In this way, when Yu Xiaotian invited Dolgon to fight to the death, the Jiannu on the east bank of the canal had been completely defeated by them and completely lost their combat effectiveness.

Therefore, at this time, Yu Xiaotian also transferred part of the troops of the Second Brigade to the west bank side and strengthened it into the decisive battle.

This time, Yu Xiaotian dispatched troops, totaling more than 20,000 people, and a total of four brigades were put into the battlefield, of which three brigades were less than the number of units, and the number of artillery pieces was as high as 160, mostly 12-pounder howitzers, and a small number of six-pounder cannons, and a total of two battalions of cavalry, with a total of more than 2,000 people.

As for Dolgon's side, he took out all the capital this time, in addition to leaving part of the troops to guard the people who were coerced and the materials they looted, it can also be said that all the troops that can be invested are put into the battlefield, in the hope that this battle can defeat the family army and completely open the way to withdraw from the Guanwai.

After the scout reported the news of Jiannu, Yu Xiaotian slightly acquiesced about the time, this time his army arrived at the battlefield about half an hour ahead of the enemy army, so this time he seized another opportunity.

Within a few miles ahead, the scouts of the Yu family army had already formed a blockade of the frontal battlefield, and within a few miles, they had basically blocked the way for the Jiannu scouts to come to investigate the situation, so this provided him with a fairly good opportunity.

Yu Xiaotian's eyes rolled, revealing a treacherous smile, and he turned his head to Meng Fei who was following him and said, "I said that you are still stunned for what to do?" Are the sappers a little too idle? Why don't you find something for them to do? Don't you bury the gifts we prepared for Jiannu? What are you doing? ”

Meng Fei patted the fine steel helmet on his head after hearing this, and agreed with a look of chagrin: "Look at my head, I didn't know what to think about just now!" Yes, sir! Ha ha! Let's arrange it! ”

After saying that, the guy saluted, turned around and ran away with a smoke, and began to arrange.

However, in a few minutes, a group of unarmored Yu family soldiers flew out of the large formation from several places, and carried a lot of things, and after running to a distance of more than 100 meters in front of the formation, they immediately began to slash like a group of marmots, with the pickaxes and shovels they carried.

They moved very quickly, and soon dug a large deep pit in front of the army, and put some tight things wrapped in oilcloth into the pit, and then poured a lot of stones on it, broken porcelain pieces, broken iron pieces, etc.,

Of course, there are also people who use more professional things, which are some iron round cast iron cans, which can be put directly into the deep pit, and then they immediately hang a rope on these iron cans, and after checking that they are correct, they pull out a pin on the iron cans, quickly seal the pit with soil, bury these things, and sweep the surface with a broom, so that they cannot see that something has been buried here from a distance.

Then the sappers put down the ropes and rushed back to the big formation, and a special person was in charge of watching some ropes.

Yu Xiaotian looked at the busy work of these sappers, and a wicked smile appeared on the corner of his mouth, these things were some other gifts he prepared for Jiannu, to put it bluntly, they were land mines.

Some of the better are specially cast iron mines by the arsenal, and because of the limited quantity, some explosive packs are simply used, since the fire cap was successfully developed, the application of mines has gradually matured, although the pull fuse has not been successfully trial-made, but the use of mechanical fuse has been tested first.

These mines are equipped with a simple mechanical firing fuse, which replaces the ignition method of laying a long fuse to ignite the mine, which makes the mine really have actual combat capability.

The firing fuse, in fact, is a simplified spring and hammer, the mine is equipped with a fire cap, usually stored, do not install the fire cap, use the pin as a safe, when using, remove the wax seal, pull the machine bracket, hang the fire rope, and then pull the pin, you can complete the firing preparation.

Once used, you only need to pull the fire rope hard, and the nose will hit the fire cap under the action of the spring, and the fire cap will ignite, and the mine can be detonated.

So it was not until this time that things like mines were used by Yu Xiaotian as a standard weapon and equipped for the use of sappers.

Today, he rushed here one step ahead of schedule, of course, he couldn't wait for the Jiannu army to come, prepare a little gadgets for them in advance, and it would be good to surprise them at that time, and in addition, he just happened to test the actual combat effect of this mine.

Not long after the sappers had just completed the task of laying mines, a very wide black line appeared on the horizon in the distance, and through the eyepiece of the telescope, it could be seen that it was a black line composed of people and horses, and countless Jiannu were rolling in from a distance, like a swarm of super-large marching ants, spreading over the land and slowly heading towards the battlefield.

At first glance, it is really extraordinary, there is a menacing posture, in the Jiannu army, this time is also the banner is waving, the armor is bright, under the light of the morning sun, the sword and gun reflect the cold light.

But Yu Xiaotian sneered, after this period of time, he and Jiannu have repeatedly clashed, what is the strength of these Jiannu army, he has already known the bottom of his heart, although it seems that the terrain of this place is open, but because the east is a canal, and the west is another small river, such terrain seems to be flat, but for the army decisive battle, it is not necessarily conducive to the side with more troops.

Jiannu is known for its cavalry, and it seems that it is very conducive to their cavalry to attack here, but the width of the battlefield is so large, even if Jiannu has more troops, it can only be put into the battlefield in batches.

And the Yu family army does not seem to have as many troops as Jiannu, but it can be deployed on this side, and there is no need to worry about the left and right wings, and it will be attacked by the Jiannu cavalry.

What's more, the infantry phalanx of the Yu family army has a very strong defensive power, and nearly twenty infantry phalanxes are formed in battalion units, firmly controlling the battlefield, even if there are no temporary construction of defense facilities such as the breastwork here, but with the infantry phalanx of the Yu family army itself, it is still the nemesis of the cavalry.

Coupled with the firepower output ability of the Yu family army, Dolgon dared to come to the battle in this battle, and the Jiannu side itself was already at a disadvantage, so Yu Xiaotian was not afraid of Dolgon's Xingshi coming, but he was afraid that he would not dare to come, if Dolgon now broke his wrist and gave up the hundreds of thousands of Ming people and countless goods they had taken captive, he suddenly turned around and chose the road, bypassing Tianjin Wei, and directly inserting into the west of the Beijing Division, and going west to highlight the pass.

Then he Yu Xiaotian really only had dry eyes, and he was completely powerless to prevent the Jiannu army from escaping.

But now, when he saw that the Jiannu army had been killed from afar, his heart was completely in his stomach, and he immediately ordered: "Give the order to the artillerymen, today is the day of the decisive battle, so that they can ignore the consumption of ammunition and artillery, and let go of my hand to fight me!" Don't settle too much, as long as Jiannu enters the farthest range of our artillery, you can fire, I want Jiannu to tremble in the roar of our cannon from beginning to end! ”

When the artillery officers heard this, they were all overjoyed, and this time they came with double ammunition, in addition to the artillery front car stuffed with ammunition, the baggage battalion also carried an extra reserve ammunition for them, just to have a good time today.

Now that Yu Xiaotian has issued such an order, it is equivalent to letting them fight casually, as long as they reach the other party, there is no need to save ammunition, which is another form of mercy for them, so these officers are like chicken blood, and they suddenly crooked their mouths.

You must know that being an artillery soldier is a very face-saving thing for the family army, and being able to be an artillery officer is a more face-saving thing, because artillery is a technical branch, and it has higher requirements for su zhì, and it also has higher requirements for physical fitness, whether it is an officer or a soldier, it is a selected one.

And the artillery is generally in a relatively safe position during the war, and it is also a very cool thing to shoot artillery, although it is very hard, but this cannon fires, compared to the infantry shooting with muskets, it is much more enjoyable, and it sounds happy.

Because of the high consumption of artillery, under normal circumstances, when fighting on the battlefield, it will not be open for them to fight casually, and it is often at the most important time that they are allowed to fire, which makes many artillerymen feel unpleasant, and sometimes the low-intensity combat, and even their artillery only has the share of dry staring, just put two guns at will, and the infantry rushes and it is over, so the artillerymen rarely have the opportunity to get such an opportunity to open up and fight casually.

But today Yu Xiaotian issued an order for unlimited artillery bombardment, which allowed these artillerymen to have a full time with artillery, and it was no wonder that these guys were unhappy, and they immediately began to prepare one by one, and the muzzles of one cannon began to slowly raise under their operation.

Although the direct firing distance of the twelve-pounder gun is not far, at most about 400 meters, if the muzzle elevation angle is raised, it can fire solid shells at a distance of 1,200 meters at most, and can ensure that it can effectively hit a target the size of a house.

Therefore, after hearing the order, the artillery immediately adjusted the artillery to the maximum effective range, that is, a distance of 1,200 meters, aimed at the direction from which the Jiannu army came, and prepared for artillery bombardment.

At this time, Dolgon and Du Du and other slave chieftains led tens of thousands of troops, and they had already entered the battlefield, and stopped three miles away, these guys were not stupid, they knew that the artillery of the Yu family army could hit far and accurately, and they could almost hit about three miles, so they did not dare to get any closer, but stopped three miles away.
