Although he looked very calm, Bai Quan's heart was actually a little nervous, after all, the huge trees carried by those strong men in the river on their shoulders were equivalent to a bridge, a bridge that could allow the cavalry army of the Xi Qi coalition army to cross the Sanggan River. Except for Fan Yang and Shuofang, who occasionally deal with Beiyi, the Tang army in Longyou and Hedong has only fought two foot battles with the Xiqi coalition army, and they may not know much about the strength of the Beiyi cavalry, but his recent observation can see that the combat effectiveness of these Beiyi cavalry is quite strong, and if they dismount, they may not be as good as the Tang army, but if they are on the horse, they can be a top two.

After all, they are all people who have spent all year round on horseback, and if they lose to the Han people in this regard, then they don't even want the grassland in a corner of peace, and they will be conquered by the Tang Dynasty like Anxi or Hanhai and become one of their capitals.

It was precisely because the cavalry of these Xi Qi coalition forces was very strong and extremely aggressive that he was a little worried, although the Tang army had already understood the ins and outs of the matter and set up many ambushes, they were all infantry. If the cavalry of the Xi Qi coalition army was not afraid of the sacrificial charge, even if the initial ambush could kill a lot, once their follow-up reinforcements poured into the Tang army camp, then they would be ruthlessly ravaged by the opposing cavalry.

The gap between infantry and cavalry cannot be bridged by quality, especially for cavalry like the Xi Qi coalition army, the gap is even more ridiculous, the most important thing is that they do not have a terrain advantage, and most of the 200,000 people are concentrated on the flat land centered on the large battalion. As long as one of them succeeds, it can tear apart the defense line of the Tang army, which will lead to the collapse of the ambush defense line, although the Xi Qi coalition army did not expect that the Tang army would set up an ambush, but this is very likely to happen.

Although in fact, as long as those strong men were shot now and the head of the giant tree sank in the Sanggan River, the cavalry could not cross the river to prevent this from happening, but whether it was Ye Chengcheng or Wang Zhonghe, from the beginning it was the idea of completely annihilating the Xiqi coalition army. They don't just want victory in the first battle, but permanent victory, so they must be completely annihilated and let them into an ambush.

However, this expectation is only because Bai Quan does not know the Tang Army, since he joined the Tang Army, he has been following Ye Qingcheng in action, and he has almost never seen how the official Tang Army fights, and those who have seen it are all small groups of personnel in the Tang Army, although the combat effectiveness is relatively high, but he has really never seen the biggest advantage of the Tang Army - that is, group combat.

In the correct history, the Tang army often used large-scale group operations to conquer the surrounding regions and nationalities, even if it was a strong and domineering, across the three continents of Asia, Africa and Latin America, the Arab Empire was also frightened by the Tang army under the city of Hengros, although it won a narrow victory, but it did not dare to step into the Tang Dynasty for the rest of his life, but only stopped at the Lite countries in the river.

However, his worries were also right, once any cavalry of the Xi Qi coalition army rushed into the Tang army camp, it would tear their defense line, and some generals in the Tang army pointed out this, so this ambush plan was opposed by them at the beginning, but due to Wang Zhonghe's face and the more support among others, plus the whole plan was actually proposed by Ye Chengcheng, and this plan was still adopted in the end.

At this moment, in the tent under his feet, there were more than a dozen generals standing on a map and discussing, while Wang Zhongsi was standing aside and calmly thinking about the overall strategy and layout. The map had already indicated the possible formations and the number of each of the Xiqi coalition forces, as well as the information about the bridge that had just been added to the Sanggan River, and the fellows were discussing what formations and methods to use to block them once the cavalry of the Xiqi coalition army had broken through their several lines, and some advocated arranging a large number of crossbowmen to set up the defensive line in front of the tent, because it was located on a small slope, and the terrain was better, so that they could see the movement on the flat ground up to the dock, and it was also suitable for archery. However, some people raised objections, on the other hand, if there are good archers among the other side's cavalry, once they rush into the camp, the goal must be to go straight to the tent, and the tent of the Tang army is also somewhat obvious, they can also shoot arrows to reach the tent, which is very dangerous.

So in the end, the opinions of most people were adopted, and a large number of heavy infantry were arranged to hold shields in front of the commander's tent for defense, but there were still hidden dangers, and they were now discussing how to eliminate these hidden dangers, so that the ambush was foolproof, and they had to make corresponding changes according to the dynamics of the Xiqi coalition army. Every half a cup of tea, a signal soldier will come to report the situation, and then a special soldier will make corresponding marks on the map for these generals to discuss the battle.

If it is changed to the camp of the Xi Qi coalition army, at this moment, the generals in the rear are gathering in Li Huaixiu's camp tent, but they are discussing how to divide the spoils after the victory of this battle, as well as the distribution when they go south to the Central Plains, and no one is discussing the military situation and military strategy, which is the biggest difference with the Tang army. Although Li Huaixiu felt very annoyed, but there was nothing he could do, after all, their nation was destined to be like this, and they were not awarded generals according to their ability, but according to their status in the clan, most of the generals present were the children of the nobles of the thirty-six departments, even if he was a big chief, he could not offend these guys, so he could only greet them with a smile and pretend to be interested to participate in their discussion.

After all, in his opinion, the Tang Army has not moved even now, and this is already doomed to the outcome of this battle, and all he has to do is to obediently wait for the report of victory to come.

In this tense atmosphere, the bridge-building troops in the Sanggan River finally broke through the river, climbed on the opposite bank, and came to the dock of the Tang Army, and then several strong men also quickly pulled out a few people, hurriedly climbed onto the dock, and helped lift one end of the giant wood onto the dock, and several people took out the hammer and rivets in an orderly manner, and drove the rivets into the stones on the dock ground through the two special holes at the top, and the first bridge was finally erected.

However, the sound of this move was a little too loud, and finally it attracted the attention of the Tang army, and it seemed that the Tang army began to run in the Tang army camp, which made these strong men on the dock and the previous group of people very afraid, and suddenly someone took out the horn and blew it all at once, anyway, it has been discovered, it is better to start breaking in now.
