Query: Poet's War

I didn't know much about World War One. So, I went to the book store. I held this book and John Keegan's in hands. This one was cheaper.When I had finished reading it, I began referring to WWI as the "Poet's War" because apparently it was fought primarily by poet's and philosophers.I finally went and purchased Keegan's book. Read that, not this. It doesn't cover the build up to war as well as Keegans. It doesn't cover the grand sweep of the battles as well as Keegan's. It doesn't explain things as well as Keegan's. It does list a lot more poets who took part in the war.
