As the so-called soldiers and horses have not moved, grain and grass go first. Especially in the late Han Dynasty, the transportation capacity was extremely backward, and the transfer of military resources such as grain, grass, and baggage was definitely the top priority for marching and fighting.

Logistics has always been the soft underbelly of the vast majority of the military. I think that when Emperor Wu of the Han Dynasty went on a northern expedition to the Xiongnu, there were hundreds of thousands of migrant workers alone. In particular, the main force of Youzhou is dominated by cavalry, and the consumption of grain and grass can be imagined.

If there is a person who is good at this, it will only be more conducive to the army to go on the expedition with the appropriate tools. Of course, Youzhou now has these two items, and good steel should be used on good knives, which is originally the employment strategy that Huo Yu, the shopkeeper has always pursued.

At the beginning of May, an army of 100,000 led by Huo Yu appeared in Liyang on the north bank of the Yellow River. The long-awaited war is about to break out, and this time Huo Yu is going south with all his might, and his determination can be seen.

The 100,000-strong army rested in Liyang for ten days, and then marched south to Yanjin and approached Guandu. When the news spread, the world was boiling, and the most anxious person was none other than Cao Cao.

Although he had long been prepared to shrink his defenses, when the great enemy came, Cao Cao urgently summoned a group of henchmen to discuss countermeasures. The good point is the unity of opinion, that is, to fight to the death with Huo Yu, and no one advocates surrender at all.

The fact that his subordinates were able to have such determination also shows that Cao Cao's ideological work has been done very sufficiently. Since there is a consensus of opinion, the next step is to discuss how to fight this battle.

"Lord, although Huo Yu has an army of 100,000, at least 30,000 are newly recruited soldiers. Therefore, the combat effectiveness is strong and weak, and we can only mobilize 50,000 troops to avoid its edge. Xun Yu, as Cao Cao's chief strategist, said bluntly.

Although there was already a gap between the two, Xun Yu's words made Cheng Yu and other civil and military generals also nod their heads, and they thought it was true.

Although Cao Hong, Xiahoudun, Xiahou Yuan and other generals were a little dissatisfied with the defensive battle, Xun Yu was extremely prestigious in Cao's army, but he did not question it.

"If you say it makes sense!" Cao Cao nodded and motioned for him to continue.

"The art of war is full of vigor, then decline, and exhaustion. At this time, if there is a war, it is a taboo for soldiers. Only by weakening its momentum can it find an opportunity to break the enemy. “

"Our army is inferior to Huo Yu, so we must not go head-to-head with the Youzhou army when it is strong. Yu believes that our army should make rational use of the terrain and hold on to the danger. ”

"As long as you can block the early onslaught of the Youzhou army, over time, the morale of the army will naturally decline, so that there will be a chance to break the enemy."

Xun Yu said what he thought in one breath, and Cao Cao's gloomy face finally showed a smile.

"If what Wen said is very much in line with my intentions, Ben Hou also has this intention. Earlier, Zixiao led an army of 20,000 to build a defensive line in Guandu, and Ben Hou wanted to block Huo Yu from going south in Guandu, looking for an opportunity to break the enemy depending on the situation! ”

After Cao Cao finished speaking, he looked around, but did not find anyone to object, so Cao Cao drew his sword and rose.

"The generals will listen to the order in front of the soldiers and horses of the headquarters, and if Wen takes care of the affairs of grain, grass and military affairs, we will fight to the death with the Youzhou army in Guandu."

"No!" Everyone agreed in unison, and they were heroic.

After the military discussion, the generals prepared to go, but Cao Cao left Xun Yu and Cheng Yu behind.

"The lord is worried about Xuchang?"

Cheng Yu knew Cao Cao very well and knew what Cao Cao was most concerned about at the moment.

"Although this battle is dangerous and unpredictable, the Youzhou army is strong, Huo Yu is very cunning, although he is fighting in Guandu head-on, it is difficult to guarantee that there will be no moths behind him." Cao Cao said worriedly.

"If Huang Zhong captures Xuchang when the war is tight, our army will be in danger." Cao Cao nodded, this is a consensus that has been reached a long time ago, needless to say.

"My lord, now that Cao, Liu, and Sun are allied, when the lips are dead and the teeth are cold, the pros and cons must be clarified to the other two, Liu Biao needs to send troops north to contain Huangzhong in Yuzhou, and Sun Quan needs to attack Xuzhou." Cheng Yu opened his mouth to remind.

"The envoy has been sent for some time, but I don't know how things will develop, so I will prepare for the worst." Cao Cao pondered for a while and said in a deep voice.

Xun Yu and Cheng Yu nodded lightly, both with a trace of worry in their hearts. The two glanced at each other, and although they didn't speak, they understood each other's thoughts at the same time.

Whether it is Cao Cao, Xun Yu, or Cheng Yu, the three of them all understand that this battle is really unpredictable.

If it's just a head-to-head matchup, it's not too much of a problem. But if you add Yuzhou eyeing Huang Zhong, the situation is really not optimistic, and Cao Cao doesn't even want to think about the final result.

"Lord, Xuchang has Zhongda defense, and it must be worry-free!" Xun Yu opened his mouth, finally finding a little comfort.

Cao Cao paused for a moment, then nodded quickly. In this situation, only dead horses are treated as live horse doctors.

Three days later, Cao Cao, who was all ready, personally led his army to Guandu to prepare to meet the 100,000 Youzhou army led by Huo Yu.

Of these 30,000 troops, Cao Ren had already led 20,000 troops to Guandu to garrison them long ago. Now that the army has been mobilized, Chen Liu has only 2,000 old and weak soldiers left.

However, not long after Cao Cao sent his troops, shocking news came from Jingzhou. In April, just as Huo Yu raised his troops to the south, Lu Bu sent troops to contain Liu Biao according to the agreement with Huo Yu, but because of the full cooperation of the Dark Yu Guard, Lu Bu hid under Liu Biao's nose.

Lu Bu's trick made the Jingzhou army advance northward with his head covered and annihilated. Liu Biao, who had originally planned to give priority to capturing Wancheng, only now did he know that Huo Yu and Lu Bu had already formed an alliance.

Why is this judgment? It's just because the bows and arrows used by Lu Bu's Bingzhou army are all produced in Youzhou. When the news reached Xiangyang, Liu Biao was immediately shocked and hurriedly ordered the army to retreat.

This move is in Lu Bu's arms, if he has a hard encounter with Liu Biao, Lu Bu is naturally not afraid, but how long can this little force in his hands be consumed?

In Xiangyang City, Liu Biao convened a group of civil and military personnel to discuss urgently, and Lu Bu, who originally thought that the end of the crossbow, had formed an alliance with Huo Yu.

"Lord, Lu Bu has formed an alliance with Huo Yu, and the last general has not received any news before." Cai Mao, who rushed back in the starry night, spread her hands helplessly.

"Alas, judging from the current situation, Lu Bu's actions seem to be guarding against our army, and it is obvious that he has already reached some kind of agreement with Huo Yu, how can this be good?"

Silence, there was silence in the meeting hall, not to mention anything else, in a frontal field battle with Lu Bu, the generals of Jingzhou did not have the courage yet, besides, even if they still won, they still have the strength to capture Yuzhou?

"Lord, the only way to do this now is to give priority to eliminating Lu Bu! As for Yuzhou, we are afraid that we are powerless, but fortunately, Sun Quan in Jiangdong is strong, and I believe that good news will come from the direction of Xuzhou. Kuai Liang looked at Liu Biao's gloomy face and got up to persuade him, who made the Jingzhou soldiers the weakest.

In fact, it is not true, if Jingzhou can have a general, I believe that it will be easy to defeat Lu Bu. It's a pity that Liu Biao's indecisive character determines that he will not be able to become a big weapon in the end!
