On August 4, 1964, the captains of two American destroyers, the USS and the USS , reported that their ships were being attacked by North Vietnamese torpedo boats. This report came on top of a previous report by the captain of the USS , indicating that he had been attacked by torpedo boats two nights earlier. The text introduces readers to the historiography of these incidents and how the perception of the events changed over time. The attacks, which were collectively called the Gulf of Tonkin incident, are presented in the context not only of the Vietnam War but also of the Cold War and U.S. government powers, enabling students to understand the events’ full ramifications. Using essential primary documents, Tal Tovy provides an accessible introduction to a vital turning point in U.S. and international affairs. This book will be useful to all students of the Vietnam War, American military history, and foreign policy history.
