Jining is too important for the entire Japanese army in Suidong and Suinan. For the 110th Division and the 26th Division, which were in the midst of a bitter battle in Chadong and Chaxi, Jining was even equivalent to a lifeline. Once Jining is lost and the 69th Division is lost, then the entire North China Front Army will be completely divided in the Chahar and Suidong battlefields, together with the northern Jin Dynasty.

Faced with the complicated battle situation and the importance of Jining to the entire battle situation at the moment, Okamura Ningji did not dare to be careless. He even sent Lieutenant General Anda 23, chief of staff of the front army, to Linfen to supervise the assembly of the 41st Division. The four infantry battalions and two artillery squadrons of the 15th Division, which had arrived in Taiyuan, did not wait for the arrival of the 41st Division, but strengthened the three infantry squadrons drawn from the 4th Brigade of the Independent Mixed Brigade to go north first.

Okamura Ninji's death order to Shimizu was that the troops of the 41st Division must complete the assembly within two days, pedal the car, and must reach the Jining line within three days. If he is unable to complete the orders of the front army, he will directly apologize to the emperor for his seppuku.

At the time when Okamura Ningji was nervously adjusting his deployment, and at the same time receiving a report of the encounter between Yi Liangpin and the main force of the 69th Division on the front line of Jining, Chen Hanzhang, who had just left Daqingshan, did not take any rest and recuperation, accelerated the speed of the march, and led his troops directly into Zhuozi Mountain.

On the one hand, he sent a report to Liu Changshun, who replaced him, asking him to invest all his vital forces from the breakthrough that had been opened in accordance with the plan he had formulated before leaving. Concentrate no less than two tank battalions, plus the strength of an infantry division, and force their way to the area east of Jining.

At the same time, a report was sent to the headquarters, hoping that the headquarters would coordinate the advance march and draw out no less than one brigade of troops to launch an attack from Kangbao to Shangyi. He also coordinated the troops of the Taiyue and Taihang Military Regions in the Guannai to launch a large-scale sabotage battle on the Tongpu railway line, entangled the Japanese reinforcements, made it impossible to assemble along the line, and delayed the arrival of the Japanese reinforcements.

After receiving Chen Hanzhang's telegram, Yang Zhen immediately began to coordinate the follow-up support tasks. Two squadrons of attack aircraft, two squadrons of Il-4 bombers, one squadron of fighter planes, and one squadron of transport planes were transferred from the air force to Yan'an Airport and the newly recaptured Guisui Airport.

These air units were specially responsible for bombing the Tongpu Railway and carrying out battlefield interdiction missions around the Jining battlefield. Although the number of attack aircraft in it is not large, this is already one of the few attack planes that can be put into use immediately, one-fifth of the strength of the Anti-Japanese Federation.

The tactical aircraft provided by the British arrived only at the end of last month, and although the aviation was quickly refitted, it will not be available on the battlefield until next month at the earliest. The American-made A20 attack aircraft, which are the main force, cannot be fully put into use on the battlefields of northern Shanxi and Suinan, and must also take into account other directions.

In desperation, the air force, which also has no choice but to take advantage of the fact that it has completely stopped carrying out air raids on the Japanese mainland, and transfer the remaining 56 Il-4 bombers to Yan'an for use as attack planes. As for the modified French MS 406 aircraft, the range is too close.

Even if a temporary airport is built to take off in the Shenmu area, which is closest to Suinan in the Shaanxi-Gansu-Ningbo border region, the flight distance cannot reach Jining. Taking off from Yan'an Airport, it is impossible to reach the Tongpu Railway. Only Guisui Airport can be used as a take-off combat base to provide air support in the direction of Jining.

Fortunately, Guisui was very close to Jining, and Mu Changqiu was at Guisui Airport and captured a large amount of aviation fuel stored there by the Japanese army. In a short period of time, there is no need to find a way to transfer fuel from the rear. Otherwise, even if Guisui is very close to Jining, the airport there cannot be put into use at all because it cannot transfer large quantities of fuel and other materials in a short period of time.

In addition to mobilizing a large number of aviation troops to provide air support on the Jining battlefield, Yang Zhen hesitated and transferred the reserves of the last division in Linxi to the Western Front. In addition, in coordination with the central authorities, the original plan for the local armed forces of the Taihang, Taiyue, and Jinsui Military Regions to cooperate with the Suinan operation will be carried out to the best of their ability.

At the same time, Yang Zhen told Chen Hanzhang in a telegram that he and the Eastern Front cluster, which was interspersed in the southeast direction, should not rush directly into the Jining battlefield. Is it possible to consider using its tanks and cavalry clusters to find fighters to penetrate directly into the front line of Fengzhen and completely block the passage of the Japanese army in northern Shanxi to reinforce the Jining battlefield.

In the direction of Jining, although Yi Liangpin's troops are weak at present, he cannot complete the encirclement and annihilation of the 69th Division. However, by taking advantage of its mechanized troops, it is still possible to contain the 69th Division in a short period of time. Zheng and Yi Liangpin's troops are insufficient, so the troops with white flags can take advantage of the gaps that have been opened to forcibly penetrate and penetrate directly from the left flank of the Jining battlefield.

After receiving Yang Zhen's telegram, Chen Hanzhang, who had already arrived at Zhuozi Mountain, immediately understood No. 1's idea after carefully analyzing the surrounding enemy situation and the reinforcements that the Japanese army might mobilize. The seizure of the front line of Fengzhen completely blocked the road for the Japanese First Army in Shanxi to go north for reinforcements, and the entire Suinan and Chaxi battlefields became an isolated piece.

The troops with the white flag have completed the encirclement of the 26th Division, and are fighting fiercely with the 110th Division dispatched from the front line of Huade and Shangdu, while the 69th Division has been inadvertently entangled in the Jining line by Yi Liangpin. Before the arrival of new Japanese reinforcements, the entire northern part of Jinbei was almost wide open, except for the independent 3rd Mixed Brigade that was scattered to serve as garrisons in various places.

Fengzhen is the gateway to Suinan and the throat road from northern Jin to Suiyuan. If it is this rare fighter, there will be a time difference and seize the front line of Fengzhen. According to the topography of northern Jin, it is completely possible to completely block the road for the Japanese army to go north for reinforcements. The most critical thing is that the supply lines of the Japanese army on the Suinan and Chaxi battlefields can be cut off.

However, to seize the front line of Fengzhen alone, Chen Hanzhang always felt that the action was still a little too small. Fengzhen is still too close to Jining, and his own troops are insufficient, once Fengzhen's front line is broken through by Japanese reinforcements, it will bring considerable pressure to the entire Jining battlefield.

Moreover, the terrain of Fengzhen is not too favorable. Even with the addition of troops on the Western Front, their own forces are quite limited, and under the terrain of Fengzhen, it is impossible to fortify everywhere. The Japanese could completely bypass the frontal blocking position and break through their flank in a roundabout way.

After carefully examining the enemy-friend situation around Jining on the map, as well as the living forces of the Jinsui Military Region and the Taihang and Beiyue Districts, he set his sights on Datong, the gateway to northern Jin, south of Fengzhen. If Datong can be taken, the entire Suinan battlefield will have a relatively broad depth.

There is no need to be in danger that if the Japanese army breaks through Fengzhen, they can directly pounce on the back of the Jining battlefield. The most important thing is that Datong is the intersection of the Pingsui Railway and the Tongpu Railway. Taking Datong is equivalent to cutting off the two railway lines that the Japanese army can use. From the Liangcheng line, there is still a highway between Datong and can be used.

At present, the frontal battlefield in the territory of the white flag and the right banner of Sunit has already seized the initiative. The headquarters transferred another division of troops to strengthen the frontal battlefield on the Western Front. After the main force of the 110th Division was dispatched to rescue the 26th Division, there were actually not many troops left to defend the passage from the frontal battlefield to Jining.

If Liu Changshun can grasp the fighter, then he can increase his troops on the Jining battlefield in time. Now that you've made up your mind to take a gamble, let's just bet bigger. He led the team directly into Fengzhen, and the troops commanded by Mu Changqiu on the western front went straight to Datong. Taking advantage of the fact that the Japanese army in the entire Suinan is now attracted by the Jining line, a large in-depth interspersed detour to the south.

After thinking about it, Chen Hanzhang, who made up his mind to take a gamble, quickly adjusted his battle plan. The order had already captured Guisui and was advancing eastward, and at this time the Western Front group, which had already reached the line of the Western Qingmen, did not need to continue eastward. In the west of Liangcheng County, it turned south and forcibly entered the territory of Shanxi from the mouth of the killing tiger, and forcibly advanced in the direction of Datong along the highway from Youyu to Datong.

Yi Liangpin, who had already fought with the Japanese army in Jining City at this time, was ordered to stubbornly entangle the main force of the 69th Division and wait for reinforcements from the frontal attack troops. Chen Hanzhang's order to Yi Liangpin was not to let the 69th Division slip away, but also to hold on until the frontal reinforcements arrived.

Chen Hanzhang himself took the rest of the troops, bypassed the Manhan Mountain through the west bank of Daihai, and went straight to the direction of Fengzhen. At this moment, Guisui has been taken, and the Jinsui Military Region is besieging Baotou. Liangcheng is only the strength of a squadron of the Japanese army, and there is no need for Chen Hanzhang to make a big move, even if he stays there temporarily, it will not affect the battle situation.

Instead of passively waiting for the approval of the headquarters, Chen Hanzhang has begun to implement it gradually while reporting. His troops did not wait for a rest, and immediately turned around and took the tanks as the lead along the east coast of Daihai, and forcibly interspersed in the direction of Fengzhen at the fastest speed. Mu Changqiu, who received the telegram over there, had also completed his turn.

By the time Yang Zhen received the report, Chen Hanzhang had already begun to act. Looking at Chen Hanzhang's report, Yang Zhen was quite satisfied that Chen Hanzhang was able to comprehend his strategic intentions so quickly. As for the issue of liaison between Chen Hanzhang's unit and the Shanxi troops, Yang Zhen was not worried.

Before Chen Hanzhang set off in a roundabout way, the headquarters had already handed over to them all the passwords and radio frequencies for the liaison between the Anti-Japanese Federation and the troops in the Jinsui, Taiyue, Taihang, and Jinchaji Beiyue districts. The roundabout troops can communicate with all the troops behind enemy lines in Shanxi at any time.

At present, the left-behind corps of the Jinsui Military Region, as well as the troops of the Jin-Cha-Ji Beiyue District and the Jizhong Military Region that have been withdrawn to northern Shanxi for recuperation, have completed their assembly on the Pinglu and Guyuan lines. At any time, it can cooperate with the southward detour troops commanded by Chen Hanzhang to fight on the front line of Datong and Fengzhen.

These troops are familiar with the terrain and are well-informed, and with their cooperation, Chen Hanzhang's roundabout troops should not have any big problems. The only thing to worry about is that if Chen Hanzhang can really win Datong, then he will really stab the soft underbelly of the entire Japanese army in North China.

If Yi Liangpin raided Jining, it was on the seven inches of the Suinan battlefield. Then this Datong, the headquarters of the Mongolian Xinjiang garrison, is the weakness of the entire Japanese army in North China. Jining was lost, and the connection between the entire Suinan battlefield of the Japanese army and northern Jin was cut off. The Japanese army on the Suinan battlefield will be cut off from northern Jin and become a lone army.

But if Ke Datong is lost, not only will the Suinan battlefield be completely cut off. Moreover, the flank of the Japanese army in the Chanan battlefield was also under the threat of the Anti-United Nations. If necessary, Chen Hanzhang could command the troops at any time, along the Sanggan River valley or the Datong to Zhangjiakou section of the Pingsui Railway, all the way to the back of the Japanese army in Zhangjiakou.

And if Chen Hanzhang really appears in this direction, according to the current extremely tight front in the entire Chasan, there is a possibility of collapse at any time. If Chen Hanzhang chooses to continue south, then Taiyuan, and even the entire Shanxi Province, may be within the attack range of the Anti-Union at any time.

The most important thing is that Datong is the gateway of Shanxi, and winning the Datong line means that the door of the entire Shanxi has been opened. Shanxi is located on the Loess Plateau, with rivers and mountains on the surface, facing the Yellow River and northern Shaanxi in the west, and looking down on the North China Plain across the Taihang Mountains in the south. After taking Shanxi, the entire North China Plain was under the guns of the Anti-Japanese Union.
