On 30 November 2005, the National Security Agency (NSA) released the first installment of previously classified information regarding the Vietnam era, specifically the Gulf of Tonkin incident. This release includes a variety of articles, chronologies of events, oral history interviews, signals intelligence (SIGINT) reports and translations, and other related memoranda. On 30 May 2006, NSA released the second and final installment of Gulf of Tonkin materials. This final release includes additional articles, chronologies of events, oral history interviews, and other related memoranda. The opinions expressed within the documents in both releases are those of the authors and individuals interviewed. They do not necessarily represent the official views of the National Security Agency. The Gulf of Tonkin incident, like others in our nation's history, has become the center of considerable controversy and debate. It is not NSA's intention to prove or disprove any one set of conclusions, many of which can be drawn from a thorough review of this material. Instead, through these public releases, we intend to make as much information as possible available for the many scholars, historians, academia, and members of the general public who find interest in analyzing the information and forming their own conclusions. The site includes: Chronologies of Events; Miscellaneous Memoranda and Notes; Material relating to proposed "History of Southeast Asia" article by NSA Historian William Gerhard, circa 1972; Articles; Oral History Interviews; Signals Intelligence (SIGINT) Reports (R) and Translations (T) Mar 64 - Oct 64 ; Related Command and Technical Messages from 02 Aug 64 to 26 Aug 64.
