The War to Resist U.S. Aggression and Aid Korea can be said to be a great victory in Chinese history. Through this battle, the Chinese nation successfully shattered the US imperialist ambition and won valuable peace for the New China.
Nowadays, there is no overwhelming power gap between China and the United States, but more than 70 years ago, the gap in strength between the United States and China seemed to be an insurmountable gap. Therefore, the victory of the War to Resist U.S. Aggression and Aid Korea is even a miracle in the eyes of many people.
But there are not so many "miracles" in this world. On the Korean battlefield, every victory achieved is supported by rigorous tactics, and every inch of land captured is replaced by heroic soldiers with flesh and blood. Under the leadership of Commander-in-Chief Peng, the Volunteer Army relied on the amazing tactics to write down "impossible" on the Korean battlefield. However, he was not careful to fall into a trap. The 100,000 troops left the home team and were surrounded by " United Nations Army ". Peng Dehuai had no choice but to seek help from the central government, and Chairman Mao only used the eight-character strategy to repel the enemy.
phased victory
Originally, when the United States set foot on the Korean battlefield, it planned to make a quick decision. After quickly resolving the North Korean issue, the United States would aim its planes and cannons at China's territory, in an attempt to burn the war again to this country that had just left the war.
But what they did not expect was that since the Volunteer Army participated in the Korean War in in 1950, the US military lost more than wins on the Korean battlefield, and the morale of the entire army was greatly reduced, and the Volunteer Army also achieved phased victory.

The US military did not take the Volunteer Army seriously at all. This team cannot produce anti-aircraft guns, large-caliber shells, and even sufficient bullets, food and clothing are difficult to provide. Therefore, when the Volunteer Army lied to them that they were just here to defend the hydropower station, the US military believed it.
I'm afraid at that time, the US military would never understand no matter how hard it was to think about it. How dare such a unit with a huge gap in its hard power against it on its position? But after the real fight, the US military had another problem that could not be understood: Why can't it defeat this unit?
On October 25, 1950, the US military and the Volunteer Army fought on the North Korea-China border for the first time. In the first battle of , the Volunteer Army invested a large amount of troops. In just over a dozen days, it drove the US military from the Yalu River to the south of Qingchuan River, annihilated more than 15,000 enemies, shattering the US military's dream of occupying North Korea before Thanksgiving.

November 7, two days after the end of the first battle, the volunteer army once again took the initiative to attack the US military. The volunteer army was divided into two routes, east and west, and launched an attack on the enemy at the same time. The US military seemed in a hurry in the face of the sudden double-team attack and had to retreat continuously. The volunteer army and the Korean People's Army drove the US military to the south of "38th Line ".
Although this battle caused the "United Nations Army" commanded by the US to directly lose more than 36,000 troops, the US military still did not regard the Volunteer Army as an opponent at this time. They believed that the Volunteer Army was just here to defend China's borders, which made the US military even fantasize about occupying the entire North Korea before Christmas.
However, in the later battles, the US military gradually realized the seriousness of the matter. They were defeated by the volunteers and urgently needed time to adjust and rest, but they knew in their hearts that the volunteers would not give them a chance to breathe on the battlefield.

So the United States proposed to negotiate with China, attempting to delay time and give the US military on the Korean battlefield a chance to turn things around.
But how could such a cleverness be hidden from Commander-in-Chief Peng? On December 31, in order to break the conspiracy of the US military to "make a comeback", the volunteer army took the initiative to break through the "38th parallel" and launched a fierce attack on the "United Nations Army" led by the United States and the South Korean National Army that worked for it.
In this battle, the volunteer army sent six troops to attack from the "38th Parallel" to Seoul, annihilated more than 19,000 enemies, causing considerable losses to the US military.

On January 25, 1951, the "United Nations Army" took the initiative to attack the Volunteer Army that turned into defense and the Korean People's Army, but the Volunteer Army cleverly used space to exchange time and successfully completed the transfer under the eyes of the US military, turning danger into safety.
So far, China and the US military have fought in North Korea four times, each ending with China's victory, and the morale of the US soldiers has been greatly reduced.
chess matches the opponent
The situation on the Korean battlefield made the central government happy, but the US government on the other side was worried about it. Originally, participating in the Korean War was a big game set by the United States. They hoped that they could further leverage China through intervention in North Korea. To this end, they invested a lot of manpower and material resources in this war.

But what they didn't expect was that the victory that seemed to be natural is now out of reach, which also caused the top leaders of the US government to begin to doubt the commanders on the Korean battlefield.
Originally commanded the "United Nations Army" on the Korean battlefield, the MacArthur , who was awarded the US Army's five-star general. Before that, he had made great achievements in World War I and World War II , and was even known as the "youngest" war wizard.
KaOn the Korean battlefield, the answer he handed over made the US government very dissatisfied with him. On March 14, the then-US president, Truman , had serious differences with MacArthur on the North Korean issue. On April 11, Truman revoked the position of commander-in-chief of MacArthur and appointed the more cautious Li Qiwei as the commander-in-chief of the "United Nations Army".

Li Qiwei's war resume is far less "glorious" than MacArthur, but this US Army general has put the volunteers in the biggest crisis since entering North Korea.
After Li Qiwei arrived in North Korea, he tried to revitalize the fighting spirit of the "United Nations Army" while carefully studying the laws of the combat of the volunteer army.
Soon he discovered that although this team was brave and fierce in battle, the rhythm of the offensive often followed a cycle. Once this cycle exceeded, the volunteers would no longer carry out large-scale offensive operations, and the entire team would enter a defensive and rest state. Li Qiwei was very strange to this rule. After in-depth research, he found that the reason why the volunteer army followed such a strange rule was because the logistics support of this unit was very backward, and the materials it brought could only support the team for one cycle, but this cycle was not long, only about one week.
In fact, the problem of weak logistics of the Volunteer Army is not a secret. Before the Fourth Battle, the "United Nations Army" discovered this problem. They were going to rely on this weak click to defeat the Volunteer Army, but they never thought that they would have eaten up more than 70,000 troops.
However, Li Qiwei is different from the impulsive MacArthur. After discovering the problem, he formulated a clever plan that put the volunteers into a major crisis.

is better than the skills
The Volunteer Army has poor mobility and logistics support, but the US military not only has flexible armor, but also has relatively sufficient materials. Therefore, Li Qiwei decided to use the gap between the two to give the Volunteer Army a fatal blow.
If the plan formulated by Li Qiwei was shown to the volunteer army, the latter would probably feel extremely familiar. The tactics of luring the enemy into deep and flexibly strike were exactly what the volunteer army was good at, but this time, the original "hunter" of the Volunteer Army became the "prey" on the battlefield.
On April 22, 1951, the fifth battle broke out. Li Qiwei used such tactics to lure the volunteer army into the hinterland step by step, but such a "easy" battle situation quickly aroused Peng Dehuai's alertness.

Chairman Mao even saw through Li Qiwei's "scam" at a glance. Unfortunately, it was too late. The 100,000 troops pursuing the enemy had already entered the hinterland. At this time, the US military used the roundabout tactical intention to surround our army layer by layer. Commander Peng Dehuai was in a hurry to fight like this. He understood that the volunteer army was already scarce. If these 100,000 troops were eaten by the US military, it would be difficult to win the Korean battlefield.
However, facing such a situation, this veteran with rich experience on the battlefield really couldn't come up with any moves, so he had to ask the central government to ask Chairman Mao to give him advice.
After studying the battle situation, Chairman Mao found that Li Qiwei was indeed very capable in command. He learned to "learn from the barbarians' strengths to control the barbarians" and used our army's tactics to launch an attack on us. If this is the case, Li Qiwei would definitely have left a backup plan.

After careful study, the Chairman found that there are only two only nodes left in the eastern and western battlefields of our army: Tieyuan. Once this city is captured by the "United Nations Army", the supplies of the volunteer army will be completely cut off.
At the same time, Chairman Mao also noticed that although the 100,000 troops were in crisis, they still had considerable combat effectiveness. So he notified Peng Dehuai: gave up rescue and used attack instead of defending , so that the 100,000 troops would deal with the enemy. Since the enemy was interspersed, our army would do the opposite.
After receiving the telegram from the chairman, Peng Dehuai suddenly realized that he immediately ordered the 63rd Division to go to Tieyuan to defend, while other troops launched a series of anti-interruption operations. Facts have proved that Chairman Mao is more skilled than Li Qiwei. This 100,000 army gradually broke through the siege and escaped from the crisis through constant counter-interruption.

Summary:
The War to Resist U.S. Aggression and Aid Korea was a miracle in the war in Chinese history. When the United States first interfered in North Korea's internal affairs, many voices of the Party Central Committee disagreed with China's participation in the war, because in everyone's opinion, the United States at that time was an invincible world power, and China's new force was no match for it at all.
However, Chairman Mao opposed the opposition and believed that China should not only fight, but also win. The facts proved that Chairman Mao was correct.
He clearly recognized the passion and determination of the Chinese people, and correctly appointed Peng Dehuai, who had rich war experience as the commander-in-chief. Even if he encountered a crisis, Chairman Mao had enough military strategies to escape danger.
In this way, with the joint efforts of the Party and the people, China finally achieved the final victory on the Korean battlefield, proving to the world that China stood up.
