The first United Nations (UN) offensive during the Korean War began on September 15, 1950, with the U.S. X Corps, under Army Maj. Gen. Edward M. Almond, making an amphibious assault at Inchon, 150 miles north from the frontlines. In the south, the Eighth U.S. Army, made up of U.S., ROK, and British forces, counterattacked the next day. The 1st Marine Air Wing provided air support for the landing at Inchon while the Fifth Air Force likewise supported the Eighth Army. On September 16, as part of a strategic bombing campaign, the FEAF bombed Pyongyang, the capital of North Korea, and Wonsan, an east coast port 80 miles north of the 38th parallel.
