1. Kim Il-Sung's invasion of South Korea across the 38thparallel on 25th June 1950
2. UN Security Council voted to take military action to help SouthKorea on 27thJune1950
3. Soviet Union supported North Korea but was not present at the UN meeting to veto the decision
How the UN army attack at Inchon led to an international crisis
1. Superiornavalsupport for UNtroops, majority were UStroops with previous beachstormingexperience from WW2
2. Strategic decision to target Inchon as it was strongly fortified but not heavily defended by North Korean forces
Kim Il-Sung realised that his tactic of encouraging guerilla warfare in the south wasn't enough to destabilise the government, so he thought an invasion might trigger an uprising in the South, overthrowing the ROK
The UN troops captured the entirety of Inchon in 4 days
The UN troops targeted Inchon as it was strongly fortified, which meant it wasn't an obvious target and wasn't heavily defended by North Korean forces
Outbreak of the Korean War
1950
By 1950, North Korea had 135,000 troops while the South had 19,000 troops
There were problems with the election as the Soviet Union refused to allow UN inspectors into North Korea
Only southern voters were counted in the election
After the establishment of the two governments, the Soviets and the USA withdrew their troops from Korea
The two Korean governments refused to accept the legitimacy of the other
Korean War
1950-1953
In 1945, when the Allies defeated Japan in WWII, the Japanese Army was dismantled
America proposed to occupy Korea alongside the Soviet Union, with the Soviet Union occupying the North and the USA occupying the South
The division of Korea along the 38th parallel was intended to prevent further conflict between US and Soviet troops
The Korean people were unhappy under Japanese control and wanted immediate independence, but there was a real divide within Korea on how to go about this
The USA and USSR had very different ideologies and both sides competed for influence in Korea
The USA was deeply concerned by the threat of communism in Korea and wanted to stop it from gaining a foothold and potentially spreading to other countries
In 1948, the USA called on the UN for help, and the UN declared that national elections should be held in Korea the following year
Stalemate
Both sides were facing each other on heavily fortified positions over the par, with no clear progress
Airpower used to break stalemate
1. US planes began bombing North Korean towns, cities, transport systems, factories and many bases with high explosives and napalm
2. Many Korean people, both soldiers and civilians, were killed
Soviet Involvement
Chinese politicians had met with Stalin, the Soviet leader, to ask for his support
Stalin agreed to send military equipment and aviation to help the Chinese and North Korean forces
Stalin stipulated that Soviet fighter planes (and pilots) would only operate over Chinese airspace, and around the Chinese-North Korean border
Soviet cover-up of involvement
Soviet planes were painted with Chinese or North Korean markings and Soviet pilots were banned from speaking Russian on the radio
For almost two years the two sides fought each other in the air over Korea
The UN lost around 3500 planes while the North Koreans, Chinese and Soviets lost nearly 3000
Some pilots even wore Chinese uniforms during combat missions
North Korea's forces pushed the South Korean army back to Pusan
UN troops launched an attack at Inchon
Then pushed inland
UN forces and South Korean troops in the south advanced
North
By early December, all North Korean troops had been driven out of South Korea. UN forces crossed into North Korea
China warned against the advance
But MacArthur was confident China would not enter the war
In late October 1950, China joined the war
And helped push UN forces back into South Korea
By March 1951, the advance had been stopped with both sides around the 38th parallel
Against orders from Truman, MacArthur sent UN troops back into North Korea
MacArthur was sacked
The UN and the war in Korea was largely American, with the USA providing most of the troops and equipment
US forces were led by an American General, MacArthur
The UN approved the action of crossing the 38th parallel into North Korea, hoping that North and South Korea could be unified
When UN troops began driving North Korean forces back towards the Yalu River on the Chinese border
Around 200,000 Chinese troops joined the North Koreans to fight back
Chinese and North Korean forces pushed the UN forces back into South Korea, and re-took Seoul
