This is the ninth volume in a nine-volume operational and chronological historical series covering the Marine Corps' participation in the Vietnam War. A separate functional series complements the operational histories. This volume details the final chapter in the Corps' involvement in Southeast Asia, including chapters on Cambodia, the refugees, and the recovery of the container ship SS Mayaguez. In January 1973, the United States signed the Paris Peace Accords setting the stage for democracy in Southeast Asia to test its resolve in Cambodia and South Vietnam. The result was not a rewarding experience for America nor its allies. By March 1975, democracy was on the retreat in Southeast Asia and the U.S. was preparing for the worst, the simultaneous evacuation of Americans and key officials from Cambodia and South Vietnam. With Operation Eagle Pull and Operation Frequent Wind, the United States accomplished that task in April 1975 using Navy ships, Marine Corps helicopters, and the Marines of the III Marine Amphibious Force. When the last helicopter touched down on the deck of the USS Okinawa at 0825 on the morning of 30 April, the U.S. Marine Corps' involvement in South Vietnam ended, but one more encounter with the Communists in Southeast Asia remained. After the seizure of the SS Mayaguez on 12 May 1975, the United States decided to recover that vessel using armed force. Senior commanders in the Western Pacific chose the Marine Corps to act as the security force for the recovery. Marines of 2d Battalion, 9th Marines and 1st Battalion, 4th Marines played a key role in the events of 15 May 1975 when America regained control of the ship and recovered its crew, concluding American combat in Indochina and this volume's history. Although largely written from the perspective of the III Marine Amphibious Force, this volume also describes the roles of the two joint commands operating in the region: the Defense Attache Office, Saigon, and the United States Support Activities Group, Thailand. Thus, while the volume emphasizes the Marine Corps' role in the events of the period, significant attention also is given to the overall contribution of these commands in executing U.S. policy in Southeast Asia from 1973 to 1975. Additionally, a chapter is devoted to the Marine Corps' role in assisting thousands of refugees who fled South Vietnam in the final weeks of that nation's existence.

This is the ninth volume in a nine-volume operational and chronological series covering the Marine Corps' participation in the Vietnam War. This volume details the final chapter in the Corps' involvement in Southeast Asia, including chapters on Cambodia, the refugees, and the recovery of the container ship SS Mayaguez.
