There is a lot of good information in this book, but I suspect most came from the initial Channel 4 series to which this is a companion. Holden’s writing seems rushed, to the point of slapdash at times. The proofreading and editing process by Channel 4 Books feels faulty. Nevertheless, she pulls together a lot of information from several twentieth century wars and brings knowledge and opinions up to date, as far as this book, published in 1998, is concerned.
I have done some research into ww1 and it’s psychological effects, and felt that the first few chapters were giving a good overview of that, with the added benefit of individual cases and interviews which I had not known about before. And then the 11/11/18 peace was described as being signed by “Nazi command” (2 years before the party had even been formed and 2 decades before it would have any power), after which I could not be certain about the veracity of any of the details, particularly as I have a lot less basic knowledge about the rest of the conflicts described in the book. There were also a lot of typos and lack of tense continuity and a tendency to forget that in the second half of the 20th century not all those in the armed services were men.
That said, it was fascinating to see how similar the reactions to battle experience were throughout the century. The slowness of the military commands to accept, predict, prevent and take responsibility for PTSD cases was not a surprise, but the fact that after they had done, care which ought to have helped didn’t actually make any difference, was surprising.
Overall, I’d say this is a good first look at the subject, or a good reminder with linking lines of argument, but I would advise double-checking before quoting any facts from the book.
