On the night of August 4, 1964, the U.S. Navy destroyers Maddox and Turner Joy reported that they were being attacked by North Vietnamese torpedo boats in the Gulf of Tonkin. Within hours, President Lyndon Johnson ordered the first U.S. airstrikes against North Vietnam. On August 7, Congress passed the Tonkin Gulf Resolution, which gave the President authority to take "all necessary measures" to prevent further aggression. Johnson later cited this as authorizing the massive escalation of the war that he began in 1965.
Almost everyone on the two destroyers believed, during the incident, that they were under attack. Some still believe so, while others have since decided that what had appeared on radar screens as torpedo boats had actually been false images generated by weather conditions, birds, or American planes overhead. Consideration of all of the evidence--the testimony of U.S. personnel from the two destroyers and of pilots who were overhead, declassified U.S. records, communications intercepts, interrogation of North Vietnamese torpedo boat personnel captured later in the war, etc.--leads to a clear conclusion: there was no attack. But the original report of an attack was not a lie concocted to provide an excuse for escalation; it was a genuine mistake.
Previous studies of the Tonkin Gulf Incidents had been based either on extensive interviewing of participants, or on the use of U.S. government records; this is the first study to combine both these sorts of evidence. It is also the first to make significant use of Vietnamese sources. These tell little about August 4, since no Vietnamese were anywhere near the two destroyers during the supposed incident that night, but they do much to illuminate events before and after August 4, including the genuine battle between the destroyer Maddox and three torpedo boats on August 2, which helped set the stage for the imagined attack of August 4 by leaving U.S. sailors with an expectation that North Vietnamese torpedo boats were likely to attack them.
The most important new material in the revised edition comes from documents released by the National Security Agency in 2005 and 2006. These documents show that signals intelligence (SIGINT) did not give the Americans nearly as good an understanding of enemy actions as one might have expected. The Americans had not been listening to North Vietnamese Navy communications long enough to have learned a lot about the North Vietnamese Navy. They could intercept and decode North Vietnamese messages, but their ability to understand those messages, and put them in context, was surprisingly limited.

p. 197, last four sentences: This story of how a crucial German signal was misinterpreted by the British just before the Battle of Jutland, in 1916, was long accepted in the history of that battle. A recent study by Jason Hines, "Sins of Omission and Commission: A Reassessment of the Role of Intelligence in the Battle of Jutland," Journal of Military History, October 2008, pp. 1127-29, argues that this story is untrue. I do not find Hines' argument fully convincing, but I take it seriously enough so I would not, today, simply present the traditional story as accepted fact.
p. 261, note 7: "p. 113" should be "p. 116"
My photographs of torpedo tubes from a North Vietnamese PT boat, of the unit that was involved in the first Tonkin Gulf Incident. These photos were conspicuously displayed at a museum in Hanoi when I photographed them in 1989. I was told some years later that they were no longer there. But when I went again in 2013, they were again on display, though in a less conspicuous location than before.
