  1. Overview • Understand the historical background and underlying causes of the Korean War • Know the significant events which shaped the outcome of the Korean War

  2. Potsdam Conference (July 16 to Aug 2, 1945) • At Potsdam that the allies decided, without consulting the Koreans, to divide the peninsula at the 38th Parallel. American Lt. General John R. Hodge following surrender of Japan was appointed military governor of South Korea Hodge established control by restoring power to key Japanese colonial administrators and their Korean police collaborators. • In December 1945, Korea was administered by a US–USSR Joint Commission. It was decided the country would become independent after a five-year trusteeship action. • This provoked civil unrest and even guerilla warfare, resulting in further crackdowns. Civil disorder spread throughout the country in what became known as the Autumn uprising.

  3. Road to Separation • Anti-Communist nationalist leader Syngman Rhee, opposed the Soviet–American trusteeship of Korea arguing it was just another foreign occupation • On November 14, 1947 the United Nations passed UN Resolution 112, calling for a general election under the supervision of the UN Commission. The Soviet Union refused to comply with the UN resolution and denied the UN Commission access to the northern part of Korea. U.S. backed South Korea decided to forego the five year trusteeship agreed and planned for elections in May 1948.

  4. Road to Separation • The South Korea elections resulted in a constitution and president, Syngman Rhee. • The Republic of Korea(South Korea) was officially established on August 15. Rhee purged the Communists in the south , many of whom headed north to prepare for war. • North Korea held parliamentary elections on August 25, 1948. On September 9, the communist Democratic People's Republic of Korea (North Korea) was proclaimed, led by former anti-Japanese guerilla fighter Kim Il-Sung.

  5. Road to War • In early 1949, the U.S. began to disengage from Korea in every way. • Undersecretary of State Acheson, stated publically that South Korea was not a vital part of the U.S. defense perimeter in Asia. The U.S. military withdrawal was completed by June 1949, with only 500 military advisors remaining behind. • Both Kim Il-Sung and Syngman Rhee wanted to unify the Korean peninsula under their rule and ideology. • The U.S. Congress became nervous that if too much military aid was given to South Korea, Rhee would use it to invade the North, hence the U.S. only provided South Korea light arms and armor only, withholding heavy tanks and aircraft.

  6. Korean War: Phase I • June 25, 1950: North Korean forces crossed the 38th Parallel and attacked South Korea. The United Nations Security Council condemned the invasion. • On June 26th, North Korean tanks reached the outskirts of Seoul. • Test of the Truman Doctrine and Domino Theory • The US immediately began using air and naval forces and initially believed they would be enough to stop North Korean forces. • The U.S. refrained from sending ground troops for fear that the North Korean attack might be a diversionary tactic to engage America in Korea, leaving the Soviets free to attack somewhere else. • Once the Soviet Union suggested it would not move against the deployment of US ground forces in Korea, the U.S. committed ground forces

  7. Korean War: Phase I • Hampered by lack of communications equipment and shortages of heavy weapons, U.S./ROK forces were pushed back • August 4, 1950: The Battle of Pusan Perimeter began. From Aug 4 to Sept15, the US Army withstood numerous attacks. The USAF interrupted enemy movements by destroying 32 bridges and bombing convoys, halting most daytime road and rail traffic and forcing the North Korean to move supplies only at night.

  9. Korean War: Phase II • Inchon: September 15, 1950: To relieve pressure on Pusan, General MacArthur launched an ingenious amphibious assault on the West Coast of South Korea, at Inchon, a hundred miles away from Pusan. • From Inchon, American units moved both Northward, through the 38th Parallel, and southwest to effect of relief of the forces at Pusan. • October 15, 1950: Truman and MacArthur met at Wake Island for a meeting, MacArthur insisted there was little risk of Chinese intervention in Korea. However, on that same day, Chinese forces secretly crossed the Yalu River into North Korea.
