Gulf of Tonkin Incident 1964

North Vietnamese torpedo boats reportedly made two sets of attacks on American vessels in the Gulf of Tonkin, off Vietnam (August 2 and 4). It was the basis of the Tonkin Gulf Resolution, committing major American forces to the Vietnam War, though some critics later questioned the facts. By year's end, 20,000 to 25,000 American troops and hundreds of American warplanes were in Vietnam.

Tonkin Gulf Resolution (August 7): American congressional resolution, passed in the House unanimously and in the Senate with only two dissenting votes, authorized President Lyndon B. Johnson to take the United States into the undeclared Vietnam War, which he immediately did. The authorization was granted after reported North Vietnamese torpedo boat attacks on two American naval vessels in the Gulf of Tonkin; the reports were later the subject of great controversy.

Armed Conflict Events Database

Armed Conflict Events Data (ACED) is an research project providing independent information about known wars, international disputes, civil wars, rebellions, coups, revolutions, genocides and other violent conflicts. ACED has been online since December 2000. Various partial revisions and modifications have been implemented since then, however, the limitations of the this format hamper further development. During 2005, the decision was made to radically restructure the available conflict information into a database. The new Armed Conflict Events Database (ACEDb) will substantially increase the utility of available conflict data for students of military history. As well, it will offer expanded opportunities to add and edit records of conflict. Existing research material will be maintained in its present form but no revisions are planned. More news about the development of ACEDb may be found at News About the Armed Conflict Events Database. Feedback is welcome.
