"Withdraw!" Liu Guojie said half helplessly and half panicked. Today, he wanted to break through the Song army's defense line as soon as possible, but when he found a 'flaw' in his defense, he launched an attack at any cost, but it was always difficult to open the gap, but it made people feel that they could break through as long as they worked hard, and as a result, nearly 2,000 casualties were still unsuccessful.

The huge losses made the Yidu army demoralized, and it was already on the verge of collapse, but what made Liu Guojie collapse was his miscalculation, when the Song army suddenly counterattacked, he immediately understood that there were not only more than 10,000 enemy troops in this valley, and people were not just coming to protect the tomb, but there was a bigger conspiracy in it, and their Yidu army and Shangdu army were just their appetizers.

However, remorse is remorse, Liu Guojie knows that if he retreats now, he will be wiped out if he does not do well under the pursuit of the Song army that has already begun. So he gathered all his forces to line up to meet the enemy and wait for reinforcements, and at the same time let the guy who had deceived him block first, so as to gain time in the formation. He felt that after all, this was still Dayuan's territory, and it would not take long to mobilize reinforcements, as long as he insisted until the reinforcements arrived, there would still be a chance to turn the tables, and he would be considered to have an explanation at that time.

But when Liu Guojie saw the Song army rolling along the mile-long battle line in unison, annihilating the cavalry on the march, his heart was half cold, which showed that he was not only well defended, but also had a strategy against the enemy in the field. And when attacking the formation, seeing that the Song army was still able to advance in a neat formation regardless of casualties despite the rain of arrows, his heart was also cold.

As a veteran of the battlefield with rich combat experience, Liu Guojie has faced the enemy countless times, and he has seen a lot of troops who can advance in battle, but he can face the enemy's muzzle, enough to keep the formation not chaotic, meet the enemy's volley, move forward quickly, and counterattack without firing a shot, and he has never seen it until he shoots at forty paces. He knew that this required not only strict discipline, but also great courage from all over the army.

Liu Guojie thought that his Yidu army could not do it, and looking at the entire Yuan army, perhaps only the Great Khan's cowardly Xue army could compare with it. The facts also proved his judgment, and a volley of the Song army killed more than 20 officers below the centurion and more than 500 ordinary soldiers, and the wounded were not counted, and they rushed away from their positions in an instant, and at the same time crushed their confidence.

In the face of the soldiers who abandoned the formation and fled, Liu Guojie cut more than a dozen people in a row before they barely collapsed under the repeated salvos and step-by-step pressure of the Song army, but the Shangdu army defending both flanks began to retreat first, which became the last straw that crushed them. Everyone knows that without the protection of the two wings, they will face the situation of being divided and defended by the Song army, Liu Guojie's mood at the moment is really indescribable, and with a long sigh he ordered to retreat and reorganize the defense line at the mouth of the valley.

However, Liu Guojie no longer had the luxury of hoping to block the Song army in the valley, and only wanted to avoid being chased and killed by the enemy, after all, now the four-legged ones can no longer be fingered, and he only hopes to reduce some losses. But he forgot that his idea was based on his own heavy losses and demoralization, and he gave the order to retreat and let the sheep go, and no one wanted to fight these perverted Song troops.

At this time, the Song army was no longer advancing slowly like just now, but changed the horizontal team into a column, and pursued quickly in the rear, they first returned to the crowd that quickly advanced and retreated with stragglers, and then intercepted them in a roundabout way, cutting them out of the brigade, and then the brigade immediately followed, if they resisted, someone would shoot first, and then step forward regardless of whether they were dead or alive, and then stabbed with a spear, and those who were not dead were also dead.

If there are many people surrounded, the Song army will fight in groups of three or five, and there are few who fight alone. When encountering a strong opponent, one person will come forward to fight him, and the other two will wait for the opportunity to sneak attack, and if they show a flaw, they will be stabbed under the gun. If they fall behind, if there are still bullets in the gun, they will not hesitate to kill the enemy who poses the greatest threat to them first, and then they will cover each other back to back and attack and defend together. However, this technique is rarely used, and it seems that most people will abandon their weapons and surrender as soon as they are divided.

"Wanhu, the cavalry of the Song army was found outside the valley!" Liu Guojie was surrounded by the rout and rushed out of the valley, and at this time, a pro-soldier sweating profusely rushed over and reported.

"What about the Shangdu Army? Didn't they intercept? Liu Guojie asked anxiously.

"The Shangdu army has been intercepted by the enemy cavalry, and the two sides are fighting fiercely, do our troops help each other?" The pro-soldier reported back.

"Help a fart, go quickly, go back to Shaoxing!" Liu Guojie, who was already dead-faced, was in high spirits when he heard this, and scolded his own soldiers. He knew that there was still a chance of life when he was pursued by the infantry army, but if he was entangled by the cavalry, it would be a dead end......

After receiving the signal that he could launch an attack, Fang Sheng immediately led his troops to maneuver out of the valley from the passage opened up in the tidal flats on the east side of the valley, but he did not rashly launch an attack. His Majesty's orders were clear: to attack the enemy cavalry when they withdrew from the valley, not to fight them, and not to hold on when the enemy had been defeated, and not to distance themselves. If the enemy breaks through, do not pursue.

At first, Fang Sheng still felt a little inexplicable, thinking that His Majesty had doubts about the combat effectiveness of their cavalry brigade, but he still strictly carried out the order. After the enemy cavalry took the lead in withdrawing from the valley under the attack of the infantry troops, a regiment was immediately sent to attack. They form a miniaturized diamond formation with the capital as a unit, with the capital leading one team as the spearhead, and the other teams are divided into other corners of the diamond formation, one as a guard and two as a flanker, so as to facilitate the spearhead when changing the direction of impact.

Compared with the large group operations commonly used in horizontal or column formations, the movement of this small tactical unit is more rapid and convenient, and it can quickly change the direction of the entire squadron, so the diamond formation is also easier to concentrate on breaking through a point on the battle line and expanding the gap, and at the same time it is more conducive to efficient distribution of troops, of course, this also requires the perverted formation change.

The cavalry of the Yuan army also reacted quickly, and when they found the cavalry of the Song army, they immediately divided a team of 1,000 people to meet them, and the two sides quickly collided together. In fact, cavalry battles will never occur for a long time, and often the two sides open their formations, allow each other to pass, and fight with the wrong horses. The dead and wounded were killed, and the living quickly assembled and re-hedged, until the morale of one side collapsed and retreated. And the key is to see who can complete the second assembly as quickly as possible and launch another attack.

As soon as the two armies clashed, Fang Sheng found that the perverted cavalry drill code formulated by His Majesty was really useful, it was simply to use cavalry as infantry training, which not only required tacit understanding between men and horses, but also required to be able to complete formation conversion in complex situations, and a qualified officer had to be proficient in the passwords of various tactical movements, and sometimes thirty individual passwords were required for one operation, which was simply a kind of torture. In addition, it is necessary to conduct frequent joint training at the city and regimental levels to cultivate organizational coordination and organizational control capabilities.

At this time, the performance of the Song army was to outperform the Yuan army, they formed a formation to hedge past the enemy group, and then the scattered teams immediately found their own military flags, quickly formed a team, and completed the reorganization and re-entered the battle in a very short time. The next situation does not need to be thought of, one side is morale, and the other side is eager to flee for his life; And the side with high morale at the moment has completed the assembly first, and the other side is still in the whole team, so the result is that the Yuan army released the ducks under another impact.

The enemy's vanguard cavalry dispersed, Fang Sheng led the second and third regiments to join the battle group at the right time, surrounded the Shangdu army, and the two armies rushed back and forth in the fields outside the valley, broke up, reassembled, charged, dispersed, and reassembled. After several times, the Shangdu Army, the old powerhouse in the Yuan Army, was beaten by the infantry and cavalry of the Song Army respectively, and was no longer able to support it.

Fang Sheng did not order the pursuit, and after gathering his troops, he turned into the battle of chasing and destroying the Yidu army. The addition of cavalry made the Yidu army even worse, and it could no longer stop its decent resistance, and it fled all over the mountains and fields, and it was already crushed. Liu Guojie was shot and killed by indiscriminate gunfire under the battle, and the handsome flag fell, seeing that there was no hope of breaking through and there was nowhere to escape, the remnants of the soldiers abandoned their weapons and surrendered......

When the battle reached Shen, the war was basically over, and Zhao Yu finally obtained 'approval' to go to the frontier battlefield under the company of Ni Liang and several escort officers and the protection of a team of guards, and the battlefield was basically unchanged at this time. He inspected the battlefield without the intention of showing off his merits, but wanted to obtain actual combat data through close surveys in order to sum up experience.

Zhao Yu and his entourage first came to the forefront of the fortress, which had endured the most violent bombardment of the stone thrower, and stones of different sizes could be seen everywhere, the smaller stone bullets had traces of human processing, and the large stones were all in a natural state, obviously taken from local materials. He picked up two stones and looked at them, each with a semi-cylindrical groove in the middle, which was put together in a complete spherical shape, which was obviously the stone hollow bullet equipped by the Yuan army.

"The gunpowder power of the Yuan army is still a little worse, and the stone bullet is only split into two pieces!" Zhao Yu twisted his face to everyone.

"The Tartar flowering shell is really less powerful than the equipment of our army, at most it can only be broken into four or five pieces, and some of them do not even explode, but at the beginning, the soldiers were still startled!" Li Zhen, the commander of the Second Brigade, also picked up a few broken stone bullets and showed them to the little emperor.

"Oh, show me one for fried." Zhao Yu listened to the words.

"Your Majesty, this ...... Too dangerous, right? Li Zhen was stunned.

"What's so scary about a dud, go!" Zhao Yu said with a scowl face. Seeing that he was angry, everyone hurriedly went to find one, but they still soaked it in water before daring to hand it to him.

"This ......" Zhao Yu just wanted to study the structure of the stone hollow bullet in order to understand the development degree of the enemy's equipment firearms, but after such a bubble in water, it was no longer visible. He smiled helplessly, and asked for a dagger to dig open the mud seal that closed the hole, poured out the gunpowder inside, broke the mud seal again, took out the fuse in it, twisted it and looked at it carefully.

"Your Majesty, how's it going?" Ni Liang asked.

"The fuse they used was just a paper twist, which may have been blown out by the strong wind, or it could have been so wet that it burned incompletely, and it was extinguished before it hit the ground. And the amount of charge in it is not small, which shows that the gunpowder formula they used has not been improved! Zhao Yu analyzed.

"It's best to let them get the secrets in their hands and we're out of luck!" Li Zhen said with a smile.

"What's the matter with the guns over there?" Zhao Yu walked up to the protrusion of the prismatic defense line, found a few muskets on the side, and asked busily.

"Report, those guns can't be fired, so they can only be put aside and wait for repairs." An officer on duty above immediately reported.

"Oh, the failure rate is so high?" Zhao Yu picked up a gun and frowned, this protrusion can accommodate a team of soldiers to defend, but there are seven or eight failures, which is really beyond the norm, after looking at it carefully, he asked again, "These guns are not all parts of the problem, right?" ”

"What Your Majesty said is that some of the soldiers, because they were nervous, did not know whether they had fired their guns or not, and reloaded again, blocking the chambers of their guns; There are also cases where after loading, the gun is fired without taking out the strip, and as a result, there is no way to reload the bullet; Then the gunpowder was scattered with a shaking hand, and the amount of charge was too small to shoot the lead bullet, so that it could not be reloaded! The officer on duty blushed and said.

"I'm afraid there are a lot of empty guns!" Zhao Hao picked up two projectiles on the ground and smiled.

"Exactly, because of the panic, the projectile fell off when charging but didn't know it, and there was also a delay in the projectile that was not wrapped, and the muzzle drooped and slipped out!" The little officer said embarrassedly.

"It's forgivable to be a little nervous for the first time, but the same problem must not occur next time, otherwise it will be your own life!" Zhao Hao smiled.

"Yes, there will never be a similar mistake again!" Hearing that His Majesty had no intention of punishing, the officer on duty hurriedly saluted and replied.

Then Zhao Yu asked some details about the situation of the fortress after being hit hard by the catapult, how they dealt with it on the spot, where the enemy chose to break through, how many people they suffered and killed, how much ammunition they consumed, and so on. Then along the city wall went up to the White Tiger Ridge fortifications, and they stopped at the end of the battle, where the battle was most intense.

Zhao Yu did not see the battle situation here, but he saw the corpses of enemy soldiers on the slope of the hill from the front of the position to the foot of the mountain less than 100 meters, and the dense arrows like thorns on the position and the pools of congealed blood in the position, he knew the intensity of the battle here. He turned over an enemy corpse that had fallen in front of the position, and on its chest was clearly a triangular wound pierced by a bayonet, indicating that there had been hand-to-hand combat between the two sides, and that the enemy had broken through the fire barrier and rushed into the position.

"Your Majesty, we have suffered more than 100 casualties on this position, accounting for almost half of the casualties of the Second Brigade!" Li Zhen said in the foreword.

"Well, our muskets have a long range, great power, and a thunderbolt to enhance the firepower, the enemy can still inflict such heavy casualties on us, we must investigate clearly and learn from it!" Zhao Yu nodded with a heavy face and said to everyone. He knew very well how difficult it was to train a qualified soldier, and that every soldier's sacrifice was an irreparable loss, and although it was inevitable, it was always good to sacrifice less......
