The soldiers who operated the catapults were pierced by crossbow arrows, and their flesh was blurred, and the shafts of several catapults were shot and scrapped. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Shocked, he hurriedly asked people to adjust the direction of the catapult and conduct a third round of shooting, but the catapult was slow to load, and it was troublesome to adjust, and before it could be launched, Jiang Shengjun's second round of fire was ushered in.

More than 200 crossbow arrows flew with the sound of breaking the sky, the Yellow Turban Army was terrified and inexplicable, and it was chaotic, and these crossbow arrows instantly resulted in the lives of nearly two thousand Yellow Turban soldiers.

The four-bow bed crossbow saved time and effort, and the morale of the soldiers was high, and soon thousands of crossbow arrows were fired, the Yellow Turban Army was killed and wounded, and those catapults were also hit by arrows, making it difficult to continue to use.

Shocked, he hurriedly led the army to retreat to the camp for five miles, which was far beyond the range of the four-bow bed crossbow, Jiang Sheng ordered to stop shooting, and then sent troops out of the city to clean up the battlefield, because the crossbow arrows were limited, Jiang Sheng wanted to recycle these crossbow arrows.

The Yellow Turban Army saw Jiang Shengjun going out of the city from a distance, and hurriedly reported to Zhenggu, who sent scouts to investigate the truth and reality, and saw that there was nothing abnormal.

Zhao Yun saw the Yellow Turban Army dispatched on the mountain, so he notified Yu Ban and Zhang He, and the three-way cavalry was dispatched at the same time.

More than 20,000 cavalry came out from three directions, and he was shocked, when did Jiang Sheng have so many cavalry.

The cavalry rushed to the formation very fast, the Yellow Turban Army had no time to retreat, and was surrounded and killed by this cavalry, with heavy casualties, Yu Ban and Zhang He have suffered a lot from the Yellow Turban Army these days, and now they can raise their eyebrows and exalt, regardless of whether the Yellow Turban Army surrenders or not, they will all be killed.

Seeing that the officers and soldiers were red-eyed, he didn't dare to fight, so he hurriedly led his own soldiers to withdraw to the camp.

Zhao Yun wore a white robe, rode a white horse, the silver spear in his hand was like a wheel, the tail chased and killed, the Yellow Turban infantry fled slowly, and was caught up by Zhao Yun.

When Zhenggu withdrew to the camp, there were only a few dozen people left, and more than 10,000 soldiers who went out to fight were all killed by the officers and soldiers, but fortunately, there were still more than 40,000 horses and horses in the camp to guard the gate.

Zhao Yun led the army to rush to the front of the Yellow Turban camp, was killed by intensive crossbow arrows, and hurriedly turned around and retreated.

Jiang Sheng saw Zhao Yun going and returning from a distance in the city, and secretly praised in his heart, it seems that Zhao Yun is not a person who loves war, and knows how to advance and retreat.

Zheng Gu is now a frightened bird, who knows how many troops Jiang Sheng still hid, before the situation became clear, he did not dare to attack rashly, but took Bochang County as a stronghold, and was ready for a long-term battle.

Jiang Sheng now had the confidence to send hundreds of scouts to closely monitor the movements in Le'an, and then began to manufacture mechanized weapons on a large scale.

The ladder car is one of them, Jiang Sheng's new invention of the ladder car has four wooden wheels, the chassis is made of solid wood into a square box, and then the ladder is fixed on the chassis, this ladder is the fire ladder of later generations, divided into three sections, fixed with ropes, and freely adjusted according to the height of the city wall. What's more, this ladder no longer has to worry about being pushed away.

The new catapult has also been built, the new catapult is also equipped with a wheeled chassis, the bottom of the body is a huge wooden gear, can rotate 360 degrees, conducive to the catapult to change direction, with the help of the principle of leverage, the projectile is more efficient, and the shaft can be adjusted to ensure that the range can be adjusted at will. Another significant feature is that the individual parts can be disassembled and combined according to the drawing, which is convenient for handling and on-site assembly.

The armies were amazed when they saw these two things invented by Jiang Sheng, and in this way, I am afraid that no matter how difficult the city is, it will not be able to stop Jiang Sheng's attack.

Jiang Sheng transferred 2,000 people from the cavalry to form an engineer battalion, which was responsible for the operation and maintenance of siege weapons, and Deng Mao served as the Sima of the engineer battalion.

In order to overcome the shortage of troops, Jiang Sheng sent people to various counties to recruit soldiers and expand the troops, forming a scale of 20,000 infantry, 10,000 archers, 15,000 cavalry, and 2,000 engineer battalions, plus logistics baggage troops, the total strength reached 50,000.

In the middle of July of the fifth year of Zhongping, Jiang Sheng's troops had sufficient supplies and had the conditions for a counteroffensive, Jiang Sheng decided to take the initiative to attack, and Bochang became the first battle place for Jiang Sheng's counteroffensive.

The new unit of the engineer battalion was put into use for the first time under the dispatch of Jiang Sheng, and the battle of Bochang began.

The cavalry was divided into two routes, led by Zhao Yun and Zhang He, and stood by in the northwest and southwest directions of Bochang County, Yu Ban led the infantry and the Bochang West Gate to form a defensive formation, Xiahou Lan led the archers to form an attack formation on both flanks of the infantry formation, and Deng Mao led the engineer battalion to assemble weapons outside the city. Yang Feng was the chief supply officer of the whole army, leading his troops to transfer materials.

In a short period of time, Deng Maobu had already assembled sixty catapults, one hundred and twenty ladder cars, and one hundred four-bow bed crossbows.

The soldiers of the engineer battalion all learned the thumb ranging method with Jiang Sheng, quickly determined the distance of the head of Bochang City, and then adjusted the bed crossbow and catapult to ensure that the head of the city was within effective range.

Jiang Sheng gave an order, and all the catapults were put into operation, and the dense stone bullets accurately hit the arrow towers, battlements and defender assembly places at the head of the city, causing huge casualties, and Yu Ban sent 2,000 infantry to help load the stone bullets, and the efficiency was significantly improved.

The defenders at the head of the city were killed and wounded innumerable, and the severed arms and limbs that were smashed flew into the city, and it was bloody.

In the interval between the launch of the catapult, the four-bow bed crossbow shot more than 10,000 large crossbow arrows on the city, and under the cover of the catapult and the bed crossbow, Deng Mao led the army to push the ladder cart to the city of Bochang.

Yu Ban roared, led the infantry to rush forward, and stepped on the ladder cart to attack the city wall.

Seeing that the officers and soldiers began to attack the city, he ordered the defenders to defend with stones and rolling logs, and the officers and soldiers who rushed to the head of the city were quickly killed and retreated.

Jiang Sheng ordered the four-bow bed crossbow to be aimed at the head of the city, and when the official army did not arrive at the head of the city, as long as the defenders showed their heads, they would shoot immediately, this time to kill the defenders, so Jiang Sheng asked the soldiers who operated the bed crossbow to replace them with short arrows.

Under the action of strong elastic force, these short arrows have extremely fast muzzle velocity and are highly accurate at a distance of more than 200 meters.

As soon as the defenders showed up, they were killed by crossbow arrows, and the officers and soldiers on the ladder cart quickly ascended the city and fought with the defenders at the head of the city.

The four-bow bed crossbow and catapult suspended the attack, Jiang Sheng ordered Deng Mao to leave only twenty bed crossbows, and after dismantling the rest, they were transferred to the east of Bochang City to assemble, and Xiahou Lan led the archers to cover.

Jiang Sheng expected that Bochang City would not be defended for long, and that Zhenggu would definitely retreat east to join Bian Xibu in Lixian, so he arranged long-range weapons outside the east gate, and only launched an attack when the Zhenggu army withdrew.
