There is quite a lot of discussion about defending the city in the Chinese art of war, but in any case, there is a point that should not sit back and watch the enemy besiege the city, but should take the initiative to attack appropriately in order to boost the morale of the officers and soldiers defending the city. However, this could not be achieved at all in the Battle of Anyang, and Yinxiang could only watch as the Xia army first dug a trench, then built a breast wall, and then used cement to turn the breast wall into a real city wall.

The main reason for Yinxiang's passivity was, of course, because the Xia army had more soldiers and more artillery - the large number of soldiers meant that the degree of digging trenches and building the chest wall was fast enough, and the Qing army did not even have time to react, and the Xia army had completed the siege fortifications around Anyang; The large number of artillery means that no matter which gate the Qing army kills from, it will be bombarded with at least 150 artillery pieces - and what makes Yinxiang most angry is that a considerable part of these artillery pieces are abandoned by the Qing army itself.

In fact, in the Northern Expedition of the Xia Army, not counting the urban defense artillery weighing thousands of catties on the heads of the cities and the green battalion equipped with Hongyi cannons, big Buddha lang machine guns, and tiger squat cannons, the internal and external firearms battalions built by Kangxi alone with huge sums of money dropped more than 700 Wucheng Yonggu General Cannons and Shenwei General Cannons.

Don't look at the caliber of these cannons is very large and the texture is excellent, but in fact, they do not meet the equipment standards of the Xia Army as well as those built and flag-made artillery, so sooner or later there is only one way to return to the furnace, but before they are turned into copper water again, the Xia Army will naturally have to wave out all their residual heat, not to mention anything else, at least those shells and gunpowder that also do not meet the standards of the Xia Army must also be consumed at one time, and Anyang is such the best place to use.

Naturally, the Xia army could also travel thousands of miles to transport the captured Qing army's heavy artillery to Taiyuan, which was also undergoing siege warfare, but the road to Jin was not much easier than the Shu Road, which was difficult to go to Qingtian, and the Xia army had to give up the distance and seek the near, first squandered as much as possible in the battle of Anyang, and it was really useless, so it was transported to the next battlefield.

"Next, each division should dig a longitudinal trench, and after fifty steps, expand to both sides, and finally form an inner ring trench and a breast wall, at this stage, the artillery army should pay attention to prevent the Qing army from leaving the city." The military Sima beside Sun Yu was engaged in a high-pitched arrangement. "The Holy One is sympathetic to the soldiers, and I don't want to see any more senseless sacrifices before the recovery of the whole country, but we can't relax, we must tighten the noose round by round, and finally put the cannon directly under the nose of the Qing prisoner." After Jun Sima Zhi finished speaking, he looked back at Sun Yu, and the big man who was already scheduled to enter the Privy Council nodded faintly, so Jun Sima Cheng ordered for him. "Please adults, act immediately, there are thousands of artillery, and you must not fall behind Taiyuan and trap the city."

Xia Jun was busy again, watching the Xia army continue to dig forward like ants, the Qing army couldn't sit still, the left wing of the internal firearms battalion, the deputy commander of the Yellow Flag Manchuria, Da Luo, said to Yinxiang: "Thirteen elder brother, Xia Jun is hateful, don't fight with the gentlemen but want to dig the soil and dig under the root of the city wall, this is not good, once their cannons are transported to the city, the cannons in the city can't hit them, Anyang is dangerous, and they still have to attack." ”

"Sortie? The artillery of the Xia army blocked all the gates, and as soon as they went out, they bombarded all over the world, even the iron bumps were broken, not to mention that the sons and daughters were all from meat. "The deputy capital of Manchuria with a white flag, Wu He, shook his head immediately when he heard Darlow's words." Thirteenth Master, this is a plot by the sea to lure our army out of the city, and it is to use artillery fire to consume our soldiers defending the city. ”

Thinking about the more than 1,000 wounded soldiers in the city who were waiting to be killed because of lack of medical treatment, all the Manchurian civil and military officers shook their heads in unison, saying that they couldn't be hard to use up with the Xia army's artillery fire, but Daluo didn't give up, he said: "Why don't you attack at night, the Xia army's artillery is always not so accurate at night." ”

Yinxiang thought about it for a while, and felt that he really couldn't watch the Xia army's trenches expand inward one by one, so he agreed to the night attack.

After nightfall, several city gates in Anyang were slightly opened, and groups of Qing troops quietly slipped out of the city gates, crossed the suspension bridge and went straight to the fortifications of the Xia army. Fearing a possible night attack by the Qing army, the Xia army collected the troops at night, so the Qing army appeared unimpeded at the second trench that was still being completed, and then worked hard to backfill the soil dug up by the Xia army. Seeing that it was almost completed, the Qing army did not follow the longitudinal trench to the Xia army's chest wall, turned around and fled, leaving only the Xia army's wolf in one place.

After dawn, Xia Jun watched in amazement that his few days of labor had been ruined by the Qing army overnight, but Sun Yu ordered them to continue digging. Well, the military order cannot be violated, so keep digging. Of course, this time the Xia army had an eye, and left an observation post on the front line at night in case the Qing army came to destroy it again.

The Qing army still came, and saw that the Xia army dug for another three days and re-excavated the original damaged part, and Yinxiang had to send a night attack force again. As a result, when the city gate was opened, because it was just a crack, the Xia army guard did not pay much attention to it, but the movement of the suspension bridge was too big, and it was impossible for the Xia army not to show abnormality.

So when the Qing army resumed the work of filling the earth, the Xia army immediately shot at the demarcated area. Because the Xia army had too many artillery, and could shoot wildly regardless of the cost, so from the trench area to the front of the Anyang city gate nearly 500 Huaxia steps of the area turned into a sea of fire, out of the city Qing army did not have time to escape, most of them fell under the artillery fire, only a small number of smart people chose to run to the corner, only after dawn to escape back to the moat by the Qing army in the city to rescue.

However, this defeat did not discourage the Qing army's plan to destroy the trench, Yinxiang quickly opened a few more holes in the city wall of Anyang, sneaked out of the place where the Xia army guard post could not observe, and then crossed the moat with a buoy, broke into the trench from an unexpected place, killed the guard post and refilled the trench.

The Xia army soon showed the tricks of the Qing army, so they set up additional guard posts in more places, and scattered some artillery, and soon let the Qing army return with the next attack. But Yinxiang, who refused to admit defeat, quickly changed his tactics, he first sent a number of sharp soldiers to sneak out of the city, swim across the moat, infiltrate the Xia army's guard post, and after all the sneak attacks were successful, he sent troops out to fill the trenches, and once again destroyed the achievements of the Xia army in a few days.

As the saying goes, the road is three feet high, the magic is one foot high, and the Qing army used the means of attacking and killing the Xia army's outposts, so the Xia army responded by sending light and dark double guard posts, so a few days later, it gave the Qing army a painful blow to the attacking troops.

Yinxiang finally ran out of way, the exchange ratio between the two sides was too disparity, the Qing army killed the Xia army's guard post only to kill dozens of people at a time, the Xia army shelled at a time, at least the Qing army could lose two or three thousand people, Yinxiang was only 70,000 people in total, and after three or four failures, more than 10,000 people were either killed or injured, and how many times could he squander it next?

As a last resort, the Qing army in Anyang City could only watch the noose that hanged them tighten day by day.

However, the Qing army temporarily stopped, and the Xia army did not do it. Therefore, as long as the wind direction and wind strength are appropriate, Xia Jun will light Kong Ming lanterns and use the wind to send all kinds of propaganda materials into Anyang City. These propaganda materials include texts, pictures, announcements of the true achievements of the Xia army, and fabrication of Kangxi's posthumous edicts. At the beginning, the Qing army was still very nervous, for fear that it would shake the morale of the army, but later it was not strange, and even regarded these propaganda materials as spiritual reading materials to spice up the boring life.

Since the propaganda materials were not very effective, Xia Jun came up with new weapons. The so-called new weapon is a rocket, of course, this is not the kind of rocket that ties a piece of cloth on the arrow and then ignites it, and it is more like a firework put into the air in a certain way, but the shell of the firework is mostly paper, while the shell of the rocket is a thin iron sheet. However, it is precisely because of the weight of the shell that the firing range is quite limited, and it can only shoot 50 to 80 Chinese steps, which is far inferior to the range of artillery.

Some people say that since it is not as good as artillery, why should it be installed, but this is what Zheng Kezhang meant, and the Ordnance Department of the Ministry of War can only make fun, but it has basically not been used after being equipped, and this time it is the first to try it in Anyang City.

On September 18, the 14th year of Huaxia Wucheng, that is, the fourth day after Kangxi**, the second trench of the Xia army, which was one hundred and twenty Huaxia steps away from the first trench, was encircled. Twenty days later, the third trench, which had been dug one hundred and fifty paces forward, was completed again. It's just that instead of being solidified like the first two, the completed part of the breastwork wall is not solidified like the first two, but is carried by baskets collected from all over the surrounding areas, and it seems to be stacked randomly under the guns of the Qing army.

Two hundred and thirty Huaxia steps, converted into the Qing system, is more than two miles, which is completely within the firing range of the Wucheng Yonggu General Cannon owned by the Qing army, so the Qing army immediately opened fire on the chest wall. However, to the surprise of the firearms battalions inside and outside the Eight Banners, although the artillery fire dispersed some of the earthen baskets, it did not cause damage to the main structure of the breastwork, and the Qing army was limited to the limited amount of ammunition and could not continue to shell a pile of soil, so they had to watch the Xia army clean up at night and reappear the next day with a complete earthen basket embankment.

Just when the Qing army in Anyang City was puzzled and thought that the Xia army had used witchcraft, the Xia army, who had been on duty in shifts, began to continue to dig forward again, this time digging forward one hundred and fifty steps, so that it was only a hundred steps away from Anyang. Unless it happens to enter the trench, the artillery is ineffective against the trench, as for sending troops to drive away, the long-range artillery of the Xia army has been stationed at the second breastwork, but it is within the range of others, and it is clearly to die. What to do? I had to hope that the heavy snow would fall and freeze Xia Jun to death.

To the disappointment of the Qing army, the snow fell, but the Xia army continued to dig the frozen soil despite the cold.

On October 26, the fourth trench was encircled, and the Xia army immediately dug several smaller communication trenches forward.

Three days later, these deliberately dug single passages had arrived crookedly less than fifty paces away from the moat outside Anyang City, and the Qing army could almost see the movements of the Xia army as they dug horizontally on both sides. But for such a small communication trench, the Qing army, which had turned a blind eye, was only regarded as an observation post in front of the Xia army, so it was not very vigilant - but think about it, Anyang City's movements had long been unable to escape the observation of the Xia army, so what difference was there between one more and one less observation post.

On the night of 29 October, the Xia army transported 4,000 new rockets into these positions, which looked like observation posts. 4,000 rockets, evenly spread to eight firing positions, is only 500 in each place, but the momentum of this new rocket is terrifying. When a group of ten rockets rose into the air together, eighty meteors appeared repeatedly in the night.

Some of these fire meteors flew low and crashed into the city wall, and then exploded on the ground, and some flew high and fell into the city, which immediately caused a fire, and the most coincidental was just the enemy tower and lookout post in the middle of the city, which quickly turned into a torch, and even ignited the gunpowder accumulated on the city wall, causing an earth-shattering explosion.

Seeing that the power of the rocket was so huge, it seemed that the first-line shooter of Xia Jun, who had got a fun toy, was tired of shooting out all the rockets in groups, and Anyang City was completely chaotic??????
