The first expedition of the First Cavalry Regiment of the Han Army can be regarded as a good start, but the deficiencies exposed are not the slightest.

First of all, Xu Zhi, who commanded a large-scale cavalry for the first time, was still immature in his judgment of the fighters, although he faced up to the fact that the cavalry had high mobility and knew how to divide the troops, and used its fast combined forces to pounce on the enemy's relatively large number of Chinese troops, but the judgment was wrong Tian Guang's mentality, and he also ignored the restrictions of the city on cavalry.

In addition, the cavalry was the first large-scale long-distance attack, and some preparations were not in place. For example, the importance of the location of water sources, the repeated determination and judgment of the terrain, the endurance of cavalry horses, and so on.

50,000 cavalry light cavalry for one person and two horses, heavy cavalry for one person and three horses, in addition to exchanging horses for riding, pack horses carrying food, water bags, weapons and other materials are even more indispensable, the total number of horses carried by the First Cavalry Regiment is close to 230,000, although the so-called drinking horses and water are exaggerated, but the drinking water of so many horses is definitely an exaggerated number.

At the beginning of the attack, Xu Zhi thought that since there were so many water sources, the water source must be guaranteed, but he ignored a very strict problem, that is, the army was in a state of attack, and it was impossible to run to a place far away from the battlefield to drink water when it was in a combat state.

Successfully attacking Tian Guang's front and rear armies, why did Xu Zhi delay the time when he turned his troops to point to Tian Guangzhong's army? It was the negligence in the selection of the place of engagement, and the miscalculation of the fatigue of the cavalry, and the result was that the two cavalry units that had divided their troops took more time than expected to return to the assembly of the main force after the battle, and the army waiting for the re-round was about to carry out the second phase of the battle, and Tian Guang slipped into the city to stop sparring.

Then Xu Zhi and the first cavalry corps of the Han army seemed to be a success, but the deployment of the battle plan was only the completion of the first stage, and the Qi army had already taken refuge in the city. In the second stage, the plan to nail Tian Guang's main force to the wilderness could not be implemented.

It is difficult for cavalry to attack the city without siege equipment, in fact, even if there are siege equipment, valuable cavalry is not allowed to fight a war of attrition to attack the city, Xu Zhi only let Tian Guang's main force nail in the wilderness at this stage, and bring the troops to the intersection of Surabaya and Yishui, that is, about five miles northwest of Xiapi.

The northwest area of Xiapi City is all flat, and the movement over there can be seen from the head of the city.

With 230,000 horses and tens of thousands of soldiers, the area occupied will not be small, and the activity area of the Han army is even forced to a position about two miles from the city wall of Xiapi.

The horses trampled and roared too loudly, and the sound of "booming" horses' hooves disturbed the whole Xiapi city unpeacefully, and the residents of the city naturally thought that Xiapi had become a battlefield. The Han army has not yet made any posture of attacking Picheng, and the city is already in chaos.

Even if Tian Guang didn't know much about the cavalry, he could see that the Han army did not carry siege equipment at all, let alone see that the Han army was cutting wood to prepare siege equipment, so the attack and defense of the city was naturally impossible. He found that there was chaos in the city and immediately dispatched soldiers to suppress it, but he was not sloppy at all about the defense of the city wall, after all, the Han army even bypassed Pengcheng and directly attacked Donghai County, who can know if there is a more unexpected move?

Xu Zhi originally wanted to lure Tian Guang out of the city to fight with a casual attitude, but the gate of Xiapi City was always closed, and the drinking water and rest of his army were immediately completed. He only walked around Xiapi with all his might, leaving some necessary rangers on the periphery to deal with the fast horses that Xiapi might send to communicate with the outside, and then led his troops to the southeast.

Tian Guang, who had been paying attention to the movements of the Han cavalry at the head of the city, was also relieved to see the enemy leaving, and the Qi army he led his troops south was some new army that had not been formed for a long time. If you fight an offensive and defensive battle in the city, relying on the city wall to defend the new army, even if it collapses, it is within the city wall, and if you fight a field battle, it is estimated that it will be like the front army and rear army that have been wiped out and scattered in the wilderness, and the huge establishment will disappear in a blink of an eye.

The large-scale cavalry of the Han army slaughtered Donghai County. Tian Guang naturally wanted to send someone to report this military situation, and he dispatched a fast horse out of the city, still thinking about something in his heart. The fast horse out of the city ran out of the city for two or three miles, and the Han cavalry, who didn't know where to hide, came out again, and he watched his fast horse being killed by the Han cavalry.

"Is that a crossbow or a bow?" Far away, Tian Guang saw that his fast horse turned around and wanted to run, but the Han cavalry did not get close to hand-to-hand combat, and his fast horse fell directly from the horse.

The Han army rangers are equipped with riding crossbows, the early Qi and Han scouts have been in skirmishes with each other when the intelligence has already been discovered, Qi has always wanted to capture a few riding crossbows for imitation, and the back has really obtained a few riding crossbows, but the structure of the riding crossbow is not so complicated, but it is scattered as soon as it is disassembled, they reassembled for a long time and failed to reassemble those parts, and finally successfully assembled a pair, and when the imitation was carried out, it was found that the parts of the same appearance could not be assembled like the Han Kingdom, Even if a few imitations are successfully assembled, they cannot compare to the Han army's riding crossbows in range.

The assembly line process of the Qin State has been invented for one or two hundred years, and the countries naturally know and imitate it, and many behaviors are easy to imitate, but the core area is not successful by imitation alone, and the countries have never understood a key, that is, the importance of measurement.

The production of the assembly line is strict about the size of the product, for example, the proportion difference of any part cannot exceed how much, for example, the Qin State stipulates that the difference cannot exceed how many millimeters...... Of course, at that time, there was no measure word for "millimeter".

The nations have never grasped the core knowledge of assembly lines and mass production, and they strangely regard the strict inspection of the products of the craftsmen of the Qin State as a kind of brutal act, because if there is a problem with the products made by the craftsmen of the Qin State, they will either be flogged, cut off something, or even more simply executed.

At the same time, because of Lu Zhe's storage, the modern concept of meters, centimeters, and millimeters will inevitably appear, and the measurement degree has been continuously improved, and the accuracy of millimeters has been the limit in this era, and there are substantial improvements in molds.

In today's era, it can be regarded as a kind of "high-tech" for the parts assembly mode, Qi Guo can't even play with the most basic assembly line, and the product is only limited to the premise of qualified quality and not paying attention to size, even if they get the crossbow of the Han Kingdom? Maybe it can be imitated, but the yield rate is absolutely pitiful, and a small number of elite soldiers can do it, but large-scale assembly is impossible.

There is no shortage of elites in every collective, and this is even more true of the army, Tian Guang can't see whether the Han army rangers use bows or crossbows, and they don't use another method to judge, but some people can.

Yu Fanjun is a subordinate general under Liu Bang, he was asked by Tian Rong to assist Tian Guang last year, and he is standing by Tian Guang's side at this moment. He looked carefully just now, the Han army ranger was probably killing his own fast horse from fifty paces away, and the range of the Han army's riding crossbow was about thirty steps, so it could be judged that it was a bow rather than a crossbow.

"With a bow?" Tian Guang's face was very unpleasant, the mainstream and main battle arms of the Han army have been changing, but the situation of the countries has been standing still, which is not a good phenomenon: "We can already shoot arrows on horseback, for us...... Not good news! ”

With stirrups, you can use your legs to get stronger, and a knight can free his hands by biting the reins, and he needs a good sense of balance to shoot arrows on horseback. In the era when there were no stirrups, archery on horseback has always been the patent of the Hu people, and the bow used by the Hu people could not be a strong bow, but a horn bow with poor range and lethality.

A horn bow made of animal horns and tendons is not a very good bow, it is a small bow, and the strongest lethality range is within ten steps, and the effective killing range will definitely not exceed thirty steps. And even if it is the strongest lethality range of the horn bow, when facing a soldier with metal armor, unless it can shoot a position without armor protection, it will be a life that will be bounced away at all; At the same time, the arrows fired by the corner bow within ten paces were aimed at the soldiers wearing leather armor, and at most they would shoot through the leather armor and slightly penetrate the flesh, and it would be a joke to form a fatal wound.

The horn bow will only have a strong lethality when dealing with soldiers without armor, but the range and lethality have always been hard wounds, such as the picture of being shot by the horn bow in the film and television, or the picture that the horn bow can be shot through, it is simply an exaggerated or "fantasy" way of filming, so the correct scene is that a Han soldier is like a hedgehog full of arrows, and before the Han soldier does not lose too much blood, he will fight vigorously.

"Can you see what type of bow the Han Army rangers use?" Tian Guang seems to take this issue very seriously.

Yu Fanjun naturally has no clairvoyance and no fiery eyes, he calculated in his heart that if he can kill a person with a shot from fifty steps away, then the strength of the bow is at least more than one stone, which should be the type of bow used by the infantry in terms of lethality. He was about to speak, but the Han army ranger who had shot and killed his fast horse leaned over, as if he wanted to show off his might?

Of course, the Han army rangers were showing off their strength, and their intention was to deter the Qi army in Picheng not to want to go out of the city at will.

This is not only Yu Fanjun, but Tian Guang can also look carefully, there is a holster on the side of the Han army's ranger war horse that can place bows, looking at those bows are larger than the bows used by the foot soldiers? (To be continued......)
