This publication represents the eighth volume in an operational and chronological series covering the Marine Corps' participation in the Vietnam War. This particular volume details the gradual withdrawal in 1970-1971 of Marine combat forces from South Vietnam's northernmost corps area, I Corps, as part of an overall American strategy of turning the ground war against the North Vietnamese and Viet Cong over to the Armed Forces of the Republic of Vietnam. Although written from the perspective of III MAF and the ground war in I Corps, the volume treats the activities of Marine advisors to the South Vietnamese Armed Forces, the Seventh Fleet Special Landing Force, and Marines on the staff of the U.S. Military Assistance Command, Vietnam, in Saigon. There are separate chapters on Marine air, artillery, and logistics. An attempt has been made to place the Marine role in relation to the overall effort.
