Early the next morning, after Li Yan's troops had eaten and drank ginger soup, they began to bombard the city wall of Tongzhou. Of course, in order to save ammunition, only the ten captured Shenwei General Cannons were used.

At the same time, the soldiers also set up thick bunkers around the gun emplacements. These cannons are not like their own cannons have gun carriages, they are easy to move and adjust the angle, but the adjustment of the light of these cannons took nearly two hours. Before the city wall was bombarded, these cannons could not be moved, so they were also more vulnerable to artillery fire from the Qing army, and of course defensive measures had to be prepared.

However, Li Yan had already instructed that if there was danger, these cannons could be given up and the safety of the gunners should be given priority. These artillery pieces were just a decoy for Li Yan, and if the Qing army sent troops to attack the artillery, then it would be able to kill and injure a large number of Qing soldiers. As for when the walls will be destroyed, no one knows, so we can't completely hope for the walls to fall. What's more, there is also the Qing army in the south that will rush back within a few days.

"Boom", "boom", "boom", the guns began to fire in turns, and a telescope passed in the middle of the gun group to observe the impact point of the projectile, so that the improvised gun carriage could be adjusted at any time. Although the improvised gun carriage is made strongly, it is made temporarily after all, and it is inevitable that there will be problems of instability. Early detection and early treatment are much better than wasting ammunition indiscriminately.

As for Li Yan's own artillery, except for a few four-and-a-half-inch cannons that were prepared to deal with the artillery on the city wall, the others were all prepared to deal with the offensive of the Qing army. His cavalry troops were cruising in the rear, lest his rear route be cut off by the Qing army.

He also had high hopes for these 5,000 cavalry, and the cavalry units that had dealt with the Qing army had shown their might before, crushing the seven or eight thousand cavalry of the Qing army in one fell swoop, and his own casualties were only more than 200 people. Of course, they couldn't tell the difference between the Han army and the Qing army of the Eight Banners, and they didn't know that those who wore thin armor or no armor were slaves, not soldiers.

If the Qing army felt that their cavalry was their strong point and went to trouble his cavalry troops, it would be just right to kill the prestige of the Qing army. And he kept here a force of two thousand men, including six three-inch guns, ready to go to reinforce the cavalry. Using artillery fire to kill and injure a large number of Qing troops is the best choice.

Li Yan himself rode around to check the movements of the Qing army, and the responsibility of commanding the whole army was entrusted to Li Mu. He found that the Qing army had no intention of attacking, except for a few cannons on the head of the city, which were firing one after another, the rest of the troops were still in place.

Since the Qing army had no desire to attack, and he also had no idea of attacking, the two sides only engaged in an artillery contest up and down the city of Tongzhou.

The artillery of the Qing army in the city was trying to fire projectiles at Li Yan's camp and those Shenwei General Cannons, but Li Yan's troops had already built sandbag bunkers, and it was not one, so those projectiles were blocked by sandbags, and the casualties caused to Li Yan's troops were almost negligible.

And Li Yan under the city is also bombarding the southeast corner of Tongzhou City with artillery. Although the ten cannons captured from the Qing army were basically on temporary artillery mounts, Li Yan's artillery skills were excellent, and the angle and direction of the cannons were adjusted yesterday. Therefore, at this time, every time the cannon is fired, the solid iron bullet can hit the area within a square circle.

With the repeated shelling, the masonry at the location of the bombarded city wall was shattered, and the loess inside was slowly exposed. The solid iron bullet then bombarded the compacted loess layer, and even the soil layer bonded with a binder such as glutinous rice egg white was sliding down.

Li Yan was very satisfied with the power of the Qing army's artillery, which was heavier than their own artillery, and more powerful than their three-inch guns. Although by noon, there was only a three-foot square piece of loess layer, Li Yan believed that as long as there was enough time, the southern wall of Tongzhou City would be completely collapsed. Before that, the Qing army should have a decision. For him, it is also time to make a decision whether to withdraw or continue to fight.

At this time, the Qing army did not make any moves, not because Dorgon did not want to fight, but because he simply did not have the ability to issue orders. Last night, he lost nearly four hundred taels of elite soldiers of the White Flag in vain, causing his headache and chest tightness to attack at the same time. This was his second seizure in two days, so he fell asleep after taking a lot of painkiller drink, but he never woke up.

The generals of the banners were nervously waiting for Dorgon to wake up, for they could not agree on anything. The other banners, including the Mongols, wanted to retreat, but the two white banners had to wait for Dorgon to wake up before making a decision. What's more, it's not a moment of danger, and Dorgon is only asleep, not in danger of his life. Otherwise, no matter how tough the two white flags are, they will not be able to resist the joint opposition of the other flags.

However, although the other flags agreed to retreat, the direction of retreat was different. Some people think that they should retreat to the Shanhaiguan in the east, and by the way, they should attack from both sides and take the Shanhaiguan Pass in their hands.

However, opponents believe that the Guanning army of Wu Sangui and others in front of them is blocked, and there is Li Yan's trailing pursuit behind, and they have no artillery to attack the city, which is the way to die. It would be more appropriate for them to return from the Great Wall Pass, after all, it was still the original Ming defense, and it would not cause them any trouble. And they were all light horses, there was no burden, and they thought that this was the best way to retreat.

Therefore, when the people of several parties get together, they quarrel with each other, and after they disperse, they all connect in tandem to find allies. Li Yan gave them too big a blow, just the banner Ding lost more than 3,000, this is the core force of their rule of the Qing Dynasty, which battle had such a big loss back then Duoduo only lost a dozen people, dozens of horses, was demoted by the emperor, fined silver, fined people, now the loss is so much, how to deal with it

It was only in the evening that Dorgon finally woke up. He listened to the rumbling artillery fire outside and asked, "What time is the hour, how is the battle going?"

Qi Chongge replied: "It's already unitary time. Li Yan was still bombarding the city wall, and there was no war. ”

"Youshi" Dolgon frowned and scolded: "Why don't you call me what it means that there is no war, you didn't send troops to attack Li Yan"

Qi Chongge said helplessly: "The flags have different opinions, so they didn't send troops. The prince drank too much medicinal wine, and the doctor said that the prince was weak, and it was best to let the prince rest for a while. ”

"Idiot" Dolgon scolded angrily: "I don't see when it is time to immediately summon all the banners to come here to discuss the matter."

Qi Chongge hadn't moved yet, and Suke Saha came in. Seeing that Dolgon had finally woken up, he immediately reported: "Regent, Li Yan has stopped attacking the city wall and has begun to attack the east. ”

"Attack east," Dorgon frowned, getting out of bed and walking barefoot. After a while, he suddenly stopped and asked, "How is the city wall?"

Sukh Saha replied: "Although a large part of the masonry has been knocked off the outside, the walls are still strong and show no signs of collapse. ”

Dorgon shook his head and frowned, "There is a problem, there must be a problem. Let's go, I'll see for myself. ”

"Regent, it's dangerous out there." Qi Chongge and Sukh Saha are both dissuaded.

But Dorgon did not hesitate at all, and ordered: "Come, put armor on this king"
