The korean war 101: causes, course, and conclusion of the conflict.

North Korea attacked South Korea on June 25, 1950, igniting the Korean War. Cold War assumptions governed the immediate reaction of US leaders, who instantly concluded that Soviet Premier Joseph Stalin had ordered the invasion as the first step in his plan for world conquest. “Communism,” President Harry S. Truman argued later in his memoirs, “was acting in Korea just as [Adolf] Hitler, [Benito] Mussolini, and the Japanese had acted ten, fifteen, and twenty years earlier.” If North Korea’s aggression went “unchallenged, the world was certain to be plunged into another world war.” This 1930s history lesson prevented Truman from recognizing that the origins of this conflict dated to at least the start of World War II, when Korea was a colony of Japan. Liberation in August 1945 led to division and a predictable war because the US and the Soviet Union would not allow the Korean people to decide their own future.

Before 1941, the US had no vital interests in Korea and was largely indifferent to its fate.

Before 1941, the US had no vital interests in Korea and was largely in- different to its fate. But after Pearl Harbor, President Franklin D. Roosevelt and his advisors acknowledged at once the importance of this strategic peninsula for peace in Asia, advocating a postwar trusteeship to achieve Korea’s independence. Late in 1943, Roosevelt joined British Prime Minister Winston Churchill and Chinese Generalissimo Chiang Kaishek in signing the Cairo Declaration, stating that the Allies “are determined that in due course Korea shall become free and independent.” At the Yalta Conference in early 1945, Stalin endorsed a four-power trusteeship in Korea. When Harry S. Truman became president after Roosevelt’s death in April 1945, however, Soviet expansion in Eastern Europe had begun to alarm US leaders. An atomic attack on Japan, Truman thought, would preempt Soviet entry into the Pacific War and allow unilateral American occupation of Korea. His gamble failed. On August 8, Stalin declared war on Japan and sent the Red Army into Korea. Only Stalin’s acceptance of Truman’s eleventh-hour proposal to divide the peninsula into So- viet and American zones of military occupation at the thirty-eighth parallel saved Korea from unification under Communist rule.

Deterioration of Soviet-American relations in Europe meant that neither side was willing to acquiesce in any agreement in Korea that might strengthen its adversary.

US military occupation of southern Korea began on September 8, 1945. With very little preparation, Washing- ton redeployed the XXIV Corps under the command of Lieutenant General John R. Hodge from Okinawa to Korea. US occupation officials, ignorant of Korea’s history and culture, quickly had trouble maintaining order because al- most all Koreans wanted immediate in- dependence. It did not help that they followed the Japanese model in establishing an authoritarian US military government. Also, American occupation officials relied on wealthy land- lords and businessmen who could speak English for advice. Many of these citizens were former Japanese collaborators and had little interest in ordinary Koreans’ reform demands. Meanwhile, Soviet military forces in northern Korea, after initial acts of rape, looting, and petty crime, implemented policies to win popular support. Working with local people’s committees and indigenous Communists, Soviet officials enacted sweeping political, social, and economic changes. They also expropriated and punished landlords and collaborators, who fled southward and added to rising distress in the US zone. Simultaneously, the Soviets ignored US requests to coordinate occupation policies and allow free traffic across the parallel.

Deterioration of Soviet-American relations in Europe meant that neither side was willing to acquiesce in any agreement in Korea that might strengthen its adversary. This became clear when the US and the Soviet Union tried to implement a revived trusteeship plan after the Moscow Conference in December 1945. Eighteen months of intermittent bilateral negotiations in Korea failed to reach agreement on a representative group of Koreans to form a provisional government, primarily because Moscow refused to consult with anti-Communist politicians opposed to trustee- ship. Meanwhile, political instability and economic deterioration in southern Korea persisted, causing Hodge to urge withdrawal. Postwar US demobilization that brought steady reductions in defense spending fueled pressure for disengagement. In September 1947, the Joint Chiefs of Staff (JCS) added weight to the withdrawal argument when they advised that Korea held no strategic significance. With Communist power growing in China, however, the Truman administration was unwilling to abandon southern Korea precipitously, fearing domestic criticism from Republicans and damage to US credibility abroad.

Seeking an answer to its dilemma, the US referred the Korean dispute to the United Nations, which passed a resolution late in 1947 calling for internationally supervised elections for a government to rule a united Korea. Truman and his advisors knew the Soviets would refuse to cooper- ate. Discarding all hope for early reunification, US policy by then had shifted to creating a separate South Korea, able to defend itself. Bowing to US pressure, the United Nations supervised and certified as valid obviously undemocratic elections in the south alone in May 1948, which resulted in formation of the Republic of Korea (ROK) in August. The Soviet Union responded in kind, sponsoring the creation of the Democratic People’s Re- public of Korea (DPRK) in September. There now were two Koreas, with President Syngman Rhee installing a repressive, dictatorial, and anti-Communist regime in the south, while wartime guerrilla leader Kim Il Sung imposed the totalitarian Stalinist model for political, economic, and social development on the north. A UN resolution then called for Soviet-American withdrawal. In December 1948, the Soviet Union, in response to the DPRK’s request, removed its forces from North Korea.

South Korea’s new government immediately faced violent opposition, climaxing in October 1948 with the Yosu-Sunchon Rebellion. Despite plans to leave the south by the end of 1948, Truman delayed military withdrawal until June 29, 1949. By then, he had approved National Security Council (NSC) Paper 8/2, undertaking a commitment to train, equip, and supply an ROK security force capable of maintaining internal order and deterring a DPRK attack. In spring 1949, US military advisors supervised a dramatic improvement in ROK army fighting abilities. They were so successful that militant South Korean officers began to initiate assaults northward across the thirty-eighth parallel that summer. These attacks ignited major border clashes with North Korean forces. A kind of war was already underway on the peninsula when the conventional phase of Korea’s conflict began on June 25, 1950. Fears that Rhee might initiate an offensive to achieve reunification explain why the Truman administration limited ROK military capabilities, withholding tanks, heavy artillery, and warplanes.

Pursuing qualified containment in Korea, Truman asked Congress for three-year funding of economic aid to the ROK in June 1949. To build sup- port for its approval, on January 12, 1950, Secretary of State Dean G. Ache- son’s speech to the National Press Club depicted an optimistic future for South Korea. Six months later, critics charged that his exclusion of the ROK from the US “defensive perimeter” gave the Communists a “green light” to launch an invasion. However, Soviet documents have established that Acheson’s words had almost no impact on Communist invasion planning. Moreover, by June 1950, the US policy of containment in Korea through economic means appeared to be experiencing marked success. The ROK had acted vigorously to control spiraling inflation, and Rhee’s opponents won legislative control in May elections. As important, the ROK army virtually eliminated guerrilla activities, threatening internal order in South Korea, causing the Truman administration to propose a sizeable military aid increase. Now optimistic about the ROK’s prospects for survival, Washington wanted to deter a conventional attack from the north.

Stalin worried about South Korea’s threat to North Korea’s survival. Throughout 1949, he consistently refused to approve Kim Il Sung’s persistent requests to authorize an attack on the ROK. Communist victory in China in fall 1949 pressured Stalin to show his support for a similar Korean outcome. In January 1950, he and Kim discussed plans for an invasion in Moscow, but the Soviet dictator was not ready to give final consent. How- ever, he did authorize a major expansion of the DPRK’s military capabilities. At an April meeting, Kim Il Sung persuaded Stalin that a military victory would be quick and easy because of southern guerilla support and an anticipated popular uprising against Rhee’s regime. Still fearing US military intervention, Stalin informed Kim that he could invade only if Mao Zedong approved. During May, Kim Il Sung went to Beijing to gain the consent of the People’s Republic of China (PRC). Significantly, Mao also voiced concern that the Americans would defend the ROK but gave his reluctant approval as well. Kim Il Sung’s patrons had joined in approving his reckless decision for war.

On the morning of June 25, 1950, the Korean People’s Army (KPA) launched its military offensive to conquer South Korea. Rather than immediately committing ground troops, Truman’s first action was to approve referral of the matter to the UN Security Council because he hoped the ROK military could defend itself with primarily indirect US assistance. The UN Security Council’s first resolution called on North Korea to accept a cease- fire and withdraw, but the KPA continued its advance. On June 27, a second resolution requested that member nations provide support for the ROK’s defense. Two days later, Truman, still optimistic that a total commitment was avoidable, agreed in a press conference with a newsman’s description of the conflict as a “police action.” His actions reflected an existing policy that sought to block Communist expansion in Asia without using US military power, thereby avoiding increases in defense spending. But early on June 30, he reluctantly sent US ground troops to Korea after General Douglas MacArthur, US Occupation commander in Japan, advised that failure to do so meant certain Communist destruction of the ROK.

Kim Il Sung’s patrons [Stalin and Mao] had joined in approving his reckless decision for war.

On July 7, 1950, the UN Security Council created the United Nations Command (UNC) and called on Truman to appoint a UNC commander. The president immediately named MacArthur, who was required to submit periodic reports to the United Nations on war developments. The ad- ministration blocked formation of a UN committee that would have direct access to the UNC commander, instead adopting a procedure whereby MacArthur received instructions from and reported to the JCS. Fifteen members joined the US in defending the ROK, but 90 percent of forces were South Korean and American with the US providing weapons, equipment, and logistical support. Despite these American commitments, UNC forces initially suffered a string of defeats. By July 20, the KPA shattered five US battalions as it advanced one hundred miles south of Seoul, the ROK capital. Soon, UNC forces finally stopped the KPA at the Pusan Perimeter, a rectangular area in the southeast corner of the peninsula.

On September 11, 1950, Truman had approved NSC-81, a plan to cross the thirty-eighth parallel and forcibly reunify Korea

Despite the UNC’s desperate situation during July, MacArthur developed plans for a counteroffensive in coordination with an amphibious landing behind enemy lines allowing him to “compose and unite” Korea. State Department officials began to lobby for forcible reunification once the UNC assumed the offensive, arguing that the US should destroy the KPA and hold free elections for a government to rule a united Korea. The JCS had grave doubts about the wisdom of landing at the port of Inchon, twenty miles west of Seoul, because of narrow access, high tides, and sea- walls, but the September 15 operation was a spectacular success. It allowed the US Eighth Army to break out of the Pusan Perimeter and advance north to unite with the X Corps, liberating Seoul two weeks later and sending the KPA scurrying back into North Korea. A month earlier, the administration had abandoned its initial war aim of merely restoring the status quo. On September 11, 1950, Truman had approved NSC-81, a plan to cross the thirty-eighth parallel and forcibly reunify Korea.

Invading the DPRK was an incredible blunder that transformed a three-month war into one lasting three years. US leaders had realized that extension of hostilities risked Soviet or Chinese entry, and therefore, NSC- 81 included the precaution that only Korean units would move into the most northern provinces. On October 2, PRC Foreign Minister Zhou Enlai warned the Indian ambassador that China would intervene in Korea if US forces crossed the parallel, but US officials thought he was bluffing. The UNC offensive began on October 7, after UN passage of a resolution authorizing MacArthur to “ensure conditions of stability throughout Korea.” At a meeting at Wake Island on October 15, MacArthur assured Truman that China would not enter the war, but Mao already had decided to intervene after concluding that Beijing could not tolerate US challenges to its regional credibility. He also wanted to repay the DPRK for sending thou- sands of soldiers to fight in the Chinese civil war. On August 5, Mao instructed his northeastern military district commander to prepare for operations in Korea in the first ten days of September. China’s dictator then muted those associates opposing intervention.

On October 19, units of the Chinese People’s Volunteers (CPV) under the command of General Peng Dehuai crossed the Yalu River. Five days later, MacArthur ordered an offensive to China’s border with US forces in the vanguard. When the JCS questioned this violation of NSC-81, MacArthur replied that he had discussed this action with Truman on Wake Island. Having been wrong in doubting Inchon, the JCS remained silent this time. Nor did MacArthur’s superiors object when he chose to retain a divided command. Even after the first clash between UNC and CPV troops on October 26, the general remained supremely confident. One week later, the Chinese sharply attacked advancing UNC and ROK forces. In response, MacArthur ordered air strikes on Yalu bridges without seeking Washing- ton’s approval. Upon learning this, the JCS prohibited the assaults, pending Truman’s approval. MacArthur then asked that US pilots receive permission for “hot pursuit” of enemy aircraft fleeing into Manchuria. He was infuriated upon learning that the British were advancing a UN proposal to halt the UNC offensive well short of the Yalu to avert war with China, viewing the measure as appeasement.

On November 24, MacArthur launched his “Home-by-Christmas Offensive.” The next day, the CPV counterattacked en masse, sending UNC forces into a chaotic retreat southward and causing the Truman administration immediately to consider pursuing a Korean cease-fire. In several public pronouncements, MacArthur blamed setbacks not on himself but on unwise command limitations. In response, Truman approved a directive to US officials that State Department approval was required for any comments about the war. Later that month, MacArthur submitted a four- step “Plan for Victory” to defeat the Communists—a naval blockade of China’s coast, authorization to bombard military installations in Manchuria, deployment of Chiang Kai-shek Nationalist forces in Korea, and launching of an attack on mainland China from Taiwan. The JCS, despite later denials, considered implementing these actions before receiving favorable battlefield reports.

Early in 1951, Lieutenant General Matthew B. Ridgway, new commander of the US Eighth Army, halted the Communist southern advance. Soon, UNC counterattacks restored battle lines north of the thirty-eighth parallel. In March, MacArthur, frustrated by Washington’s refusal to escalate the war, issued a demand for immediate surrender to the Communists that sabotaged a planned cease-fire initiative. Truman reprimanded but did not recall the general. On April 5, House Republican Minority Leader Joseph W. Martin Jr. read MacArthur’s letter in Congress, once again criticizing the administration’s efforts to limit the war. Truman later argued that this was the “last straw.” On April 11, with the unanimous support of top advisors, the president fired MacArthur, justifying his action as a defense of the constitutional principle of civilian control over the military, but another consideration may have exerted even greater influence on Truman. The JCS had been monitoring a Communist military buildup in East Asia and thought a trusted UNC commander should have standing authority to retaliate against Soviet or Chinese escalation, including the use of nuclear weapons that they had deployed to forward Pacific bases. Truman and his advisors, as well as US allies, distrusted MacArthur, fearing that he might provoke an incident to widen the war.

MacArthur’s recall ignited a firestorm of public criticism against both Truman and the war. The general returned to tickertape parades and, on April 19, 1951, he delivered a televised address before a joint session of Congress, defending his actions and making this now-famous assertion: “In war there is no substitute for victory.” During Senate joint committee hearings on his firing in May, MacArthur denied that he was guilty of in- subordination. General Omar N. Bradley, the JCS chair, made the administration’s case, arguing that enacting MacArthur’s proposals would lead to “the wrong war, at the wrong place, at the wrong time, and with the wrong enemy.” Meanwhile, in April, the Communists launched the first of two major offensives in a final effort to force the UNC off the peninsula. When May ended, the CPV and KPA had suffered huge losses, and a UNC counteroffensive then restored the front north of the parallel, persuading Beijing and Pyongyang, as was already the case in Washington, that pursuit of a cease-fire was necessary. The belligerents agreed to open truce negotiations on July 10 at Kaesong, a neutral site that the Communists deceitfully occupied on the eve of the first session.

North Korea and China created an acrimonious atmosphere with at- tempts at the outset to score propaganda points, but the UNC raised the first major roadblock with its proposal for a demilitarized zone extending deep into North Korea. More important, after the talks moved to Panmunjom in October, there was rapid progress in resolving almost all is- sues, including establishment of a demilitarized zone along the battle lines, truce enforcement inspection procedures, and a postwar political conference to discuss withdrawal of foreign troops and reunification. An armistice could have been concluded ten months after talks began had the negotiators not deadlocked over the disposition of prisoners of war (POWs). Rejecting the UNC proposal for non-forcible repatriation, the Communists demanded adherence to the Geneva Convention that required return of all POWs. Beijing and Pyongyang were guilty of hypocrisy regarding this matter because they were subjecting UNC prisoners to unspeakable mistreatment and indoctrination.

On April 11, with the unanimous support of top advisors, the presi- dent fired MacArthur.

Truman ordered that the UNC delegation assume an inflexible stand against returning Communist prisoners to China and North Korea against their will. “We will not buy an armistice,” he insisted, “by turning over human beings for slaughter or slavery.” Although Truman unquestionably believed in the moral rightness of his position, he was not unaware of the propaganda value derived from Communist prisoners defecting to the “free world.” His advisors, however, withheld evidence from him that contradicted this assessment. A vast majority of North Korean POWs were actually South Koreans who either joined voluntarily or were impressed into the KPA. Thousands of Chinese POWs were Nationalist soldiers trapped in China at the end of the civil war, who now had the chance to escape to Taiwan. Chinese Nationalist guards at UNC POW camps used terrorist “re-education” tactics to compel prisoners to refuse repatriation; resisters risked beatings or death, and repatriates were even tattooed with anti- Communist slogans.

In November 1952, angry Americans elected Dwight D. Eisenhower president, in large part because they expected him to end what had be- come the very unpopular “Mr. Truman’s War.” Fulfilling a campaign pledge, the former general visited Korea early in December, concluding that further ground attacks would be futile. Simultaneously, the UN General Assembly called for a neutral commission to resolve the dispute over POW repatriation. Instead of embracing the plan, Eisenhower, after taking office in January 1953, seriously considered threatening a nuclear attack on China to force a settlement. Signaling his new resolve, Eisenhower announced on February 2 that he was ordering removal of the US Seventh Fleet from the Taiwan Strait, implying endorsement for a Nationalist assault on the mainland. What influenced China more was the devastating impact of the war. By summer 1952, the PRC faced huge domestic economic problems and likely decided to make peace once Truman left office. Major food shortages and physical devastation persuaded Pyongyang to favor an armistice even earlier.

An armistice ended fighting in Korea on July 27, 1953.

Early in 1953, China and North Korea were prepared to resume the truce negotiations, but the Communists preferred that the Americans make the first move. That came on February 22 when the UNC, repeating a Red Cross proposal, suggested exchanging sick and wounded prisoners. At this key moment, Stalin died on March 5. Rather than dissuading the PRC and the DPRK as Stalin had done, his successors encouraged them to act on their desire for peace. On March 28, the Communist side accepted the UNC proposal. Two days later, Zhou Enlai publicly proposed transfer of prisoners rejecting repatriation to a neutral state. On April 20, Operation Little Switch, the exchange of sick and wounded prisoners, began, and six days later, negotiations resumed at Panmunjom. Sharp disagreement followed over the final details of the truce agreement. Eisenhower insisted later that the PRC accepted US terms after Secretary of State John Foster Dulles informed India’s prime minister in May that without progress toward a truce, the US would terminate the existing limitations on its conduct of the war. No documentary evidence has of yet surfaced to support his assertion.

Also, by early 1953, both Washington and Beijing clearly wanted an armistice, having tired of the economic burdens, military losses, political and military constraints, worries about an expanded war, and pressure from allies and the world community to end the stalemated conflict. A steady stream of wartime issues threatened to inflict irrevocable damage on US relations with its allies in Western Europe and nonaligned members of the United Nations. Indeed, in May 1953, US bombing of North Korea’s dams and irrigation system ignited an outburst of world criticism. Later that month and early in June, the CPV staged powerful attacks against ROK defensive positions. Far from being intimidated, Beijing thus displayed its continuing resolve, using military means to persuade its adversary to make concessions on the final terms. Before the belligerents could sign the agreement, Rhee tried to torpedo the impending truce when he released 27,000 North Korean POWs. Eisenhower bought Rhee’s acceptance of a cease-fire with pledges of financial aid and a mutual security pact.

An armistice ended fighting in Korea on July 27, 1953. Since then, Koreans have seen the war as the second-greatest tragedy in their recent history after Japanese colonial rule. Not only did it cause devastation and three million deaths, it also confirmed the division of a homogeneous society after thirteen centuries of unity, while permanently separating millions of families. Meanwhile, US wartime spending jump-started Japan’s economy, which led to its emergence as a global power. Koreans instead had to endure the living tragedy of yearning for reunification, as diplomatic tension and military clashes along the demilitarized zone continued into the twenty-first century.

Korea’s war also dramatically reshaped world affairs. In response, US leaders vastly increased defense spending, strengthened the North Atlantic Treaty Organization militarily, and pressed for rearming West Germany. In Asia, the conflict saved Chiang’s regime on Taiwan, while making South Korea a long-term client of the US. US relations with China were poisoned for twenty years, especially after Washington persuaded the United Nations to condemn the PRC for aggression in Korea. Ironically, the war helped Mao’s regime consolidate its control in China, while elevating its regional prestige. In response, US leaders, acting on what they saw as Korea’s primary lesson, relied on military means to meet the challenge, with disastrous results in Việt Nam.

Soldiers Walking Down Road(Original Caption) As soldiers at right are briefed, other ROK Troopers move up the road to forward positions for counterattack against Chinese Communists who launched one of the fiercest assaults of the Korean War on the central front. ROK Troops regained more than 60 square miles of territory lost in the Red assault, by July 20th, Korean time.

The Korean war began on June 25, 1950, when some 75,000 soldiers from the North Korean People’s Army poured across the 38th parallel, the boundary between the Soviet-backed Democratic People’s Republic of Korea to the north and the pro-Western Republic of Korea to the south. This invasion was the first military action of the Cold War. By July, American troops had entered the war on South Korea’s behalf. As far as American officials were concerned, it was a war against the forces of international communism itself. After some early back-and-forth across the 38th parallel, the fighting stalled and casualties mounted with nothing to show for them. Meanwhile, American officials worked anxiously to fashion some sort of armistice with the North Koreans. The alternative, they feared, would be a wider war with Russia and China–or even, as some warned, World War III. Finally, in July 1953, the Korean War came to an end. In all, some 5 million soldiers and civilians lost their lives in what many in the U.S. refer to as “the Forgotten War” for the lack of attention it received compared to more well-known conflicts like World War I and II and the Vietnam War. The Korean peninsula remains divided today.

North vs. South Korea

“If the best minds in the world had set out to find us the worst possible location in the world to fight this damnable war,” U.S. Secretary of State Dean Acheson (1893-1971) once said, “the unanimous choice would have been Korea.” The peninsula had landed in America’s lap almost by accident. Since the beginning of the 20th century, Korea had been a part of the Japanese empire , and after World War II it fell to the Americans and the Soviets to decide what should be done with their enemy’s imperial possessions. In August 1945, two young aides at the State Department divided the Korean peninsula in half along the 38th parallel . The Russians occupied the area north of the line and the United States occupied the area to its south.

Did you know? Unlike World War II and Vietnam, the Korean War did not get much media attention in the United States. The most famous representation of the war in popular culture is the television series “M*A*S*H,” which was set in a field hospital in South Korea. The series ran from 1972 until 1983, and its final episode was the most-watched in television history.

By the end of the decade, two new states had formed on the peninsula. In the south, the anti-communist dictator Syngman Rhee (1875-1965) enjoyed the reluctant support of the American government; in the north, the communist dictator Kim Il Sung (1912-1994) enjoyed the slightly more enthusiastic support of the Soviets. Neither dictator was content to remain on his side of the 38th parallel, however, and border skirmishes were common. Nearly 10,000 North and South Korean soldiers were killed in battle before the war even began.

The Korean War and the Cold War

Even so, the North Korean invasion came as an alarming surprise to American officials. As far as they were concerned, this was not simply a border dispute between two unstable dictatorships on the other side of the globe. Instead, many feared it was the first step in a communist campaign to take over the world. For this reason, nonintervention was not considered an option by many top decision makers. (In fact, in April 1950, a National Security Council report known as NSC-68 had recommended that the United States use military force to “contain” communist expansionism anywhere it seemed to be occurring, “regardless of the intrinsic strategic or economic value of the lands in question.”)

“If we let Korea down,” President Harry Truman (1884-1972) said, “the Soviet[s] will keep right on going and swallow up one [place] after another.” The fight on the Korean peninsula was a symbol of the global struggle between east and west, good and evil, in the Cold War. As the North Korean army pushed into Seoul, the South Korean capital, the United States readied its troops for a war against communism itself.

At first, the war was a defensive one to get the communists out of South Korea, and it went badly for the Allies. The North Korean army was well-disciplined, well-trained and well-equipped; Rhee’s forces in the South Korean army, by contrast, were frightened, confused and seemed inclined to flee the battlefield at any provocation. Also, it was one of the hottest and driest summers on record, and desperately thirsty American soldiers were often forced to drink water from rice paddies that had been fertilized with human waste. As a result, dangerous intestinal diseases and other illnesses were a constant threat.

By the end of the summer, President Truman and General Douglas MacArthur (1880-1964), the commander in charge of the Asian theater, had decided on a new set of war aims. Now, for the Allies, the Korean War was an offensive one: It was a war to “liberate” the North from the communists.

Initially, this new strategy was a success. The Inch’on Landing , an amphibious assault at Inch’on, pushed the North Koreans out of Seoul and back to their side of the 38th parallel. But as American troops crossed the boundary and headed north toward the Yalu River, the border between North Korea and Communist China, the Chinese started to worry about protecting themselves from what they called “armed aggression against Chinese territory.” Chinese leader Mao Zedong (1893-1976) sent troops to North Korea and warned the United States to keep away from the Yalu boundary unless it wanted full-scale war.

'No Substitute for Victory'

This was something that President Truman and his advisers decidedly did not want: They were sure that such a war would lead to Soviet aggression in Europe, the deployment of atomic weapons and millions of senseless deaths. To General MacArthur, however, anything short of this wider war represented “appeasement,” an unacceptable knuckling under to the communists.

As President Truman looked for a way to prevent war with the Chinese, MacArthur did all he could to provoke it. Finally, in March 1951, he sent a letter to Joseph Martin, a House Republican leader who shared MacArthur’s support for declaring all-out war on China–and who could be counted upon to leak the letter to the press. “There is,” MacArthur wrote, “no substitute for victory” against international communism.

For Truman, this letter was the last straw. On April 11, the president fired the general for insubordination.

The Korean War Reaches a Stalemate

In July 1951, President Truman and his new military commanders started peace talks at Panmunjom. Still, the fighting continued along the 38th parallel as negotiations stalled. Both sides were willing to accept a ceasefire that maintained the 38th parallel boundary, but they could not agree on whether prisoners of war should be forcibly “repatriated.” (The Chinese and the North Koreans said yes; the United States said no.) 

Finally, after more than two years of negotiations, the adversaries signed an armistice on July 27, 1953. The agreement allowed the POWs to stay where they liked; drew a new boundary near the 38th parallel that gave South Korea an extra 1,500 square miles of territory; and created a 2-mile-wide “demilitarized zone” that still exists today.

Korean War Casualties 

The Korean War was relatively short but exceptionally bloody. Nearly 5 million people died. More than half of these–about 10 percent of Korea’s prewar population–were civilians. (This rate of civilian casualties was higher than World War II’s and the Vietnam War’s .) Almost 40,000 Americans died in action in Korea, and more than 100,000 were wounded. Today, they are remembered at the Korean War Veterans Memorial near the Lincoln Memorial on the National Mall in Washington, D.C., a series of 19 steel statues of servicemen, and the Korean War memorial in Fullerton, California , the first on the West Coast to include the names of the more than 30,000 Americans who died in the war.

How presidents spark and sustain support for wars remains an enduring and significant problem. Korea was the first limited war the United States experienced in the contemporary period—the first recent war fought for something less than total victory. This book explores how Truman and then Eisenhower tried to sell it to the American public. Based on primary sources, this book explores the government's selling activities from all angles. It looks at the halting and sometimes chaotic efforts of Truman and Acheson, Eisenhower and Dulles. It examines the relationships that they and their subordinates developed with a host of other institutions, from Congress and the press to Hollywood and labor. And it assesses the complex and fraught interactions between the military and war correspondents in the battlefield theater itself. From high politics to bitter media spats, this book guides the reader through the domestic debates of this messy, costly war. It highlights the actions and calculations of colorful figures, including Taft, McCarthy, and MacArthur. It details how the culture and work routines of Congress and the media influenced political tactics and daily news stories. And the book explores how different phases of the war threw up different problems.

Suggested Sequencing

Use this narrative with the Truman Intervenes in Korea Decision Point, the Truman Fires General Douglas MacArthur Decision Point, and the Harry S. Truman, “Truman Doctrine” Address, March 1947 Primary Source to have students analyze the United States’ involvement in the conflict.

On June 25, 1950, North Korea invaded South Korea and rapidly swept through the nation until it controlled all but a small perimeter around Pusan at the southern tip of the Korean Peninsula. President Harry Truman was concerned about containing Soviet expansion because of the Russian explosion of an atomic bomb and the fall of China to communism the year before. He secured an authorization of force from the United Nations rather than Congress because he considered his planned intervention in South Korea to be a “police action.” General Douglas MacArthur was named supreme commander of a U.N. coalition of forces led by the United States as the nation went to war.

The U.N. armies counterattacked the North Koreans and gained back much of the territory belonging to the South. On September 15, 1950, the First Marine Division under General Oliver Prince Smith made an amphibious landing at Inchon behind enemy lines and quickly took control of Seoul, the capital of South Korea, with the X Corps of the U.S. Army. Not satisfied with regaining South Korea, General MacArthur secured support from the U.N. and the U.S. Joint Chiefs of Staff, and permission from President Truman to send American and allied troops past the 38th parallel and into North Korea.

On October 5, Chinese Foreign Minister Chou En-lai warned that if U.N. troops crossed the 38th Parallel into North Korea, China would intervene in the war. MacArthur shrugged off the warning, and U.N. forces took the North Korean capital, Pyongyang, two weeks later. MacArthur then sent his forces farther north in several columns toward the Yalu River, on the border with China.

A map shows the Korean Peninsula with major cities labeled. Lines with arrows pointing north show U.N. advances after the landing at Inchon. One line starts near P'ohang-dong and travels north along the east coast to Hyesanjin and to Chongjin. Another line starts near Uijonbu, just north of Seoul, and travels north and slightly west to Sinuiju. Another line starts near Munsan-ni, north of Seoul, and travels north to the edge of the map. Another line starts east of Pyongyang and travels north past the edge of the map.

The map shows the northern advance of U.N. forces past the 38th Parallel toward the Chinese border.

The plan was for the First Marine Division to push its way to the objective of the Yalu along the northeastern part of the peninsula, through the forbidding Taebaek Mountains and supported by the 1st Marine Air Wing and the 11th Artillery. MacArthur described the area as a “merciless wasteland . . . locked in a silent death grip of snow and ice.”

The Marines and Army troops sailed to Wonsan in North Korea, where they disembarked 100 miles north of the 38th parallel. General Smith opposed the plan to march through the Taebaeks because of the arctic temperatures, narrow roads vulnerable to ambush, and thin supply lines likely to be cut. He was also concerned about Central Intelligence Agency (CIA) and military reports of contact with the Chinese, but MacArthur was unworried and urged the Marines forward.

From October 19 to 25, approximately 300,000 battle-hardened Chinese troops who had fought in the Chinese Civil War crossed the Yalu. The Chinese Ninth Army Group, 120,000 soldiers strong, swarmed into the Taebaeks. They camouflaged their movements by traveling at night and covering themselves with white sheets in the snow. The Chinese planned to use their numbers to overwhelm the Marines, who had superior firepower.

General Song Shilun, center, was the commander of the Chinese Ninth Army Group at Chosin, Korea, in 1950.

Just before midnight on November 2, the Chinese attacked the 3,000 Marines of the 7th Regiment under Colonel Homer Litzenberg at the village of Sudong, on the road to Hagaru-ri. The Chinese forces surged in human waves that were annihilated by Marine machine guns, rifles, and mortars. The Marines killed almost 1,000 Chinese and lost only 61 of their own. The enemy disappeared after the probing attack, having gained valuable information about the Marines’ capabilities as well as about U.S. and South Korean armies elsewhere in the area.

General Smith selected Hagaru-ri village as a forward base on the southeastern tip of the Chosin Reservoir. He ordered the artillery to deploy their batteries and the engineers to build an airstrip and supply depot. Smith sent Marines to cover East Hill, the heights overlooking the village. Marine infantrymen of the 7th Regiment Easy Company marched 14 miles to the northwest, to Hill 1282, which had a commanding view of the village of Yudam-ni. Fox Company was given the critical job of occupying a hill next to Toktong Pass, the only road linking Hagaru-ri to Yudam-ni, so their fellow Marines could be supplied and would not be cut off. They arrived on November 27 and immediately started digging in, despite biting temperatures of ?25°F with strong winds.

The Fox Company Marines deployed in a horseshoe formation around the perimeter of the hill, anchored to a high embankment in the road. The front units laid out foxholes in a standard formation of two foxholes with one behind. Half the Marines went to sleep in heavy sleeping bags while the other half kept watch. They could not light fires because they had to hide their positions.

At 2:00 a.m., a large formation of Chinese in white uniforms attacked. They blew whistles and bugles and clanged cymbals, relying on sheer numbers rather than surprise. Soon, grenade explosions and machine-gun and rifle fire added to the deafening noise. There were so many Chinese that the Americans did not even aim their weapons. Within minutes, their American front-line positions were overrun and dozens were dead or wounded. Still, they fought back tenaciously.

Privates Hector Cafferata and Ken Benson were in a foxhole together when a grenade landed right on top of them. Benson grabbed it and it exploded in his face, temporarily blinding him. Cafferata fired a machine gun or rifle while Benson reloaded ammunition into empty weapons. Cafferata threw grenades as well and swung his shovel like a baseball bat to knock enemy grenades back down the hill. He was about to throw another one when it exploded in his hand and shredded his fingers. Nevertheless, he kept firing the weapons that Benson handed him. Captain William Barber rallied his troops at the top of the hill and moved among his men under fire to bolster their courage throughout the night.

The story was much the same on Hill 1282 at Yudam-ni, where Easy Company was under heavy attack all night and almost lost the hill until they counterattacked and gained a brief respite. They suffered significant casualties. East Hill on Hagaru-ri was beleaguered as well and barely held. U.S. Army units to the east of the reservoir and South Korean forces farther east were also hit hard during the first night. Chinese casualties totaled nearly 10,000 from these battles the first day.

As the sun rose over the rugged landscape, the exhausted Marines on Fox Hill counted 24 dead, 50 wounded, and three missing, cutting their effective strength by one-third. Captain Barber counted more than 450 enemy dead strewn all over the hill, with almost 100 in front of Cafferata and Benson’s foxhole. The extreme cold had clotted the bleeding from most of their wounds, but it also caused numerous cases of frostbite among the Marines. The soldiers helped the wounded and ate cold rations. Their spirits were lifted by support from airstrikes by Marine Corsairs and artillery barrages. In addition, cargo planes began dropping bundles of medical supplies, food, ammunition, radio batteries, and blankets.

The wounded from the battle at Fox Hill in Korea, 1950, were evacuated by plane to be helped elsewhere.

The Chinese, however, launched massive attacks during the next few nights. As the fighting grew desperate, dozens of wounded Marines in field hospitals gritted their teeth, grabbed a weapon, and straggled back to the fighting. One partially paralyzed man with his spine exposed from a gunshot wound tried to get up and fight but was stopped by a corpsman. Because the Marine Corps abided by the slogan, “Every Marine a rifleman,” cooks, mechanics, and drivers picked up weapons and entered the fray on the various hills.

By the morning of November 29, the Chinese had won control of East Hill and threatened Smith’s camp and airfield. As a result, Colonel Lewis “Chesty” Puller, commanding the First Regiment to the south at Koto-Ri, moved ahead toward Hagaru-ri with some British Royal Marines. The Chinese assaulted the allied relief column and knocked out vehicles on the narrow road, causing a deadly traffic jam. They killed more than 300 allies and took a few dozen survivors prisoner. The men in the rear could not get through and returned. About 400 men in the lead made it to the destination and successfully drove the Chinese from East Hill. They repulsed an attack that night and killed 1,500 Chinese soldiers. As a result of their valiant efforts, the airstrip was completed on December 1 and formed a vital link to the outside world, with cargo planes bringing in reinforcements and supplies and carrying out the wounded.

On December 3, the severely depleted companies of Marines at Yudam-ni sneaked their way back to Fox Hill led by Chinese-American Lieutenant Kurt Chew-Een Lee and helped relieve Fox Company. They subsequently became known as the “Ridgerunners.” Marine aircraft and artillery helped open the Toktong Pass as approximately 2,000 wounded Marines walked or were carried back to Hagaru-ri. As dusk settled, the bloody, ragged, unshaven, and unwashed Marines in tattered clothing marched into the base. One lieutenant colonel shouted to the men, “You people will now shape up and look sharp. We’re going in like United States Marines.” Everyone in the base stopped what they were doing and silently watched the proud men marching in perfect unison singing the Marines’ Hymn. The Army soldiers from east of the reservoir had been decimated and struggled back in smaller groups.

When asked about the retreat, General Smith retorted, “Retreat, hell! We’re just attacking in a different direction.” The entire division prepared to fight its way back to the coast, using airpower and artillery to pummel the Chinese, who had dug in around the main road and the bridge at Funchilin Pass, which they had blasted to prevent the American withdrawal. Marine engineers fixed the bridge, and the First Marine Division marched or rode back to the port of Hungnam to their transports for evacuation, especially for the wounded. Army General Ned Almond facilitated the humanitarian evacuation of 100,000 North Koreans to the south.

The Marines suffered 750 dead and 3,000 wounded as they fought against the Chinese and caused more than 42,000 enemy casualties, costing the Chinese Ninth Army Group two divisions and effectively rendering it ineffective as a fighting force. The Chinese and North Koreans later drove the U.N. forces back down to the 38th parallel, where the war remained at a stalemate until peace was made in 1953. After World War II, some U.S. policy makers had wondered whether the Marines were necessary, but the Battle of the Chosin Reservoir changed their minds. Korea was one of the main battlegrounds of the early Cold War.

The Korean War: 1950-1953 Essay

Introduction, works cited.

The Second World War marked the starting of the Korea predicament. According to SparkNotes, the 1950-1953 war started when the South Koreans, who were non communists, were attacked by the communist army of North Korea. This is when the Allies were assigned to take over the Korean cape that was previously engaged by Japan.

It is during the 38 th parallel that the Korean responsibility was divided between the Soviet Union and the United States. According to the Australian War Memorial, the years that followed saw the Soviet Union promote a tough collective administration in the north, while in the south, the government received support from the US. Anxiety rose by the mid 1950 amid the two regions, with each one of them being governed by a different government, up to the position where each one of the aggressive armies was reinforcing along the boundary.

On 25 of June 1950, the army of the North Korea lastly made its way into the southern region, and proceeded towards Seoul, the capital (Turner Publishing Company 15). In a period that was less than seven days, the city fell. This saw the North Korean military precede their way to the south, towards the significant Pusan port, deliberately.

In two days time, South Korea received support from the US which included both sea and air. According to SparkNotes, the Security Council of the United Nations requested for all its members to help in repelling molest by the North Koreans. This received a good response as troops, medical squads, aircraft, and ships, were offered by twenty one countries.

According to Australian War Memorial, Australia offered the Australian Royal Regiment, 77 RAAF Squadron, and the 3 rd Battalion. During this point in time, both of them were located in Japan where they formed a component of the Occupation Force of the British Commonwealth.

SparkNotes records that, United States did not consider Korea as of strategic importance, but at this period, the Cold War political environment was one that would define that policy makers were tough on communism. Technically, the intervention by the US was in form of police action that was managed by a peace keeping force of the United Nations. In reality, the US and the anti communists of NATO were maneuvering the UN to suit their own interests (Poulantzas 332).

The Inchon attack

In September 1950, while the US, the South Korean, and the UN armies stuck beside the sea at Pusan, Spaknotes records that, a bold amphibious attack was coordinated by Douglas C. McArthur on Inchon. This is a port located on Koreas Western coast. MacArthur, who used to be the Southwest Pacific commander during the Second World War, oversaw Japan’s occupation period after war. He also was in charge of the UN army in the early stages of the war in Korea.

With this accomplishment, McArthur evoked the South Korea capital, Seoul, through a pincer progress thereby overwhelming the North Korea army which by then was attacking Pusan (Poulantzas 331). He did not get contented with this fast mission he made on South Korea, but with the help of the US, he traversed the 38 th parallel. He chased the North Korean forces up to the North Korea northern most provinces (Poulantzas 332).

Chinese Intrusion

Scared, an army was clandestinely sent by the China Republic across River Yalu (Poulantzas 331). This is because the China Republic thought that US wanted to use North Korea to fight Manchuria. The Chinese force assaulted the US, the South Korea, and the UN armies. As of Australian War Memorial, when Lt. General Mathew Ridgway was appointed as the ground forces commander, there was progress in the American spirits, making the proposal to sway against the Chinese Communists’.

The Sack of McArthur

With the hope of ending the war fast, President Truman had to dismiss MacArthur as he did not oblige to his orders (Sweeney and Byrne 245). The president wanted him to be more diplomatic, but McArthur, the bright strategist, persisted, issuing provocative lines of his wishes of bringing together Korea.

According to SparkNotes, with the help of the Joint Staff Chiefs, the president was able to remove McArthur from authority. Though the decision was detested by Americans as McArthur was considered an admired war hero, the support of the Joint Staff Chiefs is the one that saved the president from prosecution after the dismissal.

Ridgway as the commander

As per Australian War Memorial, Ridgway held the position of the commander, and avoided the communists with strong defenses and entrenchments, immediate the 38 th parallel north. This is by sending occasional insults against the iron triangle, which was the enactment area for assaults meant for South Korea.

SparkNotes notes that, in the years 1951 and 1952, peace dialogues pulled at Kaesong, then made their way at Panmunjom. Through strategic bombing, the US attempted to frighten the communists into making dialogues of a peace accord, but they refused to move, mainly on the Prisoner of War matter repatriation ((Turner Publishing Company 13).

Both sides wanted to emerge strong making the talks to continue, sometimes stopping for months. This is because the Communists alleged that they were insulted by Mathew Ridgeway, and were demanding for an apology.

According to Australian War Memorial, the negotiations were resumed on October, but the location was changed to Panmunjom. Merely after a war hero, Eisenhower, who did not fear republican disapproval became president, the US formed ample compromises to the communists.

A peace agreement was marked on 27 July1953 at Panmunjom, after seventeen negotiation days, bringing to an end the war in Korea, which lasted for two years (Turner Publishing Company 12).This brought back Korea to a split position, essentially to similar as it was, prior to the war. Both the war and its effect did not contribute to the reduction of the anxiety that was there in the Cold War period.

The war created a crisis in Korea as it destroyed most of the country’s industrial plants. Regardless of the hydroelectric and mineral wealth found in North Korea, the region ended up in poverty, and could not afford to catch up with the financial rate of South Korea.

According to SparkNotes, this made South Korea to be four times the gross domestic product of North Korea. However, North Korea stayed quite sovereign of PRC and USSR authority. Actually, Chinese and Soviet wrangling over the one supposed to settle the bill for the war in Korea was one aspect in the Sino-Soviet Split, obvious soon after the cold war.

The Korean War was a depressing occurrence for the US. This is because it was the first war in which the US involved itself in and lost (Sweeney and Byrne 245). The war which claimed a total of 4 million lives including 50,000 of the US soldiers showed the US that, though it was able to come out of the Second World War as a powerful country, it was unable to firmly and imminently achieve its will and desires. Through this ending, America was able to improve and harden the Cold War policy for its future (Sweeney and Byrne 245).

U.S. Secretly Shipped New Long-Range Missiles to Ukraine

Ukrainian forces for the first time used a longer-range version of weapons known as ATACMS, striking an airfield in Crimea and Russian troops in southeastern Ukraine.

Reporting from Washington

The United States last week secretly shipped a new long-range missile system to Ukraine, and Ukrainian forces immediately used the weapons to attack a Russian military airfield in Crimea last Wednesday and Russian troops in the country’s southeast overnight on Tuesday, according to a senior U.S. official.

The United States previously supplied Ukraine with a version of the Army Tactical Missile Systems — known as ATACMS — armed with wide-spreading cluster munitions that can travel 100 miles.

But Ukraine has long coveted the system’s longer-range version, with a range of about 190 miles. That can reach deeper into occupied Ukraine, including Crimea, a hub of Russian air and ground forces, and supply nodes for Moscow’s forces in the country’s southeast.

Overnight Tuesday, Ukraine used the longer-range missiles to strike Russian troops in the port city of Berdiansk on the Sea of Azov, the senior U.S. official said, speaking on the condition of anonymity to discuss operational matters.

Last Wednesday, social media accounts in Ukraine reported large fires and explosions at a military airfield in Dzhankoi, Crimea, which the senior administration official said was also a long-range ATACMS target. In an address that evening, President Volodymyr Zelensky thanked Gen. Oleksandr Syrsky, the top Ukrainian commander, but did not elaborate on the attack.

In a major policy shift, President Biden secretly approved the decision to send more than 100 of the longer-range missiles in mid-February, the senior U.S. official said, as well as more of the cluster munition variant. They were part of a $300 million shipment of weapons to Ukraine in March, the first new aid package for the country since funding ran out in late December.

Administration officials kept the shipment secret to avoid tipping off the Russians. When the United States has provided long-range weapons to Ukraine in the past, the Ukrainians have initially inflicted severe damage on Russian forces. But the Russians then pull back their forces and arms depots out of the weapons’ range until Ukraine can employ a new donated system with longer reach. The longer-range ATACMS were among the last major weapons systems that Kyiv wanted and the United States was reluctant to give.

Mr. Biden and his top aides dropped their reluctance to donate the longer-range missiles for several reasons, the official said. The Army decided to keep more of the missiles rather than selling them to other countries, easing Pentagon concerns about shortages. Russia’s increasing use of ballistic missiles and more attacks against critical infrastructure also bolstered Ukraine’s plea for weapons that could help counter those threats.

Additional longer-range missiles were also included in the $60.8 billion of aid for Ukraine that was part of legislation President Biden signed on Wednesday. In praising the infusion of military assistance, including the new missiles, lawmakers and Mr. Zelensky have made no mention of the fact that Ukraine already received and employed a small number of the weapons, presumably to keep their use secret from Russia.

The initial strike using the new missiles made a fiery impact. Videos posted online by residents last Wednesday showed fires erupting after the attack. The videos have not been independently verified. Four hours after the strike, Crimean Wind, a group monitoring local social media posts that also cites residents, wrote that ammunition was still blowing up. They said windows were blown out in houses near the airfield. Its account also could not be independently verified.

Later, the Ukrainian General Staff released a video of the missile strike detailing what Ukrainian security officials said had been hit — four S-400 surface-to-air missile systems , three radar stations, an air defense command post and a Fundament-M air defense command and control system.

The $300 million arms package announced last month was cobbled together from savings on contracts that came in under bid and included air defense interceptors, artillery rounds and armor systems, senior defense officials said.

Biden administration officials acknowledged that the arms package in March was a stopgap measure at best, providing Ukraine with only a few weeks’ worth of arms and ammunition. Ukraine is in need of air defense systems, as Russia has continued its bombardment of towns, particularly in the east.

Key members of Congress were notified at the time that the secret shipment of ATACMS was included in that package, but Biden administration officials made no public mention that either type of ATACMS was bound for Ukraine.

But as the strikes by the longer-range weapons became public on Wednesday, proponents of sending advanced weaponry to Ukraine praised their performance.

“These strikes proved — once again — that Ukraine can notch battlefield victories when given the right tools,” Senator Roger Wicker of Mississippi, the senior Republican on the Armed Services Committee, said in a statement. “Ukraine can put a target on every Russian asset in Crimea, including critical ammunition and fuel depots. Imagine if they had these missiles two years ago.”

The strike last week followed a number of successful Ukrainian attacks on military targets inside Russia. The day before the strike, for example, the Ukrainian security service claimed to have destroyed a long-range radar located 434 miles beyond Ukraine’s border. But those used kamikaze-type drones produced in Ukraine.

American military officials have warned that their arsenal of ATACMS is relatively small, and the missiles have been committed for other Pentagon war plans, in places including the Korean Peninsula. Only about 4,000 ATACMS have been manufactured since the missile was developed in the 1980s, according to Lockheed Martin, the system’s manufacturer.

Still, many advocates of arming Ukraine have dismissed the Biden administration’s fear of escalating the conflict with Russia and have urged the White House to give Kyiv the weapons Ukrainian officials say they need to win.

Shortly after Ukraine launched its counteroffensive last summer, House Republicans called on the Biden administration to “immediately” send ATACMS to Ukraine, noting that other allies like Britain and France had already donated long-range missiles.

In the past few days, Russian troops have entered several villages in eastern Ukraine, as Ukrainian troops continue to struggle to hold their lines.

Russia has advanced quickly into the outskirts of Chasiv Yar , a crucial town for Ukraine’s defense of the Donbas region. Russian forces also continued capturing villages northwest of Avdiivka, which fell to Russia in February .
