At this time, Li Yu and the four staff officers were on the watchtower, using binoculars to observe the real battlefield situation.

"The time is still too rushed, the trench is not wide enough and not deep enough, it looks like it won't last long, and it will be broken through." Zhang Chengdong looked at it and said.

By this time, two naval guns had been moved to the back of the hilltop, and the other four guns had also been carried over. Two three-pounder guns and one six-pounder cannon were directly assigned to the infantry posts in the trenches, and the twelve-pounder guns and naval guns were placed on two grinding discs because of their long range, so that they could be rotated flexibly to deal with the two directions outside the Mao Soldier Battalion and the Youyang Native Soldier Battalion.

"At this time, it is estimated that Bai Shuai will use grenades," said Zhao Ren, an army artillery staff officer.

"There is a place that has broken through, you see, Bai Shuai's pro-military camp rushed up. Hey, that little girl in blue is Bai Shuai's daughter, this girl is really ruthless, a knife slashed on that Niu Lu's real face, and she chopped it directly. Infantry musket staff officer Wang Yihui said with a smile.

"Bai Shuai couldn't stop it, you see, he started to move the grenade box from behind. These Sichuan soldiers don't look thin and small, they are quite energetic, a box of twenty grenades has one hundred and forty catties, plus the box is estimated to be one hundred and sixty catties, one person can carry it and run fast. Cavalry staff officer Sun Dewei said.

Soon, there was a loud bang, grenades exploded in the trench, limbs and broken armor flew everywhere. Jiannu was directly bombed, and this was the first time that the Ming army used grenades on the battlefield.

One or two pieces of silver, Bai Zaixiang used the pain of the flesh, but it was really worth the money, the fifty or so Jiannu who had just rushed in couldn't stand it, and all ten grenades were blown up, and in the face of the shock wave of the offensive grenades, nothing armor was useless, and the people were all shocked to death, not killed by shrapnel.

The red-toothed soldiers leaning against their shields on the edge of the trench were also swept over by the air waves. I couldn't get up for a while, and the archers behind me were in a mess.

By the time the trench was blown up, the smoke had not yet cleared, and the wounded soldiers who had not died were still howling.

"Put the drawbridge down and kill me out." Ran Tianyi shouted.

With a bang, a drawbridge made of more than a dozen logs nailed with iron nails fell to the ground, Ran Tianyi wore the plate armor he bought from Li Jing, used a one-meter-and-five-long chopping knife/saber, and led five hundred personal soldiers who were also wearing plate armor to rush across the drawbridge and kill Jiannu outside the trench.

"Pay attention, the Youyang soldiers began to fight back. The pro-military battalion has already attacked. Li Yu said while looking at the telescope.

The Red Swing Tooth Horn soldiers were all knocked down by the air waves, and it was difficult for the eighty-pound heavy armor to get up by themselves, and they needed the help of others. Ran Tianyi rushed over and picked up the slash/saber to cut down the head of the Red Swing Tooth Soldier. Other pro-soldiers also used long knives to directly assassinate these elite soldiers who were usually difficult to deal with.

The archers quickly unleashed arrows in an attempt to rescue the elite soldiers. However, the armor-piercing arrows could not penetrate Li Jing's plate armor at a distance, and they bounced to the ground one after another, seeing that the armor was so powerful, the Youyang soldiers shouted in unison, solved the red swinging tooth soldiers, and directly entered the group of archers.

The archer wears two pieces of armor, which is actually similar to the two-grade armor of the Han and Wei dynasties, that is, two pieces of cowhide decorated with armor pieces in front of the back are linked with leather cords, hung directly on the shoulders, and then tied horizontally around the waist to share the weight. It can be protected from the shoulders to the knees. This rudimentary armor was lightweight, low-cost, and quick to produce, and was used to equip archers who needed to be agile and mobile.

These archers hurriedly threw their bows and arrows, pulled out their waist knives and slashed at Ran Tianyi and the others, facing the plate armor, their waist knives were useless at all, but the slashing/horse swords of the Youyang pro-military camp easily cut them into two from the waist horizontally, and the two pieces of armor had no protection on the sides of their bodies, and their arms could not block the long knives. The cowhide also has not enough strength laterally.

The pro-soldier battalion was like a tiger entering the wolves, cutting down the archers, and the other battalions also put down the drawbridge, rushing out, and all the troops on the front line of Jiannu collapsed. The tide receded like a tide. Sakhalian sighed as he looked at the retreating soldiers in front of him.

Ran Tianyi pursued and killed all the way, and after seeing the routed troops fleeing into the front army formation, he took the initiative to collect his troops and retreated to the camp behind the trench.

Bai Zaixiang was learning about the casualties of each battalion, and in the first half of the day, the Youyang native soldiers had lost 450 killed and 337 wounded. The casualties were heavy, and Jiannu also threw at least a thousand corpses behind. Seeing that it is getting dark, it is estimated that both sides will have to eat and rest for a while. Youyang soldiers still remembered Li Yu's words and dragged Jiannu's wounded soldiers away and sent them to the wounded soldiers camp in the prisoner camp.

The slave soldiers on Mao's side were subjected to intensive and accurate heavy arrow fire from the beginning of the charge, and the slave soldiers had no armor and were directly shot down by the arrows. There are white swing teeth in the back to press the formation, and retreating is a knife. Gradually approaching the camp of the Mao soldiers, it was impossible to dig a trench on the stone ground, so I had to build a breast wall with sacks.

The soldiers on Jiannu's side had a lot of firearms, and after the Mao soldiers had to shoot an arrow, they quickly squatted down and hid behind the breastwork to avoid being hit by muskets.

The Mao soldiers had no armor and were not ideal in the battle with Jiannu, and soon the ahas reached the outside of the breastwork, and the two sides began to fight, and when the elite white tooth soldiers in triple heavy armor also joined the hand-to-hand combat, the Mao soldiers could not resist.

"Send someone to inform Wang Shuai and ask him to retreat into our camp with Mao's soldiers," Li Yu said to the scout captain.

Jiannu followed the pursuit of Mao Bing to the foot of the high ground, and Nanao Town let go of a carriage for them to enter. Jiannu tried to follow in, and suddenly there were two loud bangs on the cars on both sides. The shotgun struck the head and covered the face. Suddenly, the man fell to the ground on his back.

A three-pounder gun on each side fired, and the shotgun was used directly at such a distance. The sound of muskets like popping beans rang out from the wagon. Jiannu fell more than fifty more.

Soon, thirty seconds or so, the two three-pounder guns began to roar again. Another shotgun sweep. The two guns fired at the same rate as the Kennu musketeers, and after two fires, the six-pounder opened fire, and the six-pounder fired at a rate of one shot per minute, using the same shotgun. The dense fires of shrapnel sent the slave soldiers back like a tidal wave.

The twelve-pounder guns and two heavy naval guns on the hill began to fire fiercely at the repulsing slave soldiers, and as they retreated, each cannon spherical bullet leaped forward and plowed a ditch, each ditch was a bloody alley.

Seeing that it was getting dark, Li Yu knew that today's attack was about to come to an end.

"Send someone to inform Bai Shuai that if Jiannu attacks at night tonight and can't hold it, they will all retreat to the watchtower of the camp, fight separately, and hold on until dawn, and it is estimated that the reinforcements from Fengji Fort will arrive.
