When the Xian army stabilized its position from the attack, followed by the neighing of war horses, the sudden tremor of the ground made Bai Liyan realize that the cavalry of the guards had launched a night attack, and it should be from the left flank, relatively speaking, it was the right flank of the northwest defense line of the Xian army along the river, where was the junction of the Xian army and the river bank, if the guards tore the hole, the line of the Xian army would be completely broken.

"Wei Qi, the cavalry of the guards wants to attack our right flank, quickly order the second line of defense Zhou Deyan to go to the right flank of our army to fortify twenty steps, and order the reserve to fill the gap in Zhou Deyan. If the enemy breaks through the defensive line, immediately gather his troops and horses and block the enemy cavalry. ”

"Obey the order, lieutenant!"

Night raids and heavy rain were even more unfavorable to the infantry, and the night raids of the cavalry were even more so, the Xian army landed on the shore and repaired for a day, and did not build camps and fortifications decently, so they could not stop the surprise attack of the cavalry of the guards.

The thin line against the cavalry onslaught, even though equipped with bayonets and advanced firearms, was extremely detrimental to the infantry in this dark night with a rainstorm and obstructed vision.

A series of orders were not issued for a long time, the right flank first heard dozens of neighing sounds of people on their backs, and then the gunfire was loud, the right wing of the Xian army took the lead in firing, firing a volley, the guards launched a charge at the same time, the Xian rifles and shotguns took turns to shoot alternately, the guards cavalry fell in pieces, the guards cavalry killed in front of the fire, and the straight horse lance pierced into the chest of the soldiers of the Xian army, and the two armies met head-on.

The length of the horse lance is more than two meters five or even three meters, and the rifle of the Xian army is less than one meter eight after the bayonet is lengthened, and the horse lance rushed in front of him cannot reach the cavalry of the guards at all, and the close combat is extremely disadvantageous.

At this time, the right flank immediately fell into a melee, Bailiyan immediately divided the right flank from the main formation, and ordered the Xian army on the left side of the right flank to surround and move forward, and the Zhou Deyan Division, who was about to arrive, would re-establish the defensive line twenty steps behind the right flank and collect the retreating Xian army.

The biggest advantage of cavalry is not riding a horse, but the speed and mobility of a horse to sprint, and more importantly, the cavalry has room to maneuver.

The speed of the cavalry of the guards rushing into the array of the Xian army was greatly weakened, and if they wanted to recover the speed of the sprint, they needed an impact distance of more than 200 meters, and it was not good for the Xian army when it was dark, and it was also unfavorable for the regrouping and dispatch of the guards.

Once it loses its speed and mobility, it can break through the right flank in the tightly organized Xian army's defense line, but it will also lose its maneuver space due to the loss of speed, and will eventually be compressed and eliminated by the Xian army.

At this time, the gunfire was loud, and it reached the ears of Du Ruixun behind the main formation of the guards, and the binoculars could only see the fire on the right wing of the Xianjun army, but he couldn't figure out what kind of weapons the Xian army used, but after careful thinking, Du Ruixun vaguely guessed that the Xian army was equipped with some kind of individual firearms, which made him think of the rope hat gun equipped by the guards.

"It's unbelievable that the Xianjun army also has a rope cap gun."

Protector Wang Xie was taken aback when he heard the news:

"But in the secret reports for many years before, there was no news that the Xianjun army had made rope guns, so how could the Xianjun get rope hat guns."

Du Ruixun sneered and said:

"Huh...... The Xian country is unpredictable, with its iron-smelting productivity, it is not difficult to make a rope hat gun, and I don't know how many secrets the Xian army has hidden from the outside world. If this is the case, I am afraid that we will fall into a bitter battle in the future. Pass my generals, the three generals Chu Lie, Gao Kan, and Qin Shuo in the front line attacked, and the rope hat gun and flat hand cannon were withdrawn immediately after a while, and at the same time, the overlord cannon pushed me up. ”

"The last will be ordered!"

While the cavalry attacked the right flank of the Xian army, Du Ruixun immediately launched a fierce offensive from the northwest front, planning to defeat the Xian army on the northwest front in one fell swoop after breaking the Xian army's battle line, not giving Bailiyan a chance to breathe at all.

Rope hat guns and peace hand guns are all "new and advanced" firearms that have been developed by various countries in recent years. Among them, the flat hand cannon is a kind of fire gun inserted into a wooden pole, with a cast copper gun at the front, ranging from 25 to 30 mm in caliber, and filled with projectiles or iron sand. There are also larger calibers that can be loaded with poison smoke and jet flames to kill enemies at close range.

The rope cap gun is an "extremely advanced" firearm at the moment, which still uses shoulder-mounted firearms, but is equipped with a wooden bracket at the front end, which can be carried on the shoulder and squatted to shoot. The fire door is still at the tail, but there is a barrel-shaped copper cap flap on the fire door, and the flap is infected with oil and animal oil wax with cotton wool, which is ignited when used, and the user only needs to pull the rope on the shoulder to press the flap against the fire door to fire.

After learning about the "rope hat gun" earlier, Baili Yan once made the royal guest stunned after stealing the research.

Although this type of firearm is rudimentary, the flap is extremely reliable, the fire is retained for a long time, and there is no need to constantly adjust the length of the arquebus, as in the case of arquebuses. same

When because of the oil mixed with animal fat to make the fire, the flame is not easy to extinguish, even if the heavy rain is pouring, it is difficult to extinguish, the reliability is very high, the basic realization of one person to operate the loading and firing, has a certain practicability, and is more reliable and practical than the arquebus.

Ignoring the efficiency issues brought about by the limitations of the current technology itself, this kind of firearm is already very advanced under today's technical conditions.

However, this kind of firearm is a cast product after all, and due to the backwardness of pouring technology and smelting technology, it is destined to increase the weight of the firearm at the expense of the pipe wall to increase the weight of the firearm.

And in order to increase the firing range and the power of the projectile, the length of this shoulder-mounted rope cap gun is half a zhang, which is a typical long-barreled weapon, and its casting molding rate is not too high, not enough to popularize a large number of people, and its weight is up to forty or fifty pounds, and it needs to be propped up at the front end to launch when firing, and the effective range is less than 70 steps, and the accuracy is basically made up by density.

In addition, when the fire door is loaded to the ground, and the flap is lifted to land the fire, when it is lifted again, the fire copper is sagging and swinging, and it is easy to hit the fire door to cause a fire, so there is a ring at one end of the rope that implicates the fire copper cap when loading, and the ring is buckled on the convex hook fixed on the side of the firearm, so as to tighten the fire copper rising, and release the rope when firing.

Although the rope cap structure ensures the firing rate and firing reliability to the greatest extent, it is difficult to reload in heavy rain because the fire door needs to be hit on the ground for reloading.

Du Ruixun was well aware of the shortcomings of the rope hat gun, and he needed to withdraw to the main position to reload after a rope gun and a flat gun fire, but in order to ensure the output of firepower, the guards explored the strategy of alternate shooting through the actual combat on the front line.

At this moment, the right flank of Bailiyan was rushed by the cavalry of the guards, and before the right flank was reorganized, the cavalry on the left flank of the front of the guards launched a second round of impact, and at the same time, the guards in front of the front began to move rapidly towards the front of the Xian army.

"Du Ruixun is worthy of being Du Zhen's son, I'm afraid I'm going to be in trouble this time!"

Secretly said in her heart, Bai Liyan realized the horror of Wei Jun and Du Ruixun.

There is an important principle in the use of troops, both ancient and modern, and due to the constraints of the command system and communications, the width of the battle line and the scale of troop input are limited, and this is especially true for fighting at night and in rainy weather. In order to facilitate command and dispatch, it is impossible to accumulate a large number of troops on the front line, nor can it launch tens of thousands or even hundreds of thousands of people to attack the enemy at the same time.

Therefore, in a life-and-death battle, the power output of the attacking side must be maintained with a certain amount of strength and ensure its continuity, unless necessary, the waves cannot be interrupted, and must be consistent, or one wave stronger than the other, constantly projecting troops to keep the enemy busy defending and fighting to the death, until the place is exhausted and the will to fight collapses.

Any unnecessary interruption of the offensive for no reason may waste the lives of the soldiers in exchange for the battlefield situation, and it is a major test of the commander's ability to command, dispatch, and respond to changes on the spot; in a battlefield where the situation is changing rapidly, the slightest hesitation or interruption may change the course of the war, and the commander can only make every decision in a dynamic environment.

However, due to the constraints of the times, the dissemination of knowledge is extremely limited, and the number of educated people is even smaller. The cultivation of military talents by the princes of various countries is still stuck in the two paths of familialization and meritocracy, and there is no way to talk about the construction and training of specialization and systematization.

Therefore, the ability of most commanders and generals is very mediocre, even mediocre and incompetent, and many people are unable to control the intensity and frequency of their troops, let alone grasp the fighters and use tactics to deceive them, and to strategize and coordinate logistics.

Du Ruixun is just a rare good general to defend the country, and the mantle he inherited from Du Zhen, the so-called tiger father without dog son, is often the inevitable result of the lack of education and material "resources", because only the elite class can really contact the books of the current class. At present, the book of war is even a national secret, and it is not the core knowledge that ordinary people can access at all.

After some fighting, Bai Liyan could already see that his troops were quite powerful, and he didn't intend to give the Xian army a chance to breathe.

At present, before half of the night in the first half of the night, it is attacking the northwest defense line of the Xian army in batches, and the firepower is constantly output, obviously trying to transfer the main force of the Xian army and disrupt the existing deployment of the Xian army.

In the second half of the night, the Huwei River Guards arrived and put into battle, and the western front of the Xian Army was involved in the battle on the right flank, and the strong rear was completely exposed to the front of the guards. Rifles that can only be loaded with one bullet have been greatly weakened at this time.

In the face of Du Ruixun's wishful thinking, Baili Yan could only slam the grenade and wipe it out as much as possible thirty steps away.

In the night, the firelight came and went, the sound of explosions was endless, the Xian army began to fire volleys in turn, the guards went through the baptism of war, the cognition of firearms increased greatly, and in the face of the violent sound and light reaction, the psychological tolerance value of the guards increased significantly.

At the same time, in the battle with the eldest grandson, the guards had already figured out a way to deal with the eldest grandson's rope hat gun, they bent down, bent their calves to press their heads, walked quickly, and when they got closer, began to turn their heels or crawl on the ground, so as to avoid the projectiles fired by the rope hat gun. Instead of relying on the bloody courage of the above, they formed a dense formation and launched a charge with a dignified chest.

Seeing this scene, Bai Liyan couldn't help but feel ashamed:

"Unexpectedly, the guards also figured out the evasive tactics of low-profile advancement."

As soon as the words fell, Wei Qi came to report:

"Deputy Marshal Qiyu, the Huwei River Guard Army is fifteen miles away from our army."

"Got it......"

Halfway through the words, a burst of dense gunfire came, Baili Yanmeng was taken aback, and looked fixedly, the Xian army fell, and the front of the guards was filled with smoke, and he subconsciously thought that it was the guards' flat hand cannons and rope cap guns that were close to fire.

"Damn, order Xue Sheng, transfer all the grenade launchers on the western and southwest lines to us, and order the grenade launchers to shoot their own guns thirty steps away, but if they find the overlord cannon of the guards, they will be destroyed first."

"Subordinates obey!"
