One page memo from August 1964 stating that the original readiness signal was expanded to include more units.
Only one is readable..others white boxed out.
The memo states “reflections or reactions to the current US/North Vietnamese encounter as well as indications of Chicom actions or intent with
regard to southeast asia will be reported in established vehicles at immediate precedence.”
A very interesting read in regards to the SIGINT documents is the following:
Skunks, Bogies, Silent Hounds, and the Flying Fish:

The Gulf of Tonkin incidents of 2 to 4 August 1964 have come to loom over the subsequent American engagement in Indochina. The incidents,
principally the second one of 4 August, led to the approval of the Gulf of Tonkin Resolution by the U.S. Congress, which handed President Johnson the
carte blanche charter he had wanted for future intervention in Southeast Asia. From this point on, the American policy and programs would dominate the
course of the Indochina War. At the height of the American involvement, over a half million U.S. soldiers, sailors, airmen, and marines would be
stationed there. The war would spread across the border into Cambodia and escalate in Laos. Thailand assumed a greater importance as a base for
supporting the military effort, especially for the air war, but also for SIGINT purposes of intercept and direction finding.
