While Professor Gannon (Distinguished Service Professor Emeritus of History at the University of Florida) has now shifted his interest and research focus to the early history of Florida, he remains best known for his work on German U-boats of WWII (Operation Drumbeat), and investigating the issue of the effectiveness of aerial reconnaissance at Pearl Harbor (e.g., Dorn Report).

This book is a valuable addition to our better and fuller understanding of Pearl Harbor. Its logical structure, crisp writing, and expertisely developed train of citations offer the reader a journey that is rewarded by its "let you decide" conclusion.

Some of the more intrinsical materials Professor Gannon uses are from newly released documents; but much comes from the earlier Pearl Harbor investigations and documents from that period, particularly the Martin-Bellinger report.

For example, note 78 from "Chapter Six: War Warning" has Seth Richardson's comments:

"It was well known and recognized in Washington for at least a year prior to 7 December 1941 that adequate protection of the fleel in Hawaii, where Washington ordered it to base rather than on the west coast, depended on having an adequate number of patrol and bomber planes with which to maintain reconnaissanace and to defeat any approaching attacking force; that during the year 1941 there were manufactured in the United States a very large number of patrol and bomber planes, of which only a few were sent to Hawaii while a large and dispportionate number were diverted by Washington to Great Britain, in many instances under lend-lease; ..."

[N.B., Lend-Lease records show that over 200 PBYs went to Great Britain in 1941. Harry Hopkins, personal advisor to FDR, was the Director of the Lend-Lease Program at this time. Also, Great Britain received US built PURPLE machines and Pearl Harbor did not received a one.]

Another example, from the Epilogue, is note 56, of interest to the "pied piper" of Prange and associates and their ageing lemmings:

"Ibid., p. 344. Use of the language 'most dangerous sectors' reminds one of the historian Gordon W. Prange, on two counts. First, because, as Prange wrote, the Martin-Bellinger estimate of 31 March 1941 was an 'historic work' 'famous to all students of the Pacific war," At Dawn We Slept, p.93. Second, because he (or his two collaborators) wrote that the Martin-Bellinger estimate of 31 March 1941 postulated that the "most dangerous sectors" from which an air attack on Pearl might be mounted were "the north and northwest." Gordon W. Prange, with Donald M. Goldstein and Katherine V. Dillon, Pearl Harbor: The Verdict of History (New York: McGraw-Hill Company, 1986), p.411. But Martin-Bellinger states no such thing; the text can be found in three places in the JCC record: Pt. 1, pp. 379-82; Pt. 22, pp. 349-54; and Pt. 33, pp. 1182-86. It appears that the 'famous historic' is also an unread work. ..."

As more Pearl Harbor material continue to be released, now even with some original documents coming from private hands, it is fitting to recognize Professor Gannon ending sentence.

"Truth is the daughter of time."
