In ancient siege warfare, if there was no special means to break the city, you could only rely on the means of forcibly attaching ants to the siege, and the time was often not fast.

It is very likely that the siege of the army will gradually become a drag on the grinding of foreign workers because of the unfavorable battle ahead, that is, the siege soldiers in front seem to be lively in the siege, but in fact, it is just a light thunder and no rain.

Therefore, if there is a defeat in the front during the siege, the morale of the battle must be adjusted, otherwise no matter how much the rear is urged, there is no way to make the front-line siege soldiers have any special actions, they will only find a way to waste time to survive.

At the same time, normal siege warfare, even if it starts in the morning and continues to attack in the evening, in fact, a lot of time is not spent on the siege.

For example, when an army is sent to attack a city, the army will set off from the camp to the city that needs to be attacked, and it will often take more than half an hour, unless you are building a camp close to the city, but this is likely to be counter-raided by the defenders in the city at any time, which will cause the camp to roar and cause chaos.

Therefore, the army will often camp a certain distance away from the city, and it is almost at 9 o'clock in the morning when the troops are dispatched, and when they really set up a siege formation in front of the enemy's city, it may be already 11 o'clock at noon.

Next, in the process of attacking the city, the siege soldiers rushed to the front of the city to construct a siege formation, and then assigned a siege team to attack, which also consumed time.

When the sun goes down, it is basically time to collect troops and return to the camp, and there are very few people who attack the city day and night, so there is not much time to really spend on the siege.

The more well-trained and elite an army is, the less time it takes, and the more time it takes if it is a rabble.

At the same time, the defensive intensity of the city to be attacked and the strength of the defenders will also have a great impact on the siege war, for example, more than 1,000 Wei troops led by Hao Zhao, the defender of the Wei army in Chencang City, resisted Zhuge Liang's Northern Expedition for nearly a month, but Zhuge Liang was short of food and grass, so he had no choice but to withdraw his troops.

Among them, the Wei general Hao Zhao's ability to defend the city is not to mention, and the special terrain of Chen Cangcheng is also the reason why the Shu army cannot give full play to the advantage of attacking the city in numbers.

The location of Chencang City built by Hao Zhao is very dangerous, it is a prominent piece of high ground, the west, east and south are steep platform walls, and the city wall is five or six zhang high, so it can become a fortified city that is easy to defend and difficult to attack.

Of course, another reason why the Chencang defensive battle failed to break the city may be that Zhuge Liang did not pay too much attention to the Northern Expedition this time, so he only prepared military rations for a month.

According to the analysis of later generations, Zhuge Liang's hasty organization of the Northern Expedition this time was actually to respond to the request of Eastern Wu to help contain the Guanzhong army of the Northern Wei Dynasty when the Northern Wei Dynasty conquered Eastern Wu, so that the Northern Wei Dynasty could not mobilize the Guanzhong army to join the battle of Wu.

Therefore, Zhuge Liang did not launch a full-army attack on the small city of Chencang, but only used various siege equipment, as if playing a siege exercise, and in the end, although it was a little regrettable that he could not capture Chencang and retreated, Zhuge Liang also achieved the strategic goal.

But I have to say that if the siege cannot be won by surprise, it is indeed not easy to conquer.

Now Pang Xi, the defender of Jiangzhou City, has more than 30,000 Shu troops available to defend the city, and the terrain of Jiangzhou City has also increased the difficulty of attacking the city, so it is naturally not so easy to be captured.

However, Gan Ning and Zu Lang refused to let their regular army easily consume on the battlefield of this kind of ant-attached siege, but only sent those barbarian warriors who lacked training and were like a rabble to attack the city, which slowed down the siege even more.

It is not easy to climb the city wall by means of ants to attack the city, not to mention that after the city wall, you have to break the city gate to enlarge the army into the city, which is even more difficult to achieve.

Originally, if the trained soldiers of Gan Ning and Zu Lang's own army were used to attack the city, it might still be a bit threatening, but now that it is replaced by those barbarian warriors who lack training, the efficiency of the siege is simply half the effort.

So the war dragged on, and it was still in a stalemate for a while.

But this is also just a strategy, in fact, in this battle of Jiangzhou City, Gan Ning, Zu Lang, and Pang Tong have already set a tactic of encircling but not attacking, that is, they are ready to exhaust the grain and grass of Pang Xi's army in Jiangzhou City, and they can take Jiangzhou lightly without a fight.

This time, the more than 30,000 Shu troops led by Pang Xi can be regarded as the main army under Liu Zhang's account in Yizhou, if this Shu army can be taken and Jiangzhou City is captured, it will also open the gateway to Chengdu City.

The next step is to enter the Chengdu Plain, and the soldiers will directly point to Liu Zhang's lair in Chengdu, without encountering too steep mountain terrain.

Therefore, now more than 30,000 recruited barbarian warriors are now driven to attack Jiangzhou City, on the one hand, it is to consume the number of some barbarian warriors, and on the other hand, it is also to train the siege tactics of these barbarian warriors, so as to prepare for the next drive to attack Chengdu.

Originally, Zhu Wei's side was a little jealous of the number of these barbarian warriors, but now he can take the opportunity to consume some, and at the same time, the battlefield is also the best place to train troops, maybe these barbarian warriors can know how to cooperate with the battle array.

In addition, driving the barbarian warriors to attack the city in this way can also give Pang Xi a false impression, so that he will not discover the tactics of Zhu Wei's army in the first place, and by the time he really finds out that the situation is wrong, it will be too late.

Compared with Gan Ning and Zu Lang in this expedition to Yizhou, if they can go down to Jiangzhou without a fight, they can get the elite of the 30,000 Shu troops in Jiangzhou City out of thin air, and they can also increase their own troops in the end.

Anyway, in the rear of Gan Ning and Zu Lang's army, there are sufficient supplies of grain and grass provided by the four counties of Jingnan and Yuzhang County, and the 30,000 barbarian soldiers don't need to feed them too well and too full, so that Gan Ning, Zu Lang and Pang Xi in Jiangzhou City can afford it.

For this reason, Gan Ning sent warships as early as the first time to send Zulang's cross-mountain battalion soldiers and horses to the surroundings of Jiangzhou City, blocking the road from Jiangzhou City to other places, and blocking Pang Xi's way to escape.

After all, Jiangzhou City is a waterway transit city facing the river, and it was originally developed by relying on commercial transportation by waterway, and it does not have much grain production in the fields, so it is naturally impossible to produce food self-sufficiently in such a state of war.

Before Pang Xi successfully attacked Jiangzhou City, so Pang Xi's army did not bring much food from Chengdu.

Under Pang Tong's calculations, Pang Xi's army of 30,000 only had two or three months' worth of grain in Jiangzhou City at most, so it was expected that Jiangzhou City would be taken early next year.

The land route around Jiangzhou City has been blocked by Zulang's mountain camp, and the waterway is blocked by Ganning's Jiangjiao camp.

Such tactics can also have a strategic impact, that is, the war on Yizhou's side has reached a stalemate, which can make everyone in the world think that Zhu Wei's military focus is still limited to Yizhou, which can also make Cao Cao and Yuan Shao more relaxed their vigilance.

Therefore, after the discussion of his military advisors and strategists, Zhu Wei's side also agreed with the siege tactics of Gan Ning and Zulang's army in Jiangzhou City......
