The U.S. X Corps landed at Inchon as part of a meticulously planned operation during the Korean War. General Douglas MacArthur, the commander of UN forces, believed that a successful amphibious assault could turn the tide of the war, which had been favoring North Korean forces. The location of Inchon, with its difficult tides and coastal defenses, posed significant challenges but also offered opportunities to flank North Korean troops who had pushed deep into South Korea.

On the morning of September 15, 1950, naval bombardments from U.S. ships accompanied air strikes from fighter planes, targeting key enemy positions. The initial landings met fierce resistance, but U.S. forces quickly established a foothold. Crude but effective planning allowed the troops to push inland and seize the city of Seoul just a few weeks later, marking a pivotal moment in the conflict.

The success of the Inchon landing reinvigorated UN efforts, allowing for counteroffensive operations that would eventually lead to the recapture of South Korea's capital. However, this operation was not without controversy; it drastically increased the scale of the war and led to further intervention by Chinese forces, altering the course of the Korean War significantly.
