In April 1951, our army officially launched the fifth campaign of the War to Resist US Aggression and Aid Korea. In this battle, our army invested an unprecedentedly large number of troops, intending to annihilate 3 to 4 entire divisions of the American army. However, it is a pity that our army did not realize that this move greatly underestimated the strength of the US military, and at the same time greatly overestimated the capabilities of our army. 
In the first three battles, our army went smoothly and hit the 37th parallel from the Yalu River, beating the "United **" and crushing the army. However, in the fourth battle, after Lieutenant General Ridgway officially took over the baton, the offensive and defensive momentum was reversed. Unlike MacArthur, who was arrogant and eloquent, Ridgway was cautious and good at research. In the fourth campaign, Ridgway had generally figured out the lifeblood of our army, that is, logistics. Since our army has no air supremacy, and the supply lines are not guaranteed, the first situation can only last for a week. After a week, all the ammunition and food will be gone. Therefore, Ridgway called the offensive of our army a "worship offensive". Therefore, in the actual battle, Li Qiwei adopted the tactic of luring the enemy. He ordered Van Vleet to retreat only 32 kilometers a day, to avoid night battles and close combat with the volunteers as much as possible, and to rely on long-range artillery in depth to consume the strength of our army. At the same time, the U.S. military also sent air power to endlessly bomb the supply lines of our army. In this way, the "United **" fought and retreated, and after four weeks, our army again approached the vicinity of Seoul. However, our army has run out of food and ammunition, and the soldiers are exhausted. However, the US military, relying on its mechanized superiority, was calm and relaxed, and did not suffer serious losses. Only then did I realize that annihilating several enemy divisions while the enemy was on guard was a task that could not be completed at all. 
The situation is already quite critical, but the vast number of soldiers of our army think that the US troops are only timid in fighting, so they often say in a contemptuous tone: "The American soldiers are not good, and they dare not fight with us with bayonets." "But on May 22, the situation of the war suddenly changed, and the US army, which had been recuperating for a long time, suddenly launched a rapid **, and its tactics were exactly the detours and intersperses that our army is good at. However, compared with the trekking interspersed by our army, the penetration of the American army is rapid and ferocious. The US army concentrated its armored forces and formed elite assault forces such as the Commando Team of the 7th Regiment of the 1st Cavalry Division, the "Derwin Armored Detachment" and the "Niu Man Elite Soldiers" to move quickly to the rear of our army, while the 13 divisions composed of 10 countries followed. Within 3 hours, the "Niu Man Pioneers" interspersed 20 kilometers and cut off the Song Shilun Corps, and hundreds of thousands of troops were in danger of being completely annihilated by the US army. However, after all, our army is a division of a hundred battles, and the generals are all generals of a hundred battles. Our troops covered each other, retreated step by step, and finally broke through the enemy's encirclement. However, it is a pity that the 60th Division of the 180th Army was delayed in retreating due to the erroneous understanding of the command of the superiors, and was finally almost annihilated by the enemy as a formation. Although the main force of the volunteer army has temporarily escaped from difficulties, it does not mean that our army has been out of danger. This is due to the fact that the superiority of the equipment of the "United **" is too great, and if our army does not block it, the enemy's mechanized troops will again penetrate behind our army. At that time, hundreds of thousands of volunteers will face the end of being surrounded and annihilated. 
Therefore, *** has drawn a line in the Cheorwon area, and there must be a force behind the palace here. This is because Tieyuan is our army's logistics supply base, and at the same time, it is also a transportation hub, with dense roads and railways, which can be attacked and retreated. As long as we control here, we can quickly move our army north. Once this place is occupied, the situation will be dire. The 19th Army Corps of the Chinese People's Volunteers and the 1st Army Corps of the Korean People's Army were in danger of being completely annihilated. However, the transportation hub is inevitably flat and flat, which is where the US mechanized troops come in. And it is too late to build fortifications on the spot. At this time, the elite of the "United **" came out, and the troops of ten countries including the United States, Britain, South Korea, Canada, Turkey, and the Philippines surged towards Tieyuan, and a decisive battle that decided the lives of hundreds of thousands of volunteers began. In order to stop the enemy, ** gave a rare and difficult order to defend Cheorwon with the 63rd Army. The 63rd Army was subordinate to the 19th Corps and numbered about 24,000 people. They had to defend a position with a frontage of more than 25 kilometers, and they were faced with four entire divisions and 50,000 troops of the US army. In terms of equipment, it is even more incomparable. The US military has more than 1,600 artillery pieces of various types, more than 300 tanks, and hundreds of planes floating in the air. ** ordered that the 63 Army must block the joint ** for 15 to 20 days. Yang Dezhi, commander of the 19th Corps, believed that there was no certainty of victory in blocking the enemy army in Tieyuan. In terms of numbers and equipment, our army is at an absolute disadvantage. The 63rd Army simply did not have time to prepare, and it was difficult to complete the task of the Zhiji. 
**I have always loved soldiers like children, but there is no room for tears on the battlefield. If the 63rd Army is not sacrificed, hundreds of thousands of volunteer soldiers will face extreme danger. Therefore, *** had to issue this impersonal order, and did not give Yang Dezhi any room to speak of difficulties at all, he said in a hoarse voice: "Even if the 63rd Army is wiped out, you must hold on to Tieyuan for 15 to 20 days." After the 35-year-old young army commander Fu Chongbi received the order, he said tragically: "Even if the 63rd Army fights to the last man, it will not let Van Vleet advance another half a step." In this way, the bloody and tragic Battle of Cheorwon began. 
On June 1, 50,000 "United**" troops from 10 countries, supported by tanks, artillery and aircraft, launched a tsunami-like attack. Fighting the plains with such an enemy, even if 100,000 more people come, it will not be enough. Although it is true that our army wins by numbers, it will never use the "crowd tactic" of "piling up lives". According to the characteristics of the enemy's army, Fu Chongbi adopted a new tactic, that is, to deploy troops in depth and echelons, with fewer troops in the front and more troops in the rear. After the soldiers in the front were killed, the rear went up again. At the same time, the 63rd Army also arranged a number of tactical groups to constantly entangle the enemy's march and prevent the enemy from proceeding smoothly. At the same time, the 63rd Army will never be passive and stubborn. At night, our army will also organize night detachments to raid the opponent. Although the tactics were very clever, the enemy's artillery fire was not vegetarian. Van Vleet once again showed his "ammunition volume", and in just one hour the enemy poured 4500 tons of artillery fire on the positions of our 189th Division. ** The smoke obscured the sky and the sun, and Cai Changyuan, the 189th Division, immediately dispersed the whole division into more than 200 units to form more than 200 "nails". Swinging a "gossip array" on the position, so that the enemy army will not be able to use artillery fire to gather and annihilate the main force of our army. At the same time, our army uses these "nails" to cross cover and block the enemy at every level. Although the U.S. military was indeed able to capture some positions, it would take a lot of time. After the success of the tactics of the 189th Division, the 187th and 188th Divisions began to follow suit, giving the enemy an advantage in equipment, but never being able to move forward. In addition, Cai Changyuan also found that although the US military is strong, its operations are relatively rigid, and it hopes to advance step by step and layer by layer, so it is not good at dealing with opponents in sports. Therefore, the defense of our army is no longer confined to positions, but is constantly adjusted. If the ** is too large, the regiment will be reduced to a battalion, the battalion to a company, and the company to a platoon. When the establishment is dispersed, combat groups are temporarily organized. Therefore, although our army is very large, it can still ensure strong combat effectiveness. 
At the same time, the grassroots officers of our army also displayed their ingenuity and invented various tactics. For example, Guo Enzhi, the squad leader of the 188th Company of the 563rd Regiment of the 8th Division, invented the "three flowers" tactic. In defense 2551. On the high ground, Guo Enzhi flexibly used mortars. First, one shell is fired at the front and rear of the enemy's formation, one shell on the left and right, in the shape of a plum. Drive the spreading enemy into the middle, then fire a third shell to inflict a large number of wounds on the gathered enemy. Subsequently, our troops quickly attacked from both sides of the position, encircling and annihilating the enemy. It was with this clever infantry tactic that the 8th Company blocked the attack of a reinforced regiment of the 1st Ace Cavalry Division of the US Army with only 16 people. By the end of the Battle of Cheorwon, there were only more than 20 people left in the whole company, and when they broke through, there were too many enemy corpses in front of the 8th Company's position to put their feet down. At this time, the bloody battle of Tieyuan also affected the heart of ***. The headquarters of ** is only more than 100 kilometers from the front line, and it takes only 2 days for enemy tanks to storm here. However, *** did not listen to the persuasion of his subordinates, and refused to evacuate. The 63rd Army has not withdrawn, how can it be withdrawn?
In 14 days, the 63rd Army fought bloodily with the "United **", **up to 220,000, and even the army commander Fu Chongbi was seriously injured. However, the 63rd Army has completed its mission behind the palace, and the main forces of our army have withdrawn to the 38th parallel and established a strong defensive line. The 63rd Army is huge, but it also makes the "United Army" kick to the iron plate. The enemy's losses, there are also 150,000 as much. With the support of friendly forces, the rest of the 63rd Army withdrew to the rear and personally visited the officers and soldiers of the 63rd Army, who were ragged and covered in blood. ***, who never shed tears, just said "The motherland thanks you", and he was choked up and speechless. Four days later, Fu Chongbi, the commander of the 63rd Army, woke up on the operating table, and faced Mr. Peng, his words were "I want soldiers". Just a week later, 20,000 recruits were added to the 63rd Army. The Cheorwon Resistance War represented the end of the large-scale movement war of the War to Resist US Aggression and Aid Korea. The United States and its client states also retreated because of the huge **, and finally stopped at the 38th parallel, and the two-year-long confrontation began. With its wisdom and courage, the 63rd Army finally blocked the strong opponent, he defended his honor with his blood, and also protected hundreds of thousands of comrades-in-arms, who were immortal.
