After many battles of the destruction of the Jin Dynasty and the Western Expedition, the Mongolian cavalry obtained a large amount of property, weapons, armor and captured the skilled craftsmen of various countries, making it possible to develop heavy cavalry. They created their own full-equipped heavy cavalry, and their proportion in the cavalry also increased. A team of 10,000 people can reach about 40%, becoming a main force of Mongolian cavalry.

Therefore, Zhao Bing was not surprised when the Mongolian army dispatched heavy cavalry to attack. For many years, in order to defeat the Mongolian Yuan and restore the hometown of the Song Dynasty, he was constantly seeking ways to break the enemy. As the Song army completely replaced the firearms and the fact that it was difficult to change the lack of horses for a while, he made tactical changes around the existing muskets and artillery, and now gradually formed a model of muskets and infantry as the output and cavalry were responsible for covering.

In addition to muskets, in order to make up for the insufficient firepower output, Zhao Bing also invented a variety of artillery, formed a special artillery force, and continuously optimized it. In order to make the heavy cannons move better, he used the experience accumulated in actual combat and production to reduce the length of the artillery barrel without reducing the power of the artillery.

In addition, Zhao Bing changed his past use of single-line horse pulling to double-line towing. In this way, using six horses, he could drag a heavy gun truck that could fire ten kilograms of shells, four horses to drag a medium gun truck that fires six kilograms of shells, rocket launchers, or Flang machine rapid-fire cannons. The gunners also equipped with more convenient shoulders for "being a cow and making a horse", which gave the equipment guns a strong maneuverability.

At the same time, Zhao Bing installed iron axles and strong large-diameter wheels on the cannon truck, which greatly increased its traffic capacity and could travel on rough terrain. He guided the firearm workshop to create more precise orbs and precise diameter shells, ensuring the range and accuracy of the cannon, and reducing the loading of the cannon, which further reduced the weight of the cannon barrel. In addition, Zhao Bing also replaced the past separation of ammunition and bullet barrels with prefabricated cartridges, and used a layered ruler and gun body adjustment device to increase the firing speed of the French gunners, thereby further increasing the firing rate of the shells.

"Your Majesty, General Ni Du asked for an order!" Tan Fei saw the flag uttered by the chief general and stepped forward to report.

"I have granted him the right to make an opportunity, so I can let go of my command and do not ask for instructions!" Zhao Bing still looked at the battlefield with a telescope and replied in a deep voice.

"Yes!" Tan Fei immediately ordered Guan Tong to reply. After thinking about it, he asked his guards to send orders to strengthen the alert, and transferred the personal guards to set up defense lines in front of the building.

"Are you nervous?" Zhao Bing lowered the telescope and turned around and asked Tan Fei.

"Well, I'm a little uneasy!" Tan Fei nodded and did not deny it.

"Haha, this is the first time our army has faced such a large-scale rushing scene, and I am the same!" Zhao Bing smiled and said without hiding his nervousness at all.

In Qiongzhou, due to the limitations of combat methods, the Mongolian army invaded several times with sea as the main battlefield, with limited enemy cavalry that could land, and the fundamental opportunity to launch a large-scale attack; in the battle of Quanzhou, the enemy cavalry, mainly Han army, had limited military strength, that is, a thousand-man charge; and in the battle to recover Jiangnan, the largest anti-cavalry combat was in the imperial tomb area, but the Song army occupied favorable terrain and built complete defensive fortifications, making it difficult for the enemy cavalry to launch such a large-scale battle.

Therefore, in the face of the battle between tens of thousands of cavalry, not only Zhao Bing was the first time, but everyone was also like this. In fact, no one had any confidence in whether he could withstand and whether he could win. But he felt that everything would be the first time, and all units had been practicing to fight the impact of the enemy cavalry and relying on the military camp to defend it. The terrain was also not conducive to the performance of the enemy cavalry, which still gave him the confidence to attack.

"Shishuai Ni Dushuai, why didn't he order artillery firing? The enemy cavalry is almost under his nose!" Wang Yinglin watched the brigade of enemy cavalry roaring overwhelmingly approaching quickly. Our frontier infantry retreated and had already given up his position for the artillery, but did not fire and fire. He couldn't help but become impatient and patted the railing.

"Governor Wang, don't be anxious. Just attack the front team and cannot curb the enemy's charge. Only by breaking up the rear team can the enemy's attack be defeated!" Zhao Bing said.

Zhao Bing knew very well that the most commonly used combat method used by the Mongolian army during attack was to line up the troops into many roughly parallel columns under the cover of light cavalry and advance in a very wide line. When the first column encountered the main force of the enemy, the column either stopped moving forward or retreated slightly according to the situation. The remaining columns continued to advance and occupied the enemy's side and behind the enemy. This often forced the enemy to retreat to protect its traffic line. The Mongolian army took the opportunity to approach the enemy and made it become chaotic when retreating, and finally surrounded the enemy completely and completely annihilated it.

When the Mongolian Army rushed to the formation, the standard combat formation was composed of five horizontal teams, each horizontal team was single-rowed, and each horizontal team was very wide apart. The first two horizontal teams were heavy cavalry, and the other three were light cavalry. While it was able to maintain mobility, the front and rear teams could interspersed and changed the formation at will. In addition, there were also some light cavalry units responsible for reconnaissance and cover.

As the troops of both sides of the enemy get closer, the three light cavalry located behind will advance through the gap between the first two heavy cavalry, and after careful aiming, they will project devastating javelins and poisonous arrows to the enemy. Then, while still maintaining the formation in order, the first two heavy cavalry retreat first, and then the light cavalry retreats in turn. Even if the enemy's front is stable, it will be shaken under this prepared dense arrow attack. Sometimes, this kind of harassment can cause the enemy to collapse and there is no need to charge assault.

If the column commander believes that the preparatory attack has completely disintegrated the enemy, he will order the light cavalry to retreat. However, if the need is required, he will order the heavy cavalry to launch a charge. However, if the troops located in the center have exchanged fire with the enemy, the two wings will disperse to the flanks and circumnavigate to the sides and back of the enemy. When carrying out this encirclement, the enemy often use smoke screens and dust to confuse the enemy, or use the cover of hills and valleys. After completing the siege of the enemy, the troops will launch attacks from all directions, causing chaos in the enemy's formation and finally completely defeat the enemy.

The siege movement is a common combat method used by the Mongolian army, and they are particularly good at using strategies to implement this tactic. However, due to the change in combat methods, the Mongolian army cannot lose Yangzhou, so strategically speaking, it is actually in a defensive position. In addition, the terrain is limited and the combat area is small, which makes them unable to exert their advantage of strong maneuvers. Using the tactic of large detours on both wings, they can only retreat to find a way to concentrate their forces on the front battlefield and conduct head-on combat methods.

"Fire the cannon!" Seeing that the enemy cavalry was getting closer, it was indeed as if it had begun to change formations in the past. The light cavalry on both wings began to slow down, and the heavy cavalry behind them penetrated out of the reserved gap and accelerated toward their own defense line. At this time, all the enemy cavalry entered the range of artillery attack, which was the best fighter. Zhao Bing couldn't help but roared, as if he was commanding at the forefront.

‘Boom, boom, boom…’ Ni Liang, who was in front, issued an order to fire artillery almost at the same time as if he had a close relationship with the little emperor. Liu Ming, the commander of the artillery brigade, placed the flag. In the artillery position arranged in a staging, the rocket regiment and the heavy artillery regiment were the first to fire. The position was instantly covered by gunpowders, and only the flames ejected from the muzzle and the bright bullet marks of the rockets were seen.

Then the rocket group was the first to explode in the enemy's rear army, and clouds of smoke rose up. The surrounding enemy cavalry immediately fell into it, and less than half of the enemy cavalry could struggle out of it. Although the flowering bombs fired by the artillery were not as gorgeous and shocking as the rockets, they also exploded with huge sparks after landing. The broken shrapnel mixed with the bursting soil and stones splashed everywhere, and they shot out in a radial shape. Within twenty steps, people were instantly tilted, either dead or injured.

"Huh..." Zhao Bing breathed a sigh of relief. With the roar of his cannons, the fighting spirit of the Mongolian Yuan cavalry began to be chaotic, and the war horses were suddenly frightened by the sound of artillery. However, the Mongolian army was an elite soldier who had been through many battles. Although its combat effectiveness was no less than before, its foundation was still there. In the gap after the first round of artillery bombardment, officers from each unit quickly gathered their respective troops, adjusted their formation, and continued to rush towards their own side.

"Ah..." Seeing that the enemy was only bombarded by artillery fire, there was only a brief chaos, and he didn't even get off the horse. While running, he adjusted his formation and rushed over again. Wang Yinglin, who had become excited when he saw the power of his own artillery group shooting, became nervous again and said in a daze.

‘Boom, boom, boom…’ When the enemy cavalry was still two hundred steps away from its own position, the rapid-fire cannon arranged in front of the central army began to show its power. The rapid-fire cannon's shotgun loading tube contains fifty small projectiles, which scattered fifty steps away from the muzzle under the urge of gunpowder. The distributed fan surface is dozens of steps. Of course, the longer the distance, the larger the area it spreads. Although the distance is far, the power of the small projectiles that can be shot remains unabated, even half an inch behind the iron plate can penetrate. Although the equipment of the enemy heavy cavalry is covered with chain mail and the outer iron leaves are spliced ​​with layers of armor, they are also penetrated instantly, which is exactly the saying that "there is a complete armor under the firearm."
