The engagement between the Ming-Mongol coalition and the Chahar army first began on the battlefield in the south. Compared with the caution between the Ming army and Lin Dan Khan, the allied forces of the Mongol right wing became extremely excited from the beginning of the war.

When the grassland station was just seized by Lin Dan Khan, both the Tumut Department and the Tushet Department were in a panicked situation.

The tribal leaders at the top naturally hated Lin Dan Khan, but the herdsmen at the middle and lower levels were in a state of chaos.

Traditionally, they were expected to be subservient to the Mongol Great Khan, who was born into the Golden Family, but the herdsmen, whose homes had been destroyed by Lin Dan Khan, could not continue to identify emotionally with the Mongol co-ruler.

With the aid of the Ming Dynasty and the propaganda of the lamas from the Ming state, the actions of the right-wing Mongol tribes and the Ming army were recognized as preventing fratricidal warfare among the Mongols, rather than opposing the Golden Family bloodline as a tradition of the Mongol Great Khan.

So that these chaotic middle and lower class herdsmen finally found a reason to wave their knives at the Mongol Great Khan. Maybe this reason is very reluctant, but it is enough to anesthetize these tribal warriors to fight this war.

Therefore, at the beginning of the war, the allied forces of the Mongol divisions on the right flank dispatched 5 thousand troops, and on the battlefield nearly 20 miles wide, this number of cavalry was just enough to cover the entire front of the battlefield.

In response to the rash actions of the right-wing Mongolian tribes, Gonchuktaiji also had to respond, and also sent a thousand-man team composed of five right-wing Mongolian tribes to step forward to block the opponent's attack.

The allied forces of the right-wing Mongolian tribes, which had been violently pressing, suddenly hesitated to slow down the pace of their attack after coming into contact with the opposing army.

Because they had already recognized that there were quite a few familiar faces in the army opposite. Originally, their high morale suddenly dropped suddenly.

The weapons held high in their hands were also lowered a little weakly. Similarly, an army of right-wing Mongol tribes had little interest in fighting against brothers and relatives who were originally of the same clan.

The two troops, from a menacing charge against each other at the beginning, quickly turned into a melee that circled and chased each other.

Except for the riverside area, most of this grassland belongs to semi-arid grasslands, although there are various pastures as tall as no man's calf, but under the trampling back and forth of tens of thousands of cavalry, it will soon become dusty, and it is difficult to distinguish the formation between the enemy and the enemy.

At this point, the commanders-in-chief of both sides have lost the ability to command these troops, and they are unable to intervene effectively, so they can only wait for these forces to decide the winner or loser.

As a result, the battlefield on the South Road, which was the first to engage in battle, became the most perfunctory place of battle between the two sides.

On the side of the coalition center, when they stopped, they were already very close to the small hill in the middle.

When the troops were reorganized, Mao Yuanyi led a battalion of infantry to seize the top of the hill, while Zuo Liangyu took two battalions of chariots to ride the camp and set up a hollow chariot formation of 6,000 people on the north side of the hill.

This kind of combat method of placing the partial van on the periphery as the city wall and the firearms guarding the formation is the best combat method for the grassland tribes as proved by the lives of countless Ming soldiers.

Lin Dan Khan naturally understood the benefits and disadvantages of this tactic, because the combat method of the Later Jin State against him was basically born from the tactics of the Ming army, but the troops of the Later Jin did not have so many vans, and the tactics of the Jurchen cavalry and infantry were sharper.

He sent 4 thousand-man teams, three thousand-man teams to suppress the hollow car formation of the Ming army on the periphery, while another thousand-man team captured the small hill in the middle of the battlefield.

After Lin Dan Khan tried to seize that hill, he condescendingly attacked the interior of the chariot array, which led to the collapse of the Ming army's chariot array.

In his memory, although the Ming army had many equipment, the quality was uneven, and the soldiers lacked tenacious combat courage, and once they were in a disadvantageous position, they would often collapse inexplicably.

Therefore, he was very sure that when his army occupied that small hill, the Ming army chariot array below the hill would fall into chaos. Although the Ming army's chariot formation was well defended, it was difficult to move once it was deployed.

It is certainly difficult to win by using cavalry against the chariot formation, but if the Ming army itself comes out of this tortoiseshell-like chariot formation, this kind of expensive chariot formation will become useless.

Lin Dan Khan's plan was not bad, but his subordinates ran into trouble when they carried out his orders. Although this small hill is not difficult, it looks more like an earthen platform made of earth.

However, the flank of Tutaizi was firmly protected by the hollow car formation of the Ming army below, and the southern side was too steep, so Lin Dan Khan's troops could only attack the front of the hill about 2 miles wide.

There were no big trees on the hill, but there were bushes more than half a man high, and in the bushes there were several paths for a horse, but there were no passages for a large number of people to go immediately.

Almost at the same time that a handful of horsemen in this thousand-man team climbed to the top of the hill, the forward troops of the Ming army also climbed to the top of the mountain.

Unlike the unprepared Chahar Division, the Ming army not only made a detailed reconnaissance of this hill a long time ago, but also built three passages on the western slope that could accommodate four horses in parallel.

It's just that after the Ming army repaired these three passages, they put the felled shrubs back on the passages, and it seems that this hillside seems to be nothing unusual from a distance. In the previous outpost war, the Ming army protected this area to the death and did not let the sentinels of the Chahar Department approach, so the Mongols of the Chahar Department did not know about this situation.

When the Chahar Division, a group of riders with the best riding skills in a thousand-man team, rushed to the top of the hill along the winding path in the east, it was a squad that the Ming army climbed to the top of the mountain.

Several cavalrymen, who had lost their speed, were soon driven down the hill by the outnumbered Ming spearmen. When the number of Ming troops climbing to the top of the mountain increased, and several passages up the mountain were also blocked, the Mongolian nobles who led this thousand-man team finally gave up the combat method of directly attacking the top of the mountain.

He then ordered the three hundred-man team to dismount and clear the bushes, while the others in turn prepared for the assault. In the eyes of this Mongolian nobleman, as long as a few passages up the mountain were cleared, a few spears could not stop the continuous charge of the cavalry under his command, and as long as they could break through the defense line of the Ming army, these Ming troops could no longer stop his thousand-man team.

The commander named Izbis had a good idea, but the only thing he was wrong about was that his men didn't think about going into battle to do the work of felling.

The three hundred-man soldiers, with a distressed look on their faces, took the weapon they loved like their lives in the past to cut down the bushes, and this speed was naturally very slow.

While they were cutting down and clearing the shrubs, the Ming army, which occupied the top of the hill, also began to build fortifications. Compared with the Mongols under the mountain, these Ming soldiers were organized and much more prepared.

Some soldiers, armed with special machetes, cut down the protruding bushes on the top of the mountain one by one, and cleared the top of the mountain into a blank area within a radius of about 2 miles.

These shrubs were carefully placed to the east and northeast to form a half-man-high barrier that sheltered the hill from the ground.

After blocking the view of the Mongols, Mao Yuanyi began to command the Ming army to dig the soil on the periphery of the mountain, digging a trench around the top of the mountain, about one meter wide and half a meter deep.

The excavated soil was packed in prepared sacks, and a second line of defense was formed along the dug trenches. The sacks were laid parallel to the trench and were arranged in a double staggered manner, with the gap in the middle filled with earth.

These low walls, made of sacks filled with soil, were no more than a meter high, but together with the outer moats, the Mongols had lost the height advantage of riding horses.

By the time Iribis's thousand-strong army cleared the perimeter of the hilltop and piled up the barrier with cut bushes, the trenches and defensive lines to the north of the Ming army were already complete.

When Mao Yuanyi noticed that the Mongols were beginning to clear the bush barrier they had erected, he ordered 10 spear teams to enter the trench in front of the improvised earthen wall according to the reserved entrances and exits, and archers and musketeers stood behind the earthen wall to meet the enemy.

After entering the trench, a team of 50 spearmen entered the trench, they crouched down, raised the spear diagonally forward 45 degrees, and held the spear tightly with both hands, so that the root of the spear was propped up on the side wall of the trench behind him.

500 spearmen could not block nearly a kilometer of frontal defense, but it was enough to block the passage up the hill cleared by the Mongols, and on either side of each spearman, a number of rattan soldiers were arranged to guard the flanks.

When the Mongol thousand-man detachment was roped away from the last shrub barrier leading to the top of the hill, one saw such a well-defended fortification.

The first group of Mongol cavalry to rush up the hill did not even have time to warn the rear, and with the cooperation of the spearmen and musketeers of the Ming army, they had already suffered all casualties.

It wasn't until he filled in the 3 centurians that he realized something was wrong. He only heard the screams of his own people, and could hardly hear the screams of the Ming army, and the frequency of the Ming army's firearms was too high.

When Iribis sensed that something was wrong and stopped attacking, Mao Yuanyi was standing on the earthen platform built in the middle of the hill, observing the battle on the front defensive line.

Before the smoke of * did not cover the entire defense line, Mao Yuanyi suddenly found that the effect of these two simple defense lines was surprisingly good.

One cavalryman could deal with five or six infantry on flat ground, but in this terrain, he had already killed hundreds of Mongol cavalry with only half an infantry battalion.

Due to the restrictions of the terrain, the Mongolian cavalry in front could not rush through the Ming army's defense line, and because the retreat route in the rear was blocked, they could only be beaten in vain in front of the Ming army's position.

By the time the Mongol generals below the mountain gave the order to retreat, the Mongol cavalry had already left the corpses of more than 200 cavalrymen in front of the Ming army's position, and the Ming army only had two spearmen who were wounded by the weapons thrown by the desperate Mongol cavalry.

When the Mongols retreated, a sentry officer came to Mao Yuanyi to ask what to do with the corpses and wounded Mongols in front of the position.

Mao Yuanyi was still thinking about it, and a staff officer of the staff department standing beside him had already suggested: "My lord, we need the bodies of these people to record their mortal wounds, and to judge which weapons the infantry battalion is equipped with, which ones are the most suitable." ”

"We don't have that many people right now." The sentinel who presided over the defense line immediately replied angrily.

"You can ask the people of the baggage camp to help, anyway, if the Mongols want to launch the next attack, it will take a while. Besides, you don't want your front line to be full of corpses, it will obstruct your view. The staff officer said sensitively.

Mao Yuanyi stopped the quarrel between the two and said: "Move them from the front to the rear first, just replace half of them and go down the defense line to rest."

Let the men of the baggage battalion assist the artillery regiment in carrying the artillery, and when they go down, they can just take the corpses and the wounded with them. As for you, after Cao Yun came up with the artillery regiment, he assisted them in building the artillery fortification, and we don't have any extra time to waste..."
