Of the first batch of 50 heavy cavalry who crossed the low wall, more than 30 fell to the ground, and another dozen or so jumped over the obstacle safely because of luck or because the horses reacted quickly enough and were able to continue running.

But being able to keep running and how far you can run are two different things.

After running for more than fifty meters, through the thin smoke that spread all over the field, a long crater appeared in front of him.

In fact, this long pit is not deep, it is only about one meter deep, seven or eight meters long. The width is just stuck on the side of the mountain at both ends, about more than 100 meters wide.

Anyway, if you want to get there, you have to go down to the pit like crossing a river, and then go up again to the opposite bank ten meters away.

This long pit was set up by Ho Tai Sin according to the idea of the tank trench invented by the Israeli army in later generations.

For heavy cavalry, such a deep pit could not be rushed. After all, the war horses of the heavy cavalry need to carry a load of nearly 200 catties, and jumping into a pit with a depth of one meter can easily break the horse's legs, so they can only dismount and lead the horse. For the light cavalry, although it is possible to cross the pit directly without dismounting, it is also necessary to slow down to get down the pit safely, and after going down to the bottom of the pit, the bottom of the pit is only ten meters long, there is no room for running, and you can only climb up slowly when you reach the opposite bank.

He Daxian thought very clearly in his heart, the Tang army was expected to deal with about 5,000 Khitan cavalry this time, and it was unrealistic to trap so many cavalry simply by trapping.

So the first low wall just gave the Khitans a dismount, and by the way, some heavy cavalry were killed. And what is really used to block the Khitans starts from this long pit.

The first Khitans to rush through the city gate were one hundred and six heavy cavalry (after deducting the nine horsemen who fell at the city gate) and two hundred light cavalry. The first batch of heavy cavalry who crossed the low wall fell more than 30 horses, the second group fell more than 20 horses, and finally only 42 heavy cavalry came to the side of the long pit, except for three unbelieving fools who jumped directly and fell half to death, the rest quickly stopped their horses, waiting for the light cavalry behind to go to the front to open the way.

Two hundred light cavalry also fell at the low wall for more than thirty horses before running one after another, but fortunately the light cavalry reacted quickly, and the others either carefully slowed down over the wall or went around directly from both sides.

This is the problem of the "leader" who does not like to take the lead, the leader ignores him, and there will inevitably be problems in communication between his subordinates. But it's too late to say anything at this time, the most important thing is that before I saw the Tang army, my own people had already lost nearly a hundred horses, and all the Khitan cavalry had nowhere to vent with a fire in their hearts.

The light cavalry ran to the edge of the long pit, and saw more than forty heavy cavalry cowering and gathered beside the long pit and did not dare to pass, and the hundred leaders of the light cavalry hurriedly shouted: "The heavy cavalry in front is scattered!" Disperse! Then he took his men and jumped down to the bottom of the pit one meter deep, one after another, like dumplings, and then pulled up the horse's head from the other side of the pit and climbed up.

At this moment, the first batch of one hundred Tang Army archers emerged from a trench a hundred paces away, that is, seventy or eighty meters away.

"Group A ready, three, two, one, shoot!"

With a buzz, a hundred feathered arrows overwhelmingly covered the dozens of Khitan light cavalry who had just climbed up from the bottom of the pit!

This is something that has never been seen in this era, and He Daxian set up a trench warfare method according to the idea of the First World War on Earth.

The archers of the Tang army, like the riflemen of later generations, hid in pre-dug trenches. These trenches are connected to each other, and once they fail, they can immediately move on to the next trench to form an effective depth and implement a three-dimensional defense layer by layer.

It was not very difficult for five hundred archers to defend a frontage a hundred meters wide.

He Daxian is well versed in the way of cavalry, once the cavalry loses its speed advantage, it is a huge target. At this time, for the archers of the Tang Army, the Khitan light cavalry in front of them, who had just climbed up from the pit or were climbing up from the pit, had a large overlapping volume of people and horses, and they were basically in a static state, which was too easy to shoot.

Under the shadow of the rain of arrows, the first batch of more than 50 Khitan light cavalry who climbed up, hula people turned over on their backs, and directly fell more than 30 horses, some of them were hit by arrows, and some of them were hit by arrows, anyway, for cavalry, whether it was an arrow in a person or an arrow in a horse, this set of cavalry was wasted.

"Group B ready, three, two, one, shoot!"

The second round of 100 arrows was fired, and a large number of the remaining dozen horsemen and the twenty or so horsemen who climbed up behind them were knocked down.

The third round of arrows was fired silently, with only a dozen arrows. This is Wang Dazhui and Shan Wu with twelve elite shooters composed of a "fart sniper team", precise point-to-point, P2P, the remaining seven or eight fish that have not been hit by the arrow are killed one by one.

Suddenly attacked by the Tang army's arrow rain, the entire Changkeng and both sides of the Changkeng began to be chaotic.

The light cavalry who came from behind continued to jump into the pit, and the people who were already in the pit and were about to go ashore saw that the big brothers who had gone ashore in front of them fell to the ground, where did they dare to go up again, for a while there were more and more people in the pit, everyone squeezed around, some people shouted "rush", some people shouted "retreat", and then scolded, and a small number of small leaders with a sense of justice had begun to cut down those guys who retreated.

"Group A extends, prepares, three, two, one, shoots!"

This round of arrows was an extended shot and went to the bottom of the pit.

There was a crackling arrow, and the chaotic people at the bottom of the pit suddenly screamed, and the injured and uninjured pushed me to let me, and the signs of trampling on each other began to appear.

"Group B Extend, Prepare, Three, Two, One, Shoot!"

Another rain of arrows shot directly at the bottom of the pit, causing chaos again, and some of the quasi-heads were almost shot directly to the opposite side of the long pit!

On the other side of the city wall of Shenchi Pass, seeing that a hundred heavy cavalry and two hundred light cavalry had successfully entered the city gate, Jeruzachel turned his head and glanced coldly at the little general Wu Lizhen.

There is no way around this, there are more than 300 people in front, and if you, the "leader", do not move, then it is no wonder that the "big leader" may be unhappy.

Now this situation is a typical "big leader" with a "little general" and a team of 1,000 people out to fight, if not to charge together, then the customary custom is to divide into two teams of 500 people, the original 1,000-man "little general" to lead a team, and the "big leader" to lead a team.

Now that there are 300 people rushing out in front, then, do you say that those 300 people are counted among the 500 people brought by your "little general"? Or do you count the 500 people brought by my "big leader"?

Jeruzachel was a great leader.

When encountering a petty official like Wu Lizhen, who is greedy for life and afraid of death, and likes to hide behind the soldiers and put up a leadership shelf, the way to deal with him is also very simple, that is, to put a bigger shelf than him.

Although Wu Lizhen is also covered by someone, in the face of the "Ten Khitan Heroes" like Yelu Saqi, where can he dare to hold on again. This is a front-line battlefield, if you really cut Jeruzah in a hurry, people will not tell you a word of nonsense, just a big pineapple smashed down, and you will die in vain.

Wu Lizhen had no choice but to wave his hand and pick up the remaining two hundred light cavalry, and rushed in through the city gate in a puff of smoke.

As soon as she rushed into the city gate, Wu Lizhen immediately felt that something was wrong.

There is a low wall in front of it, and the smoke is not very clear, but it vaguely seems to be a person turning on his back, and the vision is even more blurred in the farther away.

Ulizhen slowed down in time and waved his hand to give the command to charge.

"Wow!"

The two hundred light cavalry behind them sped up, and the fast horses overtook their commander, who was running slower and slower, and rushed towards the low wall at the highest speed they could!

"Wow!"

"Wow!"

"Wow!"

"Wow rub! Ahh

"Ahh

When all the light cavalry behind him surpassed him, Wu Lizhen ran to the edge of the small low wall, and saw that the two hundred light cavalry that followed him just now, more than one hundred and twenty horsemen fell fiercely behind the low wall, and the other light and heavy cavalry that fell before were stacked into a pile of meat, and the whole low wall was full of stumps and broken arms, dripping with blood, and the desolate cry sounded into a terrible scene!

However, you don't see any enemies, huh?

Farther ahead, there were many figures, shouts of murder and screams through layers of light mist.

Wu Lizhen didn't pay attention to the wounded soldiers behind the small low wall for the time being, and rushed forward with the remaining seventy or so light cavalry that had not fallen just now.
