In 1994, Secretary of War Henry L. Stimson, knowing that high-ranking members of the American military had testified falsely before the various bodies investigating the sneak attack on Pearl Harbour, selected a lowly major and young lawyer named Henry C. Clausen and gave him extraordinary authority to go anywhere and question anyone under oath, from enlisted personnel right up to Chief of Staff George C. Marshall. To this day, no member of the public knows the full story of Clausen's investigation. Over seven months during 1944 and 1945, Clausen travelled more than 55,000 miles to interview and obtain sworn affidavits from nearly 100 Army, Navy civilian and British personnel. Henry Clausen is the last major living witness and this book, written by Clausen, reveals the truth about Pearl Harbour.
