Pang Tong's strategy was very abnormal, breaking the convention of the times. Pen? Interesting? Pavilion wWw. ｂiquge。 He divided the army into pieces, organized into a squad of 100 people, set off at night, and rushed to the Hanjiang Plain behind the Northern Xinjiang Army as fast as possible, so as to launch a counter-encirclement.

However, Pang Tong still underestimated the scouts of the Northern Frontier Army, he had just launched here, and Li Yi got the news there. However, Pang Tong's vicious strategy had many follow-ups, and he planned more than three assembly locations for each squad, echoing and transmitting messages from front to back. If a large force of the Northern Xinjiang Army pursues, it will disperse in a hurry, use mobility to evade, and then assemble separately to encircle and annihilate the enemy. If the Northern Xinjiang Army sends small troops to pursue them separately, it will be in the hands of the Yizhou Army. The Northern Frontier Army, which is not accustomed to water and soil, is definitely not the opponent of the Yizhou Army.

If the entire Northern Xinjiang Army retreats, it will be calculated. The Yizhou army will assemble at various designated locations, and under the leadership of Wu Yi, Liu Bi, Li Yan, the Yizhou generals, they will continue to ambush and sneak attack along the road.

The strength of the two sides is equal, and the original Northern Xinjiang Army absolutely crushed the Yizhou Army in terms of the quality of soldiers, but the Northern Xinjiang Army is all northerners, and the water and soil are not suitable for illness, which makes this Northern Xinjiang tiger become a sick cat, but it is helpless to Yizhou Army. Continuous sneak attacks, surprise attacks, and ambushes are bound to collapse and defeat the army.

Therefore, Pang Tong's serial strategy is very vicious and has many changes.

………………

The camp of the Northern Xinjiang Army, the big tent of the Chinese Army.

Li Yi got the scout's flying pigeon pass and was a little dumbfounded: "What? Liu Bei's troops were divided into thousands of units, interspersed with the Han River Plain? ”

Xu Maogong, Liu Bowen and Jia Xu's three major military divisions were also taken aback, they quickly saw through Pang Tong's fundamental intentions, Xu Maogong said: "Lord, Pang Tong's plan is to change the battlefield situation from two sides to counter-encirclement. If our army does not act, it will be surrounded in the hilly area of Yiling. ”

"Do you want to send troops to cut off Liu Beijun?" Li Yi frowned.

Liu Bowen shook his head and said, "Lord, the enemy is divided into teams of no hundreds, and the large forces of our army do not have enough time to break them one by one. If we also divide the soldiers into small groups to attack, most of them will not be able to adapt to the soil and soil, and the available troops will not be enough. ”

Jia Xu also said: "In the face of this situation, our army's response is nothing more than three possibilities: encirclement and suppression by large troops, meeting the enemy by small troops, or retreating by the whole army. ”

Speaking of this, he said as if he was beginning to talk to himself: "If a large force attacks, if the enemy formulates a preparatory plan, it is possible to assemble separately and encircle and annihilate our army." If our army meets the enemy with small forces, the enemy can be assembled or divided to meet the enemy. If our army retreats, it will take time. The enemy is already ahead of our army and will definitely set up an ambush. ”

Jia Xuxin said that Pang Tong, the ugly boy, is a vicious serial scheme, which is a clear bully of our army's refusal to adapt to the soil and water, and the combat effectiveness has been sharply reduced. is worthy of being a person that the lord has always valued, and he is really not inferior to himself and Mao Gong, Berwyn and others.

In fact, the most important link in Pang Tong's serial plan is the sharp reduction in the combat effectiveness of the Northern Xinjiang Army. It's like in another time and space, he tricked Cao Cao to connect the warships, didn't he also see that Cao's army was from the north and didn't practice water warfare? With Cao Cao's situation at that time, it was a last resort to connect the warships against the Jiangdong naval army. If you don't do this, it is even more unlikely that you will be the opponent of the Jiangdong Water Army.

The situation facing the Northern Xinjiang Army now is similar to that of Cao Cao at the beginning. Because of the lack of adaptation to water and soil, most of the Northern Xinjiang Army from the north of Xinjiang lost most of its combat effectiveness, and for the time being, it was not as high as the enemy's combat effectiveness, so it could only be defended with the advantage of the camp.

And Pang Tong saw the Achilles' heel of the Northern Xinjiang Army, that is, to make the Northern Xinjiang Army move, so that it had to go out of the camp to fight. Because if the Northern Xinjiang Army does not accept the recruitment and continues to hold on, it will be counter-surrounded by the Yizhou Army and cut off the grain route. In this way, the Northern Xinjiang Army will really be wiped out. As the saying goes, people are iron and rice are steel, and if you don't eat a meal, you will panic, let alone the 200,000 troops gathered together? In the original battle of Qin and Zhao Changping, the Zhao army was cut off by the Qin army, which led to the annihilation of the entire army.

In the case of being cut off by the Yizhou army, it was impossible for the Northern Xinjiang Army to continue to stay in the camp and hold on.

As for the amount of transportation from the waterway, it must be impossible for either Zhou Yu and Sun Quan in Jiangdong or Liu Biao who was trapped in Jiangling at this time to allow the Northern Xinjiang Navy to smoothly transport grain and grass from the waterway.

In the past, when he was in the north, the Northern Frontier Navy could bully the rest of the princes because there was nothing they could do about him. Who told those princes that they did not have regular naval armies?

But now the situation is different, whether it is Jiangdong or Liu Biao, they all have regular naval forces, and their strength is not weak. Maybe they can't resist the attack of the Northern Frontier Navy head-on, but harassment along the way, that's absolutely no problem. If the Northern Xinjiang Navy still wants to transport grain and grass to the inland army as before, then the Yangtze River route of several thousand miles will become a nightmare for the Northern Xinjiang Navy.

Li Yihao did not doubt that the Jiangdong Navy and Liu Biao's Navy would do this, because it was a matter of life and death for them. Once Li Yi is allowed to defeat Liu Bei, then the remaining three princes will really have no ability to resist Li Yi.

Therefore, from the very beginning, Li Yi never thought of transporting grain and grass from the Yangtze River waterway to Jingzhou.

Under the circumstance that the transportation of grain and grass by land and water has been cut off, Li Yi will suffer a loss if he takes any countermeasures.

Li Yi was silent, he didn't expect that he would encounter a day when he would not stand on his side when he fell into the right time and place.

Xu Maogong said with difficulty: "Lord, the whole army retreats, maybe there is still a chance." ”

"What do you mean maybe there's still a chance?" Li Yi was also a little anxious.

Xu Maogong didn't say anything else, but said: "The soldier's symptoms of unaccustomed to water and soil suddenly broke out, and they came too quickly. ”

Li Yi has naturally figured out that if there is no water and soil disadvantage, Pang Tong dares to divide his troops and dare to play anti-encirclement, and he will teach him to be a man in minutes. Because the personal quality of the soldiers of the Yizhou Army is not at the same level as the Northern Xinjiang Army, he dares to do so, he only needs to find a gap and slam the past, and he can defeat Liu Bei's Yizhou army in one battle.

Once the conspiracy is exposed, it won't do anything. But Yangmou is different, even if you find out, it is still difficult to crack.

Pang Tong's serial plan is now a conspiracy, that is, he is clearly bullying Li Yi, and now he does not dare to fight. Pang Tong was forced again, and he couldn't help but fight.

"The whole army retreats, step by step, and there may be a chance to bring a large army out." Xu Maogong said again.

What Xu Maogong said is also what Li Yi is thinking at the moment. In the case of all bad outcomes, the only option is to choose the one that is relatively not the worst.

Li Yi gritted his teeth and made a difficult decision, ordering an army of 180,000 to prepare to retreat.

………………

On the sixth day of June in the ninth year of Jian'an in the Eastern Han Dynasty (204 AD), there was a mountain outside Dangyang County.

Under the scorching sun of June, the earth seemed to be on fire.

Under the big tree, Pang Tong gently shook the feather fan, bringing a cool pleasure, and said with a smug smile: "Our army marches a hundred miles a day, and there is enough time to arrange everything. On the plain between Yiling and Dangyang, besiege Li Yi's soldiers and horses! ”

Liu Bei sat on the stone pier, and there was also a big pu fan in his hand, and he fanned it and said, "Why didn't Li Yi go to Jiangling to meet Guan Yu?" ”

Pang Tong grinned secretly, and said in his heart that he was really stupid, no wonder he had been chased by Li Yi all these years, and fled all the way to Yizhou in embarrassment, but he said in his mouth: "If Li Yi goes to Jiangling, all his soldiers and horses on the southern expedition will be surrounded by our army and Jingzhou soldiers under Jiangling City." If he can't break through, he will die without food. ”

"Makes sense!" Liu Bei wiped the sweat from his forehead and asked Pang Tongdao, "So from the perspective of the military advisor, what should we do next?" ”

Pang Tong shook his fan and said, "You can order generals such as Lei Tong and Meng Da to lead a small number of soldiers and horses to ambush all the way and take turns attacking Li Yi's retreating soldiers and horses. Li Yi must be defensive, and he does not ask Meng Da and other generals to break the enemy, but only needs to exhaust the Northern Xinjiang Army. Then he ordered General Zhou Cang, General Li Yan, General Liu Bi, General Wu Yi, and General Shamoke to lead the elite five roads to find a suitable place to wait for work and block Li Yi head-on. ”

"The Northern Xinjiang Army is not accustomed to the soil and water, and its body is already weak, and after being exhausted by Meng Da and other generals, it can be ordered to General Li Yan, General Zhou Cang, etc., to lead the elite division to go out in five ways, and the 100,000-strong army will tear apart the Northern Xinjiang Army, and the lord will lead the whole army to divide and surround it."

"Good, good, great!" Liu Bei said excitedly.

Liu Bei fanned his big pu violently, and ordered his guards to find Li Yan, Zhou Cang, Liu Xuan, Wu Yi and Shamoke, and ordered: "Quickly pass the order and carry out the operation according to the arrangement of the military division." ”

The five of them bowed down in unison and said, "Oh! ”

Liu Bi originally did not obey Liu Bei's orders, but after the Northern Xinjiang Army annihilated the army of his friend Ling Bao and killed Ling Bao, Liu Bi let go of his dissatisfaction with Liu Bei in his heart and cooperated with Liu Bei wholeheartedly, in order to defeat the Northern Xinjiang Army and avenge the death of his friend Ling Bao.

………………

In early June, on the Jianghan Plain, the heat was unbearable.

200,000 troops from the north marched on the Jianghan Plain against the sun. The sergeant was tired, but he had to fight hard, set up a defensive position, and slowly retreated to the north from end to end, step by step.

Every ten miles, Li Yi let the army rest and regain its vitality. It is estimated that it will only travel forty miles in one day, which is converted into the metric units of later generations, which is ten kilometers.

This is almost as slow as a turtle for the Northern Frontier Army, which originally traveled almost 100 miles a day. But even so, the soldiers of the Northern Xinjiang Army are still tired enough, because now they are not in a state one by one, and their bodies are almost hollowed out because of the lack of adaptation to water and soil.

Li Yi couldn't help but think of the time when he used Croton to deal with Zhai Yu when he was in the Northern Expedition to Ding Ling, I am afraid that Ding Ling's army at that time was similar to the current situation of the Northern Xinjiang Army. However, Ding Lingjun ate croton, but his army was because of the weather and regional environment.
