The reason why Dolgon chose Xiluo City to attack, instead of attacking the main city of Shanhaiguan and the northern wing city and Dongluo City garrisoned by the Ming army under Wu Xiang, seems to be a bit unreasonable, after all, the combat effectiveness of the Ming army under Wu Xiang is obviously weaker than that of the Dazhong army guarding Xiluo City, and it seems a little unwise for him to choose to attack Xiluo City.

But Dolgon is not a reckless person, the reason why he chose Xiluo City to launch a fierce attack is his reason, first of all, from the geographical advantage, the main city of Shanhaiguan, the north wing of the city and the three cities of Dongluo City were built in the early years, after so many years of continuous repair of the Ming Dynasty, now it can be said that the city is strong, and Xiluo City was only built in the past two years, because the Ming Dynasty was financially embarrassed, Shanhaiguan was not rich, the main generals stationed here have rotated more frequently over the years, and no one is willing to really work hard to step up the construction of Xiluo City, so Xiluo City is still a semi-finished product to this day, and all the buildings have not been completely perfected, so Xiluo City is obviously far less solid than the other three cities compared to the three cities that Wu Xiang was responsible for guarding.

In addition, in terms of troops, Wu Xiang is only responsible for the main city of Shanhaiguan and the north wing of the city of Dongluocheng, the Ming army under his command is basically concentrated in these three cities, the defensive area is relatively small, and the troops are relatively sufficient, so although the combat effectiveness of the Ming army is a little worse, but the advantage in strength makes up for their disadvantages, compared to the defense line of the large Chinese army, their defense area is much smaller, and the three cities just form a corner of the momentum, attacking any of them, will be bombarded by the artillery of the other two cities, so it is more difficult to attack, This is also the reason why Wu Xiang played a slippery head at the beginning, handing over Xiluo City and South Wing City to Yan Chongxi to be responsible, and to some extent, he still wanted to spare the troops and save some of his strength, which is also understandable.

Another very important reason is that Dolgon has found that the Ming army under Wu Xiang is not as bold as the Dazhong army, during this period of time when he attacked the city, only the Dazhong army dared to go out of the city to counterattack, the Ming army only dared to be trapped in the city, did not dare to send troops out of the city to counterattack once, so Dolgon was worried that if he concentrated his troops and firepower to attack the three cities defended by the Ming army, then it was not possible for the Dazhong army to make a hindrance from it and attack his Jiannu army from the side.

Therefore, after combining various reasons, Dolgon decided to concentrate his forces and fire on the city of Ciro, which not only shows that Dolgon is not a fool, but also shows that Dolgon is a very clever slave.

Jiannu's actions immediately attracted the attention of the defenders and the two armies, and once again immediately began to set up defenses, transporting a large number of guards and weapons onto the city walls, and preparing to deal with them.

This time, Dolgon did not rush to send troops to attack, but first concentrated all the artillery available in his hand, concentrated his firepower on the city of Silo to launch the most fierce artillery bombardment ever, and the time of this shelling lasted almost an hour, and all kinds of shells fell on the area of Ciro City like hail.

The gunners of the Dazhong Army and the heavy artillery of the Ming Army also immediately launched a counterattack, and the artillery of both sides almost did not stop for a moment, and the bombardment lasted for nearly an hour, which can be said to have their own losses, and even to some extent, the losses of the Jiannu side in the artillery battle were even greater.

But for the defenders of the Dazhong Army in Xiluo City, it can be described as a disaster, under the artillery fire of Jiannu, almost all the shells were concentrated in the cramped place of Xiluo City, although these days, Yan Chongxi has also mobilized people every day to strengthen Xiluo City, but after all, this is only a temporary measure, and has not fundamentally changed the status quo of Xiluo City's lack of strength.

This time, Jiannu concentrated artillery artillery bombardment of Xiluo City, an hour down, not only the Dazhong soldiers defending the city will suffer heavy casualties, the north and east city walls of Xiluo City, also under the bombardment of heavy artillery, the city bricks that have not been wrapped are almost all peeled off, only the rammed earth city wall below, and the rammed earth city wall is also under shelling, began to collapse, some places have collapsed, there are gaps.

Even Yan Chongxi himself, who was in command in the city of Xiluo, was hit on the head by the stones stirred up by the shelling, and fainted under the city wall with serious injuries, and was hurriedly snatched down by his guards and sent to the medical camp for rescue.

Yan Chongxi himself and the generals did not expect that Jiannu would change this style of play today, and the density of artillery bombardment in Xiluo City was so large, and the ideological preparation was not very sufficient, so after the start of this battle, the situation in Xiluo City became very tense.

Luo Li was not with Yan Chongxi in Xiluo City, but he soon saw Jiannu's intentions, so he ordered his gunners to fight back and support Xiluo City, and it didn't take long for him to learn that Yan Chongxi's heavy artillery was injured and had been carried down for first aid, so Luo Li did not shirk, and immediately handed over the matter at hand to his generals to be responsible, and personally rushed to Xiluo City to sit in defense.

When he saw that the walls of Xiluo City had begun to collapse, Dolgon laughed wildly, and shouted loudly to order Li Shutai, Liu Zhiyuan, and Wu Shoujin, the three banners of the Han Army, to personally lead their troops to start the final blow against Xiluo City, in order to make a contribution in the first battle, first defeat Xiluo City, and then expand the results of the battle.

The three big traitors had no choice but to go to their army, shouting and began to command their subordinates to attack, these Han soldiers arrived at this point, in fact, they didn't want to sell their lives for Jiannu, but they had no choice, after all, their families were still controlled by Jiannu outside the pass, they would be killed if they didn't fight, and their families would be affected, so they had no choice but to be ordered to attack.

Batches of heavy carriages were pushed out by the Jiannu army and arranged at the front of the line, and under the impetus of countless soldiers, covering more Jiannu troops began to attack Xiluo City.

Although the defenders' artillery fire kept bombarding them, from time to time the oars would be hit by shells, turning into fragments and scattering in all directions, and the slave soldiers who pushed the oars suffered heavy casualties, but under the supervision of the three big traitors, these Han soldiers could only reluctantly continue to advance, and constantly replenish the oars to the gap and restore the defense line of the oars.

Moreover, after the artillery of the Jiannu army collapsed part of the city wall of Xiluo City, they turned to shell the defenders on both flanks, trying to suppress the artillery fire of the defenders.

In terms of the speed of artillery bombardment, the defenders, especially the gunners of the Dazhong Army, had an absolute advantage, and their whole charge packages played a decisive role, making their loading speed much faster than that of the Jiannu Army, so in the short artillery battle, the Dazhong Army could overwhelm the Jiannu Army.

But there is a problem with the artillery at this time, that is, after the cannon is fired, the barrel will soon overheat, which will cause the spontaneous combustion of gunpowder, so after the artillery of both sides for a period of time, the cannon must be rested for a while, and it can be loaded and fired again after cooling down, so that after the two sides have been fighting for more than an hour, the artillery fire has to stop, otherwise the consequences will be very serious.

At this time, both sides had the phenomenon of cannon explosions, which caused many casualties among the gunners, and the defenders had to order a temporary fire out and wait for the artillery to cool down.

Seeing that the defenders' artillery fire became sparse, taking advantage of this opportunity, a large number of Jiannu troops frantically pushed the carts, covering more slave soldiers and began to approach the city of Xiluo, this time Dolgon, Duoduo can be regarded as a big decision, and did not hesitate to strengthen the two white flags under their command of the Gebush Xian battalion into the attacking soldiers and horses, one is to make it act as an archer to cover the attack of the Han army, and the other is to play the role of supervising the battle, supervising the attack of the Han soldiers of the Wuzhen Chaoha battalion, once someone refuses to work hard, they will be shot on the spot.

In addition to the banner generals of the Han army of the three banners, the Mongolian soldiers of the two Mongolian Eight Banners were also strengthened into the attacking team, forming an echelon attack formation, and even the Korean musketeers who were transferred from Korea were also driven into the attacking team, including the young men among the captured Han people were also ordered to push the cart or raise a large shield to cover the attack.

In short, Dolgon is determined, no matter what the cost, he must also take Ciro City, open a gap in the Shanhaiguan defense line, and let the emperor Taiji behind him see, he Dolgon is not a wine bag and rice bag, in this Qing Dynasty, his three Dolgon brothers are also well-known figures, and no one is allowed to despise them.

Seeing that the artillery could no longer stop their attack, the firecrackers began to line up on the wall and began to fire at the attacking Jiannu under the city, even Wu Xiang had already sensed Jiannu's thoughts at this time, and did not hesitate to take out a batch of rockets at the bottom of the box, put them on the city wall, and began to ignite, overwhelmingly shooting towards the Jiannu army outside the city.

Rows of muskets and bushes of rockets were fired, and the Jiannu soldiers suffered great casualties, but their carts and shields also blocked a lot of bullets, and they successfully covered the attack of the Jiannu army.

The distance between the two sides is getting closer and closer, and the defenders' musketeers also begin to aim and shoot non-stop, the Jiannu soldiers are very frightened, and they will be knocked to the ground by a bullet if they are not careful, they can only lie on the back of the cart, and step forward, and the soldiers behind them try their best to stick behind the big shield, or simply hold their shields to cover their upper body, crawling forward like turtles.

As the distance narrowed, the Jiannu side also began to counterattack the defenders of the city, using various firearms, bows and arrows in their hands, they continued to lean out from behind the cart and fire at the city.

(Wow!) Plenty of tips today! Special thanks to the unhappy coward, Donggong, and the three brothers of a drunken man for their generous rewards! Thank you for the cold wind! ）
