The city wall first appeared in the primitive society, its predecessor was the fence and wall that people used to prevent the infestation of wild beasts, with the development of history, people found that the high point of the wall can not only prevent wild beasts but also prevent the invasion of hostile tribes, so the wall is higher and higher, the thicker and thicker the brick, and there are ancillary facilities such as female walls, arrow battlements, corner towers, etc., and the development to this extent can no longer be called the wall, therefore, people call it the city wall.

The city wall is the main means of defense during the cold weapon war, and the siege war is also the most common battle during the cold weapon war, the besieging side will generally persuade the defender to surrender first, and the soldiers who can surrender without a fight are naturally the best, usually as long as the two sides do not have a deep hatred, this persuasion is an essential link.

Daming just wanted Annan to be honest and obedient, and there was no deep hatred between the two sides, so before attacking the city, Lu Xiangsheng wrote a letter of persuasion and sent people into the city.

Zheng Jie received the letter of persuasion to surrender and tore it to pieces, he was a chaotic minister and thief, how could he surrender, after the Ming army entered the city, he would definitely help Li Shenzong to reinstate, and even if the Ming army did not kill him, Li Shenzong would also kill him, so if he wanted to open the city and surrender, it was really no door.

If you don't surrender, then you can only fight, Lu Xiangsheng waited for a long time and saw that there was no reaction in the city, so he immediately ordered the 50,000 elite cavalry of the Tianxiong Army and the Guanning Army to cut down trees and make siege equipment, while the infantry was deployed five miles outside the city, preparing artillery to bombard the city, and first flattened the arrow stacks on the city wall.

Annan also has artillery at this time, this Lu Xiangsheng knows, for the sake of insurance, he did not let the Tianxiong army and the Guanning army start to bombard the city at the same time, but personally led the Tianxiong army to test the range of the artillery in the city first.

Since it is a temptation, it is naturally tested with the longest-range artillery, and the farthest range of the Ming army is the 620-type field howitzer, with a range of almost three miles, Lu Xiangsheng gave an order, and 500 artillery men pushed 50 620-type field howitzers in a row, slowly approaching the city wall.

The commander of the artillery slowly followed the artillery, and at the same time observed the reference objects on the city wall with a telescope, and when he got closer, he almost reached the effective range of three miles......

At this time, there was a sudden roar on the city wall, more than 30 shells flew out from the city wall, and smashed into the Ming artillery that was marching, three miles away, the artillery in the city could shoot three miles away, although the accuracy was not good, there was still a team of Ming soldiers was smashed, and several Ming soldiers were suddenly blurred in flesh and blood!

It's the Dutchman's cannon! Lu Xiangsheng's face was pale, now the only cannon that can compare the range with the Ming artillery is the Dutchman's cannon, the Ming army has captured so many artillery pieces of the Dutch Far East Fleet, naturally they are not familiar with their artillery performance, the Dutch cannon is divided into two kinds, the one with a shorter range has an effective firing range of about two miles, and one with a longer firing range has an effective firing range of about three miles.

The Annanites must have used the kind of cannon that the Dutch had a shorter range, and with the help of the height of the city wall, it happened to have a similar range as the Ming 620 field howitzer!

What to do, Lu Xiangsheng thought quickly, but, after thinking for a while, he really couldn't think of any good way, at this time, the enemy troops on the city wall began to fire a round of shells, and several Ming artillery were unfortunately hit.

There is no way, then there is only desperate, Lu Xiangsheng gritted his teeth, and ordered loudly: "Order, the second artillery battalion and the third artillery battalion each launch fifty 620 howitzers, lined up on the left and right of the first artillery battalion, and all the one hundred and fifty cannons are aimed at the artillery positions in the city, and they will keep bombarding me with flowering shells." “

The herald immediately galloped away, and soon, another hundred 620 howitzers were pushed out of the Ming army's formation, slowly advancing to the left and right, and at this time, the 50 howitzers that came forward first had already set up their brackets and were ready to load the shells.

Fortunately, the Dutch only provided solid ammunition to the Annan army, and the artillery control technology of the Annan army was not very good, and the accuracy was extremely poor, but in a round of thirty or forty shells, there were always one or two rounds that could hit the artillery of the Ming army, and for a time, the artillery of the Ming army suffered continuous casualties.

Soon, the first fifty guns of the Ming army have been loaded, and the commander of the artillery used the scale on the telescope to roughly estimate the position of the artillery on the city wall, and reported a series of parameters, so that the artillery adjusted the gun position, and after a while, the various artillery positions raised the adjusted order flag, and the commander immediately shouted: "Release." “

"Boom, boom, boom" fifty flowering shells flew towards the city wall with an arc, and smoke immediately rose from several places on the city wall and hit!

In this way, the Ming army and the Annan army began to bombard, the Annan people were also a famous fighting nation in later generations, although the smoke on the city wall continued, but the roar of the artillery has not stopped, they seemed not afraid of death, knowing that there would be shells falling from their heads, or artillery constantly stepped forward to push away the corpses of colleagues and continued to fire.

The casualties of the artillery on the side of the Ming army are also getting bigger and bigger, and even some of the artillery has been smashed and scattered, and it can no longer be opened, Lu Xiangsheng frowned slightly, and ordered loudly: "Order, the Guanning army will hold on to the spot and not attack the city, and Cao Wenzhao will send two hundred 620 howitzers to the east of the city to support." “

An hour has passed, the Ming army and the Annan army are still bombarding, I don't know if the Annan army in the city has casualties, the artillery casualties on the Ming army's side are almost thousands, Lu Xiangsheng didn't say anything, just stood in front of the infantry formation, and looked at it coldly, the so-called Ci is not in charge of the troops, and casualties will inevitably be lost in battle, so casualties are just a small scene.

At this time, the artillery of the Guanning Army pushed two hundred 620 howitzers to appear on the left side of the main array, Lu Xiangsheng glanced at it, and immediately ordered: "Order the remaining 100 620 howitzers of the Tianxiong Army and the 200 620 howitzers of the Guanning Army to all be pushed to the front, and the artillery of the first battalion, the second battalion and the third battalion are ten steps apart, lined up in two rows, and also use flowering shells to aim at the artillery position in the city, and give me non-stop bombardment." “

Three hundred 620 howitzers were quickly pushed to the front of the battle, and the shells of the Ming army suddenly smashed into the city wall like rain, but the Annan army on the city wall was still firing back, and there were more and more shells, it seemed that they were also mobilizing artillery from other directions to come over and bombard the Ming army.

This artillery battle lasted for two days, the Ming army ran out of flowering shells, switched to scattered bullets, and when the scattered bombs ran out, they switched to solid bullets, and kept bombarding the city wall, and finally smashed more than 100 artillery pieces of the Annan army into dumb fire.

I don't know what the casualties of the Annan army in the city were, at this time the artillery of the Ming army had suffered nearly 10,000 casualties, that is to say, the artillery of the Tianxiong army was almost completely killed and wounded, and now the artillery in front of the artillery is all transferred from the Guanning army!

The tragedy of this artillery battle can be said to be unprecedented in the Ming army, and the heavy casualties of the artillery have even exceeded the sum of all the major battles of the Chongzheng Dynasty! I don't know how Zhu Cijiong will feel after receiving the news, Lu Xiangsheng is here, and his face is already green.
