On 24 November 1950, the Eighth Army occupied a line about 110 kilometres (68 mi) long stretching west to east from the Yellow Sea across the broad coastal plain of the Ch'ongch'on River to the ridges of the Taebaek Mountains. The Eighth Army charged with carrying out the Home for Christmas offensive consisted of four U.S. infantry divisions, eight Republic of Korea Army (ROK) divisions, Turkish and British brigades and
306-537: A UN counter-offensive two months later. After an abortive Chinese spring offensive , UN forces retook territory roughly up to the 38th parallel. Armistice negotiations began in July 1951, but dragged on as the fighting became a war of attrition and the north suffered heavy damage from U.S. bombing . Combat ended on 27 July 1953 with the signing of the Korean Armistice Agreement , which allowed
408-677: A directive to MacArthur on 29 December 1950, the Joint Chiefs of Staff in Washington, instructed MacArthur to "resist aggression" but added that "Korea is not the place to fight a major war." MacArthur was told "to defend...inflicting such damage to hostile forces in Korea as is possible, subject to the primary consideration of the safety of your troops." The Chinese were pleased with the outcome of their Second Phase Offensive, having regained nearly all of North Korea from UN forces. However,
510-509: A general attack across the 38th parallel, rather than a limited operation in Ongjin. Kim was concerned that South Korean agents had learned about the plans and that South Korean forces were strengthening their defenses. Stalin agreed to this change. While these preparations were underway in the North, there were clashes along the 38th parallel, especially at Kaesong and Ongjin, many initiated by

The U.S. divisions occupied the western section of the line, a mostly flat area, while the ROK occupied the hilly and mountainous eastern section of the line. Although less numerous than the PVA who may have numbered as many as 240,000 soldiers, the 130,000 front-line soldiers of the Eighth Army "with modern communications, ample artillery support, tanks and backed by adequate logistic support" were "not significantly inferior in terms of combat power to
816-476: A standstill, the infantry loses the will to fight." Peng would later say, however, that U.S. soldiers "were good at fighting." The Chinese commanders believed that the UN's dependence upon technology could be detrimental to them. The UN forces traveled by roads, they needed a constant supply of artillery supplies; and the infantry operated only during daylight hours and depended upon air cover. Peng's strategy for

The Second Phase Offensive forced all UN forces to go on the defensive and retreat. China had recaptured nearly all of North Korea by the end of the offensive. In late 1950, the United Nations military forces, led by

Soviet generals with extensive combat experience from World War II were sent to North Korea as the Soviet Advisory Group. They completed plans for attack by May and called for a skirmish to be initiated in the Ongjin Peninsula on the west coast of Korea. The North Koreans would then launch an attack to capture Seoul and encircle and destroy

Losses in the Ch'ongch'on battle were about 10,000 from combat and 20,000 from other causes. PVA losses at the Chosin battle were about 20,000 from combat and 30,000 from non-combat. The Chinese claimed to have inflicted 36,000 casualties, including 24,000 Americans, on UN forces. This claim

U.S. intelligence and air reconnaissance failed to detect the large numbers of Chinese soldiers present in North Korea. Thus, the UN units, the Eighth United States Army on the west and the X Corps on the east, kicked off the "Home-by-Christmas" offensive on 24 November with "unwarranted confidence...believing that they comfortably outnumbered enemy forces." The Chinese attacks came as

Records, however, of the Ch'ongch'on battle are incomplete, especially for the ROK forces in the battle. On 28 November 1950, shortly after the onset of the Chinese Second Phase Offensive, MacArthur cabled

While there was hesitance by some in the US government to get involved, considerations about Japan fed into the decision to engage on behalf of South Korea. After the fall of China to the communists, US experts saw Japan as the region's counterweight to the Soviet Union and China. While there
1632-888: The Korean War was an offensive by the Chinese People's Volunteer Army (PVA) against United Nations Command (U.S./UN) forces, most of which were soldiers of South Korea and the United States . The two major engagements of the campaign were the Battle of the Ch'ongch'on River in the western part of North Korea and the Battle of Chosin Reservoir in the eastern part of North Korea. Casualties were heavy on both sides. The battles were fought in temperatures as low as −30 °C (−22 °F) and casualties from frostbite may have exceeded those from battle wounds. On 23 December 1950 Lieutenant General Walton Walker died in

On 24 November a final UN offensive, informally called the "Home-by-Christmas Offensive", to complete the conquest of North Korea began. Most of North Korea was then occupied by UN forces, and the Korean War seemed to be almost over. The UN soldiers and their leaders were optimistic that the Korean War could be concluded by Christmas , 25 December. Despite some indications that substantial numbers of Chinese soldiers were in North Korea, MacArthur played down both

By spring 1950, he believed that the strategic situation had changed: PLA forces under Mao Zedong had secured final victory, US forces had withdrawn from Korea, and the Soviets had detonated their first nuclear bomb , breaking the US monopoly. As the US had not directly intervened to stop the communists in China, Stalin calculated they would be even less willing to fight in Korea, which had less strategic significance. The Soviets had cracked

In five days, the ROK, which had 95,000 troops on 25 June, was down to less than 22,000 troops. In early July, when US forces arrived, what was left of the ROK was placed under US operational command of the United Nations Command . The Truman administration was unprepared for the invasion. Korea

China promised to support the North Koreans in the event of a war against South Korea. By 1948, a North Korea-backed insurgency had broken out in the southern half of the peninsula. This was exacerbated by the undeclared border war between the Koreas, which saw division-level engagements and thousands of deaths on both sides. The ROK
2754-481: The PVA forces could destroy two or three UN divisions, the character of the war would change to the benefit of China and North Korea. The Chinese strategy was dictated in part by their lack of air power, armor, and heavy artillery. After the First Phase Offensive ended on 6 November, Peng ordered the PVA to retreat, feigning weakness and intimidation. However, both the eastern and western branches of

Large U.S. garrisons and air forces were in Japan, but only 200–300 U.S. troops were in Korea. At dawn on 25 June 1950, the KPA crossed the 38th parallel behind artillery fire. It justified its assault with

On 7 June 1950, Kim called for a Korea-wide election on 5–8 August 1950 and a consultative conference in Haeju on 15–17 June. On 11 June, the North sent three diplomats to the South as a peace overture, which Rhee rejected outright. On 21 June, Kim revised his war plan to involve

This operation crippled the insurgency. Soon after, North Korea made final attempts to keep the uprising active, sending battalion-sized units of infiltrators under the commands of Kim Sang-ho and Kim Moo-hyon. The first battalion

3264-436: The Second Phase Offensive was to lure the UN forces into advancing northward into a trap with Chinese forces on all sides of them. That strategy would shorten the supply lines of the logistics-challenged Chinese forces and disperse the UN advancing forces. The Chinese would be familiar with the territory and the UN transportation and supply lifelines would be longer and more vulnerable to attack by guerrillas. Peng reasoned that if
3366-487: The South Korean interior intensified; persistent operations, paired with worsening weather, denied the guerrillas sanctuary and wore away their fighting strength. North Korea responded by sending more troops to link up with insurgents and build more partisan cadres; North Korean infiltrators had reached 3,000 soldiers in 12 units by the start of 1950, but all were destroyed or scattered by the ROKA.

On the eve of the war, KMAG commander General William Lynn Roberts voiced utmost confidence in the ROK and boasted that any North Korean invasion would merely provide "target practice". For his part, Syngman Rhee repeatedly expressed his desire to conquer the North, including when US diplomat John Foster Dulles visited Korea on 18 June. Though some South Korean and US intelligence officers predicted an attack, similar predictions had been made before and nothing had happened. The Central Intelligence Agency noted
3774-739: The Soviet Union would not move against US forces in Korea. The Truman administration believed it could intervene in Korea without undermining its commitments elsewhere. On 25 June 1950, the United Nations Security Council unanimously condemned the North Korean invasion of South Korea with Resolution 82 . The Soviet Union, a veto-wielding power , had boycotted Council meetings since January 1950, protesting Taiwan 's occupation of China's permanent seat .

Citing the inability of the Joint Commission to make progress, the US government decided to hold an election under UN auspices to create an independent Korea. The Soviet authorities and Korean communists refused to cooperate on the grounds it would not be fair, and many South Korean politicians boycotted it. The 1948 South Korean general election was held in May. The resultant South Korean government promulgated

On 1 October 1950, UN Commander General Douglas MacArthur called on North Korea to surrender. There was no response. On 3 October MacArthur announced that UN forces had crossed the border into North Korea . The UN forces proceeded northward toward

Peng Dehuai , the Chinese commander, ended the First Phase Offensive because his soldiers were tired and lacked food and munitions. He also said the Chinese soldiers were fearful of UN air raids and that the cold winter weather would make it "increasingly difficult to preserve
4896-420: The area to that end. The Truman administration still refrained from committing troops on the ground, because advisers believed the North Koreans could be stopped by air and naval power alone. The Truman administration was uncertain whether the attack was a ploy by the Soviet Union, or just a test of US resolve. The decision to commit ground troops became viable when a communiqué was received on 27 June indicating

Joseph Stalin , however, maintained his wartime policy of cooperation, and on 16 August, the Red Army halted at the 38th parallel for three weeks to await the arrival of US forces. On 7 September 1945, General Douglas MacArthur issued Proclamation No. 1 to the people of Korea, announcing US military control over Korea south of

One of their armies of three divisions walked 286 miles (460 km) in 16 to 19 days, an average of up to 18 miles (29 km) daily through mountainous terrain and on poor roads and trails. Marching was at night to avoid aerial surveillance. During the day, the soldiers remained stationary and camouflaged themselves. Scouting parties were sent out ahead during

Mao said that China would infiltrate 12 infantry divisions into North Korea and that another 24 infantry divisions were present in northern China ( Manchuria ) for deployment if necessary. A Chinese infantry division when fully staffed numbered about 10,000 men. Mao also appealed for Soviet military assistance for artillery and air power. Mao said that to defeat
