Regarding Guo Bingxun's evaluation of Li Huilan, Yang Zhen just smiled and said: "She majored in mathematics when she was in college. She is a natural numerical wizard and has a talent for numbers that is difficult for ordinary people to match. No matter how complicated mathematics is,
The formulas are all at her fingertips."
"I traveled thousands of miles to transfer her here from the New Fourth Army just to take advantage of her talent in numbers and code deciphering. The situation here is much more dangerous than that over there. When I recruited her, the person from the New Fourth Army
The military commander is still quite reluctant. We also had a lot of lawsuits with the Communications Department of the Military Commission, which had long named important people, and spent a lot of money."
"Although the codebook currently used by the Kwantung Army is relatively complex, it does not have certain rules to follow. The random bit encryption method just requires more scrambling. No matter how much the code is changed, it changes again.
, in fact, it is just the same thing. As long as you have patience, you can always figure out certain patterns."
"As long as we find out the rules and use the Japanese army's ciphers that we captured as a basis, it is not impossible to decipher them. The Kwantung Army suffered a major defeat for two consecutive years, and we seized a lot of code books used by the Kwantung Army. And the Kwantung Army
I don’t know what they think. They are too confident. Or for some other reason, they are always unwilling to completely change the military password. The password update speed is not very fast."
"The upgrade of the password only reformed the original encryption method, from the original shift encryption method to the random encryption method. As for the encoding sequence, it is basically the same as before. This undoubtedly also makes our deciphering work more difficult.
It brings a lot of convenience and saves a lot of time.”
"Isn't there such a saying? It's called everything that changes remains true to its origin. As long as we grasp this, I think we can still make some progress. What's more, she also has some of the original code books we captured before that can be used as a reference, which will also be a big help.
It reduced the workload of deciphering Japanese military secret messages."
"To put it bluntly, the little devils are still very stingy. They introduced Germany's most advanced Enigma cipher machine, but they did not hesitate to invest in a comprehensive imitation of it. Instead, they imitated a so-called 91-type cipher with a much different performance.
machine. If they all use Enigma cipher machines, even if we receive their cipher messages without the key, we may not be able to decipher them."
After briefly answering Guo Bingxun's evaluation of Li Huilan, Yang Zhen did not explain much in this regard, perhaps because he did not want others to pay more attention to Li Huilan. However, Yang Zhen did not explain much about the latest battle situation and Guo Bingxu's suggestions.
Didn't answer him immediately.
Instead, he frowned and stared at the latest situation between the enemy and ourselves that had been marked by the combat staff on the map. After a long time, he said: "The Japanese troops currently behind the Aruhorqin Banner have made any changes. In other words, have they added new troops in that direction?"
strength?"
In response to Yang Zhen's rhetorical question, Guo Bingxun shook his head and said: "Currently, no new enemy situations have been found in the Kailu, Naiman, and Kulun Banners surrounding the Aru Horqin Banner. However, they have been discovered in the Horqin Left Front Banner and the Back Banner.
Some newly added Japanese troops, but the total does not add up to much."
"This area is an area that we focus on aviation and radio surveillance. No new Japanese high-power radio signals have been found so far. The reconnaissance troops and aviation reconnaissance that penetrated the past have not found any new Japanese divisions except for a few independent infantry brigades.
The regiment appeared. These independent infantry brigades did not move forward, but stayed behind to protect the Japanese supply lines."
"However, in 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, we found three car squadrons in the Kulun Banner.
Japanese automobile convoys. In addition, some new anti-aircraft artillery units were discovered near the Japanese supply lines."
"The entire 7th Division was destroyed this morning. In addition, we implemented large-scale radio interference on the entire Western Manchuria battlefield. The Japanese army may not be able to control the 7th Division's destruction at present. Even if there are some scattered
The soldiers can withdraw from the battlefield, but the Japanese army cannot grasp it so quickly. Therefore, no new and more serious enemy situation has been discovered in this aspect."
"In order to ensure the progress of the Western Manchuria battle, the Military Region Intelligence Department and the Communications Department deployed a group of elite soldiers and generals to closely monitor the Japanese radio signals on the Western Manchurian battlefield. In addition to the Japanese military radio stations that have been exposed so far,
No new high-power radio signals have been found yet. From this, it can be judged that the Japanese army has not increased its troop strength on the battlefield in Western Manchuria."
After listening to Guo Bingxun's report, Yang Zhen stood up and walked to the map, stared at it 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. In other words, at least for now, it is in Xinjing."
Before the Kwantung Army succeeded in their air attack on the Songhua River Embankment, they still focused on defense on the Xinjing battlefield."
"But for Western Manchuria, the current posture of the Kwantung Army can still be easily judged as an attack. You are right, the situation of the Aruhorqin Banner battle is very likely that the Kwantung Army has not yet grasped it. So on the battlefield of Western Manchuria
, the Japanese army has not yet adjusted its troop deployment. But we cannot hide this matter for too long."
"At this time, the Kwantung Army deployed the Fifth Division on the new front line of Chaoyang and Xifu. At least we still don't know what the intention is. But I think the Fifth Division, such a veteran division of the Japanese army, is also
The deployment of the most mechanized division in this area is definitely not as simple as it seems on the surface."
"Retreating from the Chaoyang and Xifuxin lines here can ensure the safety of the Beining line, but the attack can go northwest into the Jehol theater. To the northeast, reinforce the Tongliao line. Its location is about equidistant from Linxi, Tongliao, and even the Changtu line.
Even closer to the Tongliao battlefield."
"For the Kwantung Army, by placing the Fifth Division in this position, no matter if there is a problem in any of the three directions, this Fifth Division can quickly provide reinforcements. If our army should not be the advancing army,
With the railway going south to Bac Ninh, the safety of the Bac Ninh line can be ensured."
"Chaoyang is connected to Xifuxin, Changtu, Tongliao, and Chifeng by railway. If necessary, the Kwantung Army's reinforcements will never be too slow. Umezu Yoshijiro placed the fifth division here, which is almost equivalent to the current
The Kwantung Army's general reserve position can be said to be experienced in military use."
"Placing the Fifth Division here, in a position that appears to be defensive but actually offensive, can be said to kill two birds with one stone. It can successfully confuse us and make us think that the Kwantung Army wants to strengthen the defense of the Beining Railway. It also
At any time when we pose a threat, they can quickly attack us and stab us hard in the waist."
"Not only the Fifth Division deployed on the Chaoyang and Xifuxin front lines, but also the Kwantung Army's increased troop strength on the Lishu, Shuangshan, and Changtu front lines should also attract our attention. I feel that the Kwantung Army's increased troop strength in this direction
It’s not just for the left wing of Xinjing.”
"These three places not only protect the left wing and rear of Xingjing, but also the right wing of the entire Tongliao battlefield. The straight-line distance between Changtu and Tongliao is only more than 300 kilometers. Even if you don't use the railway, if you gather a large number of cars, you can still get there
Arrive at the Tongliao battlefield in the shortest possible time."
"After all, he is a top student at the Japanese Army University. Umezu Yoshijiro still has a sophisticated vision for military use. The Kwantung Army's troops deployed on the front lines of Lishu, Shuangshan, and Changtu are not too many, but they are right up to our waist.
.It may appear to be focused on defense, but it is actually in the best attack position.”
"Not only when the Xinjing battlefield is unfavorable, we can quickly reinforce Xinjing. Once the Tongliao battlefield requires it, we can also launch an all-out roundabout attack on the flanks of our army on the Tongliao battlefield. It can be said to kill two birds with one stone. It can put pressure on two directions at the same time, and both
In the place where our army must rescue."
"On the surface, the fifth division seems to be strengthening the defensive posture of Beining Road. In fact, as long as the fifth division is on the front line of Chaoyang and Xifuxin, even if it does not carry out any actions, as long as it is there, it will
All our forces on the battlefield in Linxi are completely contained."
"Even if the fifth division goes north and cooperates with Changtu, Lishu, and the existing Japanese troops on the Tongliao battlefield, it can form a pincer attack on our Tongliao combat troops. To the west, it can be thrown into the Linxi battlefield at any time. Umezu Yoshijiro's two skills
, is it very vicious?"
"If my judgment is correct, the next target of Umezu Yoshijiro's deployment is Chen Hanzhang's troops on the Tongliao battlefield. No, it can even be said that it is not the next target, but the ultimate goal of his counterattack is the Tongliao battlefield.
The subordinate of Chen Hanzhang."
"They used the Linxi battlefield and the Xinjing battlefield to hold back the main force of our army, and then went all out to deal with Chen Hanzhang. They tried to annihilate all Chen Hanzhang's troops in one go. They completely divided our army into two disconnected chunks.
Then we will deal with the rest of the troops one by one, which we have been divided into two large pieces and cannot coordinate and support each other."
"The bombing of the Songhua River embankment and the concentration of three divisions to take the lead in counterattacking on the Linxi battlefield are all a complete strategic deception by them. Their true intention is to divert our attention from the Tongliao battlefield.
Come. Even if he places the Fifth Division in Chaoyang and Fuxin in the west, his real intention is most likely not Linxi and Rehe, but Tongliao in the north."
"Of course, bombing the Songhua River embankment and using water instead of troops to cut off our army's retreat north of Xinjing is also part of their overall plan. If it is done, of course, it can cut off our army's retreat in the south of the Yangtze River and use floods to reduce our army's combat effectiveness.
Solving the battlefield north of Xinjing created a favorable opportunity for our army. Even if it did not succeed, it also covered their true strategic intention on the entire battlefield."
Yang Zhen pointed to the positions of Chaoyang and Xifuxin on the map and said: "Look, Lao Guo, if the fifth division starts from Chaoyang and Xifuxin, it will appear to threaten the flanks of the Linxi battlefield. But in fact
Judging from the distance, they pose a greater threat to Kailu and Tongliao."
"From Chaoyang, Xifuxin to Kailu, both the terrain and transportation are more conducive to large group operations 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 four units with few Japanese troops at the moment.
Division, if this division is transferred to the Linxi battlefield with relatively complex terrain, it will not be able to take advantage of the division's high degree of mechanization."
"If the fifth division forcibly advances towards Kailu, and the Japanese troops of Changtu and Lishu penetrate directly into Bayantala, plus the Japanese troops currently attacking behind Chen Hanzhang, as well as the Japanese 14th Division of Tongliao and Kailu
The regiment, led by Chen Hanzhang, is in danger of being completely surrounded by the Kwantung Army."
"This fifth division, plus the Japanese troops in Changtu and Lishu, as well as a Japanese division that is currently attacking behind Chen Hanzhang from Changling, Huaide to Zhanyu, form a formation hanging over Chen Hanzhang's head.
Three sharp swords that may fall at any time. Once the Kwantung Army thinks the time has come, it will dispatch all fronts without hesitation. Cooperate with the Japanese 14th Division in Tongliao and Kailu to separate and encircle Chen Hanzhang's troops."
