For Zhu Wei, Luoyang is definitely a good battlefield that is easy to defend and difficult to attack.

Of course, Zhu Wei is by no means the type who will not fight back just after being beaten, so Zhu Wei's Luoyang defensive battle this time has set a strategic arrangement to defend Yuan Shao and wait for an opportunity to counterattack Cao Cao.

It's just against Cao Cao's counterattack, so it still depends on the effect of the edict.

For a while, after Cao Cao and Yuan Shao issued a letter to fight against Zhu Wei, the situation in the world became a little tense again, and the strongest tripartite forces today were finally about to go to war.

Everyone knows that after this battle, the situation in this Han world will definitely change significantly.

Probably in June of 199 AD, Cao Cao personally led 50,000 troops, and swore to conquer Zhu Wei in Xudu.

In this way, Cao Cao is really ready to go to the Yellow River to unite with Yuan Shao's army, and then attack Luoyang in the direction of Tiger Pass.

And Yuan Shao also responded to Cao Cao's dispatch of troops, and sent Yan Liang as the main general's vanguard army of 20,000 from Hanoi to Mengjin Pass of the Yellow River, seemingly preparing to cross the Yellow River here to threaten the north of Luoyang.

In addition, Yuan Shao sent 20,000 cavalry forward troops with Wen Chou as the main general, crossed the Yellow River through the Yanjin Ferry of the Yellow River, and really joined Cao Cao's army in the Guandu area, and then marched together in the direction of Hugao Pass.

As for Yuan Shao himself, it seems that he made an excuse and did not personally participate in the war, but in order to prevent the army led by Wen Chou from being used as cannon fodder by Cao Cao, Yuan Shao sent Fu Zhi as the governor of the supervising army and Zhang He as the deputy general in Wen Chou's soldiers and horses.

Now among Yuan Shao's military advisors and strategists, that is, Fu Zhu and Guo Tu are most valued by Yuan Shao, and the two of them plus a Chun Yuqiong, who often serves as the governor under Yuan Shao's account, and then Yan Liang, Wen Chou, Zhang He, these generals.

As for Tian Feng, Xianping, Feng Ji, and Xu You, that is, the members of the strategist group around Yuan Shao, except for the occasional temporary assignments, they are generally idle.

Now Yuan Shao trusts Yan Liang's ability to lead the army alone, or Yan Liang is on the side of Mengjin Pass on the Yellow River, Yuan Shao did not give too many military requirements, so it is enough to send Yan Liang as a general.

On Wen Chou's side, Yuan Shao was still worried that Wen Chou would be sold by Cao Cao and count the money, so he sent such a wise man and celebrity as the governor of the prison army, but he was not afraid of being played by Cao Cao.

Of course, although Yuan Shao sent 40,000 soldiers and horses to conquer Zhu Wei with Cao Cao, he obviously still retained a lot of strength.

But in any case, the war between Cao Cao and Yuan Shao's combined forces against Zhu Wei finally broke out, and after Zhu Wei discovered the movements of Cao Cao and Yuan Shao's armies, he sent Zhou Tai and Jiang Qin of Xionglu's camp to lead 15,000 troops to Mengjin, Xiaopingjin and other Yellow River crossings in the north of Luoyang to resist Yan Liang's army.

Later, he asked Pang Yan to take the Xionglu battalion commander Shi Yizhi, and the generals Xing Daorong, Hao Meng, and Cheng Lian to lead the 20,000 troops of the Xionglu battalion, plus the 15,000 troops on the left side of the Chinese army under Zhuge Liang's command, to rush to the Tiger Prison Pass defense to meet the main force of the combined forces of Cao Cao and Yuan Shao.

Zhu Wei asked Zhuge Liang to go to the Tiger Prison Pass, but also to prevent Pang Yan from being deceived by Cao Cao's strategy, although Zhuge Liang has not fully grown up now, but he is born with a hundred intelligence, and he should still be able to see through many conspiracies.

Previously, Zhu Wei had also sent Ling Cao, the deputy general of the Xionglu battalion, with Lei Bo and Chen Lan, to lead the 15,000 troops of the Xionglu battalion to garrison Yuyuan Pass, and sent Sun Quan, Sun Shangxiang, and Sun Jing to garrison the area of Dagu Pass and Guangcheng Pass with about 15,000 troops on the right side of the Chinese military camp.

Although Cao Cao did not use troops from this side now, Zhu Wei did not take them back for the time being, after all, Zhu Wei's troops left in Luoyang still have 3,000 white feather guards from the Chinese army's personal guard battalion, 8,000 sword and shield guards, and the remaining nearly 30,000 troops of the Chinese army, which is enough to deal with all kinds of possible changes.

In fact, if there is a crisis, the garrisons at Yuyuan Pass, Dagu Pass, and Guangcheng Pass can also be reduced and the troops can be transferred for other use.

However, judging from the current battle situation, the Tiger Prison Pass where Pang Yan and Zhuge Liang are located is only afraid that it will become the main battlefield of this war, and as for the Yellow River crossing on the side of Mengjin and Xiaopingjin, Yan Liang may not be able to find the opportunity to cross the river.

Sure enough, with the passage of time, about in mid-June of 199 AD, the Yan Liang troops sent by Yuan Shao temporarily stopped five miles away from the camp on the north bank of the Yellow River, where the Mengjin Pass was located, but the attack on the Mengjin Pass was obviously not in a hurry.

And before the Tiger Prison Pass, Cao Cao and Yuan Shao's more than 70,000 allied troops were finally killed.

As mentioned above, the Tiger Prison Pass is also known as the Bishui Pass, or it can also be called the Revolving Gate Pass, and the construction of the Guancheng is also a military fortress-type military town formed by the help of the natural mountain pass terrain according to the surrounding mountains and mountains, thus cutting off the only official road leading to Luoyang in the Central Plains states and counties.

In fact, the Tiger Prison Pass was officially built in the Qin Dynasty, and in the earlier Western Zhou Dynasty, King Mu of Zhou once raised the fierce warriors in captivity at the Tiger Prison Pass to capture the fierce tigers that were sacrificed, so this pass town will be named the Tiger Prison.

At the time of Emperor Ling of the Eastern Han Dynasty, this Tiger Prison Pass was renamed the Spiral Gate Pass from the official point of view, so the current Tiger Prison Pass should indeed be called the Rotary Gate Pass, but it is still customary to call it the Tiger Prison Pass.

Although there was no romance of the Three Heroes against Lu Bu before this tiger prison, it also had the momentum of being a man and a man.

Although Zhu Wei did not strengthen the city wall in the Tiger Prison Pass before, the wall of the Tiger Prison Pass is five or six stories high according to the mountains on both sides, which is comparable to the height of the city wall of a large city.

At the same time, because the Tiger Prison Pass is built in the mountain pass within the mountain range, the mountains on both sides of the Tiger Prison Pass are also steep and difficult to climb the cliff terrain, so it is impossible for the enemy troops attacking the Tiger Prison Pass to climb the mountains on both sides to attack or break through the Tiger Prison Pass by climbing the mountains, and can only launch a strong attack on the Tiger Prison Pass from the front.

In addition, the location of the Tiger Prison Pass is a hillside, so the defenders not only have the condescending momentum of the city wall, but also the condescending advantage of the entire mountain situation on the Tiger Prison Pass.

About 500 steps in front of the Tiger Prison Pass is a relatively narrow mountain valley road, and there are mountains on both sides to spread out, so that the foreign enemy attacking the Tiger Prison Pass can only spread out a thousand troops at most in front of the Tiger Prison Pass, which increases the difficulty of attacking the Tiger Prison Pass.

Of course, it is impossible for this kind of pass-type military town fortress to be surrounded by attacking enemy troops, so the soldiers and horses guarding the Tiger Prison Pass do not have to worry about the enemy's siege tactics, and there is no need to think that the defenders in the Tiger Prison Pass will not attack themselves because of the lack of water and food.

Originally, three or four thousand troops were stationed on the side of Tiger Pass, which was actually enough to resist the attack of tens of thousands of enemy troops, but now Zhu Wei has put nearly 40,000 troops stationed here, and he can fight with the more than 70,000 Cao Cao and Yuan Shao coalition troops who attacked......
