suddenly sounded, the ship was military supplies, there were 100 army soldiers escorting, and the soldiers who were responsible for protecting the deck suddenly found the traces of torpedoes, one of them rang the alarm bell, and all the army soldiers came out, and some also shot at the sea.

Unfortunately, the matter was irreparable, and when the torpedo was found, the torpedo was less than 150 meters away from the ship, and at this distance, the torpedo running at high speed was insoluble in front of the cargo ship without self-defense firepower, and no attack could change the fact that the ship was hit.

A 450-mm torpedo, after a minute or two, hit the cargo ship, not only hit the center of the ship, but also blasted out a large hole of more than 3 meters below the waterline, the solid hull, although it blocked the explosion of the torpedo, did not break into two because of the torpedo, but more than dozens of tons of seawater per second, or let the cargo ship capsize quickly, this is a cargo ship, not a warship, there is no certain management damage.

In despair, Habernar almost watched his ship be hit, even sunk into the water, and his futile cries out, not only did it not help, but the ship sank inch by inch into the water, including him, a shipowner who might have a future of infinite money.

The sinking speed of the Azure was too fast, so fast that when he was silent, there were people who were rushing to dive around, and less than 15% of the personnel escaped from the whirlpool of the wreck, and the rest followed the Azure cargo ship and sank to the bottom of the sea together, including the owner of the Azure who once wanted to continue to expand production and obtain huge rewards.

The sea mercilessly swallowed up a 17,000-ton fast cargo ship, but nothing changed, the north wind was blowing, and the waves were still so choppy.

One hour later, 30 nautical miles away, another channel, three 13,000-ton cargo ships took over, because of some modifications, these ships have some guns of about 100 mm, enough to deal with a huge part of the pirates, high-speed cargo ships, just as the sea wolves surrounded them in the encirclement, when six sea wolves, in different positions, fired torpedoes at the cargo ships, the result was already doomed.

None of the ships were able to run out, and even sank faster than the previous Azure ship, and several of them were hit by 2 torpedoes, which were directly reached by two sections by the huge torpedo.

More of the people of this fleet did not run away, and sank into the icy Atlantic with the merchant ships, and even if the rest, if they could not be rescued in a few hours, the icy Atlantic would let them know the power of nature.

In naval battles, most of the casualties who fell into the water were not drowned, many people who jumped down, and there was also kung fu to get a life jacket, but in the Atlantic Ocean in winter, the water temperature was extreme, and there was no need to keep warm, the humid and icy sea water would continue to extract the heat on the human body, and finally most of the heat was pumped away, and they were frozen to death.

Eventually, when the battle was over, the Fourth Squadron targeted 15 of the 17 targets, and the other two escaped during the day, taking advantage of the darkness of the night, out of the range of the Wolves' cruise, and by the time the Fourth Fleet found out, they had escaped 120 nautical miles.

120 nautical miles, is not a particularly long voyage, especially those two ships are not fast cargo ships, if you pursue, at most 20 hours, you can catch up, Alto was originally ready to catch up, but from the far sea fleet, a new order came, had to give up, compared to the escape, the new mission, more tempting, more tasty.

This time lasted 27 hours, 370 nautical miles before and after, across a wide range of maritime operations, and finally in the afternoon of the next day, the successful end, the fourth squadron achieved a complete success, 7 submarines, a total of 107 torpedoes, at the cost of no damage, finally sank 43 ships, close to 310,000 tons of displacement, on this point, the British maritime transport industry was hit hard, the total number of British merchant ships in this era, is only a few million tons, this time, That's almost one-twentieth of that.

You must know that the current shipbuilding capacity of the whole United Kingdom, excluding the production of capital ships and warships, is only how much a month, and this number is far greater than the number of a month, and even the merchant ships launched in half a year or a year may not be so large.

In the First World War, Germany's infinite submarine warfare in 2 years only sank merchant ships with a total tonnage of 12 million tons, but in such a short day, it was more than 300,000 tons, which was only a detachment of 7 submarines, and the Seawolf was far from reaching the level of 100, or even 200 submarines in the plan, why is there such a big difference.

In fact, in the First World War in later generations, the sea wolf played well, did not play the real role of the sea wolf, those ships are acting alone and on various routes, many times, their battles are a kind of luck, in the loitering and patrol encounter, encountered, that is good luck, but most of the time can not be encountered, even if it does, many times, it is necessary to determine whether it is a British ship, and even sometimes, because of the sinking of the cruise ship, it will cause some incidents, the United States will use this as an excuse to protest, The German blockade of Britain could not be sustained, and instead the Sea Wolves were pushed deep into the Mediterranean without American ships.

And now, the accurate and unmistakable intelligence has given the sea wolf the right guidance, and the sea wolf does not need to wander aimlessly on the channel, choosing the opportunities that may be encountered, which will miss many opportunities. With the support of strict intelligence, in the area controlled by their respective detachments, a series of attacks on ships on a fixed route can finally achieve extremely excellent results, and this 27-hour operation is a very simple example.

The attack of the sea wolf came to an end, today was a bumper day, there were about 3 similar detachments, they were all constantly attacking British cargo ships, in just 15 days, a total of 1.25 million tons of British cargo ships were sunk, almost 90% of the cargo passage from the United States to the United Kingdom.

The operation of the sea wolf, with a cycle of 5 days, 5 days of fighting, 2 days of supply and relaxation, in the huge North Atlantic, Germany secretly established 7 submarine supply bases, plus some ships hanging neutral countries, and even South American countries to replenish, the sea wolf was able to maintain a strong fighting spirit almost every day, and these, gave Britain a huge blow, the chains tied to the necks of the British, it seems to be constantly getting worse, half a month of supplies and supplies, just a foundation, and then, when the chains are getting tighter and tighter, It's going to be fatal.
