The last three kingdoms

Chapter 1191 Authentic Siege
The failure of attacking Zhiyuanguan was a heavy blow to Sun Xiu. Sun Xiu was originally full of ambition and full of confidence in this Northern Expedition. As long as he wins this battle, Sun Xiu's status in Wu Kingdom will definitely be improved. Great improvement.

But the reality is extremely cruel. In the battle of Yuanyuan Pass, Sun Xiu's entire army was almost wiped out, and suffered a devastating blow, which made Sun Xiu feel ashamed.

Originally, Sun Xiu's position in Wu State was already in jeopardy. If he lost this time, it would just give Sun Hao an excuse. Even if Sun Xiu could escape back to Jiangdong by luck, he would definitely not be able to escape Sun Hao's punishment.

The ants were still alive, but Sun Xiu didn't want to die for the country just like that. Seeing the Han army surrounded heavily, Sun Xiu immediately gave up the idea of ​​resisting, and ordered his men to raise a white flag to surrender to the Han army.

After Jiang Bin saw the white flag raised by the Wu army, he ordered the Han army to stop attacking and accept their surrender.

Sun Xiuling's subordinates tied him up and came straight to Jiang Bin. Jiang Bin jumped off his horse and untied Sun Xiu himself.Jiang Bin and Sun Xiu had played against each other, and they were equal in chess. Jiang Bin naturally admired Sun Xiu. At this time, when Sun Xiu surrendered, Jiang Bin treated each other with courtesy, which moved Sun Xiu very much. Sincerely surrender.

The entire army brought by Sun Xiu was wiped out. When the news reached Luyang, Wu Yan immediately led his troops to turn around and flee south. He only had about [-] troops under his command. No matter what, he would not be able to defeat the Han army. If he did not seize the opportunity and flee If the Han army kills them, it may be too late to get up and go again.

Jiang Bin, who had won a complete victory, was not too interested in Wu Yan's remaining troops, and let him flee south, instead of chasing him, he sent someone to report to Liu Yin immediately.

The Battle of Luoyang has lasted for several days. Wu Jun mobilized all available forces and launched round after round of strong attacks on Luoyang City. The battle was very fierce. Wu Jun's corpse, in order to conquer Luoyang, Wu Jun also paid a lot of price.

However, how can the Wu army conquer such a towering and solid Luoyang city in such a short period of time? The Han army tenaciously guarded every section of the city wall. Even though the Wu army's offensive was like a storm, Luoyang city was still as firm as a rock. , standing still.

Sun Xin served as the vanguard and was responsible for commanding the siege operations. Although he tried his best, he still couldn't even get to the top of Luoyang City. As it got closer, Sun Xin's siege made no progress at all, and he had to pin all his hopes on Sun Kai's authentic way of attacking the city.

There are two ways to attack the city with tunnels. One is to dig the tunnel directly into the city and leave the exit in a hidden place. When the night is quiet, send soldiers to sneak into the city through the tunnel, and then cooperate with the inside and outside to take down the city; The second is to dig the tunnel under the city wall, hollow out all the soil under the city wall, and then support it with wooden piles. After the construction is completed, when the engineers withdraw, the wooden piles are ignited. Once these wooden piles are burned into ashes, Then the foundation supporting the city wall does not exist, and the city wall will sink and collapse.

These two methods have their own advantages and disadvantages. The first method requires a detailed map of the city. When the tunnel is excavated into the city, it is necessary to avoid streets, military camps and other key areas. In the other side's military camp, it would be a big joke.

The expected effect can only be achieved if the tunnel entrance is set in a relatively hidden place, and all of them go to the city to coordinate carefully.

The advantage of the second method is that it can quickly destroy the opponent's city wall and create a gap so that the siege infantry can enter the city along this gap.But its disadvantage is that there are often more than one wall in many big cities. When the outer wall is destroyed, the inner wall can still prevent the attack.Moreover, if the number of defenders is sufficient, it is possible to repair the damaged city wall by stacking sandbags, wood and stones.

And Luoyang City has such a defensive structure, which also made Sun Kai dare not aim at destroying the city wall from the very beginning. He had to dig tunnels to enter Luoyang City and send out surprise troops to win.

In this way, the manpower and time required to dig the tunnel will increase. Fortunately, the Wu army has enough soldiers, so there is no need to worry about the shortage of manpower. It is just that ten days are very tight. All previous efforts may be wasted.

For this reason, Sun Kai personally supervised, dispatched additional manpower, implemented the method of excavating several groups of people in turn, and worked day and night to speed up the progress.Since the excavation site chosen by Sun Kai was located inside the camp, it was covered by tents, and it was almost impossible to see anything from the city.

What's more, Sun Kai has always been cautious, and he didn't dare to be careless in the slightest. He even piled up the new soil dug out every day in the tent, and then secretly transported it out when it was dark.

Sun Kai had to be careful, after all, tunnel siege was time-consuming and labor-intensive, and the game was a surprise victory. If the defending army had mastered the siege action in advance, then what awaited them would be almost a catastrophe.

Now that time is running out, Sun Kai can only dig out a tunnel that leads directly to Luoyang City.Fortunately, Wu Guoxiozuo, who has been lurking in Luoyang City for many years, provided them with a detailed map of Luoyang City, allowing Sun Kai to understand the situation in the city relatively easily and choose a proper exit.

Digging a tunnel is a systematic project. Even with a map in hand, there is no guarantee that the designated location can be dug at the entrance of the tunnel. After all, a tunnel that is several kilometers long cannot avoid some deviations, sometimes by the slightest difference. Absurd.

But Sun Kai had no choice now, he had no choice but to bite the bullet and continue. His greatest hope now was to reserve the tunnel entrance at a suitable location, so that it would be convenient for Wu Jun to launch a sneak attack.

In order to increase the concealment of the sneak attack, Sun Kai decided to change the plan. The original plan was to dig an exit in the city, but now it seems that only one exit is far from meeting the requirements, so in Sun Kai's drawings, another Two exits were added, both of which were located in relatively remote places in Luoyang City.

As time went by, the tunnel was extended day by day. Since Sun Kai chose some strong soldiers, they were indeed more powerful in their work. Now the tunnel has been dug under the city wall of Luoyang , and then dug in, they dug into the city of Luoyang.
