1st Marine Division (Reinforced)

        This division was stationed at Camp Pendleton, California having previously served as an occupation force in North China from September 1945 to June 1947. It was brought up to war strength mainly with reservists.

        The Division departed for Korea between 10-22 August 1950, minus 7th Marines, which departed on 3 September 1950. Lead elements of the 1st Marines and support units arrived in Japan in early September 1950.

        The bulk of the Division landed in Korea on 15 September and regained control of the former 1st Provisional Marine Brigade elements, which rejoined the Division by sailing directly from Pusan, South Korea. It was joined by 7th Marines on 21 September 1950.

        The Division was relieved by 25th Infantry Division and returned to Camp Pendleton, California in April 1955. The associated 1st Marine Aircraft Wing redeployed to Japan at the same time.
