Korean War
On the 25th of June 1950, the Korean People's Army crossed the 38th parallel at dawn, launching a surprise invasion that would ignite a global conflict. This was not merely a civil war between two Korean states but the first major proxy war of the Cold War, drawing in the Soviet Union, China, and the United Nations. The attack caught the South Korean government and its American allies completely off guard, as the Republic of Korea had no tanks, no heavy artillery, and only a 22-plane air force composed of liaison and trainer aircraft. Within days, the North Korean forces, equipped with 274 T-34-85 tanks and 200 artillery pieces supplied by the Soviets, routed the South Korean army. By the 28th of June, Seoul had fallen, and the South Korean government, led by Syngman Rhee, was forced to evacuate. The invasion was justified by North Korea as a necessary action to arrest the bandit traitor Syngman Rhee, but the reality was a brutal military campaign that would result in the deaths of hundreds of thousands of civilians and soldiers. The United Nations Security Council, with the Soviet Union boycotting the meeting, unanimously condemned the attack and called for member states to repel the invasion. The United States, under President Harry S. Truman, quickly committed air and sea forces to the defense of South Korea, setting the stage for a three-year war that would become known as the Forgotten War due to the lack of public attention it received relative to World War II and the Vietnam War.
The Division of Korea
The roots of the Korean War lay in the division of Korea following World War II, when the Soviet Union and the United States agreed to divide the Korean Peninsula at the 38th parallel. The Soviet Union entered northern Korea on the 8th of August 1945, securing most major cities by the 24th of August, while the United States occupied the southern half. The division was arbitrary, with US Colonels Dean Rusk and Charles H. Bonesteel III proposing the 38th parallel as the dividing line, even though it was further north than could be realistically reached by US forces in the event of Soviet disagreement. The Soviet Union halted at the 38th parallel for three weeks to await the arrival of US forces, and on the 7th of September 1945, General Douglas MacArthur issued Proclamation No. 1, announcing US military control over Korea south of the 38th parallel. The division led to the formation of two separate governments in 1948, with North Korea led by Kim Il Sung in Pyongyang and South Korea by Syngman Rhee in Seoul. Both claimed to be the sole legitimate government of all of Korea, setting the stage for a conflict that would last for three years. The division was exacerbated by political disagreements and the failure of the US-Soviet Union Joint Commission to make progress on granting independence after a five-year trusteeship. The Soviet Union and the United States withdrew their forces in 1948 and 1949 respectively, leaving the Korean Peninsula divided and vulnerable to conflict.
When did the Korean War start and what triggered the conflict?
The Korean War started on the 25th of June 1950 when the Korean People's Army crossed the 38th parallel at dawn. This surprise invasion ignited a global conflict that drew in the Soviet Union, China, and the United Nations.
Who were the main leaders of North Korea and South Korea during the Korean War?
North Korea was led by Kim Il Sung in Pyongyang while South Korea was led by Syngman Rhee in Seoul. Both leaders claimed to be the sole legitimate government of all Korea, setting the stage for a three-year war.
What was the significance of the Inchon landing during the Korean War?
The Inchon landing occurred on the 15th of September 1950 and was recommended by General Douglas MacArthur to cut off North Korean troops and supply lines. This amphibious operation involved 40,000 troops of the 1st Marine Division and 7th Infantry Division along with 8,600 ROK soldiers.
When did China enter the Korean War and what was the result of their involvement?
The Chinese People's Volunteer Army crossed the Yalu River on the 19th of October 1950 to enter the war on the side of North Korea. Their entry changed the attitude of the Soviet Union and led to heavy losses for UN forces during battles like the Battle of the Ch'ongch'on River.
When did the Korean War end and what agreement was signed?
Combat ended on the 27th of July 1953 with the signing of the Korean Armistice Agreement. This agreement allowed the exchange of prisoners and created a Demilitarized Zone along the frontline with a Joint Security Area at Panmunjom.
By August 1950, the United Nations forces were hemmed into a corner of southeast Korea, near Pusan, in a line defined by the Nakdong River. The North Korean People's Army had pushed back the South Korean and US forces, forcing the 24th Infantry Division to retreat to Taejeon, which the KPA captured in the Battle of Taejon. The 24th Division suffered 3,602 dead and wounded and 2,962 captured, including its commander, Major General William F. Dean. The impact of the Truman administration's defense budget cutbacks was keenly felt, as US troops fought costly rearguard actions. The United States Air Force interrupted KPA logistics with 40 daily ground support sorties, which destroyed 32 bridges, halting daytime road and rail traffic. KPA forces were forced to hide in tunnels by day and move only at night. To deny military equipment and supplies to the KPA, the USAF destroyed logistics depots, refineries, and harbors, while US Navy aircraft attacked transport hubs. By late August, the Pusan Perimeter had 500 medium tanks battle-ready. In early September 1950, UN forces outnumbered the KPA 180,000 to 100,000 soldiers. The perimeter enclosed about 10% of Korea, and the KPA purged South Korea's intelligentsia by killing civil servants and intellectuals. On the 20th of August, MacArthur warned Kim Il Sung he would be held responsible for KPA atrocities. Kim's early successes led him to predict the war would finish by the end of August, but Chinese leaders were more pessimistic.
The Inchon Landing
On the 15th of September 1950, UN forces landed at Inchon near Seoul, cutting off KPA troops and supply lines. The amphibious landing was recommended by General Douglas MacArthur, who ordered Major General Hobart R. Gay, commander of the US 1st Cavalry Division, to plan an amphibious landing at Inchon. The Pentagon opposed him, but when authorized, he activated a combined US Army and Marine Corps, and ROK force. The X Corps, consisted of 40,000 troops of the 1st Marine Division, the 7th Infantry Division and around 8,600 ROK soldiers. By the 15th of September, the amphibious force faced few KPA defenders at Inchon: military intelligence, psychological warfare, guerrilla reconnaissance, and protracted bombardment facilitated a light battle. However, the bombardment destroyed most of Incheon. The breakout from the Pusan Perimeter began on the 16th of September, with Task Force Lynch, 3rd Battalion, 7th Cavalry Regiment, and 70th Tank Battalion units advancing through of KPA territory to join the 7th Infantry Division at Osan on the 27th of September. X Corps rapidly defeated the KPA defenders around Seoul, thus threatening to trap the main KPA force. On the 25th of September, Seoul was recaptured by UN forces. US air raids caused heavy damage to the KPA, destroying most of its tanks and artillery. KPA troops in the south, instead of effectively withdrawing north, rapidly disintegrated, leaving Pyongyang vulnerable. During the retreat, only 25,000-30,000 KPA soldiers managed to reach the KPA lines.
The Chinese Intervention
On the 19th of October 1950, the Chinese People's Volunteer Army crossed the Yalu and entered the war on the side of the North. The PVA marched dark-to-dark, from 19:00 to 03:00, and aerial camouflage was deployed by 05:30. During daylight activity or marching, soldiers remained motionless if an aircraft appeared; PVA officers were under orders to shoot security violators. Such battlefield discipline allowed a three-division army to march the from An-tung, Manchuria, to the combat zone in 19 days. Another division night-marched a circuitous mountain route, averaging daily for 18 days. After secretly crossing the Yalu River on the 19th of October, the PVA 13th Army Group launched the First Phase Offensive on the 25th of October, attacking advancing UN forces near the Sino-Korean border. This decision made solely by China changed the attitude of the Soviet Union. Twelve days after PVA troops entered the war, Stalin allowed the Soviet Air Forces to provide air cover and supported more aid to China. After inflicting heavy losses on the ROK II Corps at the Battle of Onjong, the first confrontation between Chinese and US military occurred on the 1st of November 1950. Deep in North Korea, thousands of soldiers from the PVA 39th Army encircled and attacked the US 8th Cavalry Regiment with three-prong assaults, from the north, northwest, and west, and overran the defensive position flanks in the Battle of Unsan. On the 13th of November, Mao appointed Zhou overall commander and coordinator of the war effort, with Peng Dehuai as field commander. On the 25th of November, on the Korean western front, the PVA 13th Army Group attacked and overran the ROK II Corps at the Battle of the Ch'ongch'on River, and then inflicted heavy losses on the US 2nd Infantry Division on the UN forces' right flank. Believing they could not hold against the PVA, the Eighth Army began to retreat, crossing the 38th parallel in mid-December.
The Stalemate
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 UN bombing. For the rest of the war, the UN and the PVA/KPA fought but exchanged little territory. Large-scale bombing of North Korea continued, and protracted armistice negotiations began on the 10th of July 1951 at Kaesong in the North. On the Chinese side, Zhou directed peace talks, and Li Kenong and Qiao Guanghua headed the negotiation team. Combat continued; the goal of the UN forces was to recapture all of South Korea and avoid losing territory. The PVA and the KPA attempted similar operations and later effected military and psychological operations to test the UN Command's resolve to continue the war. The sides constantly traded artillery fire along the front, with American-led forces possessing a large firepower advantage over Chinese-led forces. In the last three months of 1952 the UN fired 3,553,518 field gun shells and 2,569,941 mortar shells, while the communists fired 377,782 field gun shells and 672,194 mortar shells: a 5.8:1 ratio. The communist insurgency, reinvigorated by North Korean support and scattered bands of KPA stragglers, resurged in the south. In the autumn of 1951, Van Fleet ordered Major General Paik Sun-yup to break the back of guerrilla activity. The UN's limited offensive to shorten and straighten sections of the lines, acquire better defensive terrain, and deny the enemy key vantage points, saw heavy fighting by UN forces, with I Corps and X Corps making limited tactical advances against PVA and KPA forces. The campaign resulted in approximately 60,000 casualties, including 22,000 Americans. The intense battles at Bloody Ridge, the Punchbowl and Heartbreak Ridge underscored the challenges of penetrating the Chinese active defense. Despite PVA/KPA losses of 100,000, 150,000 troops, these were not crippling, and the PVA forces remained resolute. By November, the UNC abandoned major offensive operations, and the PVA launched counterattacks with some success.
The Armistice
Combat ended on the 27th of July 1953 with the signing of the Korean Armistice Agreement, which allowed the exchange of prisoners and created a Demilitarized Zone (DMZ) along the frontline, with a Joint Security Area at Panmunjom. The conflict caused around one million military deaths and an estimated one and a half to three million civilian deaths. Alleged war crimes include the mass killing of suspected communists by Seoul and the mass killing of alleged reactionaries by Pyongyang. North Korea became one of the most heavily bombed countries in history, and virtually all of Korea's major cities were destroyed. No peace treaty has been signed, making the war a frozen conflict. The armistice negotiations had begun in July 1951, but dragged on as the fighting became a war of attrition and the North suffered heavy damage from UN bombing. The Chinese had success in penetrating South Korean lines but failed to capitalize, particularly when US forces responded with overwhelming firepower. Chinese casualties in their final major offensive (above normal wastage for the front) were about 72,000, including 25,000 killed compared to 14,000 for the UN (most were South Koreans, 1,611 were Americans). The armistice agreement marked the end of active combat, but the conflict remained unresolved, with the Korean Peninsula still divided and the potential for future conflict ever-present.
