I've read and re-read this book on and off for the past 20 years and it still never fails to move me. Sassoon offers us a window on life 90 years ago that has scarcely been matched (especially when taken in conjunction with the first book Memoirs of a Fox-Hunting Man). Incidentally, to find out more about the real events that inspired Sassoon to write, read "The War The Infantry Knew" by Captain J C Dunn (Sassoon's contemporary in the 2nd Battalion, Royal Welch Fusiliers and known as "Munro" in the book under discussion), in which Sassoon figures and which also contains an unedited first draft of one of the chapters from "Memoirs of an Infantry Officer". As the last old soldiers from the Great War die, it's worth reading this book just to remember what they went through.
