On August 7, the sixth year of Chongzhen, a big battle broke out on a grassland near the Tongtian River in the southeast of Yushu. The sons of Choktu Khan, Arslan, Gushi Khan, and Meng Qiaofang, the commander of the 11th Cavalry Division of the Ming Army, were standing on a hill in the northwest with a group of guards, watching the fierce battle between the two huge cavalry on the grassland in front of them.

According to Chongzhen's orders, Arslan selected 4,000 young men from his father's subordinates and formed an army that was completely obedient to his orders, after which he moved to Qinghai with tens of thousands of troops.

At the end of March, after Arslan accepted the armor weapons sent by the Mingren, the 4,000 guards finally took shape. At the end of April, Arslan led the army divisions to attack and swept all regions in western Qinghai, forcing them to swear allegiance to the Ming Dynasty, clearing the way for the army to enter Uszang.

At the beginning of June, Arslan led an army of 10,000 men across the Kunlun Mountains into the former Tibetan region, but the first thing they faced was not the first thing they faced. The power of Zangba Khan, but entrenched in the most powerful Baili Tusi Dunyue Dorjee in the central part of Kham District.

The Tsipzangpa regime founded by Sinshapa Tseden Dorjee was only a regime that ruled Later Tibet from the beginning, and it was not until Karma Tenchen Wangpo suppressed the local forces in Anterior and Hind Tibet that a unified force was established in Anterior and Hind Tibet. But for many toasts in Kang, it is still in a semi-independent position.

Because Kham was a buffer zone between Tibet and the Central Plains, the Tsib-Pak regime had not yet grown to the strength to resist the Central Plains, and the Ming Dynasty was not weak enough to intervene in this region. As a result, the large and small Tusi in this region were offered to both the Usizang and the Central Plains regime in order to maintain their independence.

However, with the rise of Baili Tusi, who occupied the central Kham region, it was gradually possible for the Kham region to become a unified local separatist power, and the alliance between Disi Zangba and Baili Tusi accelerated this process. According to the information that the Ming people investigated, all the large and small Tusi who were adjacent to Baili Tusi and refused to obey his orders were arrested by him and thrown into his own dungeon.

Although Baili Tusi faintly has the momentum of unifying the Kham region, Arslan and the others are not afraid that Baili Tusi will lead his troops to fight with them head-on, they are only worried about one thing, that is, Baili Tusi will cower in his lair and do not move, and when they go to crusade against Lhasa and Shigatse, they will run out and cut off their own back road.

The Tibetan areas are sparsely populated, making it difficult to raise military rations and supplies, and once the army's rear route is cut off, it will be the end of the entire army's annihilation. Therefore, the elimination of Baili Tusi was inevitable, but they did not want to waste most of their energy on Baili Tusi and ruin their plan to march into Lhasa.

Gushi Khan, who had followed Arslan for several months, suggested that there was no need to rush to attack Lhasa, and that the troops should send personnel in the Yushu area to contact the major families and Tusi in Qianzang.

In addition, in the past few years, the Tszzangpa and Baili Tusi have continued to expand their power, and the suppression of these local forces and Gelug sects can be described as boiling public resentment, and they can take advantage of it.

Of course, if such an army of theirs sat in Yushu, Disi Zangpa and Baili Tusi would not dare to make a move. Therefore, Gushi Khan once again proposed that he lead 3,000 men to garrison Yushu, while Arslan and Meng Qiaofang took the rest of the horses to retreat to Qinghai.

Then, in order to keep the gateway of Qinghai into Tibet and prevent the Ming army from entering Tibet, both the Disi Zangpa and Baili Tusi will inevitably send troops to attack Yushu and drive them out of Tibet. Arslan and Meng Qiaofang led the army back again, annihilating the attacking army in one fell swoop, and creating conditions for the next expedition.

Meng Qiaofang was still a little worried about whether there were other plans behind Gu Shihan's suggestion. But Arslan was persuaded by Gushi Khan, and the two months of getting along day and night made him feel that Gushi Khan was indeed a bright and upright Mongol, and he didn't think that Gushi Khan would have any other ideas, after all, these soldiers were under their control, and no one belonged to Gushi Khan's subordinates.

Under Arslan's strong guarantee, Meng Qiaofang finally agreed to Gu Shi Khan's plan. Sure enough, as Gushi Khan expected, when the news came out that Arslan retreated with a large army, leaving only 3,000 people stationed in Yushu, Baili Tusi Dunyue Duoji couldn't wait to move.

He was not even willing to contact the first Si Zangpa to send troops together, and he was not without thoughts about the entire Tibetan area in Dunyue Dorjee's heart. After he brutally ruled most of the Kham region, the next target was naturally Qinghai and Tibet. Geographically speaking, Yushu is also the border between Qinghai and Kang District, and how can he be willing to let the Disi Zangpa extend his influence to this area.

With his own 4,000 men and horses as the backbone, Dunyue Dorjee gathered nearly 5,000 Tusi men and horses from the vicinity, marched upstream along the Tongtian River from Derge, and arrived in Yushu on the evening of August 1. That same night, Dunyue Dorjee sent people into Yushu to demand that the Ming army retreat to the east of Kunlun Mountain, but Gushi Khan refused.

Beginning on August 2, Dunyue Dorjee launched an attack on the Ming army headquarters stationed in Yushu with nearly 10,000 troops. Yushu is just a small earthen enclosure and does not have many defenses. In the face of the attack of Dunyue Dorjee's troops, the Ming army left behind by Gushi Khan fell into a bitter battle from the beginning.

It's just that although there are many men and horses in Dunyue Duoji, they really lack the means for siege warfare. The officers of the Ming army who assisted Gushi Khan played excellent defense tactics in this siege battle, relying on hundreds of earthen houses and temporary defense facilities in Yushu to block the opponent's crazy attack in the first two days.

Dunyue Dorjee's descendants suffered heavy losses in the previous two days of attack, and their morale was greatly depressed for a while. They had never fought such a bloody siege before. Those Tusi in Kang District, as long as they surrounded the stockade, they were basically about to surrender, and a few hard-boned ones also broke the wall and surrendered. Where will they be like these people, no matter how many times they have attacked the outer earthen wall, they will always be driven out by the Ming army in the city.

The complaints of his subordinates forced Donyue Dorjee to let his descendants retire to rest, and forced the men and horses of the vassal Tusi to attack. As soon as the attacking men and horses were replaced, the Ming army in the city felt less pressure to fight. This also made the soldiers drawn from the various ethnic groups in Qinghai finally breathe a sigh of relief.

On the afternoon of August 6, the Baili Tusi army, which had finally captured a third of the defenders' positions, was stunned to hear the sound of horses' hooves coming from the northeast, and the 11th cavalry division led by Meng Qiaofang quickly routed the Tusi men and horses that had invaded the city, forcing Dunyue Dorjee to retreat with the remaining 5,000 people, and on the way to join the second batch of 3,000 fresh troops requisitioned.

However, this did not save the fate of Baili Tusi, and on August 7, the Arslan army came by detour to intercept the Tusi army near the Tongtian River. At the same time, Meng Qiaofang and Gu Shi Khan also caught up with them with men and horses, and the army led by Bai Li Tusi fell into the front and rear attacks of the Ming army.

Although the strength of the two sides in this battle was almost the same, the Ming army, with high morale and good equipment, was obviously not something that these Tusi soldiers wearing leather jackets could resist. Only half an hour after the start of the battle, Arslan, Gushi Khan, and Meng Qiaofang had already left the battlefield, watching their subordinates separate and annihilate the men and horses surrounding Baili Tusi.

In addition to Bai Li Tusi's own descendants, the other Tusi people in Kang District had already dismounted and surrendered to the Ming army after seeing that the situation was not good. As the groups of Tusi soldiers were escorted to the side of the battlefield by the Ming army, the sound of fighting in the battlefield began to gradually decrease, and the Ming army wearing red robes and the Mongols in blue coats had already controlled the entire battlefield, only a few groups of brown clothes and horses close together were exposed in the middle.

The battle lasted from 9 a.m. to 1 p.m., and it was not until the Ming army finally routed the last of the resisting troops and captured Baili Tustonyue Dorjee alive.

Facing Dunyue Dorjee, who was escorted by the soldiers and his face and body were covered with blood, Arslan, who was sitting on the horse, couldn't help but bow his head and ask him, "Baili Tusi, why are you attacking my great soldiers?" ”

Although Dunyue Duoji was captured by the Ming army, he didn't feel that he was defeated, and he was quite annoyed that he had fallen into the hands of the Ming people, so he would have such a failure. The Ming people actually didn't have many troops in their hands, and if he hadn't fought in the field, he might not have lost. As long as he returns to his own village, where can the Ming people break through their own fortress.

After hearing Arslan's question, he thought for a long time before he said respectfully: "I didn't know that the army of the Ming Dynasty was stationed here, I was just bewitched by people, thinking that a group of robbers came here, so I came to suppress the bandits with various Tusi."

When I saw the military uniforms of the adults, I realized that I had been deceived. But the adults didn't give me a chance to explain, so they chased and killed, in order to avoid the deepening of the misunderstanding between the two sides, I withdrew from Yushu with the army, but I didn't expect the adults to catch up again, and cut down most of my army.

The name of Baili Tusi in my Dunyue Duoji, but it was also canonized by the Ming Emperor, how could it be possible to move a knife against the emperor's army? I will write this incident as a melody, and send the wicked man who deceived the people to the capital to wait for the emperor's punishment of me. ”

Arslan's eyelids jumped suddenly, and Donyue Duoji raised the emperor to fight against him, after all, he was still a little hesitant when he was still young. As Dunyue Dorjee said, if his toast was canonized by the Ming Dynasty, he would not have the right to dispose of Dunyue Dorjee. But if you let Dunyue Duoji go back, wouldn't today's battle be in vain.

Arslan subconsciously took a few steps back and discussed with Gu Shi Khan and Meng Qiaofang. Gu Shi Khan didn't even look at Baili Tusi, and said to Arslan: "The emperor ordered us to come to settle Qinghai and Wusizang, this Baili Tusi is conquering everywhere in the Kang area, and is actually the next Sizangba."

Rather than waiting for him to cause trouble in Qinghai-Tibet in the future, it is better to eliminate this hidden danger now. What's more, if we want to continue to march into Lhasa, we must raise supplies and win over vassals here, otherwise before we reach Lhasa, the fortresses on the road will almost consume the strength of our army.

Kill him, and the savings of several generations of Berry Toast will be enough to allow us to continue our march without waiting for the rear to transport supplies. And those toasts who were oppressed by Baili Toast will also provide troops and guides because they are grateful to us, why not? ”

After hearing this, Arslan couldn't help but look at Meng Qiaofang, only to see that although the general of the Ming army did not express his position, he also bowed slightly to him, obviously agreeing with Gu Shi Khan's opinion.

Arslan thought for a long time, and finally gritted his teeth and called the guards around him, and took Baili Tuston Yue Duoji down, and soon a bloody head was sent over.

Arslan, after distinguishing his countenance, commanded: "His body is buried, and his head is dried in lime and packed in a box." However, I released a few more captives and told them that Dunyue Dorjee was dead and that this place had belonged to the Ming Dynasty, so that all the local Tusi would come to Derge to meet me, and by the way, they would attack Bailijia with our army..."
