How to evaluate the battle of Changjin Lake?

Let's review the background of the Korean War. In order to unify the Korean peninsula and attack South Korea, North Korea was on the verge of success, but it did not guard against the landing of the US troops in Busan. The deployment was completely disrupted and quickly defeated. All the way out, the American troops are approaching the Yalu River, the border between China and North Korea, which is about to lead the war to China. In this case, Chinese people's Volunteer Army sent troops to North Korea.

About 1 .6,000 troops of Chinese people's Volunteer Army's 9th Corps entered northeast Korea, and unexpectedly surrounded about110,000 troops of the U.S.-led United Nations in the Changjin Lake area of northeast Korea. After that, the U.S. military struggled to break through under the cover of aircraft, and most of them escaped from the encirclement after 1.7 days.

In the battle of Changjin Lake, the 9th Corps of the Volunteers recovered most of the eastern area north of the 38th parallel, completely crushing the strategic intention of the US military to occupy Korea. Since then, the US military has changed from a strategic offensive to a strategic defensive, and has never crossed the 38th parallel. At the Battle of Changjin Lake, the volunteers wiped out the 3 1 regiment of the 7th Infantry Division of the US Army, the so-called "polar bear regiment", and participated in World War II, which dealt a great blow to the arrogance of the US Army.

Volunteers in the battle of Changjin Lake also suffered heavy losses, with a high proportion of frostbite and frostbite, which basically lost the ability to attack again, and also gave the US military the opportunity to repair and realize its defense preparations against South Korea. The Ninth Corps of Volunteers was originally the main force deployed in southern China to prepare for the liberation of Taiwan Province Province. Due to the tight war, it was too late to change summer clothes and winter clothes, so they went into battle in the cold of MINUS 40 degrees, resulting in serious non-combat attrition. The great escape of the US military has also greatly reduced the domestic doubts about sending troops to North Korea, and there has also been a so-called "great escape" within the US military.
