While Tan Renhao and his family were nervously preparing for war, Prime Minister Xue Xiyue left the imperial capital on November 4 and flew to Tehran, the capital of the Persian Empire. On the same day, the Chancellor of the German Empire also left Berlin and headed for Tehran. The Big Three summit was officially convened on November 5.

The Tehran meeting was the first summit of the "Big Three" after the outbreak of war, and it laid the foundation for future summits. The meeting attracted the attention of all countries, and reporters from more than 10 countries who made a special trip to Tehran covered the whole meeting. Thanks to the help of modern communication equipment such as telegraph and broadcasting, Tan Renhao and his team were also able to keep abreast of the progress of the meeting thousands of miles away. They did not learn about the progress of the meeting through newspapers and other media, the Imperial Admiralty would receive the minutes of the meeting sent by the Imperial Ministry of Foreign Affairs every day, and Tan Renhao could see these records and learn about the progress of the meeting as soon as possible.

In the first three days of the meeting, the heads of state of the three countries first held three bilateral talks, the main purpose of which was to determine the mutual assistance plan for 24 years, and to inform each other of their war preparations, new battle plans, domestic situation, and other information that needs to be understood by each other. The formal summit of the three countries was held on the afternoon of 8 November, and several major topics were first decided. That night, Xue Xiyue went to meet the Persian Emperor.

The most important talks took place on the morning of the 9th. Prior to this, the diplomats brought by the heads of state of the three countries had already held detailed discussions on the fundamental war strategy of the alliance bloc. The negotiations were mainly between the diplomats of the three countries, and the main content of the negotiations was to define the basic war strategy of the alliance and to define a guiding program document that would lead the "Allied bloc" (as it was later called) to ultimate victory.

On the morning of the 9th, the heads of state of the three countries finalized the most important matters of this programmatic document (in fact, the signing of this document will not wait until the next summit, and after that, the diplomats of the three countries have been negotiating for several months to determine the details, even every word). The most important of these, and ultimately the fate of the defeated powers, is that no member of the Allied bloc will enter into separate armistice negotiations with any of the hostile countries; The non-acceptance of the conditional surrender of the hostile countries (this was established at the Second Summit, which was not announced at the time, but was only written into the Tehran Declaration) was only a single sentence, but it was this sentence that brought together the main members of the three Allied Blocs, as well as all the other member states (the Kingdom of Korea, the Kingdom of Thailand, and the Kingdom of Ceylon at that time). Greece, Finland and more than a dozen other countries joined the Allied bloc and signed the Tehran Declaration before the end of the war, the Allied bloc member states increased to more than forty) tied to the same chariot. After the signing of the Tehran Declaration, no country within the Allied bloc could accept the surrender of a hostile country alone, and it was not possible to negotiate surrender with a hostile country.

In addition to this declaration, the three heads of state also decided to establish a joint command. The command, which is based in Tehran, is not responsible for specific war command. Its primary responsibility is to inform other countries of the campaign and strategic plans. It also requires relevant countries to take cooperative actions to maximize the efficiency of warfare and strike at the enemy. Complete the battle plan. Subsequently, the responsibilities of this joint command will be further expanded, and in addition to undertaking liaison work, it will also undertake the formulation of part of the campaign plan, especially the formulation of multinational joint campaign operations. For example, the Tang Empire's strategic bombing of Russia later obtained the help of the German Empire and the Persian Empire through this command.

On the basis of the Joint Command, the three countries have also established a joint war-related multinational department, such as the Joint Intelligence Center (mainly responsible for the exchange, sharing, and mutual transparency of information), the Foreign Affairs Center (for resolving diplomatic disputes within the Allied Powers and dealing with diplomatic cooperation during the war), and the Joint Logistics Command (mainly responsible for mutual support of war materials, mutual transfer of military technology and industrial technology, and logistics support for cross-border operations of the armed forces).

On the 10th, the heads of state of the three countries, as well as the heads of other Allied member states who arrived one after another, and the representatives of the heads of state jointly issued the "Tehran Declaration," which is a declaration of war with a clear target, and a declaration of war by the Allied bloc against all hostile countries. It was also a manifesto that guided the Allies towards victory. This manifesto was broadcast all over the world, not only by the people of the Allied bloc, but also by the civilians of all the countries of the "anti-Tang Alliance." It's not just a manifesto, it's a battle cry!

Prior to this, the Tang Empire and other countries were fighting their own wars, facing different enemies and waging different wars. After that, these countries with common interests came together and formed a powerful fighting force. They have a common goal, a common enemy, and a common interest. From the moment the declaration was issued, the Allies were no longer alone in more than a dozen countries, but as a whole, hand in hand for the final victory!

In this sense, the Tehran Declaration is no less important than a few new weapons, a large fleet, or a powerful ground army. The manifesto itself may not be lethal, but it heralds the dawn of a new era. In war, there is no difference between allies, there is no mutual suspicion, in order to survive, for victory, all countries are united, united in front of a common goal, and will go all out for this common goal.

Comparatively speaking, the significance of the meeting of the heads of the seven countries of the "Tang Alliance" is too small. At the time of the G-7 meeting, no programmatic document was proposed, no guiding war policy was provided for the alliance, no common goal was set, and no institutions were established to work together.

In addition to the declaration, the collaborative command and communication structures identified during the Tehran Conference may have had a greater impact on the war. The declaration is just a statement, it only shows the attitude of the allies, and in simple words, this is "words", and in order to implement "words", then actions are needed. The establishment of these coordinated command and communication institutions is "action", when "words and deeds" are "consistent" and "deeds" are put into practice, the power of "words" will be brought into play, and the effect of "deeds" will soon be revealed.

The manifesto itself was an encouraging piece of news, and the Empire's propaganda apparatus would never let go of such good propaganda material. Prime Minister Xue Xiyue returned to the imperial capital on the 11th. It was immediately announced through the public media that all negotiators in Washington would be withdrawn, and that all personnel of the imperial diplomatic mission in the United States would be withdrawn from the United States by the end of the month. Although the prime minister did not announce the severance of diplomatic relations with the United States, he sent a very clear signal. Now, even if the United States does not take the initiative to enter the war, the Tang Empire will declare war on the United States at an appropriate time.

"In addition to these, Prime Minister Xue Xiyue also provided support to the German Prime Minister at the Tehran meeting."

Nie Renfeng has been following the situation of the Tehran meeting, and he can also get the relevant meeting minutes in time. "We will no longer ask Germany to stop unrestricted submarine warfare. And it is also preparing for the resumption of unrestricted submarine warfare in the North Pacific by the end of this month. Germany welcomed this decision and will provide us with the latest submarine construction drawings to help us build large ocean-going submarines. What we need, though, is a better submarine, and the help of German submarine engineers, not a couple of design drawings! ”

Gan Yongxing and Tan Renhao both laughed.

"Now there is only one question, and that is who will ignite this war."

Nie Renfeng brought over two cups of coffee, "What the Prime Minister means." We will base our meeting on the United States against Tehran. And then what kind of reaction will be if we withdraw negotiators, what kind of reaction will be if we withdraw diplomats. ”

"What does that mean?"

Tan Renhao looked at Nie Renfeng a little puzzled.

Gan Yongxing didn't understand either, and he also waited for Nie Renfeng to explain.

"We withdrew the negotiators. The evacuation of diplomats is actually a test of the details of the United States. ”

Nie Renfeng laughed, "Let's put it this way, if the United States reacts very violently, then the United States is not ready for war, and hopes to delay the time to enter the war a little longer." In this way, we will certainly take the initiative to attack and seize the initiative in the Pacific theater while the United States is not fully prepared. ”

"Then if the United States does not react, it means that the United States is ready for war, and we must be more cautious about the next war?"

Gan Yongxing said the second half of the sentence.

"Exactly."

Nie Renfeng crossed his hands. "This is the stone we used to ask for directions. Now that the stone has been thrown, it depends on the reflection of the United States. There will be news in the next few days. Of course, we are running out of time to prepare. ”

"Then we must bring the fleet to combat readiness as soon as possible."

Tan Renhao's expression became serious, "If the United States is stimulated, they may return to the war in advance!" ”

"That's what worries me the most."

Nie Renfeng nodded, "Judging from Japan's intelligence, the United States should not enter the war until December, and this happens to be completely consistent with the information we have obtained. The US military deployment in the Pacific is not yet complete. In particular, the military deployment in Australia will take at least a month. But we cannot rule out the possibility that the United States will start war in advance when it realizes that war is imminent and that we are likely to take the initiative to attack. ”

"In that case, we'd better move the fleet back a little bit now."

Gan Yongxing's expression also sank, "Moreover, we must send submarines to strengthen the cordon in the Mariana Islands, Hawaiian Islands, Caroline Islands and Australia directions, and grasp the whereabouts of the American fleet, otherwise, we are very likely to be attacked suddenly." Now, no matter which fleet is lost, or which fleet is heavily damaged, it will lead to us being beaten passively in the first half of next year! ”

"If the position of the fleet is too far back, it will not serve the purpose of covering the flanks."

Tan Renhao did not fully agree with the chief of staff, "Moreover, this will lead us to a passive situation in the early stage of the war, waiting for the American fleet to attack, which is not a good idea." ”

"Ren Hao's point of view is not wrong, we are not sure of the attitude of the United States at this time, and if the fleet is withdrawn, it will expose our intentions."

Nie Renfeng glanced at the two students, "Don't change the patrol sea area of the fleet for the time being, and at the same time let them strengthen their vigilance, enter the highest state of combat readiness, and be ready to engage the enemy at any time." Until the U.S. position is clear, we will make adjustments. ”

"Well, I'll contact the three fleets at once."

Gan Yongxing immediately stood up, which was actually putting the fleet in a dangerous situation in order to achieve political goals. Again, at the expense of military interests for political gains.

"Chief of Staff, let's go together!"

Tan Renhao followed and stood up.

"No, let Yongxing be responsible."

Nie Renfeng nodded at Tan Renhao and motioned for Tan Renhao to stay alone.

"Headmaster, I'll come back and report later."

After Gan Yongxing glanced at Tan Renhao, he immediately left Nie Renfeng's office.

Tan Renhao felt a little uncomfortable, after working in the Navy Staff these days, he found a serious problem. He's in an awkward position here. Nie Renfeng actually used Tan Renhao as the deputy chief of staff of the Navy, and in many cases, Tan Renhao's opinion was above Gan Yongxing, and his performance was not inferior to Gan Yongxing, which can be seen from the fact that Nie Renfeng took Tan Renhao to the capital instead of taking Gan Yongxing to the capital, and reused Tan Renhao after returning. Obviously, this is not a good thing. No matter how to say it, Gan Yongxing is the chief of staff of the Navy, and he is also very important to Tan Renhao, and now Tan Renhao occupies the magpie's nest, even if Gan Yongxing does not show any disgust, it will make the two unhappy. This will inevitably have a very bad impact on Tan Renhao's future development.

"People are old and useless!"

Nie Renfeng walked to Tan Renhao's side with a smile, "Don't worry about the chief of staff." I know Gan Yongxing very well, back then, when I took him, I was afraid you were still wearing open crotch pants. Maybe he is not the best admiral, but I believe that Gan Yongxing is the most cheerful admiral, otherwise, I would not have chosen him as chief of staff! ”

Tan Renhao laughed embarrassedly, he felt as if he was naked in front of the principal, and what he was thinking in his heart, the principal could see it at a glance.
