This is the second part of a highly detailed yet accessible two-volume history of America's involvement in Vietnam from the end of World War II through to the Fall of Saigon in 1975.

No Wider War is the second part of a two-volume, accessible narrative history of America's involvement in Indochina from the end of World War II to the Fall of Saigon in 1975. Following on from the first volume, In Good Faith, which told the story from the Japanese surrender in 1945 through America's involvement in the French Indochina War and the initial advisory missions that followed, No Wider War takes up the story from the first deployment of US combat ground troops in March 1965 through to the fall of the South in April 1975.

Drawing on the latest research, unavailable to the authors of the classic Vietnam histories, No Wider War follows the story of America's increasingly heavy commitment to the war from the Marines on the beaches of Da Nang, through the 1st Air Cavalry Division in the Central Highlands, the siege of Khe Sanh, the Tet Offensive of 1968 and the gradual Vietnamisation of the war and draw down of American forces before the final loss of the South in 1975. Examining in depth both the events and the key figures of the conflict, this is a definitive new history of American engagement in Vietnam.
