Of the many facets of the American war in Southeast Asia debated by U.S. authorities in Washington, by the military services and the public, none has proved more controversial than the air war against North Vietnam. The air war s inauguration with the nickname Rolling Thunder followed an eleven-year American effort to induce communist North Vietnam to sign a peace treaty without openly attacking its territory. Thus, Rolling Thunder was a new military program in what had been a relatively low-key attempt by the United States to win the war within South Vietnam against insurgent communist Viet Cong forces, aided and abetted by the north. The present volume covers the first phase of the Rolling Thunder campaign from March 1965 to late 1966. It begins with a description of the planning and execution of two initial limited air strikes, nicknamed Flaming Dart I and II. The Flaming Dart strikes were carried out against North Vietnam in February 1965 as the precursors to a regular, albeit limited, Rolling Thunder air program launched the following month. Before proceeding with an account of Rolling Thunder, its roots are traced in the events that compelled the United States to adopt an anti-communist containment policy in Southeast Asia after the defeat of French forces by the communist Vietnamese in May 1954.

This is the second volume in a series of chronological histories prepared by the Marine Corps History and Museums Division to cover the entire span of Marine Corps involvement in the Vietnam War. This volume details the Marine activities during 1965, the year the war escalated and major American combat units were committed to the conflict. The narrative traces the landing of the nearly 5,000-man 9th Marine Expeditionary Brigade and its transformation into the ΙII Marine Amphibious Force, which by the end of the year contained over 38,000 Marines. During this period, the Marines established three enclaves in South Vietnam’s northernmost corps area, I Corps, and their mission expanded from defense of the Da Nang Airbase to a balanced strategy involving base defense, offensive operations, and pacification. This volume continues to treat the activities of Marine advisors to the South Vietnamese armed forces but in less detail than its predecessor volume, U.S. Marines in Vietnam, 1954-1964; The Advisory and Combat Assistance Era.
