This is the eighth volume of a projected nine-volume history of Marine Corps operations in the Vietnam War. A separate functional series complements the operational histories. This volume details the activities of Marine Corps units after the departure from Vietnam in 1971 of Ill Marine Amphibious Force, through to the 1973 ceasefire, and includes the return of Marine prisoners of war from North Vietnam. Written from diverse views and sources, the common thread in this narrative is the continued resistance of the South Vietnamese Armed Forces, in particular the Vietnamese Marine Corps, to Communist aggression. This book is written from the perspective of the American Marines who assisted them in their efforts. Someday the former South Vietnamese Marines will be able to tell their own story. By July 1971, less than 500 U.S. Marines, mostly advisors, communicators, and supporting arms specialists remained in Vietnam. It was thought at the time that the success of "Vietnamization" of the war would lessen even this small number, as it was hoped that the South Vietnamese could continue fighting successfully. This hope vanished in spring 1972, dashed by a full-scale North Vietnamese Army invasion. The renewed combat saw the U.S. Marines return once more to Southeast Asia in a continuation of the war that now seemed to have no end. The fighting proceeded into the fall, and only ceased with the signing of peace accords in Paris in January 1973.
