Early in the morning of June 25, 1950, the armed forces of communist North Korea smashed across the 38th parallel of latitude in an invasion of the Republic of Korea ( South Korea) that achieved complete surprise. Although attacks came all along the border, the major North Korean thrust was in the west of the Korean peninsula, toward Seoul, the capital of South Korea.

South Korea's army, smaller and not as well trained and equipped as that of North Korea, was unable to stem the onslaught. By June 28, Seoul had fallen, and across the peninsula, everywhere south of the Han River, the shattered remnants of South Korea's army were in full retreat. ( See also Korean War Chronology.)

Within hours after the invasion of South Korea began, the United Nations Security Council called for an immediate cease-fire and the withdrawal of North Korean forces from South Korea. North Korea ignored the resolution. Two days later the Security Council urged United Nations members to assist South Korea in repelling its invaders. Both resolutions passed because the Soviet Union was boycotting Security Council meetings. Had the Soviet delegate been present, he surely would have vetoed the measures.

In response, 16 nations sent troops to the aid of South Korea. The United States sent an army; Great Britain, a division; and other nations, lesser units. The heaviest burden of the war, however, was borne by South Korea itself. Its army reached a peak strength of some 400,000 men, maintained that strength only by a steady flow of hastily trained replacements, and sustained an estimated 850,000 combat casualties. The United States Army in Korea ultimately numbered some 300,000 men, supported by about 50,000 Marine, Air Force, and Navy combatants.

The United States reacted even more quickly than did the United Nations. Upon hearing of the North Korean attack, President Harry S. Truman directed General of the Army Douglas MacArthur, commander of the U.S. occupation forces in Japan, to insure the safe evacuation of U.S. civilians and to supply weapons and ammunition to South Korea.

On June 26, United States air and naval forces were directed to support South Korean ground units. The commitment of U.S. ground forces was authorized after General MacArthur inspected the battlefront. The ground forces available to General MacArthur in Japan were four understrength Army divisions composed largely of inexperienced, undertrained men and lacking in heavy weapons.

Early in July the United Nations asked the United States to appoint a commander for all United Nations forces in Korea. President Truman named General MacArthur. Soon thereafter, South Korea placed its forces under the United Nations command.

After the fall of Seoul, North Korea's forces paused briefly to regroup, then resumed their southward drive. South Korea's army resisted bravely but was pushed back steadily. Three United States divisions sent to its aid were committed in small units. They too were driven into retreat.

By late July the remnants of South Korea's army and the United States units had been pressed into a small, roughly rectangular area surrounding the port of Pusan at the southeastern tip of Korea. Here, defending a perimeter roughly 150 miles (240 kilometers) long, the United Nations forces finally were able to hold as reinforcements poured in.

The roots of the Korean War are deeply embedded in history. While few regions are less suited to warfare than is the mountainous, river-slashed Korean peninsula, few have known more conflict. For centuries, Korea's three powerful neighbors- China, Japan, and the Soviet Union-vied for its control. By 1910 Japan had established a supremacy that it was to maintain until its defeat in World War II.

Seven days before the Japanese surrender that ended World War II, the Soviet Union declared war on Japan. Soviet troops entered Korea. By agreement, the Soviet Union accepted the surrender of all Japanese forces in Korea north of the 38th parallel of latitude, while the United States accepted the surrender of Japanese units south of the 38th parallel.

The Soviet Union quickly sealed off the 38th-parallel border. It soon set up an interim civil government for the 9 million Koreans of the north, which contained most of Korea's industry. The government was run by Soviet-trained communist officials.

The United States maintained a military government in the south. The 21 million Koreans of the largely agricultural region were not satisfied with it.

A United States-Soviet commission that was established to make plans for the reunification of Korea under a free government made no progress. In 1947 the United States took the problem before the United Nations, which voted that free elections-under its supervision-should be held throughout Korea in 1948 to choose a single government. The Soviet Union refused to permit the United Nations election commission to enter the north. Elections were thus held only in the south, where a National Assembly and a president- Syngman Rhee -were chosen. The new democracy was named the Republic of Korea (South Korea).

In the north, the Soviet Union proclaimed a communist dictatorship called the Democratic People's Republic of Korea (North Korea). Pyongyang was named its capital. Late in 1948 Soviet forces began to withdraw from North Korea, leaving behind an entrenched communist regime and a well-trained, well-equipped North Korean army. United States occupation forces left South Korea in 1949. They left behind a government still "feeling its way" and an army ill-trained compared with that of the north. This army also lacked air power, tanks, and artillery.

South Korea, however, successfully resisted North Korean attempts at subversion, communist-supported guerrilla activities, and border raids by North Korean forces. Frustrated, North Korea early in 1950 decided upon war to achieve its goal of Korean unification under communist rule.

In June 1950 North Korea's army totaled 135,000 men. North Korea's infantry was also supported by approximately 150 Soviet-made medium tanks, ample artillery, and a small air force. South Korea's ground forces included a 45,000-member national police force and an army of 98,000. South Korea was armed largely with light infantry weapons supplied by the United States. It had no tanks or combat aircraft, and its artillery was inferior to that of North Korea. Its officers and enlisted men had generally less training and experience than did those of North Korea.

While North Korea continued to hurl furious but ineffective attacks at the Pusan perimeter, General MacArthur readied the counterstroke that was to reverse the course of the war-an amphibious assault in his enemy's rear at the port city of Inchon, southwest of Seoul. On September 15 a Marine division swarmed ashore after preparatory bombardment by aircraft and naval guns. An Army division followed. Simultaneously, the Eighth Army-by now a well-equipped and cohesive force-broke out of the Pusan perimeter. Although bloody fighting ensued, Seoul was recaptured within a few days. Thereafter the North Korean army-its supply line severed and its principal withdrawal route blocked by the capture of Seoul-rapidly collapsed. By October 1 its remnants, utterly destroyed as a fighting force, had retreated above the 38th parallel.

North Korea had also met disaster in the air. Late in June, U.S. jet fighters had streaked westward from Japan after a North Korean fighter fired on an American transport. Within two weeks the North Korean air force had ceased to exist, and the United Nations had established an air superiority that it generally was to maintain throughout the war. Even when, later in the war, the communist forces were supplied with Soviet-built jet fighters equal or superior to the U.S. aircraft flown by the United Nations, their Chinese-and sometimes Soviet-pilots proved no match for those of the United Nations. In the course of the war, 14 communist aircraft were shot down for every United Nations plane lost in aerial combat. At sea, under the guns of United States and British warships, North Korea's minuscule navy-a few patrol boats-suffered a fate similar to that of its air force.

In the United Nations, communist delegates indicated that North Korea would now be willing to accept restoration of the 38th parallel as the border between the two Koreas. The United States and South Korea, however, decided to forcibly reunite North and South Korea under the government of South Korea. They disbelieved the threat of communist China that it would intervene if United Nations forces entered North Korea.

United Nations forces began in early October 1950 to press northward. They met only light resistance and by late November had captured virtually all of North Korea. At two points, units reached the Yalu River, the border between North Korea and China.

Shortly after the United Nations advance into North Korea began, however, communist China had secretly begun to infiltrate troops into North Korea. United Nations air patrols detected no sign of them.

United Nations forces had advanced northward in two columns, the Eighth Army in the west and the X Corps in the east, separated by up to 50 miles (80 kilometers) by the central mountain chain of North Korea. Units of both columns were also dispersed and open to attack.

Contacts with communist Chinese units-some in strength-began in late October and continued into early November. Chinese aircraft-Soviet-built MiG-15 jet fighters-first appeared early in November. However, the United Nations command underestimated the strength of the Chinese forces and misread China's intentions. The command planned a final offensive that would bring all of North Korea under United Nations control, confident that United Nations air power could prevent the Chinese from crossing the Yalu River in sufficient strength to stop the offensive. By this time, however, Chinese communist troops in North Korea numbered 300,000.

Late in November, across the snow that heralded a harsh North Korean winter, the Chinese struck. Attacking largely at night, the Chinese-though they suffered tremendous casualties-rapidly dislodged the Eighth Army and X Corps.

In the east, X Corps units were withdrawn by sea from the ports of Hungnam and Wonsan. Surrounded far inland, the lst Marine Division reached Hungnam in one of the great fighting retreats of history. In the west, by land and sea, the Eighth Army also fell back. By the end of December the United Nations forces had been pushed back to a line just south of the 38th parallel. In the face of a renewed Chinese offensive, they withdrew from Seoul and the Han River line early in January 1951.

In the more open terrain of South Korea, the United Nations forces were able to form a fairly continuous line of resistance. They continued to withdraw slowly, exacting a terrible toll of the advancing Chinese, until in mid-January the front stabilized along an undulating line running from the 37th parallel in the west to a point midway between the 37th and 38th parallels in the east.

The entry of China into the war had a heavy impact upon the United States. Draft calls were increased, and more reservists were called to active duty. President Truman declared a state of national emergency, and economic controls were imposed.

Fearing that the wider war with China that would be necessary to reunify Korea would cost too many American lives and raise the risk of nuclear war with the Soviet Union, the United States abandoned the idea of forcibly reuniting the two Koreas. Instead, it decided to accept a rough restoration of the situation that had existed before the war. Although the United Nations declared communist China an aggressor, it agreed with the new U.S. policy. United Nations forces would repel China from South Korea but would not seek to retake the north.

By late January 1951 the Eighth Army-reformed and strengthened and incorporating the X Corps-was ready to advance against the now-weakened Chinese and North Korean armies. Thrusts of infantry and armor were supported by the vastly superior United Nations artillery and air power. Where the communist forces chose to stand, they were slaughtered. In one action alone, 6,000 Chinese men were killed, 25,000 wounded. Seoul was reoccupied by the United Nations in mid-March. By March 31 the battle line stood roughly along the 38th parallel.

Enraged at China's intervention, General MacArthur had dissented vigorously from the new United Nations policy. He wished to press an expanded war against communist China, including forbidden attacks upon "sanctuaries" above the Yalu River. He made his views public. Believing the general's actions to be both insubordinate and dangerous, President Truman relieved him of his commands in April. General MacArthur was replaced by Lieut. Gen. Matthew B. Ridgway, who had commanded the Eighth Army in the field since the death of Lieut. Gen. Walton H. Walker in a jeep accident in December 1950. Command of the Eighth Army was passed to Lieut. Gen. James Alward Van Fleet.

Above the 38th parallel, the Chinese and North Korean forces once again regrouped. In April and in May, their commanders hurled them against the United Nations lines. In response, General Van Fleet's forces slowly withdrew, scourging their attackers with superior firepower. When their adversaries were exhausted by massive casualties and supply shortages, the United Nations forces counterattacked. By mid-June, save for a small sector north of Seoul in the west, the United Nations line stood well above the 38th parallel.

Late in June, the Soviet Union indicated that the communists might be prepared to seek a truce. On June 30, General Ridgway offered to open truce negotiations. North Korea and China accepted.

Truce talks opened on July 10 at Kaesong, some 35 miles (56 kilometers) northwest of Seoul. It quickly became apparent that the opposing sides had different goals at the truce table. The United Nations sought only an honorable end to the war. North Korea and China, however, undertook to win in conference what they had been unable to attain on the battlefield. The communists made every effort to embarrass and humiliate United Nations delegates, to force concessions through intransigence and delay, and to use the conference as a propaganda forum.

Although it was agreed that hostilities were to continue during the truce talks, no more major offensives were conducted during the war. A lull in the fighting developed as the talks opened; both sides used it to strengthen their forces. The communist buildup was hampered-though not halted-by United Nations naval and air forces.

Late in August, the communists broke off the truce talks. General Van Fleet promptly launched a limited offensive to straighten and improve the United Nations lines. By mid-October, defeated again, the communists offered to reopen the truce talks.

The meeting site was moved to Panmunjom, some 5 miles (8 kilometers) east of Kaesong. Here the armistice talks were to drag on, with intermittent recesses, for another year and a half, stalling repeatedly over such issues as the establishment of a truce line and the repatriation of prisoners. Along the front, meanwhile, the fighting settled into a modernized version of the grinding trench warfare of World War I.

In order to maintain the military pressure that seemed essential to serious negotiations, the United Nations insisted that the truce line be the line of contact between the opposing armies at the time the truce was signed. Finally, a line was agreed upon. Finally, too, the communists agreed that prisoners who did not wish to return to their homelands did not have to. At first, they had insisted that the United Nations return, by force if necessary, all the communist prisoners it held. Nearly half of all the prisoners held by the United Nations-and three quarters of the Chinese-did not wish to return to communist rule. The truce agreement was finally signed July 27, 1953, and that day, at 10:00 pm, Korean time, the guns fell silent along the blood-soaked main line of resistance.

The conclusion of the cease-fire had probably been hastened by events outside of Korea. First, General of the Army Dwight D. Eisenhower, who succeeded Truman as president of the United States in January 1953, had hinted broadly that military pressure might be sharply increased if the fighting did not end soon. Second, the death in March 1953 of Soviet dictator Joseph Stalin caused a general turning inward of the communist world.

After the cease-fire, the opposing forces each withdrew 1 ¹/ ₄ miles (2 kilometers) from the truce line. The armistice agreement had provided for a conference to seek a permanent peace, but-in the face of communist intransigence-it was delayed for many years. U.S. troops remained in South Korea, and heavily armed North Korean and South Korean forces still faced each other across a narrow demilitarized zone. Truce violations remain common.

In the 1980s, there was no lessening of tensions, but also no serious move toward armed confrontation. North Korean President Kim Il Sung offered a unification plan that was rejected by South Korea. Kim also berated the United States for a plan to install medium range nuclear missiles in the South. But he renewed his call for a peace treaty with the Americans, probably desiring to decrease his dependence on the Soviet Union and China.

United States government documents declassified in the 1990s revealed that the Pentagon knew of at least 900 American soldiers who were held captive at the end of the war and never released. Eisenhower worked covertly for the prisoners's release but was unsuccessful.

The Korean War is a war that was fought between two countries, North Korea and South Korea.

It all started in 1950 when 75,000 soldiers from the North Korean People's Army poured across the 38th parallel which divides Korea into North Korea (communist) and South Korea (democratic).

American troops soon entered as well to help south Korea.

This war lasted for 3 years with back and forth battles.

The Korean peninsula is where the US and the USSR fought a war that lasted from 1951 to 1953. Two people in the State Department were given the choice about what they would do with Korea after Japan lost it in World War II.

They agreed and divided it into two parts: North and South Korea. The Russians got the north and the Americans got the south.

Two new states formed in the south and north of Korea. Syngman Rhee was anti-communist, and Kim Il Sung was communist. The Americans let Syngman Rhee rule in the south, but they let Kim Il Sung rule in the north.

Both dictators wanted to be on the other side of the 38th parallel. They fought a lot and thousands died. They still did not want to stop fighting because they were trying to get more land.

Causes Of The Korean War

The war began when Japan took over Korea. They were in charge for a long time.

But then World War II ended and the Allied powers had to take over Japan's empire. When they did, the US and the Soviet Union had to work out what to do with Korea. They made a deal about it.

When the allies got together again in 1948, they made two separate countries. One was led by Kim Il-sung and the other by Syngman Rhee. The former allies didn't trust each other, so they made these two separate countries so that no one could hurt anyone else.

North Korea invaded its neighbor in 1950. North Korea attacked the South that year, and it started the war between communist countries. It was the first time a war had happened in the Cold War.

The Korean War In The Middle Of The Cold War

The North Korean invasion was a surprise to the American government. Yet they knew that it was more than just a border dispute between two dictatorships. They thought it was the first step in a communist campaign to take over the world.

Some top officials did not see intervention as an option. They thought that the US military should be used to stop communist expansionism anywhere it seemed to be happening, even if the land was not strategic or valuable.

Harry Truman was the US president. He said that if he let Korea down, the Soviets would keep on going and take over other places.

The Korean War was a symbol of what happened in the Cold War between East and West. The North Korean army went into South Korea's capital, Seoul. The US got ready to fight communism itself because they did not want it taking over other places like Korea.

At first, the war was to get communists out of South Korea. It was hard for Allies. The North Korean army had trained soldiers and well-equipped guns. On the other hand, the forces in the South Korean army were not very well prepared.

At the beginning of the war, armies would move forward and then back. The North Koreans attacked and drove United Nations Command forces to a narrow perimeter around Pusan.

After this, General MacArthur surprised the North Koreans in September 1950 with an amphibious landing at Inchon. The North Koreans had to retreat behind the 38th parallel.

New Strategies

On top of that, the weather that year was very hot and dry. American soldiers had to drink water from rice paddies that were fertilized with human waste. That made them very sick because they were thirsty.

So President Truman and General Douglas MacArthur decided on a new set of war aims. The Korean War was offensive: it was a war to "liberate" the North from the communists.

The United States' new strategy was successful at first. The Inch'on Landing at Inch'on pushed the North Koreans out of Seoul and back to their side of the 38th parallel.

President Truman said that he was considering using atomic bombs in Korea. He made this comment at a press conference. This caused some people to panic.

The British Prime Minister came to Washington because of what Truman had said. But then Truman reassured him that the US would not use atomic weapons in Korea unless a major disaster or war problem was happening there between the North and South Koreans.

China Answers Back

When American troops crossed the boundary and headed north toward the Yalu River, China started to worry about protecting themselves from "armed aggression" against Chinese territory. Mao Zedong, the Chinese leader, wanted to help North Korea.

Mao Zedong warned the United States to keep away from the Yalu boundary unless it wanted full-scale war. He planned to use the Chinese People's Volunteers Army (CPVA) to save North Korea. He sent in 250,000 troops in November 1950.

They began a counterattack and continued with two offensives in 1950 and 1951. These unexpected attacks drove the United Nations forces south of Seoul and the Han River Valley.

Truman vs MacArthur

President Truman and his advisers did not want a war with the USSR. They were sure that such a war would lead to Soviet aggression in Europe, the deployment of atomic bombs, and many deaths. General MacArthur disagreed and wanted to start a wider war because he felt like this was necessary.

President Truman wanted to keep peace with the Chinese. General MacArthur, however, tried to make war happen.

Finally, in 1951 General MacArthur sent a letter to someone in Congress who liked fighting with China and was very opinionated about it. President Truman did not like this so he fired him for insubordination.

Stalemate

US soldiers pass fleeing refugees in the Nakdong River region, in what is now South Korea, during the Korean War.

In July 1951, President Truman and his military commanders started peace talks at Panmunjom. The fighting continued along the 38th parallel as negotiations stalled.

Both sides wanted a ceasefire that kept the 38th parallel boundary. Yet they could not agree if prisoners of war should be turned back. China and North Korea agreed, but the US did not.

Fighting in Korea ended in July 1951 and the two sides started talking about an armistice. The talks took a long time because Stalin, the USSR leader, died in March 1953.

But when new leaders came, they were more likely to agree so they signed the armistice on July 27, 1953.

It made a new boundary that allowed South Korea to have more territory (around 1,500 square miles). It also created a 2-mile-wide "demilitarized zone" that is still there today.

Consequences of the Korean War

The Korean War was bloody. Half of the people who died were civilians. That is 10% of Korea's population before the war started. Estimates of the number of people who died during this time vary. But we think that more than two million civilians died in North Korea.

The border between North Korea and South Korea remained in the same place as it was before North Korea invaded.

The Armistice finished the war in Korea and put armed forces to peace. But no peace treaty was made to re-establish relations between North and South Korea. A demilitarized zone, DMZ, was made. Both sides maintain a military presence there but only one side is allowed to be armed.

The countries have had periods where they are friendly and other periods when they are angry with each other. Some family members live in one country and work in another country, but their families are not together. North Korea has been making threats about nuclear programs which have led the United States to keep troops there.

The "Forgotten War"

The Korean War was called the "forgotten war" because it received less attention than other wars. The legacy of this war is still important today. Not only does it still shape geopolitics, but the US also started permitted US presidents to become involved in wars without Congress's approval.

The Korean War did not get much attention in the US. The most famous representation of the war in popular culture is the television series "M*A*S*H." It was set in a field hospital in South Korea. That show ran from 1972 until 1983, and its final episode was the most-watched TV episode ever.

Many US Korean War Veterans are remembered every day at the Korean War Veterans Memorial near Washington D.C., with statues of servicemen that represent them all.

Many soldiers were not accounted for at the end of the war. About 80,000 South Korean soldiers were caught in North Korea when the war ended. The North denies they took them prisoner- but defectors and South Korean officials say that these soldiers were put to work as forced laborers. Most of these prisoners will never be found because their remains are gone.
