Li Jiansheng's first target was not Ma Bufang, nor Ma Hongbin's brothers, but Ma Buqing.

At that time, Ma Buqing was the commander of the 5th Cavalry Division of the Kuomintang Army. Its defense areas include Wuwei, Jingtai, Gulang, Yongdeng, Yongchang, Minqin and other counties. The Fifth Cavalry Division has three brigades (two cavalry brigades and one infantry brigade), as well as an artillery regiment, an engineer regiment, and a special service battalion directly under the division.

While still on the road, in order to achieve the purpose of the surprise attack, Li Jiansheng reached an agreement with the main commanders of several front armies, and he personally led the most elite special service brigade and reconnaissance brigade of the Red Third Front Army to move forward. Zeng Zhongsheng, Yuntian and others led the main force to follow behind. Zeng Zhongsheng, Yun Tian and others originally refused, thinking that the commander-in-chief was a risky action, but they couldn't talk about Li Jiansheng, and the competition couldn't compare to Li Jiansheng, so they had to agree.

However, it was said that after nearly 20 days of secret marching, Li Jiansheng finally led two elite brigades to the periphery of Wuwei. At this time, Ma Buqing was still in the dark. Of course, this does not mean that he did not know that the Red Army was coming to attack them, on the contrary, they already knew about it. The news came from the elder brother Ma Bufang. At the same time, there are also Ma Hongbin brothers. The four horses in the northwest knew that the Red Army was really coming this time, and they wanted to stage the good show of "the four horses rejecting the grandson" back then, or the good show of attacking the Red Army some time ago, so they met again to discuss. However, what they didn't expect was that the information they found out was somewhat misunderstood. It turned out that those news referred to the news that Luo Ronghuan led the main force of the Red Third Front Army into Gansu. They didn't even find out the news of Zeng Zhongsheng and the others, let alone the news of Li Jiansheng and his party. It's no wonder that the "four horses" are not to blame. First, there were few people in this area at that time, and second, Li Jiansheng and others demanded secrecy from the beginning, and tried to choose places with fewer people to march; Forced to pass through the residential area, the local population is all under control, and it is impossible to report to the outside world. This creates the suddenness of the attack. To tell the truth, this is theoretically contrary to some of the opinions of the central authorities, but this time Li Jiansheng was ruthless and insisted on asking the troops to do so forcibly. Although Zeng Zhongsheng, who has a strong party spirit and principles, disagrees a little, but Nai Yuntian and others are hardcore supporters of Li Jiansheng, and they know that this matter is indeed very important, so they turn a blind eye.

When the "Northwest Four Horses" were discussing how to gather troops to attack the Red Army, Li Jiansheng's headquarters had quietly arrived at the designated position.

Historically, Ma Buqing's 5th Cavalry Division had the First Cavalry Brigade with Ma Lu as the brigade commander; The Second Cavalry Brigade with Han Qilu as the brigade commander and Qi Mingshan as the brigade commander of the infantry brigade, with Ma Tingxiang, chief of staff of the Fifth Cavalry Division, as the front-line commander, first set off to Jingyuan County, Gansu Province, to defend the key passes along the river. In the autumn of 1936, the Red Army marched north to Jingyuan County, Gansu Province to assemble, crossed the Yellow River into the Hexi region, and Ma Lu, as the main subordinate of the Fifth Cavalry Division of Ma Buqing, was almost without service. The horse department adopted the combat method of exhaustive pursuit by cavalry, so that the Red Army marching west had no time to rest, and even time for food and rest was rare. Despite this, the Red Army defeated Ma Bu at Jingyuan Wujiachuan and killed its front commander Ma Tingxiang at a mountain. After the remnants of the Fifth Cavalry Division retreated to Wuwei, they joined up with the army sent by Ma Bufang in Qinghai, discussed the battle plan, and assigned the two cavalry brigades of the Fifth Cavalry Division, Ma Lu and Han Qilu, to the command of Ma Yuanhai, a subordinate of Ma Bufang, and went to Yongchang, Gulang and other places to continue to encircle and suppress the Red Army. Ma Lu also participated in the siege of the camp of the Ni family in Linze, causing a large number of westward Red Army troops to be killed.

In this period of history, when Li Jiansheng and He Long were still on the way to the Long March, Ma Buqing's department also dealt heavy blows to the left route armies of the Red First and Red Fourth Front Armies. In the battle of Nijiayingzi, after Ma Lu's Wei Zhen Regiment of the First Cavalry Brigade captured General Huang Huxian, chief of staff of the Red 30th Army, Ma Wei and Wei kept it secret and treated each other with courtesy. After Ma Buqing knew about this matter, he severely reprimanded Ma Lu, and finally gave up. As for the more than 200 Red officers and soldiers who were captured, they were incorporated into his own unit by Ma Lu, and some were even awarded the posts of platoon commander and military doctor.

What surprised both Ma Lu and Ma Buqing was that the first target of Li Jiansheng's department was Ma Lu's First Cavalry Brigade of the Fifth Cavalry Division, which was currently stationed in Wuwei for recuperation!

For Ma Lu, Li Jiansheng still has some feelings. In the modern history of China, there have been many such prominent figures. On the one hand, proceeding from the interests of the landlord class and their own political status, they were loyal to the feudal ruling class and did their best, while they brutally suppressed the people's resistance and spared no effort. On the other hand, proceeding from safeguarding national interests and national sovereignty, we can stand up and resolutely resist foreign aggressors. Marlu is one such typical representative. For example, on the one hand, Ma Lu actively fought the Red Army, but also exploited the local peasants with land rent, and even plundered their property in various ways. However, in terms of cracking down on the Japanese invaders, they were absolutely unambiguous and dealt heavy blows to the Japanese invaders on several occasions. Later, Mao Weiren personally inscribed a pennant of "Anti-Japanese Heroes" and presented it to Ma Lu, which became a glorious page in Ma Lu's history. And right now, Li Jiansheng's purpose is not to meet this future anti-Japanese hero, but to see the war horse of Ma Lu's department! You know, this is the most elite force of Ma Buqing's department!

When Li Jiansheng's unit quietly arrived at the designated area, Ma Buqing, Ma Lu, and other main commanders of the 5th Cavalry Division, who still thought that the main force of the Red Army was far away, were still holding a military meeting with Ma Bufang, Ma Hongbin, and others in Qinghai. As a result, Li Jiansheng repeated the old tune, and used the night to fight again. At night, it was the paradise of Li Jiansheng's department, and the people who came were two of the four most elite forces of the Red Third Front Army. You must know that the four most elite forces in Li Jiansheng's department are the Special Service Brigade, the Reconnaissance Brigade, the Guard Brigade and the Old First Brigade. This time, one is two!

In the early morning of May 4, 1936, when the people of the 1st Brigade of the 5th Cavalry Division were still asleep, Cui Xiangdong, the commander of the 1st Battalion and 1st Company of the 1st Special Service Brigade of Li Jiansheng's Department, was the first to climb the Wuwei city wall by pickpocketing, and then quietly with the help of a few soldiers, directly killed the sentries and guards and opened the city gate. After the large group of people quietly entered the city, they each pounced according to the set goal!

Two brigades against one brigade, and two reinforced brigades against one brigade that is resting, and there is no calculation in the deliberate fight - in essence, from the very beginning, Ma Lu's department was already doomed! By the time some of Ma Lu's subordinates reacted, Wu Wei had already fallen into the hands of Li Jiansheng. As for Malu's brigade, all but a few were killed on the spot, and the rest were captured on the spot. Li Jiansheng didn't say much, and immediately took Wu Zheng's spy brigade to control the whole city, and Xu Kai led the reconnaissance brigade to take over all the war horses of Ma Lu's cavalry brigade. When Xu Kai established the Red Seventh Army in Li Jiansheng, he was only the commander of the reconnaissance company of the Red Seventh Army, and with the rapid development of the army in recent years, this heroic general has now become Li Jiansheng's number one general, and has become the commander of the reconnaissance brigade with outstanding achievements. You must know that the combat power of this brigade is only stronger than those main divisions. The soldiers are all characters who can fight when they get off their horses and can become an army when they get on their horses. Li Jiansheng asked him to receive all the war horses of Ma Lu's First Cavalry Brigade, and the purpose was also the same! No, by the time dawn, Xu Kai had already led the reconnaissance brigade -- yes, it had been renamed now, and it was called the cavalry reconnaissance brigade -- to take control of the whole city. Xu Kai is foreign this time, you know, every time he sees Shao Qianqian, his eyes are a little hot: that is the commander of the cavalry brigade, all cavalry, fast speed. Although his troops also had some war horses, the warriors could only walk more often because there were not enough war horses. This time, going home can make Shao Qianqian's eyes red!

Xu Kai was overjoyed, and Wu Zheng followed Li Jiansheng to control the radio station, cipher codebook, military map and other important confidential items of the 1st Cavalry Brigade, and seized all food and weapons. However, I have to say that this Ma family army is still relatively poor, and these weapons are really not good in the eyes of the officers and soldiers of the Red Third Front Army. Only those sabers were reluctantly transferred to Xu Kai's equipment reconnaissance brigade. After confiscating Wuwei's warehouse, suppressing a number of hardcore landlords and bullies, and some soldiers of the First Cavalry Brigade who had the blood of Red Army soldiers on their hands, especially those who had bloody hands on female Red Army soldiers, Li Jiansheng gave up. Fortunately, Wu Zheng has always grown up with Li Jiansheng, and he asked these familiar questions one by one, and then shot him directly in front of everyone! This time it kind of scared some people. As for the more than 200 Red officers and soldiers who were captured and later incorporated into his unit by Ma Lu, they were all rescued by Li Jiansheng. Wu Zheng and Xu Kai still had some opinions about these people at first, but Li Jiansheng, who was familiar with this public case, gave a slight explanation, which put the two tiger generals at ease. More than 200 people were integrated into the reconnaissance brigade and the special service brigade. As a result, the magnanimity of these two brigades can be regarded as an eye-opener for these soldiers of the former Red First Army and the Red Fourth Front Army!
