"Statistically, of 1394 wartime commanders of U-Boats commissioned into the Kriegsmarine - including those in training - 847 (60%) failed to sink a single ship."
This comment, a surprising one to me, comes near to the end of this very interesting book and expands to show that 749 U-Boats and 26,791 crewmen were lost in action in WWII. 82 wartime commanders (six per cent) accounted for ten or more vessels destroyed or declared as a constructive loss.
Lawrence Patterson, who has written a number of books on U-Boats, provides a good history of Germany's submarine war globally in WWII. This provides not just information on the main theatre of war with the long-running Battle of the Atlantic, but operations in the Arctic, Mediterranean, the North American/Canadian coastline and down into the Caribbean and the South Atlantic. Moreover, Mr Patterson also gives detail on the East African coast and wider operations in the the mid and South Atlantic. Expanding further, the U-Boat operations for South Africa and into the Indian Ocean are also written about as is the work and connections to the Japanese.
Using operational reports, some first-hand accounts, and an expansive biography from official histories to memoirs by Doenitz and others to secondary sources such as Clay Blair's two volume U-Boat Wars - the operations of the U-Boats is covered from the days prior to war with readiness and initial deployments prior to the attack on Poland to the final days of supporting evacuations of troops and civilians in East Prussia to scuttling and surrender.
This means the reader gains a comprehensive understanding of the construction, design, capability, communications, technology and manpower challenges throughout these years, whilst seeing the operational deployments, tactics and conditions the crew operated to and within. Coupled with the ASW (Anti-Submarine Warfare) operations and tactics and the use of convoys by the allied nations (including but not limited to the UK, Canada, US, Poland, Norway, Denmark, Brazil, NZ, Australia, South Africa) it is apparent that Germany's submariners were overstretched and losing a technology battle from the start.
Yet despite these challenges and threats they carried the war to the allies and created not just destruction and death on the seas but also concern and worry in the capitals and strategic planning operations of Germany's enemies.
There were some printing errors, including two dating mistakes in the footnotes, but this should not detract from a very readable and interesting account. Whilst there were some excellent black and white plates, there was not a single map, which for a publisher of Osprey's quality is very disappointing.
My copy was the hardback version printed in 2022.
