How did Cao Cao defeat Yuan Shao?

Yuan Shao successively annexed Gongsun Zan and Sizhou, led an army of more than 65,438+10,000 people, and will March to attack Xudu. Cao Cao's generals thought it was irresistible. Cao Cao said: "I know Yuan Shao's character, which is ambitious but wise, stern and timid, jealous and mean, lacking in prestige, thoughtful and hesitant, but many advisers are not used by him. Although many soldiers are not well-directed, poorly planned, the generals are arrogant and the decrees are not unified, although they are vast in territory and abundant in food, they are just my dedication." In autumn and August, Cao Cao invaded Liyang, sent to Qingzhou to attack Qi, Beihai and Dongan, and stayed by the Yellow River. In September, Cao Cao returned to Xudu and divided some troops to guard Guandu. In winter 65438+ 10, Zhang Xiu led the troops to surrender. In February 65438, Cao Cao was stationed in Guandu.

In February of the following year, Yuan Shaopa sent Guo Tu, Chunyu Qiong and Yan Liang to attack the Eastern Prefecture of Ada in Baima. Yuan Shaoling led the troops to Liyang, ready to cross the Yellow River. In summer and April, Cao Cao went north to save Ada. Xun You persuaded Cao Cao to say, "Now we are resisting too few troops. Only by dispersing the enemy can we win. In Yanjin, pretend to be ready to cross the Yellow River and March to their rear. Yuan Shao will certainly go west to meet the enemy, and then send light troops to attack Baima, so that Yan Liang can be caught unprepared. " Cao Cao listened to Xun You's plan. When Yuan Shao heard that Cao Jun had crossed the Yellow River, he immediately sent troops to the west to face Cao Jun ... Cao Cao led his army straight for the white horse, and there was still more than 10. Yan Liang was frightened and came to fight. Cao Cao sent Zhang Liao and Guan Yu as pioneers, first defeated the enemy, beheaded Yan Liang, finally lifted the siege of the White Horse, moved the white horse people, and traveled westward along the Yellow River. Yuan Shao then crossed the Yellow River to pursue Cao Cao's troops. After catching up with the south of Yanjin, Cao Cao ordered the army to camp under the western hillside and sent people to the camp to check on the enemy. The report said: "There are about 6,000 cavalry." After a while, he reported: "the cavalry is increasing gradually, and there are too many infantry to count." Cao Cao said, "There is no need to report again." He ordered the cavalry to put down their saddles and let the horses go. At this time, the trench of the white horse defenders has already hit the road. The generals thought that the enemy had more cavalry, so they might as well go back and guard the barracks. Xun You said, "This is used to lure the enemy into the bait. Why are you leaving here? " Yuan Shao's cavalry generals, Wen Chou and Liu Bei, led about 6,000 cavalry to arrive successively. The generals also said, "You can get on the horse." Cao Cao said, "That's enough." So everyone got on the horse. At that time, there were less than 600 cavalry, so they attacked, defeated the enemy and beheaded Wen Chou. Yan Liang and Wen Chou are both famous players under Yuan Shao. After two battles, they were captured and killed. Yuan Shao's army was greatly shocked, and Cao Cao returned to the official entrance. Yuan Shao marched to defend Wu Yang. Guan Yu fled back to Liu Bei.

In August, Yuan Shao was connected with the camp, and gradually moved forward, and was stationed with his back against the sand dunes, stretching for dozens of miles from east to west. Cao Cao also divided his troops and camped against the enemy, and the situation was unfavorable. At that time, Cao Cao's troops were less than 65,438+million, and the wounded accounted for 23/ 10. Yuan Shao's army advanced into Guandu, heaped up heaped-up mountains and dug tunnels. Cao Cao is still piling up dirt mountains in the camp, digging tunnels and confronting the enemy. Yuan Yi's arrow shot into Cao Barracks, and it rained down, so people walking around had to be blocked with shields. Everyone is very scared. At this time, Cao Cao was short of food, so he wrote to Yu Xun to discuss withdrawing troops from Xudu. Yu Xun wrote back: "Yuan Shao's troops are all gathered in Guandu, ready to fight with you. You use the weakest force against the strongest enemy. If you can't subdue him, you will be hunted by the enemy. This is a great turning point for the world. Besides, Yuan Shao is just an ordinary hero, who can gather talents but can't use them. With your wise SHEN WOO, with the life of the son of heaven, what else can't be done successfully? " Zuo Zongtang listened to Yu Xun's suggestion.

When Yuan Shao's thousands of grain wagons arrived, Cao Cao adopted Xun You's plan, sent Huang Xu and Shi Huan to intercept them, defeated Yuan Jun and completely burned Yuan Shao's grain wagons. Cao Cao and Yuan Shao were at loggerheads for several months. Although every battle is to kill the enemy, the food for serenade is used up and the soldiers are tired. Cao Cao said to the grain carrier, "15 days, I will defeat Yuan Shao for you, and I won't let you work hard anymore." /kloc-in the winter of 0/0, Yuan Shao sent a car to transport grain, and a convoy of more than 0/0000 soldiers led by five people, including Chun Yuqiong, camped 40 miles north of Yuan Shao's military camp. Yuan Shao's counselor Xu You is very greedy. Yuan Shao couldn't satisfy him, so he came to Cao Cao to persuade him to attack Chunyu Qiong and others. People around Cao Cao doubt him. Xun You and Jia Xu persuaded Cao Cao to adopt it. Cao Cao left Cao Hong to defend himself, and led 5000 infantry and cavalry at night, and arrived at dawn. Chunyu Qiong and others saw Cao Cao and serenade and went out to the camp gate. Cao Cao quickly attacked Chunyu Qiong, and Chunyu Qiong retreated to the barracks, so he attacked the barracks in Chunyu Qiong. Yuan Shao sent cavalry to save Chunyu Qiong. Someone around Cao Cao said, "The enemy cavalry is approaching, asking for an adventurous resistance." Cao Cao was angry and said, "The enemy will report behind his back!" " Soldiers fought to the death, defeated Chunyu Qiong and others, and beheaded them all. When Yuan Shaogang heard that Cao Cao had attacked Chunyu Qiong, he said to his eldest son, Yuan Tan, "When he attacked Chunyu Qiong and others, I went to capture his barracks and he had no place to live!" So he sent Zhang He and Gao Lan to attack Cao Hong. Zhang He and others heard of the fall of Chunyu Qiong and came to surrender. Yuan Shao's army was defeated, and Yuan Shao and Yuan Tan abandoned the army and fled, crossing the Yellow River. Cao Jun caught up with them, took all their trenches, charts, documents and treasures, and took their priesthood. In the letters that Cao Cao captured Yuan Shao, Xu Duhe's people had correspondence with Yuan Shao, and Cao Cao burned them all. Many cities and counties in Jizhou surrendered voluntarily.

In the summer of April, 2006, Cao Cao inspected the army by the Yellow River, attacked Yuan Shao's army in Cangting and defeated it. When Yuan Shao came back, he gathered the skirmishers and put down the rebellion against the county. In September, Cao Cao returned to Xudu.

Since the defeat of the army, Yuan Shao became ill and vomited blood, and died in the summer of May. Yuan Shang, the youngest son, took the post, and Yuan Tan claimed to be a general riding a bicycle and was stationed in Liyang. In autumn and September, Cao Cao conquested them and fought fiercely. Yuan Tan and Yuan Shang repeatedly lost and retreated, and held on to Liyang.
