On March 15 of the second year of Chongzhen of the Ming Dynasty (1629 AD), Sun Chengzong's Liaodong Army entered Ningyuan, and then stationed in Jinzhou and Guangning.

Since the new First Army was already stationed in Guangning, Shanhaiguan, Ningyuan, and Jinzhou, which were already in the rear of the Ming army, only 10,000 Liaodong troops were stationed in each of them, and 30,000 Liaodong troops were stationed in Guangning, and another 20,000 Liaodong troops were building a cement road from Jinzhou to Guangning, extending the first avenue from Beijing to Shanhaiguan to Guangning.

There are also 20,000 Liaodong Army, which served as an auxiliary army for the Northern Expedition, specializing in transporting grain and grass materials, and the Beijing Division sent the supplies of the Northern Expeditionary Army to the Three Customs, while the 20,000 Liaodong Army took over from Shanhaiguan and transported the supplies to Guangning, which became the material transit station of the Northern Expeditionary Army.

On 20 March, the 100,000 First Army, assembled in Quang Ninh, officially marched eastward and began the Northern Expedition to Jiannu.

In the vast land east of Guangning to the Sancha River, there were originally stragglers with red flags, white flags, white flags and blue flags, but after Mang Gurtai was transferred back to Shengjing by Huang Taiji, the stragglers of each banner also returned to Shengjing, and it was the white flag of Dolgon who confronted the Ming Dynasty here.

Zhengbai Banner has a total of 28 full Niulu and 8,400 soldiers, but Dolgon's defense area is mainly east of the Sancha River, from Liaoyang to Gaizhou.

To the west of the Sancha River, there are only two strongholds, Xiping Fort and Sancha River Fort.

Although Dolgon participated in the peace talks with the Ming Dynasty, he was ready to do both when he arrived at the Liaodong front.

If Da Ming and Da Jin can really sign a peace treaty, he will stick to Xiping Fort and Sancha River Fort, and then move; If the Ming Dynasty and Dajin cannot reach a peace treaty, with the current situation of the Ming Dynasty, Dajin and the Ming Dynasty will inevitably have a large-scale war, and Xiping Fort and Sanchahe Fort are the first line of defense to block the Ming army.

Regardless of whether the peace treaty was signed or not, the Xiping Fort and the Sancha River Fort west of the Sancha River were strategic points for Dolgon.

However, Dolgon's soldiers were too few, and the defensive area was too vast, so Xiping Fort and Sanchahe Fort could only be stationed in four Niu Lu each, and in addition, Dolgon had already made contact with the Blue Flag Banner Lord Zilharang, who was stationed near the Yalu River, and once the battle situation changed, the two sides would respond to each other.

Relying on the huge numerical superiority and flintlock superiority, the Ming army had extended its strength to the east of Quang Ninh, and the rangers were also showing off their might on the open grassland.

Near Xiping Fort, a small group of Ming army rangers may be seen at any time, and the Jurchen rangers can only cower in Xiping Fort, once they go out, they will inevitably be besieged by Ming army rangers.

After Dolgon came to Liaoyang, he once sent an envoy to Yuan Chonghuan as an envoy to the peace talks, hoping that the rangers on both sides could live in harmony.

Yuan Chonghuan replied very simply, take the peace treaty, as long as the peace treaty is seen, the Ming army will not expel the rangers of the Dajin Kingdom.

The peace treaty has not yet finally taken effect, and Dolgon has nothing to do, he thinks that Yuan Chonghuan is so aggressive, it must be that Daming hopes to sign a peace treaty with Dajin as soon as possible.

However, the two sides were not in a state of war, but a temporary tacit peace, and when Dolgon delivered supplies to Xipingbao, the Ming army was never upset.

Yu Chongxiao's Third Army, which served as the vanguard of the Middle Route Army of the Northern Expeditionary Army, had never participated in the battle of recovering the three cities of Liaodong in the first year of Chongzhen, and Yuan Chonghuan hoped that the Third Army would have the opportunity to train.

After Yuan Chonghuan briefly explained a few words to Yu Chongxiao, he ordered the Third Army to attack Xiping Fort, and be sure to annihilate the defenders of Xiping Fort, and follow Zhu Youzhen for a long time, Yuan Chonghuan also knew that the number of Jurchens was limited, and their vitality would definitely be consumed.

At noon on this day, a Jurchen transport team, escorting a batch of supplies, was about to enter Xiping Fort, when it was interrogated by the Ming army rangers, and the two sides were entangled.

The Ming army rangers released fireworks, and a large number of Ming troops hidden nearby quickly arrived at the scene, and they brought people and goods to capture all the Jurchens, although the Jurchens repeatedly explained, but the Ming army did not understand his language at all.

At the second watch, the Jurchen convoy appeared at the east gate of Xiping Fort.

"Open the door, open the door, the supplies we transported have arrived." The leader of the convoy shouted loudly at the head of the city in Jurchen words.

"Convoys? Why did you arrive at night? We're all running out of cooking. The defenders at the head of the city were overjoyed.

"Do you think I'm willing to brave the darkness? If I didn't know that you were short on food...... Quickly open the city gate, Lao Tzu hurried overnight, so tired that his whole body was about to fall apart. The leader cursed.

"Wait." The defenders threw the torches in their hands from the city, and by the light of the fire, they saw that the convoy was wearing the leather armor of the Dajin Kingdom, and then they were relieved.

"What? I almost threw it on Lao Tzu's head. The leader was a little angry, "Could it be that there is a sneak attack by the Ming army?" You stupid ass! ”

"I'm sorry, I'm sorry." The defenders apologized repeatedly, for fear that the transport team would be angry and transport the grain and grass away, "This is the old rule, and I can't help it." ”

"See it clearly now? If the city is not opened, Lao Tzu will transport the grain grassland road back. The leader put out the torches, and there was darkness beneath the city.

"It's on, it's on." The defenders agreed one after another, "Open the city gate and welcome the grain and grass into the city." ”

The gates were opened, and the defenders waited in the gates.

The grain and grass cart came in, and the leader of the transport team walked in the front, and he laughed at the defenders twice, "Just a few of you defending the city?" ”

"It's not a time of war, and you don't need too many soldiers defending the city."

"Also, now you don't need to make all the grass and trees," the leader looked around, and couldn't see anything clearly in the dark, "This Ming grain truck is really easy to use, if you rely on war horses to transport, these grain and grass will need at least five hundred war horses." ”

"That's, that's, Daming's things are just easy to use, but unfortunately, we can't make them."

"You don't have to make it." Before the leader's words could be heard, he raised his sword and cut down the soldier.

The rest of the defenders, before they could figure out what was happening, were also slashed by the other transporters at the entrance of the city gate.

The leader made a gesture: "Quick, seize the city gate to prevent Jiannu from counterattacking, Ah Si, move the transport car away, Xiao Lei, set off fireworks." ”

At the same time as the transport vehicle was dragged upside down from the city gate hole, a blue fireworks rose high at the east gate of Xiping Fort.

Du Tong, the commander of the Seventh Division of the Third Army, who was lurking in the shadows, had been waiting for the fireworks to appear, and when the blue fireworks appeared in the sky, he got up from the grass with a bone, "Hurry up and get on the horse, they have succeeded." ”

"Da Da Da ......"

The sound of the horse's hooves hitting the ground violently could be heard far away in the quiet of the night, and perhaps with the shaking of the ground, the Jurchens in the barracks were also alarmed.

But they didn't understand what was happening, and they didn't know where the voice was coming from, so they hesitated for a moment.

It was at this short moment that the Ming army seized the opportunity.

The Seventh Division threw the horses outside the city, took advantage of the night, and rushed into the east gate on foot, Du Tong followed the front army to the city, "Quick, occupy the city and establish a defensive formation." ”

The soldiers who entered the city in advance immediately besieged a semicircular formation at the head of the city, and after stabilizing the formation, the soldiers slowly moved forward to make room for the soldiers who entered the city behind.

"Da Da Da ......"

The sound of horses' hooves came from within the city.

The Ming army knew that the Jurchen cavalry was coming, and these soldiers, who had never been on the battlefield, suddenly became nervous, they held the flintlock pistol in their hands tightly, and they didn't know that their palms were sweating.

Du Tong stood behind the soldier, he quietly looked in the direction where the voice came from, but he couldn't see anything in the night.

More and more soldiers entered the city, and they constantly joined behind the semicircle, forming three semicircles.

With three rows of soldiers, Du Tong gradually relaxed, what he was most worried about was that when the soldiers were nervous, they would shoot all the bullets in one go, and then they would all have to be loaded, and there would be a long interval of time.

If this is really the case, during the period when the soldiers are loading, they have no choice but to let Jiannu charge, and even kill.

The sound of horses' hooves drew nearer, and the soldiers' hearts tightened, and they even leaned on each other to reduce the shaking of their bodies.

Du Tong also felt it, and he shouted at the soldiers: "The first army and the second army have both captured the three cities of Liaodong, and in front of the flintlock pistol, Jiannu is the lamb to be slaughtered by us." ”

The soldiers were silent, only the sound of Jiannu's horses' hooves, striking them their hearts.

Du Tong saw that the effect was not obvious, he was so anxious that his head was sweating, in case the soldiers were intimidated by Jiannu's cavalry and dropped the chain at a critical moment, the joke would be big.

Du Tong increased the decibel of his voice: "Ma San, do you still want a wife?" Liu Si, do you want to treat your mother's illness? Don't you usually shout that you don't have the opportunity to make meritorious contributions? Now the opportunity to make meritorious service has come. ”

"Yes."

"Yes."

Ma San and Liu Si almost ran to Du Tong's side to sign up, causing everyone to laugh.

"Since you want to make meritorious contributions, then keep an eye on the Jiannu in front, I will watch from the side, whoever shoots and kills the more Jiannu, the higher his military merit will be, and the more rewards he will get."

"Yes, Master." The soldiers replied almost in unison.

"Okay, Jiannu is coming, it's up to you now."

The sound of the horses' hooves was getting closer, and the sound of "da-da" was getting louder and louder, and although the sound still hit the hearts of the soldiers, the soldiers were no longer as frightened by the infinite expansion of the night as they had just been.

"Ready." Du Tong could almost see the figure of Jiannu, and he hurriedly reminded this group of new soldiers who were not new troops.

The soldiers had already raised their flintlock pistols and aimed in the direction from which the horses' hooves came.

"Attention...... Shoot. ”

"Bang."

"Bang."

"Bang."

……

Countless flintlock bullets were fired towards the black shadow in front of them, and the soldiers couldn't see a single Jiannu clearly, they could only shoot bullets by feeling.

Fortunately, there were enough flintlock guns, and the Jiannu at the front fell out of the horse, either the person was injured or the horse was injured.

Because of the darkness, the hit rate of the flintlock pistol was not high, and because of the darkness, the cavalry of Jiannu did not know what was happening.

The Jiannu in front screamed, and when they fell off their horses one by one, the Jiannu behind did not slow down their horses, they just heard a violent and dense sound, and the Jiannu cavalry, which had always been flamboyant, did not stop the trend of impacting, and they didn't even light the torches.

"Okay, good shot, second row, shoot." Du Tong took advantage of the faint light of the flintlock pistol to clearly see that the Jiannu soldiers had fallen from their horses.
