USA HISTORY

Detailed explanation-1: -After the front stabilized at the Pusan perimeter, General MacArthur surprised the North Koreans in September 1950 with an amphibious landing at Inchon behind North Korean lines, forcing the North Koreans to retreat behind the 38th parallel.

Detailed explanation-2: -After North Korea invaded South Korea on June 25, 1950, MacArthur was appointed supreme commander of the U.S.-led U.N. force sent to aid the South. In September, he organized a risky but highly successful landing at Inchon, and by October North Korean forces had been driven back across the 38th parallel.

Detailed explanation-3: -MacArthur felt that he could turn the tide if he made a decisive troop movement behind KPA lines, and preferred Incheon, over Chumunjin-up or Kunsan as the landing site. He had originally envisioned such a landing, code-named Operation Bluehearts, for 22 July, with the US Army’s 1st Cavalry Division landing at Incheon.

Detailed explanation-4: -By the early evening, the Marines had overcome moderate resistance and secured Inchon. The brilliant landing cut the North Korean forces in two, and the U.S.-led U.N. force pushed inland to recapture Seoul, the South Korean capital that had fallen to the communists in June.
