In this era, there was no radio communication technology, and there were no so-called auxiliary telescopic devices and rapid transport.

The large-scale battle of hundreds of thousands of people actually had a lot of chances.

Neither Liu Zhaoji, the chief officer of the Guards, nor Zuo Liangyu, the commander of the Left Army, could understand the specific situation on the front line of the war anytime and anywhere, and they could only make arrangements according to the general situation.

And most of the armies are not yet able to participate, after all, no one is sure what will happen next.

Only the 1st Cavalry Battalion and the 1st Infantry Battalion of the Guards participated in the battle, while the Left Army also had only 2,000 iron cavalry to participate in the battle.

In fact, in this era, a real soul army with a claim to be hundreds of thousands of people is often an iron cavalry or other ace elite composed of thousands of people.

Now the left army has not collapsed, relying on these two thousand Ding iron cavalry and three thousand iron cavalry in Huaining City.

Once the iron cavalry composed of these Zuo Liangyu's slaves is completely annihilated by the Guards, Zuo Liangyu's army will be like a toothless tiger, of course, Zuo Liangyu will not wait until his trump card is completely annihilated before retreating.

Often, as long as the 2,000 iron cavalry outside the city did not repel the infantry battalion of the Guards, or was routed by the Guards outside the city, he would no longer defend Huaining City and immediately evacuate.

Hitting and running is the only foundation for Zuo Liangyu to survive and develop in this troubled world.

The Guards also relied on three infantry battalions and two cavalry battalions and two artillery battalions.

If Zuo Liangyu's iron cavalry really defeated the infantry battalions and artillery battalions of the Guards, then the First Corps of the Guards would undoubtedly suffer huge losses, and even lose the ability to fight together, and it would be difficult to break through Huaining City with cavalry alone.

What Liu Zhaoji is worried about now is whether the infantry battalion can hold back the attack of the 2,000 cavalry of the left army.

The performance of the 1st Infantry Battalion did not disappoint Liu Zhaoji, although under the pressure of the cavalry onslaught, there were indeed many people who showed signs of panic and confusion.

But fortunately, the A battalion is worthy of being a A battalion, and a large number of grassroots officers are veteran firearms soldiers of the border army, and even many of them have fought against heavy cavalry like the Tartars, so naturally they can also ensure that the basic formation is not chaotic.

In the past, the scholars of the Xiucai Battalion were able to take the examination all the way to the Xiucai Lifting Scholar on the way to the profession, coupled with such a long time of training and their own intelligence is not low, their ability to resist pressure is indeed extraordinary, and they can operate the flintlock pistol in accordance with the usual training in the face of cavalry.

Once the recruit fires his first shot, he no longer has time to think about whether he will die or not, but instead fully devotes himself to the interest in killing.

This is also the reason why violent games can be popular.

However, although the soldiers of the 1st Infantry Battalion of the 1st Guards Corps were able to calmly and calmly fire on the cavalry of the Left Army, the smoke from the pyrotechnic powder often caused great difficulties in the accuracy of the shooting after several rounds of firing.

In this case, both his own side and the cavalry of the left army shot like blind people.

The left army began to take advantage of the mobility of its cavalry to attack from the flanks, rode horses at a gallop, and quickly used smoke to cover the sides of the infantry battalion, and directly ignited the three-eyed guns to fire on both sides of the infantry battalion.

One of the Guards Commanders was shot directly, and the whole person fell.

Then, several more people fell, and if it weren't for the fact that Discipline and 6,000 men could not run away from other directions, the entire first battalion of infantry class A would have collapsed.

Of course, this kind of cavalry will strike from both sides, as veterans Zhou Yuji, Liu Fangliang, Liu Zhaoji and others have not taken it into consideration, even if Zhu Youzhen and a group of Wenchen can't think of it, they also want it.

At this time, Yang Tinglin had already ordered his own soldiers to blow the trumpet, and the meaning of the trumpet order was to change the twelve-style formation to the two-five type.

That is, when the cavalry of the left army galloped to the front of the formation, a battalion of 6,000 men immediately changed from a formation of 51 to 12 platoons divided into two wings, and one flank of 2,500,000 men changed direction and concentrated fire to strike at the flanks.

In addition, in order to resist the left's disrupted formation, the shield men will also move to the first row on the flank, while the spearmen who have been following the second row will immediately hang their flintlock pistols on their bodies and at the same time pierce their spears out of the shield.

The third platoon would also take bayonets to prepare the left army to dodge the spears and scatter the stabs.

This kind of pre-formation conversion has been trained many times, and after the first formation is not chaotic, the conversion is also very easy, according to the most basic formation, the first two targets are still responsible for frontal defense, while the third to seventh marks immediately turn right, and the fourth to eighth bids immediately turn left.

When the cavalry of the left army saw that the three-eyed guns and bows and arrows in their hands almost disrupted the infantry camp, their confidence increased greatly and they quickly interspersed, but when they saw dozens of spears and shields forming an iron wall in front of the formation, most of the cavalry of the left army who rushed to the front did not have time to turn and collided directly.

Several spears pierced into the body of the war horse, and in an instant, the blood flowed like an infusion, and the cavalry of the left army fell directly in.

He was stabbed on the spot by a row of bayonets and had holes all over his body.

However, the huge impact force made the shield soldiers at the front of the Guards unable to withstand it, although the choices were all brave, but many of them were shattered by their hearts and lungs, or directly smashed into flesh, or even directly smashed into the camp.

However, the Guards also had corresponding coping training during training, and immediately stepped back and resumed shooting.

The Guards in the rear had already begun to use flintlock pistols to shoot at the left army behind, and in addition to the left army in front causing some damage to the officers and men of the Guards, the cavalry of the left army in the rear was again killed and wounded countless times.

The left army was not the cavalry of the Qing army, of course, even the cavalry of the Qing army could not have a good collapse rate in this era, and after seeing that the attack from the flank was ineffective, they began to shift their direction, trying to kill the infantry battalion behind as fast as possible.

The cavalry of the left army tried to disrupt the formation before the second battalion of infantry armor in the rear had not yet changed its formation.

However, by this time, the second battalion of infantry class A had been quickly changed to a one-to-one style by order of the battalion commander, that is, a formation of 1,000 men in a horizontal row to increase the coverage of firepower, and inflict a large number of casualties before the left army rushed in.

The 1st Battalion of Infantry Battalion A also continued to turn to the 2nd Battalion of Infantry Battalion to attack the cavalry of the Left Army in an upward and downward manner.

It is equivalent to using the infantry's firepower advantage and numerical superiority to suppress the cavalry with a small number.

The cavalry of the left army also knew that they were in the predicament of being attacked by the enemy on their backs, and hurriedly withdrew.

If it weren't for the poor mobility of the infantry battalion, and the fact that the flintlock rifles were not as good as the breech-loading rifled guns, the infantry battalion could have completely annihilated the cavalry of the left army, not just repulsed.

At this time, Liu Zhaoji saw this and decisively ordered the 3rd Infantry Battalion and the 2nd Cavalry Battalion to immediately rush to the other exit of Huaining County, that is, the location of the Huaihe River, so as to avoid Zuo Liangyu from withdrawing immediately after knowing that his 2,000 iron cavalry had suffered a big loss.

At the same time, the other three battalions of infantry and artillery began to advance towards Huaining County step by step.
