In fact, Sui Changsheng didn't know that when he attacked Jiamusi, almost no one would believe that the Kwantung Army, which had always been invincible, would suffer such a huge defeat. Even when Yang Zhen's troops invaded Jiamusi, there were still people who didn't dare I believe that as the most important military base in Northeast Manchuria, Jiamusi, where an entire division is deployed, will be easily defeated.
Because after almost losing the entire Jiamusi for the first time, no one would believe that unlike the last sneak attack, after the Kwantung Army was fully prepared, someone could still pull teeth out from under the Kwantung Army's nose.
The entire Jiamusi, with the exception of the Fourth Division Regiment Headquarters, was almost completely taken down. All the institutions in the entire Sanjiang Province of Manchuria were captured almost intact, and the complete Japanese and puppet files were seized. Follow these files and follow the clues, plus Some well-informed people pointed out that the puppet Manchukuo military and police officers were almost all captured before they had time to cause trouble.
Including the first capture of Jiamusi, the military, police and special personnel there had almost been eliminated. Although it was said that after the capture of Jiamusi, the Japanese and puppets supplemented them, in less than a year, I think It is not easy to return to the original state.
This surprise attack on Dong'anke is a different matter. Although the battle did not last long, the puppet Manchukuo personnel here are much smarter than those in Jiamusi. They have already made preparations for contingency. As early as the 11th Division lost its After contacting him, most of the files were destroyed. As soon as the peripheral battle started, all the lists were destroyed and disappeared inside the city. Du Kaishan, who had just entered the city, had no clues to arrest him even if he wanted to arrest him. .
Dong'an City is a deformed city. It was built when the Kwantung Army established Dong'an Province last year in order to strengthen the management of the so-called border zone. It turned out to be just a station on the Linmi Railway. Although the entire town is small in size, , but the situation is very complicated.
There were not only a large number of pioneering groups who migrated from Japan, but also the so-called labor plundered from the customs in order to develop the border areas, and the brothels and opium dens that prospered as a result. As for other industries, they were strictly controlled by the Japanese. Except for a few gold mining and logging industries, there is almost no industrial industry. This is because it is too close to the Manchurian-Soviet border, and the territory is full of Kwantung Army military camps.
This has resulted in the Puppet Manchukuo military and police Xiante here not only having a large number of personnel, but also the situation being extremely complicated. There are as many as five or six different intelligence agencies directly under the Kwantung Army. As a so-called national defense center, Those brothels, opium dens, and even workers had quite a number of Japanese informants and spies, and quite a few of them were even established by the Kwantung Army's intelligence agency to collect intelligence.
Under this situation, without certain experience and clues, it is simply impossible to completely eliminate the Puppet Manchukuo military and police officers here in this complex environment, and for Du Kaishan's command For this kind of field army, the most lacking thing is this kind of experience. They are not Chen Bo's social department, and they don't have much experience in the anti-special struggle. It is really difficult for a field army like them to engage in this kind of work.
However, even without much experience, the results of this dragnet investigation were quite astonishing. Not only were a large number of Puppet Manchukuo military and police officers arrested, a large number of weapons and equipment were seized, but also a considerable number of A senior member of the puppet regime in Dong'an Province, Manchuria.
Although the governor of Dong'an, a puppet Manchuria, was not captured and the guy with a keen sense of smell and quick legs escaped, he was able to capture the Japanese deputy governor of Dong'an, the Japanese director of the Dong'an Provincial Police Department, and the security chief. A heavyweight Japanese official who holds real power in the entire Dong'an Province.
Regarding Sui Changsheng's fruitful results, Yang Zhen laughed it off and told Sui Changsheng to pry open the mouths of these people in the shortest possible time. Then he pretended to turn his attention back to the entire Banjiehe Fortress. Yang Zhen pointed at the map and faced Du Kaishan and Sui Changsheng, who left and returned, said: "The entire Banjiehe fortress group is one of the so-called Northeast Manchurian defense fortifications built by the Japanese Kwantung Army."
"Although we still have no way of knowing the specific internal situation, the only information available so far shows that the Japanese army has built a huge fortress group along this line, starting from the Banjie River area in the west and ending at Honey Mountain on the edge of Xingkai Lake in the east. It’s not finished yet, but judging from the current scale, it’s quite huge.”
"This fortress group consists of two parts. One is the so-called permanent border fortification group in the Banjie River area. It is mainly centered on the Xiaolutai line in Pingyang. The other is right in front of you on the line from Miaoling to Honey Mountain. These two fortresses have a large number of There are permanent and semi-permanent fortification groups built of reinforced concrete. There are communication trenches between the fortifications to connect each other. Anti-tank trenches are dug in front of each fortification. There are also combat readiness roads and underground passages between the two major fortification groups. We can coordinate and support each other.”
"Although the Japanese fortresses in this area are not as large as the Hulin Fortress in the north and are smaller in number than the Dongning Fortress Group in the south, their geographical location is extremely important and is the key link connecting the two largest fortress groups in Northeast Manchuria. As long as we capture this fortress group, we will completely tear apart the Japanese army's entire so-called defense fortification group in Northeast Manchuria."
"Whether it is to stabilize our flanks or from other aspects, this Banjiehe fortress group must be captured. Otherwise, this fortress group lies across here and coordinates with the two fortress groups stationed in the north and south with heavy troops. It will pose too great a threat to us. It prevents us from advancing westward with all our strength."
"Moreover, the Japanese army has built a large number of fortress groups along the Ussuli River and Heilongjiang in the Greater Khingan Range starting from Hunchun on the border between China, North Korea and the Soviet Union, all the way to Hailar on the China-Mongolia border. We will inevitably encounter Japanese fortresses in future operations. group."
"Let's first use this Banjiehe fortress group to train our troops' attack capabilities and gain experience for similar operations in the future. However, you must be careful not to cause too many casualties to me. If you give up your troops to me because of this fortress group, I can't spare you if you're disabled."
"In order to cooperate with you in this battle, the military region will do its best to support you. I have given an order to Ma Qichang to mobilize a 105th Cannon Battalion to cooperate with you. I am also allocating some new artillery shells to you, as well as the ones I will bring this time. Here comes the chemical defense company that the military region has just established using self-produced flamethrowers. It will also be assigned to you this time.
"Think carefully about how to fight this battle. Although the Japanese defense force in the entire Banjiehe Fortress Group is only 1,500 people, there are a large number of permanent and semi-permanent fortification groups that can be used, and from Xingshan Judging from the size of the fortress and Fujin Fortress, there will definitely be crossfire between the fortifications."
"You must not underestimate the enemy. Remember, you must try your best to use the terrain to covertly engage the enemy. You cannot fight head-on. Even if all your troops are destroyed, you may not be able to win. Use more direct-aimed artillery during the attack. Try to think of new tactics as much as possible, and use all the tactical training you have received in three groups, one team, and infantry and artillery coordination."
Having said this, Yang Zhen looked at Du Kaishan who was staring at the entire Banjiehe area, pondered for a moment and said, "Tell me what you think, and which regiment you plan to use as the main attack group."
After hearing Yang Zhen's question, Du Kaishan thought about it carefully and said: "On the 1st, I plan to use the original base of the fourth division to form a regiment. This regiment is the first batch of troops formed in the fourth division. When encircling and annihilating the 10th Division, He has been serving as a reserve force and has a complete army with many veterans."
"When all the company and platoon cadres were training at the Fujin Synthetic Base, they participated in a simulated attack training on the Japanese Fujin Fortress that our army had already captured. It can be said that they have some experience in attacking the fortress. I think this regiment will be chosen to split the river. It is more appropriate to attack the fortress group."
"But No. 1, I think our focus now is not to choose which troops to participate in the attack, but where to choose the breakthrough point. The Japanese fortress group stretches from the Banjie River area to Honey Mountain, with a length of dozens of kilometers and a depth of two to three kilometers. Ten kilometers away, there are a large number of permanent and semi-permanent fortifications built, so it is very important to choose where this breakthrough point is."
"No. 1, I see it this way. Now my two regiments are fighting fiercely with a few troops of the Japanese 8th Division on the Hongling line. When the enemy is no more than one and a half corps, using two regiments is a bit too high. Already."
"I'm wondering if a regiment can be dispatched to go south to join the battle. I think it's better to avoid the front and use two regiments to force their way south along the Linmi Railway, capture Pingyang and Yonghe in the southwest of Mishan, and cut off the entire Banjiehe fortress group from the The connection between the Japanese army in Muling."
"At the same time, a regiment currently deployed on the line from Mishan County to Majiagang will be feinted southward, first attacking the line from Honey Mountain to Miaoling to attract the attention of the Japanese army, while the main attack group will force the crossing from Heitai to Taihe. Muling River, attack the front line of the two-man squadron, penetrate directly into the junction of the entire Japanese fortress group, cut off the connection between the two parts of the Japanese army, and then attack in sequence according to the terrain."
"This fortress group built by the Japanese army is to defend against attacks from the north of the Yangtze River. Most of the firepower points should face the east. Although flanking fortifications will inevitably be built behind them, there will definitely not be too many main defenses. The firepower points are strong The level is definitely not as good as the front. Attacking the enemy from behind should be a good choice, and it is too close to the border, so it is not convenient for us to attack head-on from the front."
"Look at No. 1, the Banjiehe Fortress Group, the Hulin Fortress Group to the north, and the Dongning Fortress Group to the south are a whole. The fortress groups are closely connected to each other, forming an overall defense posture. These fortresses are connected by mountains and rivers, and are interconnected with each other. Not only can we support each other, but the two fortresses of Banjiehe and Miaoling can support each other with artillery fire, so you think this is a fortress group."
"The defensive posture of the Japanese army means that if they launch an attack from the east bank of the Ussuri River, there will be almost no detour route. So I think their rear defense will not be lacking, but it will not be much stronger than the front. They choose to attack from behind. It can effectively increase the speed of attack and reduce our casualties."
