readx;???? The Chu army did not launch an offensive against Jimo the next day, because after thinking about it for a while, Xiang Yu believed that the troops needed to be more prepared to be more effective against Jimo's attack. Pen ~ Fun ~ Pavilion www.biquge.info [For more exciting novels, please visit]

But what Xiang Yu didn't expect was that some Qi people from nearby who claimed to be driven out of Jimo City were found by Xiang Zhuang, and the information they said was quite limited and even wrong.

This is undoubtedly a serious misleading situation for Xiang Yu.

It is because of this that it is undoubtedly very fatal for the Chu army. Because from top to bottom, they had a wrong perception of the Qin army's defense capability in Jimo City.

In fact, after Zi Anxun and Wenle drove the Qi people of Jimo out of the city, they officially began to modify and strengthen the city fortifications in the Jimo area.

Although the focus of Liaodong military construction has gradually shifted to Jixian military construction and Xianyang military construction in recent years, on the original basis, Zhang Jiashi has vigorously developed the cold weapon production capacity of Liaodong weapons.

Especially in terms of urban defense equipment, the production capacity of Liaodong military construction in this area is the strongest among the four major military construction (Liaodong, Jixian, Taiyuan, Xianyang) under Zhang Jiashi.

This is an important piece of information that Xiang Yu can't clearly understand.

......

The urban defense system in the Jimo region is far from being comparable to the time when Tian Heng served as the king of Qi.

The main addition to the city's defenses was the ability to maneuver with light throwing wagons and a large number of fuel bombs.

The effectiveness of this weapon as a garrison is not inferior to that of many fortifications.

Of course, most of these oil bombs are not crude oil bombs similar to the "Greek fire" formula of Zhang Jiashi, but the fuel oil extracted from ordinary oil pressed crops.

(Greek fire (Greek: Υγp?Πup) is a liquid incendiary invented by the Byzantine Empire that can burn on water, it is an early thermal weapon, mainly used in naval warfare, "Greek fire" or "Roman fire" is just the name of the Arabs for this terrorist weapon, and the Byzantines themselves call it "fire of the sea", "mobile fire", "liquid fire", "artificial fire" and "fire of defense" and so on.) According to the literature, Greek fire contributed to the military victories of the Byzantine Empire on many occasions, and some scholars and historians believe that it was one of the reasons why the Byzantine Empire lasted for thousands of years, and the recipe of Greek fire is now lost, and the composition remains a mystery to this day, according to the Crusaders who were wounded by Greek fire at the time: "Whenever the enemy attacks us with Greek fire, all we do is to kneel down and pray for salvation from heaven." That quote is enough to illustrate the power of Greek fire.

It is generally believed that the firing device of the Greek fire probably consisted of oil tanks, manual air pumps, conduits, nozzle ignition and other essential components. The tanks were placed below the deck of the ship, and the conduits were held by a strong soldier who could adjust the height and angle according to the situation. The role of the manual air pump is very crucial as it is the power source for the injection of Greek fire. Before spraying, the Greek fire is heated and pressurized, so that when the valve is opened, it will surge out, and the ignition mechanism at the nozzle of the ejector will ignite the passing liquid at any time, so that the final ejection is a flame.

The ships that carried Greek fire were also specially designed, small in size and nimble in movement, but very strong in defense, probably wrapped in heavy and soaked animal skins, especially with elite archers, which the Arabs called "fire ships". When approaching the enemy ship, under the cover of the archers, one soldier activated the air pump to pump the Greek fire into the tube, while the other activated the ignition mechanism at the mouth of the pipe, and the powerful soldier held the guide and fired the Greek fire at the target. Under strong air pressure and the encouragement of the wind, the flames would burst out 50 yards at once.

With the improvement of production technology, the Byzantines also loaded Greek fire into high-pressure, temperature-insulating launchers, and ignited them before spraying, so that the spray was a raging flame, which was more suitable for close-quarters combat and emergency use. Alternatively, the jet tube may no longer need to be held by a person, but instead fixed to the bow of the boat, but with a pulley at the fix, so it can be reoriented. It is worth emphasizing that in either case, the ejector's tube should stick far out of your ship, which is very important in terms of fire attack.

In fact, Greek fire was used in a variety of ways, either by spraying it on the surface of the sea and then igniting it with rockets, or by placing it in oil cans and pouring it from the head of the city to the besieging enemy, and then igniting it. From some medieval drawings, it is possible that the above-mentioned Greek fire ejection device was also used in land warfare, especially siege warfare. What's more, the fire will also have a powerful shocking force, thus playing a role in disintegrating the enemy's combat effectiveness.

Greek fire was mainly used in naval warfare. According to the legend of the time, Greek fire could continue to burn in any environment, even in water. The Byzantine enemies described it as a "wet, thick, and black" fire, because the Greek fire could not be extinguished when it stuck to the target, which gave the Byzantine army an overwhelming advantage in naval battles. Its last use was during the Siege of Constantinople, after which the Greek fires were lost with the burning of the Ottoman Empire. ）

Zhang Jiashi did not think about developing a weapon similar to "Greek fire", but in many ways, in the absence of corresponding scientific and technological support, Zhang Jiashi gave up this method of spitting, and developed the proportion of oil itself as much as possible according to the comparison of "Greek fire".

This is also the kind of oil bomb Although this kind of oil bomb cannot be compared with the effect of the crude oil bomb produced by Zhang Jiashi in the Xianyang Military Factory, in many ways, this kind of oil bomb produced by using oil crops as raw materials has a relatively lower production cost and higher output.

......

On the city walls, a large number of improved city defense equipment have been replaced or used to strengthen the defense effect of the original Jimo city defense system.

In particular, the kind of multi-layered crossbow that can be quickly reloaded developed by Zhang Jiashi's order is all over the city wall of Jimo.

This crossbow has been improved to carry three rows of large instruments of about 20 pieces each.

Under normal operating procedures, this bed crossbow is capable of firing three rows of sixty crossbows in twenty seconds.

Moreover, with the corresponding process improvements, the reloading of this crossbow is also very fast, and a skilled crossbowman can use the corresponding equipment, and it takes six seconds or a little more to load ten rounds of crossbows.

This is also an improvement in the way of loading, of course, in order to achieve such a reloading speed, the crossbow itself is designed to be quite long and heavy, which simply cannot meet the needs of field operations.

Of course, in addition to the situation of defending the city, the effect of this crossbow is quite good if it is used for ambush warfare.

After all, if there were thirty of these crossbows in an ambush area, then the firing frequency of such crossbows in the initial period would be a devastating blow to the enemy at an effective range of three hundred meters.

............................................................ Dividing line ..........................................

One thing Xiang Yu didn't expect was that he would encounter the first actual battle of the strongest defense system of the Great Qin Empire.

After all, after Zhang Jiashi determined the rule of the Guanzhong region, the luck was quite good, and the geographical factor also had a great advantage, after Zhang Jiashi occupied the Hebei region, it almost became an insurmountable natural danger of the river, and became the most advantageous geographical advantage of Zhang Jiashi.

Zhang Jiashi's land in the Hebei region did not suffer from military disasters again, let alone in the more northerly areas.

Therefore, Zhang Jiashi's gradually replaced city defense equipment actually has no room to play a role.

This time, the urban defense equipment in the Jimo area was more transported from some minor counties in the eastern Liaodong region.

The cities that really house the better equipment are not dismantled by the equipment they are equipped with.

Especially along the Great Wall, whether it is Sujiao or Ji, they don't want to pay a heavy price for their original decision because of their momentary misjudgment, which will lead to a sudden war in the future.

It's just that, despite this, the Chu army soon saw that these local Qin army troops, which were more composed of Shang County personnel, and their combat effectiveness was still very different from the Liaoning County system next door, but it was not a force that could be bullied by the Chu army with a strong city defense and a perfect city defense system.

On April 17, 202 BC, the Chu army, which had been prepared accordingly for this battle, launched a fierce attack on the Jimo region.

However, even Xiang Yu himself miscalculated one point, that is, Zi Anxun and Wen Le determined the means of hiding the defensive force before the Chu army launched an attack.

This means that they don't need to let their officers and men show their full power from the start.

......

At this time, the Chu army had already determined to form a comprehensive encirclement of Jimo City except for the sea.

Of course, Xiang Yu didn't think about even blocking the sea, but in the face of several skirmishes in the face of the most elite sailors of the Great Qin Empire, the Liaoning Lou Boat Soldiers, the relatively weak sea troops of the Chu State were all killed by the other party.

Therefore, Xiang Yu thought of one point, that is, it was impossible for them to completely annihilate the Qin army that occupied Jimo.

However, this did not affect Xiang Yu's confidence in winning the battle.

If Zhang Jiashi knew Xiang Yu's thoughts, he would spit out a bad idea to Xiang Yu angrily: "It's a good thing to have confidence, but it's another thing to have confidence and whether you have the foundation to do this."

It's just that it is impossible for Xiang Yu and Zhang Jiashi to sit down and communicate because of this situation, and Xiang Yu soon knew a fact, that is, the defenders of Jimo are not easy to mess with.

Or that Jimo's city defense system allowed him to see the true meaning of what is called a turtle shell.

......

"Charge !!"

Accompanied by the orders of the officers of the Chu army who commanded the front-line troops in several directions, a formation of more than 5,000 people, or even about 10,000 people, launched a charge against Jimo.

While the infantry troops and a large number of siege vehicles were advancing, there were also a large number of arrows and stones fired by the strong crossbowmen of the Chu army in the sky, constantly flying towards Jimo City.

However, in the case of a fairly high height of the city wall and a longer range of the defenders' strong crossbows, the waves of fire between the two sides made the casualties of the Chu army even heavier.

Many times, the strong crossbowmen of the Chu army who were counterattacked were injured or even hit by the arrows falling from the sky before they could fire more arrows.

Faced with this situation, Xiang Yu, who was in a relatively safe place, expressed his helplessness. After all, he also knew that the current Qin army was no longer the original Central Army of the Great Qin Empire that he had beaten from the giant deer.

And Zhang Han had already died in Zhang Jiashi's offensive, which further illustrates the success of the king and the defeat of the king.

However, it is obviously impossible to get him so easily.

"Ah!!h

Screams from both sides were heard one after another, but if there was such a thing as a military observer mission on both sides, there would be a comparison, that is, the casualties of the Chu army were even heavier.

However, this did not stop the offensive of the Chu army, but allowed the Chu army to continue to launch an attack on Jimo.

On the siege vehicles, the crossbowmen of the Chu army desperately suppressed the defenders of the Jimo city wall, but at this distance, the crossbowmen of the Chu army on these siege vehicles could not see more of the situation, especially at a relatively close distance under the city wall, some packing trebuchets operated the Qin army to reload the oil bombs.

The range of these packing trebuchets was very long, but some of the arrows that were fired into the city still cost some Qin officers and soldiers who operated them, delaying the combat efficiency of these trebuchets.

However, as the cluster bombs were prepared, the packers were quickly launched after the fuses of the bombs were ignited.

This type of cluster oil bomb is mainly a temporary binding of five oil bombs with some ropes soaked in oil.

These bombs are not very reliable, but in many ways they have a wider impact area, and in many cases, they are able to create a greater range of incendiary fire.

If the bombs are reliable, for example, if they are effectively ignited in the event that the rope is burned in the air, then the combat efficiency of these bombs will be much higher.

And the oil bombs scattered in the sky in the Chu army's formation or on the offensive road will become a fireball that gradually burns in the sky.

These fireballs collide on the ground and are easy to explode, and then the flying viscous oil stains the Chu officers and soldiers, and it is easy to burn these Chu officers and soldiers or even directly burn each other.

What was even more unfortunate was not the officers and soldiers of Chu who were directly burned by oil bombs, but a few engineers who were hit by several oil bombs and quickly ignited a fire.

Many Chu officers and soldiers could only forcibly jump from the siege vehicles more than ten meters high before being suffocated by these poisonous smokes......
