Cairo is different from Jerusalem because Cairo has a moat. So the besieging army had to cross the moat, unlike Jerusalem. All you need to do is fill the trenches!

Another difference is that Egypt is a powerful country in the Middle East. It is far from being comparable to Jerusalem, that is to say, when Yun Hao was besieging Cairo, he encountered enemy reinforcements.

The enemy reinforcements were fierce, wearing helmets made of stainless steel and chain mail woven from steel wires. The armament consisted of a strong bow, a spear, a sharp Damascus scimitar and a shield. The Mamluk strongbow is one size larger than the Turkic strongbow, has a long range, and has a strong penetrating power, but the rate of fire is slightly slower. The mount is a well-known Arabian thoroughbred, tall and long-legged, with impressive sprint speed and decent stamina.

The first time Yun Hao saw this cavalry, he knew that this was the Mamluk heavy cavalry that had made the Mongols tremble. Even Napoleon praised this cavalry, but he didn't expect to meet it in the Middle East.

The fighting power of the Mamluk army is second to none in the Arab world, due to the availability and training of soldiers. Every year, Arab traffickers abduct or abduct tens of thousands of children from the Caucasus and Central Asian steppes and send them to slave markets in Baghdad, Damascus, and Cairo for sale.

The Arab sultans selected the best quality children, bought them and sent them to military schools to become future Mamluk soldiers. The most popular Mamluk "raw materials" came from the Turkic tribes of Georgia and Central Asia in the Caucasus.

The mountain peoples of the Caucasus and the Turkic peoples of Central Asia have a strong physique and a brave and fierce character, which is an excellent material for serving as soldiers. For 500 years after the establishment of the Mamluk regime in Egypt, almost all Mamluk soldiers came from the Caucasus.

The Mamluk military school has a very scientific training system, where children first learn Arabic and teachings, instilling loyalty to their masters; At the age of fourteen, he began systematic training in physical and military skills, including proficiency in the use of weapons such as scimitars, spears, and bows, as well as basic horsemanship.

Archery is particularly highly valued, with students practising archery while standing on the ground, then learning to shoot on horseback, and finally learning archery on horseback. After mastering the basic military skills, the cadets began to receive the so-called "riding training", that is, the maneuver training of cavalry tactical units. Here, the trainees practice maintaining formation and taking care of each other in various tactical maneuvers such as advancing and retreating.

The Mamluk army combined the advantages of European knights and Central Asian light cavalry in terms of equipment and tactics, and the Mamluk soldiers were well-trained, disciplined, and tenacious. The Mamluk dynasty relied on this powerful army for more than five hundred years.

Yun Hao categorically rejected Cheng Chumo's idea of going to battle, Napoleon's favored army, Yun Hao didn't think Cheng Chumo would get benefits. And looking at the well-groomed ranks, the Mamluks were not easy to deal with.

Seeing that there were reinforcements, the drawbridge at the city gate was lowered. The Egyptian army began to fight back out of the city, believing that as long as the inside and outside should cooperate, they would definitely be able to defeat the Tang army. After all, there were no more than one or two thousand infantry blocking the gates of the city.

If they had enough knowledge of the Eight Bull Crossbow, they would never rush out so recklessly.

The moment the gates opened, the Egyptian army poured out like a tidal wave. And almost at the same time, the thick bolts of the gunpowder crossbow also flew into the crowd.

"Boom! Rumble! Rumble......! After a dozen explosions, the crowd seemed to crash on the reef and was smashed into countless waves. The cave in the gate was filled with mutilated corpses and the wails of the dying. The walls of the city gate cave were covered with minced meat almost instantly. The red whirring was sticky, and the broken bones were splashed everywhere.

On the top of the city gate hole, there is a strange thigh bone. The white bones were hung with plasma, and bone marrow oil was still dripping down the stubble drop by drop. The pungent smell of blood and gunsmoke mixed together to form another smell.

Such scenes were played out in almost every city gate, and the dense formation of the Egyptians resulted in huge casualties.

Some brave men, trampling on the mangled corpses under their feet, continued to attack. But the gunpowder crossbow arrows of the Tang people were replaced by fire oil crossbow arrows. Gunpowder crossbows are so valuable that the least valuable thing in the Middle East is actually fire oil.

More than a dozen fire oil crossbows rushed into the cave of the city gate, with a soft sound of "呑". The fire spread in an instant, and those brave people became fire men at once. Flames clinged to their armor and scorched their bodies. The pain was so intense that they immediately ran wildly over the corpse, as the corpse beneath their feet was also full of flames.

They tried to escape as quickly as possible, but most of them didn't get out of the gate until they died.

The fire oil crossbow was constantly fired, and the corpses were incredibly twitched by the flames. Large drops of corpse oil dripped into the flames, and the flames burned even more vigorously.

The billowing smoke makes this a living hell. The attack stopped in an instant, and no one dared or could get out of the city gates. The Egyptians' plans to cooperate with the outside world were bankrupt almost instantly. And there were only a dozen eight-ox crossbows in front of each city gate.

When one plan failed, the Egyptians took the rope down from the city wall. Some warriors, with scimitars in their mouths, climbed along the tall walls. It's a pity that these warriors became the target of the Eight Bull crossbow shooting. This time, the Eight Bull crossbow fired ordinary crossbow arrows.

Powerful crossbow bolts often pierced the chests of the warriors, nailing them to the walls. No matter how desperately they struggled, they couldn't get the bolts out of the crossbow bolts that were nailed deep inside the walls.

However, the crossbow bolts are not always accurate, and the speed of the wind, the judgment of the shooter, and the obscuration of smoke all affect the accuracy. Some were shot in the thigh with a thick crossbow arrow, and the thigh was shot in two at the root. Blood gushed down like a waterfall, and the screams of the warriors fell into the moat with the sound of whistles.

The Egyptians' solution was simple, drop more ropes and let more people climb down the ropes. You only have a dozen eight-bull crossbows, and you can only fire a dozen crossbow arrows at a time. Your thing isn't bursting, and it takes time to reload.

Soon the rate of fire of the eight-ox crossbow could not keep up with the speed at which the Egyptians climbed down the wall, despite the fact that there were many people nailed to the wall. There are more people who can climb down the city wall smoothly!

However, the Egyptians had a problem, that is, the moat that blocked the enemy's attack became an obstacle for them. If you want to go down the river, you have to take off your armor, and no one is stupid enough to jump down and swim in armor of dozens of pounds. That's not bravery, that's death!

When the number of Egyptians who arrived at the city increased, the eight-ox crossbow was immediately replaced with a fire oil crossbow. Thick crossbow arrows carried green smoke into the crowd below the city walls, and then orange flames rose into the air. Shrouded in huge black smoke, countless people with flames burning on their bodies jumped off the moat.

Even if you have infinite strength, you can wear dozens of pounds of armor and want to swim. That's absolutely impossible!

As soon as the people reached the moat, they began to sink, and those who could swim wanted to flutter twice. But people's physical strength can't resist gravity after all! Samurai in armor struggled under the water like a scale. After a while, they stopped moving.

Someone wanted to free his armor and jumped into the water. But the armor that can only be put on with the help of the servants is not easy to take off at this time.

Death always brings out the infinite potential of a person, and in the face of the flames of the crossbow arrows, there are still people who have accomplished this feat. They removed their armor and jumped into the moat with their cutlass in their mouths. Then he swam to the other side and charged forward despite his exhaustion.

As you can see from how fierce they are, these are all pawns. After swimming through the moat, you can still run like flying.

Once a person has crossed the moat, the eight-ox crossbow is left alone. Because Yun Hao left one or two thousand people, most of them were crossbowmen.

These people don't have any armor on them, but they have to face the most terrifying Tang Dynasty crossbow in the world. As long as the crossbow arrow is shot at the body, it can shoot a large living person in pairs. No matter how strong the physique is, it is forbidden to have more than two crossbow arrows piercing wounds.

The cavalry of the Don Army may be inferior to the Mamluk cavalry, but the crossbowmen of the Don Army are definitely the best. Yun Hao trained his soldiers, and he always gave priority to crossbow arrows. If you can't hit the target in the assessment, you can only eat steamed bun pickles. I can't see the meat star for a week, not everyone can stand it.

If you want to eat meat, you have to train hard, and after long-term training, almost all of the Tang soldiers have the ability to be marksmen.

These Egyptian warriors, though they were all fierce. But there was no armor on his body, and no one brought out the shield. Under the dense accumulation of crossbow arrows, he could only fall on the way to charge with hatred.

The Egyptians were saddened to find that the soldiers, who had climbed down the rope, had found themselves in a disadvantageous situation from the very beginning. The outstanding soldiers could only glance at the Tang army's military formation with hatred, and then fell in a pool of blood and returned to heaven.

Not a single person was able to rush to the front of the Tang army and engage in a white-knuckle battle with the Tang army. Those guys with gunpowder on their backs exploded under the scorching flames, and finally a skeleton remained.

The generals of the Egyptian army sadly found that their men were only playing the role of wasting the crossbow arrows and fire oil arrows of the Don army. God knows how many of these things there are in the Tang Army, anyway, before his army is consumed, he will definitely not be able to consume all the materials of the Tang Army.

Almost as soon as the attack was launched inside the city, the Mamluk cavalry also began to charge.

Their charge was very characteristic of the nomads, the skirmish line was drawn wide, and the men were bowed low on horseback. At first glance, he is a guy who has been practicing equestrianism all year round, and he has basically achieved the unity of man and horse.

With them in the vanguard, behind them were the Egyptian infantry that swooped down like waves. It was no longer clear how many infantry there were, and the smoke and dust in the sky obscured the view. It's just the dull sound of footsteps, which makes people wonder if it's an earthquake.

"Rockets, elevation three, covering shot!" Seeing the Mamluk cavalry rushing past the rangefinder stone, Sheng Yanshi shouted. Behind him, the characteristic "whoosh" and "whoosh" sound of rocket artillery firing sounded.

Countless rockets shot into the sky in the thick of smoke, and then the smoke from their tails streaked in a trail and fell into the charging formation of the Egyptian infantry.

The characteristic of rockets is that the accuracy is terrible. However, it is very easy to deal with large-scale targets. Especially in this state of volley, a covering shot is simply a nightmare for any surface creature.

The dull sound of explosions came one after another, and there was smoke everywhere, and it was not clear what it was like on the battlefield. Yun Hao still sweated in his heart, in case this was a trick by the Egyptians to lure the enemy, he would have to face the white-knuckle battle that he was most unwilling to face.

"Trebuchet launch!" Seeing the Mamluk cavalry passing through the second rangefinder stone, the trebuchet fired. It's still a fire oil bomb, and there are really not many gunpowder bombs in Yun Hao's hand. As a last resort, oil bombs have become the best choice.

Hundreds of oil bombs flew towards the enemy position in smoke, and the orange flames even connected the city with a wall of fire. Many Mamluk cavalrymen came out of the walls of fire with flames on their bodies.

The sharp tip of the knife pointed in the direction of the Tang Army's military formation with flames, and it still charged.

"Eight bull crossbows, gunpowder bullets. Two hundred at a distance, launch! "There's no way, Yun Hao can only use a gunpowder crossbow at this distance.

A loud explosion rang out, and countless shelmels tore apart the armor of the Mamluk cavalry. Under the back, the Mamluk cavalry that rushed out of the smoke was less than 400 people.

"It's really tough!" Yun Hao saw that those Mamluk cavalrymen had already taken off their bows and arrows, and threw their bows and arrows far away with the speed of their horses.

However, this kind of projectile was not very lethal to the Tang army, and most of them were blocked by people with shields. Even if they didn't block it, the armor on their bodies protected them well. Even if someone is injured, it is not too serious. As for those who were shot, it can only be said that the sword has no eyes on the battlefield.

"A hundred distances, crossbowmen fire!" Despite the blockades, the strong Mamluk cavalry rushed forward. But they were greeted by arrows like a rainstorm. Tens of thousands of crossbowmen fired together, and the sunlight dimmed.

Yun Hao was surprised to find that under such a rain of arrows, there were still Mamluk cavalry rushing over. Although the number is only about a hundred, the ferocity of their charge still makes people's hearts palpitate.

The men were covered in arrows and armed with bloody Damascus steel knives. The snowflake pattern is shining in the sunny mountains!

"Cheng Chumo, use your sword to fight for your honor. Today's glory belongs to you! Yun Hao patted Cheng Chumo's shoulder.

Cheng Chumo's nose was almost crooked, and he had 5,000 cavalry under his command. Go and kill a hundred people, and say it's a glorious thing.

However, a military order is a military order, and Cheng Chumo urged the war horse under his crotch. Straightened up, the horse lance rushed out first!
