After listening to Chen Long's report on the capture of Japanese funds. Yang Zhen said with considerable satisfaction: "Your first kick to open the door is really good. It has brought so much money for the military region at once, but it has solved the urgent needs of the military region at present. Intelligence work is nothing more than daring to think and ponder, and at the same time, it is necessary to be bold and meticulous. So far, you've done a pretty good job on this point. ”

"I can accurately capture important clues from the confession of a Japanese officer, and make such an important person along the way. What it is, that's the result. However, it is necessary to shift the focus of work to military intelligence, and not to devote all of its energy to the economy. ”

"It is necessary to have economic intelligence, and it is one of the tasks I have set for you to solve some of the economic difficulties in the base areas and to obtain some urgently needed strategic materials. However, the general direction is still to focus on military intelligence work. You should make good use of this group of Japanese prisoners of war and strive to open up the situation in a short time. ”

"Kitano Takatsu and Nomura Iwa, you must use these two people. At the same time, you are carefully considering whether there are any loopholes in your plan. The most important thing in intelligence work is to be careful, not only to take into account every variable, but also to carefully ponder one's own loopholes. ”

Yang Zhen had just said this, and before he could elaborate on the next words, his words were interrupted by the sound of the staff officer's report. Looking at the staff officer who was standing outside the door and didn't know how many times he had come to ask for instructions, Yang Zhen shook his head helplessly, and could only interrupt his conversation.

Originally, Yang Zhen wanted to discuss with Long Chen about how to use this Kitano Takatsu, but at the moment he did have some doppelganger spells. Wang Guangyu and Du Kaishan asked for instructions one after another, and the hostile situation on Guo Bingxun's side changed dramatically, so that Yang Zhen could only temporarily terminate the conversation with Chen Long.

After Long Chen left, Yang Zhen carefully read the latest telegram sent from the front. Frowning, he ordered someone to find Ma Chunsheng, who was replacing Wang Guangyu, who had already gone south, to clean up and arrest the remnants of Jiamusi.

Before Ma Chunsheng arrived, the contents of these three consecutive telegrams sent from the commanders in three directions were similar, which made Yang Zhen, who was full of suspicions, open the map and compare the telegrams of Guo Bingxun and several others, and carefully pondered what the Japanese army's intention was.

After a detachment of the 11th Division and a detachment of the 4th Division of the Japanese Army retreated to the east bank of the Songhua River, they immediately began to deploy Guo Bingxun, who had crossed the river to counterattack on all fronts, with a battalion of the 5th Regiment and 6th Regiment of the 2nd Brigade, and strengthened the 1st Divisional Cadre Regiment that supplemented the two county brigades of Luobei and Suibin.

Under the command of Liu Changshun, under the cover of an artillery battalion formed by the main force of the mountain artillery battalion directly under the Second Brigade and an artillery training regiment selected from the rags transported from Jiangbei, the German-made 77-mm field artillery and the French-made 69-mm mountain artillery were relatively well selected, and under the cover of an artillery battalion formed by the French-made 69-mm mountain artillery, on the night of Yang Zhen's surprise attack on the Lianjiang estuary, he forcibly crossed the Songhua River from the Leye line in Tongjiang, thus attracting the attention of the main force of the Japanese puppet army in the Fujin area to the Tongjiang line in the north.

He personally led the main forces of the 4th and 6th regiments of the 2nd Brigade to reinforce a 150-mm heavy mortar company, a 75-mm mountain artillery company of the brigade's mountain artillery battalion, and a flat-fire artillery company to smuggle across the Songhua River from the lower reaches of Fujin to the Jieji and the front line of Xi'an two hours after the frontal forcible crossing battle began.

After crossing the Songhua River, Guo Bingxun commanded two battalions of the Sixth Regiment with Tao Jingfei, with the cooperation of the mountain artillery battalion, to the north and directly penetrated the line of Dayushu and Shagang north of Fujin County, and made a move to cut off the flank of the Japanese army that was attacking the frontal troops commanded by Liu Changshun. And he forcibly crossed the Wuding Mountain, that is, the line of Wuergul Mountain specially pointed out by Yang Zhen.

At this moment, most of the attention of the Japanese army was focused on the direction of the frontal forced crossing commanded by Liu Changshun, and part of the troops used for the flank and rear guards were also firmly attracted by the roundabout troops commanded by Tao Jingfei. The interspersed troops under the personal command of Guo Bingxun were almost not hindered and arrived at the front line of Wuding Mountain.

At this time, the Japanese army Wudingshan Fortress, which had just begun construction, garrisoned the Japanese army with only one squadron, one military police squad, and a puppet Manchurian police brigade composed of Koreans. The entire fortress has only been under construction for less than half a year, and the impact of the flood has been added. Apart from a few field fortifications made of barbed wire and sandbags, there were hardly any garrisons.

Guo Bingxun easily defeated the Japanese puppet army garrison, and rescued more than 10,000 laborers before the Japanese army realized that something was wrong and slaughtered the laborers in the fortress.

After sending a battalion to send these laborers back to the old base area west of the Songhua River, Guo Bingxun commanded the remaining two battalions to turn around and go north, attacking and advancing with all their might towards Fujin County, which was only 11 kilometers away from the first line of Wuding Mountain.

In the afternoon of the same day, that is, Yang Zhen forced the last remnants of the Fourth Division in Jiamusi, and in one fell swoop took Fujin County, which had almost no troops to defend. And immediately after going south into the territory of Baoqing, he took Baoqing and cooperated with the troops that broke through head-on, and advanced to the front line of Raohe, trying to hit Hulin in one go.

What Guo Bingxun did not expect was that after discovering that he was in danger of being attacked from both sides, the Japanese troops in front of Liu Changshun did not desperately resist stubbornly, but burned the heavy equipment that could not be carried, and after the excess food and ammunition, they quickly alternately covered the rapid retreat to the southwest through the line of Taiping Mountain. It was only after retreating into the Shimenyu line in the territory of the Rao River that he held his foothold and built fortifications.

At this time, the Japanese puppet army stationed in Tongjiang and Fuyuan, northeast of Fujin, had all moved south, and after joining up with the northbound detachment of the 11th Division that had retreated all the way to the southeast of Fujin, they all retreated to the mountainous area southeast of Raohe, and forcibly occupied all the commanding heights in the shortest possible time.

When Liu Changshun, who commanded the pursuit, entered the Shimenyu line, he encountered the Japanese army retreating all the way here, and took advantage of the terrain to resist stubbornly. Except for a few blocking actions before, the Japanese army, which had been retreating, seemed to be a different person at this time, not only desperately blocking the attack, but also constantly launching tactical counterattacks. Liu Changshun commanded the troops to attack several times, but they were all successful.

When Guo Bingxun led the fourth regiment to arrive, he found that a large number of new Japanese reinforcements had appeared in the mountains around Shimenyu. Judging from the results of reconnaissance, the Japanese troops that appeared in the mountainous area southeast of Raohe were the first part of the 12th Division of the Japanese Army stationed in Suiyang, and the four squadrons of the Eighth National Border Garrison. and part of the artillery and cavalry.

In the dangerous terrain, all the commanding heights were occupied by the Japanese army. Moreover, by this time, the Second Brigade, which had been fighting fiercely on the front line for nearly two months, was already a veteran of the division and was in urgent need of replenishment. The most critical thing is that due to the excessively fast pace of advancement, the logistics troops are still left behind on the front line of Erlongshan. The troops who arrived at the front line of Shimenyu were short of food and ammunition, and they were unable to continue their eastward advance.

In the unfavorable terrain, the shortage of ammunition and food, and the arrival of a large number of reinforcements from the Japanese army, Guo Bingxun quickly gathered his troops and withdrew to the west of the Luoli River to fortify on the spot, on the one hand, urging the logistics troops to follow immediately. On the one hand, he sent a report to Yang Zhen asking for instructions on whether to continue to advance eastward.

Compared with Guo Bingxun's initial progress, after Yang Zhen captured Jiamusi, he seized the entire territory of Huachuan with the strength of two regiments, but the progress of Du Kaishan in Baoqing through Huachuan was extremely unsmooth. On the day of entering Baoqing, they encountered a large Japanese army in the southeast of Baoqing, whose strength was at least one wing or more. Only the numbers that have been ascertained include the 11th Division of the Japanese Army stationed in Mishan and the 8th Division stationed in Muling.

On the Western Front, Wang Guangyu also encountered a large number of newly arrived Japanese reinforcements in Yilan and Boli. According to Wang Guangyu's report, its strength so far has been in addition to at least one Japanese army with more than one wing. The puppet Manchu army alone found the numbers of two infantry brigades, one cavalry brigade, and even some of the White Russian units.

After interrogating the Japanese prisoners of war captured by the reconnaissance battalion, it was learned that the Japanese troops Wang Guangyu encountered at Yilan and Boli were the 14th Division that had just been transferred to Beimanchuria, which reinforced one wing of five infantry squadrons, one wing of the search wing, and one artillery wing. Four infantry squadrons of the 8th Division, one mountain artillery squadron, stationed in Muling.

Wang Guangyu, who had only one regiment of troops at hand, immediately switched from offensive to defensive after identifying the enemy in front of him. Construct field fortifications on the spot and engage in fierce battles with the newly reinforced Japanese troops. It's just that this Japanese army is a little strange, after repelling Wang Guangyu's attack, in addition to using the main force of the puppet Manchu army with a small force of the Japanese army to launch a tentative attack on Wang Guangyu's department, the main force built a fortification under Wang Guangyu's nose.

It was not only Wang Guangyu who encountered this kind of thing, but Guo Bingxun and Du Kaishan, who were fighting on other two fronts, all encountered similar situations. In particular, the situation of Guo Bingxun and Du Kaishan is particularly similar. Once the two attacked eastward, the Japanese put up a desperate resistance. If the attack was stopped, the Japanese army did not pursue it, and only focused on building fortifications. Even when Guo Bingxun on the front line of the Raohe River shrank his forces and retreated westward, he did not even pursue the pursuit to deal with the errand.

The entry of the 14th Division of the Japanese Army into the battlefield was not good news for Yang Zhen. If this 14th Division cooperates with Mu Ling's 8th Division, Suiyang's 12th Division, and Mishan's 11th Division to launch a full-line counterattack, then with the addition of the 25th Division on the front line of the Haoliang River, which is still on its flank, it is very likely that the veteran soldiers of the division will be driven back to the north of the Songhua River.

Of course, Yang Zhen didn't know that the Eighth Division was just an empty shelf, and in fact there was only one brigade and regiment. The main force has also formed a new garrison in Japan mainland and Kannai, and the reinforcements have not yet arrived. The troops going north to Baoqing and Raohe have almost done their best.

Except for the nine squadrons that have already arrived at the front line of Baoqing and Raohe, no troops can be withdrawn. Except for the squadron that served as the guard of the division headquarters, almost all of the soldiers under Lieutenant General Tsukada Tsukada, the commander of the Eighth Division, had been transferred and became a veritable commander of the light pole.

However, the 14th Division was constrained by the limitation of transportation capacity, except for some troops that had already arrived in Yilan and Boli, the rest of the troops, especially most of the artillery, the main force of baggage troops and engineers, were either still on the railway line, or they were still waiting for shipment in Xinjing. It will take at least three to five days to reach the battlefield in full.

In the case of the total annihilation of the troops of the 2nd Division going north, the 24th and 25th Divisions suffered heavy losses in succession, and Umezu Mijiro, who had suffered heavy losses in succession, could not have been able to send reinforcements in other areas at all, so he did not dare to throw the 14th Division into the battlefield alone.

The orders received by Yang Zhen and his troops were to ensure that the Luoli River in Raohe County would flow south of the mouth of the Ussuri River, east of Shimenyu, east of the Baoqing Toad Tong River, and upstream of the main stream of the Luoli River to the south of the first line of the Wandashan Pass. The area south of the Wuken River in Boli County, south of Daotai Town in Yilan County and east of the Songhua River has absolute control rights. As for Fujin, Tongjiang, Fuyuan, Huachuan, and Yidong counties, they have actually been abandoned.

This line is a so-called high-voltage line that the Tokyo Oita Battalion requires the Kwantung Army Command to guarantee, and it is also the lifeline of the Kwantung Army. The Tokyo base camp directly told Umezu Mijiro without any subtlety that if this line was lost, then he would take the initiative to resign.

Of course, Yang Zhen didn't know these things, but what he knew was that the Japanese army's move was extremely abnormal. After the arrival of a newly added division, these Japanese troops did not advance but retreated. Judging from the various actions of the Japanese army at present, it seems that they are preparing to reconstruct a blockade line along the perimeter of their current control area.

After the map showed that the Japanese army was currently in control of the area, Yang Zhen, who had not been clear about the intention of the Japanese army's move, suddenly understood a little. This should be after the Japanese army suffered disastrous defeats in two large-scale river crossings, and began to adjust its overall strategic deployment. Although Yang Zhen did not understand the movements of the Japanese army on the Western Front, he understood the actions of the Japanese Army on the Eastern Front.

The reason why the Japanese army on the eastern front abandoned Tongjiang and Fuyuan was because they knew that most of the territory of these two counties was swamps and wetlands, and the interconnection with Raohe, Mishan, and Hulin, where heavy troops had been gathered, could only lead to the first line of Guò Jiamusi and Fujin.

If you continue to stay behind the troops, not only will you disperse the Japanese troops, but once you capture the entire territory of Fujin, it will be equivalent to cutting off the retreat of all the Japanese puppet troops in the two counties, and the Japanese puppet army in the two counties will become the turtle in the urn. Taking the initiative to give up these two county seats, which were actually isolated after Jiamusi was lost, was a helpless move for the Japanese army.

As for the stubborn resistance of the Japanese army in Raohe and Baoqing, Yang Zhen understood it as soon as he looked at the map. The Rao River is located to the north of Hulin, where the Japanese army has built huge fortifications, and Baoqing is located behind Hulin. The mountainous areas of these two counties actually played the role of covering the flank and rear security of the Japanese army in Hulin.

Based on the geographical location and the consideration of strategic depth, whether it is Raohe or Baoqing, the loss of all of them is unacceptable to the Japanese army in any case. Unless they abandon the hugely expensive, now completed, just-completed Tiger Forest Fortress Group. And this is basically impossible.

The Wandashan mountain area in the southeast of the Rao River is connected with the mountains and rivers of the Hulin Fortress, and plays a role in protecting the barrier of the northern wing of the Hulin Fortress. Once the mountainous area southeast of the Rao River was lost, the northern line of the Hulin Fortress was directly exposed to its own guns. At that time, not counting the fact that this fortress group that the Kwantung Army has been keeping strictly secret will be in danger of being completely exposed, and the most important thing is that it will form a direct threat to the entire fortress group.

In the mountainous area south of Baoqing, in addition to directly protecting the safety of the rear side of the Hulin Fortress as the depth of the Hulin Fortress, the criss-crossing railway lines and highway lines connected to Mishan are the only supply channels for the Japanese army in Hulin.

If Baoqing was all lost, the Japanese troops in Hulin and Suiyang would only be able to supply by railway through Guò Mishan. Baoqing lost it, not only exposing the rear of the Tiger Forest Fortress to himself, but also cutting off one of the only two supply lines by himself. Even the supply lines in the Mishan region were exposed to their own guns. With these circumstances, it is not difficult to understand the move of the Japanese army on the Eastern Front.

But why did the Japanese army on the Western Front move so strangely? If the Japanese troops in Baoqing and Raohe maintained such a number of troops, they would definitely not dare to transfer the second and third brigades back. In other words, his Western Front is now very empty. Why did the Japanese troops on the Western Front also retreat after the arrival of reinforcements?
