Looking at the cavalry that came from the impact, Zhao Pu was extremely nervous.

Cavalry, in this era is invincible. Light cavalry is equivalent to light tanks, heavy cavalry is equivalent to heavy tanks, and whoever controls the cavalry will, to a certain extent, control the long-range combat capability, and whoever occupies the initiative on the battlefield. The Liao, Western Xia, and Jin kingdoms all started with powerful cavalry.

Not good at cavalry warfare was the biggest weakness of the Song army.

After Zhao Pu became the emperor, he also actively trained cavalry, but the technical content of cavalry was relatively high, either horses or cavalry, and cavalry needed to be trained for a long time. In a short period of time, the cavalry was low in combat effectiveness and was unable to fight.

At this time, with a loud concussion, the cavalry galloped forward, quickly crossed the trench, pushed to the low fence, and stormed.

Unexpectedly, at this moment, the Bazi Army did not form an infantry formation and resist layer by layer, but slowly retreated, as if it was a rout, and the Jin cavalry behind followed closely behind, rushing forward to kill. How can a horse run fast, the war horse is getting closer and closer to the soldiers behind, only about a zhang, only a sprint, you can kill in front of you, kill vertically and horizontally, and then chisel through the camp, completely crushing this Song army.

"It's not good, this Song army, defeated but not defeated, there is an ambush, be careful!" Looking at the battle situation, Wan Yanye chuckled in his heart, but it was too late at this time.

Coming out from both sides, one by one, shield bearers, this is a large shield.

The general shields are light shields, made of bamboo, covered with iron sheets, or cowhide, which can protect the vital points of the body, mainly hand-to-hand combat, mainly lightweight. At this moment, the shield is mainly large, more than a person tall, weighing fifty pounds, and it cannot be carried for combat at all, and there is a bracket behind the shield.

"Bang!" The heavy shields fell to the ground, leaning on the bracket, standing at a 60-degree inclination, and these shields appeared one after another, forming a large array of shields, like fish scales, layer by layer, overlapping and superimposing.

The diagonal shields became the biggest obstacle to the advance of the cavalry, and behind the shields were short knife hands, holding sharp swords in their hands. Some of the cavalry of the Jin Army entered the shield array, not only weakened in speed, but also were attacked by swords, guarding the left, not the right, the front, but not the back.

In a mournful roar, the leg of the war horse was cut off, and the cavalry of the Jin Army fell under the horse, and before they had time to resist, they were slashed with knives in all directions.

The cavalry of the Jin army was ruthless, wielding spears, hammers, maces, etc., but they had shields to resist, eliminating most of the offensive, even if they killed some Song troops, it was endless. At this moment, the zama knife showed a strong lethality, countless war horses were killed, and countless Jin soldiers were killed.

Zhao Pu looked at the battle situation and breathed a sigh of relief in his heart.

…………

In this era, cavalry is invincible, and infantry against cavalry is often less victorious than more defeated, and only cavalry can defeat cavalry.

The reason why the Han Dynasty defeated the Xiongnu was because there was a strong cavalry; The reason why the Tang Dynasty destroyed the Turks was because of a powerful cavalry. At this time, the cavalry was insufficient, and the cavalry could only be broken with infantry. And the infantry to break the cavalry is nothing more than four methods: one is to rely on the bow and crossbow to shoot the Jin army from a distance; the second is pikemen, forming a spear forest and sweeping the enemy; the third is to form a short knife hand and cut the horse's leg at close range; Fourth, rely on the vehicle formation to delay the cavalry impact.

The infantry phalanx of the Song army was mostly composed of four methods, with bows and crossbows striking from a distance, car formations slowing down the cavalry, and spears stabbing and killing. Short knife hands cut off the horse's legs. It's just that the plan is beautiful and seems to be the perfect infantry formation, but the reality is unrealistic. This is just the scholar's art of war.

First of all, this requires a large number of troops, three times, five times as many cavalry troops. In reality, however, in a defensive war, it is necessary to reserve a relatively large number of reserve troops, so that fires can be put out in a timely manner and loopholes can be filled in a timely manner. Too much investment will reduce the reserve force. Once a big loophole appears, it will be difficult to fill the loophole, and eventually the loophole will expand step by step, and finally the whole army will collapse.

Secondly, the cavalry had to charge into battle for the infantry formation to exert its might. But in fact, the Jin army is not stupid, when it sees that the infantry formation is densely defended, it will give up charging the formation, but it will be tempted again and again, and the physical strength of the infantry will be consumed again and again, and a dozen will take a day. The cavalry doesn't care, anyway, they fight on horseback, as long as they change their horses at any time, it is enough; But at the end of the day, the infantry did not eat or drink, and stood there, waiting for the battle, but they were a little unbearable. When the Song army is exhausted to the extreme, attack the weak point, and the seemingly powerful Song army will be crushed.

Again, the army must have a strong will to fight. But in fact, the Song army's will to fight was very weak, as long as the casualties were about 20 percent, the whole army would be defeated, and it would not be able to do the People's Liberation Army of later generations.

These three shortcomings doomed the seemingly perfect infantry formation, which was just paper paste and repeatedly defeated.

The only one who won was Yue Fei, and later generations even said: "It has the Golden Vulture Technique, and I have Marshal Yue; It has kidnapping horses, and I have hemp knives; It has maces, and I have heavenly spirit covers. ”

The Yuejia army, without the assistance of bows and crossbows, the assistance of spears, and the assistance of chariots, just relied on the saber, cut the cavalry up, cut the legs of the horses, and finally destroyed the Tiefutu and kidnapping horses. A thousand tricks will not be as familiar as one move, some fantasy, some legends, in fact, just relying on the saber, it is impossible to defeat. However, in some specific cases, the saber was the nemesis of the cavalry.

For example, at this moment, the cavalry lost its speed, lost its dense impact, lost its flexibility, and was divided and surrounded by Song soldiers with sabers. The heavy shields are distributed in a fish-scale manner, dividing the cavalry, dividing the cavalry into countless small pieces, and then covering with shields, and cutting off the horse's legs at close range; And the Song soldiers, who were hiding underground, suddenly attacked and cut off the horse's legs.

There are no superfluous tricks, and the tactics are not strange, when the lethality is significant.

Immediately, the cavalry of the Jin Army, which fell into the shield array, suffered a devastating blow, and within a moment, the entire army was annihilated.

The remaining cavalry of the Jin Army, seeing that the situation was not good, wanted to retreat, but it was too late. At this time, the cover of the ground was removed, and under the soil, the planks were lifted, and the soldiers of the Song army were like soil rats, exposed, waving sharp horse chopping knives, specifically cutting horse legs.

The cavalry wanted to fight back, but in order to be flexible, the weapons were short, and they couldn't cut the rats in the ground. However, the soldiers of the Song army were in great power, and the cavalry rolled off their horses one after another, and were finally hacked to death with random knives.

The soldiers of the Jin Army who lost their horses are still brave, but it is difficult to recover the defeat, and defeat is already a foregone conclusion.

Looking at the occupation in front of him, Zhao Pu was extremely happy in his heart, and finally let out a bad breath.

5,000 cavalry dared to attack the 30,000-character army. Since you have the courage to do it, you must be prepared to shed blood. Lao Tzu is not a small sufferer, Lao Tzu is the emperor, dare to despise Lao Tzu, Lao Tzu waved his hand to destroy you, the emperor was angry, and ambushed millions of corpses.

Looking at the battle situation in front of him, fear flashed in Wan Yanye's heart, before the battle, he had never thought of such a situation, at most it was difficult to attack, and finally retreated, he never expected that it would be such a situation. This Jin army is really cunning, leading him into a trap step by step, and in the end it is difficult to escape.

"Damn!" Looking at the cavalry of the Jin Army who was tragically surrounded and annihilated, Wanyan Ye's eyes were torn apart, his chest rose and fell, and a big defeat was in front of him, "Kill, rescue the brothers!" ”

It's just that at this time, a Song army appeared, blocking the waist and dividing the Jin army, cutting off the retreat of the cavalry who entered the big camp, and also cutting off the way for the Jin army to rescue outside. Based on the chariot, a two-way defensive position was constructed, among which there were the most elite pro-battalion soldiers.

"Kill!" A large number of Jin cavalry rushed in.

At this time, behind the chariot, the Song soldiers lifted the ground, and rows of water tanks buried in the soil appeared.

Igniting the explosives bag, Song Bing threw the explosives bag into the water tank, and immediately "boomed" with a loud sound, and the mouth of the water tank sprayed out, smashing into the opposite Jin cavalry, just like entering the cavalry formation, and suddenly people turned over on their backs, and the war horses were even more frightened, and they spun around.

Zhao Pu, who was in the distance, looked at this scene and sneered: "No conscience cannon, blow you up!" ”
