Walter Karig has done a superb job in his five volume Battle Report now completed. This book is an independent work, and tells the story of the submarine fighters of World War II. An excellent, overall picture of convoy duty and weather reporting in the North Atlantic; pre-attack periscope reconnaissance and photography along the coasts of North Africa, among the islands of the South Pacific, and in the imperial waters of Japan itself; the development of its use as rescue medium for pilots and refugees stranded in odd corners of the Philippines and Eest Indies; mine sowing; and finally the formation of wolf packs. After a discussion of the history and particulars of undersea craft that is not too technical for the average layman, the authors illustrate each facet of the submarine's war role with an incident from World War II. There is a summary at the close of post war developments, and the probable role of the submarine in the future. Broader gauged than Admiral Lockwood's (see report P. 43). This is a general coverage, while that is based on personal experience of one special area.
