 On the morning of 2 August 1964, the morning after OPLAN commandos raided a North Vietnamese radio transmitter located on an offshore island, one of these destroyers, the USS "Maddox", was reported to have come under attack by DRV naval patrol boats in the Gulf of Tonkin.There was a second alleged attack on August 4, which was later shown to be a falsehood.These attacks, and the ensuing naval actions, known as the Gulf of Tonkin Incident, were seized upon by President Lyndon Johnson to secure passage by the U.S. Congress of the Southeast Asia Resolution (better known as the Gulf of Tonkin Resolution) on 7 August 1964, leading to a dramatic escalation of the Vietnam War.
