What is the assessment of Sumida's naval-history books?
Short answerThey are judged good overall, with less agreement about Arthur Pollen and no confidently identified book singled out.
NotesSumida's work receives a favourable overall assessment, with a reservation about the enthusiasm shown for Arthur Pollen. Agreement with an author's overall contribution does not require agreement with every interpretation. The discussion hesitates over particular books and where they are on the shelves, so it does not establish a reliable title-specific recommendation.
