Just when Yang Hongzhang moved the base camp to Datong to prepare for a big fight, Yanggao sent an urgent military intelligence, and a large number of Mongolian cavalry were found outside the side wall, about more than 10,000 people. This is also thanks to Yang Hongzhang's scout training and clairvoyance, so that he can discover the enemy situation at the first time.

Yang Hongzhang frowned, it is summer now, it is the time for horses to grow fat, why don't the Mongols go south instead of grazing, but no matter what the reason is, Yang Hongzhang did not dare to slack off, so he ordered all the cavalry to go to Yanggao to support overnight. As soon as the day dawned, Yang Hongzhang and others came to the south of Yanggao City, there were already scouts to report, it turned out that the Mongols moved faster than Yang Hongzhang and crossed the border wall and directly attacked the Yanhe checkpoint to which Yanggao belonged, and successfully broke through the checkpoint for the first time, the checkpoint casualties were more than 200 sergeants, fortunately, most of the goods have been transferred to Yanggao City, and almost all the three checkpoints in Yanggao were destroyed in one night. However, the Mongols did not gain much, so they are now in the city.

Hearing this, Yang Hongzhang smiled, where is this to attack the city, it is obvious that the dog jumped over the wall in a hurry, and he cut off the financial route of the Shanxi merchants and the food of the Mongols and Manchus at the same time.

"Ordered Sun Fei to quickly assemble troops to bypass the battlefield and go to the border wall to block the retreat of the Mongols. He ordered the Rokh to relax his guard and draw the Mongols outside the northern walls for at least an hour. Yang Hongzhang gave the first order to the herald beside him, and Xia Dongwei and Yang Sheng were already eager to try, under Liu Haiming's needle lead, Yanggao and the horse thieves near Tianzhen were all Zhao'an, and now Xia Dongwei's cavalry battalion has three thousand, and all the elite battalion soldiers who returned to Datong have been temporarily incorporated into the pro-soldier camp. Therefore, the cavalry led by the two of them was as large as 4,500 people, and it was no wonder that they were not excited in the face of the 10,000 Mongol cavalry that came to attack.

"Yang Sheng will attack from the west with his commander to lure the enemy, and only after the enemy's cavalry has turned will you be allowed to charge from the east!" Yang Hongzhang instructed Xia Dongwei, this is now more and more Lu Xiangsheng's demeanor, Yang Sheng, who is a martial artist, is not an opponent at all, plus there are more than 100 elite cavalry of Lu Xiangsheng's heavenly army as a team, but it looks good.

The north gate of Yanggao, the newly built city wall cruelly blocked the progress of the Mongols, and the Mongols did not seem to have imagined that the new Datong general army would set the general army yamen in Yanggao, and then build a new city wall that had been completely destroyed in just a few months. However, they got the news that the brave and warlike general army went to Datong, and looked at the banner on the city wall, which was clearly a Luo, which meant that it was similar to the information provided by the southerners, and it should be the Luo enemy of the infantry battalion defending the city.

Originally, the Mongols were reluctant to attack the city after seeing the construction of the city wall, but this time they attacked three checkpoints, except for killing a lot of Ming soldiers, almost nothing, if the army was withdrawn, then the Ming people could restore the checkpoints in a day's work.

If the Southerners' intelligence is accurate, and there are only 2,000 defenders in the city, but there are enough food for 10,000 people to eat for several months, then it is worth paying some price. Therefore, after careful discussion, they decided to attack the city for one day, and if they couldn't capture Yanggao in one day, they would go to Tianzhen County to destroy other checkpoints, and then find an opportunity to attack Tianzhen County.

Luo Kedi was originally full of confidence, looking at the Mongolian cavalry outside the city, all of them were meritorious in his eyes, if he could take down thousands of Mongolian heads before the arrival of the commander, his status in the Yang family army would also rise. So when the Mongols came outside the city, he divided the team into three groups, 3,000 infantry and 1,500 men each, who took turns to go up the wall.

Since 1,500 of the 1,500 men on the city wall had flintlock pistols and 500 were archers, the Mongols suffered heavy losses in the first few assaults, which also made the Mongols begin to consider whether to continue the siege, because the experience of dealing with the Ming army over the years told them that the Ming army was good at defense, especially defending the city.

But soon the commander gave the order, and he shook his head and removed the men on the city wall five hundred. And ask everyone to slow down the counterattack.

The changes on the city wall soon attracted the attention of the Mongols, and the four Mongol tribal leaders standing in the rear began to discuss, they did not understand why the Ming army suddenly became like this, could it be that the stockpile of gunpowder and arrows in the city was not enough? But whatever the reason, such a rare opportunity must not be missed, and almost all the tribal leaders made a decision at the same time.

Soon they found out the real reason, because a strange army in the west of Yanggao City was galloping forward, although the number was not large, but there was a Yang character on it, according to intelligence, in addition to Yang Hongzhang, the general army of Datong Town was left with only one Yang Sheng. And Yang Sheng is Yang Hongzhang's pro-military battalion officer, but this team seems to be arranged relatively widely, not all the cavalry are gathered here, so all the Mongolian leaders saw this banner and their eyes lit up, and immediately ordered the cavalry that was besieging the city to gather back, and the cavalry team of more than 10,000 people quickly turned around, assembled, and then began to charge.

Bang bang bang, bang, just when the two teams were getting closer and closer, and the Mongols were ready to completely surround this cavalry after seeing the reality of Yang Hongzhang's team clearly, the flintlock pistol rang out, and on the transverse plane up to one hundred and fifty paces wide, the dense flintlock pistols were round after round, and after five rounds of flintlock muskets, the Mongolian cavalry charged the team completely chaotic, and some of the cavalry who were lucky enough not to be hit by the flintlock pistol quickly dispersed in an attempt to take advantage of the numerical advantage to surround from the flanks, while some who were not afraid of death continued to charge at the rain of bullets, Waiting for them is a newly made palm thunder.

The Mongols lost three or four hundred men in the first charge, but this did not prevent the cavalry of tens of thousands from continuing to charge, and those clever cavalry had quickly dispersed and approached from both flanks, but soon the rear of the entire Mongol army was in chaos, because there was a sound of horses' hooves from behind, and the cavalry instinctively knew that there were many people. And most of their leaders watched the battle in the rear with their own soldiers, so some of them were anxious to turn their horses back to protect the leader, while some of them continued to advance, causing a certain amount of confusion in the middle and late sections, but these people were obviously well-trained, and they quickly adjusted their ranks before the cavalry in the rear arrived on the battlefield, and about two-thirds of the cavalry began to turn their direction to the east.

It's just that the two sides haven't made contact yet, the north gate of Yanggao County opened, and a group of infantry rushed out from inside, and the infantry did not immediately attack the Mongolian cavalry after coming out, but quickly dispersed, and as the number of people increased, the Mongols soon found that this was the battle formation that the Ming people were best at, but despite this, they still did not take these infantry into account, because the most awesome infantry battle formation was defense rather than charge.

It's just that the leaders of these Mongol tribes miscalculated the situation, because after all the infantry of 3,000 people came outside the city, they immediately spread out, and put out the Gustav phalanx, although there were not too many flintlock muskets, but the glittering spears that had just been equipped quickly made the Mongols taste the bitterness, and when they fought the east and west sides, the middle section of the Mongols was quickly chiseled, and even the leader of a tribe was directly dismounted in the wheel army.

After the infantry phalanx of 3,000 men penetrated through the middle, Xu Su turned around and headed west, preparing to besiege five or six thousand cavalry with the cavalry from the west.

Originally, in terms of individual combat ability, the Mongolian cavalry was not inferior to the cavalry of the Yang family's army, but the cavalry of the Yang family's army could not stand up to the muskets and palm mines. However, the Mongols did not have the determination to die, and in the past, as long as they had the advantage in numbers, it was basically very easy to fight against the Ming army.

Therefore, when the war horse was frightened by the palm thunder, most of the people were not mentally prepared at all, although they were numerous, but there was no such strict management system as the Ming army, and they were often scattered by one person, and everyone was scattered.

The first to be defeated was the western half of the cavalry after being cut by the infantry, they had no advantage in numbers, and Yang Hongzhang's pro-military battalion was the best in the whole army in terms of equipment and personnel quality, so they suffered a big loss in the case of a hard encounter.

After paying the price of nearly a thousand men, the Mongol tribes began to retreat, and after the troops in the west retreated, the troops in the east faced three blows, and they had no intention of fighting, and they all turned around and fled the way they came.

Once again, however, they miscalculated the situation, for they were confronted by a Ming army of nearly four thousand five hundred cavalry, and those with flintlock muskets were naturally at the vanguard of the pursuing force, and the firing of flintlock muskets from two hundred paces away made the Mongols tremble again.

When these panicked Mongol cavalry fled to the gap in the side wall, they were greeted by infantry of the same size as Yanggao City, and they were setting up in that strange formation.

Seeing that the pursuers were getting closer and closer, several leaders no longer hid their secrets, but launched a charge against Sun Fei's infantry phalanx, but unlike the Jurchens' super cavalry and archery skills, the Mongols seemed to prefer close combat, which was the source of their heavy price. When the swaying spears pierced rhythmically, the Mongol cavalry was almost pierced with men and horses, and then fell to the ground as an obstacle to the rushing cavalry, and then the archers hidden in the phalanx fired at close range, and the charging team was instantly chaotic.

Seeing that the Ming army occupied the right time and place, the Mongols, who were originally disunited and just came to retaliate to find an opportunity, suddenly scattered and began to flee in all directions with the tribe as a unit.

In this regard, Yang Hongzhang did not give the order to chase and fight, but let the cavalry battalion follow the larger one of them, and the rest of the people gathered their troops to let people count the results.

Although it looks beautiful, the price paid by the Ming army is not small, the pro-soldier battalion lost more than 200 people, Xia Dongwei's cavalry battalion lost more than 400, and the infantry battalion plus the previous defensive battle also lost more than 300. Combined with the loss of several checkpoints, this time the Mongol sneak attack caused at least more than one and a half thousand casualties.
