American soldiers are notoriously afraid of death in battle. Faced with the daily bloodshed and death of the Korean War, Eisenhower ran for president in 1952 by declaring, "If there must be a war there, let the Asians fight the Asians, and we support the liberal side." At the Battle of Shangganling, Van Vleet, commander of the U.S. 8th Army, was in fact a staunch practitioner of Eisenhower's theory. The Battle of Shangganling lasted for 43 days, first the US 7th Division and the Han 2nd Division took turns to attack; because the American casualties were too large, on the 12th day, the US 7th Division withdrew, the position was taken over by the Han 2nd Division, and later the Han Ninth Division was transferred in. Therefore, the Battle of Shangganling was actually Chinese a fierce tug-of-war with the Koreans.

On October 14, 1952, the U.S. Military "Showdown Operation" began. This bloody calamity in Ganling was one of the most crazy and brutal days in the history of world war, and also created the bloodiest "Van Vliet shelling volume" in history: 105 mm rockets were distributed 55 shells per day, and 155 mm guns were 40 rounds per day. The U.S. War Department stipulates that the former has only 50 rounds and the latter only 30 rounds. In the face of such fierce artillery fire, from time to time a volunteer soldier was shocked to the point that his teeth were broken, his tongue and lips; when he was released, his mouth and hands were full of blood. In the main tunnel of Beishan No. 1, a 17-year-old Sichuanese soldier with a milky voice was shocked to death. Similarly, in a U.S. artillery position on a ground-moving hill, a soldier sitting in a chair was also shocked to death. Survivors recall the scene at that time, and they all use hell to describe the scene at that time, and its horror can be seen from this. It was also on this day that during the Battle of Shangganling against Position 2 of Highland 597.9, The legs of platoon leader Sun Zhanyuan were blown off when he led the entire platoon on a surprise combat mission. Several U.S. troops pounced on him. He pulled out only one grenade and dragged his legs toward the enemy group. The "History of the War to Resist US Aggression and Aid Korea" of the Fifteenth Army described it as follows: "In the Battle of Shangganling, it became a common phenomenon to pull grenades, grenades, explosive canisters, and explosive packs at critical moments and die with the enemy, sacrificing oneself to blow up enemy bunkers, blocking the enemy's gun holes, and so on."
The main attack on the first day was launched by the Thirty-first Regiment of the 7th Division of the U.S. Eighth Army. The army is generally underfloored, and all the units under its jurisdiction are mixed with some officers and men of the ROK army. Of the 3,537 officers and men of the Thirty-first Regiment, there were 238 South Korean officers and men. In 12 days, the U.S. military suffered more than 2,000 casualties. On October 24, the 12th day, Van Vleet instructed James, commander of the U.S. Ninth Army, to cancel the U.S. 7th Division's defense of Hill 598 and replace it with the Han Second Division. On November 1, 1952, the Han Ninth Division came to Shangganling to participate in the battle. The division had blocked the attack of the Eighteenth Army of the Volunteer Army at White Horse Mountain 10 days ago, and the momentum was fierce. At that time, the chief of staff of the Han Ninth Division was Park Geun-hye's father, Park Chung-hee.
In the early days of the Korean War, the Rok and volunteers fled for their lives at the touch of a touch, and the U.S. military scolded them as "these Asians can only run, and when they hear gunshots, they can slip faster than rabbits." After the end of the fifth battle, the two armies confronted each other, and the US army trained all the ROK troops in turn. At the time of arriving at Ganling, the volunteer soldiers found that the two devils were more difficult than the American devils. The continuous artillery fire was like a storm, wreaking havoc endlessly on the land of Ganling on the ground. The United States wondered, how could the Volunteers survive? The first to discover this secret was not the United States, but the Second Division of Han. On October 17, the lieutenant colonel staff officer of han's 2nd Division led people to reconnoiter, only to discover that the volunteers were using tunnels to deal with artillery attacks. With the unique thinking and creation of the Orientals, the Rok army's destruction of the tunnels is more vicious than that of the US army. They used mortars to hoist the mouth of the tunnel, smoked them with gas and sulfur bombs, blocked the openings with boulders, wound barbed wire into balls to block the vents, and chiseled the cannon holes from the top of the tunnels to explode with explosives. The U.S. military was busy for 5 days and could not do anything, while the Rok army blew up tunnel No. 2 nearly 30 meters in just one day, crushing and wounding 8 people. It took 37 volunteer casualties to reopen the opening. Wang Jinshan, acting commander of the Third Corps of the Volunteer Army, once concluded: "Tactically, the US army is rigid, and the puppet army is more flexible, ghostly, and cunning; it can rush to repair fortifications, and is good at stationing troops at the dead corners of the anti-slope and continuously counterattacking us." Many soldiers of the Fifteenth Army of the Volunteer Army felt the same way, saying that the pseudo-Ninth Division had learned to defend with the Thirty-eighth Army at Baima Mountain, and the pseudo-Second Division had learned to attack with the Fifteenth Army at Shangganling.
South Korea's "Korean War" book wrote in a variety of ways, "the defense line of the US Seventh Division was handed over to the ROK Second Division", "at that time, this measure of the corps immediately aroused public opinion, giving people the impression of only reducing the casualties of the US troops." Of course, the U.S. military is afraid of casualties and replaced by South Korea and the volunteer army, but the reason is grandiose, "Don't forget, this is fighting for your own country!" "At that time in South Korea, the US military was the emperor, and even if Syngman Rhee disobeyed, the Americans could dismiss him as president at any time.
It was precisely because of the considerable combat effectiveness shown in the Battle of Shangganling that in the Vietnam War, the United States demanded that South Korea send troops. Since 1965, South Korea has sent army and marine corps to Vietnam to cooperate with the INVASION of the U.S. Army. By the end of the withdrawal in March 1973, a total of 310,000 South Korean soldiers had participated in the Vietnam War, including the Ninth Division. Like the U.S. military, they burn and loot, and they do no evil. When the Korean War came again, it was not difficult to imagine that the South Koreans were still acting as cannon fodder at the forefront. A country that does not even have command of the battlefield expects the Americans to let their sons rush to the front, and they do not dream about it. Once war breaks out, the history of North Koreans fighting Koreans, or "Asians fighting Asians," in ground battles, is bound to repeat itself.
