6. Heroes and Villains of the Cold War: The Korean War: The Cold War Turns Hot (1950–1953)

My Name is Syngman Rhee: President of South Korea

I was born in 1875 in a Korea very different from the nation the world knows today. The Joseon Dynasty still ruled, but Korea was increasingly surrounded by powerful nations seeking influence over our land. China, Japan, and Russia competed around us while many Koreans debated how our country could survive. As a young man, I became convinced that Korea needed political reform, education, national strength, and independence. I did not believe our people could remain isolated while stronger nations determined our future.

Prison Changed My Life

My political activities brought me into conflict with the Korean government, and in 1899 I was imprisoned. I spent years behind bars, but prison did not silence my political ambitions. I studied Christianity, Western political ideas, international affairs, and the English language. My Christian faith became increasingly important to me, and I came to believe that Korea's future required both independence and modernization. When I was released in 1904, I carried with me a stronger determination to make Korea a sovereign nation capable of defending itself.

Fighting for Korea from Abroad

Japan formally annexed Korea in 1910, but I refused to accept that Korea had ceased to be a nation merely because another power occupied it. I spent much of my life abroad advocating Korean independence, especially in the United States. I studied at George Washington University, Harvard, and Princeton, receiving a doctorate from Princeton in 1910. I appealed repeatedly to American leaders and international organizations. I believed Korea's independence was not simply a Korean concern; it was a question of whether powerful nations would permit weaker peoples to govern themselves.

The Republic in Exile

After the March First Movement of 1919, Korean independence activists established the Provisional Government of the Republic of Korea. I became its first president, although disagreements soon divided our movement. Some revolutionaries wanted armed struggle. Others favored diplomacy or socialist revolution. I placed enormous faith in international diplomacy and particularly in gaining American support. My methods created enemies among fellow Korean nationalists, and I was eventually removed from the presidency of the provisional government. Yet I continued campaigning for independence because I remained convinced that Japan would someday be defeated.

Liberation—and Division

Japan's surrender in 1945 should have been the moment when Korea became whole and independent again. Instead, Soviet troops occupied Korea north of the 38th Parallel while American troops occupied the south. I had spent decades fighting foreign domination only to return home and discover that Korea had been divided by the world's great powers. I fiercely opposed communism and believed Soviet influence threatened Korean independence. In 1948, the Republic of Korea was established in the south, and I became its first president.

War Comes to Seoul

On June 25, 1950, North Korean forces crossed the 38th Parallel. Their armies drove south with tanks and artillery, and Seoul fell within days. The Republic appeared close to destruction. Our forces retreated toward the southeastern corner of the peninsula while civilians fled before the advancing armies. Yet South Korea survived. American forces arrived, followed by troops from other nations under the United Nations Command. At the Pusan Perimeter, we held. Then General Douglas MacArthur struck at Inchon, Seoul was retaken, and the North Korean offensive collapsed.

I Wanted a United Korea

I did not believe the war should end by simply restoring the division that had existed before it began. Korea had been one country for centuries, and I wanted it united under the Republic of Korea. UN forces advanced north, but China entered the conflict and drove them back. By 1951, the fighting settled into a terrible stalemate near the 38th Parallel. While diplomats discussed an armistice, I resisted any agreement that permanently accepted Korea's division. When the armistice was signed on July 27, 1953, my government refused to sign it. The shooting largely stopped, but Korea remained divided.

The President I Became

I remained president after the Korean War, but my determination to retain power increasingly damaged the democratic principles I claimed to defend. My government suppressed political opponents, manipulated elections, restricted dissent, and relied heavily upon authoritarian methods. I convinced myself that South Korea faced an existential communist threat and required strong leadership. Yet fear of an enemy does not automatically justify the destruction of political liberty. By 1960, accusations of election fraud helped ignite widespread demonstrations, particularly among students. Their protests became known as the April Revolution, and I resigned the presidency.

One Korea Becomes Two: The 38th Parallel - Told by Syngman Rhee

When Japan surrendered in August 1945, Koreans celebrated the end of thirty-five years of Japanese colonial rule. I had spent decades abroad working for Korean independence, and now the empire that had annexed our country in 1910 had fallen. Yet our liberation contained a bitter surprise. Before Koreans could establish a single independent government, the United States and Soviet Union had already agreed to divide responsibility for accepting the Japanese surrender in Korea. Soviet forces would operate north of the 38th Parallel; American forces would operate south of it. The line was intended as an administrative arrangement. It would become one of the most dangerous borders on Earth.

A Line Drawn Across Our Country

The 38th Parallel did not follow an ancient Korean border. Korea had been politically unified for centuries, and families, roads, farms, and communities suddenly found themselves on opposite sides of a line chosen during the final days of World War II. Soviet troops entered northern Korea in August 1945, while American forces arrived in the south the following month. Neither occupying power originally announced that Korea would remain permanently divided. Plans called for eventual independence, but the growing distrust between Moscow and Washington made agreement over Korea's political future increasingly difficult.

I Returned to a Country in Turmoil

I returned to Korea in October 1945 after decades abroad. Everywhere there was political excitement. Nationalists, communists, conservatives, socialists, moderates, and independence activists all competed to shape the new Korea. I was fiercely anti-communist and believed that Soviet influence in the north threatened our opportunity to create an independent Korean republic. Meanwhile, Soviet authorities supported the rise of communist leaders in their occupation zone, including a young former guerrilla named Kim Il Sung. What had begun as a military occupation was rapidly becoming an ideological division.

Washington and Moscow Cannot Agree

The United States and Soviet Union attempted to negotiate Korea's future through a joint commission, but disagreements over which Korean political organizations should participate helped bring negotiations to a standstill. The conflict was larger than Korea. Across Europe, relations between the former wartime Allies were deteriorating, and the Cold War was taking shape. Korea was becoming another place where two competing visions confronted one another. I increasingly argued that if a unified government could not immediately be established, Koreans in the south should create their own government rather than remain indefinitely under military occupation.

The United Nations Steps In

Unable to reach an agreement with the Soviet Union, the United States brought the Korean question before the United Nations in 1947. The UN called for elections leading toward Korean independence and sent a commission to observe them. Soviet authorities refused to permit the commission to operate in the north. Elections therefore went forward in much of the south on May 10, 1948. They were controversial, and some Koreans opposed holding elections that could formalize the division of the peninsula. Nevertheless, a new National Assembly was elected, and I was chosen to become president.

Two Governments Claim One Korea

On August 15, 1948, the Republic of Korea was formally established in Seoul. I became its first president. But north of the 38th Parallel, another government was taking shape. On September 9, the Democratic People's Republic of Korea was proclaimed under Kim Il Sung. We now had two governments, two armies, and two political systems—but each claimed legitimacy over the entire Korean peninsula. Neither side viewed the division as a satisfactory permanent settlement.

Violence Before the Korean War

It would be a mistake to imagine that Korea remained peaceful until June 1950. Political violence, rebellions, government repression, guerrilla warfare, and border clashes had already killed many Koreans. The Jeju uprising beginning in 1948 and the Yeosu-Suncheon rebellion later that year revealed the depth of political conflict inside the south, and South Korean security forces committed severe abuses during campaigns against suspected insurgents and leftists. Along the 38th Parallel, North and South Korean forces increasingly exchanged fire. By 1949, the border separating us was becoming a battlefield.

My Name is Kim Il Sung: Leader of North Korea

I was born Kim Song-ju in 1912 near Pyongyang, during the Japanese occupation of Korea. My childhood unfolded beneath foreign rule, and my family later moved into Manchuria. Korea had lost its sovereignty, and resistance to Japan became one of the defining forces of my youth. As a young man, I embraced communism and revolutionary nationalism, believing that Korea's liberation would come not through petitions to foreign governments but through organized resistance and armed struggle.

The Guerrilla Fighter

During the 1930s, I joined communist guerrilla forces fighting the Japanese in Manchuria. These years became central to the story I later told about myself and my government. North Korean propaganda would eventually transform my guerrilla career into an enormous revolutionary legend, exaggerating my role and presenting me as the almost singular liberator of Korea. In reality, I was one among many Korean and Chinese anti-Japanese guerrillas. Nevertheless, these experiences gave me military credentials and connections that would become extremely important after World War II.

The Soviets Bring Me Home

By the early 1940s, Japanese military pressure had forced surviving guerrillas like me into the Soviet Union, where I served in a Soviet military unit. Then Japan surrendered in August 1945. Korea was liberated, but it was immediately divided along the 38th Parallel. Soviet troops occupied the north while American troops occupied the south. I returned to Korea with Soviet support, and the Soviets helped elevate me above competing communist leaders. I was young, ambitious, disciplined, and determined to build a revolutionary government in northern Korea.

Building North Korea

In 1948, the Democratic People's Republic of Korea was established, with me as premier. In the south, Syngman Rhee led the Republic of Korea. Both governments claimed to represent all Koreans, and neither considered the division permanent. My government redistributed land, nationalized major industries, expanded the military, and increasingly eliminated political rivals. I wanted Korea reunited, but I intended that reunification to occur under my government. The question became whether it would happen through politics or through war.

I Chose War

By 1950, I believed the time had come to destroy the southern government and reunify Korea by force. I sought support from Joseph Stalin and consulted with Mao Zedong's communist government in China. On June 25, 1950, North Korean forces crossed the 38th Parallel. Our troops captured Seoul within days and drove South Korean forces rapidly southward. For a moment, victory appeared close. I believed the southern government would collapse and that the peninsula could quickly be brought under my control.

The War Turns Against Me

I had underestimated the international response. The United States intervened under the United Nations Command, and additional nations sent forces to defend South Korea. North Korean troops pushed their enemies into the Pusan Perimeter, but they could not finish them. Then General Douglas MacArthur launched the amphibious landing at Inchon in September 1950. The operation cut our supply lines and shattered our offensive. Seoul was lost, our armies retreated northward, and UN forces crossed the 38th Parallel. Soon they were approaching the Chinese border, and my government itself appeared threatened with destruction.

China Changes the War

Communist China would not tolerate an American-led army approaching the Yalu River. Chinese forces entered Korea in enormous numbers during late 1950 under commanders including Peng Dehuai. Their offensives drove UN forces southward and saved my government from collapse. Seoul changed hands again, and eventually the front stabilized near the 38th Parallel. What I had expected to be a rapid war of reunification became three years of destruction. Korean cities were devastated, families were divided, and enormous numbers of soldiers and civilians were killed, wounded, displaced, or missing.

A Divided Korea Remained

An armistice was signed on July 27, 1953. Korea remained divided roughly where it had been before the war. I survived politically, but I had failed to reunify the peninsula. In the decades that followed, I consolidated increasingly absolute power. Political opponents disappeared through purges, imprisonment, exile, and execution. My government developed the ideology later associated with Juche, emphasizing political independence and national self-reliance, while an enormous personality cult presented me as the father and protector of the nation.

The State I Left Behind

I ruled North Korea until my death in 1994, and power ultimately passed to my son Kim Jong Il, establishing a hereditary political system within a state that called itself revolutionary and socialist. For decades, I portrayed my decisions as necessary for independence, unity, and resistance against foreign domination. Yet at the end of my story, one fact cannot be hidden behind revolutionary speeches: I chose to pursue reunification through invasion in 1950, and Koreans on both sides paid an extraordinary price. I sought to create a powerful and united Korea, but I helped leave behind a peninsula divided by armies, fortified borders, political repression, and memories of a war whose consequences continue long after my death.

Kim Il Sung's Gamble: Preparing to Reunify Korea by Force - Told by Kim Il Sung

By 1949, Korea had become a nation divided against itself. I governed the Democratic People's Republic of Korea in the north, while Syngman Rhee governed the Republic of Korea in the south. Both governments claimed the right to rule the entire peninsula, and neither accepted the 38th Parallel as Korea's rightful permanent border. I was determined that Korea would be reunited under my government. The question was no longer whether I wanted reunification. The question was whether I could convince the communist powers surrounding me that military victory was possible.

I Needed Stalin's Approval

The Soviet Union had helped establish my government and had supplied North Korea with military equipment and training, so I could not simply begin a major war without considering Moscow. I repeatedly sought Joseph Stalin's approval for an attack on South Korea. At first, Stalin resisted. He feared provoking a direct confrontation with the United States, and he was not convinced that my forces could win quickly. By early 1950, however, circumstances had changed. The Soviet Union had successfully tested an atomic bomb in 1949, and Mao Zedong's Communists had defeated Chiang Kai-shek's Nationalists on the Chinese mainland. To Stalin, the balance of power in Asia appeared to be shifting.

The Signals from America

Events in the United States also influenced our calculations. In January 1950, U.S. Secretary of State Dean Acheson publicly described America's defensive perimeter in the Pacific without explicitly including South Korea. This did not mean Washington had promised to abandon South Korea, and historians caution against treating the speech as an invitation to invade. Yet from Pyongyang and Moscow, American intentions were being studied closely. Most American occupation troops had already withdrawn from South Korea in 1949. I increasingly believed that if we moved rapidly enough, the southern government could collapse before the United States could decisively intervene.

Stalin Finally Says Yes

In early 1950, Stalin gave conditional approval for my plan, but he made clear that Soviet troops would not fight the war for me. He also expected me to consult Mao. I traveled to Moscow and then secured Chinese support for the undertaking. Mao had his own concerns, but China had just emerged from years of civil war, and thousands of ethnic Korean veterans who had fought with Chinese Communist forces returned to North Korea. I now possessed something Syngman Rhee badly lacked: a substantial army with combat experience and Soviet-supplied heavy weapons.

Building an Army for the Attack

The Korean People's Army was strengthened with Soviet T-34/85 tanks, artillery, aircraft, trucks, and other equipment. Soviet advisers helped train and organize our forces. South Korea's military, by comparison, possessed no comparable tank force and was primarily organized for internal security and limited defensive operations. I expected speed to decide the struggle. If our armored columns could smash through South Korean defenses, seize Seoul, and destroy organized resistance, I believed the government in the south might collapse before outside powers could reverse the situation.

The Dangerous Assumption

Our strategy depended upon more than military superiority. I believed many South Koreans would oppose Rhee's government and that an invasion might encourage uprisings in the south. There was genuine political unrest and insurgency there, but I badly overestimated how much support an invading northern army would receive. I also underestimated the possibility that the United States would respond with overwhelming military power. These assumptions were critical because my plan depended upon a short war. A prolonged international conflict was not what I intended to begin.

The Border Becomes a Fuse

Throughout 1949 and into 1950, clashes along the 38th Parallel demonstrated how unstable Korea had become. Both northern and southern forces participated in border fighting, and leaders on both sides spoke aggressively about reunification. But what I was preparing was something far greater than another border engagement. North Korean divisions were positioned for a coordinated offensive designed to break through South Korean defenses and drive rapidly toward Seoul. Tanks and artillery would give our attacking troops an advantage that the South Korean army was poorly equipped to meet.

June 1950: The Gamble Begins

By June 1950, I believed the opportunity had arrived. Stalin had approved the operation under specific conditions, China had been consulted, and the Korean People's Army appeared stronger than its opponent. Before dawn on June 25, North Korean forces launched a massive attack across the 38th Parallel. I expected a rapid campaign that would reunify Korea under my government. At first, events seemed to prove me correct. South Korean defenses broke, our tanks raced south, and Seoul stood directly in our path. But my greatest gamble rested upon one assumption that would soon prove disastrously wrong: that Korea's war could remain Korea's war.

June 25, 1950: North Korea Invades - Told by Kim Il Sung

Before dawn that Sunday morning, the uneasy border dividing Korea erupted into war. The Korean People's Army launched a large, coordinated offensive across the 38th Parallel against South Korea. Artillery opened fire, infantry divisions advanced, and Soviet-built T-34/85 tanks rolled south. My government publicly claimed that the South had attacked first and that our forces were responding, but the historical evidence establishes that North Korea initiated the large-scale invasion. I had committed my government to a tremendous gamble: destroy the Republic of Korea quickly and reunify the peninsula under northern rule before outside powers could stop us.

Our Tanks Break Through

The South Korean army was not prepared to meet the force we sent against it. Its soldiers possessed rifles, machine guns, mortars, and some artillery, but South Korea had no comparable tank force and lacked the heavy equipment necessary to stop our T-34s effectively. North Korean forces broke through at several points and drove rapidly toward Seoul. Some South Korean units fought stubbornly, but confusion spread as communications failed and commanders struggled to understand the scale of the attack. The speed of our advance seemed to confirm my belief that the South could be defeated quickly.

Seoul Stands in Our Path

Seoul lay only about 30 miles south of the 38th Parallel, making the South Korean capital dangerously exposed. President Syngman Rhee's government faced the possibility of capture within days. Refugees crowded roads and bridges as civilians attempted to escape the approaching fighting. South Korean troops withdrew toward the Han River while North Korean forces closed upon the city. The invasion was no longer a border conflict. One of Asia's largest cities was about to become a battlefield.

Seoul Falls

On June 28, only three days after the invasion began, North Korean forces captured Seoul. During the retreat, South Korean forces destroyed the main Han River bridge while many civilians and military personnel were still trying to escape, causing significant casualties and trapping some forces north of the river. For my government, Seoul's capture appeared to be a tremendous victory. Yet something I had expected did not happen on the scale I anticipated. The South Korean state did not simply collapse, nor did the population rise en masse to welcome my forces. The surviving South Korean army continued retreating and fighting.

The United Nations Responds

While our armies moved south, the conflict was becoming international. The United Nations Security Council condemned the North Korean attack and called for the withdrawal of northern forces. The Soviet Union was boycotting Security Council meetings over the question of China's representation and therefore was not present to veto the resolutions. President Harry Truman ordered American air and naval forces to assist South Korea and soon committed ground forces. What I had planned as a Korean war of reunification was rapidly becoming a confrontation with the United States and a United Nations coalition.

The Americans Arrive

American ground troops were rushed from occupation duty in Japan to Korea. On July 5, Task Force Smith met North Korean forces near Osan. The inexperienced and lightly equipped American unit was defeated and forced to withdraw. Other American and South Korean units were pushed south as well. From my headquarters, the battlefield still appeared favorable. Our army had taken Seoul, defeated forces sent against it, and was advancing deeper into the peninsula. But each mile south also stretched our supply lines farther from North Korea.

The Drive Toward Pusan

Through July and early August, North Korean forces continued pushing the defenders toward southeastern Korea. Taejon fell after heavy fighting, and American commander Major General William F. Dean was eventually captured. The surviving South Korean and UN forces withdrew toward an area surrounding the vital port of Pusan. We had conquered most of South Korea in a matter of weeks. On a map, victory seemed almost complete. Yet the defenders now possessed something they had lacked in June: a shortened defensive line supported by an enormous flow of American troops, weapons, aircraft, and supplies arriving through Pusan.

Victory Was Not Yet Victory

I had begun the invasion believing speed would determine everything. In the opening weeks, my army achieved extraordinary territorial gains, but territory alone did not end the war. South Korea survived, the United States intervened, and the United Nations organized a multinational military command against us. Our soldiers had raced almost the entire length of the peninsula, but they had failed to destroy the enemy. By August 1950, North Korean forces stood before the Pusan Perimeter. If we could break it, South Korea might still fall. If we could not, the time we had lost would allow an increasingly powerful enemy to prepare its answer.

My Name is Douglas MacArthur: United Nations Commander

I was born in 1880 into a military family. My father, Arthur MacArthur Jr., had earned the Medal of Honor during the Civil War and later served in the Philippines. The Army was therefore not merely a profession in my household; it was a tradition of duty. I entered the United States Military Academy at West Point and graduated first in my class in 1903. From the beginning, I believed that command demanded confidence, preparation, and the willingness to accept responsibility when others hesitated.

Learning War on the Battlefield

I served during World War I with the 42nd "Rainbow" Division in France. I experienced the violence of modern warfare firsthand and was decorated repeatedly for courage and leadership. After the war, I became superintendent of West Point and later rose to become Chief of Staff of the United States Army. I was never content simply to preserve old military traditions. Warfare was changing, and an army that refused to change with it risked paying for that stubbornness with the lives of its soldiers.

The Philippines and a Promise

Before World War II, I helped organize the defense of the Philippines. When Japan attacked in 1941, American and Filipino forces fought desperately, but we were overwhelmed. President Franklin Roosevelt ordered me to leave for Australia. I departed reluctantly, declaring, "I shall return." Those words became a promise. In 1944, American forces landed at Leyte, and I returned to Philippine soil. By 1945, Japan was defeated, and I stood aboard the USS Missouri as Japan formally surrendered.

Rebuilding a Former Enemy

After the war, I became Supreme Commander for the Allied Powers in occupied Japan. Victory alone was not enough; peace had to be built upon it. Under the occupation, Japan underwent enormous political and social changes, including a new constitution, democratic reforms, expanded rights for women, and restructuring of institutions associated with militarism. I had commanded armies against Japan, but now my responsibility was to help transform a defeated enemy into a stable nation capable of taking its place in a peaceful international order.

War Erupts in Korea

On June 25, 1950, North Korean forces invaded South Korea. Seoul fell, and South Korean and American troops were driven toward the Pusan Perimeter. I was given command of United Nations forces. The situation appeared desperate, but war is often decided when one commander sees opportunity where others see only danger. I proposed an amphibious assault at Inchon, far behind North Korean lines. Many considered the plan too risky. I believed precisely that risk would make surprise possible.

The Triumph at Inchon

On September 15, 1950, our forces landed at Inchon. The operation succeeded spectacularly. North Korean supply lines were severed, Seoul was recaptured, and enemy forces that had nearly conquered South Korea were driven north. We crossed the 38th Parallel and advanced into North Korea. Pyongyang fell, and our forces moved toward the Yalu River. It appeared possible that Korea might finally be reunited. Yet another army was waiting beyond the frontier.

China Enters the War

Chinese forces entered Korea in enormous numbers during late 1950 and struck our advancing armies. The battlefield changed almost overnight. UN forces retreated south, and Seoul was lost again before eventually being recaptured. I believed the conflict could not be successfully fought while the enemy enjoyed protected bases and supply routes beyond Korea's borders. I argued for broader military measures against Communist China. My superiors in Washington feared that such actions could widen the conflict and perhaps bring the Soviet Union directly into the war.

The President and the General

My disagreement with President Harry Truman became increasingly public. Under the American Constitution, however, generals command armies while elected civilian leaders determine national policy. In April 1951, President Truman relieved me of command. I returned to the United States for the first time in many years and addressed Congress. I reminded them of an old soldiers' ballad: "Old soldiers never die; they just fade away." My military career had ended, but the debate surrounding Korea, limited war, and presidential authority continued.

The World Responds: The United Nations Goes to War - Told by MacArthur

On June 25, 1950, North Korean forces crossed the 38th Parallel in a massive invasion of South Korea. From my headquarters in Tokyo, where I served as Supreme Commander for the Allied Powers in Japan, I watched reports arrive describing South Korean defenses collapsing before North Korean tanks and artillery. Seoul was threatened almost immediately. This was no longer one of the political confrontations that had characterized the early Cold War. An organized army had crossed an international dividing line, and the question confronting the world was whether that advance would be resisted.

The United Nations Acts

The United Nations Security Council moved rapidly. On June 25, it condemned the North Korean invasion and called for the withdrawal of North Korean forces. Two days later, it recommended that UN members assist South Korea in repelling the attack. The Soviet Union could have vetoed these resolutions, but its representative was boycotting the Security Council because the Chinese seat at the United Nations remained held by the Nationalist government based on Taiwan rather than Mao Zedong's People's Republic of China. Moscow's empty chair became one of the remarkable circumstances that allowed the United Nations response to move forward.

America Enters the Fight

President Harry Truman concluded that the United States could not allow South Korea to be conquered. American air and naval forces were ordered into action, followed by ground troops. Truman and his advisers saw Korea within the larger struggle against communist expansion, although the Soviet Union and Communist China had their own interests and calculations. American leaders also remembered the failures of the 1930s, when aggression had often been met with hesitation. This time, Washington intended to demonstrate that armed expansion would carry consequences.

I See the Battlefield

On June 29, I flew from Japan to Korea to examine the situation personally. I traveled near the front and saw refugees streaming south while exhausted South Korean soldiers attempted to slow the enemy. The North Korean army possessed Soviet-built T-34 tanks that South Korean forces were poorly equipped to stop. I concluded that airpower and supplies alone would not save the Republic of Korea. Ground troops would be required. Soon American soldiers stationed in Japan were being rushed into a war for which many had received little preparation.

The First Americans Meet the Enemy

On July 5, Task Force Smith confronted North Korean forces near Osan. These American soldiers were intended to delay the enemy, but they discovered quickly that determination could not substitute for adequate weapons and preparation. Their anti-tank weapons proved largely ineffective against the North Korean T-34s, and the unit was forced to retreat after suffering significant losses. More American forces arrived, but they too were pushed backward. Taejon fell later in July. We were learning, at great cost, that the enemy could not simply be frightened into stopping because American troops had appeared.

A United Nations Command

On July 7, the Security Council recommended that participating forces be placed under a unified command led by the United States. President Truman appointed me commander of the United Nations Command. Although Americans would provide most of the forces, equipment, and logistical support, this was not an American effort alone. South Koreans carried an enormous share of the fighting, while Britain, Canada, Australia, Turkey, France, the Philippines, Thailand, New Zealand, and other nations contributed combat forces or support. Eventually, personnel from more than twenty countries would assist the UN effort in military or medical roles.

Driven Toward Pusan

Despite this international response, the battlefield continued moving south. North Korean forces had momentum, experienced troops, and heavy equipment. Our forces surrendered mile after mile of territory while attempting to buy time. By August, UN and South Korean troops had been pushed into a defensive region surrounding the southeastern port of Pusan. Behind us lay the sea. Before us stood an enemy that believed victory was almost complete. If Pusan fell, organized resistance in South Korea could become extraordinarily difficult.

The World Had Drawn Its Line

Yet the North Koreans had failed to accomplish one essential objective: they had not destroyed us before reinforcements arrived. Through Pusan came soldiers, tanks, artillery, ammunition, food, and equipment. Above the battlefield, UN aircraft increasingly controlled the skies. The defensive perimeter grew stronger while North Korean supply lines stretched farther down the peninsula. Kim Il Sung had expected to settle Korea's future through a rapid invasion. Instead, his attack had brought an international coalition into the war. We had been driven nearly to the edge of Korea, but we were still standing—and I was already considering how an army trapped against the sea might suddenly strike hundreds of miles behind its enemy.

The Pusan Perimeter: South Korea's Fight for Survival - Told by Syngman Rhee

By August 1950, my Republic of Korea appeared to be disappearing beneath the advance of the North Korean army. Seoul had fallen, our forces had retreated repeatedly, and cities we had governed only weeks earlier were now occupied by the enemy. South Korean and American troops withdrew into the southeastern corner of the peninsula around the vital port of Pusan, today called Busan. Behind this defensive line lay the sea. If the perimeter collapsed, there was little Korean territory left into which we could retreat.

A Defensive Wall Around Pusan

The Pusan Perimeter stretched roughly 140 miles around an area protected partly by the Naktong River and difficult mountainous terrain. General Walton Walker commanded the U.S. Eighth Army and made clear that further retreat could not continue indefinitely. South Korean troops defended large portions of the line alongside American forces. The North Koreans attacked repeatedly, searching for a place where they could break through, cross the Naktong, and destroy our remaining defenses. The battles around places such as the Naktong Bulge, Taegu, and the approaches to Masan became desperate struggles for survival.

The Port That Kept Us Alive

Pusan was more than a city. It was the logistical doorway through which our survival arrived. Ships unloaded American soldiers, tanks, artillery, ammunition, fuel, food, and medical supplies. Railroads and roads carried those resources toward the front. The longer we held the perimeter, the stronger the United Nations forces became. The North Korean army faced the opposite problem. Its troops had advanced hundreds of miles from their original bases, and UN aircraft attacked roads, bridges, vehicles, and supply routes behind them. The rapid advance that had brought Kim Il Sung's forces close to victory was now creating serious logistical difficulties.

Our Soldiers Paid the Price

Maps cannot adequately describe what those weeks meant to the soldiers defending South Korea. Units sometimes lost positions during the day and counterattacked to regain them. South Korean troops, many poorly equipped during the opening stages of the invasion, fought beside increasingly powerful American formations. Thousands were killed or wounded. Yet every day that our armies continued fighting gave the United Nations Command more time to reinforce the perimeter. North Korea needed a breakthrough quickly. We needed only to prevent one.

Civilians Caught Between Armies

Behind the battlefront came another army—refugees. Families carried children, food, blankets, and whatever possessions they could manage as they fled south. Pusan's population swelled dramatically. The war also produced terrible violence against civilians. Communist forces carried out killings of some prisoners and civilians, while South Korean authorities and security forces committed mass killings of suspected communists and political prisoners during the wider retreat, including atrocities associated with the Bodo League massacres. Fear of infiltrators added to the chaos. The struggle for South Korea's survival was accompanied by suffering that cannot be reduced to a simple story of heroes on one side and villains on the other.

The North Koreans Try to Break Us

In late August and September, North Korean forces launched another major effort against the perimeter. Fighting erupted across several sectors as they attempted to overwhelm our defenses before additional UN strength could arrive. They achieved dangerous penetrations, but they could not turn them into a decisive collapse. Their soldiers were exhausted, replacements were increasingly inexperienced, and supplies were becoming harder to move south. Meanwhile, UN artillery, armor, aircraft, and reinforcements were accumulating behind our lines.

Something Was Coming

By early September, we had survived the most dangerous weeks of the war. But General Douglas MacArthur was not satisfied with merely holding Pusan. While North Korea concentrated much of its army against us in the southeast, MacArthur prepared an extraordinary amphibious operation far behind their lines at Inchon, near Seoul. If it failed, the consequences could be disastrous. If it succeeded, the North Korean army attacking the Pusan Perimeter could suddenly find its supply routes threatened and enemy forces behind it.

South Korea Survives

For weeks, the Pusan Perimeter had looked like the final corner of a dying republic. Instead, it became the place where North Korea's advance was stopped. Our soldiers and their UN allies had endured long enough for reinforcements to arrive and for MacArthur to prepare his counterstroke. On September 15, 1950, while North Korean troops still faced us around Pusan, UN forces began landing at Inchon. The war that had driven us relentlessly south was about to reverse direction with astonishing speed.

Inchon: MacArthur's Great Gamble - Told by Douglas MacArthur

By August 1950, the war map looked disastrous. North Korean forces had captured Seoul and driven South Korean and American troops into the Pusan Perimeter in the southeastern corner of Korea. Yet I saw opportunity in the enemy's success. Their army had raced hundreds of miles south, stretching its supply lines behind it. Rather than continue throwing men directly against the strongest part of their advance, I proposed striking far behind them. My target was Inchon, the port serving the approaches to Seoul.

Why Inchon Seemed Impossible

My officers had good reasons to question the plan. Inchon possessed extreme tides, narrow approach channels, dangerous mudflats, strong currents, seawalls, and limited beaches. Timing would have to be extraordinarily precise. Naval planners warned that the geography made an amphibious assault extremely difficult. I understood their objections, but I saw those difficulties as part of the opportunity. If our own commanders considered Inchon nearly impossible, the North Koreans might consider it unlikely as well. Surprise could accomplish what brute force could not.

I Defend the Gamble

On August 23, senior Army, Navy, and Marine Corps officers gathered in Tokyo to discuss the operation. For hours, the difficulties were laid before me. I listened and then defended the plan. Inchon offered access to Seoul and, more importantly, placed us near critical North Korean communications and supply routes. A successful landing could force the enemy to fight in two directions while UN forces broke out of the Pusan Perimeter. The operation was approved. It received the name Operation Chromite.

September 15, 1950

Before dawn on September 15, naval guns and aircraft struck enemy positions around Inchon. The assault began with Marines attacking Wolmi-do, an island guarding the harbor. They captured it rapidly. Because of Inchon's tides, the main landing forces then had to wait for the water to rise again before approaching the seawalls later that day. Marines climbed ladders over the barriers under combat conditions and established their positions ashore. The dangerous harbor that had frightened our planners became the doorway through which we entered behind the North Korean army.

The Trap Begins to Close

The strategic effect was soon apparent. North Korean commanders had concentrated much of their strength against the Pusan Perimeter, leaving fewer troops to meet our landing near Seoul. Once Inchon was secured, X Corps advanced inland. At the same time, General Walton Walker's Eighth Army began breaking out from Pusan. North Korean forces suddenly faced pressure from the southeast and from troops operating near their communications routes in the northwest. An army that had spent months advancing was now threatened with being cut off.

The Battle for Seoul

I wanted Seoul recaptured quickly. The city was South Korea's capital and possessed enormous political significance, but taking it was not easy. North Korean troops established defenses, and Marines and other UN forces fought through difficult urban combat. Civilians were again caught amid the destruction. On September 29, after fierce fighting, Seoul was formally returned to President Syngman Rhee. Only weeks earlier, the Republic of Korea had appeared close to extinction. Now its flag again flew over its capital.

North Korea's Army Collapses

Meanwhile, UN and South Korean forces surged out of the Pusan Perimeter. North Korean units retreated northward, and many soldiers were killed, captured, scattered, or forced to abandon heavy equipment. Operation Chromite had achieved what I hoped: it disrupted the enemy's rear and helped transform the entire campaign. By the end of September, the immediate invasion of South Korea had been defeated. But success presented us with a new and much more dangerous question. Should we stop at the 38th Parallel?

Victory Creates a Greater Gamble

Inchon became the operation most closely associated with my command in Korea. It demonstrated the value of surprise, maneuver, and calculated risk. Yet victory can tempt commanders and governments to believe that yesterday's success guarantees tomorrow's. We had saved South Korea and shattered much of Kim Il Sung's invading army. Now the road into North Korea appeared open. I believed we had an opportunity to destroy the remaining enemy forces and reunify Korea. Beyond North Korea, however, stood Communist China—and the next gamble would prove far more dangerous than the landing at Inchon.

From Defending South Korea to Invading North Korea - Told by MacArthur

By the end of September 1950, the army that had nearly conquered South Korea was retreating. Our landing at Inchon had helped break the North Korean offensive, Seoul had been recaptured, and UN and South Korean forces were advancing northward. We had entered the war to repel an invasion. Now we faced a far greater decision: should we stop at the 38th Parallel, or cross it and attempt to destroy Kim Il Sung's regime?

Why Stop at an Artificial Line?

The 38th Parallel was not an ancient Korean frontier. It had been selected in 1945 as the dividing line for accepting the Japanese surrender and had hardened into a political boundary between North and South. From a military perspective, allowing the shattered North Korean army to escape northward meant giving it an opportunity to rebuild. From a political perspective, crossing the line offered the possibility of creating one Korea. Washington authorized operations north of the parallel, subject to important restrictions intended to avoid provoking Soviet or Chinese intervention.

The Advance Into North Korea

South Korean troops crossed the 38th Parallel on October 1, 1950, followed by other UN forces. The campaign moved rapidly. North Korean units had suffered devastating losses, and organized resistance weakened in many areas. On October 19, UN forces captured Pyongyang, the North Korean capital. Kim Il Sung's government retreated farther north. Only months earlier his armies had stood near Pusan. Now his own capital had fallen, and it seemed possible that the Korean War might end with the destruction of his regime.

Warnings From China

But beyond Korea's northern frontier stood the People's Republic of China. Chinese leaders had repeatedly warned that they would not simply watch American-led forces approach their border. Zhou Enlai publicly communicated warnings in early October that China would intervene if American troops crossed the 38th Parallel. Washington knew intervention was possible, but uncertainty remained over whether Beijing would actually commit its forces. I believed China was unlikely to enter the war on a scale capable of defeating us. That judgment would soon be tested.

Toward the Yalu River

Our forces continued advancing toward the Yalu River, which formed much of the boundary between Korea and China. The terrain became increasingly difficult as units moved through mountains and along separated roads. Our armies were also becoming geographically divided. The Eighth Army advanced through western Korea while X Corps operated farther east. I expected North Korean resistance to collapse and hoped the troops might finish the campaign before winter fully arrived. To many of us, victory appeared close enough to touch.

An Enemy We Could Not See

Unknown to many soldiers moving north, Chinese troops were already crossing the Yalu. Beginning in October, forces of the Chinese People's Volunteers entered Korea secretly under Peng Dehuai. They moved largely at night and concealed themselves during daylight, reducing their exposure to UN aircraft. Chinese units struck UN and South Korean troops in late October and early November, then pulled back. Their sudden appearance should have made the danger unmistakable, but the size and intentions of the Chinese intervention remained uncertain.

The Home-by-Christmas Offensive

In late November, we resumed a major advance that became associated with the expectation that the war might soon be finished. The objective was to destroy remaining enemy forces and reach positions near the northern frontier. Instead, the mountains concealed an enormous surprise. Chinese forces launched powerful attacks beginning on November 25 against the Eighth Army and soon struck X Corps in northeastern Korea. Units that had been advancing toward what seemed like final victory suddenly found themselves fighting for survival.

Victory Turns Into Retreat

The Chinese intervention transformed the Korean War. UN forces withdrew southward under tremendous pressure, and the fighting around places such as the Chosin Reservoir became legendary for its brutality and winter conditions. Our advance across the 38th Parallel had nearly destroyed North Korea, but it had also brought our armies close enough to China's border to trigger the intervention Beijing had warned about. We had crossed into North Korea believing we might end the war. Instead, by the closing weeks of 1950, we faced a new enemy, a much larger war, and one of the most dangerous retreats in American military history.

My Name is Peng Dehuai: Commander of Chinese Forces in Korea

I was born in 1898 in Hunan Province, China, into a poor farming family. Hunger and hardship were not theories to me; they were companions of childhood. I worked from a young age and saw how easily ordinary people could be crushed by poverty, landlords, corrupt officials, and war. China itself was divided and weak, torn between competing armies and political movements. I came to believe that strength required discipline and that a soldier's duty was not merely to speak about suffering but to act.

Becoming a Soldier

I entered military life as a young man and eventually became involved in the revolutionary struggles transforming China. In 1928, I joined the Chinese Communist Party and led troops who became part of the Red Army. I fought through the bitter conflicts between Communist and Nationalist forces and participated in the Long March. There was little glory in those years. Men marched hungry, wounded, and exhausted. Armies survive not because slogans are beautiful, but because soldiers endure when conditions tell them to surrender.

War Against Japan

When Japan's invasion threatened China, our struggle became part of a greater war for national survival. I became one of the senior Communist commanders fighting Japanese forces and helped direct the Hundred Regiments Offensive in 1940, a major Communist military campaign against Japanese positions and transportation networks. The operation demonstrated our ability to strike the enemy, but it also brought severe Japanese retaliation. War taught me repeatedly that every military decision carries a price, and that price is often paid by soldiers and civilians far from the headquarters where orders are written.

Victory in China's Civil War

After Japan's defeat in 1945, civil war resumed between the Communists and Chiang Kai-shek's Nationalists. I commanded Communist armies in northwestern China through difficult campaigns against Nationalist forces. By 1949, the Communist armies had won control of mainland China, and Mao Zedong proclaimed the People's Republic of China. We had fought for decades to reach that moment. Yet almost immediately, another war began beyond China's northeastern frontier.

The Americans Approach the Yalu

The Korean War began in June 1950 when North Korea invaded South Korea. At first, North Korean armies advanced rapidly, but American-led United Nations forces counterattacked at Inchon and drove north. Soon they crossed the 38th Parallel and approached the Yalu River, directly along China's border. Chinese leaders feared that hostile forces positioned there would threaten our newly established government. Mao decided that China would intervene. I was selected to command what we called the Chinese People's Volunteers.

Into Korea

We crossed into Korea secretly in October 1950. Our soldiers traveled largely at night, concealed themselves during daylight, and carried limited supplies through difficult mountains. We faced an enemy with enormous advantages in aircraft, artillery, vehicles, and logistics. I therefore relied upon surprise, movement, infiltration, and concentrated attacks. Beginning in late October and especially in November, our offensives struck UN forces and forced them into a major retreat. Battles around the Chosin Reservoir and elsewhere demonstrated that China had entered the war in force.

Driving South

Our armies pushed the UN forces back across much of Korea, and Seoul fell again in January 1951. But victory was not as simple as advancing on a map. Our supply lines were stretched, American airpower attacked roads and transportation routes, and our soldiers suffered terribly from hunger, exhaustion, wounds, and winter cold. UN forces reorganized and counterattacked. Seoul changed hands once more, and by the middle of 1951 the front stabilized near the 38th Parallel. Neither side could easily destroy the other without paying an enormous price.

A War of Hills and Trenches

The conflict became a grinding struggle over hills, ridges, bunkers, and trenches. Negotiations began while soldiers continued dying. Arguments over territory and prisoners of war prolonged the talks for two years. I believed China had demonstrated that it would defend its borders and would not retreat simply because its opponent possessed greater technology. Yet the battlefield had also shown the terrible limitations of modern war. On July 27, 1953, an armistice finally stopped most of the fighting. Korea remained divided.

I Challenged Mao

After Korea, I became China's minister of national defense. But I was never a man who found silence comfortable when I believed something was wrong. During the Great Leap Forward, I saw reports of unrealistic production claims, economic disruption, and terrible hardship in the countryside. In 1959, I wrote privately to Mao criticizing serious problems with the campaign. Mao interpreted my criticism as a political challenge. I was removed from power and replaced as defense minister.

My Final Battle

During the Cultural Revolution, I was persecuted, publicly humiliated, imprisoned, and repeatedly interrogated. My health deteriorated, and I died in 1974. I had spent much of my life believing discipline, sacrifice, and military strength could protect ordinary people and strengthen China. Only at the end must I admit the harder lesson: loyalty to a nation cannot mean silence when its leaders are wrong.

China Enters the War: Peng Dehuai and the Great Counterattack - Told by Dehuai

By October 1950, the Korean War had moved dangerously close to China. North Korea's invasion had been shattered after the UN landing at Inchon, and American-led forces crossed the 38th Parallel and advanced north. Pyongyang fell on October 19. Ahead of them lay the Yalu River and, beyond it, Chinese territory. Mao Zedong and other Chinese leaders feared that if North Korea collapsed, American forces could stand directly along our northeastern frontier. The question in Beijing became severe: should a country only one year removed from decades of war send its soldiers into another conflict?

Mao Orders Intervention

The decision was enormously risky. China's civil war had only recently ended on the mainland, our economy was exhausted, and the United States possessed overwhelming advantages in aircraft, naval power, vehicles, artillery, and supplies. Soviet assistance was available but more limited than some Chinese leaders had hoped. Mao nevertheless decided to intervene. Our troops entered Korea under the name Chinese People's Volunteers, a designation intended in part to limit the appearance of a formal war between China and the United States. I was given command. If we failed, the consequences for the new People's Republic could be disastrous.

We Cross the Yalu

Beginning in October, Chinese forces crossed the Yalu River into Korea. Secrecy became one of our greatest weapons. Our troops frequently marched at night and concealed themselves during daylight because UN aircraft dominated the skies. We moved through mountains carrying supplies by foot, pack animal, and whatever transportation survived enemy air attacks. Conditions were severe. Food was limited, winter approached, and many soldiers lacked adequate protection from the cold. Yet our objective depended upon surprise. MacArthur's forces had to believe that the road north remained open.

The First Blow

Our first major attacks began in late October. Chinese forces struck South Korean and UN units, including around Unsan, where American and South Korean troops encountered an enemy they had not expected in such strength. After several engagements, I pulled much of my force back into concealment. This created uncertainty among UN commanders. Had China intervened with only limited forces? Were these merely volunteers protecting the border? The uncertainty worked to our advantage. UN forces soon resumed their advance northward.

MacArthur Comes Toward Us

In November, MacArthur launched a major offensive intended to finish the war. His forces were spread across difficult terrain, with the U.S. Eighth Army operating in western Korea and X Corps farther east. Mountains and distance separated units that might otherwise have supported one another. I intended to exploit those weaknesses. We did not need to match American firepower weapon for weapon. We would use concealment, infiltration, night attacks, and concentrated manpower to strike isolated formations where their technological superiority could not be used as effectively.

The Great Counterattack

On November 25, Chinese forces attacked the Eighth Army in western Korea. Days later, another enormous battle erupted in the northeast around the Chosin Reservoir. UN troops suddenly discovered that the enemy they thought had withdrawn was present in great strength. Chinese units attacked through mountains and bitter cold, sometimes infiltrating between defensive positions at night. The Eighth Army began a major retreat, while U.S. Marines and other UN troops around Chosin fought their way toward the coast under extraordinarily difficult conditions.

The Cost of Driving Them South

We had achieved strategic surprise, but victory carried a terrible price. Chinese soldiers suffered heavily from American artillery and airpower, and the winter itself became an enemy. Frostbite devastated units, and shortages of food, ammunition, clothing, and medical supplies followed us throughout the campaign. Our soldiers could move through mountains that vehicles found difficult, but every mile south stretched our primitive supply system farther. The Americans were retreating, but their armies were not destroyed.

Seoul Falls Again

Chinese and North Korean forces continued south across the 38th Parallel. In January 1951, Seoul fell for the second time during the war. Only weeks earlier UN troops had been approaching the Chinese frontier; now they were withdrawing deep into South Korea. It appeared that we had reversed MacArthur's great advance. But I understood what the battlefield was telling us. Our troops were exhausted, while the UN forces were reorganizing and bringing their enormous firepower to bear. We could drive them backward, but destroying them was another matter entirely.

A Different War Begins

The intervention of China saved Kim Il Sung's government from likely destruction and transformed the Korean War again. North Korea had begun the conflict expecting a rapid victory. MacArthur had later believed the North might be defeated and Korea reunited under the South. Now China had prevented that outcome, but we had not conquered South Korea either. By 1951, the front would begin settling again near the very region where the war had started. We had entered Korea to prevent an enemy army from reaching China's border. We succeeded in driving it back—but we had also entered a war from which there would be no quick escape.

MacArthur vs. Civilian Authority: How Far Did America Go? - Told by MacArthur

By early 1951, the Korean War had become something I found deeply troubling: a war in which American soldiers were expected to fight and die while political leaders deliberately limited how the conflict could be fought. Chinese intervention had driven our forces back from northern Korea, and Seoul had fallen again before being recaptured in March. I believed we faced a fundamental military question. If Communist China was supplying armies that attacked us in Korea, how could we defeat those armies while refusing to strike important sources of their power beyond the Korean border?

Washington Feared a Larger War

President Harry Truman and his advisers saw the problem differently. Their principal objective was no longer the complete destruction of communist power in Korea but preventing South Korea from being conquered while avoiding a wider war with China or the Soviet Union. The Soviet Union possessed atomic weapons, Europe remained the central concern of American Cold War strategy, and Washington feared that expanding the conflict into China might trigger Soviet intervention or even another world war. To Truman, Korea had become a limited war fought for limited objectives.

I Wanted Greater Freedom to Fight

I argued for stronger measures against Communist China. Among the possibilities I supported were bombing certain Chinese military targets and bases beyond Korea, imposing a naval blockade of China's coast, and expanding the use of Nationalist Chinese forces from Taiwan against the Communist government. I believed restrictions gave the enemy advantages it did not deserve. Yet some proposals discussed during this period, including possible use of atomic weapons, were far more dangerous. I believed military pressure could force the enemy to reconsider the war; Washington feared those same actions might transform Korea into World War III.

Wake Island and Growing Disagreement

President Truman and I met at Wake Island in October 1950, before China's massive intervention had fully transformed the war. At that time, I expressed confidence that large-scale Chinese intervention was unlikely. That judgment proved seriously mistaken. After China entered the conflict, disagreements between Washington and my headquarters became increasingly difficult to contain. I remained convinced that commanders in the field needed sufficient freedom to defeat the forces confronting them. The administration increasingly believed my public statements were interfering with national policy.

The General Speaks Publicly

The conflict reached a critical point in March 1951. The Truman administration was considering ways to pursue negotiations, while I publicly issued a statement challenging the Chinese commander to recognize the military strength available to the United Nations and warning that the conflict could be expanded. Then Republican House Minority Leader Joseph Martin released a letter I had written to him in which I criticized important aspects of administration policy. My words were now openly contradicting the strategy established by the president and his civilian advisers.

Who Commands the General?

This dispute was no longer simply about battlefield tactics. The Constitution makes the president commander in chief, and America's military operates under civilian authority. A general may advise, argue privately, and warn his superiors, but the final decision about national policy belongs to elected civilian leaders. President Truman concluded that my public opposition made continued command impossible. On April 11, 1951, he relieved me of my commands and replaced me in Korea with General Matthew Ridgway.

I Return to America

I returned to the United States to an extraordinary public reception. Crowds greeted me, and on April 19 I addressed a joint meeting of Congress. I defended my conduct and my belief that there could be no substitute for victory. At the end, I recalled the old barracks ballad: "Old soldiers never die; they just fade away." For many Americans, I became the symbol of a commander prevented from winning. For others, Truman had defended one of the most important principles of the American republic.

The Harder Meaning of Command

I never ceased believing that Communist China should have faced greater military pressure. Yet the controversy taught a lesson larger than the career of any general. Military commanders possess expertise in war, but they do not alone decide what risks a nation will accept or what political objectives its wars will pursue. I had commanded armies across the Pacific and had accepted the surrender of Japan, but those achievements did not place me above civilian authority. A republic entrusts tremendous power to its generals—and therefore requires those generals, even when they profoundly disagree, to remember exactly who commands them.

Stalemate, Armistice, and a War That Never Officially Ended (1951–1953) - Told by Peng Dehuai & Syngman Rhee

The Front Stops Moving

Syngman Rhee: Stalemate, Armistice, and a War That Never Officially Ended (1951–1953) - Told by Peng Dehuai & Syngman Rhee. By the summer of 1951, the Korean War had changed again. Seoul had changed hands four times, armies had surged from one end of Korea to the other, and enormous numbers of soldiers and civilians had suffered. Yet neither side had achieved reunification. United Nations and South Korean forces had pushed your armies back from their deepest advance into the South, Peng, while Chinese and North Korean forces had prevented us from destroying the northern government. The battlefront settled near the 38th Parallel, remarkably close to where this terrible war had begun.

Peng Dehuai: You are correct that neither army could easily destroy the other, but do not mistake stalemate for peace. Our forces constructed trenches, bunkers, tunnels, and defensive positions across the mountains. The war began to resemble the positional warfare of an earlier generation. Instead of racing hundreds of miles across Korea, soldiers now fought for individual hills and ridges. Artillery thundered across narrow stretches of ground, patrols entered enemy territory at night, and men died capturing positions that sometimes changed hands repeatedly.

Negotiating While Fighting

Syngman Rhee: Peace negotiations began in July 1951, first at Kaesong and later at Panmunjom. To an outsider, negotiations might have suggested that the war was nearly over. They were wrong. The talks continued for approximately two years while soldiers continued fighting. Negotiators argued about where the ceasefire line should be located, how an armistice would be supervised, and what should happen to prisoners of war. Every delay meant that men were still being killed while diplomats sat across a table discussing how to stop the killing.

Peng Dehuai: The prisoner question became especially difficult. The Communist side initially insisted upon the repatriation of prisoners, while the United Nations Command argued that prisoners should not be forcibly returned if they refused. Many Chinese and North Korean prisoners said they did not want to return to communist-controlled territory. To us, allowing prisoners to choose appeared politically unacceptable and raised fears about coercion and propaganda inside the camps. The disagreement helped prevent an armistice long after the front itself had largely stabilized.

The Battle for the Hills

Syngman Rhee: While negotiations dragged on, soldiers fought battles whose names would become symbols of the stalemate: Heartbreak Ridge, Bloody Ridge, Old Baldy, and later Pork Chop Hill. These were not meaningless fights to the men ordered to take them. Hills could provide observation points, strengthen defensive positions, or influence negotiations over the final line. Yet the territorial gains were often painfully small. Korea was being measured in yards while lives were being spent by the thousands.

Peng Dehuai: And our soldiers paid heavily as well. American and UN forces possessed tremendous artillery and airpower. Chinese troops responded by constructing extensive tunnel systems and fortified positions in the hills. We learned to survive beneath the earth and emerge to fight. Neither side possessed an easy path to victory. The battlefield itself was demonstrating what politicians were slowly accepting: completely conquering the opposing Korea might require an escalation whose human and international consequences could become far greater than either side was prepared to accept.

Rhee Refuses to Accept Division

Syngman Rhee: That was precisely what I found unacceptable. I had spent my life demanding an independent and united Korea. Now foreign governments were negotiating an agreement that would leave my country divided. I opposed an armistice that did not produce reunification. In June 1953, my government released more than 25,000 anti-communist North Korean prisoners who did not wish to return north. The action infuriated the Communist negotiators and angered our American allies. I wanted the world to understand that South Korea would not willingly approve a settlement that made division permanent.

Peng Dehuai: Your action threatened negotiations that had already consumed two years. Yet by 1953, powerful forces were pushing toward an agreement. Joseph Stalin had died in March, and the Soviet leadership became more willing to see the Korean conflict concluded. The prisoner issue was eventually addressed through arrangements allowing prisoners unwilling to return home to be transferred temporarily to neutral supervision. The remaining obstacles could finally be overcome.

July 27, 1953

Peng Dehuai: On July 27, representatives of the Korean People's Army, the Chinese People's Volunteers, and the United Nations Command signed the Korean Armistice Agreement at Panmunjom. I signed for the Chinese People's Volunteers separately afterward. The agreement established a military demarcation line and created a Demilitarized Zone roughly 2.5 miles wide separating the opposing forces. The guns were ordered to fall silent. After more than three years of war, large-scale combat finally stopped.

Syngman Rhee: But I did not sign it. The Republic of Korea was not a signatory to the armistice because I opposed leaving Korea divided. The agreement was a military ceasefire, not a peace treaty. Millions of Koreans had been killed, wounded, or displaced; cities and villages had been devastated; families had been separated; and yet the political question that had helped produce the conflict remained unresolved.

A War Without a Peace Treaty

Peng Dehuai: We began with armies racing across a peninsula and ended almost where the fighting had started. North Korea survived. South Korea survived. China demonstrated that it would intervene when it believed its frontier was threatened, while the United States demonstrated that it would fight to prevent South Korea's destruction. The war also strengthened the military dimension of the Cold War throughout Asia and beyond.

Syngman Rhee: And Korea remained divided. The DMZ became one of the world's most heavily fortified frontiers, separating people who shared centuries of history, language, and culture. The Republic of Korea and North Korea followed radically different paths after 1953, but the Korean War never received the final peace treaty that formally ended it. That is perhaps the strangest conclusion to our story: the shooting largely stopped on July 27, 1953, but the war ended only with an armistice. More than seven decades later, the unresolved division of Korea remains one of the most enduring consequences of the Cold War.
