The number of casualties in the volunteer army was increasing day by day. Chairman Mao sent someone to the Korean battlefield to reverse the situation.

After the formal division of North and South Korea, neither side gave up the goal of reunification. Taking the 38th parallel as the boundary (hereinafter referred to as the 38th parallel), armed conflicts continued nearby, which eventually led to the North Korean war on June 25, 1950. day outbreak.

The movement to resist U.S. aggression and aid Korea is part of the Korean war. It only refers to the part of our volunteer army that participated in the war. It also includes the mass movement of our people. It only refers to the movement to support the Korean people in resisting the aggression of U.S. imperialism. At this stage, there are many battles that reflect the fighting spirit of our volunteers. One of them is a story about one person turning the tide of the war. How did it happen?

On September 15, 1950, the U.S. Front Army landed at Inchon, which is the western coastline of the Korean Peninsula. The Korean People's Army was attacked from both front and back, causing huge losses, and then entered a stage of strategic retreat. Subsequently, Premier Zhou delivered a speech: The Chinese people will never tolerate foreign aggression, and will not turn a blind eye to the aggression against their neighbors.

MacArthur concluded that we did not dare to send troops to compete with them, so he ignored our many warnings. On October 1, he crossed the 38th Parallel and captured Pyongyang. He also intended to quickly occupy the entire North Korea. At the same time, American planes repeatedly invaded our airspace and even bombed the Dandong area. The flames of war were about to reach the banks of the Yalu River.

On October 8, 1950, in order to request us to send troops for assistance, the North Korean government issued an official request. We responded to the request of the North Korean government and sent troops to assist North Korea in order to defend our homeland. On October 25, our People's Volunteer Army fired the first shot to aid Korea, and the movement to resist U.S. aggression and aid Korea officially began.

In the first stage of the War to Resist US Aggression and Aid Korea, that is, from October 25, 1950 to June 10, 1951, our Volunteer Army joined forces with the North Korean People’s Army to use mobile warfare as the main combat method, supplemented by positional warfare and guerrilla warfare. In this way, five strategic battles were carried out.

In the second stage of the War to Resist U.S. Aggression and Aid Korea, that is, from June 11, 1951 to July 27, 1953, during this stage, the Chinese and North Korean people adopted the policy of protracted warfare, focusing on positional warfare, and actively defense. Military operations and armistice negotiations are closely integrated, and negotiations are carried out while fighting to promote mutual coordination.

At this stage, a character emerged. He was a character that the commanders rushed to recruit, and he repeatedly performed extraordinary feats. Who is this character? He is Wang Yaonan, the founding major general and one of the founders of the engineering corps.

Wang Yaonan, Major General of the People's Republic of China and the founding of the People's Republic of China, is one of the founders of the engineering corps. He is known as the "King of Mine Warfare" and "King of Engineers". His life is a history of China's engineers and soldiers.

In order, he experienced the general strike in Anyuan, the reorganization of Sanwan, the struggle in Jinggangshan, five anti-encirclement and suppression campaigns, the 25,000-mile Long March of the Red Army, the War of Resistance Against Japan, the War of Liberation, Resist US aggression and aid Korea.

He also organized and commanded tunnel warfare and mine warfare, with outstanding achievements. He made great contributions in the War of Resistance Against Japan, the War of Liberation, and the War to Resist U.S. Aggression and Aid Korea. He experienced more than 300 battles and was seriously injured five times, but he never retreated.

Wang Yaonan was born in Shangli Village, Pingxiang, Jiangxi. Although there are less than 100 households here, the village is famous for making firecrackers. Wang Yaonan began to learn the craft of making firecrackers from his uncles when he was 5 years old. He is smart and willing to study hard. Over the past few years, he has not only become technically proficient, but has also mastered the recipes for making dozens of firecrackers. He is among the best among people of his age.

In 1919, half of Shangli Village disappeared due to an accidental explosion of a medicine pack. Reluctantly, her mother took the young Wang Yaonan and her younger sister to beg and seek refuge with their father. At that time, my father worked as a blaster in the Pingxiang Coal Mine in Anyuan. He earned a meager income and worked hard to support his family.

In Anyuan, local bureaucracy and imperialism colluded with each other to turn Anyuan into a hell on earth. Anyuan became the birthplace of our party's leadership of the workers' movement, one of the main outbreak sites of the Autumn Harvest Uprising on the border between Hunan and Jiangxi, and the military center where our party's Hunan Provincial Committee directed the uprising.

After Wang Yaonan arrived in Anyuan, he followed his father to learn to be a blaster. He shouldered an extraordinary burden at a young age. When the great man who served as Party Secretary of Hunan regarded the development of the labor movement as the focus of his work, he came to the Pingxiang Coal Mine to spread the fire of revolution. The easy-to-understand and profound revolutionary principles took root in the heart of young Wang Yaonan and slowly grew up.

In 1922, Li Lisan founded the first tutorial school for road miners to secretly spread our party's ideas. Such thoughts caused great shock to Wang Yaonan. Later, he joined the Anyuan Children's League organized by our party and began to perform revolutionary tasks.

Once, workers were holding a secret meeting underground in the mine. The foreman suddenly came to check on the job. Wang Yaonan, who was on guard duty, saw this and had an idea. He shouted loudly and rushed forward: "Uncle, you are here." The foreman immediately scolded: "What are you shouting for!"

Then he used his whip. Go and beat Wang Yaonan. Wang Yaonan took advantage of the situation and shouted louder: "Oh, why are you hitting people?" Upon hearing the "signal" sent by Wang Yaonan, the workers understood and quickly dispersed.

The Anyuan strike began in 1922. 11-year-old Wang Yaonan rushed to the front of the team, shouting revolutionary slogans: I used to be a cow and a horse, but now I want to be a man. He also led his friends from the children's league to paste flags, put up slogans, distribute leaflets, and sing "Labor Song." The powerful singing voice sounded loud and clear, shaking the crumbling old society.

Under the leadership of the party and with the support of the whole country, the general strike finally won. Comrade Liu Shaoqi has said many times that without workers like Wang Yaonan, it would be difficult to win a general strike. Young Wang Yaonan experienced the baptism of revolution.

In the spring of 1952, on the battlefield of North Korea. The "United Nations Forces" led by the United States accepted the lessons of the summer and autumn offensives and used small-scale offensive operations and air force sabotage activities to maintain their defense lines and cooperate with their negotiations.

In order to consolidate the existing positions and persist in protracted operations, our side creatively established a very solid defense system with tunnel fortifications as the main aspect and combined with field fortifications. Among them, the tunnel fortifications are the mountain tunnel warfare tactics created by Wang Yaonan based on the idea of ??plain tunnel warfare and the actual local conditions.

The mountain tunnels could withstand even enemy heavy bomb attacks and heavy eight-inch (200 mm) artillery bombardments. The number of our casualties in each army dropped from the previous 80 per day to 2-3. The mountain tunnels are praised by the troops as an underground steel Great Wall that cannot be destroyed by bombing or defeating. By the end of the Korean War in July 1953, the entire 38th Parallel Mountain was almost hollowed out.

Summary:

Mountain tunnels are crisscrossed in the mountains along the 38th Parallel. It played a vital role in preserving the strength of our army. It completely solves the problems of stationing and raising troops for front-line mountain troops, and perfectly combines offense and defense.

Wang Yaonan creatively developed mountain tunnel warfare based on plain tunnel warfare, which effectively resisted the enemy's heavy artillery and aerial bombing attacks, greatly reduced casualties, preserved the strength of our army, and consolidated the March 8th victory. It played an extremely important role in the mountain defense of the line and successfully turned the tide of the war, which shocked the world.
