Although it failed to conquer Huaixian, the result of this attack by the state army was quite satisfactory, and it was a brilliant victory. With the entry of the Tun Cavalry Battalion and the Xiao Cavalry Battalion into Hanoi, the field combat capability of the Bingzhou Army was strengthened, and Chen Tai led the remnants of the army to retreat to Huai County, where he was strictly guarded and had no idea of going to war again.

Chen Tai is now glad to have a place to stay, in fact, this time the battle situation is quite dangerous, a little bit of luck, Huai County may be lost, if Huai County is lost, Nuo Da Hanoi, I am afraid that even Chen Tai's place to stand is gone.

After this fiasco, Chen Tai no longer dared to fight easily, and sticking to Huaixian became his only goal. Although the losses of Sima's army in this battle were not small, there were still more than 30,000 troops that could be mobilized in Chen Tai's hands, and it must be more than enough to use these forces to defend a county town.

From the point of view of grain and grass, there is no big problem, Huai County's grain depot reserves are still very sufficient, I dare not say that there are many days, but there is no problem in holding on for two or three months, Chen Tai believes that Luoyang Sima Zhao will definitely not sit idly by, as long as Sima Zhao sends troops to help, his side does not need to hold on for so long.

As for the defense of the city, Chen Tai does not need to worry, under the same attack of the state army, Yewang and Wen County could not hold on and fell, but Huai County successfully defended, which undoubtedly proves that the defense capability of Huai County is better than that of other cities, and now there are more defenders of other cities to join, and the defense of Huai County is greatly enhanced, Chen Tai believes that even if all the men and horses of the state army come to attack, they may not be able to take Huai County.

In fact, Cao Liang had no intention of taking Huai County at all, and after the whole division of the state army entered Hanoi. It stands to reason that it should be a good time for the troops of the Bingzhou army to press the border and take Huai County directly, but Cao Liang never sent troops to Huai County again.

After Chen Tai fled back to Huai County, Huai County's defense capability was greatly strengthened, and if he went to attack Huai County again at this time, he would inevitably encounter such a nail that was neither soft nor hard.

Even if the Bingzhou army now has a catapult, but the siege battle, still have to pay a considerable price of casualties, originally Cao Liang hoped to be able to sneak attack and minimize the loss, but unfortunately, Liu Jing's right guard battalion was not able to take Huai County, now all Chen Tai's soldiers and horses are concentrated in Huai County, the difficulty of conquering Huai County has greatly increased, Cao Liang may not be willing to concentrate all his forces to attack Huai County.

Of course, this is also considered from a strategic point of view, if conquering Huai County is a strategic goal that must be achieved, then Cao Liang will not hesitate to pay a big price.

However, now Cao Liang does not have much idea about attacking Huaixian, this attack on Hanoi, Cao Liang is not ready to stick to the benefits he has gained, after all, compared with Hanoi and Shangdang, the terrain is too flat, there is almost no danger to follow, if the Sima army counterattacks in the future, these cities that have just arrived may not be able to hold.

Since it can't be defended, it will be abandoned sooner or later, so it becomes unnecessary to devote all your forces to attack Huaixian.

The biggest purpose of this invasion of Hanoi was not to conquer the city, but to threaten Luoyang, deter Sima Yi, and provide some friendly assistance to Wang Ling in Huainan through such a large-scale military operation.

As for how much Wang Ling can be helped, I'm afraid only God knows.

For this great victory, the entire Bingzhou army was jubilant, especially in the battle of Wulongkou, Ma Long's vanguard battalion performed amazingly enough, with a team of 3,000 people, resisted Chen Tai's tens of thousands of horses, and inflicted heavy losses on the enemy, such a record naturally became the focus of heated discussions among the generals of the Bingzhou army, and even became a new trend in infantry combat.

In the plains, infantry against cavalry, usually a headache, whether spears or chariots, people are always trying various defensive formations, hoping that the infantry will no longer be crushed by cavalry.

At the beginning, people usually used the current vehicles, such as baggage vehicles, to build defensive positions to block the attack of cavalry, and later developed some special chariots to deal with cavalry.

However, Ma Long's flat box car formation, the chariot formation of the combat method to a new height, tall and sturdy flat box car, all the same color of crossbowmen, Ma Long changed, is a new theory of infantry combat, this kind of extreme defense and offense, so that the flat box car formation in the fight against cavalry, has a unique advantage.

So is the flat box car formation really invincible? Can it become a combat template for infantry from now on?

This also seems to have become the focus of heated discussions, if you can't find a way to crack the flat box truck, then it is likely that the flat box truck will become the standard mode of infantry combat in the future.

However, what is slightly lacking is the mobility of the flat box car formation, the flat box car is too bulky and slow, and the crossbow soldiers who are overly dependent on the flat box car can only stay in the car formation, unable to jump out of the car formation to fight independently.

The great victory in the Battle of Wulongkou was entirely based on Chen Tai's eagerness to eat the pioneer battalion's continuous rapid attack, and if Chen Tai had adopted the method of slowing down the attack or besieging but not attacking, the pioneer battalion might not have been able to win so much.

The advantages and disadvantages of the flat box car formation are equally clear-cut, so much so that both those who support it and those who oppose it are very clear-cut.

Proponents believe that the flat box car is very practical and should be popularized in the army and widely equipped, so that the infantry will not be so difficult to deal with the cavalry.

However, opponents believe that the maneuverability of the flat box car array is too poor and is only suitable for small-scale use, and it is not recommended to promote it.

In the tent of the Chinese army, everyone was fighting for each other, each holding their own opinions, and refusing to give in to each other, but Ma Long, the central figure of public opinion, sat on the side, laughing and not saying a word.

Seeing that this controversy was intensifying, and no one could convince anyone, Cao Liang coughed lightly, interrupted everyone's discussion, and said: "It seems that everyone is very interested in the flat box car, yes, this battle of Wulongkou, the pioneer battalion fought really well, quite beautiful, and it also proves that the flat box car is indeed a sharp weapon in dealing with cavalry, such a good combat method and weapon innovation is naturally the most needed in the army, and such experience also needs to be learned by all battalions and departments." But everything has two sides, no weapon is invincible, Xiaoxing, you are the inventor of the flat box car, I'm afraid you know the flat box car better than anyone else, the advantages of the flat box car have been seen by everyone, so there is no need to repeat it, you talk about the way to crack the flat box car. ”
