In order to ensure that in 1916, the Allies would not suffer any losses on land, the Allies transported materials to the UK at all costs, and even sent out an escort fleet of more than imagined for these materials. In a short period of time, they curbed the attack of the sea wolf, but the backyard caught fire. The 50 merchant ships, not many compared to the previous 200, were already quite large for the American routes.

South America is also very important to the United States. The materials obtained from South America are calculated as an important direction for American raw materials. Once attacked, one-tenth of the United States will have difficulties in obtaining raw materials, which will affect the United States' industrial production and total volume.

Unfortunately, no matter how powerful the Allied Power is, it is impossible to escort both sides. Especially for South America routes, there are too many branch routes, and it is very difficult to escort. After weighing the pros and cons, the United States made a difficult decision to reduce shipping from the East Coast. Anyway, the United States has a large railway connecting east and west, and both sides are surrounded by the sea, which can be compensated from the West Coast.

This is indeed a good way. American merchant ships can be transferred through the Panama Canal, but submarines cannot chase into the canal. Submarines can hide themselves with the help of the sea, but there is no way to hide in the canal. If you think of the west coast, you either dove from the southernmost end of South America or send new submarines from the country, it is almost impossible for Deng Jieqian to get involved in this aspect.

After the United States reduced its merchant ships on the East Coast, Deng Jieqian reduced its operations and continued to spread into the North Atlantic. Now, relying on the help of a small number of reconnaissance aircraft, they chose some ships with not so strict escorts. Unfortunately, there were not many opportunities like this. With the efforts of the Allies, the number of sinkings decreased greatly from 1.5 million tons. Sometimes only two or three ships were sunk a day, and sometimes even one was not.

Such a dull situation made the Allies breathe a little relieved. If German submarines can still attack with their higher-level protection, it would be really troublesome. They did not know that although submarines reduced their actions and seemed to be restricted, they were actually covering up another action.

The powerful escort of the Allied Powers is not undealtable. If the submarines are even raided, they can severely damage the escort fleets. Unfortunately, they are useless. The main force of escorts is destroyers. Such ships have been focused on production since the United States began to focus on production, and the output has been increasing continuously. Since 1915, there have been as many as 600 destroyers delivered and used. These destroyers have not even been used all of them. This is also the foundation of the Allied Powers. Whether it is warships or those who operate warships, they are much stronger than Germany.

It is impossible for a submarine to attack for forcibly, and it is at a disadvantage to destroyers. Forced attack may cause losses. Deng Jieqian came to take revenge and calm the Allies' suppression of the Allies. Every warship and every human hand is very critical. It is impossible to waste it here for no reason. Choose a safer method as much as possible.

However, after the submarine sinking rate was greatly reduced, the German General Staff proposed a combat plan, using reconnaissance aircraft to detect the concentration of British materials, and then took advantage of Germany's advantages in airships to launch a sneak attack on British warehouses.

Deng Jiegan is a navy and does not understand air combat. Fortunately, the airship officers who once supported Germany were still there and were still helping Germany train airship personnel. He was also lit up when he heard this idea.

It is definitely impossible for the materials transported from the United States to Europe to Bordeaux directly. It is not a war zone. Some cannons have a range of more than 20 kilometers. If they encounter a large gun shell when unloading in the harbor, there will be problems with the ship and the materials.

Only by unloading goods in the UK, storing them, and then passing through small merchant ships, Germany had thought of using airships to raid, but Britain made a lot of camouflage, and from the hands of the United States, the Allies ordered a large number of airships. Although Germany currently has the largest airship legion in Europe, with more than 700 large airships, the UK also has 250. Perhaps it is impossible to come to Europe and support combat, but it is enough to allow Britain to defend the British sky.

However, if there is a certain and extremely accurate map, airships can also use sneak attacks to set off at night, and accurately bomb the warehouse with the support of ground forces in the early morning, and then leave. As long as they are kept confidential enough, they will have 40 minutes to 1 hour.

This kind of special bomber at a fixed point has very high intelligence requirements. Before, it was impossible to investigate the British warehouse in depth. After owning the reconnaissance aircraft, there was no problem. The reconnaissance aircraft not only had a large range and fast speed, but also had equipment specifically used for reconnaissance, which was enough to complete this task.

It took the German General Staff three days to improve the entire combat plan, and then negotiate with the reconnaissance forces.

After asking for instructions from the country, the reconnaissance force finally agreed to the German request. After all, under the premise that the Allies strengthened their escort forces and Deng Jie's cadres were unwilling to fight with the Allies, the role played by the reconnaissance aircraft was reduced. Although two or three large-scale ships can be provided every day, these ships are all large ships with more than 100 merchant ships, with escort forces of up to 60 ships, with several layers of protection, and any movement will be reflected and throwing deep-water bombs unreasonably. In this case, even if Deng Jie's cadres can enter perfectly, it is impossible to kill 60 escort fleets in a short time, and there will be some losses at some point. Therefore, these Information has no effect. Occasionally, there will be some small and low-escort ships, and they will choose to pass quickly on remote waterways at night. In short, the role that Deng Jie can play is quite limited. Instead of doing this, it is better to support the airship. This is also a reconnaissance. However, it is not too difficult to switch from sea to the British Isles, because weapons that can deal with reconnaissance aircraft have not yet appeared. During reconnaissance, the reconnaissance aircraft will not drop below 10,000 meters during reconnaissance, which eliminates the attack of anti-aircraft machine guns. As for airships, only at a speed of about 70 kilometers per hour, the maximum ceiling is rumored to reach the height of the reconnaissance aircraft. Such things are not threatening to reconnaissance aircraft.

In the next week, 72 reconnaissance aircraft conducted reconnaissance on the UK in batches. Since the UK is closer to the airport, the British Isles are not big, and they did not search every inch of the British Isles in a carpet-style search. The German intelligence agencies still obtained some suspected targets. After expanding the scope, they finally listed 24 targets. These reconnaissance aircraft mainly focused on these targets.

In fact, reconnaissance aircraft has a great effect. 60 of the 72 aircraft are constantly reconnaissanced 24 important locations almost during the day. High-speed cameras can take 1,200 high-definition photos every day. In order to support European army operations, the UK's warehouse cannot be small in size, hidden transportation and storage, and it is impossible to see flaws every moment under long-term monitoring. Whether it is transported in or out, things are obvious targets on high-definition photos.

Tens of thousands of photos are fed back to the General Staff Department every day. The General Staff Department organized at least 1,200 young staff members to look at the photos specifically and look for clues from these photos. In the end, 8 goals were confirmed among the 24 goals. Among the 8 goals, 5 of them were non-weapon targets, mainly auxiliary facilities such as logistics supplies, food, clothing, tents, etc., and the remaining 3 were the most important arsenal.

In order to support the operations of millions of troops, especially in winter, the army in Bordeaux was strengthened. The three arsenals were extremely large, each of which was enough to equip more than 600,000 people. Especially now, a batch of new weapons have been added, which has filled the arsenals. Especially under the threat of German submarines, the Allies gritted their teeth and used massive escorts to send a large amount of supplies to come and temporarily placed in the arsenal. In the future, when the right opportunity is waiting for the right opportunity to break these weapons into pieces, they are sent to Bordeaux in small boats.

The English Channel is the narrowest position, only more than 30 kilometers, and fast merchant ships can pass in 2 hours. Even the German high seas fleet has an absolute advantage and blocked the English Channel, there is a certain chance to send things to Bordeaux, not to mention that now, the two sides are just forming a confrontation in the Baltic Sea, and there is no way to affect the English Channel for the time being. This place has become a key contact between Britain and France. After a large amount of materials are sorted and transferred through the UK, they are transported to Bordeaux to support the modernization-level war.

The three locations were extremely clear, and it took another 3 days to clarify the surrounding topographic map, reference objects, and even the route of action. In the staff, there was even a model of top view and comparative structure for the precise design plan. After at least a thousand people discussed and hundreds of modifications, a relatively mature plan was finally formed. The whole of Germany would concentrate all airships at night, go to the UK in a detour, take the most remote route, strive to reach the two target areas around 3 o'clock at night, and then have 30 minutes of free play. Regardless of the final effect, they must leave as fast as possible. The newly formed anti-aircraft machine gun air defense force in Germany will respond on the way back. For the British's reaction, they made at least 12 reaction plans, and while escaping, they also prepared for attack.

All of the things are strictly confidential. Except for some German generals, all the young staff members who participated in the plan to modify the plan were almost limited to freedom. In the specific areas of the staff, they were not allowed to go home or contact the outside world. They almost made the confidentiality the best. They were all waiting for the moment when the plan was going on. (To be continued.)
