"United Nations Army"! As the name suggests, this is the earliest multinational armed force established under the united Nations, this armed force was first used in the Korean Peninsula, the first war encountered a powerful opponent, the first time the division encountered setbacks, and its first commander-in-chief was also dismissed because of the unfavorable war and fierce rhetoric that eventually touched the interests of the president.
New to North Korea
However, when the "United Nations Army" just entered the Korean battlefield, especially after the successful landing at Inchon, it was victorious and pressing step by step, and soon reached the Yalu River, looking at the expression of MacArthur Nalezi, commander-in-chief of the "United Nations Army" in the picture below, we knew that at this time in his heart, the "United Nations Army" was invincible!
These photographs taken on the ships of the Navy were taken after only mild resistance and a successful landing on the day of the landing, when MacArthur and the admirals were smiling.
On June 25, 1950, the Korean War broke out, and on September 15, under the command of MacArthur, the "United Nations Army" carried out the world-renowned Inchon Landing Operation on the west coast of the central Korean Peninsula, and the success of this landing undoubtedly became another peak of MacArthur's military career. The landing forces also changed the korean people's army's unstoppable front in the early stages of the war, and the situation on the peninsula was reversed, and soon Seoul was declared recovered on September 25.
Invincible United Nations forces
When this well-equipped, well-trained, and concerted force was on the road to occupyIng Seoul, crossing the "38th Line," and capturing Pyongyang, it seemed that there was no force that could stop their victorious march except for a smooth sailing and victory over the unable to resist the Korean People's Army, and the "United Nations Army" of this period was invincible.
For MacArthur, who was very happy, the end of the yalu river war seemed to be in sight, but in this person's mind, if the war was crossed across the Yalu River, it would be necessary, if it could.
In the memoirs of The second commander of the United Nations Army, Ridgway, wrote several times that MacArthur had a persistent will to lead the war to the west bank of the Yalu River, and this attitude was even more so after the volunteer army entered Korea.
"He has repeatedly advised the Joint Meeting of Chiefs of Staff not to tie his hands and feet, so that he can send the Far East Air Force to bomb air bases, industrial bases, and army concentrations in the northeast of our country, and even blockade our coast, so that the Korean War can be won completely. He even proposed that nuclear weapons be used against our country in order to achieve final victory. (See "Memoirs of Ridgway - Thirty-eighth Parallel North")
Serious mistakes by the intelligence services
However, as the UN forces approached the Yalu River, unexpected things also appeared, and They thought that China, which would not intervene, began to challenge the authority of the UN army. The U.S. Far East Intelligence Service had vowed that China would not intervene on a large scale in 1950, and that if it had been limited to covert support to North Korea. (See Korean War – Wang Shuzeng)
This conclusion ultimately misled MacArthur and harmed the entire United Nations army. As a result, a group of troops dressed in korean people's army uniforms suddenly appeared in the road of the "United Nations Army" march, but shouted that they would not kill with guns. In the mouths of General Walker, commander of the U.S. Eighth Army, this is a new and well-organized, well-trained enemy, and among them is the Chinese army! In the end, the United Nations army also stopped at the banks of the Yalu River
