Total: The Ninth Corps of the Volunteer Army entered Korea on November 7, 1950, and the 27th Army lost 700 people on the first night after crossing the Yalu River. On November 13, in Zhongjiang Town, the third battalion of the 237th Regiment of the 79th Division of the 27th Army held a meeting of cadres above the company level, and was bombed by US planes, more than 20 people were burned to death by incendiary bombs, and all 14 battalion and company cadres attending the meeting were killed. This was also the first batch of casualties of the Ninth Corps into Korea.

At that time, the intelligence of the Volunteer Army showed that in the Changjin Lake area, the US army only had two regiments and one forward command post. As a result, the 9th Corps was deployed, with the 27th Army attacking the 2nd US regiment, and the 20th Army being responsible for cutting off the communication between the US military units and attacking the US forward command post. And the 26th Army served as the general reserve of the Corps on the border between China and North Korea. The original plan was to launch a simultaneous offensive with the Western Front on the night of 25 November, but due to heavy snowfall, the difficulty of the troops' march, and the bombing of US planes, almost all the cars were blown up, and the logistics could not keep up. (Among them, the artillery of the 26th Army was also blown up during the later march.) This is also an important reason for the tragic results of the 26th Army in the subsequent battles. In the end, the campaign was postponed to the evening of the 27th.

By 26 November, the actual strength of the US troops was as follows: The forward command post of the 31st Regiment of the 7th US Division, the third battalion of the 31st Regiment, an artillery battalion, and a self-propelled antiaircraft artillery company were in Sinsing-ri, the second battalion of the 32nd Regiment and the heavy mortar company of the 31st Regiment were in Naedongzhi northwest of Sinsing-ri, and the headquarters of the 31st Regiment, a tank detachment, and an engineer company were in Houpu, south of Sinung-ri, plus a part of the ROK army. There are more than 4,000 people in total.

Xiajiayuli is the forward command post of the 1st Marine Division, the 3rd Battalion of the 1st Marine Regiment, the 1st Battalion of the 7th Marine Regiment, the 2nd Battalion of the 11th Artillery Regiment, two engineer battalions, and a tank detachment, as well as logistics units, the Navy, Air Force, Army Joint Logistics Communications Unit, and part of the ROK Army, totaling more than 3,900 people.

In Liutan-ri are the 7th Marine Regiment, the 1st and 2nd Battalions of the 5th Marine Regiment, the 11th Artillery Regiment and part of the ROK Army. More than 8,600 people in total.

The other units of the 1st Marine Division were on the line south of Changjin Lake from Fushengli, Gutuli to Zhenxingli. So far, the U.S. troops in the Changjin Lake area have doubled the estimate of the Ninth Corps. In addition, there are the 7th Regiment of the US 3rd Division in Shecang, southwest of Changjin Lake, and the US 7th Division and the 3rd Korean Division to the east of Changjin Lake. There are also seven aircraft carriers of the US Navy and the US Far East Air Force providing air support on the sea.

The battlefield intelligence was inaccurate, the US military's firepower superiority and mobility capabilities were not clearly understood, and the US military was not well prepared for extremely cold weather, and the Ninth Corps was doomed to indelible wounds before the battle began.

27 November:

During the day, the U.S. troops in Liutanli launched an attack, but were strongly blocked by the volunteers, and the U.S. troops advanced less than 1.3 kilometers, but this also aroused the vigilance of the 1st U.S. Army Division, and immediately arranged a circular defense ring in Liutan.

In the evening, the 9th Corps launched an offensive on all fronts.

The 79th Division of the 27th Army and the 267th Regiment of the 89th Division of the 20th Army stormed Liutanli and occupied part of the highlands in Liutanli overnight. However, the U.S. forces here were the main force of the U.S. 1st Army Division, and the U.S. troops launched a counteroffensive during the day with the cooperation of aircraft, tanks, and artillery, and many positions were lost. In the days that followed, the two armies fought back and forth.

The 80th Division occupied the high ground separating Sing-ri from Naedong-ri and the high ground around Sing-ri. The 242nd Regiment of the 81st Division occupied the 1221st Heights between Sinse-ri and Houpu.

The 281st Regiment of the 94th Division of the 27th Army confronted the 1st Division of the US 7th Division in the direction of Huishan on the Yalu River, and the other 2 regiments served as reserves in Liutanli. The 241st Regiment and the 243rd Regiment of the 81st Division monitored the troops of the US 7th Division and the ROK 3rd Division in the direction of Zhanzhan Lake east of Sinsing-ri.

The 20th Regiment of the 59th Division of the 175th Army attacked the 1419 Heights between Liutanli and Xiajieyuli, but failed. At dawn the next day, when the attack was organized again, it was thrown napalm by the US Air Force, and suffered heavy casualties.

The 177th Regiment occupied Dead Eagle Ridge and Xixingli between Liutanli and Xiajieyuli, but the attack on Dedong Pass was unsuccessful. Dedong Mountain is located next to the Dead Eagle Ridge, which is the main peak here, the mountain is high and the road is dangerous, and it can be continuously supported by the 105 howitzer group in Xiajieyuli, but it has never been overcome. Later, it became a strong support point for the retreat of American troops in Liutanli.

The 178th and 179th regiments of the 60th Division occupied the high ground on both sides of the road from Gutuli to Xiajieyuli, while the 180th Regiment advanced to Huangcaoling, south of Gutuli.

The 265th and 266th regiments of the 89th Division entered Shecangli.

The 58th Division originally planned to attack Xiajieyuli, but due to a map error, it was unable to cross the mountains and mountains, resulting in an additional 70 kilometers of detour, and it was unable to launch an attack on time. This mistake caused the US troops in Xiajieyu to construct a 6-kilometer-long defensive ring for a whole day on the 28th, causing irreparable consequences to the Ninth Corps.

November 28:

At dawn, the U.S. troops in Liutanli began to attack the Dead Eagle Ridge, and the 2nd Battalion of the 7th Marine Regiment in Xiajieyuli attacked Xixingli, and the 59th Division was attacked on both sides.

During the day on the same day, the U.S. Army in Houpu attacked the 1221 Heights, but was blocked by the 242nd Regiment of the 81st Division, and the U.S. Army failed to break through and was forced to retreat.

In the evening, the 80th Division stormed Neidongzhi and Xinxingli, and at dawn the next day, the U.S. troops withdrew to Xinxingli. During the retreat, Colonel McLean, commander of the 31st Regiment of the 7th US Division, was wounded and captured, and died of his wounds four days later. The 31st regimental combat team was succeeded by the commander of the first battalion of the 32nd regiment, Feith.

In the direction of Xiajieyuli, the 58th Division launched an attack, concentrating the artillery of the whole division, 18 guns of 82 and 54 guns of 60, with 90 rounds of ammunition and 120 rounds of ammunition to fire. A US regiment is equipped with five tanks, 12 107 guns, 24 75 recoilless guns, 30 81 guns and a number of 89-mm rocket launchers, and has countless ammunition in reserve, and it is also equipped with 18 105 howitzers of an artillery battalion during combat. That night, the US military fired more than 8,000 shells.

That night, the 172nd Regiment occupied Dongshan and the nearby heights. The 173rd Regiment once broke through the airfield defense line, but after all, the firepower was too weak to widen the gap, and the troops suffered too many casualties in the continuous attack, and withdrew from the battle at dawn on the second day.

That night, the main force of the 89th Division of the 20th Army exchanged fire with the 7th Regiment of the 3rd Division of the United States in Shecang.

November 29:

During the day, the U.S. troops in Xiajieyu attacked the Dongshan 1701 Heights, and they died on the small Gaoling Heights next to them.

In the evening, the US army covered and bombed the Dongshan position with artillery and night fighters, and the 58th Division was unable to assemble for an attack.

In the direction of Gutuli, a task force composed of the 41st Commando Group of the British Royal Marine Corps, two infantry companies of the 1st Marine Division, two tank platoons and other fire units went north to support Xiajieyuli. Surrounded and intercepted by the 178th Regiment and the 179th Regiment of the 60th Division, more than 300 people and 17 tanks finally broke into Xiajieyuli, more than 300 casualties, and the remaining 237 surrendered to the 179th Regiment at 8 am on the 30th.

30 November:

During the day, the U.S. forces in Xiajieyuli continued to storm the Dongshan 1701 Heights.

In the evening, the 58th Division organized the remaining forces to attack Xiajieyuli from the Dongshan position, but finally failed to break through due to the lack of attack points and the lack of follow-up forces. After that, the 58th Division of Dongshan Heights fought repeatedly with the enemy until the evening of December 5, and the blood of the 58th Division was dried here.

On the evening of the same day, the 27th Army concentrated the 238th, 239th, and 240th regiments of the 80th Division, the 4 regiments of the 241st Regiment of the 81st Division, and all the artillery of the whole army to besiege Xinxingli.

December 1:

The U.S. troops in Liutanli broke through the encirclement in an all-round way and attacked Death Eagle Ridge. The 79th Division of the 27th Army occupied the high ground on the west side of the northern section of the road, and the 94th Division occupied the high ground on the east side of the northern section of the road, but the 79th Division was already exhausted, and the 94th Division had lost thousands of troops after freezing in the ice and snow for a few days.

In the afternoon, the 27th Army entered Xinxingli and captured the regimental flag of the "Polar Bear Regiment". The U.S. 7th Division decided to break through but its command was confused, and after 4 p.m., Pu's U.S. troops withdrew to Xiajieyuli, resulting in no one answering the U.S. troops who broke through. Lieutenant Colonel Faith was killed while directing the breakout, and the Americans broke up and fled over the ice. By the end of the battle at 4 a.m. on December 2, more than 2,000 enemies had been killed in this battle, and 1,050 had fled back to Xiajieyuli, of which only 385 were all bearded and tailed. The 5th Company of the 242nd Regiment of the 81st Division all froze to death on the blocking position, which was the first "Ice Sculpture Company".

The 31st regiment-level combat team of the 7th US Division was annihilated, and the 1st was exaggerated in strength, although it had the title of "Polar Bear Regiment", its actual combat strength was the level of the ordinary US Army, and it could not be compared with the 1st Marine Division of the US Army. This is also the reason why the Ninth Corps decided to attack him first after adjusting the operation. 2 is that the defense is loose, and the troops are stationed in three places, and they are divided as soon as the war begins. Later, although there were two combined forces, they did not form a ring defensive circle, and the defense line was distributed in a belt, and then it was broken through by the 27th Army. 3. The command was disordered, and after the breakthrough was determined, the Houpu troops received orders to retreat ahead of schedule, resulting in the failure of the troops to break through to this point. 4. The will to fight was weak, the supreme commander fled far away from the battlefield, and after the death of the two battlefield commanders, the third commander gave up command, more than 1,000 people fled, and the remaining troops fought separately.

On the side of the Ninth Corps, the battlefield reconnaissance was ineffective and the intelligence was inaccurate, resulting in the fact that the principle of concentrating forces to annihilate the enemy could not be reached at the very beginning of the campaign. A division of the 79th Division attacked the main force of the 1st Division of the US Army, and it could not be beaten down, encircled, and failed to encircle. A division of the 58th Division besieged the command and logistics base of the 1st US Army Division after a one-day delay, but it could not be defeated or encircled.

At that time, under the influence of hunger and cold, the Ninth Corps was the strongest in the first night, followed by the second night, and then the combat strength fell to a new level, whether it was the receiving troops, the latent troops, or the reserve troops, the actual combat strength had been greatly reduced.

The US military has no understanding of the ability of the US military to fight in an integrated air-ground operation, and the offensive combat casualties are huge, and the strategy of occupying the high ground on both sides of the highway to block the enemy has actually failed to achieve the expected results.

At this point, the combat attrition of all units of the Ninth Corps, freezing to death and frostbite was extremely serious, and the food and ammunition were almost exhausted, and in fact they were no longer able to carry out offensive combat missions.

December 2:

The 79th Division of the 27th Army fought bloodily with the breaking US troops in the northern section of the Liutan-Xiajieyuli Highway and the 59th Division of the 20th Army in the eastern section of the Liutan-Xiajieyuli Highway.

December 3:

The 241st and 242nd regiments of the 81st Division of the 27th Army, which ended the battle in Xinxingli, crossed Changjin Lake and occupied the high ground on the north side of the eastern section of the road. However, the Dead Eagle Ridge position was broken through by the US army, and the US army at Dedong Pass lost more than half of its company, but it still held the position for 6 nights and 6 days, and captured nearly 100 volunteers. The 20th Division of the 59th Army withdrew from the battle, and there were only more than 60 people left in the first battalion of the 177th Regiment, but they did not withdraw after receiving the order to retreat, because their hands and feet were frozen, and they couldn't climb until they couldn't climb, and they were not carried back until night. The second battalion of the 177th regiment insisted on retreating until dusk, and all 6 companies of them froze to death on the blocking position.

At 7 p.m., the vanguard of the US army had arrived at Xiajieyuli. At 22 o'clock in the evening, the 81st Regiment of the 243rd Division rushed to the vicinity of Xixin.

I don't know if it was a problem of communication delay or a problem with the reporting of the battle situation, but late at night on the 3rd, *** was still calling the Ninth Corps, asking it to speed up the mobilization of the 26th Army, besiege the US troops in Liutanli, and implement the operational plan of encircling the point and sending reinforcements.

December 4:

The 243rd Regiment of the 81st Division and the U.S. Army repeatedly fought for the high ground near the West Heart. After all, it belonged to the U.S. military during the day, and it was all withdrawn to Xiajieyuli by the U.S. military. More than 1,500 U.S. troops were killed or wounded in Liutanli.

December 5:

The U.S. troops in Xiajieyu prepared to retreat and began to evacuate the wounded by air. By the second day, thousands of wounded were transferred.

On the same day, the 89th Division of the 20th Army fought with the 7th Regiment of the 3rd US Division from Shecang-ri until Xiatongli and then withdrew from the battle.

At 8:10 p.m., two U.S. B-26 bombers dropped six 500-pound bombs to bomb Xiajieyuli. The oil was hit, and the flames soared into the sky, reflecting the entire sky, and the American army and the volunteers were stunned.

Late at night, the 76th and 77th Divisions of the 26th Army rushed to Xiajieyuli and handed over positions with the 58th Division. Its 88th Division was still grinding on the road, and the 78th Division was covering the entire corps flank on the Eastern Front. The 26th Army originally planned to launch an attack on the night of the 6th, but the US troops began to attack and retreat at dawn, and the 26th Army was forced to respond in a hurry.

6 December:

At 4:30 a.m., the U.S. forward began a retreat operation, engaged in a fierce battle with the 76th Division, and broke through the blockade in the afternoon and left Xiajieyuli.

At 7:30 a.m., the U.S. rearguard began to attack the Dongshan position, which was occupied at 14:30 p.m. The Volunteer Army organized a counterattack but was incompetent in command, and even organized troops to prepare for the attack in broad daylight on the ridge between the first two hills of the 1701 Heights. It was immediately bombed indiscriminately by US planes, causing heavy casualties. The US ground forces seized the opportunity to occupy the hills on both sides and blocked the retreat route of the unit with heavy firepower. Unable to defend or retreat, the unit was unilaterally slaughtered by the U.S. military, forced to surrender, and eventually captured 220 people.

In the evening, the 26th Army again organized a counterattack on the Dongshan position, but it was unsuccessful.

December 7:

At 2 o'clock in the morning, the 26th Army once again organized a full-scale onslaught on the Dongshan position and the retreating US troops overnight, but it was still unsuccessful. The Battle of Dongshan, which began on the night of November 28, is also known as the Battle of Dongqiu, which is widely known in the history of the U.S. military.

At 6 o'clock in the morning, the US rearguard began to retreat, and the 76th and 77th divisions were still fighting stubbornly. At the same time, the US forward arrived at Gutuli, and at 10 o'clock in the morning, all the forward troops entered Gutuli.

At 8 o'clock in the morning, the US rearguard exchanged fierce fire with the 88th Division of the 26th Army, which had just arrived, and broke through the blockade at 15 o'clock in the afternoon.

In these two days and one night, the 26th Army was stunned, and its main force, the 76th Division, lost more than 6,000 people, and it can be said that the combat troops were completely lost.

At midnight that day, the 1st U.S. Army Division withdrew to Gutuli, and more than 600 people were killed or wounded in the entire retreat process. Lieutenant Colonel Harris, the son of General Harris, commander of the U.S. Naval Air Force, was killed while leading a team to cover the retreat of the 1st Army Division's baggage transport team. When this person was fighting in Liutanli in front, he ordered a company to withdraw from its position to protect the safety of his battalion headquarters.

December 8:

At 2 o'clock in the morning, as soon as the American troops arrived at Gutuli, they began to retreat and march towards Huangcaoling. The famous three bombings of the Watergate Bridge took place here (on December 1, the 60th Division bombed the first time, on December 4, the 60th Division bombed the second time, and on December 6, the 58th Division 172nd Regiment bombed the third time). Blocking the north of the Watergate Bridge was the remnants of the 58th Division of the 20th Army, about 6~7 companies, each company was less than 100 people, led by Hu Qianxiu, chief of staff of the division, and Hao Liang, political commissar of the 174th Regiment. Unfortunately, the command post was discovered by US planes, and the rockets went directly into the cave where the command post was hiding, and all the members died.

The U.S. troops who went north from Zhenxingli to meet attacked Huangcaoling, south of the Watergate Bridge, where the 60th Division was defended, but the 178th and 179th regiments were disabled, and although the 180th Regiment did not have many combat missions in the early stage, it was very difficult to lose its personnel while lying on the ice and drinking snow.

December 9:

The Watergate Bridge was repaired for the third time, and all 50 soldiers of the 172nd Regiment of the 58th Division on the hill next to it froze to death on the position.

On the 1081 heights of Huangcaoling, the 2nd Company of the 180th Regiment of the 60th Division of the 20th Army all froze to death on the position, which was the third "Ice Sculpture Company". Because it was first discovered by the U.S. military, the deeds of the "Ice Sculpture Company" were the most widely spread. The company's battalion consisted of 666 men, and by the time they were withdrawn from the battle, only 16 were able to move on their own.

On the same day, the 26th Army rushed to Gutuli, but could not prevent the retreat of the American troops.

December 10:

The 1st U.S. Army Division all passed the Watergate Bridge and retreated across Huangcaoling to Zhenxingli. There were only more than 100 fighters left in the 58th and 60th divisions of the 20th Army, and they were still stubbornly pursuing.

December 11:

At 1 o'clock in the morning, dozens of people from the 20th Army caught up with the rear guard of the 1st Division of the US Army, and the US troops had become frightened, and the tank crews abandoned their tanks and fled with the infantry, and 7 tanks were captured by the volunteers.

On the same day, the 1st U.S. Army Division entered Jinxingli, and the U.S. Army lost more than 300 people along the way.

After that, the U.S. troops retreated on the highway under the cover of aircraft and tanks, and the volunteers pursued along the mountains on both sides of the road, and there was no major battle.

December 12:

More than 100,000 men of the US 10th Army began to board ships from the port of Hungnam.

December 15:

The 1st U.S. Army Division began to board ships from the port of Hungnam.

U.S. carrier-based aircraft and naval guns formed a dense firepower network to stop the 27th and 26th armies from attacking.

December 24: The U.S. military blasted and destroyed the remaining supplies and equipment, and left North Korea forever.

Overall, let's take a look at the more prominent Liutanli Battle, located in Changjin Lake, 10 kilometers west of Liutanli is the prelude to the Battle of Changjin Lake, on November 27, 1950, a tragic battle kicked off in Liutanli, guarding Liutanli is the US Army from Kuah Island to Okinawa Island 1st Marine Division, the attacking side is the 79th Division of the 27th Army of the People's Liberation Army Huaye First Division, and its subordinate 235th Regiment is still the famous "Jinan First Regiment".

On November 9, 1950, the 27th Army of the Volunteer Army arrived at Linjiang by train from Andong City, and stopped all the way to distribute cotton clothes, cotton hats and some cotton coats and cotton shoes, due to the urgency of time, ammunition, medical drugs, combat equipment, and food were not replenished, especially one-third of the personnel did not have cotton coats, leather hats, and cotton shoes, and the 79th Division of the 27th Army marched on foot for seven days in the snow at minus 27 degrees Celsius after entering the DPRK, and the road was sparsely populated, the mountains were high and the roads were slippery, and they were also attacked by five air raids, with 15 casualties, for air defense, The soldiers all wore white cotton clothes and marched at night, due to the extension of the transportation line, the 27th Army soon ran out of food, and could only rely on potatoes and soybeans to support, and only arrived in the Lishuiping area on November 17 to assemble, according to the order of the Ninth Corps, the 80th and 81st Divisions of the 27th Army attacked Xinxingli, and the 59th Division, which was good at interspersing, moved back to the south of Liutanli and cut off the retreat of the American army, and the 79th Division, which was good at attacking fortifications, launched three regiments at the same time to attack Liutanli from north to south.

Xiao Jinghai, commander of the 79th Division, ordered the 235th Regiment to first seize the 1348.1282.1241 heights, the 237th Regiment to occupy Xiaodedong Mountain and Southwest Mountain, the 236th Regiment to occupy the 1167 heights, and then cross the river to capture the 1200 and 1100 heights to divide the connection between Liutanli and Xinxingli. The 236th Regiment placed the 3rd Battalion on the left road, After seizing the 1167.1 heights, cross the river by Meixiangli, if the river cannot be crossed, cooperate with the 1st Battalion along the north bank road, the 1st Battalion is arranged south of the school cave, wait for the 235th Regiment to occupy the 1240 Heights before attacking, the 2nd Battalion occupies the 1264.6 Heights with 6 companies and a reinforced platoon as a flank guard, the main force of the battalion serves as the reserve of the regiment, and the 236th Regiment consists of three infantry battalions, 1 heavy mortar company, a manpower transport company, a stretcher company and an animal transport platoon. There were 4 100-mm heavy mortars, 18 heavy machine guns, 9 82-mm mortars, and 27 60-mm mortars.

The regiment should have 3,434 people, but at that time the operation was imminent, and there were only 2,810 people, including 108 people from the regiment headquarters, 80 people from the logistics office, 55 people from the special service company, 166 people from the reconnaissance company, 183 people from the stretcher company, 100 people from the rotation training team, 62 people from the mortar company, 111 people from the artillery company, 42 people from the health team, 46 people from the battalion headquarters of the first battalion, 144 people from the machine gun company, 161 people from the 1st company, 158 people from the 2nd company, 139 people from the 3rd company, 47 people from the battalion headquarters of the second battalion, 150 people from the machine gun company, 156 people from the 4th company, and 148 people from the 5th company. 143 people in 6 companies, 49 people in the battalion headquarters of the third battalion, 144 people in the machine gun company, 137 people in the 7th company, 160 people in the 8th company, 121 people in the 9th company, 1 light machine gun in each infantry squad, 2 submachine guns, one person with bare hands, everyone else has a rifle, each combatant also has 4 grenades, equipped with a base submachine gun, rifle ammunition, 0.5 base light machine gun ammunition, 2.5 base heavy machine gun ammunition, and 1250 tons of ammunition left in Linjiang, because the entire 27th Army only has 20 2-ton trucks, The whole army needs 85 tons of grain a day, and it takes five days to make a round trip to transport it, which is not enough to transport food, let alone ammunition.

Commander of the 1st Marine Division, Oliver. Major General Smith believed that Changjin Lake was not suitable for mechanized American combat, but at MacArthur's urging, on November 24, the vanguard of his 1st Marine Division entered Liutanli. On November 24, the 2nd Battalion of the 7th Regiment of the 1st Marine Division led by Lieutenant Colonel Landford Rockwood first entered Liutanli, and then the regimental commander Colonel Homer Liedsberg led the 1st and 3rd Battalions of the 7th Marine Regiment to arrive successively, and on November 25-27, the 2nd, 1st, and 3rd Battalions of the 5th Marine Regiment also arrived at Liutanli, and at 8:25 a.m. on the 27th, the 3rd Battalion of the 7th Marine Regiment advanced to Wupingli under the command of Lieutenant Colonel Wilmont Harris, occupying Heights 1426 and 1403. Subsequently, the 5th Battalion of the 2nd Marine Regiment was under the command of the battalion commander Haod. Lieutenant Colonel Royce, under the command of Lieutenant Colonel Royce, advanced to the 1271 Heights and met with stubborn resistance. Colonel Liedberg had a bad premonition, although some prisoners confessed that there were 2 Chinese divisions nearby preparing to attack Liutanli.

But Homer. Colonel Lizberg looked at the prisoners' thin clothes, and did not quite believe that the Chinese army could fight in the field at minus 40 degrees Celsius in such clothes. Colonel Leedsberg sent an aerial reconnaissance and ground reconnaissance team, and the aerial reconnaissance found nothing, but the ground reconnaissance team found a large number of Chinese troops in the southwest and north, and after noon, it was also found that the Chinese reconnaissance troops arrived close to Liutanli to reconnoitre, and at 15 o'clock in the afternoon, Colonel Lizberg and the commander of the 5th regiment, Raymond. At this time, the US army had a total of 5 infantry battalions plus 1 infantry company, 1 artillery battalion and 4 artillery batteries, 18 155 mm howitzers, 30 105 mm howitzers and 24 107 mm mortars, and these artillery opened artillery positions southeast of Liutanli, under the unified command of Lieutenant Colonel Harvey Fihan, commander of the 1st Artillery Battalion, and the muzzles of the guns were all pointed to the west and southwest.

Originally, each Marine Regiment also had an anti-tank artillery company with 5 tanks, but the U.S. troops in Liutan did not have a tank that could be used, because the road in Xiajieyuli - Liutanli was simple and there was a thick layer of ice, and the M26 heavy tank might be difficult to pass, so on the 27th, 1 M4A3 tank was sent to explore the road, and the M4A3 tank took three hours to reach Liutanli, and the tank crew returned to Xiayuli by helicopter before dark, preparing to guide 4 M26 tanks through Xiajieyuli on the 28th- Liutanli Highway.

Throughout the Battle of Changjin Lake, the U.S. military lost 4,418 combat personnel and 7,313 frostbite casualties, of which more than 2,500 were killed or missing. The battle report of the Ninth Corps is that more than 7,000 enemies have been annihilated, and the statistical caliber is different, for example, the more than 1,000 US troops scattered in Xinxingli are counted in the number of enemies destroyed, and the US army has already collected this group of people, so naturally it is not counted. The second is that because the volunteers had no food at all, many prisoners were released.

Speaking of food, the 27th and 20th armies were already running out of food while they were still on the march, but the logistics and transportation were very difficult, and the Koreans did not trust the volunteers, and a large number of Koreans fled to the US military camp across the defense line of the volunteers. There are also a small number of North Koreans who take advantage of the fact that the volunteers do not threaten or block the North Koreans, and go back and forth through the defense line of the volunteers to report intelligence to the US military. A large number of North Koreans began to retreat with the US troops in Liutan-ri, and there were about a few thousand people in the Changjin Lake area, and finally a total of more than 90,000 Koreans left with the US troops in Heentam Port. And the 26th Army, which was walking behind, had no food to raise, and many died of starvation.

The Ninth Corps lost more than 14,000 troops in this battle, and more than 30,000 died of frostbite and frostbite, of which more than 4,000 froze to death and more than 7,300 were killed.

Although there were many major mistakes in the preparation and tactical actions of the Ninth Corps during the Battle of Changjin Lake, the Ninth Corps overcame tremendous difficulties and exerted its super will and courage to force the US 1st Army Division and the entire US 10th Army to withdraw from North Korea, which was undoubtedly a great achievement strategically.
