this is a sympathy four-stars... Frank doesn't actually deserve incredibly good reviews for his writing ability, but what he did is uncover old US military archives and old Imperial Japanese documents to show just how bloody the Battle of Kyushu would have been had it been fought-- lots of underestimation on the US war planners for how many troops
so although there is no amazing literary performance on Frank's part, the work does bring into public eye information that would have otherwise been locked up in dusty military libraries somewhere, and historians, of course, should be praised even if that is all they do.
