What event led to the 1964 Gulf of Tonkin Resolution?

The Gulf of Tonkin Resolution followed reports in August 1964 that North Vietnamese torpedo boats had attacked U.S. Navy ships in the Gulf of Tonkin. The second reported attack was disputed and is now widely considered not to have happened. The resolution was passed in response to the alleged attacks on two U.S. Navy ships, not French ships or a ship being sunk or captured.
