Sima Yi is experienced, and the timing he chose when releasing the wolf smoke was completely right.

At this moment, the Wei army had successfully crossed the river with more than 20,000 troops, and after crossing the Huai River, they took the initiative to arrange troops on the south bank of the Huai River and establish a defensive formation.

At this time, Zhuge Jin, who was the commander of the Right Route Army, was more worried, he knew very well what kind of person Sima Yi was, even if he was a genius like his younger brother Zhuge Liang, he would be helpless when he met Sima Yi, and his son Zhuge Ke was more trusted, and wanted to implement a plan to attack half-crossing, and hit the Wei army Yu An Fengdu hard.

As the name suggests, the half-crossing attack is to wait for the enemy army to cross the river halfway, and then attack, taking advantage of the opportunity of the enemy's unstable foothold to inflict heavy damage on the enemy who has already crossed the river.

Zhuge Jin observed that after the Wei army crossed the Huai River, he did not cheer and celebrate, let alone get carried away, but very pragmatically built a simple but solid defensive formation on the south bank of the Huai River to deal with the danger that might come.

Can't wait any longer!

Zhuge Jin's expression was grim, and he briefly discussed it with the deputy general Bu Qi, thinking that if according to the original plan, when the Wu army waited until the Wei army really crossed half of the men, I am afraid that the Wei army would have already formed an iron bucket-like formation, and when it really arrived, the Wu army would have to gnaw on this hard bone, and I am afraid that it may not be able to take it.

Therefore, Zhuge Jin planned to launch an attack in advance, no matter how many men and horses the Wei army crossed the river now, when the Wei army was not firmly established, he would make a decisive move to annihilate the army that had crossed the river.

Bu Qi quickly agreed to Zhuge Jin's plan, and they didn't even have time to say hello to Quan Cong of the Eastern Route Army opposite, so they didn't have time! Zhuge Jin decisively ordered the Wu army to move, launched an all-out attack, and slashed the Wei army's army on the south bank.

All this had long been expected by Sima Yi, and the so-called half-crossing attack was just a tactical name, and in actual combat, I am afraid that no general could wait until the enemy's army was actually halfway through before launching an attack.

He sneered slightly, and ordered his own soldiers around him to light the dry pyre that had been prepared long ago, and a thick and black wolf smoke rose into the sky and soared into the sky.

In the ancient times when communication was underdeveloped, wolf smoke has always been an effective means of communication, the beacon tower on the Great Wall, it is always ready to ignite the fire, once the enemy invades, it will immediately ignite into the wolf smoke to warn, thousands of beacon towers are passed one by one, and its scene is also magnificent.

As the name suggests, wolf smoke is ignited with wolf dung, but in actual operation, the effect of wolf dung is not too obvious, the real wolf smoke is ignited by mixing dry firewood, wet wood and grease materials, such wolf smoke is black and thick, can go straight to the sky, the effect is the most obvious.

The early attack of the Wu army put a lot of pressure on Sima Yi, and now the Wei army that crossed the Huai River was less than 20,000, and it was difficult to withstand the large counterattack of the Wu army.

However, Sima Yi kept his back hand, although he didn't know that Xiahou Xuan's army had arrived there now, but according to the agreement, as long as the wolf smoke was together, Xiahou Xuan would lead the army to rush to reinforcements desperately, and the inside and outside should be combined to attack the front and back, killing the Wu army by surprise.

Sure enough, Xiahou Xuan, who had been waiting in Changfeng Forest for a long time, was already very anxious, if Sima Yi didn't send a signal from his side, he felt that he really couldn't hold on, after seeing the wolf smoke, Xiahou Xuan suddenly became a lot more relaxed, and immediately drew his sword and ordered the whole army to attack and attack the Wu army.

After receiving the military order, Wen Qin immediately ordered that three thousand Xiao cavalry rushed out like a torrent of iron horses, and rushed towards the Wu army's camp with an unstoppable momentum.

The biggest reliance of the formed cavalry is speed, thousands of horses, roaring, powerful impact can completely destroy everything, unstoppable.

The Wu army set up camp here, and all their attention was on the Anfeng Ferry, so that the defense behind the camp was extremely weak, there was not even a decent fence, and a few sparse and slender branches served as fortifications.

This kind of fortification, in front of the cavalry battalion, is simply useless, and the cavalry easily broke through this layer of fortifications and entered the position of the Wu army.

Not only the weakness of the fortifications, but even the state of the soldiers in the camp was muddy, and all the attention of the Wu army was on the front, especially after the battle, all the Wu soldiers and Wu generals were all looking at the front, even if they did not participate in the battle, the focus was naturally on the Anfeng Ferry.

Three thousand horsemen rode like entering a no-man's land, slashing and killing all the way, smashing the camp of the Wu army, destroying the barracks, and the Wu soldiers who were guarding the camp only hated their father and mother for giving birth to two legs, and it was almost impossible to escape.

The speed of people is far inferior to that of war horses, and even if a person runs fast, he can only run in front at most, facing the wolf-like iron horse behind him, which really makes people feel desperate.

When 3,000 horsemen swept through the entire Wu army camp, the infantry of the Zhengnan Army also rushed up, and in the face of a wolf-like battlefield, the Zhengnan Army looked like scavengers rather than infantry participating in the attack.

The Wei army killed from behind without warning, which made Zhuge Jin's heart suddenly cold, what he was most afraid of when fighting, that is, being attacked by the enemy on his back.

Now that the Wu army had just launched an attack on the beachhead of the Wei army, and the two sides had just entered the moment of hand-to-hand combat, an army suddenly came out from behind the Wu army, which caught Zhuge Jin off guard.

It seems that the Wei army has been prepared for a long time, and has already taken countermeasures against the ambush plan of the Wu army, when did such a strong army actually go around the back of the Wu army, Zhuge Jin was completely unaware and derelict in his duties! What a serious dereliction of duty!

The movements of the Xiao cavalry battalion were extremely fast, but it was only a moment, it had already broken through the camp of the Wu army, killing countless enemies, and then the three thousand Xiao cavalry did not wait for the infantry to follow, and they drove straight into the army and began to attack the attacking army of the Wu army.

The direction of the Wu army's attack is Anfeng Ferry, and the direction of attack of the Xiaocai battalion is also Anfeng Ferry, the two sides are going in the same direction, and the Xiaocai battalion can completely chase the Wu army's ass to fight.

The army pays attention to the formation in battle, what kind of soldiers are arranged, what kind of formation is arranged, and the sudden appearance of the cavalry battalion seems to have disrupted the deployment of the Wu army.

The chaotic formation is what the cavalry likes the most, they can have the enemy army galloping back and forth freely, rampage, as if they have entered a no-man's land, without resistance.
