Before dark, the Tatar Chinese army and the Tatar vanguard army converged, and in the big tent, Su Jianghai personally told the two charges of the daytime vanguard army to Buyan Chechen Khan and the tribal leaders of the Chinese army.

With Su Jianghai's story, many leaders in the big tent frowned, according to what Su Jianghai said, the enemy in the Bohai Sea seemed to be really very strong, and more than 10,000 people were killed and wounded in just two charges, which was a situation they had never encountered before.

After finishing speaking, everyone in the big tent was discussing whether to continue to attack Bohaisuo, some said to continue the attack, some said to attack in another place, and some were silent.

In the end, it was up to Buyan Chechen Khan to make a decision to attack the Bohai Institute tomorrow, and if it failed and proved that the enemy in the Bohai Institute was really very strong, he would break through the pass in another place, and it was best to break through the Bohai Institute with one blow to avenge the warriors who died during the day.

In his heart, Buyan Chechen Khan thought that the defenders in the Bohai Sea should be a rare elite of the enemy, and the destruction of this elite would also be a good thing for the Tatar army to occupy the area north of the Yellow River in the land of China, and it would be contacted sooner or later anyway.

As for the enemy's reinforcements, the land of China is in the midst of civil strife, and I am afraid that this Bohai Sea will not receive many reinforcements, and a small number of reinforcements is almost negligible for a 150,000 Tatar army.

At midnight, the two musket regiments that came out from the direction of Beiping City finally arrived at the Bohai Institute and quietly entered the city, even if there were Tatars staring at the Bohai Institute outside the pass, they did not know that the Bohai Institute had a support army, even if they knew that the reinforcements were coming, they were not worried, the number of this support army was too small, less than 3,000 people.

The two musket regiments came overnight to make Zhang Xinquan feel a lot more relieved, only 50,000 or 60,000 Tatar cavalry during the day, and in the evening there were more Tatars coming, and the two Tatars together could have more than 100,000, even the reinforcements of these two musket regiments Zhang Xinquan also thought that it was not enough, and after the arrival of enemy reinforcements in the evening, Zhang Xinquan sent a signal corps to the headquarters to ask for more reinforcements.

At this time, Wang Shengrong led a new batch of reinforcements on the way, this batch of reinforcements is the 25th Division of the People's Army, one of the troops stationed in Beipingcheng, the division commander Peng Zhi, the 25th Division, except for the heavy artillery regiment, the other five regiments have come, because of the inconvenience of rushing at night, they will arrive tomorrow morning.

Wang Shengrong did not think of transferring troops from other areas of the Great Wall to support the Bohai Institute, mainly because he was worried that the Tatars would not be able to attack the Bohai Institute for a long time, and they would turn to attack other places, the Tatars were all cavalry, and the People's Army could not keep up with the speed of the Tatar cavalry.

When dawn came, the People's Army and the Tatars inside and outside the Guanwai had eaten enough to replenish their energy and began to prepare for battle.

This time not all the Tatars were on horseback, at least 30,000 Tatars were on foot, their weapons were mainly sabers, and the thousands of Tatars at the front were also equipped with shields, and the main task of these infantry was to rush up the city wall through ladders, and rows of powerful Tatars carried long ladders.

The Tatar ladder is the simplest kind, that is, a long ladder, not a tall ladder cart or a siege vehicle of the People's Army, and the number of Tatar craftsmen is small, making it very difficult for them to make more complex engineering equipment.

Before the battle, Buyan Chechen Khan devised a simple siege plan.

The maximum distance of the KPA can even reach 2,000 meters, but after 1,000 meters, the damage caused by those solid shells to the Tatars is relatively small, and the damage caused by the shells that can explode at a distance of 1,000 meters increases the damage to the Tatars, until within 700 meters of the city wall, the KPA's muskets bring great damage to the Tatars.

According to the combat experience of the vanguard army charging twice, Buyan Chechen Khan formulated a siege plan, the army first advanced to a thousand meters away, and then the cavalry and infantry launched a charge against the Bohai Sea together, and when they rushed to a close distance from the city wall, the cavalry shot arrows at the enemy on the city wall in batches to suppress the enemy on the city wall.

Shoot slower because they have a limited number of arrows and a limited number of sustained shots.

When the infantry rushes up, they can set up a ladder to start the siege, and when the infantry is attacking the city, the cavalry can stop shooting arrows to prevent accidental injury to the besieging infantry.

After drawing up the battle plan, under the orders of Buyan Chechen Khan, the Tatar army of 150,000 horses slowly advanced in the direction of the Bohai Sea.

The scouts quickly reported the movements of the Tatars to Zhang Xinquan, the first two Tatars were riding horses to the Bohai Sea, this time they were advancing unhurriedly, which made Zhang Xinquan a little confused, but Zhang Xinquan's heart was not much worried, and the three thousand four hundred musketeers on the city wall were Zhang Xinquan's confidence.

At 1,500 meters, the heavy Franc cannon of the People's Army began to wield its might, with the density of the Tatar queue, every solid shell smashed over would bring casualties to the Tatars, and if you were lucky, you would only break the Tatars' arms or legs, and if you were lucky, a solid shell would directly penetrate the bodies of three or four Tatars in a row, and the Tatars who were penetrated through the body would naturally be dead.

However, there were too many Tatars, only 150,000, and the solid shells fired by the KPA were too few, and the casualties brought to the Tatars were very few, which did not have much impact on the advance of the Tatars at all.

Forward, forward, when the Tatars were only a kilometer away from the Bohai Sea, the medium howitzers began to wield, and one grenade after another smashed into the Tatar array and exploded, causing the Tatars to increase the number of casualties a little, but it still did not affect the Tatars' advance.

It was the first time that Buyan Chechen Khan saw a cannonball that could explode, and he was curious, and he must take a good look at this kind of artillery and shells captured by the capture of the Bohai Sea.

The KPA also had too few howitzers, and the rate of fire of the howitzers was so slow that Buyan Chechen Khan lost the courage to advance, and it was not until he was still more than 700 meters away from the city wall that Buyan Chechen Khan stopped and gave the order to let the cavalry charge.

"Ulla!"

Tens of thousands of cavalry galloped forward, and behind the tens of thousands of cavalry, 30,000 infantry also strode forward, and just as the Tatars entered the range of the People's Army musketeers, the first row of more than 1,100 musketeers fired lead bullets representing death at the Tatars.

In the blink of an eye, more than 1,100 buckshot bullets passed through a space of six or seven hundred meters and collided head-on with the Tatar cavalry, and the next moment, the Tatar cavalry rushing to the forefront either fell from their horses or fell from their horses.

Seeing that Buyan Chechen Khan was shocked, he was glad that he did not rush forward with people in person.
