Many cities are often built in this way, the direction of the city gate is always the most open place, the city wall connecting the city gate tower, most of them are built in dangerous places, and the lot suitable for the large group of people to attack the city is near the city gate tower.

Tongguan City is even more so, in addition to the relatively open terrain of the place where several big city gate towers are located, the city wall connecting the city gate tower is built in the place where the mountain is dangerous, the city wall is built very tall and precipitous, some places do not say people, even apes can not climb, the rebels who attack the city want to attack the head of Tongguan City, except to attack from the direction of several city gates, there is no other way.

Unless there are special forces or special reconnaissance units similar to those in the era in which Yang Xi lived in the later generations, with outstanding individual combat capabilities and an overall attack power, they may be able to use various special equipment to infiltrate the city from other directions and reap huge victories in small-scale special operations. But in the Tang Dynasty, there was basically no such possibility, unless Yang Xi trained a special force.

The walls connecting the gates were not guarded by sergeants, and there were sergeants guarding and watching everywhere to prevent small groups of possible rebels from climbing the mountains and lurking over the mountains. However, the number of sergeants guarding the walls was very small, and it was almost only for guarding.

Due to the obstruction of a large number of rebel dead and wounded sergeants, the follow-up charge of the rebels did not go well, and the fighting in the direction of the east gate tended to ease compared to the beginning. This was very unexpected to Yang Xi, and of course it also surprised and anxious Cui Qianyou, who was observing the progress of the war on the distant mountain.

Seeing that the men and horses attacking in the direction of the east gate were dealt a devastating blow, and a large number of dead and wounded sergeants blocked the road, and there was no way to speed up the attack, Cui Qianyou knew that if he wanted to capture Tongguan City today, he should not expect to break through from the direction of the east gate.

This made him feel very heavy, and faintly gave birth to pessimistic thoughts.

He knew that in the case of a complete superiority of his own forces, the best way to attack the city was to launch a large-scale and all-out attack, blossom at multiple points, concentrate a large number of soldiers at each point, and use the advantage of troops to put the greatest pressure on the defenders at the head of the city, so that the defenders at the head of the city would be overwhelmed and suffer heavy casualties. In this way, more soldiers can rush to the top of the city, directly engage the defenders in hand-to-hand combat, and also use the advantage of strength to occupy the city, and finally capture the city. But now, there is no way to spread out the attack surface, only the south gate direction can be launched on a large scale, and the north gate direction cannot even arrange the attack forces, and the situation in the east gate direction does not seem to be suitable for a large-scale attack.

can only increase the intensity of the attack in the direction of the south gate, regardless of the loss of the sergeants, and even completely fill in the forbidden ditch with corpses, which will give more sergeants a chance to enter the city, Cui Qianyou sighed faintly.

At the thought of filling in the forbidden ditch, Cui Qianyou couldn't help but be shocked.

Yes, if there is no forbidden ditch, more men and horses can be concentrated in the direction of the south gate to attack the city, and the siege sergeants can directly set up a ladder to climb the city without crossing the forbidden ditch, and can launch an arrow counterattack against the defenders in the city at the location of the forbidden ditch, instead of being passively beaten as now.

At the thought of it, he was already excited, and after looking at the attacks in the direction of the various city heads, he quickly changed his mind, and immediately issued a new order, attacking the direction of the south gate with all his strength, and the attack on the east gate continued, but reduced the number of troops invested.

The Tang army at the east gate must be restrained and not allowed to reinforce the south gate, and at the same time order a sergeant to launch an attack in the direction of the north gate of Tongguan.

"Report to the marshal, the rebels in the direction of the north gate have also begun to attack the city!"

A sergeant quickly ran to Yang Xi's side on the tower of the city gate and reported the situation loudly.

Taking advantage of the height advantage of the city gate tower and a good field of vision, Yang Xi has been constantly observing the situation in the direction of each city gate, and he can see the battle situation in the direction of the three city gates without the report of the sergeant, but the specific details of the battle are not clear, especially in the direction of the north gate, which is the most dangerous terrain. After hearing the sergeant's report, he immediately inquired about the battle at the North Gate.

After understanding the battle situation in the direction of the north gate, Yang Xi's brows tightened.

Seeing that the attack in the direction of the east gate was still continuing, but the number of follow-up rebel attacks did not increase significantly, and there was a trend of decreasing, and there were not many sergeants swarming in the direction of the north gate, but a large number of rebel sergeants were going in the direction of the south gate, and the battle in the direction of the south gate showed no signs of easing, and he immediately understood what was going on.

The rebels were ready to intensify their assault in the direction of the South Gate, regardless of casualties.

The rebels were going to attack the south gate with all their might, even filling the forbidden ditch at the cost of casualties among the sergeants.

As soon as he thought of this, Yang Xi's eyes appeared in front of him the corpse of the Tang Army who had filled the ravine in the forbidden ditch, and the terrible scene after being burned by the fire, and he couldn't help but shudder slightly.

In later generations, even if there was a war, he would not adopt such a crowd tactic, regardless of the casualties of the soldiers, even if he used corpses to fill in, and did not give up with corpses piled up to the height of the city. Such a war is very cruel, a hundred times more cruel than the wars of later generations, and it tests the will of the people, especially the will of the commanders on both sides. Fortunately, Yang Xi's willpower is much firmer than that of ordinary people, although he has not seen the massacre of thousands of people, but he can calmly face death, large-scale death, without a mental breakdown.

Yang Xi believed that his judgment was correct, so he immediately ordered the guards at the north gate to not move, not to increase troops or withdraw troops, and to repel them as long as there was a rebel attack. It is impossible for the rebels in the direction of the north gate to launch a large-scale attack, and the scale of each siege is no more than two or three hundred people, and no matter how much it is not spread at all, with more than a thousand defenders on the head of the city, it is more than enough to deal with it. At the same time, he also sent a message to Ge Shuhan, Wang Sili, and Tian Liangqiu in the direction of the south gate, asking them to pay more attention to avoid the situation of failure when the rebels continued to attack the city on a large scale.

If the situation of the battle changed, he would lead his generals and a sergeant to reinforce the south gate and never let the rebels attack the city.

Yang Xi's proclamation was soon sent by the sergeant to Ge Shuhan, Wang Sili, and Tian Liangqiu.

Because the east gate is in the middle of the south gate and the north gate, standing on the east gate tower can roughly see the battle situation in the direction of the left and right city gates, but in the direction of the south gate, you can't see the situation of the north gate, and the battle situation in the direction of the east gate is also because of the obstruction of the cliff can not be seen clearly, Ge Shuhan, Wang Sili and Tian Liangqiu of the south gate do not know much about the battle situation of the east gate and the north gate, and only know the battle report of the east gate and the north gate.

The announcement from Yang Xi surprised Ge Shuhan and Wang Sili and other generals.

It seems that everything is possible, when the Tang army was defeated and fled back to Tongguan, the sergeants scrambled to flee for their lives, and almost filled the forbidden ditch, and the rebels are now attacking the city, and they are also preparing to fill in a section of the forbidden ditch with corpses to facilitate the siege. If the forbidden ditch is changed to a thoroughfare, even if it is only one section, then the defense of the city will be doubly difficult, and the rebels can use the height of the corpse stack to directly set up a ladder in the forbidden ditch to enter the city!

The great test is coming!
