Yannan is located in the north of Jizhou, there is no mountain barrier between the two, and there is no Great Wall fortress, but a smooth road, the reason why the Khitan rangers were able to enter and raid the military fort in the north of Jizhou before is because of this. From the north of Jizhou to the south of Yannan, the distance is not far, otherwise Yelu Xiangyin would not be able to follow Yelu Gemeng so closely. When Ma Huaiyuan led the Jizhou army to ambush Yelu Gemeng and fell into a bitter battle with Yelu Xuanyin, Li Congjing led the Hundred Battles Army to the north.

Li Congjing's goal was very simple, that is, Yannan, one of the two base camps of the Khitan troops on the southern front.

In order to prevent Li Congjing from supporting the Bohai State, Yelu Abaoji set up two garrisons in the south of the grassland, Yannan and Yingzhou, which echoed each other to block the connection between Lulong and the Bohai State. This is also why Li Congjing said before that the Khitan army in Yannan and Yingzhou was a thorn in the flesh.

Without pulling out the nail of Yannan and Yingzhou, Li Congjing would not be able to support the Bohai State and pull the Khitan into the swamp of the long war that he had been planning for a long time.

After Yelu Abaoji stationed troops in Yannan and Yingzhou, he did not sit back and relax because he felt that he was choking the traffic arteries, and he had nothing to do in the sun all day long, he ordered Yelu to hide and let him make trouble for Lu Long, so that Li Congjing was tired of coping, so as to drag Li Congjing before he conquered the Bohai Kingdom, so that Li Congjing would not have the energy to move other crooked eyes.

The first step in Yelu Yuyin's plan was to send elite rangers to attack the military fort in the north of Jizhou. The subtlety of this move lies in the fact that after the Khitan rangers attacked the northern military fort of Jizhou, the army did not take advantage of the situation. The purpose of doing this is to make it impossible for Li Congjing to figure out the strategic purpose of Yelu Wanting to hide, in order to achieve the goal of a blind obstacle. At the same time, Yelu wanted to sharpen his sword and prepare his army to deal with Li Congjing's moves at any time.

However, what Yelu Xiangyin didn't expect was that Li Congjing's action to recapture the northern military fort in Jizhou came too suddenly, so fast that Yelu Xiangyin was not able to enjoy the pleasure that made Li Congjing at a loss, and he himself fell into a dilemma. The reason why Li Congjing was able to recapture the northern military fort of Jizhou in a very short period of time was, on the one hand, because of his decisive decision-making, but more importantly, on the other hand, it was because Ma Huaiyuan led the hundred horsemen to the north in advance and saw the situation of the military fort in Daoshuigou with his own eyes, so the speed at which the news was transmitted to Li Congjing was very fast.

In this way, Yelu wanted to hide that he couldn't figure out Li Congjing's strategic intentions, and when the military intelligence department hunted down all his eyeliner spies, he didn't even know what kind of black hand was behind the thousands of horsemen of the Jizhou army who suddenly went north.

The two sides fought each other, and between this back and forth, the situation on the battlefield changed several times, and it once became a confusing situation, which made people scratch their heads.

In order to hold the initiative in his hands again, Yelu Yuyin sent Yelu Gemeng to lead 3,000 horsemen to open the way. On the one hand, he wants to probe Li Congjing's backhand; On the other hand, he also wanted to see if he could take advantage of the situation to take Jizhou, create more trouble for Li Congjing, and gain more room for maneuver and military initiative.

The confrontation on the surface, whether it is the battle for the military fort in the north of Jizhou, or Ma Huaiyuan's ambush of Yelu Gemeng, and Yelu Xiangyin's defeat of the Jizhou army, is not something difficult to see, and the confrontation in the secret, in addition to the battle of wits and courage between Li Congjing and Yelu Gemeng, there is also a crucial point, that is, the confrontation between the scouts and spies of the two sides.

In the confrontation between the scouts and the spies, Li Congjing, who had the sharp blade of the Military Intelligence Department, took a big advantage.

First, through the military intelligence department to hunt and kill Khitan scouts and spies, Li Congjing made Yelu want to hide the vision in Jizhou; Second, Li Congjing still maintains a certain degree of control over the Yannan Army, at least, he knows where the Yannan Barracks is.

After the battle has progressed to this point, the contradictions have been fully intensified, and it is time to usher in a high tide. The next thing to be revealed is the specific time when this high-tide point will arrive, and who will set it off.

Yelu wanted to hide that Yelu Gemeng pursued Ma Huaiyuan, with a deeper purpose, and Ma Huaiyuan ambushed Yelu Gemeng, which also had a deeper intention.

This intention is that if Ma Huaiyuan can successfully ambush Yelu Gemeng, and the Khitan has no reinforcements, then the Hundred Battles Army will not act, Ma Huaiyuan will rely on the power of the Jizhou Army to eat Yelu Gemeng alone, after the end of the war, the rhythm of the confrontation between the two sides will be temporarily slowed down, and the intensified contradictions will also cool down slightly; If when Ma Huaiyuan ambushed Yelu Gemeng, the Khitan reinforcements came, but they did not come much, the Hundred Battles Army would follow, and together with Ma Huaiyuan, they would eat Yelu Gemeng and the Khitan reinforcements, which was also an extraordinary result; The last situation is the situation that Ma Huaiyuan is facing at the moment, that is, there are a lot of Khitan reinforcements, and when this situation appears, Li Congjing will raise the already intensified contradictions to a higher level, and push the war to a high tide in one step.

During the march of the Hundred Battle Army, Mo Li said loudly: "According to the prior deployment, if there are too many Khitan reinforcements and more than 10,000 troops with Yelu Gemeng, Ma Huaiyuan will resist for a while, and then fight and retreat." In a big battle of 15,000 men, as long as it is not a rout on the Great Plains, the inferior side still has the strength to struggle by relying on the terrain. As long as Ma Huaiyuan holds back the Khitan army for a day or two, our operation will be successful. ”

"Ma Huaiyuan is a veteran general on the battlefield, he is talented, he leads five thousand Jizhou foot cavalry, relying on the hilly terrain, it is not difficult to drag the Khitan army." Li Congjing said, "Even if those Khitan reinforcements found out that something was wrong and wanted to return to Yannan, it was too late." ”

Mo Li continued: "Yelu wants to hide in Yannan with 30,000 troops, more than Yingzhou, he sent more than 10,000 elite horsemen to the south this time to fight with Ma Huaiyuan's Jizhou army, and there are less than 20,000 troops left in his base camp, but I am afraid that there will not be many cavalry." I have 20,000 troops in 100 battles against 20,000 Khitan troops, and the odds are still some. ”

From the very beginning, Li Congjing made up his mind to eat the 50,000 Khitan troops in the north of Lulong, and this time he finally waited for the opportunity to divide the troops of the Yannan Khitan Army, which can be regarded as the favor of God, how could Li Congjing not patronize the base camp of the Yannan Khitan Army and serve them in a pot?

Li Congjing said: "It can't be that there are only some chances of winning, it has to be eight to nine out of ten." Otherwise, our trip will be in vain. The sacrifice made by Ma Huaiyuan and the Jizhou army became meaningless. ”

"It's not that hard." Mo Li shook the folding fan.

In order to attack the Bohai State and the Tang Dynasty, and because the Khitan is now flourishing the city and building the country with a city-state, although the cavalry is still the unshakable main force in the Khitan army, the number of infantry troops is also increasing. As Li Congjing expected, the Khitan army stationed in Yannan was the main force, accounting for as many as 10,000 people. This is not to say that these Khitan infantry soldiers will not be able to ride and shoot and step on war horses, they are still well-known knights, but in the establishment of the Khitan army, they are used as infantry troops. The armament is the configuration of the infantry army, and the method of battle is the infantry tactics, so even if they can all ride and shoot, it is just an infantry army that can ride and shoot.

Because when Yelu Xiangyin led ten thousand cavalry south to support Yelu Gemeng, for some reason, he did not play his own banner, so Li Congjing and others did not know that the Khitan army faced by the Jizhou army led by Ma Huaiyuan was Yelu Xiangyin himself. At this time, who was sitting in the Khitan Yannan camp, Yelu Naer, the deputy envoy of Yelu Wanten. Yelu wanted to hide before going south, let Yelu Naer sit in Yannan, and gave him a very clear military order, there was only one thing, that is, to be ready to fight at any time and march to the hinterland of Jizhou.

Today is a good weather, the grassland is endless, the field of vision is very vast, as long as you climb a little, you can see everything within a radius of more than ten miles. Yelunar, who had been on the corner tower of the barracks for a long time, looked south and looked away for a long time, but did not find anything unusual.

He had received a military report that Yelu Gemeng was ambushed by the Tang army when he was in Jizhou and was in a critical situation. After a fierce battle, thousands of Tang troops were defeated and fled. It's just that the combat strength of these Tang troops is quite sophisticated, especially some of the soldiers after the break, when the main force of the Tang army retreated, relying on the terrain that was not conducive to the development of the Khitan, they dragged Yelu to hide for an hour or two.

But that's about it. Two hours later, Yelu wanted to break through the Tang army's defense line, defeated the remnants of the Tang army's broken army in one fell swoop, and beheaded his generals, and then continued to pursue the Tang army to the south.

However, this group of Tang troops is a little cunning, although they are defeated and retreated, and the losses are not small, but it is rare that the fighting spirit has not collapsed, and with the hilly terrain, it has caused a lot of trouble to Yelu Xiangyin's pursuing army again and again.

But for Yelu Xiangyin, these troubles are just a trick to dismantle, they are outnumbered, and they use a single force to break through the Tang army that is trying to counterattack again and again, and the results have expanded again and again.

The battle reports in front of him will be delivered to Yelunar once every three hours, and looking at these exciting battle reports, Yelunar is happy in his heart. In the latest military report he received, Yelu Yuyin told Yelu Naer that he could almost see Jizhou City! Yelu wanted to hide that Yelu Nar was ready, ready to go south at any time.

Although he did not go to the battlefield, just reading the military newspapers, it was as if he had experienced a whole day of great war. At dusk, he ordered the whole army to rest early, and prepared for the military order to go south that was very likely to be received tomorrow.

After falling asleep, Yerunaer had a dream in which he dreamed that he was standing at the head of the city of Jizhou. And at the feet, there are corpses all over the Tang Army.
