Regarding Guo Bingxun's evaluation of Li Huilan, Yang Zhen just smiled and said: "She majored in mathematics when she was in college, and she was a natural number wizard, and she has a talent for numbers that ordinary people can't match. No matter how complicated the mathematical formula, it is easy for her to come by. ”

"I transferred her from the New Fourth Army to borrow her talent for numbers and code-breaking. The shape of our here is much more sinister than that over there. When she was poached, the commander of the New Fourth Army was still quite reluctant. The Communications Department of the Military Commission, which has long named important people, has also fought a lot of verbal lawsuits, and has also spent a lot of money. ”

"Although the composition of the codebook used by the Kwantung Army is relatively complex, it is not without certain rules to follow. The scrambled encryption method is just a little more scrambled. No matter how much you change or change your password, it's just the same. As long as you have patience, you can always find a certain pattern. ”

"As long as we find out the rules, plus our original captured Japanese code as the basis, it is not impossible to decipher it. The Kwantung Army suffered a great defeat for two consecutive years, and we seized a lot of the codebooks used by it. And the Kwantung Army, I don't know what they think, it's too confident. Or for some other reason, I am always unwilling to completely change the military password. The speed of password updates is not very fast. ”

"The password upgrade only reformed the original encryption method, from the original shift encryption method to the random encryption method. As for the coding order, it's basically the same old thing. This undoubtedly also brings a lot of convenience to our deciphering work, and saves a lot of time. ”

"Isn't there such a saying, it is called "all changes are inseparable". As long as we grasp this, I think there will still be some progress. What's more, she still has some of the original code books we have seized before as a reference, and it also greatly reduces the workload of deciphering the Japanese army's secret telegrams. ”

"To put it bluntly, the little devil is still very stingy. They introduced the most advanced Enigma cipher machine from Germany, but they were reluctant to invest capital in a comprehensive imitation. Instead, it imitated a so-called 91-style cipher machine with a lot of different performance. If they use the Enigma cipher machine entirely, we won't be able to decipher it even if we receive their cipher without the key. ”

After giving a short answer to Guo Bingxun's evaluation of Li Huilan, perhaps because he didn't want others to pay more attention to Li Huilan, Yang Zhen didn't explain too much in this regard. However, Yang Zhen did not immediately answer him about the latest battle situation and Guo Bingxu's construction.

Instead, he frowned and stared at the latest form of the enemy that had been marked by the combat staff officer on the map, and said for a long time: "Is there any change in the Japanese army that is currently behind the Alu Korqin Banner?" Or rather, did they add new forces in that direction? ”

In response to Yang Zhen's rhetorical question, Guo Bingxun shook his head and said: "At present, no new enemy situation has been discovered in the Kailu, Naiman Banner, and Kulun Banner around the Alukorqin Banner. In the territory of the front and rear banners of the left flank of Horqin, some newly increased Japanese troops were found. But the totals don't add up much. ”

"This area is the focus of our aviation and radio monitoring, and no new high-power radio signals of the Japanese army have been found. Infiltrating past reconnaissance units and aviation reconnaissance, with the exception of a few separate infantry brigades, no new divisions of the Japanese army have yet been found. These separate infantry brigades also did not move forward, but stayed behind to protect the supply lines of the Japanese army. ”

"However, in the territory of the Naiman Banner, the Japanese army has newly deployed two tank squadrons and an armored vehicle squadron, as well as a new independent mortar brigade and several field artillery squadrons. In addition, in the territory of Kulen Banner, we found three Japanese automobile fleets the size of automobile squadrons. In addition, around the perimeter of the Japanese supply lines, a number of new anti-aircraft artillery units were discovered. ”

"The total annihilation of the Seventh Division was this morning. Coupled with the large-scale radio interference we carried out throughout the Ximan battlefield, the destruction of the 7th Division is not necessarily in the hands of the Japanese army at present. Even if some stragglers were able to withdraw from the battlefield, the Japanese army would not be able to master it so quickly. Therefore, no new, more stringent hostile situation has been found in this regard. ”

In order to ensure the progress of the Ximan Battle, the Intelligence Department and the Communications Department of the Military Region dispatched a group of elite soldiers and strong generals to closely monitor the radio signals of the Japanese troops on the Ximan battlefield. In addition to the Japanese military radio stations that have been exposed so far, no new high-power radio signals have been found. From this, it can be judged that the Japanese army has not increased its strength in the West Manchurian battlefield at present. ”

After listening to Guo Bingxun's report, Yang Zhen stood up and walked to the front of the map, stared at the map carefully for a long time, and said: "It seems that the focus of the Japanese army's defense at this stage, at least for now, is still in Xinjing." That is to say, at least for the time being, before the Kwantung Army's air attack on the Songhua River embankment was successful, they were still mainly defensive on the Xinjing battlefield. ”

"But for Ximan, the current posture of the Kwantung Army can still be easily judged to be an attack. You're right, it's very likely that the Kwantung Army hasn't been able to grasp the battle situation in the Alukorqin Banner. Therefore, on the West Manchurian battlefield, the Japanese army has not yet adjusted its troop deployment. But we can't hide this for too long. ”

"At this time, the Kwantung Army deployed the Fifth Division on the front line of Chaoyang and Xifuxin, what is the intention, at least we still don't know it yet. But I think that the deployment of the Fifth Division, such a veteran division of the Japanese army, and the one with the highest mechanized Cheng Dù at present, in this area is definitely not as simple as it seems on the surface. ”

"The retreat of the Chaoyang and Xifuxin lines here can ensure the safety of the Beining line, but the attack can enter the Rehe theater to the northwest. To the northeast, reinforcements to the Tongliao line. Its location is about equidistant from Linxi, Tongliao, and even the Changtu line, and even closer to the Tongliao battlefield. ”

"For the Kwantung Army, if the Fifth Division is placed in this position, no matter if there is a problem in any of these three directions, this Fifth Division can be quickly reinforced. If our army is not an advance army, it should not be the situation of the troops going south to the Bac Ninh Railway, but it can also ensure the safety of the Bac Ninh Line. ”

"Chaoyang and Xifuxin, and Changtu, Tongliao, and Chifeng all have railways to figure out. If needed, the Kwantung Army reinforcements will definitely not be too slow. Umezu Mijiro placed this fifth division here, which is almost equivalent to the position of the current general reserve of the Kwantung Army, which can be described as a seasoned soldier. ”

"Placing this Fifth Division here, it seems that it is defending, but it is actually an offensive position, which can be described as killing two birds with one stone. It can succeed in confusing us and making us think that the Kwantung Army is strengthening the defense of the Bac Ninh Railway. At any time, when we are a threat, a quick attack can be used to stab us in the waist. ”

"Not only the Fifth Division, which is deployed on the front line of Chaoyang and Xifuxin, but also the increase in the strength of the Kwantung Army on the front line of Lishu, Shuangshan, and Changtu should also attract our attention. I don't think the Kwantung Army's increase in troops in this direction was just for the sake of Shinkyo's left flank. ”

"These three places not only protect the left flank and rear of Xinjing, but also the right flank of the entire Tongliao battlefield. Changtu is only more than 300 kilometers away from Tongliao in a straight line. Even if you don't use the railway, if you concentrate a large number of cars, you can still get to the Tongliao battlefield in the shortest possible time. ”

"In the end, it is a top student of the Japanese Army University, is this Umezu Mijiro still very experienced in his vision of using soldiers? The troops deployed by the Kwantung Army on the front line of Ishu, Shuangshan, and Changtu are not too much, but they are just right up to our waists. It looks like it's heavy defense, but it's actually in the best position to attack. ”

"Not only when the battlefield in Xinjing is unfavorable, but Xinjing can be quickly reinforced. Once the Tongliao battlefield is needed, it can also launch a roundabout attack on the flank of our army on the Tongliao battlefield with all its might. It can be described as killing two birds with one stone, and pressure can be exerted in both directions at the same time, and both are in the place where our army must be saved. ”

"And this Fifth Division, on the surface, seems to want to strengthen the defensive posture of Beining Road, but in fact, this Fifth Division only needs to be on the front line of Chaoyang and Xifuxin, even if it does not make any moves. But as long as it is there, all the troops on our Linxi battlefield will be completely contained. ”

"Even if this Fifth Division cooperates with Changtu, Lishu, and the existing Japanese troops on the Tongliao battlefield to the north, it can form a flanking attack on our Tongliao combat troops. To the west, you can throw yourself into the Linxi battlefield at any time. Umezu Mijiro's two hands, are they very vicious? ”

"If I'm not mistaken, the next target of Umezu Mijiro's deployment is Chen Hanzhang's department in the Tongliao battlefield. No, it can even be said that it is not the next target, but the ultimate goal of his counterattack is Chen Hanzhang's department on the Tongliao battlefield. ”

"They used the Linxi Battlefield and the Xinjing Battlefield to drag down the main force of our army, and then went all out to deal with Chen Hanzhang. Strive to wipe out Chen Hanzhang's troops in one go. Completely divide our army into two separate parts, and then solve the rest of the forces that we have been divided into two large parts, unable to coordinate and support each other. ”

"What bombed the embankment of the Songhua River, and what concentrated three divisions to take the lead in counterattacking on the Linxi battlefield. They are all engaged in a thorough strategic deception, and their real intention is to divert our attention from the Tongliao battlefield. Even if he placed the Fifth Division in Chaoyang and Xifuxin, it is very likely that his real intention was not Linxi and Rehe, but Tongliao in the north. ”

"Of course, bombing the embankment of the Songhua River and cutting off the rear road of our army north of Xinjing with water instead of troops is also part of their entire plan. It is certainly possible to cut off the retreat of our army in the south of the Yangtze River, and use the flood to reduce the combat effectiveness of our army, so as to create a favorable fighter for our army on the battlefield north of Xinjing. Even if it didn't work out, it covered their truest strategic intentions on the entire battlefield. ”

Yang Zhen pointed to the locations of Chaoyang and Xifuxin on the map and said, "Lao Guo, look, if this Fifth Division is from the front line of Chaoyang and Xifuxin, it will ostensibly threaten the flank of the Linxi battlefield. But in fact, from the perspective of distance, they are a greater threat to the Kailu and Tongliao fronts. ”

"From Chaoyang, Xifuxin to Kailu, whether it is terrain or transportation, it is more conducive to the operation of large corps than the Linxi battlefield. The Fifth Division is the division with the highest level of mechanization in the Japanese army, and it is also one of the few four-unit divisions in the Japanese army at present. ”

"If this Fifth Division forcibly advances towards Kailu, and the Japanese troops at Changtu and Lishu penetrate directly into Bayantara, plus the Japanese troops who are currently attacking behind Chen Hanzhang, as well as the 14th Division of the Japanese Army in Tongliao and Kailu, Chen Hanzhang's headquarters will be in danger of being completely surrounded by the Kwantung Army."

"This Fifth Division, together with the Japanese troops in Changtu and Lishu, as well as a Japanese division that is currently advancing behind Chen Hanzhang from Changling and Huaide to Zhanyu and Kaikai, form three sharp swords that may fall on Chen Hanzhang's head at any time. Once the Kwantung Army thinks that the time has come, it will not hesitate to dispatch on all fronts. Cooperate with the 14th Division of the Japanese Army in Tongliao and Kailu to divide and encircle Chen Hanzhang's headquarters. ”
