When Liu Yun was helpless, he had no choice but to let the Air Force Academy open first, let these students learn first, what to learn, of course, the history of the development of the aircraft, the basic structure of the aircraft, and the famous examples of the aircraft during the First World War, etc., of course, the training in the early stage is not fundamentally different from that of the ordinary army.

Moreover, Liu Daguan even made the worst plan, if the German side really wanted to get stuck, he would become the chief instructor himself, the Air Force Air Force, as the name suggests, is a unit in the air, don't say anything first, let them fly for two or three years, I don't believe that they can't train excellent pilots.

When someone was ruthless, Zheng Yuanxing suddenly came to visit, and it took a long time to tell the truth, the Red Army headquarters planned to secretly send a person to northern Shaanxi to coordinate and command the Red Army in Shaanxi and Gansu, Liu Yun was also in good spirits, and he understood after a little thought, but he also hesitated.

Liu Yun was not worried about anything else, but worried about the safety of the people he was sending, Zheng Yuanxing was also stunned, and when he was about to laugh, he reacted, and asked him a little depressedly, "Brother Weimin, have you already guessed who the headquarters will send to northern Shaanxi, how is this possible?" ”

What's so difficult about this, Liu Yun can't laugh or cry, the batch that left in July, if you guess correctly, it should be General Liu Zhaoming and Commander Lin, these two people are cattle, not long ago I heard that they have occupied Yan'an Mansion in Shaanxi, who else can really command them.

Moreover, in August, another batch of people left, if you guessed correctly, it should be Zhang Guotao's department, this chairman Zhang whose heart is higher than the sky, I am afraid that even Vice Chairman Zhou is a little unmoving, so the only candidate who can command and coordinate him and Liu Lin is Chairman Li Shengde, which is difficult to guess.

Before Liu Daguan finished speaking, Zheng Yuanxing had already given a thumbs up, with a look of amazement, and at the same time he was secretly glad that this guy was not the enemy of the Red Army, otherwise he had to kill this guy as soon as possible to prevent future troubles, so he asked a little depressed, and he thought how to deal with this matter.

Liu Yun calculated in his heart, it is already the beginning of September 1935, according to the original historical time and space, Chairman Li should be in command of the main force of the Red Army and arrived near Shaanxi, so from a certain point of view, Li Shengde should indeed set off, if he guessed correctly, he was mainly waiting for the arms in western Sichuan.

After thinking about it, Liu Daguan didn't have a good way, so he had to come up with a bad idea, so he cautiously suggested, "Chief Zheng, if I personally look at it, it is better for the main force of the Red Army to go north as soon as possible, you don't need to worry about the Yan'an area, and Zhang Shaoshuai and Yang Hucheng's department are not to worry."

Zheng Yuanxing is a sober person, just the first half of his obedience, he guessed a rough idea, was shocked for a while, and asked in disbelief, "This is impossible, right?" Vice Chairman Zhang's subordinates are not idle, and Lin and Liu, facing hundreds of thousands of troops, are really dangerous."

Zheng Yuanxing's words became quieter and quieter, and the last few words were almost inaudible, because he also thought of a possibility, so he asked very seriously, "Are you worried about the three horses in Qinghai, Gansu and Ningxia, aren't they very responsible, when Lin and Liu passed by, didn't they also do nothing?" ”

If it is purely compared to fighting, how can Vice Chairman Zhang be compared with Lin and Liu, for Zheng Yuanxing's thoughts, Liu Yun is a little speechless, inertial thinking is really terrible, Lin and Liu led the army to cross the border, first, the incident happened suddenly, Ma Jiajun himself was a little caught off guard, and second, these two people have always been rigorous in their use of soldiers, and it is difficult for others to take advantage of their flaws, and Zhang Guotao's department is not necessarily the case.

When Liu Yun explained the reasons one by one, Zheng Yuanxing was also dumbfounded, the only thing he was not sure about was how the three horses would fight hard, because if they wanted to annihilate or severely damage Zhang Guotao's troops, the idle Ma Jiajun could not do it, unless the three families jointly dispatched the elite main force, but there was a must for this.

Liu Daguan rolled his eyes, and snorted in his heart, do you want to tell you that Zhang Guotao's fate is destined to have such a catastrophe, so after thinking about it, he tried his best to tell the matter, "Brother Yuanxing, I am just guessing, Zhang Yang and the others are also considered to be famous generals in the world, if they really do it to the Red Army."

"You say, will they send someone to intercept the follow-up reinforcements, and even if I guess correctly, when Zhang Yang and the others really made up their minds, it was when Zhang Guotao's troops officially sent troops north in August, so it was natural for them to pay a lot of money for Sanma to send troops."

Zheng Yuanxing is also in a cold sweat, he knows that Liu Yun is most likely right, and he himself is in West Sichuan County, but he still knows some little-known things, Lin and Liu are two military geniuses, and they are very good at governing the army and fighting wars, while Zhang Guotao's department is much looser, it is said that there are still recruits from time to time along the way, although the troops are still marching slowly in Gansu, the number has swelled to 30,000.

Such a marching force, if it encounters a cavalry raid by three horses, there is a chance that it will encounter bad luck, Zheng Yuanxing is also a natural military strategist, and he has long been dissatisfied with what Zhang Guotao did, and he also knew that something big would happen sooner or later, but he didn't expect this day to come so quickly.

The main force of the Red Army must go north as soon as possible, Zheng Yuanxing did not say much to Liu Yun, and left the town of western Sichuan worriedly, and went straight to the headquarters of the Red Army.

Since the Red Army occupied Jinchuan, it has also rested for more than three months, and during this time the Red Army has not slept much, but has been training in military skills day and night, and in addition to the more than 30,000 people who have already gone north, less than 40,000 people have stayed in Sichuan, and it will take time if they want to go north immediately.

The difficulty of the Red Army going north, in addition to the munitions that Liu Yun guessed, there was also the problem of food, the Sichuan army had a lot of grain in Maoxian, but more and more foreigners came to western Sichuan, and there were even signs of food shortage, and it was indeed quite difficult to support the expedition of nearly 40,000 people.

The Red Army did not blame these floating population, because many of these floating populations were related to the wounded, martyrs, and supporters of the Red Army.

It is precisely because of this that Zhang Guotao's department became the second echelon of the north, and the headquarters originally thought that it was overkill, but now after listening to Liu Yun's blow, he realized that he was not properly employed, and the elite of 20,000 people would be submerged in the hands of Ma Jiajun, and Li Shengde made a decision to "go north immediately".

Even if the arms are precious, they are not as precious as 20,000 lives, and the arms can be bought again, or taken from the hands of the enemy, but once the lives are gone, they can no longer be saved.

As for the wounded and martyrs of the Red Army, as well as the four counties they occupied, namely, Jinchuan, Songpan and Lifan counties, they were all entrusted to Liu Yun, who was not polite, and in his capacity as Liu Xiang's adjutant and secretary of the provincial party committee, he directly appointed Pang Xuezhong, Tan Gengyu, Zhang Hongxi, and Liu Ebei as acting county magistrates of the four counties mentioned above, and each commanded a team of western Sichuan guards, who immediately took up their posts.

Li Shengde is a master of soldiers, and he knows the truth of the speed of soldiers, while ordering people to take part of the arms provided by Liu Yun, about 10,000 people from the vicinity of Shujing Temple to ride mules and horses and animals, straight to the Songpan prairie, and on the other hand, from western Sichuan County, and then through Mao County and Songpan, straight to the Sichuan-Gansu border.

However, just after the Red Army passed through Maoxian and was still on the way to Songpan, about three divisions of the Yang Hucheng Northwest Army took the lead in attacking Yan'an, thus breaking out the "Shaanxi-Gansu War", and the battlefield was divided into two parts, east and west, respectively around Yan'an County in Shaanxi and Dingxi County in Gansu.

Yang Hucheng and Zhang Xueliang concentrated 13 divisions and 17 security brigades, totaling more than 200,000 people, but were defeated by more than 30,000 Red Army in northern Shaanxi, first defeated three divisions, annihilated four brigades, and then encircled and sent reinforcements, and then annihilated three integrated divisions, and these three divisions were all descendants of Zhang Shaoshuai's Northeast Army.

Although the battle has not really ended, the answer has already come out, only three days, the Northeast Army, known as the elite, was annihilated by three divisions, you must know that Zhang Xueliang's department is known as 300,000, of which there are more than 10 integrated divisions, and two or three are surrounded.

The battlefield of Yan'an is easy to say, but more than 30,000 people in Zhang Guotao's department encountered the three-horse coalition army of Qinghai, Gansu and Ningxia, with a total strength of up to 110,000, but the Longzhong area where Dingxi County is located is just the junction of the Qinghai-Tibet Plateau and the Loess Plateau.

Although Zhang Guotao's troops suffered heavy losses, only more than 10,000 people remained, and they were besieged near Longxi County in the south, the reason why it was not as miserable as the later Hexi Corridor was the experience of Yingxiu Town, no matter how powerful the cavalry of the Ma Jiajun was, it was not as powerful as the group charge of modern tanks and aircraft.

In the first battle of Dingxi County, the Ma family coalition army and Zhang Guotao both telegraphed the whole country, and they all said that they were the winners, judging from the battle damage data of the two, it was mostly a two-defeated and wounded, the Red Army changed from 30,000 to 10,000, and the defeat retreated to Longxi County, the 20,000 people were a net loss, although the Ma Jiajun was hard-mouthed, they did not dare to continue to take the initiative to attack, and they knew that the loss was no less than 40,000 or 50,000 people.

Since Yan'an County and Dingxi County can't move, it depends on the reinforcements from both sides, Lao Jiang's central army is powerful, such as the brave and warlike southern Hu Zong and Xue Yuebu, which are still hanging around the edge of Sichuan and Shaanxi, as for when, it will go deep into the interior of Shaanxi and Gansu, only God knows.

Dingxi County is adjacent to Longxi County, far from Lanzhou, the provincial capital of Gansu, is about 100 kilometers, in terms of reinforcements, it is the Ma Jiajun to be more obedient, and the reinforcements of the Red Army Headquarters have to cross the Ruoergai grassland and Longnan and other areas to reach Longxi County.

After Liu Yun received the briefing on the internal war of the Sichuan army, he also took the map of Gansu and Shaanxi and pondered blindly, thinking that Zhang Guotao's troops were still easy to handle, and when the main force of the Red Army arrived, most of the Ma family coalition forces would be scattered, and once tens of thousands of Red Army troops came to the city of Lanzhou, the Ma family army would have to admit defeat immediately.

As long as Ma Jiajun agrees to admit defeat and compensate for some materials and mules and horses, the Red Army will inevitably take the initiative to withdraw from Gansu, which will take more time and will be extremely unfavorable to the matter of going north to support the Red Army in northern Shaanxi.

Liu Daguan was also very helpless, he just wanted to fly to northern Shaanxi and send some arms to the Red Army, but he could not necessarily find the right place to send them, and the only hope was that before the main force of the Red Army arrived in northern Shaanxi, Zhang Yang and the others lost their temper, preferring to be good for the Red Army than for Jiang Wei.
