After two volleys of fire from the immovable battalion of the Tuanshan Army, the Swiss mercenary regiment had continuously fired four rounds of muskets, and it was obvious that the casualties of the immovable battalion on the field were greater than those of the enemy.

But the immovable battalion did not flinch, and continued to reload and shoot in order, allowing a wave of soldiers to fall, and not a single one of them had a look of fear on his face.

Zhang Li was very concerned about the situation on the battlefield, but now he couldn't see the specific situation. Because now he is a little behind the Chinese army, he did not choose a high ground to build a "former enemy command post" as in the past. There was only a few hundred guards around Zhang Li, and Zhang Li sat on a marching bench, calmly listening to the scouts' reports.

This is equivalent to clearly telling the 30,000 regimental mountain army soldiers present that Lord Zhang does not intend to be an outsider in this battle, he will move forward if the army goes forward, and if the army retreats, he will stop at the end to see who dares to retreat!

The scouts shuttled back and forth among the melee army, and although they couldn't see it, Zhang Zhang also knew the enemy's tactics from the scouts.

Zhang Zhang muttered to himself: "Three-stage shooting......"

Kang Xing'an looked anxious, frowned and said to Zhang Li: "My lord, the enemy's three firing firepower is non-stop, and the immovable battalion is now suffering a lot!" ”

Zhang Li's face was as usual, he glanced at Kang Xing'an meaningfully, and said lightly: "I have known this tactic for a long time, and it was once blown into the sky by Little Japan, but it is actually destined to be eliminated." Wait and see, and that should change. ”

Historically, Oda Nobunaga, the great demon king of Japan's Warring States Period, defeated the cavalry of the Takeda family in one fell swoop with the "three-stage attack", thus establishing the general trend of the unification of the "world Buwu". Japan's Warring States are a bit like the Three Kingdoms, Oda Nobunaga is roughly equal to Cao Cao, while Toyotomi Hideyoshi can be equated with Sima Yi, and Tokugawa Ieyasu, who eventually unified Japan, is Sima Yi after "Sima Yi". The changes in the interims are even more than those of the Three Kingdoms.

This "three-stage attack" tactic first appeared in the Hongwu period of the Ming Dynasty, but it is not necessarily that the Ming Dynasty spread to Japan. Because such tactics were also used in Europe at the same time. In the arquebus era, this was indeed an advanced tactic, and it was extremely lethal to enemies using cold weapons. However, the times are advancing, and the "platoon gun" tactics used by Zhang Li now are the advanced tactics of the 17th, 18th, and 19th centuries of world domination, and they will certainly be better than the "three-stage strike".

It's just that the current situation seems to be a little bad, and the casualties of the non-moving battalion of the regimental mountain army just now exceeded that of the enemy!

Wood commanded the immovable battalion to methodically continue firing at the enemy. This kind of battle is very boring, you shoot me, I shoot you -- it is far less fancy than "taking the head of the general in the chaos of the army", but it is extremely testing the will to fight of the immovable battalion.

Of course, this is not the later Makqin or any AK47, whether it is the enemy's flintlock pistol or the rifled gun of the immovable battalion, the accuracy is at the "heh" level, which is one word less than the "hehe" level of the arquebus. If you really hold an AK47, no matter which side of the battle is facing it, it will not be tenable......

Now the fire gun kills by luck in the first place. The second place is the intensity and continuous blows.

After just three volleys, the Fudo battalion now suffered more than a fifth of its casualties, and about six hundred people fell. More than half of the soldiers in the last column have been added to the first two columns, and if there are a few more volleys, then the last column will disappear completely!

It seems that the battle also began according to this script, and after a new round of salvos from the Swiss mercenaries, more than 200 people fell in the camp of the Tuanshan Army!

From the very beginning of the war, Wood's eyes were fixed on the Swiss mercenaries on the opposite side. Didn't leave for a moment. No matter how many casualties the soldiers of the Immovable Battalion in front of him were, he never looked away.

At this time - at this time. A gleam flashed in Wood's eyes, because there was a situation in the Swiss mercenary front on the opposite side that Zhang Li said!

Smoke!

Due to the continuous firing of the "three-stage shooting", the density of the gunpowder smoke became more and more dense, and it was not obvious at first, but with the increase in the number of salvo rounds, the speed of the gunpowder smoke produced far exceeded the speed at which the gunpowder smoke dissipated!

This is before the invention of smokeless gunpowder. The fatal flaw of the "three-stage shot"!

In the past, the "three-stage shooting" was used against the enemy with cold weapons, and the enemy did not put much pressure on the musketeers, who could shoot a few rounds and rest for a while, and this was indeed the case. Whether it was to cope with the charge of cavalry or the charge of infantry. Absolutely no one can make a steady charge in the dense and non-stop sound of fire.

Therefore, the defect of too dense gunpowder smoke is not particularly obvious.

However, the musket shooting of the Tuanshan Army's immovable battalion was different, and from the very beginning it put great pressure on the opposing musketers. They had to shoot in three rotations - not even for a moment.

Because only one-third of the people fired at the same time in three stages of fire, and the number of people who fired in each round of the regimental mountain army was the whole battalion. That is, the Tuanshan army sacrificed the ability to shoot sustainably in exchange for a larger killing area.

This is not cost-effective, in the era of hot weapons, continuous firepower output is obviously much stronger than stop-and-stop -- but the smoke generated after continuous shooting is the key to the victory of the immovable battalion!

It doesn't matter how many casualties there are in front - it's the moment that matters!

Seeing the opportunity, Mu shouted: "Don't move the camp, all go forward!" ”

Previously, both sides were shooting in place, but now there are only more than 2,000 people left in the camp and the camp has begun to advance!

The immovable battalion walked more than ten steps, and then there was a round of "pop pop" volleys, and the effect was several points stronger than before. Because as the distance approaches, the accuracy of the firebolt increases exponentially. Of course, this is not because the immovable battalion aims and shoots, and the so-called "aiming" is just like that in these years, but as the distance approaches, the projectile flight is more stable and it is easier to hit the target. If the distance is too far, it is not necessarily where the projectile will fly......

And the Swiss mercenaries are simply untenable, their place is already shrouded in gunsmoke, and there is no way to fight back. A Swiss officer yelled loudly, and the mercenaries began to retreat.

The original intention of the Swiss was only to leave the place where the smoke of gunfire was filled and reorganize the salvo, but how could the regimental mountain army give them a chance to form again?!

Gao Yuanliangbu on the left flank and Pan Batianbu on the right flank all beat the war drums, and the tension behind the formation also gave the order for the final blow!

Three bright red signal flares rose into the air, and the Qing troops who had fought with the Tuanshan Army knew that the red flares meant that the Tuanshan Army was about to attack...... (To be continued.) )
