Sun Quan challenged Cao Jun to Cao Cao many times, but Cao Cao failed to hold on. Sun Quan personally sailed in a canoe and entered Caoshui Village from ruxu. As soon as Cao Cao saw it, he knew that Sun Quan was coming. It turned out that Sun Quan wanted to see the fighting in Cao Jun in person, and ordered the army to be on strict alert, and not to launch bows and arrows and crossbows. Sun Quan walked five or six miles before Cao Cao came back. When he left, he beat drums at Cao Jun. These were seen by Cao Cao and he sighed, "Born as Sun Zhongmou."

2, wai Wei to save Zhao

During the Warring States period, Wei besieged Handan, the capital of Zhao, and Zhao turned to its allies for help. Send Tian Ji to save Zhao. Tian Ji took advantage of Wei's elite troops in Zhao with the stratagem of military strategist Sun Bin, and the country was empty. He led his troops to attack Wei's girders. When Wei Jun retreated from Handan to rescue him, he took advantage of the danger of others and defeated Wei Jun in the siege of Guiling and Zhao. This battle is also called the Battle of Guiling.

3. Transfer from East to West

During the Eastern Han Dynasty, Ban Chao went to the Western Regions to unite with other countries in the Western Regions to fight against the Huns. In order to make it easier for countries in the western regions to fight against the Huns, we must first open up the north-south passage. Shache, located on the western edge of the desert, incited small neighboring countries to join the Huns and oppose the Han Dynasty. Ban Chao decided to pacify shache first. King shache went north to Qiuci for help, and King Qiuci led 50,000 troops to save shache. Ban Chao United with Khotan and other countries, with only 25,000 troops. Being outnumbered, it is difficult to beat them, so we must outsmart them.

Ban Chao was a diversion to confuse the enemy. He sent people to spread dissatisfaction with Ban Chao in the army, which made Qiuci invincible and showed signs of retreating. And especially let shache prisoners hear clearly. At dusk, Ban Chao ordered the Khotan army to retreat eastward. He led the troops to retreat to the west, seemingly flustered, and deliberately let the prisoners escape.

The prisoners fled back to shache camp and quickly reported the news that the Han army had hurriedly retreated. Wang Daxi of Qiuci, mistakenly thinking that Ban Chao was afraid of himself, hurriedly fled and wanted to take this opportunity to kill Ban Chao. He immediately ordered the soldiers to chase the fleeing enemy separately. He personally led ten thousand soldiers to the Western Expedition to pursue Ban Chao. Ban Chao had answers, and when night enveloped the desert, he retreated only ten miles, and the troops were hidden on the spot. King Qiuci, eager to win, led the pursuers to fly past Ban Chao's hiding place. Ban Chao immediately assembled troops, together with the pre-agreed Khotan East Road, and quickly returned to shache.

Ban Chao's troops fell from the sky, and shache was caught off guard and quickly disintegrated. King shache was in shock and could not escape, so he had to surrender. King Qiuci was aggressive and chased all night, but there was no sign of Ban Chao's army. He also heard reports that shache had been pacified and the casualties were slightly heavier. With the tide gone, he had to clean up the mess and return to Qiuci angrily.

Step 4: take a drastic measure

At the end of the Eastern Han Dynasty, warlords scuffled, and Yuan Shao of Hebei Province took advantage of the situation to rise. 199, Yuan Shao led a hundred thousand troops to attack Xuchang. At that time, Cao Cao was stationed in Guandu (now Zhongmou North, Henan Province), with only over 20,000 troops. The two armies confronted each other by the river. Yuan Shao relied on a large number of troops to send troops to attack the white horse. On the surface, Cao Cao gave up the white horse and ordered the main force to drive to Yanjin Ferry, poised to cross the river. Yuan Shao was afraid that someone would attack him behind him, so he quickly led the main force westward to stop Cao Jun from crossing the river. Who knows that after Cao Cao feinted, he suddenly sent elite troops back to attack Baima and killed Yan Liang, winning the first battle.

Due to the long-term stalemate between the two armies, the supply of grain and grass has become the key. Yuan Shao mobilized more than 10,000 wagons of food and grass from Hebei and assembled in Wu Chao, 40 miles north of the base camp. Because I didn't take little Cao Cao seriously, I didn't send heavy troops. Cao Cao found that the Wu dynasty was not heavily defended, so he decided to sneak up on the Wu dynasty and cut off its supplies. He personally led 5,000 elite soldiers, scurried with medals under the banner of Yuan Shao, and attacked the Wu Dynasty at night. Yuan Jun of the Wu Dynasty has not discovered the truth, and Cao Jun has surrounded the granary. A fire was lit and suddenly there was smoke everywhere.

Cao Jun took advantage of this opportunity to destroy Yuan Jun, the grain depot administrator. The food and grass of10,000 wagons in Yuan Jun suddenly turned to ashes. Yuan Shao's army was disturbed, supplies were cut off and morale was floating. Yuan Shao had no idea at the moment. At this time, Cao Cao launched a full-scale attack, Yuan Jun soldiers have lost their fighting capacity, and hundreds of troops fled everywhere. After Yuan Jun was defeated, Yuan Shao led 800 troops to deus ex, Qin Bing, and returned to Hebei, never recovered.

5. Pay attention to the fire on the other side

At the end of the Eastern Han Dynasty, Yuan Shaobing was defeated and killed, and several sons fought for power and profit. Cao Cao decided to defeat the Yuan brothers. Yuan Shang and Yuan brothers defected to Wuhuan, Cao Cao sent troops to defeat Wuhuan, and Yuan brothers defected to Liaodong Prefecture Gongsun Kang. Cao Cao's generals advised Cao Cao to make every effort to pacify Liaodong and capture Er Yuan alive. Cao Cao laughed and said, "Don't move, Gongsun Kang will send Er Yuan's head to the door." . So he ordered the troops to move back to Xuchang and wait and see the situation in Liaodong.

Gongsun Kang was suspicious when he heard that Er Yuan had defected. Yuan and his son have always had the ambition to seize Liaodong. Now, Yuan's defeat is like a lost dog with nowhere to live. Going to Liaodong is a last resort. If Gongsun Kang takes Er Yuan in, there will be future trouble. Moreover, taking Eryuan in will certainly offend Cao Cao, who is fierce. But he thought that if Cao Cao attacked Liaodong, he would take Er Yuan in and fight Cao Cao.

When he found that Cao Cao had turned back to Xuchang and had no intention of attacking Liaodong, he thought it was harmful to take Eryuan in. So he laid an ambush, summoned Er Yuan, captured him in one fell swoop, beheaded his head, and sent someone to see Cao. Cao Cao smiled and said to the generals, "Gongsun Kang has always been afraid that Yuan would annex him. If Yuan comes to the door, he will get suspicious. If we are eager to fight, it will lead to their common resistance. If we retreat, they will definitely kill each other. " Look at the results, as I expected! "
