This title is highly recommended.
The book starts with a brief overview of the convoy system, then moves on to an analysis of the various developments in anti-submarine warfare from the beginning of the war up to the time of HX-233's crossing, including the relatively slow realization on the part of the Allies of the immense advantage air cover could lend to their convoy operations.
The author, veteran of many convoys, selected this one for his study for several reasons. First, it had not as yet been fully studied in any other book. Second, it occurred at a critical time during the battle of the Atlantic - April 1943, the month that marked the start of a decline in U-boat successes against convoys. Finally, some chance elements in the interactions of U-boats and convoy, as well as some friction between various members of the combined British-American-Canadian escort group, simply made this encounter an especially interesting opportunity for in-depth exploration.
One of the most valuable aspects of this book (besides the detailed coverage of U-175, mentioned above) is that the author wherever possible uses official documents, eyewitness reports and war diaries from all sides (German, Canadian, British and American) to render as complete and accurate a picture of events as possible. The 15 appendices, glossary, and list of sources, as well as a foreword by Prof Dr Jürgen Rohwer, combine to set the final seal of excellence on this book.
