After taking inventory after the war, and after taking inventory of the city gates, everyone went to see the urn city together.

Speaking of which, this siege was a complete mess, and everyone lost their lives.

They didn't know there was an Wengcheng beforehand, and the siege team didn't bring ladders, so many people died in vain.

Wengcheng is a small circle. The walls of Wengcheng are much shorter than the outer walls.

Climb up to the urn city and take a look. From a high position, you can see every corner under the urn city clearly.

And because the Wengcheng was small, Zhang Fei said that during the siege yesterday, no matter where the thieves in this circle of Wengcheng threw stones, they could hit the siege spine.

This made Li Mengxi realize that the Wengcheng was different from an ordinary city wall that went straight down. An ordinary city wall could not limit the number of enemy troops attacking the city outside the city, but the Wengcheng was surrounded by a circle, which was equivalent to the Wengcheng being surrounded.

The size of the area is equivalent to limiting the range within which the enemy troops can gather.

Therefore, from the perspective of both siege and defense techniques, the fewer enemy troops gathered under the city wall, the smaller the pressure on the city head. For this reason, the defenders would build trenches in front of the city.

Set up sharpened wooden stakes.

But for the Wengcheng, after the Wengcheng is connected to the city gate, and the first city gate is broken, our army may have to block the city gate and fight with the enemy for a while. At this time, the Wengcheng is actually our battlefield.

Then, the open space in Wengcheng can gather more troops, which is actually an advantage for us.

In order to limit the number of enemy troops, it would be foolish to build the barbican into long and narrow corridors.

Of course, with this structure, after the enemy breaks through the first gate and then breaks through the second gate, the enemy's forces cannot expand too much. But at the same time, if we want to block the city gate and push the enemy back, then our side

The number of people who can unfold it is only as wide as the aisle, and the number of people is also small.

If the enemy and we deploy equal forces, then our side cannot have an advantage over the enemy.

Therefore, taking into account the fact that the city gate prevents enemy troops, the encircled area of ​​​​the barbican city should actually be larger.

In this way, after the enemy forces break through the gate, they will fight out from the city gate, and our army will gather in the urn city. As soon as the enemy forces break out, they will be surrounded by a large number of our people.

In this way, although the enemy forces broke through the city gate, they deployed manpower at the city gate opening. The passage was only as wide as the city gate opening, while our army's manpower occupied a large area of ​​width.

In this way, for a long time, the enemy troops coming in through the city gate hole will be surrounded by our army on three sides.

At the city gate, there is another favorable terrain for killing enemy troops.

Therefore, regardless of the size of the Wengcheng, there are big benefits to a big one, and there are small benefits to a small one.

The larger the area of ​​the urn city circle, the more people our army will gather in the urn city. When the enemy breaks through the gate and attacks from the city gate, our army's resistance will be stronger and it can strangle more enemy soldiers.

The area of ​​the Wengcheng is smaller. The advantage is that if the enemy successfully attacks the Wengcheng, they will have less manpower to gather in the Wengcheng. Later, the enemy will put ladders on the city wall and climb the wall to attack the Wengcheng.

There is less manpower.

The size of the barbican city each has its own advantages and disadvantages.

As for the size of the urn city, there is still discussion.

For an urn city with the same area, is it better to be wide or short, or narrow and long?

Width and shortness means that the Wengcheng is much wider than the city gate, but the distance from the city gate to the Wengcheng gate is shorter.

The advantage of this kind of wide and short urn city is that because of its width, when our army is blocked in the urn city, the horizontal rows will be long. If the horizontal rows are long, the enemy troops will fight out from the city gate hole and it will not be easy to open the situation from both sides.

At the city gate, the reason why our army has the advantage and can surround the enemy on three sides is because the enemy's troops are only a few rows of people outside the city gate, while our army has a large horizontal row of people surrounding it outside.

When the battle continues, the enemy troops will gradually rush forward to both sides. When the enemy troops rush to the city walls on both sides, then at this time, the enemy troops will be arranged horizontally like our troops. Our troops will lose the advantage of encirclement, and the enemy and we will be

It is relative to the square matrix.

Therefore, in this case, the wider the urn city, the better. The wider it is, the stronger our army's left and right flanks will be, and the longer it will take to surround the enemy's army.

At this time, the tactic of destroying the Wengcheng came into being.

Breaking down the enemy troops in the Weng City is different from breaking the formation, but it is about pulling back, destroying the enemies besieged in the Weng City, and clearing out the enemies in the Weng City. Therefore, after our army invades the Weng City, it is more important to break out from both sides than from the other side.

Middle protrusion.

Because the enemies on both sides are not eliminated, our army will always be surrounded and will always be at a disadvantage.

When our army can form a horizontal square formation in the Wengcheng, with no enemy troops on the left and right, our army will break the enemy's encirclement. At this moment, our army can most efficiently eliminate the enemy troops in the Wengcheng.

.

From this, he learned the art of guarding the Wengcheng.

When pulling back at the city gate, heavy armored elites should be placed on the left and right wings, and more manpower should be placed in the middle.

Because the space on the left and right wings is limited, the only way to increase strength is to improve the quality of the soldiers, while there is depth in the middle, so quantity can be used to ensure stability.

This is the same purpose as placing soldiers at the corners of the city wall when defending a city.

The advantage of the Wengcheng, which is wide and short, is that it can be surrounded.

As for the long and narrow barbican city, its advantage lies in the congestion.

That is, we are fighting against the enemy in Wengcheng. At this time, we are holding back in Wengcheng. Our troops are lined up horizontally. They are the same in number as the enemy's troops. Our army does not have any formation advantage. Our army's advantage is in Wengcheng.

Head. That is, more of our crossbowmen rely on the city head to kill and injure the enemy.

At this time, our army's formation is deep and has many manpower, so it can block the enemy in the Wengcheng for a longer period of time, and the enemy's army will be attacked by the city wall for a longer period of time.

The Wengcheng is wide and short, and our army's wings are thick and thick, giving it the potential to encircle.

The shape of the barbican is narrow and long, and our army has a long depth. It can block the enemy's troops in the barbican for a long time, and it has the potential to attack the enemy from the city head.

As for how to choose, careful consideration should be based on the city's conditions.

What does it mean to know what is appropriate because of the city? That is, depending on whether the city wall is tall or not, the city wall is the most advantageous location after all.

If it is a huge city, the city walls are high, and the urn city wall is also high. At this time, the city wall has a huge advantage, and it will be difficult for the enemy to climb the ladder to attack the urn city.

Therefore, at this time, the advantage of the city wall was higher than the advantage of encirclement. Therefore, the huge city and the urn city were narrow and long in shape, taking advantage of the city wall.

If the city wall is low, such as Wen'an County, Wen'an County has a low city wall, and if Wen'an County also has a barbican city, the barbican city wall will be even lower. At this time, if the barbican city is constructed in a narrow and long structure, then the enemy can easily defeat our army and encircle it on both wings.

Then they squeezed in, and then the enemy used a siege ladder to build it. Because the barbican city was very short, it was not difficult to attack the city. The enemy army soon reached the top of the city.

At this time, it is obviously impossible to use our army's crossbowmen at the top of the city to attack the enemy.

Therefore, if the city is short, the advantage of the city wall is far less than the advantage of encirclement. Therefore, the small city and the urn city should be in the shape of wide and short, and overlap the encirclement.

This is a trade-off.

As for building the urn city wide and long, it seems not necessarily appropriate. Because the bigger the city, the better. The bigger the city, the more manpower is needed for defense. A big city is conducive to the deployment of our troops on the city head, but it is also beneficial to

The enemy's siege forces deployed.

Especially in a dangerous place like the Wengcheng, bigger is not necessarily better. It is better to use every inch of space to the highest value. Therefore, there is a choice between wide, short, narrow and long.

As for the way to defend the Wengcheng, it is not much different from the way to defend the city wall.

Differently, there is no doubt that the section of the Wengcheng adjacent to the city gate will be attacked by the enemy first. The enemy troops rush out from the city gate and can attack here directly.

Therefore, the Wengcheng walls on the left and right sides next to the city gate opening are the weakest points.

The first way to strengthen this weak spot is to put elite soldiers, strong bows and powerful crossbows here to increase the defensive strength; the second is to give priority to supporting this weak point with gold juice from beating stones to increase this weak point.

The third is, when the siege soldiers take turns to rest, the rotation should be more frequent here so that the defenders always have sufficient physical strength; the fourth is, when building the city, the stairway can be built here, and the enemy troops can board the city from here.

, being surrounded on three sides, further increasing the difficulty for the enemy to climb the city. The stairs are close, and our army can quickly reinforce the city, which also increases the resilience of the city. Fifth, an arrow tower can be built here. Several layers of arrow towers can accommodate dozens of people.

, which is equivalent to greatly increasing the defensive manpower here.
