Two years ago, during the armistice negotiations in Yangzhou Prefecture, after the contest with Dorgon.

Wu Zheng has been thinking about how to maximize the advantages of the musketeers so that he can face the Tartar cavalry head-on when it is unfavorable.

Not to mention, I have thought too much, but I have not had any effective good ideas, but I have come up with many bad ideas.

Seizing this rare opportunity and conducting practical training for the soldiers of the Two Guards is Wu Zheng’s real intention. In fact, there have been no less than a hundred ferries by the river behind the defense line, so how can there be no possibility of a "fight with your back"?

In Wu Zheng's view, even if he is in a desperate situation, he will never learn from the tragic tyranny of a king. This is his personality.

Accompanied by continuous gunfire like fried beans, the arrogant iron cavalry kept falling off the horse. Although there were not many, it was enough to shock people.

The Iron Cavalry, who was inferior to swords and guns, was caught in a dozen in one volley, which accounted for 20% of the Iron Cavalry this feint attack.

This scene made the enemy a little panicked.

Could it be that the Northern Expedition Army has secret weapons?

Of course not!

In fact, the mystery of Wu Zheng’s tactics this time lies in the trench on the defense line.

When the soldiers digged a trench, they piled up a large amount of digging soil and stones on the side of the trench towards the enemy. They piled up as much as they dug out, and then left a foot-wide shooting warhead on the piled earth, just like battlements on the city wall.

In this way, the upper, middle and lower three levels are formed.

The soldiers were divided into three batches, standing in the trench, half-kneeling between the trench and the earth, and lying on the earth, but the shooting surface formed was almost at the same height.

In other words, almost three shooting positions are compressed to one and a half shooting positions, which indirectly causes twice the shooting density.

Of course, the density of bullets cannot effectively kill the Iron Cavalry.

However, the density of bullets can effectively kill and damage the war horses, to be precise, it is shooting the legs of the war horses.

This is also why soldiers have to risk the enemy's dense arrows to block them within fifty steps.

Arrows fifty steps away can penetrate solid wood boards with a thickness of two minutes, but cannot penetrate the earthwork several feet later.

Even the longbow shot by Yang cannot shoot, the soldiers of the Northern Expedition Army who are trenches and earth-shaking.

But the legs of the iron cavalry cannot be covered, which is also a variation in the effects of sickle hook guns and ground-walk swords when the Southern Song army fought against the Northern cavalry.

Muskets at least avoid the danger of getting soldiers to take the initiative to commit themselves under the hoofs of war horses.

The Iron Cavalry was slower, far less than the Rangers. After the second round of gunfire, no less than ten Iron Cavalry fell off the horse. So the remaining enemy cavalry drew an arc to the left and right about twenty steps before the earthwork and retreated.

The crossbowman behind the Iron Cavalry lost the protection of the Iron Cavalry and hurriedly retreated.

But the battle was not over and entered the second half.

The ranger, which originally protected the left and right wings of the Iron Cavalry, entered an effective combat area here.

Compared to the slow and heavy iron hooves, the ranger can jump over the trench, which means that the trench has no effect on the light chasm.

As the Iron Cavalry retreated, the soldiers of the Northern Expedition Army quickly retracted back to the trench, and began to load, allowing the two cavalry to easily cross the trench and break through the first line of defense.

After the enemy cavalry crossed, the soldiers of the Northern Expedition Army quickly turned and shot from behind the enemy cavalry.

The slight flaws of the cavalry were infinitely amplified at this time.

Everyone knows that no matter how powerful a cavalry is, when sprinting rapidly, they cannot quickly turn around. Especially groups of cavalry, they can only draw an arc to the left and right to adjust the direction, or slowly slow down to adjust the direction. Otherwise, they will collide with each other and will collapse without fighting.

But often in field battles, the defensive party attacked by the cavalry has no chance to seize this defect and is invisibly covered by the impact potential energy of the cavalry.

But Wu Zheng fought with preparation, deliberately grasped this defect, and then used earthwork and trenches to amplify this defect.

So, these two hundred light cavalry were only at the slaughter of others. First and second two lines of defense, after three rounds of volleys, there was no enemy still on the horse's back between the two lines of defense.

Been wiped out!

....

After this tentative feint.

The enemy did not launch another attack on that day.

The two sides are confronting each other within a distance that can be recognized by the naked eye.

But the next day, the ugliest thing about this battle happened.

The Tartars caught no less than a thousand people overnight in the city of Pizhou, strung them with ropes, and drove them toward the first line of defense.

The entire battlefield was filled with the wailing voices of the Han people.

It makes people feel sorry for it.

Now, there is nothing to do.

Wu Zheng had no choice but to order to retreat voluntarily, and in just half an hour, he lost two lines of defense.

In other words, if you retreat, the whole army will have to go to the river to swim.

"Your Majesty can't retreat again!" Lu Zhiyuan advised anxiously, "Once our army retreated across Zhihe, the Tatars rushed south, and the newly recovered Suqian was lost. Not to mention the life and death of the 800 soldiers guarding the city, just say that the Tatars tasted the sweetness this time, and then replayed the events of today with the people of Suqian. I am afraid that our army will not have to fight again in the future, so we might just retreat all the way back to Wusong."

Wu Zheng was really embarrassed. How could he not understand the principles stated by Lu Zhiyuan?

But the problem is that if this command is really out of your own mouth, you will have to live in the world's spits for the rest of your life.

It is not a matter of dying people in war, nor is it a matter of dying some civilians.

But if thousands of innocent people were shot to kill, I'm afraid only the demon could give such an order, and Wu Zheng believed that he could not do it!

"Transfer the order, retreat to the east coast!" Wu Zheng said in a deep voice with a stern face.

The Lu Region was anxious, "Prince... If he retreated to the east bank, the Tartars would drive the people across the river. How can we deal with it then?"

How to deal with it?

God knows!

Wu Zheng cursed dozens of generations of the Aixin family in his stomach.

....

Human nature is often not the most vicious, only the more vicious.

The Northern Expedition Army's third voluntary retreat was nowhere to retreat. All the soldiers boarded the boat and prepared to cross the river. Those who could not board the boat also climbed the boat side to prepare to swim across the river.

Logically speaking, this should be called the heart of the Tartars.

But when the Tatars saw the inevitable chaos that occurred when the Northern Expedition Army retreated, they rose from the side of their courage!

They charged!

Tactically speaking, this is undoubtedly the most profitable.

Any army will be in chaos when retreating, especially when boarding a boat and crossing the river.

There is almost no standardized action.

Wu Zheng often said this when he was sick.

But the problem is that there were thousands of innocent people in front of the Tartar cavalry.

What will happen if the people are strung by ropes and the Tatar cavalry suddenly charges?

You don't have to think about it and know...

This is a hell on earth!

Inhumanely slaughtered, trampled wildly, bloody, ugly, unsightly, outrageous bloody and ugly.
