Prange,
At Dawn We Slept:
"[General] Marshall's 'aide memoire' concluded: 'In point of sequence, sabotage is first to be expected, and may, within a very limited time cause great damage.
On this account, and in order to insure strong control, it would be highly desirable to set up a military control of the islands prior to the likelihood of our involvement in the Far East.' "
Prange commenting: "The Chief of Staff expected widespread sabotage in Hawaii as a fact beyond dispute.
This in turn indicated he expected one of two things:
- Either a general advance warning, such as a formal declaration of war, at which signal thousands of Hawaii's Japanese would spring into action, or
- Tokyo's coordination of an attack with local brethren."
Here we see one root-cause of Hawaii's Army commander, General Short's, response to the various "war warnings" he will receive before December 7.
