Thank you Ed and Martin for the additional details. After your insight plus the Stone & Stone review, it is much, much more similar to Jurgen Rohwer's excellent
Chronology of the War at Sea, 1939-1945: The Naval History of World War Two, than it is to the Samuel Eliot Morison history.
Rohwer, of course, is in print and on the internet (
https://www.wlb-stuttgart.de/seekrieg/chronik.htm#Z ) and I always thought this was packed with an incredible amount of detail. Before buying, I think I might want to compare Rohwer and this new series of books to see if the additional detail justifies the expenditure. That said, I wish the authors Bertke, Kindell and Smith all the best but I am sure they and the publishers they may have gone to would make this comparison and this would have an impact on sales.
