In 245 B.C., the second year of the succession of King Yingzheng of Qin, Duke Yingwei led an army of 100,000 to attack the important border town of Juancheng in Korea. During the Warring States Period, the city was an important stronghold of the Chu State in the north into the Central Plains, located at the throat of the Jingxiang Road, and has always been an important place for soldiers.

The 100,000 troops led by Duke Qi Yingwei were only the Qin army in the middle lane. In the north, the Qin army of the Northern Road led by the general Meng Wei gathered on the border of Qin and Zhao, coercing Zhao and not daring to rescue South Korea. At the same time, the southern Qin army led by the general Wang Yi in the south was entrenched on the Qin-Chu border, wantonly showing off its force, forcing the Chu State not to dare to support Korea.

Although the mid-route Qin army led by Gong Yingwei only had 100,000 troops, it included the elite troops "Ruishi Battalion" and "Trap Camp". In addition, the Qin army is also obviously letting the recruits get actual combat training this time.

The Qin State developed agricultural production through the Shang Dynasty reform, formulated the "Military Merit System", and greatly improved its national strength, so it founded the "Ruishi". To screen out a thousand soldiers from the 100,000 Qin Army, they must first pass the physical fitness test. The soldier was fully armored, a broad-bodied short sword, a fine iron dagger and a cowhide shield, and the total weight was about 80 catties. In addition, a skill test is also conducted, on the one hand, to test the individual's ability to fight with various weapons, and on the other hand, to test the team's combat ability in various formations. Soldiers who pass the test become a member of the "Ruishi". These sharps are like beasts that choose people to devour.

At the same time, whenever the Qin army encounters some extremely dangerous tasks in battle, the warriors who are not afraid of life and death and have no consideration for life and death will stand up and defend the undefeated honor of the Qin army with their blood! This iron-blooded army is likely to be the first official 'death squad' in history, and these warriors have basically never returned. It's really a brave man under the heavy reward!

There are two elite units, the "Sharp Soldiers Battalion" and the "Trapped Camp," and there will be no accidents in this actual combat training.

The army in the middle of the road marched quickly to the border of Qin and Han, and the front of the army was directed at the city, intending to conquer this fortified city within a month.

The 30,000 Qin troops set up their troops under the rolling city, exuding a dignified murderous aura like Mount Tai rushing to the fortified city garrisoned by the enemy.

The Korean army at the head of the city was cowardly before fighting, and the sound of riots was endless.

"No wonder the Qin army can dominate the world and be invincible, and it can actually scare the enemy trembling just by relying on momentum!" Centurion Meng Yi sat on his horse and said excitedly.

"Of course, but there are pros and cons to everything. It is precisely because the field combat capability of the Qin army far exceeds that of the six eastern countries that no country in the six countries dares to fight us alone in the wilderness. So today's warfare is mainly siege warfare. As the elder brother, Meng Tian naturally has the obligation to teach his younger brother the art of war and strategy, explaining in detail.

"In that case, wouldn't our cavalry be safer?" Meng Yi said with a smile, as if it was a great joy not to have to go to the battlefield to fight.

"Having said that, but there is no feats without fighting, are you equivalent to a centurion for a lifetime?" As the grandson of the Mengjia family, Meng Tian naturally looked at his younger brother Meng Yi with hatred, hoping to inspire Meng Yi to get ahead.

"Military merit is not my wish, but I hope to return safely." Meng Yi was still unmoved, and said with a smile.

"Safe return? I think you're a shrunken turtle! Meng Tian angrily accused loudly.

"Big brother, don't underestimate turtles, haven't you heard that turtles live long?" Meng Yi was not angry but happy, and laughed.

Meng Tian was so angry that he couldn't wait to drag Meng Yi off the horse and beat him violently. But who knew that Meng Yi had already seen that the momentum was not good, and immediately beat the horse away. Fortunately, the two brothers just fought in private, which did not affect military discipline, and Gong Yingwei would open one eye and close one eye when he saw it.

Compared to the cavalry, the infantry did suffer badly. In ancient cold weapon warfare, the besieging side often had to pay a huge price, and it took a fortified city after a brutal siege battle. The Qin army touched the strategic city of Juancheng, and immediately hit the head and bled out.

"The art of war pays attention to the right fit and the odd victory. The fortified city is so difficult to fight, why not bypass it? Meng Yi really couldn't understand that the Qin army had given up its superior field combat capabilities, and instead consumed the lives of a large number of soldiers to attack a small city with no name.

"In fact, most of the cities do not have to be fought, and it is okay to go around. However, some cities, such as the pass ferry or the strategic city, cannot be avoided no matter what. Because once it is bypassed, it is very likely that the enemy's logistics supply will be cut off, and then our army will have to defeat itself without a fight. "Although the city is small, it is indeed a strategic barrier for Nanzheng, the capital of South Korea, and once the city is captured, it can be a direct attack on Nanzheng, the capital of South Korea."

"The scale of the cities in the Spring and Autumn Period and the Warring States Period is not very large, but the effect is very obvious. At that time, the city was mainly used as the administrative center and economic center of a certain region, and it also played a role in gathering population and controlling the surrounding countryside. Because of the importance of cities, they are often the main targets of the attackers in the event of war. "Anyway, the cavalry is only responsible for the vigilance task, so Meng Tian simply pulled Meng Yi and explained some common sense of war.

Looking at the sturdy and towering city in the distance, Meng Tian continued, "In order to prevent the enemy from invading, the city often builds high walls around it. There is no doubt about the defensive role of the city walls. When the city is attacked by the enemy, the soldiers defending the city can rely on the city walls to launch a fatal blow against the invading enemy. Therefore, in the event of a siege battle, it is basically impossible for the attacking side to break through the city if it does not have an absolute superiority in troops. ”

Meng Yi comprehended, nodded in agreement: No wonder in order to attack the city more effectively, the generals of various countries led the skilled craftsmen to invent some powerful siege equipment, such as rushing cars, ladders, and catapults. These siege equipment played a huge role in siege warfare and put a lot of pressure on the defenders. However, siege equipment is effective against small and medium-sized cities. However, if it is a large city with high and strong walls, the effect of siege equipment will be greatly reduced. Therefore, when attacking large cities, the siege method becomes very important. ”

Seeing that his younger brother Meng Yi was interested, Meng Tian was naturally willing to teach a little more military knowledge, "It's true, there were many siege methods during the Warring States Period, depending on the size and geographical location of the opponent's city, different methods can be used, or a variety of methods can be mixed and matched. If it is a low-lying city along the river, then water attack is definitely a good method. If it is a city in the plain area, or if the geographical location of the city is high, the water attack will definitely not work. Assuming that the defending forces intend to defend the city to the death, then the best way to do this is to besiege the city, that is, to besiege but not to attack. The city is populated, and once it is completely surrounded by enemy troops, the food reserves will soon be depleted, and the city will be destroyed. ”

"But I think the boss Qi Gong seems to only plan to storm the city, why not take the method of besieging but not attacking?" Meng Yi asked with some confusion.

"This is also a last resort! The city is strong, the grain and grass are abundant, and there are reinforcements from outside, if you take the siege but not attack, I am afraid that it will not be able to be captured for two years. Meng Tian directly pointed out the reason for the matter.

"In this case, the number of casualties of tens of thousands of soldiers is not a small number." Meng Yi sighed a little unbearably.

"Don't worry, Coach Qi Gong is also a general who can fight well, how can he not understand the mystery?" Meng Tian is obviously in his chest.

"You're saying that Gong Qi has other plans a long time ago?" Meng Yi asked with some sudden realization.

"Wait until evening, you'll know." Meng Tian rarely sold Guanzi.

At this time, the war drums under the city rumbled, and the arrow array of the Qin army continued to fire crossbow arrows to shoot the enemy troops on the city; The trebuchets built by the Qin army overnight also did their best to shoot boulders and other debris to kill the enemy army. If you want to attack the city wall, you must first step over the wooden horses and traps outside the city wall, and fill in the moat, and then you can push the ladder to the city wall.

So first of all, thousands of infantry either attacked the city gate with siege engines, or carried sandbags to fill the moat.

After the moat was filled, thousands of Qin infantry with long swords and shields or rushed to the city wall with cloud ladders, shouting loudly to stop the clouds and roll up dust.

"The ladder can stand against the clouds, so you can overlook the enemy in the city, climb high and look far away to detect the enemy."

During the Warring States period, the ladder consisted of three parts: wheels, ladder bodies, and hooks. The ladder is generally believed to be invented by the skilled craftsman Gong Yi Pan (Lu Ban) in the Spring and Autumn Period, when King Chu Hui ordered the Gong Lose Pan to make the first cloud ladder in history in order to achieve the purpose of dominance. The ladder body can be lifted up and down, and it can be carried and leaned on the city wall by manpower; There is a hook at the top of the ladder, which is used to hook the edge of the city; The ladder body is equipped with wheels, which can be pushed to drive, so it is also called "ladder car", equipped with anti-shield, winch, grappling hook and other appliances, and some are equipped with pulley lifting equipment.

However, climbing the ladder is quite dangerous, and it can be attacked by enemies from all directions at any time. The first is the enemy directly above, who will use rolling logs, stones, and gold juice to prevent them from climbing the ladder. The golden juice is made of dung and poison, and it is boiled over a fierce fire before being watered, and once it is touched, the skin and flesh are immediately opened, and the poisonous juice quickly seeps in, and almost all of them are killed instantly. Even if you are lucky enough to dodge, you will have to suffer from intensive fire from archers from all directions. It can be said that the first person to climb the ladder will become cannon fodder nine times out of ten.

So who will be the first climber? Quite simply, encourage the soldiers by rewarding them. The first person to climb the city wall was called "Xian Deng" in ancient times, and the first person to ascend was recorded as the first merit, even higher than the killing of the enemy general. Under this kind of heavy reward, there will inevitably be brave men, and many of those who can win the "first climb" have become generals. After the "Shang Dynasty Reform", the soldiers of the Qin Dynasty were extremely fierce in attacking cities and territories, because the Qin Dynasty had a military merit system, as long as they were the first to ascend or kill the enemy, they had the opportunity to get titles and land and real estate.
