Supplementary Investigations:
Clarke, Clausen, Hewitt
Each of the three supplementary investigations was unique.
Th e fi rst of these three supplementary investigations, the
Clarke Investigation, was launched at the request of Army
Chief of Staff Marshall, while the APHB was still under way, to
help him prepare for his next appearance before that board. 1 Th e
second investigation, the Clausen Investigation, was instigated by
Secretary of War Stimson to look into “unexplored leads” in the
Pearl Harbor situation from the Army’s point of view. 2 Th e third
investigation, the Hewitt Inquiry, dealt primarily with the Navy’s
situation and was ordered by Navy Secretary Forrestal who had
found the NCI investigation had not exhausted all possible evidence.
