The Gulf of Tonkin Incident was a pair of alleged attacks by North Vietnamese gunboats on two American destroyers in 1964.

Explanation:

The Gulf of Tonkin Incident involved two alleged attacks by North Vietnam's fleet against two destroyers from the US Navy, the USS "Maddox" and the USS "Turner Joy". The attacks are said to have taken place on August 2 and August 4, 1964 in the Gulf of Tonkin.

The result of the episode was that the US Congress approved the Gulf of Tonkin Resolution, which gave President Lyndon B. Johnson permission to assist any Southeast Asian country whose government was considered threatened by "communist aggression". The resolution served as Johnson's legal basis to escalate America's involvement in the Vietnam War.
