"If it is combined with the barrage blocking mentioned earlier, Your Highness, the purpose is to suppress the enemy, not to try to destroy them, and to disperse the attack with combat squads can reduce the dense killing of our side, and finally enter the enemy's defense line, clear the enemy army, and clear the way for the attack of the follow-up troops." is worthy of Schlieffen, and he can immediately combine with the barrage Xu Jin.

"After tearing the enemy's defense line, don't stick to it, this will form a salient on the battlefield, which will become a key area for both sides to fight, and then force us to continue to invest troops in this area, we should continue to attack, and the entry of the follow-up troops will tear the hole bigger and bigger, and finally completely cut off the enemy's defense line, and then we have a lot of options." Jochen is talking about a constant in World War I, which is the battle for the salient.

Because the appearance of the salient means that the originally straight defense line is bulging out, which means that the defender has to invest more troops in this area, so in order to reduce the number of troops on the defense line, they will try their best to eliminate this bulge recessed into their own defense line to level the defense line, and finally it will evolve into a large-scale battle around the salient, and in the end there are many more people who die than those who want to level the defense line and save money, and such a stupid thing Yochen doesn't want to repeat it.

"Yes, if we can tear through the enemy's defense line and enter depth, we can directly attack their large rear while their new defense line in the rear is still unstable!" Schlieffen said.

Although it was not possible to achieve a deep penetration in a war with insufficient mobility, as long as the defense line was strengthened after tearing the gap as Befalkingham did, the Germans could force the French to scramble.

"Not only that, but after we tear the hole again, in order to prevent their own back from being copied, the broken defense line must be re-flanked and face the line of defense to our torn hole, which will force them to continue to disperse their forces into the defensive line.

And we can change the direction of the attack and continue to tear in the new defensive line, so that we can continue to divide and cut off, and finally we can isolate the enemy in one grid after another, and then we can eat them one by one. Jochen offered another tactic.

This tactic can even be said to be more difficult in mobile warfare, and even more insoluble than the Great Depth Penetration, because it is constantly divided, constantly adjusting the flanks, and finally completely trapped in the square, except for a large retreat and rebuilding the defensive line in the rear, the enemy can only be completely eroded.

"Whatever the choice, the initiative is in our hands." Schlieffen added, and then exclaimed: "Your Highness, these ideas you said are very inspiring, and we will try and verify them." ”

"I am very glad that a little immature idea can help me a little, and then I will have to bother His Excellency the Chief of the General Staff to make a concrete attempt." Jochen was modest.

"It's my job." Schlieffen responded.

Maybe Yochen can still draw a simple tactical diagram of an infantry assault group, but that's just a schematic diagram, and how to really use it still depends on professionals to test and summarize, and he is a layman who doesn't mix it up.

At the same time, at the Royal Ship Technical Shipyard in Wilhelmshaven, director Hansen was taking a new designer to look at the experimental ships that the Royal Ship Technical Shipyard had built at its own expense.

"That's what you're building now? She's pretty perfect, what else are you calling me for? The emaciated man with the beard on his upper lip said with some discouragement.

He didn't understand, why did this shipyard come all the way from the United States to play tricks when it was already able to build ships that were better than his own design?

"Mr. Holland, you must be thinking that we are making fun of you by looking for you, right?" Hansen looked at the man in front of him and smiled and said, "Or do you really think she's perfect enough?" ”

"Isn't it? The gasoline engine provides the power for surface navigation, the electric motor provides the power for underwater navigation, and the gasoline engine can charge the battery of the electric motor in the surface navigation state. This dual propulsion system is much more complete and efficient than the steam-electric I envisioned, and I believe she represents the highest level of technology available today. Mr. Holland praised the design, which he considered to be quite good.

That's right, this Mr. Holland is that John Philip Holland, and in front of Hansen and Holland, the official Popper-designed submarine test ship.

Jochen had asked his personnel in Germany to look for Holland, but he was reluctant to come to Germany because he was going to participate in a submarine design competition held by the U.S. Department of the Navy, and Simon Lake declined the invitation for the same reason.

Jochen can only count on Pooper's all-rounder. However, Holland used a total of $150,000 in prize money to build the submarine Diver after winning the competition, but thanks to the bureaucrats of the U.S. Department of the Navy, they demanded that the submarine have surface combat capabilities.

Holland decided that it was impossible to meet this requirement on such a gadget, so he returned the funds of the U.S. Navy and terminated the construction of the Diver. And at this time, in the face of the Germans who came to the door again, Holland did not refuse. But when he came to Germany, he found that the Germans were already building submarines that were better than he had imagined.

The gadget, which is less than 20 meters long and has a surface displacement of less than 50 tons, is a toy in Jochen's eyes, but it is already well-designed in the eyes of a professional like Holland.

The gasoline-electric dual propulsion system is different from the Barracuda hull used in mainstream submarine design today, but adopts the hull of a ship that was more common in World War I and World War II.

The teardrop-shaped, whale-shaped, and cigar-shaped submarine shapes of later generations are not considered by Jochen because of the lack of electric welding technology and the difficulty of processing, and the more stable ship type is the best choice now.

The use of a BMW 60 hp gasoline engine allows the submarine to reach a speed of 9 knots when sailing on the surface, and a 40 hp electric motor allows the submarine to reach an underwater speed of 5 knots, which is already excellent in Holland's eyes.

Moreover, it has equipment such as conning towers, periscopes, etc., and does not have any surface attack weapons installed, except for two 380 mm torpedo tubes in the bow, which are in a state of readiness in the tubes, and have no reloading ability.

The performance looks good, but the underwater time is only 20 minutes, and the range is only 100 nautical miles when on the surface, so there is basically no practical use.

Hansen also said the same: "Mr. Holland, perhaps in your opinion, this submarine is already considered the best in the world in terms of technology. But she still can't meet the needs of the Navy. Too short range, underwater activity time, slow speed, and weak attack capability cannot meet the needs of the navy, and a ship that cannot be practical is not excellent.

You see, the cruiser under construction over there is the main work of the shipyard right now, and the continued improvement and development is the next focus of the chief designer, Mr. Pooper, who will not have enough time and energy to juggle the work on the submarine side.

Therefore, we need a professional submarine designer to continue to lead the submarine design and development work of the shipyard, and we think you can do the job.

The submarine project is highly valued by His Royal Highness the Crown Prince, so you can get the best technical support, the best working environment and, of course, excellent remuneration.

So we'd love to have you on board, Mr. Holland. ”

"Before I say yes, I want to know, if none of these submarines are sufficient, what kind of submarines will do, or what kind of submarines do you want me to help you build?" Instead of agreeing to Hansen's invitation, Holland asked what the Germans wanted.

"His Royal Highness the Crown Prince currently only wants us to carry out technical verification, and there are no hard requirements, but he said that if the watertight range does not exceed 2,000 nautical miles, and the underwater range does not exceed 50 nautical miles, then the actual combat significance of the submarine is not great, so I think the minimum standard is to achieve such a range." Hansen replied.

In fact, Jochen is all too small, he really wants to play wolf pack tactics, and the submarine does not have a range of more than 5,000 nautical miles and an underwater range of 100 nautical miles, so it is likely to be ignored by the navy because it cannot meet tactical needs.

Tirpitz himself once said: "The submarine is nothing more than a 'red herring,' a weak means that helps to defend the coastal waters and does nothing to balance naval forces." ”

Although this was not Tirpitz's intention, because during his tenure, Tirpitz presided over the construction of 198 of the 375 submarines built by Germany before the end of World War I!

Moreover, Tirpitz was a staunch supporter and executor of unrestricted submarine warfare, and even resigned in protest in 1916 because Germany stopped unrestricted submarine warfare, of course, the result was that Tirpitz, who had fallen out of favor, was sent out of favor by Wilhelm II. However, it can also be seen that Tirpitz himself did not ignore the submarine.

So he said this because Tirpitz believed that in order to gain sea power, he had to fight the British Navy head-on, and all naval resources had to be tilted towards capital ships. Tirpitz, as the founder of the High Seas Fleet, naturally had to determine the political needs of capital ships as absolute priority, and on the other hand, it was also due to the fact that the performance of early submarines was really difficult to meet the needs of the German Navy.

Naturally, Jochen did not want his submarine to be taken seriously by the Navy until 1904, as it was in history, so the performance requirements for submarines were quite high.

Hearing such high demands, Holland's passion as a designer was mobilized: "It was a very challenging request and an attractive idea, and I would very much like to be part of this program." He stretched out his hand

Seeing that Holland agreed, Hansen reached out with a smile on his face to shake Holland's hand: "I'm very glad to have you join, Mr. Holland." ”

"Oh, by the way, I haven't asked her name yet." Horan asked suddenly.

"Ub-0, Ub, an abbreviation for Untersee-boot, 0 means the origin, the beginning of a qiē."

"Great, when can I start my work."

"Anytime you feel like you can."

"Well, I hope it's now, right now." RS
