Before dawn the next day, the soldiers of the Tang army got up to make a meal, ate a round belly, and then marched for about two hours to arrive near Heisha City, just when they were not full or hungry, it was a good time to fight. The 10,000 Tang Army was divided into five prefectures (departments) under the command of five middle-level generals, and the regiment was set up two miles south of Heisha City. The Turks were also prepared, and from a distance, they could vaguely see their cavalry on both sides of the city. The two sides were ready to fight again.

After observing the enemy's arrangement, Du Xian said to his generals: "The purpose of the Turkic cavalry is to deal with the defenders, and they will not fight to the death with our army, and it may not be easy to eat them first and then attack the city; The besieging city was understaffed. The only way to do this is to seize the fortifications of Black Sand City first, leaving its cavalry with nothing to rely on. ”

The staff reminded: "It is reported that the Xianbei people also used the general's current strategy, but they failed to achieve results in the face of pressure from three sides. ”

Du Xian said with a smile: "The Xianbei people are not good at attacking cities, and even if my Tang army is a horse team, it can let the Turks see and understand." ”

The tactical plan was agreed that Du Siam would not delay, and immediately ordered to prepare for the siege. He is white-skinned and fat, and he has an elegant style, but the commander is neat and neat, which is no different from the style of a military general, and all the generals are obedient.

Later, Du Xian agreed with the generals of each department to command the signal, and used three musical instruments, drums, trumpets, and gold, and the different rhythms corresponded to different horse teams. Although it can only be used for short-distance advance and exit signals, the advantage is that it is more rapid and timely. Of course, if it is a more complicated military order, you can only send someone to inform the generals.

The battlefield is pitted against each other, but like the darkness before dawn, the hustle and bustle is extra peaceful. The camp saw people running back and forth, and the neighing of the horses was mixed with the shouts of the generals, just like the school field for training on weekdays, there was no blood and no fire. Du Xian finished explaining some detailed rules to the subordinates below, was silent for a moment and then said: "There are not many opportunities to attack the grassland from afar, and I hope that you will cherish the fighters on the blood debt of the people in various parts of the border and fight bravely to kill the enemy!" ”

He didn't hiss, tried his best to make a generous statement, but just said such a sentence lightly, which ignited the feelings of the generals, and suddenly the generals were in an uproar, and they all clapped their chests and raised their arms to give the Turks a look.

Seeing this, a civil official took the opportunity to fan the flames: "Since the Wu Zhou Dynasty, the first time the Mosi Khan plundered Hebei and other places, 90,000 people were killed and wounded, and the displaced people were killed, wounded, and displaced. ”

In the noise, some people shouted to kill the enemy and serve the country, and the morale of everyone was high with hatred. Du Xian drew his sword and shouted: "Wherever the light goes, destroy the barbarians and the darkness." Let's go! ”

The whole army then advanced forward and crossed the Wujia River, and Du Xian was brave with his general Fan Shuhu, so he ordered him to kill the city with his troops as the vanguard, so as to win the opportunity for the siege troops behind.

The Tang army forward rode his horse and rushed straight to the south gate, and also saved the Turkic cavalry to lure the enemy, and the Turkic men and horses attacked the Tang army's forward from the east and west sides according to law.

The ballistas and stone-throwing carts in the city also began to fire flaming fireball rockets, and for a moment the flames were full of smoke. The cavalry rushed together, and the swords danced in unison, and blood splattered. The whole city of Black Sand was once again in a torment of blood and fire.

With the barrier of the left and right flank cavalry, Fan Shuhu's troops rushed to the city, charging back and forth, riding and shooting, the rockets on the city were also like a rain of fire, the forward personnel were not killed or injured, but the horses lost a lot, and even Fan Shuhu's mount was hit by an arrow and fell to the ground. As soon as he got up from the ground, there was a few clanging on his helmet, but luckily the arrow didn't shoot through the iron helmet. Fan Shuhu was furious, drew his knife and swung it a few times, but unfortunately the Turkic soldiers were out of reach on the city wall, and he opened his mouth in a hurry and said, "He|mother|", took the knife and slashed a few times on the earthen wall, and the sand splashed for a while.

Obviously, it was tragic for the cavalry to attack the city without siege equipment, and the Turks saw the Tang cavalry blocking the city, thinking that they were going to use shovels to dig the corners of the wall. This method is also feasible if you really have to sacrifice the cost and time, and the Turkic and other nomadic cavalry sometimes use this method when they are determined to break through the Han city.

At this moment, another group of Tang soldiers came up behind Fan Shuhu's department, those people were sword and shield infantry composed of abandoned horses, the group of men and horses marched to the city with cavalry armor and iron shields in a regimental phalanx, arrows could not pose a threat to it at all, and the accuracy of ballistas and catapults was completely insufficient and could only be fought indiscriminately, especially the Turks were not good at using these things, and they did not use much after learning to make zuò from the craftsmen of the Tang Dynasty, so they could only let the infantry calmly attack under the city wall. Occasionally, a fireball was thrown into the crowd of Tang Army's infantry, and the soldiers who were on fire screamed and rolled on the ground, and the horsemen between the regiments and camps hurriedly went up with wet quilts to rescue each other, and the attacking queue did not stop for a moment.

There are also small carts in the middle of the sword and shield soldiers, which are estimated to be temporarily assembled and are very different from the chariots commonly used by the Tang people, and the Turkic soldiers in the city have not figured out what they are used for, so the small carts are obviously not ladders or siege vehicles. The car was surrounded by heavily armored sword and shield infantry troops, only the stone-throwing vehicle could hit those cars, but unfortunately the stone-throwing vehicle had a long range but was not accurate, a fireball was thrown down from the wall one after another, and only a blind cat touched the dead mouse and happened to fall on the Tang army's chariot, but it was immediately ejected away. It turned out that the roof of the car was covered with hard cowhide, which was not good for sharp weapons, but it was full of elasticity against things like stone fireballs, and it bounced off as soon as it touched it.

At this time, the city of Black Sand is really lively, arrows and fireballs are flying in the air, horses are running, drums are beating the iron man-like sword and shield infantry "Kuang Kuang" as if in a training queue, the sound of trumpets and drums, shouting and killing sounds, and fireworks are rising on the grassland.

At the head of the Black Sand City, the Turkic Zuoxian King Tun Yugu couldn't help but ask Li Shizhi: "What are those chariots in the middle of the infantry army going to do?" ”

Li Shizhi had observed it for a long time before, and he didn't quite understand what it was for, and the siege was too small. Li Shizhi avoided talking about that thing and said: "This team of centaurs is elite, and I didn't see soldiers with such good armor when I was in the border three cities. Looking at the left and right flanks, the Turkic cavalry was twice as large as theirs, and they took less than half a cent of advantage, so that the Tang army in the middle of the siege could calmly attack the city without pressure...... With a fortification like Heisha City, it is not as good as even a state government in the Tang Dynasty, it is obviously not easy to block the Tang army from attacking the city, no matter what the car is for, if the middle road is allowed to go on like this, they can dig a gap in the wall even if they dig it with a shovel! ”

Tunyugu also nodded, and said to the little khan Toxi: "Focus on the cavalry on the left and right flanks, if there is no progress, it will be impossible for us to defend the city with just one wall." ”

Tosi suddenly remembered that the grandson of Tunyugu had a reputation as a Turkic warrior and was very brave, so he said: "Why don't you let Ketler lead the troops to rush for a while, there are few Tang soldiers, as long as you can break through the formation once, there is hope." ”

They discussed for a moment, and then ordered Zuoxian, the grandson of the Tunyu Valley, to lead a group of elite cavalry out of the city from the north of the city to reinforce the left flank. When he looked back at the city wall with a full of excitement, he did not find the princess Ashinad, she should not run to the city head when this kind of army was in chaos, but she still couldn't help but feel a little lost in his heart.

The Turkic troops rushed to the east wall of the Turkic left flank, and saw that the two armies were rushing back and forth on the battlefield without progress, and the Turkic soldiers launched a fierce charge from time to time, but the Tang cavalry did not move at all and directly repelled them. Qi Tler found the Turkic generals present and said: "After a while, the warriors of our Lust Valley tribe will break through the Tang army camp from the middle, you will follow and tear the rift and disrupt their formation, and the Tang people will retreat." The Turkic generals received another order from the little khan to reorganize an attack according to the plan of the Titler.

As soon as the horn sounded, Hitler rode his horse and led a group of wolf-like warriors to the front, and the Turkic cavalry shouted and swarmed up, and the scimitars flashed in the air. The Tang army on the opposite side did not retreat, but advanced, and rushed forward head-on. The horses on both sides galloped at the speed of a charge, and the lightning and flint met in short quarters. He is experienced in such tactics, and easily dodges the attack with his skillful equestrian skills, and the moment the two horses approached, he slashed with a knife, and there was a loud "bang" on the ground, and only saw a flash of sparks in front of him, and he only felt numb in his mouth, no different from a knife on a stone, and he didn't know if the blade was rolled, and he was stunned, and most of the confident mood at first had dissipated: Can this Ni Niang's armor be hard like this?

The knight who passed by Hitler could no longer turn back, and stabbed directly at the second rushing Turkic warrior, the hard leather armor on the Turk could not stop the assassination of the horse lance with the impact of the war horse, and the long soldier suddenly pierced through the chest of the Turkic soldier, and the ice blade was exposed from the back, and blood splashed. The horse lance was too long to pull out for a while, and the Tang army knight immediately gave up the horse lance, pulled out his horizontal knife and rushed into the Turkic crowd to fight. The soldiers of the two armies around them quickly stuck together, roaring and slashing and stabbing indiscriminately. The prediction of what directly penetrated the Tang Army's camp was completely unrealized, and the battle was clear in an instant, and it was still like that to fight together.

The elite soldiers of the tribe around Ketler were brave and good at fighting, the battle situation was not bad, there were casualties on both sides, and other places were not optimistic, the Turkic soldiers were desperately killed and wounded, and a general shouted in Turkic language: "Let's withdraw, retreat to the city and have ballista arrows to help!" ”G
