Making extensive use of Japanese and U.S. sources, including wartime intelligence reports from the National Defense Archives in Tokyo and recently declassified U.S. documents, this book examines the reasons for Japan's failure to protect its merchant fleet.
Well, if you ever entertained the possibility of an alternate outcome to the Pacific War where the Japanese did better than historically, this book will disabuse you of any such notion.
Winning wars means winning at logistics and the author shows in innumerable ways the hopelessness of the Japanese merchant fleet - especially in organization and protection services.
Although the author cites many Japanese sources and this made the book better than most US centric accounts, one would have wished for more narrative told from the Japanese point of view. Then again, there might not have been too many Japanese merchant captains left by 1945 to tell their stories.
The book is organized into themes. So you'll get a chapter on barges. And a chapter on mine clearing. You get the idea.
