The grid paper is lined with chess-like ceramic pieces, representing musketeers, pikemen, and artillerymen.

Some battalion commanders and company commanders were moving chess pieces representing various arms of the armed forces according to the preset battle conditions, while others were listening to Company Commander Li Yun preach his military philosophy. "We train our troops to move forward in a staggered way, which takes at least nine months. And where is the terrain on the battlefield so many flat ground that allows us to calmly set up the formation. So let's turn the big phalanx into small phalanxes. ”

The five battalions that came this time have all fought in battles, and they can become company commanders, complete the process of studying subjects and participating in battles, and all of them have basic command ability. In the previous battle, everyone had enough of the hardships of arranging formations on those muddy lands, and the land in the Yangtze River basin outside the window had not changed much compared to the cities of Jiaozhi.

Seeing that no one objected to his opinion, Li Yun continued to say to the commander who was listening to the class: "As the captain said, there are two main points for doing this. Artillery must be able to move faster, and platoon commanders of various units must be able to command their troops better. The artillery was already doing an excellent job, and now the point is whether the platoon commanders are qualified or not. ”

Young people eagerly express their opinions, unaware that they are challenging a major military problem. The higher the military level and the stronger the military capability, the higher the requirements for the more grassroots soldiers. For example, the PLA, which is at the peak of infantry, is divided into three-person combat teams in a squad. Now Li Yun and others are challenging each platoon commander to arrange their own platoon's actions according to the terrain and other conditions, which is really ahead of its time in this era.

Li Yun and they did not have a precise positioning of themselves, the reason why they did this was very realistic, after the large phalanx was arranged, it was very likely that they would be invincible on the plains, but where were there so many plains for the army array. Spain, which rose to prominence with a phalanx of firearms, is a semi-desert region, and dense water networks are not the norm in Europe. Since you don't want to give up the advantage of the large army formation, you have to adjust it according to the terrain.

While he was talking, a messenger came to report that the Mongol army had been found in front, and the number was about 3,000. The internal military meeting ended temporarily, and the battalion commanders and company commanders rushed back to their units to begin preparations for combat. The follow-up intelligence of the Song army showed that the Mongol army did not appear on both sides of the canal, but all of them were located on the east bank of the canal and set up a position, seeing that they meant to threaten the flank of the Song army.

Looking at this arrangement, Li Yun wondered if the generals of the Mongolian army had not woken up. There was no need for him to say what to do, and the troops had formed a two-story array along the side of the canal in companies according to the pattern they had trained many times before. The artillery lined up in the front line, covering the area where the flotilla behind passed through the area of the Mongol formations by alternating cover rolling forwards.

Li Yun didn't know that the general who 'didn't wake up' on the other side was a 17-year-old hairy doll. This doll's name is Boyan Cha'er, and it is a horse of the Mongol Dynasty. From Boyan Cha'er's point of view, it is really normal to put on an assault formation. Fighting with their backs to the water, they simply couldn't cover such a long fleet.

The Mongol army would not fail to observe the enemy's disposition, and according to the accurate reconnaissance of the Mongol probes, Boyan Cha'er determined that the Song army had put on an incomparably slender formation. Although he didn't know if there was anything expensive in the Song army's brain, the brave horse master seized the fighter plane and commanded 3,000 soldiers and horses without hesitation to launch an attack on the Song army's battle line, which was broken at the slightest poke.

For such a textbook battle, the Song army calmly coped with it. The troops sent this time have been reorganized, and each battalion is still seven companies, but there are two artillery companies, three pikemen companies, and two musket companies. An artillery company has six two-pound guns, and a battalion has twelve two-pound guns. At this time, the Mongolian army was facing two battalions of Song artillery, as well as an additional artillery company sent by Battalion Commander Li Yun.

Five companies of 30 two-pound guns calmly bombarded the advancing Mongol army, and each round of shelling caused more than 30 casualties. Boyan Cha'er was very brave, and instead of staying with the infantry in the back, he commanded the cavalry to rush over. At this time, the precipitation in the canal basin had not yet made the ground muddy, and the cavalry of the battle for merit galloped along the road in the paddy fields.

There was no need to even arrange them, the Song musketeers only had to block the road and hail the rushing cavalry with a dense rain of bullets. The Mongol cavalry was led by horses on several narrow passages, and more than forty horsemen were knocked down, and the cavalry who were not killed saw that something was wrong and immediately retreated. During the retreat, more than two dozen people were knocked down.

To be a Mongolian horse, you have to have the pride to look down on life and death, and do it if you don't accept it. Otherwise, you will be looked down upon. I have to say that the master of the horse is the master of the horse. Boyan Cha'er, who was carried away by the young blood, was still able to gather the cavalry, forcing them to charge again.

This time, the horse master held his saber tightly and charged with the other Mongolian cavalry. Listening to the dense howling sound from the direction of the Song army, and listening to the cavalry and war horses in front of him and to the left and right screaming or neighing. The wind was blowing in his ears, and he knew that as long as there were cavalry that could break through the enemy's thin array, he could crush it. All that is needed now is to use the speed of the horses to do it.

Then the horse under the crotch of the horse suddenly neighed, and the front hooves fell down as soon as they became weak. Fortunately, the young horse master was light, and at this time he actually held down the saddle for a leap, and after falling to the ground, he ran forward a few steps, and then stood firm. The horse master, who was so confused by the sudden change that he didn't know what was going on, looked back and saw that only a few horses of the more than forty cavalry who had attacked with him were left and rushed into the rice field frantically, struggling to escape in the mud.

Turning his gaze to the infantry array further back, Boyan Cha'er saw that the infantry had fled under the artillery bombardment. On the opposite side were no more than thirty guns, and three thousand infantry turned around and ran away under the bombardment of thirty guns.

At this time, the gunfire stopped, and the horse instinctively felt the danger. When he turned his head to look, he saw that the pikemen of the Song army raised their guns and killed him. Raising his saber, the horse master wanted to continue the fight. However, looking at the other party's four-meter-long spear, even the brave horse master felt great fear. At this moment, a personal soldier suddenly rushed up behind the horse master, he didn't care about thirty-seven twenty-one, he pulled the horse master and ran back.

Although the Song army wanted to leave the enemy behind, the situation was embarrassing after the infantry was released. They blocked the musketeer's view, and the horseman, who was faster than a rabbit, reappeared in the musketeer's field of vision, and the distance between the two sides was beyond the range of accurate shooting. At this time, whether or not you can hit people after shooting depends on the will of God.

The master didn't know that he had escaped, and he was pulled by his own soldiers. The two men ran past the area of the dead and wounded and continued to run violently, almost catching up with the Mongol infantry who had begun to flee before they could almost vomit blood. At this time, the two of them couldn't run anymore, and Boyan Cha'er turned his head to see where they had fled before. From a distance, I saw some of the Song army's spearmen chasing the wounded who were wounded in the shelling, and when they caught up, they were stabbed to death. Some did not continue to pursue, but only assassinated the wounded Mongol soldiers who fell to the ground.

The pikemen did not chase down one of them, and when they were almost done, they closed their ranks and returned. Looking at the thin line of Song army arrays in the distance, covering the long line of ships lined up behind them and continuing to move forward, the horse master was sad and cried bitterly. After all, he was only a seventeen-year-old child, and his subordinates had suffered such a big loss, and the more he cried, the more sad he became, and he simply fell to the ground crying and rolled around.

Compared with this seventeen-year-old woolly doll horse, the twenty-three-year-old battalion commander Li Yun is much more mature. Battalion Commander Li calmly and calmly commanded the troops to kill all the Mongol soldiers they could kill and gather the horses. Although he was intolerant of the killing of the Mongol soldiers, Battalion Commander Li was much more tolerant of the horses, and tried to save those who could be saved, and only killed those who could not be saved, skinned and cut the meat.

As the troops continued to advance, Battalion Commander Li Yun discussed the gains and losses of the battle with other battalion commanders. He came up and made self-criticism, "I had a problem with my calculations before, if only there were three artillery batteries in each battalion." ”

Other battalion commanders agreed. The weakness of the Mongol army in the face of artillery made everyone inclined to use artillery to solve the enemy's tactics. If the French generals of the Napoleonic era heard this, they would probably be angry, and the French army only gave 4 guns for a battalion of 1,000 people. A division of 9,000 people and 36 guns only. Of course, the French artillery of the Napoleonic era was six-pounder guns, and the infantry weapons also surpassed Li Yun's troops in an all-round way.

The defeat of the horses gave the transport troops more than a day's time. They were originally less than 100 miles away from Yangzhou, and this day they walked 60 miles peacefully. Seeing that it was only 30 miles away from Yangzhou, the troops slowed down and prepared.

Marshal Ashu did not disappoint everyone, and he mobilized more than 10,000 troops besieging Yangzhou the next day to meet the grain delivery troops.

The two sides didn't do any tricks, they just pulled out the array and hit it hard. The Song army was the old routine of artillery in the front line, and pikemen and musketeers lined up behind the artillery. The Mongol army has some new ideas, pushing up long-range projection weapons such as bed crossbows on the front line, and slightly back are the crossbowmen of the new annex army. The total number is about 3,000.

Three thousand men against sixty guns, the battle between the marshal and the commander of the Maotou battalion began with the sound of an arrow.

Ordinary people only need to be hit by a bed crossbow and shoot a huge crossbow arrow to immediately reimburse their lives, and the effective killing range of those foot crossbows is more than 100 meters. As a rain of arrows poured down on the sixty-gun position, the poor gunners could only huddle behind cast-iron cannon shields and open fire.

Like a storm slapping on the wooden door, the metal arrows shot on the cast iron cannon shield and made a crackling sound, and the associations brought by this sound made the Song soldiers behind the cannon shield tremble unconsciously.

Even more pitiful than the poor gunners were the gunners who had to clean the chambers and reload gunpowder. The gunners had cast-iron gun shields to hide, and these gunners had to be exposed to their bows. Even with a cast iron helmet lined with thick cotton on the headband, cast iron armor on the back, and a thick layer of paper armor on the outside, these gunners turned their backs to the enemy, muttering and doing what they had to do. Looking from the side of the Mongolian army, there are always some porcupine-like figures that have been shot by arrows next to the Song army's artillery emplacement.

"Fight well, hurry up and kill all those Mongols." The porcupine-like crew was doing their job while being ruthless at those who fired behind the shields. Everyone is basically in such a situation, and everyone seems to have no other way but to do everything possible to increase the rate of fire.

The rate of fire of a gun is largely limited by the heat dissipation of the gun, and the gunpowder gas of each shell increases the temperature in the barrel. Even if the barrel is brushed with water, once the temperature of the barrel after the water has evaporated is higher than the natural temperature of the remaining ash residue, and new gunpowder is filled into the barrel, the result is tragedy. Such a tragedy occurred in Zhao Jiaren's unit during training.

Cast iron cannons with gray iron are thinner than those with white iron, which means better heat dissipation. It looks like an inconspicuous gap, but in the actual battle, it is not at all like that. As long as the frequency of point firing was reduced and the intensity of watering and cooling was increased, Zhao Jiaren's artillery was able to maintain continuous fire for a long time. The artillery crew of the Song army withstood the enemy's dense rain of arrows and maintained the frequency of about two shells fired by two catties of artillery in one minute.

Compared with the anti-arrow means of the Song army's artillery crew, the Mongolian army had no means of defense against the two-catty cannon at all. Each round of sixty shells flew by, and the long-range units of the Mongol army could not find any other means of defense except for the words in their mouths.

Gradually accustomed to the rain of arrows beating the cannon shield and the porcupine-shaped Great Song artillery, the cannon is getting smoother and smoother, but the long-range troops of the Mongolian army on the opposite side are not used to being unprotected against the shells that will die after being hit. As the ranks began to thin out a little in the screams, even with the Mongol sword and axe men and the northern Han army watching, the 3,000 long-range troops held up a full ten rounds of artillery bombardment before finally began to retreat to the position of the Song artillery in great strides.

Marshal Ashu did not order the swordsmen to slash these ranged troops, for he could see that even the Mongol archers and the Song army would have the same result. If you are more realistic, this new annex army performed much better than the Mongol army under the solidity of the sword and axeman.

Generally speaking, the Song army will be much more passive than the Mongolian army, and will watch the Mongolian army adjust dumbly. Battalion Commander Li Yun is the battalion commander of the Song Army founded by Captain Zhao Jiaren, and his attitude is to take advantage of your illness to kill you. Since the Mongol army had no way to deal with the artillery bombardment of the Song army, as the long-range troops of the Mongol army retreated, the Song army pushed the artillery forward. At a distance where the Mongols could not immediately counterattack, they continued to fire at the Mongols.

This time, the first to suffer from the shells were the axemen. With the range of their attack, this is already a complete one-sided beating. So the axemen took only two rounds of artillery fire and immediately retreated. Marshal Ashu knew that this was a taboo in the army. The army is most afraid of chaos, and the ranged troops and the axe men have no desire to fight again at this time, and there is no way to force them to continue fighting immediately. If it is forcibly adjusted, it will immediately be a big mess on its own front.

The marshal had to order the Mongol army to retreat first. When Li Yun and the others saw that Marshal Ashu's troops had also withdrawn from the shore, they immediately changed their troops to a slender covering formation. Not long after, the troops crossed the area once guarded by Marshal Ashu and continued to advance towards Yangzhou.

Seeing that the Song army changed formations in an orderly manner and advanced in an orderly manner, the marshal did not give the order to continue the onslaught. That night, the Song army, which escorted a total of 45,000 stone of grain, entered Yangzhou. Yangzhou City received enough food to hold on for another half a year.
