Li Yan asked the troops to camp in the south of the city, and lit a circle of bonfires at a hundred paces on the periphery to illuminate the surroundings. The 'Le' Wen and 'L' troops were divided into three groups and took turns to guard and rest.

The craftsmen in the battalion rushed to work overnight, using timber cut nearby to make improvised gun mounts. There are no other requirements for the gun carriage, that is, it must be strong, especially the base and lugs, which must be able to withstand the weight of the gun and the recoil of the gun. Fortunately, the craftsmen are all skilled hands from various workshops, and the tools are complete, and the gun carriage is made quickly and well.

There was no night attack by the Qing army, and the Manchurian and Mongolian lords were all doing nonsense in the city to vent their emotions, and the remaining Han soldiers and slaves who were trembling in their hearts dared to come out to carry out night attacks

There was nothing to do all night, and early the next morning, Li Yan asked half of the troops to line up. He had already observed that since the Qing army had not renovated the outer trenches, it was impossible to place artillery behind the low walls, and only a few Franky guns could be placed on the few reserved passages. And these artillery pieces were also damaged or withdrawn by the infantry before they left the camp.

The infantry stopped two hundred paces away, and then pushed out the captured Qing artillery from behind, which was padded to the rolling logs. It was too late to make axles and wheels on the fly, so it was possible to save some effort by putting the artillery and gun carriage on the rolling logs and pushing them forward.

The artillerymen were assigned to operate the operation, and the baggage soldiers also spent the night wrapping up many of the captured gunpowder in their respective quantities. Although it is wrapped in paper, it is much faster than scooping it in again and spoonful after spoon when it is launched.

Once the cannon was lowered to the leveled ground, the artillerymen began to adjust the angle and began to test fire. The sound of artillery firing soon intensified, but the results were not very large. Li Yan's artillerymen were not yet fully familiar with this kind of artillery, and the adjustment angle could only be adjusted with the size of a wooden block padded to the tail of the gun, which also made them very uncomfortable.

However, half an hour later, the outermost low wall in the south of the city was basically flattened by Li Yan's artillery with these captured artillery. The low wall of earth could not block the attack of solid bullets, and each projectile passed through a large gap, pushing the nearby Qing guards into the ditch behind.

Dorgon watched all this from the top of the city, and his face turned pale. He shouted: "Why don't you arrange the soldiers to stand on a three-foot-wide platform, how can you defend it?"

"These ditches were originally used to besiege the city, but now that we are inside, we don't have time to change them." He Luo will report.

Dorgon flew up with a kick that knocked his henchman to the ground. He's so angry, he's always been gentle and elegant, where can it be so intense.

"If you have time to kill people, set fires, and commit adultery in the city, you won't have time to change the layout of the city defenses, do you all want to die here, and you must have fun in time before you die," Dorgon gasped and roared.

He Luo would kneel on the ground and not say a word. Although he asked the Han army and the servants to hurry up and reform last night, the Han army was disheartened, and they just changed their way to deal with it. This was impossible to happen before, you know, these three trenches were also built by these Han soldiers and slaves, and it only took a day and a half. But now that the people are panicking, he doesn't dare to punish him heavily.

Dolgon roared: "Go and arrange the defenses, transfer more men, and kneel to the south to make Li Yan retreat."

When He Luo would hurriedly run down the city, Dolgon asked each banner to send 200 cavalry, go out of the city from the north gate, and go around Li Yan's back to attack and delay Li Yan's attack. What he had to do now was to hold Li Yan back, and wait for Azig and Duoduo to return with their troops, so that they could surround Li Yan and deal with this fierce enemy in one fell swoop.

And Li Yan's side did not move at all, and the artillery continued to aim at the second trench and began to shell. They were more than 260 paces from the second trench and were well within range of artillery fire.

After some time of adjustment, the artillery fire intensified again. With the passage of time, the artillerymen under Li Yan became familiar with the captured artillery. Moreover, the artillery of the Qing army was very well cast, and the sights were also very useful, so Li Yan's artillery was quite quick to get started.

In less than half an hour, most of the low walls in front of the second ditch in the south were also collapsed, and the losses of the Han army and the slaves were relatively large. At this time, the soldiers behind the third low wall began to retreat without orders, which made the old men in Manmeng anxious. If this happens, their authority will be lost. The Manchu soldiers began to execute their escaped slaves, and Dolgon beheaded two Han officers as a deterrent to the Han army.

Li Yan finally began to advance in the afternoon, and the troops reached the position of the first trench, and began to expand and guard on both sides. Although Li Yan looked at three directions, the artillery in each direction still made the Qing army dare not move. Then he pushed the captured artillery forward, ready to start a direct bombardment of the city walls.

At this time, the cannon at the head of the city finally began to sound. However, the land under the city was very soft by the trenches dug and destroyed by both sides, and the solid bullets basically could not bounce, so the casualties caused to Li Yan's troops were much smaller, which can almost be explained by accident.

Seeing that Li Yan's artillery was getting closer and closer to the city wall, everyone in the city began to panic. They knew that the Shenwei General Cannon could hit three miles, and it could already reach the city wall. And Li Yan's cannon is definitely no worse than their Shenwei General cannon. This Tongzhou City is not the city of Beijing, and if it can withstand the blow of cannonballs, the city wall will be collapsed sooner or later.

But let them attack Li Yan's army formation, and they were reluctant to suffer casualties among their men. Besides, Li Yan is only in the south, not even counting the lack of one of the three enclosures, you can leave if you want to, why fight to the death

The cavalry sent out was also bent on avoiding the battle, and did not dare to harass Li Yan's military formation, but went far to the rear, wanting to cut off Li Yan's grain route. However, all of Li Yan's food and ammunition were brought with them in the military formation, and they waited for a long time and could only return in vain.

In the evening, Li Yan's artillery really began to bombard the city wall with the ten Shenwei general cannons that captured the Qing army. However, this is not a real bombardment of the city walls, it is just a test firing and adjusting the angle. It was very difficult for these improvised gun mounts to adjust the angle and direction, so the artillerymen had to fix the angle of each gun before it was dark, and then they could directly and continuously bombard the city wall tomorrow.

Li Yan also asked the troops to move the camp before dark and protected the artillery in the camp.

"Inform all ministries that they must be vigilant tonight." Li Yan commanded: "Tonight is the only chance for the Qing army, and it is very likely that they will attack the camp." We must pay special attention to fire prevention, if there is a loss of gunpowder and grain and grass, we will die and have no place to be buried, and the officers must go to the front in batches to supervise the soldiers, and there must be no slackness, otherwise we will be severely punished."
