Final answer:
The recapturing of the South Korean capital by U.S. and Republic of Korea forces following the Inchon landing signifies a turning point in the Korean War, orchestrated by General Douglas MacArthur's Inchon Invasion.
Step-by-step explanation:
Following the Inchon landing, U.S. and Republic of Korea (ROK) forces recaptured the South Korean capital from the North Koreans. This is an example of a turning point in the Korean War. After the initial invasion of South Korea by the North Korean People's Army, the United Nations, with the U.S. taking a leading role, established a defense in the southern part of the country, known as the Pusan Perimeter. General Douglas MacArthur masterminded the Inchon Invasion, an amphibious assault which successfully overwhelmed North Korean forces and reclaimed Seoul. The operation not only liberated the South Korean capital but also cut North Korean supply lines and led to a dramatic shift of momentum in favor of UN forces. MacArthur's forces then continued to push the North Korean troops back across the 38th Parallel.
