Under the hill in the middle of the battlefield, Zuo Liangyu led a 6,000-strong chariot and cavalry brigade to set up a hollow phalanx with a radius of two miles, and then entangled with the two thousand-man teams sent by the Mongols.

Whether it was Zuo Liangyu or the two Mongolian thousand-man teams who were constantly testing outside the car formation, they all knew very well in their hearts that it was not the battle between them that would determine the outcome of this war.

Therefore, the two sides maintained a tacit understanding from the beginning, whether it was the Mongol attack or the defense of the Ming army, it was not very intense.

After the arrangement of the hollow car formation was completed, Zuo Liangyu had actually put most of his mind on the defense of the hill south of the car array.

The cavalry on the flat ground could not break through the defense of the chariot formation without paying heavy casualties. After all, since the creation of the cavalry battalion by the Ming army, this tactic specially used to deal with the Mongolian cavalry on the steppe has been verified many times.

As long as these Mongols' brains are not broken, they will not close their eyes and rush hard. However, if these Mongols broke through the defense of the friendly troops on the hill, and then attacked the car formation from top to bottom, it was a flaw that made Zuo Liangyu restless.

In fact, Zuo Liangyu did not agree with the battle plan formulated by the staff of the base camp, and he thought that this battle plan was too risky.

If his left flank can't defeat the right flank of the Chahars, or if his own army doesn't hold the small hill behind him, the elite soldiers of the Ming Xuanfu and Datong will all fold on this grassland.

Then after this battle, the Datong border pass is like a fictitious, and it can no longer stop the Chahar Department from going south to enter the pass.

According to Zuo Liangyu's opinion, the Ming army should retreat to the Great Wall, and then spend time with the Chahar Department until it snows, and Lin Dan Khan has to withdraw his troops.

The most disgusting thing about this battle plan is that the chariot formation is an excellent thing to defend against cavalry on the grassland. But once it was set up, if the Mongol cavalry could not be defeated, or if they took the initiative to retreat, it would be difficult for the Ming army in the chariot formation to retreat in front of the enemy cavalry.

Zuo Liangyu was worried about whether the friendly troops on the hill behind him could hold their positions. For a while, he was worried about whether Cao Wenzhao could defeat the right wing of the Mongols. He didn't believe in his heart that those gorgeously dressed Beijing cavalry could make any limelight in this war.

However, his worries were finally relieved a lot when he saw the pillar of smoke rising from the direction of the rear camp of the Mongolian right wing.

Standing on the high platform on the east side of the hollow car formation, Zuo Liangyu, who had been observing the battle situation in the north, put down the binoculars in his hand, and issued several orders to the adjutant below, asking the soldiers in the car formation to prepare to meet the enemy.

The high platform at his feet is a command platform cobbled together by two cars, which not only allows him to climb high and look far, but also commands the troops with flags on it, the only drawback is that the place is smaller.

Zuo Liangyu was thinking about whether to make a suggestion after the end of this war and let the Ordnance Superintendent improve this kind of vehicle.

However, he was soon frightened by the torrent of cavalry sweeping from the north, and he saw the charge of tens of thousands of cavalry for the first time. In front of cavalry of this size, it is estimated that only the tall masonry wall can stop it.

But now, in front of these cavalry, there was only a thin side van. Zuo Liangyu suddenly realized that he seemed to have underestimated the power of a cavalry charge of this scale, and the defense line he had set up was still a little thin.

If he can't hold the car formation, then let alone win this war, it is still a question whether he can return to the pass alive.

After realizing this, Zuo Liangyu subconsciously glanced around the car array, and then nervously gave the order: "Move the side car on this side of the hill to the middle, from east to west, and set up three more small formations in the car array..."

Although the Ming soldiers in the car formation could not see the scale of the cavalry in the north, the vibration from the ground had already made these soldiers react quickly.

Although their faces were a little pale, they still quickly pushed the carts facing the hill side to the middle of the cart array, reconnected them, and formed three small cart formations side by side.

Zuo Liangyu's judgment is indeed good, for those Mongolian cavalry who were driven south by the Ming cavalry and could no longer stop, a thin defense line of partial vans was indeed unstoppable.

The Che Cavalry Battalion under Zuo Liangyu still uses the traditional firearms of the Ming Army, most of which are less powerful and have a range of 10 or 20 steps.

When the Mongols paid hundreds of casualties, they directly broke a side van. The 1,500 Ming troops behind this line of defense, having lost more than 300 men, had to abandon their own line.

And the Mongolian cavalry that broke through the car formation was obviously a great threat to the Ming army that had no cover on the flat ground.

If it weren't for Zuo Liangyu with a team of cavalry to personally break the rear, it is estimated that the Ming army before the second line of defense temporarily constructed would probably be wiped out.

Even so, the Ming army, which retreated to three small car formations, had less than 5,000 men left, and the losses of the Mongol cavalry were about a thousand.

The only thing that made Zuo Liangyu happy was that although these Mongolian cavalry broke through the first line of defense of the car formation, their speed finally slowed down. The cars on the first line of defense, although they could not block the onslaught of the Mongol cavalry, became an obstacle to the charge of the Mongol cavalry.

But even so, Zuo Liangyu, who had broken off for his subordinates, almost fell into the capture of the Mongolian cavalry who broke into the car formation.

Fortunately, two Ming soldiers recklessly ignited the two barrels that had not had time to be carried to the second line of defense*.

The power of these two barrels* is really amazing, there are few survivors within a radius of 10 meters from the detonation area, and the Ming army and Mongolian cavalry closest to the center of the explosion have been blown to the bones.

In the area 10 meters away, many horses were frightened and went crazy, which immediately interrupted the rhythm of the Mongol attack. Zuo Liangyu took advantage of this opportunity and retreated into the second line of defense with the personal guards who had lost a small half.

When the Mongols organized an attack again, the Ming army, which was already a little panicked, finally relied on three small chariot formations to support each other and stabilized.

Zuo Liangyu, who organized the soldiers to resist, found that when these Mongolian cavalry were huddled together and lost their impact, they immediately became the target of their own firearms.

Only then did he regret that he should have equipped his soldiers with more arquebuses developed by the Ordnance Superintendent. In this environment, the arquebus, which had a better range and power, was more effective than the old firearms in the hands of the soldiers in his battalion.

Although these old firearms are fast and loud, as long as they do not hit the key parts of the target, the opponent can still continue to fight.

The same was true for the arquebuses, which were slow to reload, and the Mongol cavalry that was hit immediately became incapacitated. In particular, large arquebuses that require the use of brackets can be used to defeat everyone and horses with a single shot, which can be described as very powerful.

However, because his soldiers were reluctant to replace the arquebus, this armory was produced by the arquebus. After all, the weapons made in the capital workshop have a bad reputation in the army, and no one wants to go to the battlefield with a musket that does not know when it will explode.

And these soldiers have become accustomed to the weapons they use, although they are less powerful, but they are easy to use. It was under their opposition that Zuo Liangyu selected a few teams of newly recruited battalion leaders to be equipped with arquebuses produced by the Ordnance Supervisor.

Now on the battlefield, he realized how stupid he was to accommodate these subordinates, and while he stubbornly organized the men and horses to stabilize the front, he asked Mao Yuanyi on the hill behind him for support.

When the troops of the Mongolian right flank were driven south by the men and horses of his own left flank, Mao Yuanyi had already noticed this scene.

After repelling several Mongol attacks, he handed over the eastern line to a staff officer at his side, and himself presided over the construction of the artillery fort on the north side of the hill on the downhill slope.

Unlike the 4 Furlong cannons under 1,000 catties in the east defense, the 8 forts on the north side are all heavy Furlong cannons with more than 1,000 catties.

The maximum firing range of these guns was up to 1,500 meters, the effective range was between 600-1000 meters, the shell weighed 4 catties and 2 taels, and the charge was 1 catty and 4 taels.

Because these artillery pieces were heavier, it was particularly difficult to move them to the hill and arrange them, so when those Mongolian cavalry attacked Zuo Liangyu's car formation, Mao Yuanyi had not completely arranged these artillery.

However, when Zuo Liangyu withdrew his troops to the rear of the small car formation, four artillery pieces were finally placed on the battery block.

After receiving Zuo Liangyu's request for help, Mao Yuanyi asked the officer in charge of artillery firing to support the cavalry battalion at the bottom of the hillside.

Although the war between the Mongols and the Ming army has been entangled for more than 200 years, the firearms of the Ming army have long been no stranger. After all, the Chahar Department has migrated to the Liaohetao Plain in eastern Liaodong for nearly a hundred years, and they may not be unfamiliar with the three-eyed guns used by the Ming army, but they are not very impressed by the heavy Furlong machine guns.

They never thought that these Ming people would carry the Fran cannons placed on the fortress to the grassland, so when they were attacked by the artillery for the first time, these Mongolian cavalry were still stunned to look at the black shadows flying from the sky, and did not make a dodging move.

Because these Mongol cavalry were driven away by the Ming army, they had to huddle together in a dense formation and move south, and broke through Zuo Liangyu's chariot formation. But their formation is simply the best target for artillery.

Each shell plowed a river of blood through the dense crowd, and severed limbs and legs fell on both sides of the river. With the continuous firing of the 8 artillery pieces on the mountain, Zuo Liangyu's defensive front suddenly turned from danger to safety.

These Mongol cavalry no longer had the will to continue attacking the Ming line, and began to scurry in front of the Ming line like a headless fly, only wanting to escape from the area of artillery fire.

The confusion of these Mongolian cavalry suddenly made Wu Huai, who was driving them in the rear, see an opportunity, and he immediately asked his subordinates around him to shout, those who dismount and abandon their weapons will live, and those who stubbornly resist will die.

The Mongolian right-wing cavalry, which had suffered successive blows, finally began to surrender a handful of people in a situation where no one was in charge of the overall situation.

When Mao Yuanyi ordered the shelling to stop, more than half of the nearly 10,000 cavalry at the foot of the mountain had already dismounted and surrendered, and there were thousands of Mongolian cavalry, although the formation was not disordered, but they were squeezed into a very small area by their own troops, and it could be said that they could not move.

The commanders of these cavalry sent messengers to the Ming army, indicating that they were willing to surrender, but hoped to be given preferential treatment.

The most helpless were Gui Yingcha and others, who were blocked in the encirclement of the Ming army by their own men and horses, and they couldn't escape, so they were surrounded by Cao Wenzhao and his team.

Gui Yingcha was reluctant to surrender, and several times he wanted to commit suicide, but was stopped by his cronies. Cao Wenzhao sent people to surround this group of Mongols, and at the same time sent people to assist Wu Huai in collecting and surrendering the Mongols.

Although they fought again and again, Cao Wenzhao and the cavalry of the Ganming army felt extremely excited, and this battlefield was almost over. The rest is only a question of how much benefit the Ming army can get.
