Just when Chairman Chiang ordered Chen Cheng to prepare for a preemptive strike, Okamura Ningji's mood was also panicked, because he had originally planned to launch an attack in Nanchang and Suizao areas on 10 March, but because of ammunition and supply problems, he was forced to change the time of the attack to 20 March. It's just that the problem of insufficient ammunition is a big deal, and Okamura can't do anything even if he makes a fire.

After March 5th, Okamura had nothing to do for the time being, remembering that he had not fished for more than half a year, the spring in Wuhan had arrived, and the spring was deep, if he could catch a few catties of Wuchang fish for the soldiers to practice, what would he feel like?

With this in mind, Okamura decided to go fishing on the Yangtze River on March 10, Army Day, and in order not to return empty-handed, he also ordered Miyamoto Ichiro, a combat staff officer, to bring some grenades and prepare to blow up the fish when there was no harvest.

It's just that when Okamura was just about to set off, Chief of Staff Numata Taka ran over in a panic and handed him a telegram, and Okamura Ningji's face suddenly changed when he saw it, because this was a telegram sent by Chairman Chiang in the name of the Military Commission to the Fifth and Ninth War Zones half an hour ago. In the telegram, Chiang demanded that a preemptive battle plan be issued, requiring the troops to complete the preparatory attack within 10 days, launch a general offensive on the 15th, and actively cooperate with the Fifth Theater.

Okamura Ninji was shocked into a cold sweat when he saw this deciphered message, and hurriedly shouted.

Miyazaki ...... Miyazaki ....... ”

Kazuo Miyazaki, the director of the war room, hurriedly ran into the war room, and after reading the telegram in Okamura Ninji's hand, he said: "Your Excellency, commander, I think the time of the general attack should be advanced, and the 101st Division of Saito and the 107th Division of Hirakawa will be the main attack on Nanchang. The 6th and 116th Divisions attacked Jiugong Mountain, and the general attack time was four days ahead of schedule. Changed to 16 days"

Okamura touched his chin and said to the chief of staff of Numata on the side: "Nanchang must be occupied, the 101st Division failed to attack Nanchang half a year ago, and the 107th Division was newly established, do you think their combat strength can complete such a difficult task?" ”

Numata Taka said: "Your Excellency Commander, the art of war of the people of China also says: mourning soldiers will win." You don't have to worry about it. ”

Okamura is still silent, he is a cautious general, the enemy's combat orders are very targeted, and he can't be unguarded, and the risk of attacking from both sides at the same time is already greater, but now it is much greater. He paced back and forth a few times before he said, "The 3rd, 13th, and 16th divisions will only be on guard against the enemy with Suizao, and will attack after the southern front is clear, and before that." The Northern Front Group should be used as a campaign agitation corps. Was it too late to attack on the 16th? ”

Miyazaki replied: "Staff Officer Miyamoto has made a careful plan, and the Southern Front Corps will all enter a state of attack as early as the 15th. Xue Yue's department is in training, and his mobility is extremely poor, and Chairman Jiang is probably more than capable of doing so. ”

Okamura nodded slightly, a sneer appeared at the corner of his mouth, and the muscles on his face tensed: "One day later, on the 17th, Foxiao will attack in three ways, and the 116th Division and other divisions will all attack Wucheng from Fanyang Hubei." The 6th Division attacked Wuning. The 101st and 107th Divisions of the Central Road crossed Xiushui to attack Nanchang, and the 3rd, 13th, and 16th Divisions each sent a wing to make a feint to Suizao. to cover the true intentions of the army. ”

With Okamura Ninji's order, the Japanese 11th Army suddenly began to move, and because the Japanese army was well-equipped, it also won time, and on March 15, most of Xue Yue's troops had not yet completed the assembly. The order to attack became a dead letter.

On the morning of 17 March, Chairman Chiang raised his head to the sky and sighed after receiving a telegram from the Japanese army to attack Nanchang at the Xiushui River: "Will the sky kill me?" "He knew very well that some of the troops that were being assembled had not yet been rebuilt, and if they were to attack by force. The casualties would be much greater than if he had not done this kind of battle build-up, and at this point, he had to hope for a miracle.

"What...... The Japanese army suddenly launched a full-scale attack on Nanchang, just before we were ready to attack? ”

In the Ninth Theater Headquarters in Changsha City, Su Jin's complexion, who hurried to the headquarters, also changed, and he had just received the order from the Ninth Theater to prepare to reinforce Nanchang, but within a few days of the order, he heard the bad news, and the Japanese actually attacked in advance.

"Yes!" Wu Yizhi, the chief of staff on the side, also changed his previous calmness, and said with a dark face: "Originally, we planned to take the initiative to attack the Japanese next month, but somehow the Japanese army suddenly moved ahead of schedule not long after the order was issued, which completely broke our plan, and now it is all chaotic!" ”

Su Jin's face also became ugly, and after thinking for a while, he said with a sinking face: "I think I probably know what's going on, if what I expected is right, it's definitely because our telegram leaked!" ”

Wu Yizhi was stunned for a moment, and then blurted out: "What...... The password is leaked, it can't be, our password changes every once in a while, how can the Japanese decipher our password? ”

"Nothing in this world is impossible." Su Jin shook his head, he immediately recalled the previous reports in later generations, in the final analysis, behind the code breaking is a contest of mathematical ability, and the level of mathematics in China during the Republic of China was very low, at that time, the Japanese did everything to deal with China, for which the Japanese specially set up an intelligence department specializing in code breaking in the Forbidden City in Beijing, which has been stationed hundreds of code experts for a long time, specializing in deciphering the code of the Chinese army,

Beginning in June 1938, the Japanese army began to continuously decipher the army codes of the Nationalist army, and by the beginning of 39, almost 80 percent of the codes of the Nationalist army could be deciphered by the Japanese army.

Thinking of this, Su Jin solemnly said to Xue Yue: "Chief Xue, please send a telegram to Chongqing immediately, just say that the code we used has been deciphered by the Japanese army, if we don't want this situation to happen again, our army must replace the code book on a large scale, or come up with better means to prevent decipherment." We will have to replace all the codebooks now, but I guess this is only a stopgap measure, and the Japanese should be able to decipher it soon. ”

"It's not a trivial matter to change all the passwords, it's impossible in a few days, but if that's the case, how can we fight?" Xue Yue couldn't help but scolded irritably.

Su Jin can understand Xue Yue's troubles, the leakage of the password is not a trivial matter, this is equivalent to all the combat orders issued by him are clearly displayed in front of the eyes of the Japanese, if it is really like this, how can it be fought? It's like everyone playing mahjong together, on the one hand, the cards are tightly closed so that no one can see them, and on the other hand, all the cards are placed on the table to play with others, so that you are the god of gambling and have to lose the bottom of the world.

After thinking for a while, Su Jin suddenly thought of something, his eyes suddenly lit up, and he slapped the table: "Sir, I have a way." ”

Xue Yue, who was anxious, didn't raise his eyelids and said, "Oh...... What can you do, could it be that in addition to knowing how to fight, you are also proficient in telegraph ciphers? ”

Okay, for the sake of you just becoming my daughter-in-law's main marriage, Su Jin took a deep breath and said: "Chief Xue, Chief Wu, to be honest, my country's overall mathematical level is not as good as Japan, so it is not surprising that our telegram was deciphered by the Japanese, but we can use one thing, which can greatly improve the overall level of confidentiality of our telegram, so that the Japanese will not be able to decipher our telegram in the short term." ”

"What can you do?" Xue Yue looked at Su Jin suspiciously, he still didn't believe that Su Jin had that ability.

Su Jin smiled mysteriously: "Chief Xue, I don't know if you have heard of the German Enigma cipher machine. ”

"Enigma cipher machine?"

As soon as they heard this, the faces of Xue Yue, Wu Yizhi, Wu Qiwei and others immediately changed. As a well-known cipher machine, the Enigma cipher machine has now become the standard cipher machine of the German Wehrmacht, how could they not know it.

"You have this cipher machine?" Xue Yue's face changed slightly.

"Yes!" Su Jin admitted it very calmly.

"Can you get a machine like this?"

"Yes!"

As soon as they heard this, everyone was surprised, this kind of cipher machine invented by the Germans is Germany's top secret, and the Germans are not even allowed to leave a machine outside, how can Su Jin get his hands on it? Could it be that his relationship with the German government has reached such a close point? For a while, everyone's gaze at Su Jin was a little different.

"You don't care how I got it, you just need to know that I can get this cipher machine." Su Jin said very simply.

Su Jin knew very well that although many people in later generations said that the Enigma cipher machine was rubbish, saying that the allies had deciphered this cipher machine long before the war, Su Jin laughed when he heard it. If this kind of tatter had been created according to the rigid and serious character of the Germans, Germany would have been destroyed many times, and the real situation is that although the commercial version of the Enigma cipher machine had long been deciphered by several Polish scientists, the military version, especially the Navy's military version, had never been deciphered until 1941 when the British Navy captured the German submarine U-110 on the warship Captain Joe Baker-Cresswell's Bulldog. It was only then that the Allies were afraid that the Germans would notice the replacement of the codebook and the cipher machine, so they worked hard to create an illusion, so they concealed the truth of the matter.

And now Su Jin provided to the national army is the army version used by the German Wehrmacht, although the secrecy of the army version is not as high as the navy version, but for the current Japanese, it is difficult to decipher this cipher machine. (To be continued.) )
