Lin Chengxiang's Twentieth Army, along the Lancang River, went north and easily occupied Mangkang.

This place is not subordinate to Wusizang, but to Duogan, which was not originally the combat mission of the Yunnan army, but Mu Qiyuan was worried that once the Mongolian and Tibetan coalition army went south and cut off the back road of the Ming army, it would put the Ming army in a dangerous situation of fighting on both sides, so Mu Qiyuan sent Lin Chengxiang to solve the problem of returning first.

Just like Chayu, Mangkang is just a small city, because it is located at the junction of Wusizang, Duogan, Yunnan, and Sichuan, the number of Han people is very large, although the Tibetan riots also have an impact on Mangkang, but the Han people spontaneously organized, in the case of the number is not at a disadvantage, the Tibetans have little to do, before the arrival of the Twentieth Army, the Han people are basically in a semi-autonomous state.

Lin Chengxiang's arrival was warmly welcomed by the Han people in the city, and before the Ming army launched an attack, the Han people themselves opened the city gate to welcome Lin Chengxiang into the city.

After Lin Chengxiang entered the city, he slaughtered and drove out the Tibetans in the city, turned Mangkang into a pure Han castle, and established a local armed force composed entirely of Han Chinese, which was led by the 20th Army, which provided them with sabers.

Hearing that the army was going to attack Kemu (now Qamdo) in the north, the Han people introduced the situation of Kemu to Lin Chengxiang one after another, and also drew a road map for Lin Chengxiang.

Kemu is located in the southeast of Dogan, west of Usizang, is the place of governance of Dogandusi, and it is also a place that Tanju Wangpo did not conquer.

Originally, there were three major toasts in the local area: Baili Toast, Lin Cong Tusi and Dewang Toast, among which Baili Toast was the most powerful, the three major Toasts both fought with each other and cooperated with each other to maintain the apparent peace in this area, and their power gradually expanded to the middle of Duogandusi, and Yushu had long been their sphere of influence.

After the Mongols and the Shuote tribe entered Uszang, they had a very close relationship with the Gelugpa Yellow Sect, and the Great Khan Tulu Baihu was regarded as a "great teacher" by the Yellow Sect.

In order to help the Yellow Sect, Tulu Baihu and Dan Zhen Wangbo fought several battles, and after defeat, he retreated to the area of Kemu, and he relied on the strength of the Mongol cavalry to officially establish a foothold in Kemu.

Since Bai Li Tusi, like Tan Zhen Wangbo, believed in Bai Religion, Tulu Baihu's anger at the military defeat was vented on Bai Li Tusi's head, and he united Lin Cong Tusi and Dewang Tusi to eliminate Bai Li Tusi's army and divide up Bai Li Tusi's land, slaves and property.

The current guest wood is the world of Tulu Baihu, Lin Cong Tusi and Dewang Tusi, Lin Cong Tusi and Dewang Tusi each have 10,000 Tibetan soldiers, and Tulu Baihu has 15,000 Mongolian cavalry, the most powerful.

When the twentieth army marched to Bangda, there were 5,000 Tibetan soldiers in the woods.

Bangda, like Mangkang and Kemu, is located on the east bank of the Lancang River, a typical canyon topography.

Lin Chengxiang knew that the Kemu garrison was 35,000, or even more than the number of the Ming army, and he had to eliminate the Mongolian and Tibetan armies one by one and reduce the number of the Mongolian and Tibetan coalition forces, so he immediately besieged the city and hoarded heavy troops in the east and north of Bangda City, facing the west and south of the Lancang River, and was restrained by cavalry.

These Tibetan soldiers, knowing their true situation, usually scare the farmer is almost the same, and they have little combat effectiveness, otherwise in the chaotic period of Wusizang in the past few years, who doesn't want to take the fire and expand their chassis?

When the Tibetan soldiers saw a large number of Ming troops, it was estimated that the Ming court was going to move seriously, and they were so frightened that they cowered in the city, and at the same time asked for help from the Lin Cong Tusi who lived in the guest wood.

Lin Chengxiang did not let them wait for the rescue of the soldiers, ten artillery pieces, concentrated on bombing the East City Gate.

After the city gate collapsed, more than 30,000 soldiers of the 20th Army poured into the city one after another, slaughtering 5,000 Tibetan soldiers in the city.

The Tibetan soldiers were gone, and what made Lin Chengxiang worried was that he captured 8,000 Tibetans in the city. Besides, they are marching and fighting, and it is useless to carry them, and they will consume food in vain, and in case of rebellion among Tibetans, they will have to divide troops to guard them.

In the places where Tibetans live, he had to be more careful.

The staff officer of the army built yì and handed these Tibetans to the care of the Han Chinese in Mangkang.

Lin Chengxiang agreed, but there were too many of the 8,000 Tibetans, and eating was also a problem. In the end, Lin Chengxiang killed all the old people over the age of 50, so that only 5,000 Tibetans remained, most of them women and children.

The Ming army escorted these Tibetans to Mangkang and temporarily served as slaves of the Han people, so that the Han people in Mangkang could also live a life of being a superior person.

On the way forward of the 20th Army, the defenders of Chaya and Jitang fled in despair and retreated to Kemu, which turned out to be Tulu Baihu's strategy, and he wanted to fight a decisive battle with the Ming army in Kemu, and the battle would be decided.

Lin Chengxiang got the message, not angry but happy, if a city is attacked, in these places surrounded by mountains and valleys, the Ming army will spend more time on the road than the siege time, now the Mongolian and Tibetan coalition forces are concentrated in Kemu, just can finish their work in a battle, if they win, Kemu can be flat.

What if it fails?

Lin Chengxiang didn't think about it, but the Ming army had a huge advantage in firearms, as long as he was not greedy for merit, there would definitely be no big defeat, and even if there was a partial defeat, it would not affect the overall situation.

Of course, Lin Chengxiang also knew that the final victory was still far away, originally there were 30,000 regular troops of the Mongolian and Tibetan coalition army in Kemu, which was comparable to the number of the twentieth army, plus the Ming army was an expedition, and there was no personnel supplement, and the Mongolian and Tibetan coalition army could recruit people into the army at any time, especially the Mongols, almost all of them were soldiers, and the newly recruited soldiers would not reduce their combat effectiveness.

If the Tibetans are religious and have the spirit of showing up for their religion, Lin Chengxiang estimates that the Mongolian and Tibetan coalition forces will count at least 50,000, unless they are defeated at the first blow, completely incapacitated to fight, and can no longer recruit civilians into the army.

Fighting on the opponent's territory, Lin Chengxiang had to be careful, and then he laughed himself, isn't this the Duogandusi of the Ming Dynasty? How did it become the other party's turf? At least nominally, they are still subordinate to the Ming Dynasty.

The northeast of Kemu is Damala Mountain, there is Nianqing Tanggula Mountain in the west, the southwest is Hengduan Mountain, the three mountains enclose a huge valley, this valley is relatively flat, the Nu River, the Lancang River, the Jinsha River pass through here, among which the Zhaqu River and the Angqu River merge into the Lancang River, and the Kemu is located at the confluence of the two rivers.

This is a rare open area and flat area on the plateau, and the Ming Dynasty established the government of the Duogandusi here, rather than the central area of the Duogandusi, probably because of the superior terrain here.

Lin Chengxiang camped fifteen miles away from Kemu, between the Lancang River and the Jinsha River, the terrain was relatively flat and open, and even if the Mongolian and Tibetan troops relied on the advantage of being familiar with the terrain, they could not sneak attack.

Sneak attacks were never the Mongols' strong suit, and strong attacks were their preferred option.

On the second day of Lin Chengxiang's camp, Tulu Baihu led 25,000 Mongolian and Tibetan troops to visit Lin Chengxiang.

The 25,000 combined army is already the limit of the Mongolian and Tibetan joint army, among the 25,000 soldiers, Lin Cong Tusi and Dewang Tusi each sent 5,000 Tibetan soldiers, and Tulu Baihu dispatched all his 15,000 Mongolian cavalry, because Tulu Baihu has the most soldiers, he naturally became the commander of the coalition army.

In the history of later generations, Tulu Baihu once unified Wu Sizang and was promoted to Gushi Khan, I don't know what will happen to his fate in this duel with Lin Chengxiang.

Lin Chengxiang arranged 6,000 gunners in the front, divided into three rows, nearly 10,000 cavalry guarded the two wings of the gunners, ten artillery, hidden a thousand steps behind the gunners, seeing that the Mongolian and Tibetan coalition forces were too numerous, he arranged 3,000 gunners at a place 80 steps behind the gunners, in case the front position was breached, with the protection of 3,000 gunners, the Chinese army would not be confused.

10,000 Mongol cavalry stood out from the coalition army, they relied on the speed advantage of the cavalry, and swooped down on the position of the Ming army, and the Mongols fought, never asking who the opponent was, nor asking about the strength of the opponent, their only magic weapon was to attack with all their might.

10,000 Mongol cavalry is not a tentative attack, according to Tulu Baihu's character, his 25,000 coalition troops should all attack and put on the battlefield at one time, but the Mongol soldiers are cavalry, and the Tibetan soldiers are infantry, and the two sides cannot synchronize, so he dispatched 10,000 cavalry.

Thousands of horses galloped, shaking the ground and shaking the hearts of the army, and the echoes stirred up by the banks of the Lancang River have drowned out the roar of the river slapping on the embankment.

The gunners of the Ming army, however, remained motionless, and the more frightened they were, the more prepared they had to be ready to shoot, and when their eyes were fixed on the horses' hooves, they forgot their fear for a while.

"Shoot." The heralds shouted loudly, and in the ears of the gunners, the shouts were deafening, completely muffling the "click" sound made by the horses as they galloped.

"Bang."

"Bang."

"Bang."

……

The first row of gunners began to shoot, because the soldiers were too nervous, the time to pull the trigger, there was a huge jet lag, the gunfire was chaotic, it was not a salvo at all.

However, the Mongol cavalry in front was too dense, and the effect of shooting was still about the same, and when the first row of gunners finished firing, the Mongol cavalry fell from their horses, more than 300 people.

When the third row of gunners fired, it was basically a salvo, and the rate of casualties of the Mongol cavalry gradually accelerated.

Two waves of shooting, the losses of the Mongol cavalry, have already exceeded two and a half thousand.

The cavalry was still on the offensive, and the gunners continued to shoot.

The gunners of the Ming army, each platoon of two thousand people, no matter how fast the Mongol cavalry were, could not compare to the bullets of the dense flintlock muskets, they were held back a hundred paces, and could no longer advance half a step.

It was not that they could not advance, the cavalry behind them were attacking without stopping, but as soon as they entered the line of death of a hundred paces, they could not advance any further, either falling off their horses or being dragged aimlessly by their wounded horses.

Because Tulubaihu was far away from the battlefield, he couldn't see the battle situation in front of him, he felt strange, obviously the cavalry was rushing towards the Ming army quickly, going forward and one after another, and there was no stagnation, why they didn't release their arrows, and they didn't see the Ming army retreat.
