The commander of the Thunderbolt cavalry company took the lead and rushed at full speed towards the new annex array, followed closely by thirty cavalrymen. The horses of the Thunderbolt Army are not easy to come by, and they are carefully cared for on weekdays, and the cavalry has a deep affection for the mounts, and it is not an exaggeration to say that they are comrades-in-arms. It's just that today is different, in order to make the horses rush faster, they even do not hesitate to whip their mounts fiercely, and even use spurs. At this moment, both the enemy and the enemy on the battlefield understand that it is undoubtedly a suicidal act to attack the phalanx of 1,000 infantry formed by a mere few dozen cavalry. What's more, behind the phalanx of infantry of the new annexed army is the river bank. There is no need to guess what will happen to the cavalry charging at high speed and rushing to the pebble beach below the river bank. Of course, the cavalry company commander and his subordinates of the Perak Army knew the consequences, but they did not look back, and their expressions were resolute.

In the face of the rapidly approaching Thunderbolt cavalry, the first to strike was the crossbowmen of the new annexed army. After two rounds of dense rain arrows, the cavalry of the Thunderbolts, although all clinging to their horses, lost nearly a third of their riders. In an exclamation, the remaining twenty-one horsemen rushed into the spear and shield array of the newly annexed army. The commander of the cavalry company of the Thunderbolt Army, who rushed to the front, was pierced by a spear with a horse. The cavalry that followed also fell under the spears, and after seven or eight horsemen fell to the ground, they rushed into the crossbowmen's formation in the rear. It's just that before dying, the cavalry company commander and his subordinates both pulled the grenades on their waists. As they heroically fell to the ground, grenades exploded one after another in the new annex array, blowing up its dense formation. The Thunderbolts' cavalry is equipped with five grenades as standard, which were partially used in the first two raids. According to the calculation of three grenades left by one person, the cavalry detonated a total of about fifty grenades in the new annex formation. The new annexes were killed and wounded by these grenades at least a hundred people.

At the same time as the commander of the cavalry company was charging into formation, taking advantage of the attention of the new annexed army, more than a dozen Thunderbolt cavalry rushed to the slope made of logs and dirt bags. They hurriedly dismounted, took their weapons, and galloped up the slope to the fort wall. At this time, the crossbowmen of the new annex army were stumbling from the grenades, and they had no time to pay attention to them. Li Laosi, who was lying on the ground, heard the sound of footsteps and was about to pull the improvised explosives bag, but found that the person who came was a comrade-in-arms, and he couldn't help but be overjoyed. The dozen or so Thunderbolts turned to defend, and then divided a few more people and hurried to the back gate of the fortress, letting in the other thirty Thunderbolt cavalry. Their mounts were led by two cavalrymen in the direction of Mianzhu's reinforcements. Standing on the fortress wall at this moment, I can already see the reinforcements coming from the direction of Mianzhu, and the distance is only three or four miles.

Yang Wen'an also learned the news that the reinforcements of the Perak Army were about to arrive, and at this moment he had crossed the river to personally command the frontline. Based on the smoke and dust rising in the distance and the slight shaking of the ground, he judged that the number of Thunderbolts approaching the battlefield was not large, and it was probably the forward force of a lightly armed forced march. Although these strikers who arrived first were elite, they were definitely tired due to the long-distance running, and the lack of heavy equipment made their combat effectiveness not too strong. Therefore, on the one hand, he ordered to reorganize his formation, and prepared to attack the slope and occupy the fortress in one go, and he saw that the defenders were unable to run out of ammunition; On the other hand, he sent his men around the rear to block the Thunderbolt reinforcements from entering the fort. Now that the rest of the Thunderbolt cavalry had entered the fort and the horses had been taken away from the battlefield, he no longer had to worry about being raided by the cavalry.

The 1,000 new annexed troops who crossed the river were killed and wounded, and only about 700 remained. Yang Wenan understood that due to the narrow attack surface, it would not take so many people to attack the fortress at all. So he left only 300 men to continue the siege of the fortress, and the reinforcements sent to block the Thunderbolts were 400 men, including 100 crossbowmen and 100 sword and shield men, and the 200 Iron Man. At that moment, they were half a mile behind the fort, and they set up a phalanx against the Thunderbolt reinforcements coming from the direction of Mianzhu. At the head of the phalanx were fifty sword and shield men, behind them were four columns of Iron Man troops, and crossbowmen were lined up behind Iron Man troops. At the back of the phalanx were fifty sword and shield men lined up in the direction of the fortress to prevent the soldiers in the fortress from rushing out. In fact, the Thunderbolts in the fortress were currently struggling to resist the new annexes attacking from the slope, and it was impossible for them to rush out and attack. To say that Yang Wen'an's command is very old, the 400 new annexes who have undertaken the task of blocking have just set up their formations, and the reinforcements of the Thunderbolt Army have arrived. The distance between the two sides is only 200 meters at the moment.

As Yang Wen'an guessed, the reinforcements who arrived at this time were 200 pioneers of Zhou Jianshen's brigade, led by a deputy battalion commander. Because of the forced march, they did not carry artillery, but only light weapons such as swords, shields, spears and grenades, but they were armed with eighty breech-loading muskets of the latest type. Due to the use of fixed copper-shelled bullets, this musket saves a lot of reloading time, and the rate of fire is only slightly worse than that of bows and arrows. Seeing that the fortress was in danger, the deputy battalion commander of the Perak Army, who led the vanguard, was anxious and immediately ordered to form a battle formation, preparing to break through the resistance and enter the fortress. Just as the deputy battalion commander of the Perak Army wants to fight a quick battle, the general who led the team to block the new annex army also wants to eat the current reinforcements in one bite, freeing up his hands to deal with the reinforcements behind, so that the Thunderbolt reinforcements will become a futile "fuel tactic".

Both sides have their own holds. Although the top brass of the Perak Army has repeatedly stressed that the enemy should not be underestimated, a series of victories still inevitably make all officers and men proud. The new annexed army is the Iron Man Army, Yang Dayuan's Iron Man Army has rarely met opponents in previous battles, and has won many victories in the confrontation with the Mongol Han army of Lizhou Wang before the surrender to Mongolia, and even in the confrontation with the Mongolian cavalry, it has never fallen behind - ordinary swords can't hurt the Iron Man Army at all, and feather arrows are even more impossible, only hammers, bones and heavy axes can only break armor. Coupled with the fact that the number of new annexes facing the current battle is twice that of the Thunderbolt Army, how can it be unreasonable? Therefore, the two sides invariably blew whistles and brass horns, ordering the array to move forward, intending to defeat each other in one fell swoop.

The deputy battalion commander of the Perak Army was proud, but not arrogant. When teaching the brigade to study, he had listened to Ouyang Xuan's lectures, and he also remembered the sentence "stubborn and stupid", and he was not overly aggressive. So when the distance between the two sides was about 100 meters, he ordered the advance to stop: the shieldmen were in the front line with fish scales, and the spearmen were on the left and right of the musketeers. Seeing that the Thunderbolt army stopped, the new annex general commanded thought that the other side was timid, so he ordered to speed forward, on the one hand, because the archers behind had not yet entered the firing range, and on the other hand, the iron man saber of the self-holding department was invulnerable, and could break into the Thunderbolt army's formation in one fell swoop.

His order hurt the fifty swordmen and shieldmen who rushed to the front, and after three rounds of fire, most of them died under the muskets and grenades, and the rest were pierced with spears and bloody holes. It's just that these sword and shield bearers are also qualified cannon fodder, and under their cover, the Iron Man Army successfully approached fifty meters in front of the Thunderbolt Army. The crossbowmen who followed them also came into range, and they bent their bows at a forty-five-degree angle into the sky, and the dense feathered arrows flew past the Iron Man Army and fell into the Thunderbolt formation, causing a cry of pain. Although the shields and rattan armor equipped by the Thunderbolt army blocked most of the bows and arrows, they could only cover important parts such as the torso and head, and it was inevitable that some people would be hit by arrows in their limbs.

The Thunderbolt muskets could only fire directly and could not return fire with projectiles at the archers of the new annexes, so they aimed their guns at the Iron Man Army coming from the front. Although Ouyang Xuan attached great importance to the research and development of muskets, and the technicians of the Thunderbolt Army continued to improve the muskets and black powder, the current power was not enough to penetrate the armor of the Iron Man Army at a distance of fifty meters. Therefore, after a round of gunshots, the Iron Man Army was unscathed, and still pressed towards the Thunderbolt Army with heavy steps unhurriedly, which made the Thunderbolt soldiers panic for a while. It is said that in front of the spears held by these fierce gods, the shields and rattan armor of the Thunderbolt soldiers are like paper, and Ren Rang will also panic in his heart.
