These puppet armies mainly include several puppet Mongolian cavalry divisions under the command of the Mongolian Dewang totaling 20,000 or 30,000 people, as well as more than 10,000 puppet troops of the puppet "Eastern Hebei Defense Communist Autonomous Government", for their incoming attack, the headquarters of the Red Eighth Army chose a-for-tat confrontation without any tricks, and more than 30,000 people of the advance division who had just arrived in Tianjin to join the independent division put on a knife to kill chickens, and under the excellent command of Su Yu, more than 10,000 puppet troops in eastern Hebei were annihilated in just half a day, more than 8,000 people were captured, and the division advanced into the eastern Hebei Plain by taking advantage of the victory.

Compared with the puppet army in eastern Hebei, the puppet Mongolian cavalry that comes and goes like the wind is much more troublesome, if the previous Red Army encounters, even if it can win, it will definitely take a lot of time, and it will suffer a big loss if you are not careful, but now the Red Eighth Army has the king of land warfare that completely disappeared the cavalry on the battlefield in history - tank, although it is a thin-skinned Japanese product, and it is also mixed with a large number of copycat version of the "armored" car, but for the pseudo-Mongolian cavalry with almost no anti-armor weapons and general ignorance and superstition, After encountering this kind of "Iron King Eight" that can't be beaten and can't run, they instantly lose the courage to resist, and even many people are stupid when they see this kind of steel monster for the first time, and they forget to even run away, and even kneel down and kowtow, while some brave guys will only stupidly wave their sabers and slash at the turret of the tank

As a result, the armored brigade of the Red Army commanded by Hu Lian achieved eye-popping results in its first battle -- more than 3,000 enemy troops were killed and wounded at the cost of zero casualties, and more than 20,000 were taken prisoner

More than 20,000 are mainly Mongolian prisoners of war, at least half of them do not know Chinese, if it was the former Red Eighth Army would be very big, fortunately, at this time there were just some Mongolian underground party members in the Pingjin area secretly active, with their help, and the previous fiasco has made these pseudo-Mongolian prisoners of war frightened, naturally all obedient and did not dare to make trouble.

King De had a high prestige in the western grasslands of Inner Mongolia, and his defeat shook the major shili on the grasslands of Western Mongolia, among which Yun Ji, a patriotic general of the Mongolian army who was famous for leading the "Bailingmiao Rebellion", took the initiative to bring troops to join after hearing the news, which made Hu Weidong very happy, and immediately appointed him as the commander of the cavalry brigade directly under the Red Eighth Army, and Suo Libo, a veteran Mongolian party member who had been engaged in the labor movement for many years, served as the brigade political commissar.

And Bai Haifeng, the captain of the Mengqi Security Corps under Fu Zuoyi, as a secret member of the Red Party, finally made up his mind after learning the news, and after revealing his identity in front of his subordinates, he came to Tianjin with more than 1,000 subordinates who were willing to go with him

In fact, Hu Weidong did this on purpose, because he knew Bai Haifeng's historical experience and it was not appropriate to reuse it too much. Bai Haifeng joined the party in 1923, but in the following 20 years, he continued to be promoted, and finally became the commander of the army, but he did not lead the people to return, until 1949, when the general trend of the Kuomintang has gone, he led the people to "revolt" under the persuasion of the United Front personnel, so in the eyes of Hu Weidong, this guy is not trustworthy, if it were not for the number of Mongolian cadres is too small, and people have brought some soldiers over, he is not even willing to give the position of regiment commander

As long as he is a normal person, he will inevitably be a little dissatisfied if he is treated like this, but Hu Weidong is not afraid at all, anyway, there are examples of Mao Zetan being demoted and used in the past, and no one can protest because his official position is too small, and if he has a different heart because of this, then Hu Weidong will just get rid of it to prevent future troubles, and if the key object of prevention can successfully rebel, then Hu Weidong will be too incompetent

Soon Hu Weidong was surprised to find that the Mongolian cadres were actually related to each other, and after asking, he learned that they were all from the Tumut Banner of Inner Mongolia, and they had all received cultural education at the Tumut Higher Primary School in Guisui City (now Hohhot), which was also the only specialized school for the Mongolian nationality at that time. Since there is not much education in the Mongolian steppe, it is natural that the graduates of this primary school have become the main source of Mongolian revolutionaries, and this primary school only recruits Tumuts, so most of them are related by marriage from the beginning, and there are many examples of marriage between classmates, so it is not surprising that all party members from Western Mongolia are related to each other...,

"It turned out to be like this, but after all, it is not a good thing, they have a close relationship with each other, once they hold together, they will become an iron plate that cannot be splashed by water, and once they are close to each other, it will be very difficult to deal with it." Hu Weidong thought for a while and decided to actively recruit party members among the Han Mongolian nationality, and to set up Mongolian language training courses in the army to train Han cadres who were specialized in ethnic work, and at the same time vigorously promoted and converted advanced elements from lowly backgrounds among the prisoners of war who had made meritorious contributions to war, so as to prevent the Tumut family from continuing to dominate in this way.

It is precisely because of this consideration that Hu Weidong did not apply the strength of the infantry brigade and regimental level of the 15th Red Army to Yun Jixian's independent cavalry brigade, but according to the practice of this era, the cavalry unit only has half the strength of the infantry unit at the same level, that is, more than 4,000 people in a brigade and more than 1,000 people in a regiment. While the rest are dedicated to raising horses

The Japanese army, also deeply shocked by the strong combat power shown by the Red Army, so they did not dare to send troops into the pass recklessly, but in this way the army's air force could not bomb Fengtai, and in desperation, the Japanese land minister Terauchi Shouichi had to bow his head and ask the navy for help, after the army chief of staff Prince Zaihito personally intervened, the navy was worried about incurring the emperor's guilt, so it reluctantly agreed to send aircraft carriers for air support (if the land-based naval aviation troops in Dalian were dispatched, it would prove that they were only deliberately making things difficult for the army if they did not send them before, Therefore, the navy would rather dispatch aircraft carriers than insist on not enlarging the company's planes to Fengtai. and escorted a division of the army to land in Tanggu. However, the contradictions between the Japanese army and navy in this era were not ordinarily large, and the navy not only dispatched only two light aircraft carriers, the "Fengxiang" and the "Longxiang," but also drove slowly and leisurely along the way, and it actually took three or four days to sail from Japan to the sea off Tanggu, the reason was actually to save fuel
