The following summarization has been prepared on the basis of
reliable information obtained from various sources subsequent to the
attack on Pearl Harbor. Although this summary does not represent a
resume of Japanese Combined Fleet Operation Order No. 1, it will be
apparent that heavy reliance has nevertheless been placed upon that
document, a translation of which is submitted under separate cover.
The Japanese Naval High Command completed preparations during
the summer and fall of 1941 to carry out a projected 2-phase plan of
conquest and consolidation in the Asiatic-Pacific theatre. The essence
of the plan lay in the element of surprise in a sudden attack which at
one fell swoop would cripple the major potential opposition - the American
Fleet maintained at Pearl Harbor. Following the crippling of this op-
position weapon, coincident with the seizure and occupation of land masses
desired for the economic), political, and military reasons that together
determined the borders of the Greater East Asia Co-Prosperity Sphere,
Phase 1 of the campaign would be completed, and Phase 2 - the consoli-
dation of these gains by the seizure or neutralization of outer areas,
together with the continued attrition of the enemy forces and his lines
of supply - could be carried out to ensure the permanence of the new Empire.
The Japanese fleet, which had been in training over a period of
years for combat fleet operations, was in a state of readiness by the
summer of 1941. By late August of 1941, there is evidence based on in- -
formation believed to be reliable, that the Commander in Chief of the
Combined Fleet ordered all fleet commanders and their key staff members
