When he was fighting, he was transferred back to the headquarters at this time, and his old partner Tao Jingfei didn't know the reason for transferring him back. But the truth of obeying orders as a vocation is still understood, and in a daze, he didn't know what mistake he had made, and Du Kaishan, who was replaced, took the plane that sent Tao Jingfei to replace him and returned to the headquarters. Yang Zhen, who received him personally, only gave him the battle plan drawn up by Chen Hanzhang, so he didn't have time to deal with this guy.

Looking at the battle plan in his hand, Du Kaishan was really dizzy this time, and he really couldn't figure out what No. 1 was going to do. Didn't Chen Hanzhang and Liu Changshun command the Western Front there? Why do you let yourself see the battle plan on the Western Front? Do you want to let yourself replace Chen Hanzhang? It's unlikely, Chen Hanzhang is not himself, and he can't make mistakes.

Du Kaishan, whose main combat direction is in the direction of Jilin, did not know that Chen Hanzhang was about to command an armored cavalry cluster to launch a large-scale and in-depth interspersed operation in the direction of Suidong and Suizhong in accordance with the confidentiality regulations of the Anti-Japanese Federation. He also thought that he had been transferred back to the headquarters and ordered to familiarize himself with the situation in Ximan in the shortest possible time, and that Chen Hanzhang had made some mistake and wanted to be replaced.

Du Kaishan, who was confused and couldn't figure out the situation, looked at the busy No. 1 and No. 3, but he didn't dare to ask the headquarters what it meant to transfer himself back from the front line at this time. I could only take the battle map and the battle plan drawn up by Chen Hanzhang in wonder, and study and ponder it by myself.

Du Kaishan, who was brought back to the headquarters here, was confused, and after receiving the order from the headquarters, Chen Hanzhang immediately handed over the command to Liu Changshun. and transferred Wang Minggui and Yang Jicai back to their headquarters. As for the task of encircling and annihilating the Japanese troops in the territory of the right banner of Sunit and the white flag, it was entrusted to the division commander and political commissar of the 17th Division under unified command.

After explaining in detail to Liu Changshun his plan and plan for the next battle in the front, Chen Hanzhang, who was a little uneasy, went to Wang Minggui to talk to Yang Jicai alone, and personally drafted a top-secret telegram to the headquarters before rushing by plane to the roundabout troops that had been assembled in the territory of Sunit Left Banner.

At this time, the roundabout troops assembled there had already been prepared. The two tank regiments of the 1st Panzer Division, 180 tanks, 60 armored vehicles, 340 half-track armored vehicles, and 300 American-made international trucks have all been prepared for a long time.

The T26 tanks in the two tank regiments of the 1st Armored Division have been replaced by the BT-7 tanks in accordance with Chen Hanzhang's requirements. The trucks of the divisional infantry regiment had long been replaced by German-made half-track armored vehicles transferred by the Soviet Union and the British.

The division's artillery regiment and anti-aircraft artillery regiment have been modified with Italian tanks, and all equipment has been completed. The division is now fully manned and well-equipped. If you don't count the field refueling trucks and logistics support trucks, the whole division is already fully mechanized.

And the two cavalry brigades, each in addition to their own mounts, before the departure of the headquarters made great efforts to the two cavalry brigades, a batch of additional horses. Although it did not reach the point where each person had a spare horse, each of the four subordinate cavalry battalions had a hundred spare horses. For long-distance runs, whether the horsepower can be guaranteed is quite crucial.

The equipment of the 5th Division was also adjusted accordingly according to the task. In addition to the Soviet-made Gass trucks of the division's automobile battalion, all of which were replaced with American-made Dodge ten-wheeled trucks, the headquarters also replenished the division with a large number of pack horses. The regimental-level command organs are all equipped with an American-made jeep and a German-made officer command car converted into a radio car.

Although most of the American-made equipment was seized by the Soviets at the beginning of March, some were still given to the cars. Of the first batch of 100 jeeps aided by the United States, in addition to 30 for the Advance Army, the remaining 70 were strengthened by Yang Zhen to the roundabout troops. There were also twelve German-made officer command vehicles exchanged from the Soviets.

The divisional artillery regiment was joined by a 150-mm heavy mortar battalion in addition to the original formation. The engineer battalion was added by two companies to the original three companies. Together with the regimental engineer company, the division's engineer establishment actually reached eight companies.

The 13th Automobile Regiment, which served as the Fifth Transportation Division, was also fully loaded, and all of them were the latest American-made Dodge 10-wheel trucks and Wanguo 5-ton trucks. All the automobile soldiers of the regiment are veterans with at least one year of military experience. And each car, equipped with a co-pilot.

Not only the five divisions, but all the participating units, except for the cavalry, had one American-made jeep per regiment. Command structures at the regimental level are equipped with radio cars. The whole army was made of German-made steel helmets, and the amount of ammunition was sufficient. The whole army held back its strength and wanted to fight a decisive battle with the Japanese army.

These troops, as well as a large number of attached equipment, have been assembled in the Sunit Left Banner. All the equipment has been overhauled and in the best condition. And taking into account the operational needs, in addition to the fuel trucks, each tank of the 1st Panzer Division was equipped with two spare oil drums.

According to Yang Zhen's request, the roundabout troops relied on the materials they carried, and the whole army, excluding fuel and artillery shells, could ensure self-sustaining capability for at least 15 days without relying on airdrop supplies from the rear. There is no way, with such a large force, it is difficult to meet the supply needs in the predetermined combat area.

It is precisely in consideration of the Daqingshan guerrilla base area and the Jinsui Military Region that under the frequent sweeps of the Japanese army, the losses are quite heavy, and it is difficult to support the supply of such a large force. The entire Suiyuan area is barren and poor, and the grain production is not much, so before the roundabout troops attacked, the Anti-Japanese Federation tried to find a way to carry an extra batch of materials as much as possible.

Moreover, among the materials carried, there was also a batch of weapons and ammunition for the Daqingshan guerrilla detachment, as well as gas masks. In the continuous sweeps launched by the Japanese army last year, the extremely rare large-scale use of poison gas by the Japanese army was one of the main reasons for the failure of the counter-sweep in various base areas in North China.

There were a large number of captured Japanese-made gas masks and a large number of anti-gas equipment in the Anti-Japanese Coalition, and the Kwantung Army's gas warfare had nowhere to play. However, the battlefield in Guannai was different, whether it was the troops of the 18th Group Army, the New Fourth Army, or the army of the Nationalist Government, almost all of them were severely lacking in anti-poison equipment.

However, whether it was in the offensive and defensive frontal battlefield or in the sweeping of the battlefield behind enemy lines, the Japanese army regarded poison gas warfare as a killer weapon, and the large-scale use of chemical weapons has become a common phenomenon of the Japanese army on the Chinese battlefield. It is precisely these chemical weapons that have caused considerable casualties to the Chinese army.

Many of the battles that fell short were not because the Chinese army was not brave, let alone because the Chinese were afraid of death. In addition to some of the problems that arose in command, many of the reasons for the defeat in the battles were because of these chemical weapons. The lack of anti-poison equipment, the lack of even the most basic substitute towels, and even the lack of necessary anti-drug knowledge, have brought unbearable costs to the Chinese army and the Chinese.

In the past, the central authorities had asked the Anti-Japanese Federation to allocate some gas masks to various base areas behind enemy lines. It's just that at that time, the Anti-Japanese Federation's own reserves could not meet the needs at all. Although Yang Zhen pulled out a part of the combat troops, it could not meet such a large number of needs. It was only after the Soviets sold a batch that the dilemma was largely resolved.

This time, the Anti-Japanese Federation specially transferred 2,000 German-made gas masks from the Soviets to the Daqingshan guerrilla detachment. On the Soviet-German battlefield, although everyone said that they all had the ability to fight poisonous gas, but under the fact that everyone had the ability to retaliate on a large scale, no one tacitly used it. For the Soviets, these gas masks were of no use to the Soviets on the Soviet-German battlefield, so it was better to take the opportunity to get something from the Anti-Japanese Union.

The Soviets not only handed over all the captured German gas masks to the Anti-Japanese Union. At the end of January, they also sold 5 million US dollars, 5,000 tons of wheat, 10,000 tons of corn, 3,000 tons of meat, 300,000 gas masks in their own stockpile, and a batch of anti-poison equipment to the Anti-Japanese Federation.

After the arrival of this batch of supplies, in addition to redressing the advance army, Yang Zhen handed over a lot of parts to various base areas in the Guannai. Before the detour troops set out, Yang Zhen allocated 2,000 bodies to the roundabout troops to carry and transfer to the Daqingshan guerrilla detachment according to the current strength of the Daqingshan guerrilla detachment.

After Chen Hanzhang arrived at Sunit Left Banner, he held an operational meeting to deploy the combat plan. At 4 o'clock in the morning of the 26th, the group was interspersed with a roundabout way, with the 1st Armored Division, the 1st Tank Regiment and the 1st Cavalry Brigade leading the left and right respectively, and the troops were divided into two routes along the border of Outer Mongolia, and from the edge of the Hunshandak Sandy Land directly into the line of the Siziwang Banner and the Maomingan Banner.

At this moment, the main force of the Japanese army and the Mongolian frontier army are in the fierce battle between the Sunit right banner and the anti-coalition forces that are breaking through the territory with the white flag. In this direction, only after the battle of Keshiketeng Banner last year, Li Shouxin, the commander-in-chief of the puppet Mongolian army, who was beaten into a bare-bones commander, painstakingly collected a group of bandits in the Yin Mountains and reorganized two cavalry divisions of the puppet Mongolian army.

These puppet Mongolian troops, who have basically no combat effectiveness and are more than capable of disturbing the people, have seen such a large formation. Seeing the tanks rushing across the mountains, they collapsed on the spot without even a decent resistance. Chen Hanzhang took a roundabout interspersed with troops, and almost did not encounter any resistance along the way. The troubles brought by these puppet Mongolian armies are not as much as the troubles brought by the terrain along the way.

The puppet Mongolian army collapsed at the touch of a button, which only increased Chen Hanzhang's worries. Because these scattered puppet armies are not worth his time to pursue. But these are all puppet troops of cavalry, but they can report to the Japanese army. With the efficiency of the Japanese army's actions, they would not sit idly by and ignore the whereabouts of the roundabout troops.

With most of its own forces on the Eastern Front and a relatively empty force in Suiyuan, a large-scale mobilization is unlikely. However, according to the change in the shape, adjusting the defensive posture is definitely done. Especially if it still occupies favorable terrain, at least for the time being.

If the Japanese army really found itself to fight a decisive battle, Chen Hanzhang would not only be in a hurry, but also very excited. With the strength and strength in his hands, even if he comes to a division, there is nothing to worry about. However, what made Chen Hanzhang anxious was that if the Japanese army blocked the passes of Yinshan in advance, it would cause great trouble to the roundabout troops to move south over Yinshan, and even delay the progress of the entire campaign.

Chen Hanzhang, who knew that time was victory and time was the fighter, did not order the pursuit of those puppet Mongolian troops that broke on the spot. Instead, he commanded the troops to gallop westward, making no stops except for a short break to allow tank drivers and truck drivers to rest.

And this road is a grassland and Gobi landform lacking rivers, which also created innate conditions for this interspersed force of the Anti-Japanese Federation to quickly assault. On the flat terrain of the steppe and the Gobi, it is suitable for the anti-United Nations armored forces to carry out large-depth interspersed operations.

Although Chen Hanzhang also knew that this kind of terrain was only a part of the terrain he might encounter in this battle. The real test is still in the back across the most precipitous Daqing Mountain Range in the middle of the Yin Mountain. But after all, this is a good start for Chen Hanzhang's interspersed troops.
