Speaking of this, Yang Zhen's fingers turned from Tongliao to Weng Niute Left Banner: "Lao Guo, what you said is not wrong, if it weren't for the fact that I approved Yang Jicai's guy to organize a cavalry mechanized cluster and insert it directly into the Weng Niute Left Banner, which relieved Umezu Mijiro's hand from a certain shape. It is highly likely that we will fall into passivity in both directions of Tongliao and Linxi at the same time. ”

"If Yang Jicai can achieve his goal, then for the safety of the two divisions in the frontal battlefield of Linxi, whether they want to or not, the Kwantung Army can only put this fifth division on the Linxi battlefield, but cannot be transferred to the Tongliao battlefield. In this way, we inadvertently dissolved, and among the three sharp swords hanging over the head of our army on the Tongliao battlefield, I am afraid that it is the most threatening one. ”

"And if the sea of fire tactics adopted by our army in Changling and Shuangshan can be as successful as the Alukorqin Banner, coupled with the Du Kaishan Division, which has been hiding behind Chen Hanzhang, the Japanese division that is inserted behind Chen Hanzhang will not be able to pose a threat."

"As long as Ma Chunsheng attacks quickly and strictly implements the battle plan of his superiors, he can also contain the Kwantung Army forces in Changtu and Lishu, southwest of Xinjing, and really threaten the flank of the enemy in Xinjing. In this way, the three threats of the Kwantung Army against our Tongliao battlefield will be completely resolved by us. ”

But whether this goal can be achieved, the most critical factor is whether Yang Jicai can return to his position and block the retreat of the two Japanese divisions in front of the Linxi battlefield. As long as he does it, this game of chess will really come alive, and all the problems will be solved. ”

After thinking about it, Yang Zhen pondered for a while and said, "Lao Guo, has not found the headquarters of the Seventh Division in Alukorqin Banner yet?" We provided them with the latest high-power monitoring radio, but we have not yet found the headquarters of the 7th Division, what are they doing? ”

"Before the main force of the 7th Division turned around last night, its division headquarters was in a state of advancement, and it was understandable that it could not be locked. However, when the main force of the 7th Division turned to the front line of Balaqirude and Ao Han Yingzi, and fought fiercely with our troops for most of the night, it was still impossible to determine the approximate location of the headquarters of the 7th Division. Are the results of their daily training and assessment of the three places all obtained by cheating? ”

Regarding Yang Zhen's dissatisfaction, Guo Bingxun shook his head and said: "No. 1, since the battle of the Alukorqin Banner started yesterday, our army's electronic jamming machine has been implementing full-band jamming for the power stations of more than 50 watts used by its wings and above. After a long period of electronic suppression, the 7th Division has hardly stopped using high-power radios since nightfall last night. ”

"During the day, the headquarters of the 7th Division was always on the move, and at night there was little use of high-power radios. It was quite difficult for them to lock down the location of the station in that little time on the phone. Moreover, this Seventh Division is very cunning, and when its high-power radio stations are rarely turned on to send and receive telegrams, they always adopt the method of feints from multiple radio stations in many places, and the time for turning on is extremely short. ”

"Although our army has spent a lot of energy, it has not been able to accurately locate the location of its radio station. No. 1, we are now equipped with only two radio direction finding devices, and the performance is still not perfect. Not to mention the poor accuracy, once there is a large number of radio signals, it is difficult to distinguish which signal is real and which is fake. ”

"In addition, during last night's night battle, when the high-power radio station was electronically suppressed by our army, the communication and liaison of the Seventh Division mainly used the field telephone line set up and the tactical radio relay report of less than 15 watts, and avoided the use of high-power radio stations as much as possible."

"Due to the limitations of the terrain and equipment, as well as the reasons why the Japanese army used various means to cover up their radio communications, our radio surveillance in the territory of Linxi was never able to capture the signal of the radio station of the regimental headquarters of the 7th Division. Therefore, this responsibility is all on their heads, and it is also incomplete and objective. ”

"However, the headquarters of the 7th Division can now be sure that it has been defeated by our army. Last night, in the night melee of Zagastenor, the attack of our army was scattered by the Japanese counter-charge. After this part of the troops was dispersed, the chief of staff of the regiment led them to the front line of Balaqirude, and on the way to the main force commanded by Yang Jicai, they encountered the headquarters of the 7th Division on the outskirts of Baichengzi. ”

"After a fierce battle, all the cadres and fighters of our army who participated in the battle were killed except for a few soldiers who were sent by the chief of staff of the regiment to report. The headquarters of the 7th Division, which was encountered with it, was also completely destroyed by our army. When our reinforcements received the news and rushed to reinforcements, they captured only the seriously wounded chief of staff of the Japanese 7th Division, Naoliang Fukuda, and a senior combat staff officer. ”

However, when the reinforcements were cleaning up the battlefield, they found the codebook of the Seventh Division's communication with the Sixth Army of the Kwantung Army and the Kwantung Army Headquarters on the body of Miao Zhihe, the chief of staff of the regiment who had been killed. The captured Japanese code book has now been sent to Wang Guangyu's headquarters. ”

Guo Bingxun's answer made Yang Zhen frown slightly, and then said with some uncertainty: "What was seized is a complete set of codebooks?" What about the Japanese army's radio station, has the Japanese army captured a complete new high-power radio station? The most important thing is whether the cipher machine used by the Japanese army has been captured? ”

"Didn't we have information that the Japanese army base camp imported a batch of T-shaped Engeny code cipher machines from Germany at the beginning of this year and distributed them to the divisions and regiments and above? How's it going, have they been seized this time? This thing is much better than the ninety-one cipher machine with the performance of the strip imitated by the devil. ”

Regarding Yang Zhen's extremely rare and uncertain rhetorical question, Guo Bingxun said with certainty: "We only seized the code book, as well as the entire strategic deployment posture and plan of the Japanese army for this operation. Several radio stations at the regimental headquarters of the 7th Division, with the exception of one that was damaged by a direct hit from a pistol, were blown up by a grenade that fell into the tent. ”

"As for the cipher machine, the reinforcements did not find it when they were cleaning the battlefield. However, No. 1, I think that the Japanese army's cipher machine equipment cannot achieve such a large density, and every division can be equipped with this kind of German-made cipher machine. According to my judgment, the troops at the division and regimental level of the Japanese army should still use ordinary radio ciphers to make up costs. ”

"I heard about this kind of cipher machine when I was studying in France, and its encryption performance is extremely good. Without obtaining the secret key, even if this kind of cipher machine is captured on the battlefield, it is difficult to decipher the other party's telegram. However, because of its functions, I am afraid that the level of configuration of this cipher machine will not be too low. In particular, division-level troops should not be distributed. ”

"As a divisional unit, the use of this new type of cipher machine on the battlefield is very easy to be captured by the enemy, which is not conducive to the secrecy of radio information. So I don't think the Seventh Division has used, or at least hasn't, used this cipher machine.

"And judging from the results of our monitoring, compared with the lower-level troops, the password change at the division and regiment level of the Japanese army is not very frequent, and the password is still relatively fixed. This also shows that the Japanese army, at least in this battle, did not put this kind of cipher machine into actual combat. ”

"If the Japanese army is really equipped with this kind of cipher machine, I think it should be a military-level unit as a strategic cluster. At the division and regiment level, I am afraid that this kind of cipher machine will not be distributed. At present, we do have intelligence that the Japanese army has imported a batch of such high-end cipher machines. ”

However, the production technology of this cipher machine is complex and the process requirements are high, and even the output in Germany, where he invented it, is not very large. Even if the Japanese army imported, the number was probably quite limited. According to my judgment, it is certain that the Japanese army imported this kind of cipher machine, but it should be mainly equipped with large ships with high security. ”

"The number of ground forces in the configuration should not be large. Even if it is deployed, it should be in a strategic group at or above the corps level, not in a tactical group at the division and regiment level. And I have a feeling that the Japanese army will never use this kind of cipher machine on the battlefield in China. ”

"Because from the bottom of their bones, they don't have the ability to decipher radio from us or Chongqing. On the contrary, it was the telegram from Chongqing, but they deciphered countless copies. Despite many failures at our hands, they have not changed their contempt for us when it comes to radio decipherment. They imported this batch of cipher machines in order to prepare for the next stage of war against the United States and Britain. ”

Guo Bingxun's explanation, Yang Zhen just smiled. Yang Zhen has been fascinated for a long time by the Engeni code cipher machine, which has been famous for a long time in the entire World War II. He did think a lot after receiving the Japanese army base camp to spend a lot of money to import a batch of this cipher machine from Germany.

If this kind of cipher machine can be seized, it will be of great convenience to the future work of encrypting one's own radio communication and deciphering Japanese ciphers. The role of radio decipherment in warfare is crucial. It can even be said that it is related to the direction of the entire battle situation.

Throughout World War II, the invisible battlefield of the struggle for electromagnetic control has always run through the entire war. Although there is no smoke of war on the battlefield, the fight on this invisible battlefield is no worse than the real battlefield fierceness.

The saying that the decisive victory is not limited to the battlefield can be said to be appropriate in this invisible battlefield. Unscrupulous means to decipher the opponent's communication code are almost equivalent to installing a pair of eyes in the heart of the enemy's army. And this method has become an invisible weapon of victory for both sides in this war.

However, for Yang Zhen, it is a good thing that it was captured, and it is not a big deal if it is not seized, it is nothing more than thinking of some other ways and taking a lot of effort. The Japanese army is indeed quite rigorous in the formation of codes, and the decipherment work is not an easy task. However, there are always more ways than difficulties, as long as we start to ponder and work hard in many aspects, there is still a way to solve the problem.

In order to minimize the losses as much as possible, in this national liberation war, it is of course important to decipher the radio codes of the Japanese army's communications. But if you put all your hopes on this, you will be bound by your hands and feet. If you do it well, it can affect the direction of a war, but it cannot determine the fate of a war.

Regardless of whether Guo Bingxun's judgment on the use of this Engeni code cipher machine by the Japanese army is correct or not, it is actually not a big deal for Yang Zhen. The right to control the electromagnetic system is important, but war has never been a way to solve it. A variety of means are the most secure solution.

Of course, if it is really as Guo Bingxun judged, the Engeni code cipher machine imported by the Japanese army is mainly equipped with the navy, then let the Americans bother with it. After all, the Pacific Ocean is their main battlefield, and as Chinese, it is better to settle their own affairs first. It's better to have it, and it doesn't matter if you don't.
