I will be interested to know what rating you give Eagles over Husky. As far as Maugham's book is concerned, I think it's a "slightly fictionalized memoir". (Which puts in a category with Take These Men by Cyril Joly.) I had already thought that it would be very difficult to invent details without access to war diaries, archival material, history books, and so on, in 1945. I also went and asked Dan Taylor, the curator of the Sharpshooters' museum. He wrote back "I received my copy from John Cloudsley-Thompson, who was very much a contemporary in 4CLY. He was complimentary about Robin’s recounting of events and I believe may have proof read it for him." So that's highly suggestive that Maugham changed the names of people but not events. (He is "Robert" in the book when someone refers to him, instead of "Robin".) I have some really positive things to say about the book - I'll try to write a mini review when I'm done.
