The North Atlantic, which was a busy shipping lane, was now a place of fighting between Britain and France, and the entire German submarine was sent here, whether it was a newly built ocean-going submarine or a previous one, divided into different areas and teams, and hunted the British merchant ships here, with great success.

Since there is hunting, then there is countermeasures, for the British, the British have been in the naval field for many years, technical reserves and various tactics are very much, although the appearance of submarines, so that the British were caught off guard, but the British still from the submarine warfare, gained a lot of experience.

Underwater listeners, from the laboratory, were urgently put into actual combat, although it is still the noise of the seabed, but after strict training of the listeners, especially some with special abilities, they can hear the sound of the propeller from the complex and changeable underwater clutter, especially the propeller of the German Navy, which is slightly different from the propeller of an ordinary battleship, after more than 10 days of special training, these special listeners, for this sound, more sensitive.

Although there are still problems, but this, most of the problems have been solved, Britain is no longer without resistance to underwater submarines, when 12 special listeners go to the post, the confrontation between Britain and Germany, from the absolute disadvantage of Britain, to the extent that it can be confronted.

The guerrilla fleet, headed by 12 listeners, began to be active in the seas, and a cruising fleet of more than 100 heavy, light and destroyers began to hunt and kill German submarines.

I have to say. For submarines, the greatest protection is always the sea. Before, they were hidden in the sea, unless an active attack was exposed, otherwise, even if there were tens of millions of tons of warships, there was nothing they could do about it, so they had to defend passively. But now, with this listener, although the accuracy is not high. There may be 10 discoveries, at most one or two real discoveries, but under this odds, the unsuspecting German submarine forces. Immediately suffered a big loss.

Time of day. On the first day of the listener's post, the figure of sinking 12 ships was obtained, which is evidenced by fragments, but in fact, on this day, the Germans lost not only 12 submarines, but a full 16, and did not calculate 4 submarines. It was because the submarine commander chose to sink in order to avoid depth charges.

Although it is only a little more than a thousand meters deep. However, after the sinking, due to various reasons, these submarines could not be re-raised, and they were suffocated alive.

In a short period of time, such a big loss, the commander of the far sea fleet, Bohr, was also very anxious, through the investigation of the pervasive intelligence agency, but unfortunately the British side, for the protection of the listener is quite tight, but the British side has the ability to detect underwater submarines.

The concealment of submarines has been greatly reduced, although I don't know how reliable the British side is, but there is a fleet escort, especially a large fleet escorted by destroyers, it is not suitable for hands-on, Bol is worthy of being an excellent commander, he quickly changed the order, the submarine force, no longer set off in clusters, they dispersed into a separate fleet, scattered to the depths of the ocean.

From a group attack to a solo operation, this increased the difficulty of the British to explore, and even if it was detected, only one would be lost, and it could even warn other submarines to stay away from this British convoy with the ability to explore.

I have to say that this trick is very old-fashioned, originally, there are fewer specially trained listeners, and the reliability is not high, these people are selected from countless personnel, layer by layer, the level is extremely high, and they may be weaker, if they continue to cultivate, there will be excellent emerges, and the time will be prolonged, at least half a year, that is, in half a year, the British may count on these 12 people, the North Atlantic, this huge ocean, on the waterway, there are many places that can be ambushed and attacked, and every group of ships must be escortedIn this way, the cost is extremely high, and the huge number of British fleets cannot bear it.

Submarine warfare and anti-submarine, this is a battle between the two sides, Pol's moves, although in a short period of time, the number of sunk cargo ships, down to a low value, but there are still several ships sunk every day, which is still a loss that Britain can not bear, from the beginning to the present, more than 2 million tons of merchant ships have been sunk, these have not been replenished, still tens of thousands of tons per day, a month, it is another million tons, especially before, the United States will send ships to transport, However, when the United States began to prepare for war, it seemed to deliberately reduce the irritation of Germany, warning its ships that the North Atlantic route was dangerous and that the U.S. government would not be responsible if there was damage.

For a while, the newly restored capacity was hit to the bottom again, and the German submarines, really like swimming fish, were elusive and fixed cruises in the North Atlantic, and they were increasingly unable to catch each other, sinking 16 ships from the first day, and only 7 submarines were achieved in the following half a month, and at the same time, the number of submarines in service on the German side exceeded 30.

The 1500-ton submarine, among the submarines, is considered a big ship, but in the field of warships, he is not at all, some destroyers with a larger tonnage, it exceeds this tonnage, after obtaining part of the technology of the Northwest, especially the battery pack and main engine are produced by the Northwest, the Northwest is only in a month, the supporting battery pack and main engine more than 300 sets, the rest of the hull, internal construction, weapon configuration, for the Germans, is nothing, A dock of one or two thousand tons can be built at will, and as for the personnel, after vigorously cultivating the submarine force, all kinds of targeted short-term training have also emerged in an endless stream, and Germany has definitely been able to fight for consumption.

Submarine warfare and anti-submarine warfare have become a war of attrition, which made neither Britain nor Germany expect that the exchange ratio between merchant ships and submarines has been maintained at 10:1, let alone 10:1, even if it is one to one, this exchange ratio is not something that the British can afford. Strive to let them serve as soon as possible, on the other hand, they can only wave money. Buying merchant ships from all over the world, for a time, the price of merchant ships has risen to a certain height again under the situation that has skyrocketed.

And there is a striking resemblance to history that the Jiangnan Shipyard also received orders from the British for high-speed merchant ships. That's 21 at once.

For this huge order, the personnel in charge of the Jiangnan Shipyard were slightly hesitant, as the top level of the Northwest government. It is not a secret to him that the purpose of the North-West is in favor of the Germans, it is a fact. Whether or not to reject the order. Not to some extent supported the Entente.

When this idea was reported to Yang Yuanzhao, Yang Yuanzhao smiled, yes, the Northwest supports Germany, and even if it is possible, it will stand on the side of Germany, but it does not mean that the Northwest will not do business. The United States supported the Entente and was even ready to join the Entente. But after the outbreak of the war, the Americans continued to do business with Germany.

If there is money to be made, why not do it, the Northwest has always been jealous of the huge orders of the Entente, but unfortunately those orders are all Americans, even if the Northwest has a fast production speed and low quality, but in the relationship between countries, in the era of war, price and quality are the most insignificant conditions, and political interests and influence are the most important, which is also the basis for the United States to obtain a large number of orders.

It is precisely because of this understanding that the Northwest did not care much about it, nor did it actively expand the orders of the Entente, but now, in the face of the lack of productivity of the allies and the urgent shortage of Britain, the merchant ship orders were placed here, which was also a choice that Britain had no choice, which made Yang Yuanzhao see the opportunity, in the future, with the deepening of the war, the number of military orders will be more and more, and it will be larger and larger. Then the Northwest will become a natural choice, which is a wealth delivered to the door.

Yang Yuanzhao's direct order agreed to this order, and on this basis, he made contact with the British.

When Jiangnan Shipyard did this, it found that the British seemed to have been prepared for a long time, and on the basis of the merchant ship order, they placed a batch of orders for military supplies, the amount was not large, 2 million pounds, but it involved many categories, almost including the areas of northwest advantage. Military uniforms, bedding, shovels, tents, military food, field meal kits, the amount is quite huge.

The war has been carried out to this extent, both Britain and Germany have realized that this is a protracted war, what is the protracted war, is the economy, is logistics, is the overall war mobilization capacity of a group, in this case, it is impossible to put a country with huge industrial production capacity in the northwest, but the British are not sure how much the Northwest and the Germans are involved, whether it is a secret ally, or unilateral commercial cooperation, because of many moves in the northwest, It proves that the relationship between the two is based on unilateral commercial cooperation.

It just so happened that the German submarines sank a large number of British merchant ships, with the cruising fleet and the escort fleet, the Germans reined in slightly, and at least a few fixed routes were relatively safe, but the British lost a large number of merchant ships, although they bought a batch at a high price from the Americans, but the gap was still very large, for this reason, the personnel of the Ministry of Commerce almost ran all over the world, and got the reminder of the ancients, they found that it turned out that in the Far East, the Jiangnan Shipyard could produce 10,000-ton fast merchant ships, and the quality was very high. Swire has ordered a few ships, which are relatively cost-effective.

On the one hand, there is a real need, on the other hand, the British high-level also wanted to take this opportunity to test the relationship between the northwest and Germany, and almost both sides had the idea of contact, and the initial order was placed, 24 million pounds of merchant ship orders, 2 million pounds of exploratory military supplies orders, and so on.

These things, itself are produced in large quantities in the northwest, almost at the same time as receiving the order, when the advance payment is received, the keel is immediately laid down in the Jiangnan shipyard, as for military supplies, Shanghai itself has a large-scale warehouse and freight yard, and a part of it is mobilized from the middle, and it can be loaded immediately.

Of course, the northwest is only responsible for sending these materials to the Suez Canal, and the next is the responsibility of the British, cash on delivery, there are a lot of merchant ships going to Basra, and going to the Suez Canal is just a turn, from the Persian Gulf side to the Red Sea, hundreds of nautical miles more roundabout, and the reward is not small, just a few merchant ships, more than a week, it will be transported over.

Such a high efficiency was completely unexpected by the British, who found that they had underestimated China's industrial production capacity, thinking about the Chinese manufacturing in the global market, which had awakened and was no longer ignorant, and seemed to have unimaginable strength.

Military personnel, in the Suez Canal, inspected the goods, and found that the quality of the goods is very high, all of them are first-class, and the price is slightly lower than the price of the order issued to the United States.

However, the military order is very important, not the War Department can decide, in the end, or let Prime Minister Henry look at it, Henry weighed many interests, the United States can not be offended, there should be an order, at least to feed the United States, in order to pull the United States into the chariot, as for the northwest side, you can also increase a little, any country, industrial production capacity, there is a limit, this number is fixed, the British side from the middle of the more drawn, the German side is naturally less, this is also a certain level, Weaken the power of Germany.

Perhaps the military strength, Britain is not Germany's opponent for the time being, but than rich, occupying the world hegemony for hundreds of years of Britain, hundreds of years of accumulation, the total wealth it has, is not Germany can compare, the pound sterling as the world's main currency, is the basis of the world's finance, but the issuer is the British government, this is an innate advantage, soon, the next order was placed, the total amount almost exceeded the previous merchant ship orders, Linlin's total almost 50 million pounds.

This is not a small piece of fat, with the current soaring price of military supplies, the profit has reached almost 7 percent, and the British did not calculate, the industrial production capacity of the northwest has already surpassed the United States, the total amount is more than double that of the United States, the orders of the Germans, simply not enough to feed the northwest has already adjusted the wartime economy, a little adjustment, on the part of the order, and smoothly sent the order, sent to the Suez Canal, completed this transaction, as for the pound sterling obtained from the transaction, the northwest did not stay longer, after the First World War, The major currencies of the world are devalued, some of them are exchanged for gold, and some of them are purchased locally for raw materials and ores produced in India, which are the real wealth that will not depreciate.
