The attack of the Wu army did not stop all night, but the effect of the offensive was unsatisfactory, the attack during the day Wu army can occasionally break through the defense line in a small area, rush to the head of the city, but all night, there is no Wu soldier can complete the breakthrough, most of the Wu soldiers were shot dead or injured in the process of climbing, from the perspective of the whole night of fighting, the Wu army is more like to send people to the head.

This is first of all related to the difficulty of attacking the city at night, for the defenders, there is basically no difference between day and night, and even if there are some differences, it is very small, and it does not affect the defense effect at all.

But the siege was different, it was pitch black, the eyes could not see, and there were not even some obstacles and traps on the way, and many people lost their lives because of this.

In fact, if you want to attack, you must light a torch to illuminate, and after the lighting, it is equivalent to exposing your position to the Wei army, and the Wei archers hiding in the dark can completely release cold arrows to sneak attack, and the Wu soldiers are holding torches to move forward, which is equivalent to erecting a live target for others.

The second is that the morale of the Wu army has plummeted, and there is no longer as high morale as when they attacked before, and the Danyang soldiers are brave and brave, but they are also people, not machines, and there are always times when they are tired and weak.

Zhuge Ke was stubborn and self-serving, disregarding military strength, and tried in vain to build a road of revenge with the flesh and blood of Wu soldiers, but under the strong Anfeng City, no matter how many corpses of the Wu army were piled up, it was in vain.

Compared with the sluggishness of the Wu army, the defense of the Zhengnan Army was methodical and leaky, and the tactical strategy of "three shifts" arranged by Cao Liang made the Zhengnan Army not tired at all, and they fought in full state all night, and the Wu army could not bargain in front of them.

At the beginning, after Anfengdu fell into the siege, the battle of the southern army was particularly hard, in order to break through, they fought desperately, and in the end they suffered half of the casualties, and many familiar comrades in the robe Ze were not able to get out of that mountain forest in the end.

All the survivors had a heart of revenge, and it was their greatest long-cherished wish to avenge their dead brothers.

Of course, this is only the wish in their hearts, the battle of An Fengdu, the southern army suffered heavy losses, and it seems that it has become very distant to take revenge.

But they didn't expect that after only two days, they would have the opportunity to confront the Wu people again, and they relied on the city to overlook the opponent in a condescending posture.

This battle of the southern army was fought heartily, when they pulled the bowstring, they all carried a sense of revenge, and the screams of the Wu soldiers before the temporary sound seemed to them to be like the most beautiful rhythm, which could comfort the souls of those comrades who died in battle.

Cao Liang only stayed up in the first half of the night, and in the second half of the night, he was also sleepy, after all, during the day, Cao Liang fought side by side with Wang Ji, and he never rested at all.

However, the fighting state of the southern army made him very relieved, even if Cao Liang went to sleep, he could sleep very steadily, as long as he followed this style of play, no matter how much the Wu army tossed, it would be impossible to break through Anfeng City.

When leaving the city, Cao Liang specially told Ren Lan to abide by the three-shift battle plan, pouring every two or three hours, so that the Wei soldiers had enough time to rest and recuperate, and always maintain sufficient physical strength and high morale.

This is very important, because the Wu army's offensive cannot be just one day and one night, and in the next few days or even longer, the Wu army's attack will be continuous, and the Wei army must be prepared for a long period of battle.

Cao Liang remembered that the longest defensive battle in history was the Diaoyu City in the Southern Song Dynasty, which held on for 36 years until the fall of the Southern Song Dynasty, and this city had not fallen, which can be called a miracle in the history of war.

However, it is impossible for the battle of Anfeng to last so long, not to mention that there are still Sima Yi's reinforcements in Huaibei, even if he is a hundred reluctant, it is impossible to stay still, and under the pressure of the imperial court, Sima Yi will eventually cross the Huai River and attack Huainan.

Even if Sima Yi can't count on it, Cao Liang doesn't believe that the Wu army's hundreds of thousands of troops can hold out for a long time, after all, the huge logistics supplies required for the operation are not something that the Wu army can withstand for a long time, the larger the size of the army, the smaller the scope and time of the operation, as long as An Fengcheng can hold on for a period of time, the Wu army will not be able to resist repeatedly, and will eventually retreat on its own.

The war is fought in logistics, grain and grass, ordnance supply, these are the foundation of an army, Sun Quan in order to plan this attack, must have been raising for a long time, with the national strength of Wu State, there is no problem to support the combat supply of 200,000 troops in a short time, but after a long time, I am afraid it is really unbearable.

Anfeng City is different, generally in a border county like Anfeng, the grain and grass reserves are extremely sufficient, at least more than half a year's grain stockpile, even if more than 15,000 people are added to the southern army, Anfeng City guarantees that the supply of grain and grass for two or three months is no pressure.

Just such a long time was enough to drag down the Wu army.

Cao Liang left the city with the first batch of Zhengnan troops who landed in the city, and they were replaced by Wei soldiers from the Xiaocai battalion and the guerrilla battalion.

The city battle, naturally can not ride a horse, the Xiao cavalry battalion at this time abandoned the horse to the city, the combat effectiveness is naturally not comparable, but the fighting spirit of the Xiao cavalry battalion did not slack off because of the loss of the war horse, but the morale was high, under the leadership of Wen Qin, the fish penetrated the city and took over the defense.

With Wen Qin here, Cao Liang is naturally more relieved, Wen Qin has always been known for his calm and generous, and he is very good at commanding the army, and it is better for him to assist Ren Lan to guard the city.

Cao Liang said a few words to Wen Qin, Wen Qin immediately nodded yes, and Cao Liang left with confidence.

Returning to the garrison of the Southern Army, Cao Liang slept peacefully, and he really slept very soundly, even if the sound of killing in the city shook the sky, it did not affect his good dreams.

When Cao Liang woke up in the early morning, he found that the deafening shouting and killing sound at the head of the city had disappeared and became silent.

Cao Liang hurriedly got up and rushed to the city, halfway up, he met Wang Ji who had rested for a night, Wang Ji's spirit had obviously recovered a lot, and his face was radiant, he also heard the news of the city before rushing over, the two simply said hello, hurried away, and boarded the city together.
