The Mongol gunners did not assemble the dozens of artillery trucks until the next morning. These huge rope-throwing machines have been used as siege weapons for a long time.

During the Battle of Guandu, Cao Mengde used a thunderbolt stone cart to break the story of Yuan's original wooden tower archers in the Song Dynasty, which was already a legend passed down by word of mouth among the common people.

At that time, the thunderbolt was nothing more than a primitive stone throwing machine with a height of one foot and five feet and a range of fifty paces. In today's battlefield where Song and Mongolia clashed, it was as ridiculous as a child's toy.

The 100 households in charge of the artillery armies in the distance waved the red flag in their hands, which was a signal to prepare for the cannon.

A team of more than 200 artillery men walked behind a tall artillery cart with one hundred and twenty thick and long leather cords tied to its cantilevers, like thick braided hair on the head of a bearded man.

The hundreds of households in charge of the army shouted loudly, and the artillerymen picked up the piso and held it in their hands. Every two people grabbed a leather cord and looked at the orders of the hundred households.

Someone hurriedly brought a stone bullet and put it in the leather pit, and the fixer sitting on the wooden shaft began to carefully aim in the direction. Dozens of soldiers pushed the artillery cart underneath and turned slowly.

When the artillery truck had completely turned in the direction of the gatehouse, it finally stopped turning.

The 100 households in charge of the army waved the red flag in their hands violently. The two hundred and forty rope pullers shouted in unison, and slammed the leather rope in their hands down.

Seven large, slightly stubbered arms slumped down at one end, and the lever lifted the other end of the leather socket high with a thunderous sound.

A stone bullet weighing dozens of pounds drew an arc with a whistling sound and flew towards the gatehouse.

Under a cool umbrella held high in front of the city gatehouse, Lu Xunzhi sat on a chair and looked up at the stone flying past the gatehouse, and calmly took a sip of the famous hair tip of Hubei Road.

The first test shot was only measuring the distance, and very few actually hit the target.

He was so calm, but the officers and soldiers of the left wing battalion guarding around him were already frightened.

Yang Luo, who was standing on the inner wall and watching, watched as the stone bullet flew over the gatehouse and landed on the top of a military house dozens of steps behind the wall, and immediately blew half of the roof of the military house away.

The soldiers and civilians in the village have already moved to the mountain, and only the necessary fighters remain below the wall, ready to start a war of throwing stones.

Yang Luo saw that the house was a warehouse stacked with wine syrup, and he was furious, turned his head and shouted at Lu Xunzhi: "Commander, can we fight back?" ”

Lu Xunzhi shouted: "Fight back!" Turning around, he still said to Ma Xiang, the left-wing battalion commander next to him, in a calm tone: "Let's take a cool umbrella and go into the battle shed, it's really here." ”

Yang Luo shouted towards a huge artillery cart dozens of paces behind the wall: "Bing position, put it!" ”

The fixed hand on the Mongolian army's seven-tip artillery cart was still annoyed by his miscalculation, and instructed everyone to turn the artillery cart around, when he suddenly heard a familiar wind in the air.

A stone bullet in the opposite wall flew towards him with a more violent momentum. It smashed the huge seven-tip cannon cart.

The boulder kicked up a huge amount of smoke, and in the smoke and dust, the seven-tip cannon cart that the Mongol army had carefully built for a day was beaten to pieces like a wooden toy built by children, and the two Dinglet hands were shaken into the air with huge cantilever in the exclamation, and they fell heavily into the dust together.

Yang Luo was overjoyed and shouted at the wall: "The first hit is the first hit!" ”

A burst of cheers erupted from within the wall.

There is also an advantage of being able to have a few more months to prepare, that is, the artillery operators can take a good time to test the open space in front of each launch position, record the results of the test release one by one, and finally compile the range of the artillery truck in front into a detailed grid, which point on the grid should be set what direction and scale, all practice one by one in advance, and then the lookout hand on the city wall reports the direction according to the longitude and latitude of the marked Lang, although it is very convenient to adjust it if it cannot be hit immediately.

This is the huge advantage caused by the different status of the host and the guest.

Yang Luo raised his eyes and looked, and the Mongolian army's stone throwing machine position on the opposite side was in chaos.

The shock brought by the destruction of a seven-tip stone throwing machine was far less than the panic caused by the thought of "ah, there will be such a high-end stone throwing machine on the other side".

Generally speaking, the cottages of the Song army were guarded by inferior equipped van soldiers, city defense troops, or simply militiamen, and there were very few heavy machinery such as stone throwers.

Even though the fortress was imposing, the Mongols still made a quick judgment in advance that the enemy would not have a trebuch.

That's why they limited the main target of the stone thrower to wooden walls. Just destroy the defenses of the North Gate with stone bullets from a safe distance, and the rest is as simple as possible.

However, the appearance of the defending side of the trebuchet escalates this game with zero danger into a brutal catapult strangulation battle.

"Bingyin, put!" A lookout not far from Yang Luo shouted towards the city.

The three artillery carts violently raised their cantilever arms in unison, and the stone bullet pierced the sky like a meteor.

This time, the Mongolian artillery armies really recovered from the shock and began to counterattack under the command of the commanders. However, they could not see the specific location of the opponent's catapult in the walled city, and could only deduce the approximate location of the opponent's firing position from the projectile shot.

Despite this, they still tugged desperately on the piso, throwing one shot after another of mud pellets and stone projectiles towards the imaginary enemy army.

This way of counterattacking is absurd and inefficient, but it is a desperate struggle of the weaker side under conditions of information asymmetry. In the north, the Mongolian artillery soldiers who blasted the famous cities with dozens of pounds of boulders showed their pride and perseverance in such a unique way.

And from the perspective of practical effect, such a blind counterattack still has a certain intimidation and damage to the rats who hide on the other side of the wall and refuse to show their heads.

Under the rocky rain, two five-seater cars suffered fatal damage and were forced to give up, and the remaining single-seater, four-seater and seven-foot cars of different sizes were partially injured. The gunners of the two artillery carts were frightened by the stone bullets, threw off the artillery carts and fled, hiding in caves in the mountains.

But compared to the earth dragon gunners who calibrated and shot on the city walls, this was a fight between the blind and the able-bodied.

Instructions for directions and corrections came and went on the wall, and stone bullets and mud pellets rained down one enemy artillery truck after another, and even Yang Luo, who was watching the battle on the wall, was a little surprised. Many of the Mongolian gunners had been shattered by the stone bullets, and blood was splattered on their companions' bodies, but the remaining gunners continued to pull Piso unwaveringly. His tenacious will to fight, even Lu Xunzhi couldn't stop exclaiming: "It really deserves to be the elite division that defeated the Jurchen army!" ”

However, it was impossible to save the defeat after all, and the number of artillery vehicles on the Mongolian side gradually decreased, until the last one was still firing a single artillery that was hit by more than a dozen stone shells and finally collapsed, and the first day of the artillery battle ended with the complete defeat of the Mongolian artillery army.

At this time, the Mongol position was full of broken wooden beams, axle posts and pisos, the artillerymen moaned weakly between the wreckage, and the Mongolian soldiers in the brigade completely ignored their wounded comrades, frantically searching for parts that could still be used in the wreckage.

Yang Luo, who witnessed this scene, said to Lu Xunzhi: "Lu Weng, there is a real battle next. ”

"Next time it won't be as easy as it was today."

Fortunately, before this next time, it would have to waste a lot of time for the Mongol army to restore the combat effectiveness of the artillery army.

This time, the Mongol army could see that it was simply a whole army, and almost all the trees on several mountains were cut down, and the timber was sent to the camp at a high price.

They're building more artillery trucks than they were the first time, and that's not all.

At dawn the next day, the lookout post on the walled wall found that a huge wooden building had been erected on the opposite side.

Before erecting the artillery cart, it is necessary to set up a watchtower to look down on the enemy's garrison in the city, especially the specific location of the stone throwing machine in the city.

In the battle of Zaoyang, the Mongols set up a watchtower more than ten zhang high, peeped into the city day and night, and then destroyed the stone throwers in the city one by one according to the command of the lookout post, and won the victory.

The Mongols suffered from the carelessness of the enemy during the attack on Lao Yashan, and this time they decided to start in a solid manner according to the usual steps.

Of course, the garrison side also looked at the watchtower on the opposite side and was anxious, Yang Luo visually measured that the watchtower was outside the range of his own artillery truck, and even moved to send an assault team to trap and destroy the idea of the watchtower.

But he was fond of trickery in his life, and such a hard-bridged approach was contrary to his philosophy of war.

What's more, the assault team is either an iron cavalry formation, taking advantage of the advantage of mobility to attack quickly, and leave with one blow before the enemy can react. Or to motivate the three armies, with a small number of elite infantry detachments to open the city and fight, use the momentum of one blow to overwhelm the opponent, and seize the temporary initiative on the battlefield.

There were no cavalry in the Tulong Army, nor did they have elite infantry that had been through the battlefield to use. Now open the door and kill the enemy, in addition to giving the enemy's powerful ironclad cavalry heads, it will also damage the already very weak garrison in the city.

Before Zheng Yunming returns, he must firmly hold Dazhai, and not a single soldier can be wasted.

Looking at the high-rise building opposite, more than ten strategies swept through Yang Wei's mind in a short period of time, but he was vetoed one by one.

Yang Luo, who claims to be unparalleled in his calculations on weekdays, can only sit and watch a few towering watchtowers slowly build out, and the lookout hand is looking down on the situation in the walled city from the upper floor, and will record one by one, tomorrow's battle is destined to be a fierce battle for the Tulong army.
