The large number of crossbow arrows thrown by the defenders did not cause much damage to the attacking enemy, but they played a deterrent role and made them feel pressure, in addition, the poorly protected river reclamation soldiers were attacked more, and the number of casualties was much more than that of the crossbowmen, and once the people were injured, they had to withdraw from the battle, which meant that the combat effectiveness was reduced by one point.

Under the command of Qi Yad, the army is still moving forward, and a little loss in the eyes of the generals is simply a trivial matter, especially the fierce generals who have fought a big battle, they have long been accustomed to seeing the scene of corpses all over the field, and they will not feel much when they see the soldiers under their command killed, not to mention the injuries, what the generals need is victory, a victory that will completely defeat the enemy, as long as the war can be won, it is worth sacrificing how many soldiers are sacrificed, so there is a common saying that a general will succeed and ten thousand bones will wither.

Ziade's eyes were always staring at the city wall in front of him, he was thinking about how to break the city, not how many people would be sacrificed to break through the city, he had already seen the first round of the enemy's counterattack, what tricks would the enemy have next? He was still waiting, waiting for more of the enemy's defensive moves.

When the first row of giant shield soldiers reached the edge of the moat, all the soldiers and horses responsible for covering were already in place, the giant shield soldiers and the shield soldiers in the back rows were responsible for covering, and the large number of crossbowmen who hid their bodies behind them released arrows into the wall through the gap to suppress the soldiers on the wall and cover their own soldiers transporting sandbags.

This trick is often used by the besieging party, the effect is naturally there, the soldiers defending the city in order not to be shot by arrows, naturally need to dodge, the attack is not as random as before, the frequency of attack is greatly reduced, however, the projectile is still better, because the projectile is a probability to kill the enemy, and there is no need to aim and shoot, as long as you roughly know the enemy's location, you can completely hide behind the city wall and shoot.

After the enemy approaches, the effect of the projectile attack is naturally not as good as the direct shooting effect, so in order to better kill the besieging soldiers, the defending soldiers risk leaning out of the female wall and attacking the siege crossbowmen exposed from the gaps in the shields, of course, including the river fillers who transport sacks, especially the river fillers, are the top priority of the defender's attack, because once the moat is filled, the defender loses a very good defensive trench, which is very disadvantageous for the defender.

The attacker's position is relatively low, and the crossbowmen on the city wall are in a higher position, and the female wall of defense is much stronger than the giant shield in terms of defense, so the defending side has an advantage in the shooting, and the attacking side will suffer a lot.

For this reason, the attacking side also prepared a sharp weapon for shooting, that is, a mobile arrow tower higher than the city wall, this mobile arrow tower needs to be pushed by many people, the front and sides are all covered by wooden boards, the top design is similar to the female wall of the city wall, and the overall height is often higher than the city wall.

In this way, when firing at each other, the attacker will not suffer, and Ziyad's army also has this kind of large weapon, and participated in this siege operation.

Because of the urgency of time, only the frontal attacking soldiers and horses had four large mobile arrow towers, and they had already moved up and were soon in place.

With condescending archers, the advantage of suppressing the defenders of the city wall is more obvious, and soon the new defenders on the city wall are suppressed and dare not show their heads, and they have no choice but to mobilize more crossbowmen to shoot at the besieging soldiers on the mobile arrow tower.

As a result, the defending side will not have enough firepower to deal with the reclaimed soldiers, which will directly lead to a significant increase in the progress of the reclaimed soldiers.

This situation is obviously more powerful for the attacker, as long as the attacker fills in the moat, a large number of soldiers and horses can get close to the city wall, and immediately launch a fierce attack on the city wall, and it is not difficult to break the city in one fell swoop.

Aibu ***, who was watching the battle from a distance, smiled disdainfully, the combat strength of the defender was already in his eyes, he felt that the strength of the defender was really not good, at least, much worse than the soldiers and horses under his command, and a random wave of attack was a little unbearable, a large number of defending soldiers were afraid of sacrifice, and they were hiding behind the female wall, such soldiers and horses were too weak, at least, in the eyes of Abu ***, the defensive soldiers and horses were indeed relatively weak, therefore, he was full of confidence in breaking through the city, and felt that he would be able to break through the city.

Ziyad also saw the fact that most of the defending soldiers were new recruits, and only needed to look at the performance of the defending soldiers to see their level.

However, the defenders have a lot of defenses, and at the moment they don't only have heavy crossbow attacks, they have many other defenses.

For example, during the attack, the attacker attacked the city wall with a large number of catapults, causing certain casualties to the defending soldiers on the city wall, and the attack of the catapults continued, so that as the defending side, it was natural to use the catapults to counterattack.

The catapults for defending the city supported by the Tang Dynasty were deployed in Archeng, these catapults for defense were more compact in size, and could be well equipped on the city wall, used to fight the siege of soldiers and horses, compared to the bow and arrow projectile, the power of the projection vehicle projectile was obviously much greater, after all, the weight of the bow and arrow was very limited, and the power of the attack was not large enough, and the catapult could project very heavy stones onto the soldier's body, which could cause greater damage to the soldier, especially the condescending projection, and the power was increased a lot.

Of course, in addition to the catapult, they were also equipped with bed crossbows, which were far more powerful than the heavy crossbows in the hands of soldiers, and were a killer weapon for defending cities, because bed crossbows had an extremely high range, much longer than the range of heavy crossbows.

However, whether it is a catapult defending the city or a bed crossbow, the number is relatively rare, after all, these are all sold to Artik by the Tang Empire, and it is difficult for them to imitate them on a large scale in a short period of time, in addition, there are some production processes in this, they may not be able to learn, even if they can imitate the same product, the estimated range and power will be greatly reduced.

The generals defending the city did not dare to show their heads when they saw a large number of recruits, no matter how they reprimanded, it did not have much effect, and the enemy river fillers under the city were going all out to fill the moat, which was very unfavorable to the defending side.

The catapult's attack accuracy is not very high, but the siege party's mobile arrow tower is densely packed with soldiers, including shield soldiers and crossbowmen, so even if the stone does not hit the moving arrow tower, it will still cause great damage to the soldiers around it.

The bed crossbow also reangles and aims at the mobile arrow tower outside the city.

The attack of the catapult was unfolded first, and the stones were thrown at the moving arrow tower, because the accuracy was not high, so most of them fell below, and the most were smashed on the shield, the shields were made of wood, and the defense was not very strong, and there would be no problem in resisting the rain of arrows, but if it was a heavy stone, the shield would not be able to resist, even if it was a huge shield with a lot of thickness, when facing a large stone thrown from a high altitude, it was not uncommon to have little resistance, and it was not uncommon to be smashed.

A small number of stones smashed a lot of shields, and also injured a lot of siege soldiers, and a small number of stones smashed on the mobile arrow tower, smashing the defensive planks in the front of the arrow tower.

One of the reasons why the mobile arrow tower has an advantage is that it is higher than the city wall, and the soldiers on it can shoot from a high position, and the other reason is that the mobile arrow tower has a relatively thick wooden plank on the front, which is enough to block the attack of the defenders' arrows, thus protecting the safety of their crossbowmen.

This mobile arrow tower, which has a very nice name in the Chinese Empire called Jing Yan, is a very useful siege weapon, which was transmitted to the Arab world a long time ago, because this siege weapon has no technical difficulties, as long as it looks the same, it can be used, and it will not be like a slightly technical weapon like a bow and crossbow, which is useless to do, and the power and range are different.

After the defensive planks on the top of the mobile arrow tower were smashed, the crossbowmen inside were miserable, their bodies completely exposed to the crossbows of the soldiers defending the city, and after a few rounds of attacks, the crossbowmen of the besieging side suffered a large number of casualties.

The use of mobile turrets was originally intended to reduce casualties and suppress the defenders, but as a result, the shield was destroyed and the soldiers had no cover, so the mobile turret had to withdraw from the battle.

During the retreat, one of the mobile arrow towers was hit several times, and the wooden frame in the middle was broken, which caused the mobile arrow tower to collapse and killed a large number of soldiers.

Seeing this scene in front of him, Qi Yade, who was in charge of the command, was greatly surprised, the other party's catapult attack was too accurate! It's too powerful, isn't it? It was much more powerful than he had imagined.

Indeed, the catapults supporting the city defense by Datang are relatively powerful in terms of accuracy and power, so it can be easier to destroy all kinds of weapons on the besieging side.

"It was destroyed not long after it went up, how is this possible."

Qi Yad didn't believe in evil, and ran forward from the side, he wanted to take a step ahead to see what kind of attack it was, and he could beat his mobile arrow tower and couldn't continue to fight.

Of course, for his own safety, Ziyad would not get too close to the city wall, at least one and a half times the range of the opponent's crossbow, so that it would be a safe distance.

Three of the four mobile turrets have been withdrawn, and one has been completely damaged, leaving it on the battlefield.

Ziyad waited from a safe distance, waiting for the three moving arrow towers that were slowly evacuating, and this scene was naturally seen by the defender's generals.

The clothes worn by generals in different positions are different, and Qi Yade's clothing is obviously different from that of ordinary generals, so as soon as he appeared, he attracted the attention of many soldiers on the city wall.

"Here comes a big fish, all the bed crossbows are ready to shoot, aimed at the enemy commander."

Many of the bed crossbows were all angled and aimed at Ziyad in the distance, if they could kill Ziyad in one fell swoop, then it would be a very huge victory for the defenders, and a disaster for the besiegers.

Ziyad obviously would not have imagined that a large number of bed crossbows defending the city wall had been aimed at him, and he would not have thought that the range of the bed crossbows was enough to cover the position he was in, that is, the position he was in now was not safe, but a very dangerous place.

As soon as all the bed crossbows were ready, a salvo came and the target was Ziyad in the distance.

"Whoosh ......"

A large number of crossbow arrows grazed his ears, which made Ziyad take a big jump, and he didn't have time to think about it, so he immediately leaned down to dodge the incoming crossbow arrows. Many of the guards around him were shot by the crossbow arrows, and the huge inertia caused the bodies of these guards to fly a long distance.

A huge bed bolt was lucky enough to concentrate Ziyard's mount, and he almost missed him in the thigh, but as the horse fell to the ground with a bang, Ziyad fell heavily to the ground, and fell to all fours, looking rather embarrassed.

Fortunately, Ziad had been in battle for a long time, and reacted very quickly, hiding behind the carcasses of the horses, not caring about anything that was not imaged, if he lost his life, everything would be over.

Ziyad declined from the horse, and this scene was seen by Abu *** in the rear, as well as the defending soldiers on the city wall, and the defending soldiers were naturally very excited when they saw Ziyad fall off their horses, while Abu *** was greatly shocked.

After all, Ziad is his right-hand man, and if Ziyad has any three strengths and two shortcomings, it is equivalent to him losing his arm.

Because of the long distance, Abu *** didn't know what happened to Ziyad, but he was sitting in the back, and he couldn't run over to see it himself, otherwise, if even he was in danger, the consequences would be even more serious.

Ziyad was not injured, but because the opponent's bed crossbow bolt had been shooting, he didn't dare to get up rashly, in case he was shot, the game would be over.

Soon, a large number of guards behind rushed over with a large number of shields, blocking in front of Qi Yade, forming multiple lines of defense in front, and Qi Yad finally retreated in embarrassment under the protection of the guards, and even dared not ride a horse.

The war horse that was shot to death was a very valuable horse, and it was also a comrade-in-arms who had been with Qi Yade for many years, and he was shot and killed like this, Qi Yade's heart was somewhat uncomfortable, but the war horses were already dead, and it was useless to be sad, and accepting reality was the only way.

As he was leaving, Ziyad pulled out a crossbow bolt, which was the first time he had seen such a large crossbow bolt, and he was amazed.

Abu *** in the rear saw that Ziyad was not in big trouble, and he was greatly relieved, fortunately his right-hand man was fine, otherwise, once Ziyad was killed, it would be a serious blow to the morale of the army.
