When Cheng Hao handed the Chinese copy to Lu Teyansi, he looked at Lu Teyansi's surprised eyes and quipped, "Your Excellency, commander, why are you a little surprised?" ”

Lu Teyans did not refute, carefully rolled the brows in his hand, and said with a wry smile, "I really didn't expect that you really asked, but can you guarantee the accuracy of the information?" Even if they tell a lie, we will be in more danger......"

"At present, Bismarck has sunk the Hood, Churchill will definitely not give up, although there are a large number of merchant ships in the Atlantic, but there are also a large number of escort fleets, it is estimated that they have begun to encircle and suppress us from all sides, such a big move, presumably our intelligence department will soon have news, and it will be good to compare it then?"

In this regard, Cheng Hao has long had a plan, and it is estimated that Berlin will be able to react soon......

Lütjans looked at Cheng Hao thoughtfully and continued, "Just like you said, the Bismarck has now sunk the world's largest and most powerful battleship cruiser, the Hood, and has become a dreadnought that has attracted worldwide attention. Even if the Bismarck were parked in the dock, it would be able to contain a large number of British ships and pose a serious threat to the Allied convoys......"

This is the existence of the fleet! It refers to a naval fleet that exerts some influence over a certain area of the sea, but never leaves its main port.

Once out of port, the fleet is likely to be wiped out in naval battles and can no longer influence the enemy's decision-making. But if it stays in the harbor, the enemy will have to deploy military forces or even change strategic decisions in order to defend against it.

The existential fleet doctrine is usually used by the inferior side in the struggle for sea supremacy, as a means of weakening the enemy's control over a particular sea area, rather than actively seizing sea supremacy.

The battleship Tirpitz in the previous life is a typical fleet of existence, as a representative of the cannon of the giant ship, the fate of the Tirpitz is also very similar to that of other battleships, in its limited life, the use of large-caliber main guns is very small.

However, the ship's long-term dormancy in Norwegian waters has contained a large number of British naval and air forces, making it difficult for Britain to sleep. Its presence was much more useful than sinking one or two British capital ships.

The Tirpitz can be said to have taken the theory of the existence of a fleet to the extreme, but for this kind of fleet cowering in the harbor, Cheng Hao can be said to be the extreme, in his opinion, the truth is only within the range of cannons!

After thinking for a moment, Lu Teyans looked at the rough sea and said to himself, "It seems that you have indeed grown a lot, and the Führer's hard work has not been in vain......

"Hey......" Cheng Hao, who had only obtained part of the memory of his predecessor, didn't know what Lu Teyansi meant at this moment, so he could only deal with it: "In addition, I have asked Hood to record their codebook, no matter what tactics we use next, at least we can strike first." ”

"Really...... It's a great job, so what conditions did you put forward to impress them? Lu Teyansi is worthy of being a veteran, and he can see Cheng Hao's thoughts at a glance.

Cheng Hao coughed dryly and said, "With their current situation...... I'm afraid the most tempting thing for them is to ensure the safety of their lives......"

"Life safety?" Lu Teyansi glanced at Cheng Hao and smiled, "It seems that they are still too nervous, but Hood used to be a ship spirit, which is of great help to us to understand the combat methods of the British martial spirit, this is the first time that the enemy martial spirit has been captured on a frontal battlefield, how can it be easily exchanged?" ”

"As for what you said about the round-up of the British fleet, I will report it to Berlin, no matter what kind of combat method we take, there must be a commander with rich combat experience on the Tirpitz, given our current situation, only you can meet this situation, and the Tirpitz is a sister ship of the Bismarck, and it is much easier for you to command than other ships, do you have any objections now?"

Cheng Hao hurriedly waved his hand, asking the Tirbitz to also participate in this operation, which was originally proposed by Cheng Hao himself, and now it seems that there is no one else to serve except himself, and there is Sebastian, presumably there is no big problem in commanding.

As for the Bismarck, there is a veteran Lütjans who has been in a hundred battles in charge, so naturally there is no problem, so Cheng Hao hurriedly expressed his attitude to Lütjans, "After Bismarck is done, she and I will immediately go to the battleship Tirpitz to complete the handover work." ”

"The ship... Captain, the codebook has been written down......" Bismarck, who still had a hint of blush in his ears, stammered and reported to Cheng Hao.

Cheng Hao, who was in front of Lu Teyans, couldn't make any other moves, Cheng Hao, who took the code book casually, nodded at Bismarck, and smiled, "Trouble Bismarck......

Hurriedly handed the codebook in his hand to Lu Teyans, you must know that on the battlefield, the figure of passwords is not uncommon, and cryptography has a natural connection with war.

Passwords can be said to have a crucial impact on the outcome of a war! Historically, there have been numerous examples of "encryption" and successful "decipherment" of operational intelligence, which have brought about a major reversal of the war situation......

In Cheng Hao's original world, the British intelligence agencies intercepted and deciphered the long telegram sent by Lütjans to the Führer for more than half an hour. As a result, Bismarck, known as the most powerful giant battleship in the world at that time, the pride of the German Navy, was killed in the belly of the fish on its first voyage!

There are too many cases in this way, in addition to the comparison of the strength of the two warring sides, intelligence is also the most important part of the battlefield, the first to understand the layout of the other side, according to which you can change your own battle plan, the first to occupy the favorable terrain, but the other side has no knowledge, stepping into the encirclement, think about what a terrible thing it is......

Looking at the codebook in his hand, Cheng Hao breathed a sigh of relief, although he has only been here for a few days, but history has gradually begun to deviate from the original track, compared to the original German fleet, now it is undoubtedly much stronger, whether it is the destruction of the Hood and the Prince of Wales, or the arrival of the Altmark and the addition of the Tirbitz and the U-boats, Cheng Hao has a little more confidence in this operation.

"If the authenticity, reliability, and timeliness of the codebook are not confirmed, this template can only be used as a reference, but your mission has been completed very well, and you and Bismarck are ready to board the ship next."
