Signifi cant Information Known in Washington 237
Th e volume of Japanese intercepts being decoded and translated
in Washington during this time was almost overwhelming.
Th e purpose of such cryptanalysis is, of course, to use the intelligence
eff ectively to gain an advantage over one’s adversaries. Th e
record reveals that our cryptanalysts and translators were doing
a remarkable job; they were intercepting, decoding, translating,
and disseminating promptly countless Japanese messages. Th us, a
great deal of information was coming into Washington. However,
precious little “intelligence” was going out—to the men in the
fi eld who might have been able to use it.
