The rangers sent by Yelu Yuyin did not disappoint him, and the scouts of the army quickly extended their vision to ten miles away, and it was precisely because of this that Yelu Yuyin was able to get news of reinforcements from Yannan Yelu Naer and Yingzhou.

However, the good times did not last long, and when the scouts of the Khitan army continued to expand their horizons, they were counterattacked by the scouts of the Tang army with unprecedented strength. A large number of elite scouts sent by Yelu Yuyin, those with the strongest combat power under his command, were soon killed again, and they were crushed, and those who fled back with injuries were all three souls and two souls. Just by looking at the appearance of these rangers, Yelu could imagine what kind of nightmare they had just experienced.

In the end, the Tang army limited the vision of the Khitan scouts to within ten miles.

Ten miles is a very particular range. For the general army coming, it is necessary to ensure a normal march, and the scouts are barely enough to be ten miles away, and in the face of emergencies, they can also have about the time to form a formation to protect themselves. However, with a ten-mile vision, self-protection is acceptable, but enterprising is insufficient.

The scouts of the Hundred Battles Army entered the boundary of ten miles, which could also ensure that they would not be chased and killed by the cavalry of the Khitan brigade, and that they would have enough time to respond, and at the same time, they could also grasp the whereabouts of the Khitan army. As for the scouts of the Hundred Battles Army, the most important point of their actions was that they cut off Yelu Xiangyin from Yannan and Yingzhou reinforcements.

This is the important function that the scouts of the Hundred Battles Army can play on the battlefield in cooperation with the Military Intelligence Department. In other words, this is also Li Congjing's way of fighting.

After the field of vision was restricted, the Khitan army's marching speed had to slow down, because the front was unknown, so it had to be careful and march cautiously. Yelu was so angry that he almost beheaded his scout general, but under the persuasion of everyone, he agreed to let the other party make meritorious service and regain his vision.

Originally, it only took half a day to reach Yannan, but Yelu wanted to hide for a whole day and couldn't finish it. It wasn't until here at night, at the cost of the life of the scout general under his command, that the Khitan army rangers advanced a little, and Yelu Yuyin finally learned about the reinforcements from Yingzhou for the second time.

Starting from Yingzhou City, nearly 10,000 troops from the west to aid Yannan were ambushed by the Tang Army, and the battle was defeated, and the remnants of the army retreated to Yingzhou!

"Ambushed by the enemy at the door of his own house, what kind of fool did Kuchi also send over?!" Jerod was so angry that he kicked the messenger over and roared in the tent.

"The Tang army scouts are everywhere, the army rangers are all out and behind, and we don't know anything about the surrounding situation...... In addition, coupled with Yelunaer's urgency, the army fell into the trap of the Tang army......"

"Scouts again, damn it!" Yelu wanted to hide the blue tendons on his forehead, "There are Tang army scouts everywhere, could it be that Li Congjing's scouts all fell from the sky!" ”

Yannan, the camp of the Hundred Battles Army.

Compared with Yelu wanting to hide, Li Congjing learned the news that Li Shaocheng had defeated the Khitan reinforcements in Yingzhou much earlier. Li Shaocheng's troops are the main force of the Hundred Battles Army, although they suddenly went eastward, but in fact they have the intention of waiting for work, and it is not difficult to defeat the 10,000 Khitan reinforcements in Yingzhou.

Yelu Naer, who relied on the camp fortifications to stick to the inner camp, found that something was wrong with the Tang army outside the camp and was ready to go out of the camp to test, Li Shaocheng had already returned with a great victory. The main force of the Hundred Battles Army returning to the west swaggered past in front of the Khitan inner camp, showing off its might, which naturally inspired the morale of the Hundred Battles Army and hit the morale of the Khitan Army. When Yelu Naer on the gate saw this scene, he was so angry that he was about to split, and scolded Li Congjing for being cunning.

After that, Li Congjing suspended the attack on the Khitan inner camp, and the whole army retreated, camping twenty miles away from Yannan to recuperate. It didn't take long for Yelu to come late, and finally arrived in front of Yannan.

Yelu Yuyin did not enter the inner camp, and when he saw that Li Congjing was camping twenty miles away from the Khitan camp, he did not act rashly, so he camped in the south, twenty miles away from the Hundred Battles Army.

In the three camps, Yelu Naer is in the north and has nearly 20,000 troops, Yelu wants to hide in the south and has nearly 10,000 troops, and the hundred battle army is in the west and has nearly 20,000 troops. The Khitan army echoed from north to south, and could advance or retreat, and the Hundred Battles Army faced two Khitan military camps alone, which seemed to be weak.

However, in the face of the current situation, Li Congjing did not have half of the fear when discussing with the army, although the number of the Hundred Battles Army was not superior, but in the face of less than 30,000 Khitan troops, even if it was a frontal battle, he did not feel that the Hundred Battles Army would be defeated.

It is worth mentioning that the camp of the Hundred Battles Army was very large, large enough to accommodate 30,000 people.

For the whole day of the next day, neither the Hundred Battles Army, nor Yelu Xiangyin and Yelu Naer sent a large army to fight, and the two sides were at peace for a whole day. During this period, the Hundred Battles Army was closed, and Yelu was not in a hurry to fight, and the situation on the battlefield seemed to be at a stalemate.

During this day, Jerod and Jerunar met. Although he was extremely dissatisfied with the loss of Yelu Naer's outer camp, but at the moment of the great enemy, Yelu Xiangyin did not blame him too much, gathered all the generals and staff, and Yelu Xiangyin planned a strategy to deal with the hundred battle army. After the military discussion, Yelu Yuyin still let Yelu Naer return to the inner camp of Yannan.

In the early morning of the third day, the calm was broken, and Yelu wanted to hide with an absolutely superior force and launched an attack on the camp of the Hundred Battles Army. Yelu Yuyin and Yelu Naer attacked the camp of the hundred battles from the north and south sides.

The Hundred Battles Army did not sit still, and the main force of the army went out of the camp to respond. At that time, the majestic Khitan army of more than 20,000 assembled into two large arrays, and launched an attack on the large array of the Hundred Battles Army with infantry as the main force with cavalry as the main force.

On the watchtower, Li Congjing overlooked the battlefield and could roughly see the entire battle situation. In front of the watchtower, dozens of elevated highways, there are war drums, and the drummer in front of the drum holds his breath and stands solemnly. In front of the elevated road, there is a long line of hornmen. Further out, there is the Commander's Guards. Prior to this, it was the main formation of the regular army with the infantry in the center and the cavalry on both flanks.

The Khitan cavalry occupies the majority, on the flat battlefield, the cavalry has a natural advantage against the foot soldiers, Li Congjing and others on the watchtower saw that the Khitan army rushed in the first wave, the cavalry charged ahead, and the infantry army was still slow. When thousands of horses galloped and the earth shook and the mountains shook, the black crowd and the sweeping ironclad waves gave people an indescribable sense of oppression and fear.

Li Congjing pointed his finger at the Khitan cavalry rushing towards him, and there was a strong wind blowing his black cloak on the tall building, and he understated to Mo Li and the others beside him: "There are more than 15,000 Khitan elite cavalry, and now almost all of them are dispatched, sweeping towards me from the northeast and southeast directions. The infantry army that followed behind would break the formation head-on after its cavalry had seriously wounded our great formation. ”

Mo Li nodded, "Our army is mainly based on foot soldiers, and the cavalry is not as large as the Khitan army, only 5,000 people, and it is difficult to win in a head-on battle." And if its cavalry is allowed to wreak havoc on the formation, I am afraid that the formation will be disrupted by it. "This is the truth, the two armies are at war, and there are many factors that determine the outcome of the war, armament is one thing, and the mutual restraint of the arms is also one thing. In a general sense, cavalry is a natural nemesis of foot soldiers. In ancient and modern Chinese and foreign history, there have been countless examples of victories by relying on the superiority of the armed forces.

In fact, at present, for the Hundred Battles Army, retreating into the barracks to hold on can effectively avoid the disadvantage of the troops, so that the advantage of the Khitan cavalry no longer exists, and turn into a disadvantage, after all, attacking the camp, the cavalry is not as useful as the foot soldiers. However, when going deep into the enemy's territory and the enemy's number is superior, retreating to the camp is tantamount to trapping oneself, and once it is surrounded by the Khitan, it will be a big trouble.

He looked down at the battlefield, raised his arm, and ordered: "Order: The infantry army and the horse army strictly guard the formation, and wait for the Khitan cavalry to come to the front of the battle, and the horse army will come out and fight, and the strong crossbow and bow in the infantry army will be supplemented!" "This is a defensive tactic, based on the formation, not only to avoid being surrounded by the Khitan horse army, but also to become the backing of the horse army.

From time to time, the Khitan cavalry rushed to the front of the Hundred Battles Army from two directions. Attacking from different directions is a very wise tactic, which can not only disperse the opponent's military strength and combat power, but also make it easier to find flaws. Fortunately, the Hundred Battles Army took the camp as its back, and placed the most common glaive array, in front of the infantry formation, layers of carts, heavy guns, forming the most hideous defensive line.

As Yelu Xiangyin, who understood the tactics and formations of the Tang Army, he had no intention of rushing to the front of the infantry of the Hundred Battles Army from the front, and the cavalry he sent from two directions were on both sides of the Glaive Formation when they met the Hundred Battles Army formation.

"Ma Jun, out!" On the watchtower, Li Congjing issued a military order. When the cavalry attacks, it needs to increase the distance in order to exert its might, and if there is no cavalry running, it will become a foot pawn, or a bulky foot pawn, which is naturally not very useful.

The large array of the hundred battle armies with strong barriers, and the thousands of cavalry spread out on both wings gathered into two torrents, forming a strict military formation, facing the imposing Khitan army.

The two armies intersected, and fierce battles broke out.

The sound of galloping, shouting, colliding, fighting, deafening, entangled, is the four words Jin Ge Iron Horse. The surging crowds of people, the surging military formations, like the confluence of two great rivers, the collision of two chariots, the dense soldiers, you come and go, deep into each other's formations.

The sound of drums and footsteps echoed violently, on the battlefield, the flags of their respective generals galloped forward with their subordinates, and on the edge of the battlefield, the people standing on the tall buildings were standing tall, fluttering behind them, and the clouds were rolling overhead.

When the battle reached the end, the horse army of the hundred battles retreated slightly, and in the large array of the infantry army, a rain of arrows rose into the air, crossed a huge arc in mid-air, and fell into the Khitan cavalry group.

Foot and ride together, and fight without retreating.

The first wave of the Khitan army's offensive was repulsed after the Hundred Battles Army's infantry army exerted its strength in crossbows. But only a little back, the Khitan army pounced again.

If this is the case again and again, the day is getting higher and higher.

It had been a long time since the Khitan infantry army had followed, and Ben was waiting for its cavalry to give an overwhelming blow after the formation of the Hundred Battle Army. However, at this time, seeing that time was passing and the cavalry was stuck in the swamp of war, although the battle was fierce, it did not achieve the expected effect, and Yelu Yuyin finally ordered the infantry to cooperate with his cavalry to attack the army of the Hundred Battles from the front.

The Khitan army infantry paid a heavy price when cleaning up the fortifications in front of the Hundred Battles Army. Compared with the Khitan army, the Tang army's infantry army was already a lot more skillful, and the hundred battle army was elite. When the Khitan infantry took over the battle, the Hundred Battles Army first shot with bows and crossbows, and when the Khitan army stepped forward with a shield, the sharp arrows turned into rockets, and the scorching battlefield was scorching with more pieces of fire pools and smoke and dust. When the Khitan army finally touched the Tang army's chariot, the warriors of the hundred battle armies rushed out, in groups of three or five people, relying on the terrain of the chariot, shot from the gaps, and used heavy weapons such as giant axes and broadswords, so that the Khitan infantry could only retreat in embarrassment.

The two sides have come and gone, and the local battlefield has advanced and retreated many times, but the overall situation of the entire battlefield has been in a stalemate.

It wasn't until the twilight clouds merged that the two armies, who had not divided the winners and losers, finally stopped fighting and each withdrew their troops.
