The Board interpreted these orders and the memorandum referred to as
confining its investigation to the Pearl Harbor disaster.
The Board convened 20 July 1944 and was in continuous session from 24 July 1944 to 20 October 1944. It held hearings twice in Washington, D.C.; twice in San Francisco, California; and in Hawaii. It has heard a total of 151 witnesses and has interviewed many additional potential witnesses whom it found did not have any pertinent information. There has been no available document, witness, suggestion or lead which promised any materiality that has not been carefully investigated by this Board. Every witness has been invited to give, in addition to his testimony, any suggestions, opinions, leads to evidence, or any other information that might possibly be pertinent. It has been our purpose, and we believe we have effected it, to explore every available piece of information on this subject. We have not had the opportunity, nor the organization, to comb personally and exhaustively the official files, but we have called for the pertinent letters, documents, and memoranda. We believe that practically all of them have been secured, although we have found a few files from which important and vital papers are missing. In many instances we found these document s elsewhere or were
able to prove them through copies in other hands.
