The Western Wei State bordered the Manchu Qing Dynasty, except for the grasslands in the north, mainly in Hedong and Zhongzhou.

There were no cities on the grassland, no herdsmen in the Western Wei Dynasty, and no subservient tribes, so they could not occupy the grassland for the time being.

There is not to the Central Plains, the Wei cavalry passed, the Mongols on the steppe dodged, and the Wei army could not get supplies, as soon as the cavalry retreated, the Mongols came back to graze, so in the original way, they could not occupy the steppe at all.

Therefore, the direction of the Wei army's main attack was not the Hetao Plain in the north.

In Zhongzhou, Luoyang is indeed a good direction of attack, with strong political significance, and at the same time, it can make the territory of the Western Wei Dynasty more closely connected.

It's just that the Wei army attacked Zhongzhou, and for the Manchus, there was not too much sense of urgency.

Even if Luoyang was besieged, Beijing still did not perceive a huge threat, so the Wei army sent only 50,000 soldiers and horses, led by Jin Shenghuan, to contain the Qing army in Henan.

The land east of the river is just between Xi'an and Beijing, and the Wei army occupies this place, so it can directly threaten Beijing, take Hedong, and then take Henan is a matter of ease.

Militarily speaking, attacking Hedong would allow the Wei army to take the initiative in the struggle for Beijing, and economically speaking, Hedong was a major tax collector for the Manchus, and taking Hedong would weaken the Manchus by at least three to four percent.

Therefore, in this eastern crusade, the Wei army of 100,000 troops attacked Hedong, and only used 50,000 horses to contain Henan.

At this time, after the second batch of Wei troops crossed the Yellow River, the Wei army in Hedong was close to 50,000 people, and the stretching military tents were almost covered inside and outside Pujin Pass, and all kinds of materials were piled up, which seemed a little crowded and messy.

The 50,000 Wei troops were blocked by Azig in Puzhou, and if they did not break through the defense line of the Qing army, the soldiers and horses on the west bank would not be able to pass, and the Wei army would occupy the east of the river in every way.

After the night attack two days ago, the Qing army was no longer fighting, and more than 40,000 troops hid behind the defense line, desperately reinforcing the defense line.

In the early morning of that day, Gao Yihuan and his generals climbed the hillside to observe the Qing army's defense line in order to formulate a perfect trench attack strategy.

At this time, the scene on both sides of the river has completely changed, and the trees that block the shooting boundary have all been cut down and disappeared, impacting the fertile fields on the plain, all of which have become ravines and built earthen walls.

The outermost part of the Qing army's front is a series of oblique stabbed wooden stakes, antlers to resist horses, and then there is a deep trench about one zhang wide and deep, which is also inserted with sharpened wooden stakes, and the excavated soil is piled up to a high earthen wall, and there is a female wall to the chest on the earthen wall, which is the same as the earthen wall of the Wei army, all of which are in the shape of "concave and convex", and the convex part is like the enemy platform of the city wall.

Gao Yihuan used a clairvoyant mirror to scan the first wall of the Qing army, on which flags were everywhere, and at intervals, there was also an artillery, and the Qing soldiers with hats were patrolling it.

Behind the first wall, there were several trenches connected to the second wall, and between the two walls, there were also stilted stakes, horses, antlers, and moats, and unlike the first wall, behind the second wall, there were several huge mounds of earth, behind which were hidden stone throwers.

The Wei army's mortar artillery had a long range, and it could also reach the front of the first line of front at the end, while the Qing army could only place the stone thrower in the second line of defense and cover it with a mound of earth to avoid being destroyed by direct fire from the Hongyi cannons.

The catapult is the same as the mortar cannon, the trajectory is parabola, too close to hit, too far to hit, and the area in front of the first front to reject the horse piles and antlers is the area with the most concentration of attackers, so it is necessary to put a little back and bombard there in order to cause more damage.

The third line of defense is basically the same as the second line of defense, and the three lines of defense of the Qing army extend from the plain to the slopes on both sides, and each has an earthen fort at the top of the slope.

In the middle of the three lines of defense is the water, the Qing army is connected by pontoon bridges to facilitate the rapid deployment of troops, and at the same time, on both sides of the pontoon bridge, there is a section of earthen walls, on which a lot of artillery is arranged, used to control the water surface.

Azig now learned and sold, and built a solid defensive line, and the Wei army had to wade through three lines of defense if it wanted to break through.

Gao Yihuan looked at the unrecognizable wilderness, the flags of the Qing army were flying, put down the clairvoyant mirror, and scolded in his heart, "Turtle Sun is really capable, I'm afraid it will be difficult for the lonely king to step down this time." ”

Huang Bingzhong said, "The minister estimates that Azig has copied all our things, such as sharp wood, thistle, antlers, rejection of horses, and earth-shattering thunder, and maybe add some of their own things!" ”

Zhao Daxian looked at the Qing army's defense line and said, "This Azig is really shameless. ”

Most of the generals of the Wei army looked solemn, but there were also a few who were addicted to war, showing eager to try.

At this time, between the Wei army front and the Qing army front, nearly 10,000 Wei troops were sweating like rain, digging trenches to push the front forward.

On the hillside, the Qing army's Hongyi cannon roared and shot at the Wei army who were working on civil engineering, and the shells splashed clouds of dust, but they did not hurt the Wei soldiers.

The Wei soldiers dug the trenches and advanced, the soldiers stood in the trenches, and the Hongyi cannon was not high, and the probability of wanting to smash into the trench was very small.

The Qing army fired a few shots, but it had no effect, and he felt bored, so the artillery stopped shelling, and the leading officer turned around to report to Azig.

Previously, Gao Yihuan said that many generals did not understand how to dig trenches.

At this time, he directly raised his horsewhip and pointed at the Qing army's front, and said: "If the army attacks directly, it will first be artillery, and secondly, it will be blocked by antlers, horses, and thistles, and the soldiers will be exposed, and they will inevitably be bombarded by Tartars' firearms, bows and arrows, and earth-shattering thunder. When they get close to the earthen wall, the soldiers will not have strong fire support, and they will be suppressed by the Tartars who occupy a favorable position, especially the stone throwers behind the second front of the Tartars, which will definitely throw thunder. If they cannot be suppressed during the attack, our troops will surely suffer heavy casualties. ”

"So the king thought of digging a trench, and kept digging at the foot of the Qing army's defense line to avoid exposing the soldiers to reduce casualties!" Li Ding National Road.

Gao Yihuan nodded, "More than that, we have to pull the mortar cannon over, build a wall under their feet and shoot at each other, to see who has more firearms and whose firearms are powerful." ”

As he spoke, Gao Yihuan raised his hand, pointed to the Qing army's front, and ordered: "Bingzhong, when the trench is dug to a distance of two hundred steps from the Qing army, dig a vertical trench, connect several trenches, and build a wall, and then the mortar artillery will be placed here to bombard the first line of defense of the Qing army." After the wall is built, continue to dig forward, fifty paces and thirty paces, and dig a trench again. ”

"No!" Huang Bingzhong immediately clenched his fists.

Gao Yihuan reminded again: "When digging trenches, it doesn't matter if the Qing army's artillery harasses it, the key is to prevent the opposing horse army from rushing out." Therefore, the artillery should be well covered, and when digging, it is better to build a horse wall every time it advances. ”

"King, in this case, the amount of work is not small!" Zhao Daxian said.

Gao Yihuan said with a straight face: "Don't be afraid of trouble, tens of thousands of troops are here again, just a day or two more work." ”

"No!" The congregation will salute again.

Gao Yihuan immediately waved his hand, "Okay, let's do it!" After speaking, Gao Yihuan turned his head to look at Gao Yicheng, "Before attacking, King Gu wants to see the movements of Luoyang, Xuzhou, Huai'an, and Beijing!" Xuan Yiwei will collect the news as soon as possible! ”
