The war that broke out on the Korean Peninsula more than seventy years ago was no stranger to it, a large-scale "no" war in which a newborn country said no to the world's top power, and it was also a war in which hundreds of thousands of soldiers exchanged their lives and blood for the image of a country that has accumulated weakness and poverty for nearly a hundred years. After more than three years of arduous battle, the country finally brought the United States back to the negotiating table and reached a Panmunjom deal.
After the end of the Korean War, an American general said it was the only war that the United States had not won since the eighteenth century. Since then, China in the East has begun to make the world re-evaluate, re-examine and begin to respect it. The profound impact on the later world pattern still exists today.
History continues to roll forward, the war of blood and fire has left us for decades, many stories have been dusted by the years, let us in the attitude of being responsible for history, to restore these histories little by little.
Here I would like to say that I do not like to take any position when telling history, because history exists objectively, and it is an indelible memory in human memory. As a narrator, this is an attitude of impartiality that should be held. At this point, what I admire most is Tai Shi Gong. As for how to judge that period of history, the monarchs are free to play in the comments section.
The Korean War is an absolutely top and absolutely magnificent local war in human history after World War II, and many of the countless stories and countless historical materials in it are gradually being washed away by the waves of history or many have been sealed in the dust. Today's revelations are about the huge role played by a mysterious intelligence unit of the U.S. military in this war.
First, let's introduce the initial situation of the Korean War, on June 25, 1950, the Korean War began to break out, and the North Korean army was full of momentum. When the Syngman Rhee regime was about to collapse, the Americans intervened, because the time was too hasty, and the US army first invested only one division, the US 24th Division, and as a result, the entire army was destroyed, and even the division commander became a prisoner. Subsequently, the U.S. army began to increase its troops on a large scale, but it was still unable to resist the offensive of the Korean People's Army.
By the end of July, the U.S. Eighth Army under the command of General Walker had been surrounded in a square area of only a few tens of square kilometers in Busan, and it was about to be driven out of the sea, and the situation was already very unfavorable to the US army, but General Walker had another advantage, that is, intelligence.
Here we will talk about this protagonist, the US military has an intelligence agency called Sigint, which is the abbreviation of Signal Intelligence, which translates to the meaning of signal intelligence. The main task of this agency is to eavesdrop.
At that time, they listened to North Korea's communications on a large scale and on a large scale, and obtained a lot of important information, including the movement of troops on the other side, logistics and transportation, and the issuance of orders from commanders. This agency informed Walker of all the important information he had heard about the movement of North Korean troops, the deployment of troops, and so on.
Having mastered the precise location of the North Korean main force, Walker used the limited American forces and main firepower to the correct enemy attack area, making the most of the human resources at hand. As a result, the Korean People's Army was frustrated in the final offensive battle, and it has been slow to break through the American defense line.
We all know what happened after that. By the time MacArthur landed at Inchon, the Eighth Army began a surprise attack and rendezvous with MacArthur. The situation in the People's Army was irreparable, and it began to collapse for thousands of miles, and eventually led to the dispatch of Chinese troops, which led to the outbreak of the largest local war of the nineteenth century.
Sigint, an intelligence service, is very powerful, not only monitoring the important information of North Korea, but also listening to the communications between the Chinese volunteers and the North Korean troops, and even in the surveillance, it was found that the North Korean troops were not telegraphs, but the telegraphers made artificial voices, "dit-dot, dit-dit", simulating morse code telegrams, just like singing.
In addition, Sigint oversaw communications from the North Korean, Chinese, and Soviet air forces, as well as conversations between ground and air pilots, and then immediately forwarded them to the U.S. Air Force, greatly increasing the U.S. Air Force's lethal rate of sorties and bombings. Throughout the Korean War, the U.S. Air Force's strike losses against our side were enormous, especially in terms of logistics and transportation, and the logistics were seriously inadequate, which was also a major reason for the serious losses in the Fourth Campaign, which is an undeniable fact.
So that later, Mr. Peng had to let his right-hand man, Hong Xuezhi, deputy commander of the Volunteer Army, take charge of logistics, and Hong Xuezhi never commanded the combat troops again, and he had a lifelong deal with logistics. This has always been a major regret in the life of General Hong Xuezhi.
In fact, historically, the United States has been spying on China since the 1940s, and even then China was still an ally of the United States, americans were not at ease. When Marshall arrived in China, he ordered a surveillance of both the Kuomintang and the Communists in China, but the actions of the Kuomintang in Nanjing were not effective due to the instability of the current, and the monitoring point of our Party was located in Seoul, which may be too far away, and the result is also very bad.

At the same time, the British were not idle, and they were secretly eavesdropping on the communications between Yan'an and the Soviet Union, but they had been hiding from their special allies, the United States, and the British surveillance did not end until March 1946.
After the founding of New China in 1949, the United States set up a special department, the main member of which was a group of Chinese linguists, began to monitor and analyze the civilian telephone and telegrams of Chinese mainland, and also listened to unencrypted government communications, led by Milton Zaslow, the predecessor of Sigint.
For example, soldiers send telegrams to their families saying that they are not going home, that the troops have a mission, or that local food is transported, may also be related to the army. These are military intelligence. It wasn't until the summer of 1950 that they began to spot Chinese troops massing on the Yalu River.
According to their surveillance findings, from May to June, 70,000 troops moved along the Yangtze River to Wuhan, and in July, they reported upward that there were signs that Marshal Lin Biao might be interfering in the situation in North Korea, why did they judge that Lin Biao was the most capable general in China, because as the most capable general in China, they judged that once they entered the war, it would definitely be Marshal Lin Biao who led the troops. Subsequently, they also found a large-scale transportation of troops to the northeast at the railway hubs in central China. By September, the intelligence service had found six field army units gathered in the northeast close to the North Korean border.
On October 21, Sigint reported 20 more troop trains heading northeast from Shanghai, and on November 7, he overheard a phone call from an Eastern European communist in Beijing who said Chinese soldiers could volunteer for war, saying, "We're already at war here." "（we are already at war here）。
That same month, Sigint intercepted an unencrypted telegram asking Shanghai to send 30,000 maps of North Korea to northeastern forces, while also overhearing health authorities asking northeastern troops to start vaccinations, mainly to prevent epidemics in North Korea.
China has clearly entered a state of emergency readiness, and all this intelligence has been handed over to the relevant US departments and personnel, including MacArthur. But on October 15, 1950, when President Truman asked about the possibility of China sending troops, Old Mai still replied contemptuously that there was almost none, and his answer at that time was: very little, meaning that the possibility is very small. In MacArthur's eyes, such a new and weak country would not dare to go to war with our world's number one power. Moreover, this war is through a resolution under the United Nations, and China will not take such a big military and political risk to get involved in this war.
Perhaps MacArthur's analysis has some truth, but MacArthur still underestimated the determination and courage of the Chinese, and after the founding of New China, China is no longer the old China that is oppressed everywhere. On November 26, when 30 Chinese divisions crossed the Yalu River and entered North Korea, MacArthur's arrogance and prejudice left the US side defenseless, which eventually led to the bankruptcy of MacArthur's "Christmas Offensive", the ace main cavalry division was almost completely annihilated, and even General Walker was killed in a car accident during the retreat...
Later, we all know the results, with the subsequent development of the war, finally MacArthur was dismissed, and finally the US military was forced to return to the 38th line, and finally had to sit at the table in Panmunjom...
If MacArthur had taken this information seriously at the time, I am afraid that the war would have been recounted in the history books. In this way, the important information obtained by the Sigint intelligence service was ignored by the arrogant general, and of course, in the end, he also tasted the bitter fruit of his arrogance. But as us, we must also thank him for his arrogance!!!
