Gaobeidian is Li Zicheng's heavy garrison area, but also the gateway to the north to the south gate of Beijing, Li Zicheng lived here 50,000 horses, the main general of the team is his general, but also his brother-in-law Gao Yigong.

In the Ming Dynasty, Gaobeidian belonged to Beiping Mansion, and the terrain here is plain, the terrain is not complicated, but the location here is quite important. If Gaobeidian is occupied, the next stop is the Nanzhi Gate of Yanjing, which is equivalent to opening the South Gate of Yanjing.

Therefore, Gao Yigong garrisoned 50,000 troops here, it is worth mentioning that Gao Yigong is not only Li Zicheng's wife and brother, but more importantly, this person is good at guarding, Gao Yigong was born in a martial arts family, has a good martial arts, and has followed Li Zicheng to fight on the battlefield over the years, whether it is with her sister Gao Guiying to protect the women's camp, or with Li Zicheng to charge into battle, Gao Yigong can be alone.

is especially good at defense, so this time, Li Zicheng sent him to guard Gaobeidian, because Li Zicheng knew that it was not so easy to make Lin Yi surrender, and he repeatedly suffered defeats in front of others, and let people surrender to you, which is a bit unreasonable, and it is inevitable to fight a tough battle.

After Gao Yigong received the order, he took the Dashun army here to inspect the terrain, build fortifications, and more importantly, 100 red-coated cannons were ordered here.

In the last years of the Ming Dynasty, the red-coated cannon was undoubtedly the missile of that time.

Now Li Zicheng's men and horses also have a lot of red-coated cannons, which of course he captured from the hands of the official army. He conquered Nanyang, captured Luoyang, and later occupied the whole of Shaanxi, and now out of Shaanxi, fought Shanxi, and captured Beishangjing.

Li Zicheng's men and horses won many battles, and the spoils of war were piled up, including, of course, hundreds of red-coated cannons and ammunition.

Now there are quite a lot of red-coated cannons in the Ming Dynasty, don't look at it as the era of cold weapons, because of the years of war, whether it is the Ming army or the Tartars, they are competing to produce this kind of cutting-edge weapons that kill people.

Although the Ming Dynasty was short of national strength and the treasury could not make ends meet, the imperial court was still willing to spend money in this regard, because the Tartars now also have the ability to produce red-coated cannons.

Although the red-coated cannons produced by the Tartars are all imitations of the Ming Dynasty, their power is not inferior to the Hongyi cannons of the Ming Dynasty.

This is mainly because Kong Youde and Geng Zhongming surrendered to the Tartars, and they brought a large number of red-coated cannons in the team. After the Manchu Tartars got this large number of red-coated cannons, they not only used them, but also began to imitate, as early as the 30s they imitated and produced the first Hongyi cannons, and now the technology of the Manchu Tatars has matured, and they have produced hundreds of their own red-coated cannons.

The battles of Da and Xiao Linghe, as well as the later Battle of Songjin, the red-coated cannons of the Manchu Qing Tartars, fully exerted their power, and the Ming army suffered a big loss.

Because the Ming army has always overwhelmed the other side with the advantage of artillery fire, and the advantage of the Manchu Tartars lies in the Eight Banners Iron Cavalry, the Ming army naively believes that as long as they do not fight in the field, as long as they rely on dangerous cities and artillery fire, they will definitely be able to defeat the Manchu Tartars with these advantages.

But when the two sides really fought, they were dumbfounded, the Tartar artillery roared, the artillery superiority of the Ming army was long gone, and the two sides were balanced in this regard. The Ming army lost its artillery superiority, and it was not possible to fight in the field, so what would it wait for if it was not defeated?

Therefore, in the past two years, Emperor Chongzhen tightened his belt and tried every means to produce red-coated cannons, just like an arms race with the Manchu Tartars, and the number of Hongyi cannons in the Ming Dynasty increased sharply.

Emperor Chongzhen is not stupid, he knows that the Manchu Tartars outside the Guan, that is a small state in the land of projectiles, and their means of production such as iron tools and gunpowder mainly come from the trade in the Guan. As the so-called emaciated camel is bigger than a horse, as long as the Ming Dynasty produces an absolutely superior red-coated cannon, the number can overwhelm the Manchu Tartars, the Ming Dynasty can still maintain the war advantage. Even if they can't keep it, dragging them can bring them down.

Therefore, in recent years, Emperor Chongzhen took the lead in donating, increasing taxes and servitude, and tried every means to increase income, expand investment, and step up the production of red-coated cannons, so the red-coated cannons in the Ming army increased sharply.

But this is beneficial to Li Zicheng, although Li Zicheng does not have the strength to produce this kind of red-coated cannon, he can take it from the hands of the official army. Now the hundreds of red-coated cannons he uses are all snatched from the hands of the officers and soldiers, and now his artillery battalion is also very powerful, and it has played a great role in offensive and defensive battles.

This time, 100 red-coated cannons and enough ammunition were ordered in the Gaobeidian area alone.

Because Li Zicheng knew that their main enemy was Lin Yi, and he didn't pay attention to the other Ming armies, and if Lin Yi wanted to attack, they must come from the south, and Gaobeidian was the first fortress to bear the brunt.

Therefore, Li Zicheng sent Gao Yigong, who was both wise and brave, and stationed 50,000 elite soldiers here. And gave him 100 cannons in red clothes and enough ammunition.

Gao Yigong checked the address of Gaobeidian, and he found that this is a plain area, if you want to stop Lin Yi's men and horses and defend Gaobeidian, you must build a dangerous city and defend it against danger.

Only by knowing oneself and knowing one's opponent can one not be defeated. Of course, Gao Yigong knew that Lin Yi's men and horses were super powerful, and even the Manchu Tartars were not opponents, and the field battle was invincible, so he avoided fighting with them in the field, which was the tone of his battle.

Therefore, after receiving the order of Li Zicheng, the king of Chuang, he took 50,000 horses and horses to build fortifications here day and night.

There are many people who can work. 50,000 people and horses worked together, day and night, and within three days, this small county town was built as solid as gold.

The first is to deepen and widen the moat outside the city.

The second was to strengthen and thicken the city walls, including the four gates.

Of course, these are not the biggest projects, the biggest project is the construction of auxiliary cities on the left and right sides of the four city gates.

The so-called auxiliary city is to protrude a city wall at the city wall, which is square or rectangular, and there are soldiers stationed on the auxiliary city, which are generally on both sides of the city gate, and the purpose of this is to protect the city gate.

Because of the ancient battles, the city wall is directly underneath, especially at the city gate is a dead end, the besieging army really attacked this place, the soldiers above the city defenders could not see, they either hit the city gate or damaged the city wall, the so-called dark under the lamp.

This is the purpose of building the auxiliary city, when the enemy comes to attack the city, the archers or artillery on the auxiliary city can strike at the enemy without leaving a dead end.

In some important large cities, auxiliary cities were built every fifty or a hundred meters along the city walls, and it was necessary to have them on both sides of the city gates to protect the walls and gates.

Due to the special time constraints, this is another small city, Gao Yigong built a total of eight auxiliary cities in Gaobeidian, that is, two of the four gates.

Then for the four city gates, he also built the urn city respectively.

The urn city is at the city gate, outside the city gate.

When the enemy is fierce and the auxiliary city does not work, they can open the urn city, and retreat to the real gate inside the urn city, put the enemy into the urn city, and then come to the urn to catch turtles.

Four city gates, and he built four urn cities.

Then he put all 100 red-coated cannons on the city wall. In addition to the artillery fire, there are also piles of bows and arrows, rolling wood, stones, etc. on the city wall.

As soon as they were ready, Lin Yi's forward troops, Hao Shaoqi's men and horses arrived, this is an army of 10,000, like a sharp knife in front of the road.

Along the way, Hao Shaoqi's army attacked the city and captured the fortress and captured many cities. Now they don't take the small city of Gaobeidian seriously. Of course, they also know that if they capture this small city, they will be able to go north to Beijing.

Therefore, Hao Shaoqi gave an order, and 10,000 troops swept over, and the shouts resounded in the sky.

"Knock Knock Knock ......"

Within range of the red-coated cannons, the cannons on the city roared, and shells exploded in the besieging ranks.

Some of them could kill several officers and soldiers with a single shell, and some of them were blown up with men and horses, and their flesh and blood were blurred, and there were no bones left.

Suddenly, outside the city of Gaobeidian, the smoke of gunpowder was filled, and the ground shook the mountains.

But this could not stop the charging team at all, the front fell, and the back made up, stepping on the blood and corpses of their compatriots, and continued to shout and charge.

After all, the power of the red-coated cannon is limited, it is difficult to form continuous firepower, and it cannot achieve full coverage of firepower.

Therefore, Hao Shaoqi's team, in the roar of artillery fire, burst into smoke and fire, and a charge reached the bank of the moat.

But when their men and horses crossed the moat and began to climb the city with a ladder, they were met with a head-on attack.

The bows and arrows of the city poured down like raindrops, and the walls of the city, together with the city walls, were able to strike at the besieging soldiers without leaving a dead end.

In this way, Hao Shaoqi's team launched three fierce attacks in a row, but none of them attacked the city wall, and the heavy casualties can be imagined.

Hao Shaoqi was not convinced, took off his bare arms, waved the big flagpole, and wanted to charge into battle by himself.

Hao Shaoqi had not yet launched the fourth onslaught, Lin Yi's main force arrived, and seeing the casualties everywhere, countless casualties, Lin Yi looked at Gaobeidian City in the distance and ordered Hao Shaoqi to withdraw his troops.

At this time, He Renlong, the general beside him, took the initiative to ask: "My lord, leave the task of attacking the city to your subordinates, if you can't take it, come and see you."

Lin Yi knew that Hao Shaoqi fought bravely, and his team, if the city that could not be taken down, would definitely be regarded as a strong city, and if it was replaced by He Renlong, it might not be able to take it, and even if it was captured in the end, the price would probably be even more heavy.

Lin Yi shook his head and said, "It's probably not the best strategy to attack hard."

At this time, Hao Shaoqi came over, "My lord, if there is one more charge, the city will be captured, why do you have to collect troops?" ”

"A small Gaobeidian can't be attacked for a long time, who will be the defender of the city?"

Hao Shaoqi wiped the sweat on his face: "Lord Hui, it is Li Zicheng's brother-in-law Gao Yigong, he hides inside as a turtle with a shrunken head, if he dares to go out of the city to fight, his subordinates will already pick him off the horse."

Li Zicheng nodded: "It's not that he doesn't dare to come out, stick to the fortified city, and wait for work, this is his strategy, it seems that the surname is a master."

After Hao Shaoqi's men and horses retreated, they rescued the wounded, buried the corpses, and briefly dealt with the battlefield.

Then Lin Yi took his guards, accompanied by Zu Keyong, Hao Shaoqi, He Renlong and others, and walked around the city, and then nodded: "This city is strong enough, since they are willing to stay inside, then let them be inside, it will be difficult for them to come up this time!"
