It's interesting to see how many veterans were critical of the war memoirs and novels that started appearing in the 1920s (esp. in 1929). I've noted Luce's public criticism in a Belfast sermon, which seems to have been aimed chiefly at Robert Graves' Goodbye To All That. Graves' book also drew the ire of Siegfried Sassoon and Edmund Blunden, who meticulously documented the book's inaccuracies in Sassoon's copy of it.
Wittgenstein was mildly critical of R. C. Sherriff's play Journey's End (1928). According to M. O'C. Drury, Wittgenstein read the play in 1936. Drury quotes Wittgenstein as follows:
Nowadays it is the fashion to emphasize the horrors of the last war. I didn't find it so horrible. There are just as horrible things happening all round us today, if only we had eyes to see them. I couldn't understand the humour in Journey's End. But I wouldn't want to joke about a situation like that. (M. O'C. Drury, 'Conversations with Wittgenstein', Ch. VI in Ludwig Wittgenstein: Personal Recollections, ed. Rush Rhees [Oxford: Basil Blackwell, 1981], p. 144)An early WWI text (1919) was Arthur Graeme West's Diary of a Dead Officer. West was killed on the front in 1917. His diary was edited for publication by his friend, the pacifist and philosopher C. E. M. Joad. There are references to Bertrand Russell in West's Diary (pp. 50-57) . West had been reading Russell's 'A Free Man's Worship' and Justice in War Time. In West, one sees the full disenchantment that is dramatized in many WWI books -- initially a religious patriot who wanted to serve King and country, West became an atheist and seemed on the point of refusing to fight any longer when he was killed by a sniper.
