In the process of resisting US aggression and aiding Korea, due to the harsh meteorological conditions, the volunteer troops suffered serious losses in personnel and materials in the Battle of Changjin Lake. In the 89th Division, after receiving the order to prepare for battle, Division Commander Yu Guangmao quickly made a decision, that is, to let the 89th Division retain its own strength, so as to win the second phase of the battle. Despite the cold temperature on the battlefield and the unfamiliar terrain, the troops led by Yu Guangmao still fought bravely and fearlessly. How did the decisions he made lead the army to victory? 
When it comes to Yu Guangmao, many people may not know anything about his identity, but when it comes to the War to Resist US Aggression and Aid Korea, everyone knows about it. At that time, the battlefield environment was very difficult and the conditions were harsh. Yu Guangmao participated in the battle to resist US aggression and aid Korea, and took precautions before the battle, effectively avoiding the injuries suffered by the soldiers due to frostbite. "Changjin Lake", a movie released in 2021, presents the cruelty and hardships of the war at that time to the audience, and makes people deeply aware of the cruelty and hardships of this war. 
In October 1950, the Volunteers set foot on Korean soil and opened the curtain of the War to Resist US Aggression and Aid Korea. In the north of our country, winter in North Korea comes earlier and is colder than in the Northeast. The Volunteers suffered from extreme weather in the Battle of Changjin Lake, which was one of the main factors that led to their heavy losses. The temperature plummeted to minus forty degrees, and when the warriors of the South arrived on the battlefield, they were subjected to an unprecedented cold, which had a serious negative impact on their combat effectiveness. Of the 12 divisions of the Ninth Corps, there was one division with no more than 1000 frostbitten wounded, this unit was called the 20th Division of the 89th Army, and their number of frostbitten wounded reached 400 people. In the context of that era, this ** incident can be described as an incredible history. Yu Guangmao, who served in the 89th Division in mid-October 1950, was called up for training and would be ready by the end of October to meet the challenge of entering Korea. In early spring in November, the army began to move in the direction of the northeast. Due to the cold weather, everyone wore thick down jackets and coats. When the Tianjin station came to a standstill, they learned from the station's radio that the first battle on the Korean battlefield had officially begun. 
Before arriving in Tianjin, the train always maintains a cautious attitude to avoid any surprises when transporting goods. Once out of Tianjin, the military vehicles began to travel at high speed, and the freight trains along the way had to make them polite. When the military vehicles arrived in Shenyang, they received orders to go to Korea to fight. This is a very important task. When an order is received, the supreme commander of the train shall disembark and be led by a staff officer waiting at the station to the temporary command post. Yu Guangmao was ordered to lead the army to Changjin Lake to carry out combat operations. This is a cold and dangerous place, and you need to pay attention to a series of issues such as cold protection and food security. By mid-November, when the temperature in Shenyang had dropped to extremely low levels, Yu Guangmao felt the cold winter and began to worry about the warmth of the people around him. 
The army led by Yu Guangmao, many of the soldiers are from northern Jiangsu, and the climate in the south is relatively mild, even in the cold winter, the temperature will not drop to minus ten degrees. However, the temperature in Shenyang has dropped to a colder temperature than in northern Jiangsu, and North Korea is located further north, so it will be further reduced. Yu Guangmao immediately consulted with political commissar Wang Zhi, and the two went to visit the general staff together. They requested a one-day suspension of activities in Shenyang in order to provide the fighters with warm clothing and shoes during this time. After asking their superiors for instructions, the staff officers of the General Staff approved their request and assigned them to visit Deputy Commander He Jinnian of the Northeast Military Region. It was winter, and when the temperature dropped below zero degrees Celsius, freezing would occur, and the troops would need to wear thick quilts to survive the winter. With the assistance of He Jinnian, more than 10,000 teachers were provided with cotton clothes to protect their bodies from the cold. However, due to time constraints, the distribution of supplies was affected, resulting in a lack of cotton pants for half of the fighters, and the lack of necessities such as hats and gloves was even more acute! As time passed, they could no longer wait for supplies to be raised, so the military vehicles began to drive towards the border, and Yu Guangmao came up with a new plan. 
Yu Guangmao and the political commissar called on the soldiers to dismantle the quilts they had carried and process the cotton into small objects to protect their ears, hands and mouths, and these ear protections, gloves and masks became powerful tools for the soldiers to withstand the cold! When Yu Guangmao and his troops arrived in Korea, the temperature plummeted, but fortunately, his previous preparations were not in vain, because the cold clothing worn by the soldiers was basically effective in resisting the severe cold. Yu Guangmao immediately sent personnel to liaison, and participated in the second campaign, which began on November 27 and lasted until December 24. In the battle on November 30, the enemy carried out 7 fierce attacks on the 89th Division under the cover of powerful ** aircraft and tanks, but all of them were successfully repelled by our side! After defeating the enemy with inferior equipment, our army quickly launched a counterattack battle, annihilating two enemy brigades and one regiment, and achieving a major victory. With the arrival of December 2nd, the enemy began to flee the battlefield under our powerful attack. Yu Guangmao led the warriors, obeying the orders of their superiors, and pursued the fleeing enemy relentlessly, while actively preventing the reinforcement of enemy reinforcements. Under his command, the fighters surrounded the enemy with machine guns and grenades, and finally beat them to the ground and succeeded in relieving the wounded fighters. Based on the information transmitted by the previous troops, we are constantly making adjustments to keep up with the same pace. Under the leadership of Yu Guangmao, the army fought bravely and won successive victories, recapturing Wonsan and Heongnam Port one after another. Deputy Army Commander Liao Zhengguo highly praised the outstanding performance of the soldiers in the battle, believing that they showed extraordinary strength and courage in the battle. 
Yu Guangmao's foresight is not only reflected in the preparation of warm clothes for the soldiers, but also in his communication with the troops, showing his deep thinking and unique insights into the future. When Yu Guangmao received the training order, his mind was stimulated and he began to think about how to establish effective communication with the other party. He knows that communications equipment is an indispensable part of the troops' training, and at present the level of our army's equipment is still very low, and a batch of new equipment is urgently needed to enhance combat effectiveness. Therefore, he sent personnel to several large cities in Shandong, carrying the necessary funds and purchasing a large amount of communication equipment. When Yu Guangmao returned home, his eyes fell on the equipment, and after his careful calculations, he concluded that the equipment was not enough to meet his needs. Then, with his connections, he borrowed the necessary equipment from the army where he had been stationed. At that time, his tactics puzzled one of the staff officers of the communications service, who believed that in battle, communications equipment could be obtained through appropriations from superiors, so why should they buy it themselves? Yu Guangmao demonstrated his excellent preparation ability on the Korean battlefield and contributed greatly to the victory on the battlefield. He loaded all the vehicles into it. When entering the territory of Korea, the warriors of a division were assigned to more than twenty vehicles and finally arrived at Ji'an on the Yalu River, where many armies gathered and were numerous. 
We are unfamiliar with the terrain of North Korea and do not speak their language, so we are faced with the thorny problem of how to establish effective connections. Yu Guangmao's army was well prepared, they were able to maintain close contact between the regiments, and they were able to command the battle in the camp. As a result, after the start of the battle, almost none of their troops lagged behind the ranks. 
Yu Guangmao has always maintained a high level of attention to logistics on the battlefield, and once he has captured clothes and quilts that can effectively keep warm, he will quickly organize personnel to send them to the soldiers on the front line to ensure that they have enough energy to fight. War is a brutal war, and it is full of many unknown variables. With his many years of actual combat experience and keen prediction ability, Yu Guangmao laid the most solid foundation for the victory of the soldiers of the army and made full preparations. It also reminds us to think carefully and prepare well before we act, so as not to fall into unprepared situations!
